The invention discloses an electric vehicle automatic charging control method and system. The method comprises the steps: enabling T-BOX to detect the voltage of a storage battery through physical hardware in a dormant state of a whole vehicle, and judging whether the voltage is smaller than a first preset voltage or not; considering certain conditions, if the storage battery voltage is smaller than the first preset voltage; if yes, the T-BOX awakens the whole vehicle network; a power-on remote control instruction is sent to the vehicle body control module; and detecting the voltage of the storage battery after delaying for a first preset time, if the voltage of the storage battery is greater than a second preset voltage, indicating that the charging is successful, and after timing for thesecond preset time, sending a power-off remote control instruction to the vehicle body control module by the T-BOX, so that the vehicle enters a power-off dormant state. The problem that the storagebattery cannot be started due to feeding after being placed for a long time can be solved.
本发明公开了一种电动汽车自动补电控制方法及系统,该方法包括:在整车休眠状态下,T‑BOX通过物理硬件检测蓄电池电压,判断电压是否小于第一预设电压;在满足一定条件下,若蓄电池电压小于第一预设电压,则T‑BOX唤醒整车网络,并向车身控制模块发送上电远程控制指令,在延时第一预设时间后检测蓄电池电压,若蓄电池电压大于第二预设电压,则代表补电成功,并在计时第二预设时间后,T‑BOX向车身控制模块发送下电远程控制指令,以使车辆进入下电休眠状态。本发明能够解决蓄电池长期放置后因馈电而无法启动的问题。
