With the development of new energy vehicles, the demand for electric energy is also improved. More and more consumers have faced the need for a car battery for the car, while different cars and people are different. 1 Working principle of battery storage battery storage power supply, battery is a device consisting of two substances and electrolytes having conductivity differences.

Battery can store and release electrical energy by an electrochemical reaction. In a typical lead-acid battery, each cell has a voltage of 2 volts, a total of 6 cells, a 12 volt voltage. When any of the load to be electrically connected, such as broadcast, when connected to the battery, the positive and negative end post will immediately form a circuit, thereby current.

Most people don't realize that the lead-acid battery is running in a continuous charge and discharge state. When the battery is connected to the device to be electrically, such as the automotive engine, the current is output from the battery. At this time, the battery starts discharge.

When the car is in operation, the generator is powered to the battery, the battery is in the charging process. When the battery is discharged, the active material reaction on the plate is more active. In the end, the power is exhausted, and the current cannot be output.

You can charge the battery of the loss, a fully chargeable battery, can be charged at any time. The unique charge and discharge process of lead-acid batteries means that electrical energy can be repeatedly stored and released. This is also a well-known battery cycle capacity.

2 Important uses of car batteries Power supply to the starter motor, ignition system, and other equipment when the engine is started. In addition, when the engine is not running or the power generation system output cannot meet the power of the electrical power, the battery can be used in one or time. In addition to the car start, the battery is related to a lot of electrical appliances, such as headlights, lighting, wiper, speakers, navigation, etc.

The battery can stabilize the voltage of these electrical appliances, preventing voltage fluctuations from working abnormal or damage. When the engine is not running, the power of all electrical appliances on the car is supplied by the battery. When the engine is at a low speed, idle, and the output of the power generation system does not satisfy the power of the electrical power, the battery will assist the generator to replenish the electrical appliance.

3 cars can't start properly? Important reasons for battery loss, power generation system failure, can not charge normally, causing battery loss; battery power has been fired by car computer, anti-theft system, etc.; battery has lost storage capacity (failure). Start loops include starters, engine, etc.

The ignition system is like a spark plug, can't fire, etc. Oil road oil road clogging, etc. Temperature extremely low battery capacity is greatly reduced, and the engine has increased the battery supply greater starting power due to the oil viscosity of the oil.

This is very difficult to cut your head. How to deal with? When the battery is unable to start the car, we usually refer to the battery without electricity. However, from the technical point of view, this expression is inaccurate.

Because when the battery is used due to continuous use of the lamp or engine damage, it can also achieve full power by charging. However, when the battery reaches the life of the life, the battery is the true meaning of the actual sense, it must be replaced. If the battery is just a loss, it is not damaged, it can be charged by lapting another full battery.

Alternatively, the car starts about 30 minutes, the engine can also make the battery full of electricity. However, if the engine or electrical system parts are damaged, the battery cannot be recharged, and the repairman and service station are also helpless. Therefore, if the battery continues to discharge, please check the electric vapor system before replacing.

Sometimes, due to the problem of electrical systems instead of battery itself, the battery cannot be charged. If there is a component damage in the electric vehicle system, it will cause the new battery to continue to consume, so that you are constantly caught in trouble. 4 Factors affecting battery life In addition to the design and manufacturing quality of the battery product itself, the actual life of the battery is related to many factors.

Regions with high temperature conditions, the actual service life of the battery will be significantly short. The output voltage of the generator will cause excessive charging, and the pressure is insufficient. The driving habit of the owner When the engine is not running, use the electric appliance on the car for a long time, or often forget the appliance.

Error adaptation of optional capacity is too low to shorten service life. The long leakage of vehicle leakage will seriously change the burden on the battery, which greatly shortens the service life. 5 How to replace the battery? Select the battery, in addition to choose a well-known brand battery for life, temperature difference and earthquake resistance, and choose from the specifications and performance parameters of the battery.

The battery size battery is also a boss. If you buy a fat man, you can't make it unfortunately, so you need to check the physical specifications of the new battery when you purchase the battery, try to choose the same size as the original configuration size. Battery.

Two performance values ​​CCA (cold start current) and C20 (battery capacity index). The battery capacity index C20 (in time is safe), reflects the storage capacity of the battery, the larger the number, the greater the battery capacity. Cold start current indicator CCA of the battery, reflecting the instantaneous start of the battery.

Checking the battery factory date battery is life, so you must be carefully serious and then serious when choosing a battery! It is essential to perform professional voltage detection for new batteries before loading, ensuring that the open circuit voltage of the battery is over 12V of the normal state, and the power is full.
