What should be the fuel consumption of a 150-horsepower two-liter engine that accelerates a two-ton crossover Mazda CX-5? It would seem - not small. But in fact, thanks to an intelligent smart system i-stop, which turns off the car engine even with short stops, work on Idling is reduced to a minimum. The result - the CX-5 engine consumes about one and a half times less fuel than its "classmates" ( Nissan x-trail, Tiguan, Audi Q3, Q5). However, frequent stops / starts of the engine place special demands on the power supply of the car.
Influence of the i-stop system on Mazda CX 5 battery
It is known that the battery gives the maximum current when the engine is started. Further, its partial discharge is compensated by recharging from the generator. If this is followed by a long trip on the highway, then the Mazda CX-5 battery is charged in the usual auto mode for most. When driving in an urban cycle, each stop of the car starts the i-stop system, and the generator stops working. The battery for Mazda CX-5 with i-stop, in addition to the function of the energy source for the subsequent start of the engine, is also superimposed on the power supply functions for all on-board systems of the car - audio system, climate control system, diagnostic systems, electrical sensors, external lighting devices and interior lighting, glass heating and mirrors, heated seats, etc.
Influence of the state of charge of the battery on the operation of the i-stop system
Not only i-stop affects the battery for Mazda CX-5. There is also a feedback - the operation of the i-stop depends on the state of the battery charge. The parameter characterizing the state of charge of the battery is expressed as a percentage and is called State of charge or simply SOC. For the i-stop system to work correctly, the SOC must be above 85%. And if the SOC is less than 68.4%, the i-stop stops working altogether.
Smart charging of the CX-5 battery
It is impossible to fully compensate for the loss of electrical energy during the operation of the i-stop system in the urban cycle, but Mazda engineers took care that even with frequent shutdowns / starts of the engine, the battery Mazda CX-5 2.0 standard configuration received maximum recharge. This was achieved through the introduction of the so-called intelligent charging system (smart charging).
When the car decelerates, caused by a decrease in the supply of fuel to the engine cylinders or by braking the car (by braking or by braking the engine), the current sensor automatically increases the voltage of the generator, thereby allowing the accumulation of additional electrical energy to charge the battery. In addition, Smart Smart Charging harnesses the vehicle's kinetic energy, reducing the load on the alternator, which also contributes to fuel economy. Of course, "fast charging" with high currents is not the best The best way preserving the long-term operation of any power source, but so far nothing better has been invented in this area.
IMPORTANT! USING THE “QUICK CHARGE” MODE WHEN CHARGING WITH THE CHARGER IS NOT ALLOWED. IGNORING THIS NOTICE MAY LEAVE THE I-STOP SYSTEM.
Charging the Mazda CX 5 Battery at Home
The intensity of the discharge depends on many factors. These include: turning on the burglar alarm, opening / closing doors / hood, the position of the automatic transmission lever (to minimize leaks, it is recommended to leave an unexploited car with the automatic transmission lever set in the "P" position), and even the presence of the key to access the vehicle in or near the vehicle interior ("Wearable card"). Therefore, the vast majority of Mazda CX-5 owners will sooner or later need additional charging of their car's battery. It is quite possible to do this at home with the help of a special charger... Operation manual (manual) Mazda CX-5 recommends performing this procedure every 2-3 weeks.
Consider how to charge the battery on the Mazda CX 5.
First, you need to establish the very fact of the need to charge the battery, i.e. evaluate SOC. This is done by measuring the density of the electrolyte with a hydrometer. In this case, one should remember about the influence of the ambient temperature on this indicator. You can compare the density of the electrolyte at a given air temperature with the SOC indicator using tables that contain special reference books, both printed and online.
For example, at an ambient temperature of 20 degrees, SOC = 100% will correspond to an electrolyte density of 1.280 g / cm3, SOC = 85% - 1.262 g / cm3, 65% - 1.234 g / cm3, respectively. At a lower ambient temperature, the density of the electrolyte corresponding to a certain SOC level will be higher, at a higher temperature, it will be lower. It is not necessary to have a complete table of correspondences of electrolyte gravity to SOC levels at different temperatures on hand. It is enough to remember the reduction formula:
Electrolyte density (at t = 20 o C) = measured density value + (actual OS temperature - 20) x 0.0007.
