The invention provides a storage battery control system and method for a motor train unit. When the storage battery works normally, the charger is connected with the storage battery, the charger charges the storage battery, after the storage battery is fully charged, the floating-charge-free contactor is disconnected, charging is stopped, and meanwhile it is guaranteed that the storage battery keeps the discharging capacity all the time through the diode connected with the floating-charge-free contactor in parallel; and when the storage battery has a fault and is insufficient in power, the external non-vehicle-mounted charger is connected with the storage battery, and the external non-vehicle-mounted charger charges the storage battery. According to the system and the method, the floating charge condition after the storage battery is fully charged is avoided, and the service life of the storage battery is prolonged.

    本发明提供一种动车组用蓄电池控制系统及控制方法。在蓄电池正常工作时,接通充电机与蓄电池的连接,充电机为蓄电池充电,当蓄电池电量充满后,断开免浮充接触器,停止充电,同时通过与其并联的二极管,保证蓄电池时刻保持放电能力;在蓄电池故障亏电时,接通外接非车载充电机与蓄电池的连接,外接非车载充电机为蓄电池充电。本发明提供的系统和方法避免蓄电池充满电后的浮充情况,延长蓄电池使用寿命。
