The invention provides a vehicle-mounted terminal T-BOX standby battery charging method and system. When the vehicle-mounted terminal T-BOX is powered on, the internal resistance value of the standbybattery is detected, and when the CPU control unit detects that the internal resistance value is lower than the internal resistance value of the standard battery, the CPU control unit sends a controlsignal to the alarm module to control the alarm module to give an early warning of reminding of battery replacement; the voltage of the T-BOX standby battery is sampled in real time through the AD sampling module, multi-stage charging and charging stopping are carried out for the voltage value range, the charging flexibility of the vehicle-mounted T-BOX standby battery is improved, and the servicelife of the battery is prolonged.

    本发明提供了一种车载终端T‑BOX备用电池充电方法和系统,当车载终端T‑BOX上电时检测备用电池内阻值,当CPU控制单元检测到内阻值低于标准电池内阻值时,CPU控制单元向报警模块发送控制信号,控制报警模块发出提醒更换电池预警;通过AD采样模块实时对T‑BOX备用电池的电压进行采样,针对电压值范围进行多段式充电和停止充电,提高了车载T‑BOX备用电池的充电灵活性和电池的使用寿命。