Before charging your Mazda CX 5 battery, mark the battery bank that is most discharged. Based on the density of the electrolyte in it, the battery charging time is selected from the tables. For example, a density of more than 1.24 means that the charging time will be 180 minutes, while a density of 1.17 will take 360 minutes to fully charge. Charge should direct current 10 amps, checking and adjusting (if necessary) amperage every 60 minutes.
Evaluation of SOC (by density of electrolyte) is carried out 6-48 hours after the end of charging. If the density of the electrolyte in one of the cans is less than 1.25, then you should think about buying a new battery.
In the autumn-winter period, the number of electricity consumers increases significantly. An additional load is provided by the above-mentioned climate control, heated glass and mirrors, heated seats, as a result of which the discharge occurs much faster in winter than in summer. At one point, the car may simply not start. Some motorists in this situation work proactively - they turn off the i-stop. You can completely forget about fuel economy in this situation. The car engine and power supply of the Mazda CX 5 operate in the same mode as in hundreds of other car models. Option two - to purchase and always carry with you an external source of electricity - an autonomous starting and charging device. This will allow, if necessary, to carry out an emergency start of the car engine.
A modern autonomous starting-charger (booster) does not take up much space. It can be used, if necessary, both to start the internal combustion engine and to replenish the charge of a standard energy source. After starting the engine, the charge of its own booster can be replenished immediately by connecting it to the car's electrical network through the cigarette lighter socket.
Replacing the Mazda CX-5 battery
It is very important to keep track of the battery charge level. If the SOC falls below 25% (the density of the electrolyte before charging is below 1.17), battery recovery will already be very problematic. Irreversible changes take place in the plates, which will not allow them to accumulate and hold for a long time the charge necessary for the stable operation of the i-stop system.
How to change the battery for a Mazda CX 5
The procedure for replacing the battery on the Mazda CX 5 is very simple. The first step is to remove the old battery:
1. Disconnect the current sensor from the negative terminal. This will de-energize the on-board computer, preventing the possible passage of an erroneous engine control signal.
2. Remove the negative terminal.
3. Remove the positive terminal.
4. Remove the retaining strip.
Set new battery Mazda CX 5 follows 1 minute after removing the old one. During this small time gap, information about the state of the old battery will be deleted from the memory of the PCM (Powertrain control module - aka "brains"). Installing a new battery is performed in the reverse order of removal.
After installing a new storage battery, it must be "registered" in the system:
1. With the engine off, set the engine start switch to the ON position.
2. Set the automatic transmission lever to the "neutral" position.
3. With the brake pedal depressed:
- press and hold the gas pedal for at least 5 seconds. The battery charge indicator and the main warning indicator should start flashing;
- press and release the gas pedal three times. The battery charge indicator and main warning indicator should go out.
If the Mazda CX-5 is equipped with an LCD display in the instrument cluster, before setting the engine start switch to ON, all doors must be closed, after installation, wait for the warning message to appear on the display, and then delete it with the INFO switch located on the steering wheel.
To check how correct the initialization of the Mazda CX-5 battery was, you must turn on the ignition, then press and hold the i-stop switch for 10 seconds. A blinking green indicator will mean that the battery initialization procedure has been successfully completed. A blinking yellow indicator means undercharge or overcharge of the battery. A permanently lit yellow indicator means that the initialization of the battery in the system has not been completed, it must be repeated.
For correct initialization of the battery, its SOC must be more than 75%.
What kind of battery can be installed on the Mazda CX-5
Taking into account the specifics of the i-stop system, the manufacturer strongly recommends using the original Mazda CX-5 battery, the article of which can be specified in the Mazda catalogs. In addition, you can obtain comprehensive information on which battery to supply your Mazda CX-5 with from an authorized Mazda service center. Initially off the assembly line Mazda crossoversСХ-5 were equipped with 65-ampere batteries GS Yuasa Q-85... Today, the range of batteries allowed for installation has expanded significantly. You can find out which battery is in the Mazda CX 5 by examining the sticker on its case. When choosing a battery different from the one that the car was equipped with on the conveyor, take into account not only the capacity and starting current (for models with a two-liter engine - starting current 540 A * h, for engine models with a volume of 2.2 liters - 640 A * h), but and type ( AGM / EFB).
