Car battery is a type of battery. Its working principle is to convert chemical energy into electrical energy.Generally, the battery refers to the lead -acid battery.That is, it is mainly made of lead and its oxides. The electrolyte is a battery of sulfate solution.Let me introduce it in detail below!
Maintenance of car batteries
1. Avoid parking the car in an open -air parking lot for a long time. If it is parked for a long time, the battery must be removed to prevent the battery from being damaged.
2. The car engine is not easy to start in winter. The time for each car will not exceed 5 seconds, and the interval time is not less than 15 seconds.In the case of repeated startups, it is still not on fire, and other reasons should be found from other aspects such as circuit, ignition coil or oil circuit.Avoid non -stop startup, which will cause batteries to burn out due to excessive discharge.
3. Motor batteries should be charged frequently. The battery will slowly discharge without needed until it is scrapped. Therefore, the car should be started every time, charging the battery.
4. Clean the battery of the battery once every time, and apply a special oil to protect the line.Clear accessories and connection lines on the battery.
5. Forbidden to use car electrical appliances after the car is turned off. The engine uses a battery alone without power generation, which will cause damage to it.
6. Eliminate the lights and Guan sound before parking off the fire.After the driving is over, you must turn off the lights, audio, etc. before going out, and then turn off.This will not consume the battery power, especially the lights, turning the lights, etc. After getting off the car, check it out. Dont ignore this. Once the light is turned on for a long time, it is very unfavorable to the battery.When driving at night, pay attention to mobilize the vehicle and then turn on the lights, audio, etc.
7. Avoid air -conditioning without turning off the air conditioner.The electricity consumption of air conditioners is very large. Some car owners are used to the air conditioner at the fire. In this way, the air conditioner is automatically operated next time when the vehicle starts the vehicle.
Automotive battery classification
1. Nickel-cadmium battery voltage: 1.2V service life is: 500 times of discharge temperature: -20 degrees to 60 degrees charging temperature: 0 degrees to 45 degrees Note: Strong tolerance capacity.
2. Nickel-metalized battery voltage: 1.2V service life is: 1000 discharge temperatures: -10 degrees to 45 degrees charging temperature: 10 degrees to 45 degrees Note: The current highest capacity is about 2100mAh.
3. Lithium-ion battery voltage: 3.6V service life is: 500 times of discharge temperature: -20 degrees to 60 degrees charging temperature: 0 degrees to 45 degrees Note: weight is 30%to 40%lighter than nickel-metal hydride batteries, high capacity is high, and the capacity is high.Nickel -hydride batteries are more than 60%.But it is not resistant to overcharging, if the charge will cause too much temperature and destroy the structure => explosion.
4. Lithium polymer battery voltage: 3.7V service life: 500 times of discharge temperature: -20 degrees to 60 degrees charging temperature: 0 degrees to 45 degrees Note: The improvement type of lithium battery, no battery solution, and use 5 to use 5., Electrical, can be made into various shapes, which is stable than lithium batteries.
5. Lead -acid battery voltage: 2V service life is: 200 to 300 times of discharge temperature: 0 degrees to 45 degrees charging temperature: 0 degrees to 45 degrees Note: It is generally car battery (it is connected with 6 2Vs in series,12V), the service life of the water -free battery is up to 10 years, but the volume and weight are the largest.
What are the main functions of automobile batteries
1. When starting the engine, provide a powerful starting current for the starting motivation (about 10A);
2. When the generator is overloaded, it can assist the generator power supply to power equipment;
3. When the engine is at idle, supply power to the power equipment;
4. The battery is still a large capacitor, which can protect the electrical appliances of the car;
5. When the electromotive force of the generator end is higher than the electromotive force of the lead battery, a part of the electrical energy is transformed into chemical energy storage, that is, charging.
