For the first use of a new battery, there is no need to fully drain it before charging. Completely depleting the battery can actually damage it. The battery is a crucial component of an electric vehicle and is also a wear-prone part. As the number of charge and discharge cycles increases, the battery's performance will decline, necessitating regular replacement. Refer to the following charging time guidelines: After full discharge: The typical charging time is around 8 to 10 hours, but it should not exceed 12 hours (as this can affect battery lifespan). It is not recommended to fully drain the battery every time before charging. Generally, it is advised to charge when the remaining power is around 70%, which usually takes about 6 to 8 hours. For short trips: If daily power consumption is around 10%, charge once a week. For 20% daily consumption, charge every three days. For 30% daily consumption, charge every two days. For daily consumption above 40%, charge once a day, controlling the charging time to around 6 hours.