It is very important to pay attention to dimensions... The extremely dense arrangement of the engine compartment obliges them to withstand them especially carefully. Owners of a two-liter engine should choose a battery corresponding to the dimensions of 202 x 230 x 172 mm (height x length x width), a 2.2-liter model will ask for a longer niche - 202 x 255 x 172 mm - battery marking
The i-stop system is installed on Mazda CX-5 cars of the last years of production. Many are interested in what it is, does the system benefit the car owner, and can it be turned off?
What is i-stop
The i-stop system (i-stop) of the MazdaCX-5 is a function of intelligent stop and restart of the engine, a proprietary development of the Mazda company. To briefly describe the principle of the system's operation, it is as follows.
The car engine automatically shuts off in traffic jams, at traffic lights, when the car stops, and then automatically restarts when the driver wants to continue driving.
In more detail, the logic of the system operation is presented in the table.

The engine will stop automatically when all conditions are met, depending on the availability of climate control and the type of gearbox.
Advantages and disadvantages of the system
The main purpose of the i-stop system is to save fuel, reduce noise and harmful emissions into the environment. In addition, the i-stop regulates the power of the generator (intelligent charging system), because highest consumption electricity falls on starting the engine, and the loss of charge must be quickly replenished.
At the same time, the i-stop solves the problem that it itself creates: it is the repeated repetition of the start-stop cycle that increases the load on the battery, which also takes over the power supply of all boron systems of the car when the engine is stopped.
It must be admitted that multiple repetitions of starting and stopping the car noticeably reduce the engine resource.
This is not so critical when driving on a highway, where the car moves continuously for most of the way at an approximately constant speed. But, as practice shows, most Mazda CX-5 owners use vehicle in an urban environment, where a stop is replaced by a resumption of traffic with sufficient regularity. And if it gets stuck in a traffic jam, the engine can turn off and start several dozen times in a row, which will not add to its “health” at all.
In addition, many Mazda CX-5 users are unhappy with the i-stop system for purely psychological reasons. Not everyone likes "very smart" modern cars... Many old school drivers want complete control over every aspect of their iron horse.
How to disable permanently
One way or another, many are wondering how to disable i-stop permanently. The manufacturer did not foresee such an opportunity, so the home-grown "kulibins" got down to business.
The car owners forums are considering different ways... The easiest is to disable the battery charge sensor. But at the same time, the driver himself is left without information about the battery charge, which, for obvious reasons, is unacceptable.
Various change options electronic circuits require specific skills and abilities. We propose to solve the problem programmatically. For this you will need:
- notebook;
- ELM327 adapter;
- program
The essence of the method is as follows. The SSU software module differs from Mazda CX-5 models with and without i-stop system:
Module view SSU for a car with an i-stop system.
View of the SSU module for a vehicle without an i-stop system.
The task is to change the module by changing the specified values.
- We connect the laptop to on-board computer vehicle through the adapter and launch the FORScan program.
- We find in the menu the item indicated in the figure.
Module SSU in a programme FORScan .
Before making any changes, be sure to make a backup of the module!- Change the values of the leftmost cells in the top two rows.
Before the changes.
After the changes.
That's all! You can turn off your laptop, turn off and turn on the car ignition. After initializing the system, the Mazda CX-5 is ready to use!
The advantage of this method is that no physical changes are made to the car's device, and all program actions are completely reversible.
How useful the i-stop system is in general is a matter of debate. Many believe that the developers have sacrificed the engine resource for the sake of imaginary fuel consumption and fashionable environmentalism. In any case, it is your choice whether to use certain features of your personal car.
Mazda CX-5 in all trim levels has an i-stop system (analogue of a start / stop engine), what is it for? After the engine has warmed up, the i-stop system automatically turns it off when the car stops at a traffic light or in a traffic jam, and then automatically restarts the engine to continue driving. This system is designed to enhance fuel efficiency, reducing the emission of exhaust gases, as well as reducing the noise level during the period when the engine is not running.
Engine stop and restart function (Vehicles with manual transmission)
1. Press the brake pedal, then depress the clutch pedal and bring the vehicle to a complete stop.
2. After the vehicle comes to a stop, hold the clutch pedal depressed and place the gear shift lever in neutral. When the clutch pedal is released, the i-stop activation indicator light (green) will come on and the engine will automatically stop.
3. To restart the engine, depress the clutch pedal (the green i-stop indicator will go out).
The function of stopping and restarting the engine (Cars with automatic transmission)
1. The i-stop system turns off the engine when, while driving, the driver presses the brake pedal and the car stops (except when the car is moving reverse). During the operation of the i-stop system, the indicator light for its activation (green) turns on.
