The invention belongs to a power supply protection system and method for doubly limiting the action of a whole forklift, wherein the system is characterized in that the system comprises a lithium battery pack, a lithium battery thermal management module, a lithium battery external output control module, a lithium battery charging and control module, a lithium battery power supply management module, and a lithium battery fault limiting module; and the system is characterized in that the lithium battery pack is electrically connected with the lithium battery thermal management module, the lithium battery external output control module and the lithium battery power supply management module, and the lithium battery power supply management module is electrically connected with the lithium battery external output control module, the lithium battery charging and control module and the lithium battery fault limiting module. Two fault reminding modes of message reminding and hardware reminding are set, the action of the motor controller is doubly reminded, and the stability, diversity and supportability of fault processing are improved. A relay power-off recovery diode is additionally arranged, so that the DCDC service life is prolonged, and frequent maintenance is avoided.

    本发明属于一种双重限制叉车整车动作的电源保护系统及方法,其特征在于包括锂电池组、锂电池热管理模块、锂电池对外输出控制模块、锂电池充电及控制模块、锂电池电源管理模块以及锂电池故障限制模块,其特征在于所述锂电池组分别与所述锂电池热管理模块、锂电池对外输出控制模块和锂电池电源管理模块电连接,所述锂电池电源管理模块分别与所述锂电池对外输出控制模块、锂电池充电及控制模块和锂电池故障限制模块电连接。设置报文和硬件提醒两种故障提醒模式,双重提醒电机控制器动作,增加故障处理的稳定性,多样性,保障性。增加继电器断电回收二级管,提供DCDC寿命,避免经常维护。
