Abstract
A high voltage battery cluster, and an overcurrent protection circuit and a switch box of the high voltage battery cluster are provided. The overcurrent protection circuit includes a first fusing module and a second fusing module. Since a withstand current-time curve of the first fusing module is different from a withstand current-time curve of the second fusing module, in a case that an overcurrent fault occurs in a high voltage battery cluster, one fusing module can cause an open circuit in the high voltage battery cluster prior to another fusing module, thereby preventing the high voltage battery cluster from being broken by a large current when an overcurrent fault occurs in the high voltage battery cluster, thus ensuring an electrical safety of the high voltage battery cluster.