2. After the driver releases the brake pedal when the automatic transmission selector lever is in the D / M position (but not in the fixed second gear position), the engine will automatically restart and the i-stop indicator (green) will turn off ... If the automatic transmission selector lever is in the N or P position, the engine will not restart even after the brake pedal is released. The engine will start after pressing the brake pedal again 
Why i-stop doesn’t work, the engine doesn’t stop (doesn’t turn off)
The following are excerpts from the Mazda CX-5 user manual:
To ensure a safe and comfortable operation In the vehicle, the i-stop system controls the stop and automatic restart function of the engine, constantly monitoring non-driving events, such as the environmental conditions inside and outside the vehicle, as well as the operating status of the vehicle systems. The engine stops automatically when all of the following conditions are met:

How the i-stop CX-5 system works
(youtube) XqcF8iuwek0 (/ youtube)
The Japanese crossover is equipped with a large number of modern electronics, the proper operation of which largely depends on the quality and capacity of the battery. Right choice and installing a battery will help to avoid troubles on the road associated with the failure of the main components. The specificity of the Mazda CX-5 battery is the i-stop system. In this article we will tell you everything about the features of the battery, give advice on choosing, share instructions for self-replacement and battery registration.
How does the battery work
The original Mazda CX-5 battery is installed by the manufacturer. He is responsible for the performance of all electrical components in the vehicle. If the battery malfunctions, it is impossible to start the car. Let's see what the principle of operation of this small but very important component is.
The functioning of a battery is entirely based on the conversion of chemical energy into electrical energy and vice versa. In addition, the device provides a constant current, and it is thanks to the voltage stabilization that the motor can work normally.
The battery is equipped with two poles - positive and negative. The battery terminals are connected to the car, due to which the main mechanisms can perform their tasks without fail. Components that depend on an additional energy source include:
- engine;
- audio system;
- air conditioning;
- optics;
- wipers, etc.
The principle of operation of the battery lies in the peculiarities of its structure. Often, a part consists of 6 cells, in each of which 2 electrodes from metal plates are placed. This galvanic cell supplies power to the vehicle.
Battery operation in i-stop mode
The battery for the Mazda CX-5 car is subjected to enormous loads due to the operation of the i-stop system. This is due to the constant shutdown and start of the engine while the car is stopped. Thus, the owner gets lower fuel consumption due to increased wear of the battery.
The largest consumption of current is carried out at the moment of starting power unit... In the future, the partial discharge of the battery is compensated by recharging from the generator. When driving on the highway, the crossover battery is charged in standard auto mode, and each stop in the city activates the i-stop (while the generator does not work).
The effect of the i-stop depends on the degree of charge. If the SOC is below 65%, the system refuses to function.
The procedure for disconnecting, connecting and replacing the Mazda CX-5 battery
The need to replace the battery with a Mazda CX-5 appears when the SOC charge level drops below 25%. With such an indicator, recovery becomes impossible. Even an inexperienced car owner can independently install, connect or remove the Mazda CX-5 battery.
To dismantle the old battery you need:
- Disconnect the current sensor from the negative terminal to de-energize the on-board computer.
- Remove all terminals.
- Remove the fixing bar.
The installation of the battery is carried out in the reverse order. The next step is registration and initialization of the battery.
Registration and initialization
In order for the battery to work properly, you need to know how to register the Mazda CX-5 battery. The procedure differs depending on the availability of an LCD screen. So, owners of a car without a TFT LCD must follow the instructions:
- turn off the engine;
- move the gearshift lever to position N;
- press and hold the brake pedal while performing further actions;
- by long pressing the gas to activate the battery indicator;
- press and release the accelerator three times to deactivate the light bulb;
- release the brake.
For a TFT LCD crossover, the circuit is as follows:
- close the doors;
- switch the ignition to ON position without starting;
- remove the warning message with the INFO switch;
- set the gearshift lever to neutral position;
- hold the brake pedal in the following steps;
- turn on the accelerator for 5 seconds, wait for the indicator to activate;
- Press and release the gas 3 times (the beacon should go out).
Also, after connecting a new battery and registering it, it is necessary to initialize the Mazda CX-5 battery, since when the terminals are disconnected, the settings are reset. The algorithm is as follows:
- start and warm up the engine;
- hold and hold i-stop for 10 seconds;
- with the hood closed, turn the steering wheel from one extreme position to another;
- turn off the engine.
