Abstract: Due to the increasingly complex and intelligent functions of new energy electric vehicles, the number of control components has increased. The problem is that the leakage current of various control components in the vehicle increases during sleep, making it easier for the battery to deplete during sleep. In order to ensure that electric vehicles can maintain their battery life for a longer time without losing power in the event of limited battery storage capacity, this paper proposes a new intelligent battery charging method that utilizes the vehicle controller's timed wake-up function to check the current battery level and decide whether to start the high-voltage battery to charge the battery, in order to ensure that the battery does not lose power during vehicle sleep and prevent the vehicle from starting normally, to solve the problem of battery loss during vehicle sleep. By adopting the intelligent power replenishment method described in this paper, the vehicle control unit is controlled to sleep and wake up at a fixed time, effectively saving the vehicle's electricity while also ensuring the battery's level of power, thus ensuring the normal operation of the vehicle.
