The invention provides a commercial vehicle storage battery control circuit and a control method, the commercial vehicle storage battery control circuit comprises a BMS battery control board, the BMS battery control board is provided with a charging MOS tube Q3 and a discharging MOS tube Q4, the drain end of the charging MOS tube Q3 is in electric signal connection with the drain end of the discharging MOS tube Q4, a capacitor C1 and a resistor R5A are connected between the drain end of the charging MOS tube Q3 and the drain end of the discharging MOS tube Q4, and the capacitor C1 and the resistor R5A are connected with the BMS battery control board. The drain end of the charging MOS tube Q3 and the drain end of the discharging MOS tube Q4 are simultaneously connected with one end of a capacitor C1 and one end of a resistor R5A in an electric signal mode, and the other end of the capacitor C1 and the other end of the resistor R5A are simultaneously connected with the grid end of the charging MOS tube Q3 and the grid end of the discharging MOS tube Q4 in an electric signal mode and connected to an MOS control system. The technical problems that in the long-time charging and discharging process of an existing commercial vehicle power management system, SOC error accumulation is caused by current collection errors, and system functions are damaged due to the lack of an abnormal alarm system are solved. The method can be widely applied to intelligent control of the storage battery in a commercial vehicle.

    本发明提供一种商用车用蓄电池控制电路及控制方法,其包括BMS电池控制板,BMS电池控制板上设有充电MOS管Q3和放电MOS管Q4,充电MOS管Q3的漏极端和放电MOS管Q4的漏极端电信号连接,充电MOS管Q3的漏极端和放电MOS管Q4的漏极端之间连接有电容C1和电阻R5A,充电MOS管Q3的漏极端、放电MOS管Q4的漏极端同时和电容C1、电阻R5A的一端电信号连接,电容C1、电阻R5A的另一端同时和充电MOS管Q3的栅极端、放电MOS管Q4的栅极端电信号连接,并且连接至MOS控制系统。其解决了目前商用车电源管理系统,在长时间充放电过程中,由于电流采集误差导致的SOC误差累计,并且,由于缺少异常报警系统,导致对系统功能造成损伤的技术问题。本发明可广泛应用于商用车中对于蓄电池的智能控制。
