The invention provides a new energy vehicle storage battery charging method and system, and the method comprises the steps: enabling a vehicle-mounted T-Box to be locally awakened every morning when a vehicle is in a power OFF mode and the vehicle is fortified, detecting the voltage of a B + port of the vehicle-mounted T-Box, and enabling the vehicle-mounted T-Box to awaken a whole vehicle CAN network and an electric quantity sensor when the voltage is smaller than a set voltage value; the vehicle-mounted T-Box judges whether a charging condition is met or not according to the precision of the electric quantity sensor, the electric quantity of the storage battery and the health state of the storage battery, if yes, the next step is executed, and if not, the storage battery is not charged; the vehicle-mounted T-Box sends a charging request signal to the vehicle-mounted controller, if the vehicle-mounted controller feeds back a charging allowing signal to the vehicle-mounted T-Box, the storage battery is charged, and charging of the storage battery is stopped until a charging quit condition is met; and if the charging request is not allowed, the storage battery is not charged. According to the invention, the situation that the vehicle cannot be started is not easy to occur.

    本发明提供了一种新能源汽车蓄电池补电方法及系统,其中方法包括:车辆在电源OFF模式且车辆设防时,每天凌晨车载T‑Box本地唤醒,检测其B+端口的电压,当该电压小于设定电压值时,车载T‑Box唤醒整车CAN网络和电量传感器;车载T‑Box根据电量传感器的精度、蓄电池的电量、蓄电池健康状态,判断是否满足补电条件,若为是,则执行下一步,若为否,则不对蓄电池补电;车载T‑Box向整车控制器发送补电请求信号,若整车控制器反馈允许补电信号给车载T‑Box,则对蓄电池补电,直至补电退出条件被满足,停止对蓄电池补电;若补电请求不允许,则不对蓄电池补电。本发明能够使得车辆不易出现无法启动的情况。
