Where is the small battery on the new energy vehicle?

The use of the battery of new energy vehicles and electric bicycles is different, and it is not often necessary to take out the battery for charging, but only to look at the battery when overhauling, so most car batteries are placed in the middle and rear of the battery.

The location of the small battery of each brand of new energy vehicle is different, generally in the engine compartment or under the rear seat;

Generally in the engine compartment.

In the use of pure electric vehicles.

When we found that in addition to the power battery, there is a small 12V battery, the high-voltage electrical system of the power battery, that is, the power battery, which is mainly used to drive the automobile motor, such as starting, accelerating, the large voltage of the power battery is needed to achieve, and it is used in a deep cycle, as well as to supply power to the high-power subsystem, and the low-voltage electrical system is what we often call a 12V small battery, which is usually used in the low-power system of the car, because there are many electrical appliances that are 12V, This design can eliminate voltage conversion, and at the same time, the small battery needs to supply power to each subsystem when the engine is turned off in an emergency, and the brakes must be there, right? You have to have an airbag sensor, right? Speed sensor, instrument panel, lighting system, steering wheel power, can't lie down, right?

In addition, the small battery on the electric vehicle also needs to be given to the car, double flash, lights, instruments, central lock, and vehicle controller, motor control system, and battery management system.

As well as the controller of high-voltage electrical equipment and auxiliary components such as cooling electric water pump to supply power, secondly, before the vehicle is started, the high-voltage power battery is disconnected by default, and the power is not energized by default, so the power is output to the outside world.

Previously, a device was required to turn on the switch of the power battery. Relays are generally used, and the drive of the relay requires another low-voltage 12V power supply, and this low-voltage power supply can be controlled mechanically. Once the switch is turned on, the high-voltage power battery will charge the low-voltage 12V power supply.

This is why in addition to power, a small 12V battery is needed.

1.In the front cabin.

2.Inside the trunk.

Generally these two places, I hope it helps you thank you.

Look, what brand is that?

There are those with a chassis and those with a trunk.

The brand of the vehicle is not the same, and the location is not the same.

Although the new energy battery uses the engine to make the car move, the car has a lot of places to use electricity, so the car must have a battery, but we have no way to charge it.

The engine of the general car is in front of the car, and when the front engine cover is opened, the battery is next to the engine. Or in the area under the passenger seat.

The maintenance-free battery is made of lead-calcium alloy, because the battery uses lead-calcium alloy as the grid, so the amount of water decomposition produced during charging is less, the amount of water evaporation is also low, and the shell adopts a sealed structure, and the sulfuric acid gas released is also very small, so compared with the traditional battery, it has the advantages of not adding any liquid, less corrosion of the wiring pile, wire and body, strong overcharge resistance, large starting current, long power storage time, etc., and has been very popular in China in recent years.

3.Batteries can be roughly divided into two types according to the varieties of existing batteries in the market: traditional lead-acid batteries and maintenance-free batteries that have just been popularized in China in recent years.

The lead-acid battery is composed of positive and negative plates, separators, shells, electrolytes and terminal piles, etc., and the chemical reaction of its discharge is carried out under the action of electrolyte by relying on the active material of the positive plate and the active material of the negative plate, in which the grid frame of the plate is made of lead-antimony alloy. Liquid reduction will occur in the process of use of traditional batteries, which is due to the antimony on the grid will pollute the lead on the negative plate, resulting in excessive decomposition of water, and a large amount of oxygen and hydrogen will escape from the positive and negative plates respectively, so that the electrolyte will be reduced.

There are two types of new energy vehicle batteries, one is the power battery, which is in the chassis of the vehicle. The other is that the vehicle's electrical battery is generally located in the front cabin.

Hello, the power battery system used in new energy vehicles is very large, usually more than 100 kg. In this case, the position of the layout is generally placed under the floor in the middle of the body, that is, hoisted under the floor, typical models such as Honda Outlander PHEV, BMW i3, BYD E6, Qin, F3DM, Mitsubishi IMIEV, Nissan LEAF, GM Volt (its battery pack is a T-shaped structure) and so on, most companies use this method. If the battery pack is small and space allows, you can also consider putting it in the trunk, such as Volvo V60, Toyota Prius, Honda Civic, etc.

Do you know where the battery is when the emergency starts? Different Audi batteries are positioned differently.

In order to ensure safe use, the battery box where the battery is installed must be equipped with ventilation holes and must not be blocked to prevent the gas generated by the battery from accumulating in the battery box.

Generally, there are two positions, one is under the chassis of the carriage. The other is behind the rear seats. The chassis of pure electric vehicles is relatively compact and empty, and the battery is relatively large, so it is basically in the chassis, while the battery of hybrid vehicles is relatively small, and can generally be placed under the trunk or rear seats.

There is a slight difference depending on the type of electric vehicle. In battery-only electric vehicles, the battery is the only source of power for the vehicle's drive system. In hybrid vehicles equipped with conventional engines (or fuel cells) and batteries, the battery can play the role of both the main and auxiliary power source of the vehicle's drive system.

