Anti-theft measures for batteries of electric vehicles;

1. Try to choose high-quality and qualified car locks. Lock the car wherever you go, even if you only leave for a minute. Don't be afraid of trouble, and don't take any chances. If you are away from home and come to a strange place for a long time, lock the car with a lock.

2. There are tricks to lock in which seat of the car. The best way is to lock the car where the front wheel is far from the ground.

3. Choose a good parking place and a safe parking way. For example, it is best to park your car indoors, in a garage or in a supervised parking spot. When parking temporarily, observe whether a camera is installed nearby. If so, put the car in the camera's shooting range. Even if it is stolen, reporting the case and informing the public security personnel of the camera location will increase clues and evidence to solve the case and help recover the stolen vehicle.

4, you can install a GPS locator, such as 360 riding guards and other apps, connect your mobile phone, and locate your electric car anytime and anywhere.

5, choose an electric car with a better anti-theft system, preferring to spend more money.

When the following phenomena occur, it can be judged that the battery life is terminated:

1, the actual discharge capacity of the battery is lower than about 60% of the rated capacity, and it can not be significantly improved after maintenance, so it can be determined to be scrapped. This is because when the battery is in use, the performance will be greatly attenuated after the capacity is attenuated to about 60%, and all components will basically deteriorate. This decay tends to accelerate gradually, and soon it will completely lose its charging and discharging ability.

2, battery charging, serious fever. At the end of the battery life, the positive electrode will be severely softened (the main failure mode), the active material will fall off, the internal resistance will increase, and the impurity elements in the electrode plate will be dissolved continuously, which will increase the gas evolution rate, deteriorate the efficiency and increase the calorific value. At this time, if you open the battery safety valve for inspection, you will see that the electrolyte is "black" and cannot be repaired when it is seriously invalid. At this time, the battery will discharge itself quickly, and sometimes it will be dead soon after charging.

3. The performance of scrapped batteries is greatly reduced, and the performance is extremely unstable, which may cause adverse consequences, such as heating deformation, short circuit, open circuit and even explosion danger during charging. Therefore, when the battery reaches its service life, it should be replaced with a new battery in time.
