Double protection circuit of low-voltage parallel electric box

The utility model discloses a low-voltage parallel electric box double protection circuit, which comprises a battery pack, a three-terminal fuse and a BMS board, one pole of the battery pack supplies power to the outside through the fuse end of the three-terminal fuse, the other pole of the battery pack supplies power to the outside through the BMS board, the control end of the three-terminal fuse is connected with the driving device pin of the BMS board, and the control end of the three-terminal fuse is connected with the driving device pin of the BMS board. Therefore, the BMS board can drive the three-terminal fuse to be disconnected. It can be seen that through the arrangement of the three-terminal fuse, the three-terminal fuse is connected with the driving device pin in the BMS board, and therefore secondary redundancy protection can be achieved under the conditions that the BMS board is not transformed and an external circuit is not added. 本实用新型公开了一种低压并联电箱二重保护电路，包括电池包、三端保险丝和BMS板，所述电池包的一极经三端保险丝的保险端向外供电，另一