It can be seen that at low speed and start-up, the battery plays the role of the main power source of the automobile drive system; When accelerating at full load, it plays the role of an auxiliary power source; It plays the role of storing energy during normal driving, deceleration, and braking.

Precautions for electric vehicle batteries:

1. Before installation, check whether the battery is damaged and leaking, and clean the surface of the battery with a dry cloth.

2. The battery should be installed upright, not upside down, the spacing between adjacent batteries should be greater than 2 mm wave, and at the same time, it should be shockproof, pressure-proof, and firmly installed.

3. In order to ensure safe use, the battery box where the battery is installed must be left with a ventilation hole, and it must not be blocked, so as to prevent the gas generated by the battery from gathering in the battery box.

4. If the electric vehicle is not used for a long time, it is necessary to put it on hold after the battery is fully charged, and it is strictly forbidden to put it on hold for a long time in the state of power loss.

5. If the continuous charging time of the battery exceeds 10 hours, and the charger still does not convert the lamp to change the seventh battery is hot, it should be immediately forbidden to charge and handed over to the battery after-sales service for processing, and it is strictly forbidden to continue charging under the condition that the charger does not convert the lamp.

6. Different models, different brands, and new and old batteries cannot be mixed.

Hello Car battery location: generally open the front engine cover, the battery is installed in the engine compartment, the battery is next to the engine, or in the area under the passenger seat. Some models have a battery mounted under the spare wheel in the trunk.

Generally, the battery of a fuel vehicle is on the engine side of the front of the vehicle. If it is this kind of pure electric car, it is generally in the chassis.

The location of different cars is different. The trolley is generally placed in front. Large carts are generally placed on the side.

Car battery: location.

In fact, as long as you open your electric car battery box, you can see that there are 3 or 4 batteries in your battery box. This battery is generally 12V, so if your electric car is 36V, it is generally 3 pieces; If it is 48v, it is generally 4 pieces. Then connect these three or four batteries in series with wires.

Generally, the red positive is connected to the black negative electrode, and four batteries can be connected in series.

Car batteries: Precautions for installation.

1. Before installation, check whether the battery is damaged and leaking, and clean the surface of the battery with a dry cloth.

2. The battery should be installed upright, and the spacing between adjacent batteries should be greater than 2 mm wave, and at the same time, it should be shockproof, and it should not be hit by channeling during use.

3. In order to ensure safe use, the battery box where the battery is installed must have ventilation holes and must not be blocked.

4. The battery is charged out of the factory, usually the user can directly load the car for use, if it is shelved for a long time (more than 2 months), it should be charged before use: the charger should be plugged into the battery box and then connected to 220 volts of alternating current, and the charger will continue to charge for 1-2 hours after turning green, and then the charging can be stopped.

5. When the electric vehicle is running, it is best to charge the battery after using about 80-90% of the power, do not charge it after the battery is exhausted, if the battery is exhausted, do not use the battery "back voltage" to force driving, so as to prevent shortening the battery life due to "over-discharge".

The electrolyte in the battery is a strong corrosive acid, do not splash on ** or clothing, if splashed**, the eyes must be immediately rinsed with a large amount of water, and in serious cases, it must be sent to the hospital**. Today, I will tell you where the car battery is located and what precautions are taken during installation, and I will update you with different car knowledge every day.

When the front bonnet is opened, the battery is installed in the engine compartment, next to the engine or in the area under the passenger seat. Some models have a battery mounted under the spare wheel in the trunk.

China is a large country in terms of population and labor force, and the task of employment is arduous. Since the founding of the People's Republic of China, China has actively explored an employment system suitable for China's national conditions and improved a long-term mechanism to promote employment. In particular, since 2002, based on solving the problem of reemployment of laid-off unemployed persons and focusing on the establishment of a market-oriented employment mechanism, China has given priority to the expansion of employment in economic and social development, and on the basis of extensive international experience, it has formulated and implemented an active employment policy with Chinese characteristics, and has helped laid-off unemployed people and other people with employment difficulties to achieve employment and reemployment through measures such as developing jobs, increasing capital investment, granting tax exemptions and exemptions, implementing small loans, and providing social insurance subsidies.

Since 2003, China has listed the number of new urban jobs and the control of unemployment rate as important goals of macroeconomic regulation and control, implemented the target responsibility system at all levels, established an inter-ministerial joint conference on employment, and improved the working mechanism of unified leadership and division of labor. In 2005, in view of the situation and characteristics of employment and reemployment work in the new period, the active employment policy was continued, expanded, adjusted and substantiated, and a series of special policies and measures such as credit, taxes and fees, finance, social security and labor market management services were introduced, forming a complete set of employment and reemployment policy system. In August 2007, China promulgated the Employment Promotion Law, which came into effect on 1 January 2008, marking the beginning of the legalization and institutionalization of China's employment work from policy support.

As a result of these efforts, the scale of employment in China has continued to expand, the employment structure has been continuously optimized, the employment of the needy people has been effectively assisted, public employment services have been increasingly improved, and great progress has been made in vocational training, thus maintaining the basic stability of the employment situation.
