The following are the precautions for charging new electric vehicle batteries:
1. It is recommended to start charging when the battery has about 20% remaining power, to avoid completely depleting the battery or being in a depleted state for a long time. The initial charging time usually takes 8 to 10 hours, depending on the temperature. It may be slightly longer in winter and shorter in summer, but it is important to ensure that the charging time does not exceed 12 hours and is not less than 6 hours. It is recommended to charge during the day or indoors to more accurately control the charging time and ensure the safety of the charging environment.
2. The charger and charging environment must use original, qualified, and battery compatible chargers to avoid using inferior or incompatible chargers, which may damage the battery or cause safety hazards. When charging, one should choose a well ventilated, dry, and safe environment, and avoid charging in damp, high temperature, or flammable and explosive environments. Chargers should not be placed on flammable or hot objects to prevent fires. When charging, you should first connect the socket of the electric vehicle, and then turn on the power supply; When disconnecting the charging, the power should be unplugged first, and then disconnected from the electric vehicle.
3. Charging habits and maintenance: Avoid frequent charging and discharging. It is recommended to conduct a complete charging and discharging cycle every month to extend the battery's lifespan. During the charging process, observe the temperature of the battery in a timely manner. When the temperature rises abnormally, stop charging in a timely manner and check the cause. Regularly check the status of the battery, and if any abnormal phenomena are found, replace the battery with a new one in a timely manner. When not using an electric vehicle for a long time, try to keep the battery charged to a certain level. It is recommended to charge it at least once a month to avoid excessive discharge and damage to the battery.
