The electric industrial vehicle emergency power supply system comprises a switch module, when an electromagnetic brake is locked due to lithium battery faults, the switch module is controlled to act so that the first end and the second end of the switch module can be disconnected, and the first end and the second end of the switch module are disconnected; that is to say, an access of the lithium battery for supplying power to the electromagnetic brake through the key switch is disconnected, and then the third end and the fourth end of the switch module are controlled to be closed to connect the access of the power module for supplying power to the electromagnetic brake through the third end and the fourth end of the switch module, so that the electromagnetic brake restores normal power supply, so the electromagnetic brake can release the locking action, a worker can move the electric industrial vehicle where the electromagnetic brake is located at the moment, channel blockage caused by the fact that the faulted electric industrial vehicle is not moved in time is avoided, and logistics efficiency is improved.
本发明公开了一种电动工业车辆应急供电系统及电动工业车辆,包括开关模块,其中,由于锂电池故障导致电磁制动器抱死时,控制开关模块动作以使开关模块的第一端与第二端断开,也即是断开锂电池通过钥匙开关为电磁制动器供电的通路,然后控制开关模块的第三端与第四端闭合,以导通电源模块通过开关模块的第三端与第四端为电磁制动器供电的通路,从而使电磁制动器恢复正常供电,以使电磁制动器可以解除抱死动作,此时工作人员可以实现对电磁制动器所在的电动工业车辆进行移动,以避免由于未及时移动故障的电动工业车辆造成的通道堵塞,进而提高了物流效率。
