Claim 0:
1. An overcurrent protection circuit of a high voltage battery cluster, comprising:
a first fusing module arranged in a positive branch of a switch box of the high voltage battery cluster; and
a second fusing module arranged in a negative branch of the switch box of the high voltage battery cluster, wherein
a withstand current-time curve of the first fusing module is different from a withstand current-time curve of the second fusing module,
wherein under a same withstanding current, fusing duration of the first fusing module is less than fusing duration of a first direct current switch, and fusing duration of the second fusing module is less than fusing duration of a second direct current switch in the switch box of the high voltage battery cluster.
