Electric vehicle lithium battery maintenance tips

During the operation of an electric vehicle, the power of the engine is increased at the start of the low temperature cold vehicle and the complex electrical equipment in the vehicle needs to consume a large amount of electric energy. It is particularly difficult to maintain a reliable charge and discharge balance of the vehicle electrical system, while in the traffic this is even more pronounced when driving in a busy city. During the parking process of the vehicle, due to the self-discharge effect of the battery itself and the sleep current required by the control unit such as theft prevention, the battery always has a certain current consumption. Long-term parking of the vehicle without charging will result in damage to the battery. The characteristics of the battery determine the regular inspection and maintenance.

1) Check the liquid level of the electrolyte regularly according to the manufacturer's instructions. If necessary, add distilled water to the maximum scale.

2) In order to reduce the self-discharge of the battery, the outer surface of the battery should be kept clean and dry.

3) For normal use vehicles, the electrolyte density or open circuit voltage of the battery should be checked regularly. When the electrolyte density is lower than 1.2g/ml or the open circuit voltage is lower than 12.3V, the battery should be recharged to above 12.7V.

4) If the vehicle is idle for more than two weeks, it is recommended to disconnect or turn off the battery main switch; if it is idle for more than two months, the battery should be removed.

5) The battery should be stored at a temperature higher than -10 ° C and lower than 35 ° C, at least once every three months.