You can check if initialization has been completed by pressing the i-stop button. If a green light comes on, it means that the battery has fit into the work of all systems.
How to choose a battery for Mazda CX-5
The Japanese brand recommends installing the original Mazda CX-5 battery. This is due to the i-stop technology, on which the operation of the power unit of the machine is based. You can consult an authorized service center for the model. The first generation crossover was equipped with Panasonic Q-85 battery, but today the range has grown significantly, and such well-known brands as Exide, Bosch and many others have entered the market.
To understand which battery is on the Mazda CX-5, you need to carefully study the labeling from the manufacturer. When choosing, it is important to pay attention to the overall dimensions, capacity and starting current. The battery capacity should be in the range of 40-70 A / h, the nominal voltage is 12 V, the starting current is 300-700 A. You should also carefully consider the polarity of the device, the coincidence of the terminals. With regard to dimensional characteristics, the small engine compartment requires them to withstand especially clearly. Owners of the 2.0 engine buy batteries 202x230x172 mm (VxLxW), for 2.2 liters they choose 202x255x172 mm. The cost of the new CX-5 battery starts at 6500 rubles.
Battery marking, reviews
In order not to get confused by the abundance of assortment and purchase a suitable part, it is important to be able to read the labeling. The manufacturer puts a code on the product, decrypting which you can find out the main specifications goods.
What is indicated on the battery label Japanese brand(JIS standardization):
- battery capacity Mazda CX-5;
- battery width, mm;
- battery length, cm;
- terminal arrangement, polarity (L or R).
According to the reviews of car owners, it was possible to find out that the Varta and Bosch brands are the most popular in Russia. These brands offer quality products at a competitive price. Good demand is noted for the Bosch S4 02 model (has an indicator starting current- 540 A and a capacity of 640 Ah). You need to understand that a car with a lot of electronics requires the installation of a high-capacity battery.
Possible problems
Like any part, the battery sooner or later becomes unusable. If the car does not start (especially in frosty weather), it is worth checking the battery performance. Possible problems:
- Battery swelling. If the case is swollen, the device must be replaced urgently. Deformation can be caused by elevated operating temperatures.
- Unpleasant sulfur smell. This is a battery leak. Breakage is also accompanied by the appearance of rust on the terminals.
- Low fluid level. If the amount of liquid has dropped below the lead plates, top up or replace the battery.
In order for the battery, and with it all the electronics to function properly, it is necessary to carry out diagnostics. Breakdown can be provoked by: violation temperature regime during operation, insufficient charging, poor-quality electrolyte and much more.
Outcome
Battery operation provides engine starting and power to all electronic systems... To extend the life of the battery, it is important to charge it on time and adhere to the operating modes. If the need for replacement has already arisen, it is not necessary to seek help at the service station. Installation, registration and initialization can be carried out independently even by an inexperienced car owner.

Japanese cars are equipped with a large number of electronic components, which are powered by a battery. Therefore, choosing and installing the correct storage element will allow you to power up the entire electronic filling and prevent problems with failures in the work of some teas. The main feature of the battery on the Japanese crossover is the i-stop system.
What is the battery in the Mazda-SH5
The original Mazda CX-5 battery is installed during assembly. This storage element is necessary for the operation of the car electronics. If the battery is damaged, it is impossible to start the car engine.
The storage cell works by converting chemical energy into electrical current. This ensures that the components are supplied with direct current. Due to the stabilized power, a normal engine start and the performance of all electronic filling are ensured. Structurally, it consists of two poles, the contacts of which are connected to the car's probes.
In the car, the following components are powered by the battery:
- Motor.
- Sound system.
- Optics, screens and other parts.
- Interior cooling and heating system.
- Wipers.
For installation on a Japanese crossover, it is recommended to install an original galvanic cell. This feature arises from the built-in i-stop technology, which controls most of the drive's operation. It is advisable to undergo diagnostics at service centers before buying. Early versions of the car came with a Panasonic Q-85 battery. However, with the extension lineup the number of possible electrochemical cells has also increased.
To select the right battery, you will need to study the marking of the manufacturing plant, which is usually attached to the battery case. The most important parameters when choosing are the dimensions of the case, the maximum capacity and voltage for starting. Japanese crossover batteries have the following specifications:
- Maximum capacity from 40 to 70 Ampere * hours.
