1. Avoid high temperature charging. Do not charge in an environment where the temperature exceeds 40°. High temperature will dim the battery capacity.Try to avoid a cool and ventilated environment. A too hot environment is not conducive to charging, and it will destroy the battery and reduce the life of the charger.In addition, the ambient temperature for charging low-temperature lithium batteries is 25℃.At the beginning, most chargers were not used to the active control system of ambient temperature. Most chargers were planned according to the ambient temperature of 25℃, so it is better to charge at 25℃.

    2. If you do not use electric vehicles for a long time, you should disconnect the battery from the vehicle, and make up some power to the battery at intervals to avoid self-discharge of the battery.Low-temperature lithium batteries are not allowed to be stored by air. If low-temperature lithium batteries are not practical for a short period of time, please charge the battery to the above for storage, and it is necessary to replenish the battery every 30 days.

　　3. When charging the battery, if the charger plug is constantly heating up, and the heating time is relatively long, you need to immediately check whether the plug is short-circuited or poor contact. Pull out the charger and check the plug for oxides, such as rust, and then remove it immediately.
