The invention discloses a two-way power supply charging and discharging control system and method for a vehicle storage battery. The method comprises the steps that real-time voltages of a driving storage battery and a parking storage battery, a vehicle starting signal, a vehicle control signal and an internal control signal are collected; according to the collected real-time voltage and signal, a corresponding control signal is output based on a preset control logic; and according to the output control signal, the opening and closing states of the plurality of relays are controlled so as to control the charging and discharging of the driving storage battery and the parking storage battery. On-off of a relay circuit is accurately controlled according to the acquired voltage state of the storage battery, normal discharging use and timely charging of a two-way power supply of the storage battery are achieved, the charging efficiency is improved, the condition of insufficient electricity of a driving storage battery and a parking storage battery is avoided, and the service life of the storage batteries is prolonged.

    本发明公开了一种车辆蓄电池的双路电源充放电控制系统及方法,采集行车蓄电池和驻车蓄电池的实时电压以及车辆启动信号、车辆控制信号和内部控制信号;根据采集的实时电压与信号,基于预设的控制逻辑,输出相对应的控制信号;根据输出的控制信号,控制多个继电器的开合状态,进而控制行车蓄电池和驻车蓄电池的充放电。本发明根据采集的蓄电池电压状态准确控制继电器电路的通断,实现蓄电池双路电源的正常放电使用和及时充电,提高充电效率,避免行车蓄电池和驻车蓄电池出现亏电情况,延长蓄电池的使用寿命。
