电池组发生短路时，且短路电流达到保护电流时，保护板关断输出。短路电流需按电池实际短路值进行设置，不能过大，也不能过小，设置过大，短路达不到短路保护电流，保护板烧坏，设置过小，电池接上车时，会出现短路保护，无法启动电动车

When the PACK is short-circuited and the short-circuit current reaches the protection current, the protection board turns off the output. The short-circuit current should be set according to the actual short-circuit value of the battery. It should not be too large or too small. If the setting is too large, the short-circuit will not reach the short-circuit protection current. The BMS will burn out. If the setting is too small, the battery will be short-circuited when it is connected to the vehicle. Protection, unable to start electric vehicles