- The output power is 12 volts.
- Electric current for starting 300-700A.
During the selection, it is worth paying attention to the polarity of the unit and the coincidence of the connected contacts. The dimensions of the battery are determined by the volume of the engine. Since the Japanese crossover is produced with an engine capacity of 2 and 2.2 liters, the dimensions will differ:
- For two-liter engine you will need to choose a battery with dimensions of 202x230x172 millimeters.
- The 2.2 motor starts from a battery with dimensions 202x255x172 mm.
The cost of batteries with similar characteristics starts at 7,000 rubles.
Battery replacement
The need to change the outdated battery for the Mazda CX-5 arises when the maximum power level drops below 25%. The container can be installed using a load plug or in another way. A battery that has lost more than three quarters of its charge cannot be recovered. The design of the car is simplified, so installation can be carried out even without experience.
The battery replacement process includes:
- You must first disconnect the electric current sensor from the negative contact of the old battery to turn off the power to the on-board computer.
- Disconnect all terminals.
- Then, you need to remove the bar for fixing.
Then, you need to wait about 5-10 minutes until the PCM memory is cleared. Then install the new battery in the reverse order of removing the old one.
Battery initialization
The action is carried out after connecting the battery and registration. The i-stop system requires a new battery to be initialized. Removing the battery will reset the settings, so some action is required. Initialization instruction:
- Start engine and allow to rev.
- Then, press and hold the i-stop button in this position for 10 seconds.
- On a car with a closed hood, you will need to turn the steering wheel completely.
- Then stop the engine.
After that, it is possible to check the success of the process by pressing a key that corresponds to the control of the i-stop system in the computer. When a green indicator appears, the battery is working normally.
How to prescribe
For correct operation of the replaced battery, it must be registered in the system. Depending on the presence or absence of the screen, the action will be different. For vehicle owners without an LCD panel, the following is required:
- Stop the engine.
- Hold and do not release the brake pedal while performing the following steps in the order;
- Then you need to press the gas pedal until the indicator is activated.
- Then press the accelerator three times until the indicator light turns off.
- Take your foot off the brake pedal.
If you have a screen, you will need:
- Close the salon.
- Switch the ignition mode to the on position without starting the engine.
- Remove all required messages from the screen.
- Change into neutral.
- Next, press the brake pedal and hold it until the end of the procedure.
- Run the accelerator for 5 seconds until the indicator comes on.
- Then press the gas pedal three times. The indicator light will go out.
After that, you will need to carry out the initialization procedure.
Accumulator charging
- Always use a 10A constant current charger.
- In the absence of such a charger, you will have to regulate the supply of electricity.
- Pay attention to the polarity when connecting.
- The duration of charging is influenced by the density of the substance that transfers current inside the battery.
- After a full charge, you need to leave the vehicle for several hours.
Charging optimization
To increase the charge time and reduce the rate of self-discharge, you will need to follow some recommendations:
- Disable parking lights, a radio tape recorder and other devices that waste energy.
- Avoid frequent complete discharge of the battery.
- Do not leave the vehicle in the cold.
- Avoid prolonged downtime and the car with the key in the lock.
- Always close the vehicle.
Charging system malfunctions
The appearance on the instrument panel of an indication of a battery malfunction may indicate:
- Discharged battery.
- Problems in the generator.
- Signs of an imminent exit from a standing galvanic cell.
To fix it, you either need to charge the car, or carry out a comprehensive diagnosis in service center with the subsequent replacement of the battery.
How to properly operate
For a long battery life on a car, you must follow all the recommendations for charging and storage listed by the manufacturer of the galvanic cell, and avoid excessive discharge. It is undesirable to leave the car open for a long time, or leave it on the streets overnight. Low temperatures have a negative effect on the electrolyte.
Influence of the I-Stop system
The control system increases the load on the battery during operation. It is carried out due to the constant start and stop of the motor at stops. Therefore, due to the reduction in fuel consumption, the load on the storage battery is greatly increased.
The maximum load on the galvanic cell is carried out during engine start. Then, the loss of charge is slightly offset by the operation of the generator while driving.
Stabilization and initialization
Work rechargeable batteries is based on mutual transformations of energy. In this case, a constant voltage is supplied to the output, which is necessary for the operation of the electronic components of the car. With a decrease in capacity, the output voltage may accordingly change, which will negatively affect the performance of the on-board computer.
