Reasons for premature battery life of electric vehicles.

1. The car owner has no awareness of battery maintenance, causing serious damage to the battery. You have to wait for the battery to run down before you come to repair and maintain it. At this time, it is more difficult to repair. In fact, if the car is serviced once every six months, the life will be much longer, but the car owner doesn't have this awareness. The battery damage mostly starts from excessive water loss caused by the charger.

2. Chargers are killers. There are inferior chargers and aging chargers. These battery killers generally play a killer role after 8 months of battery life. The reason is that the new battery meets the taste of these battery killers. With the aging of the battery, the battery cannot meet the requirements of the killers. By June of each year, the battery quickly loses water and is discarded.

3. The starting current of luxury electric vehicles is high, which causes the battery to be vulcanized. If the owner starts the car and accelerates slowly, the battery life and driving mileage will increase by 20%.

4. The motor controller is damaged, resulting in short battery life. The probability is small, but there are many.

5. Ride without losing power, and life is naturally long. The new battery can be charged every time it is used above the red light, but it cannot be driven with low power. Every time you lose power, your life will be shorter. The new battery with 10 times of power loss will also be scrapped quickly. You should charge it in time to avoid power loss. [3]

6. The most important point is to charge properly: some people say that "the battery is not used out but charged out", which is really correct. The charging performance of the battery plays an important role in the service life and performance of the battery, so we must pay attention to the charging mode. According to the situation of most users, it is the best choice to charge the battery once when the discharge depth is 50% - 70%, so that the battery life can reach the best effect. At the same time, temperature has a considerable impact on charging. In high temperature season, the battery is overcharged. The temperature of the battery should be reduced as much as possible to ensure good heat dissipation and prevent charging after exposure to the sun. Exposure to the sun will increase the temperature of the battery, increase the activity of various active substances of the battery, and affect the service life of the battery. On the contrary, at low temperature, the battery has the problems of poor charging acceptance and insufficient charging. In this case, it is necessary to increase the charging voltage and extend the charging time, and take thermal insulation and antifreeze measures, which is conducive to ensuring sufficient power and extending the service life of the battery.
