At this stage, the energy density of power batteries is getting higher and higher, and the capacity of single cells is getting larger and larger. Once the high-voltage components are short-circuited without corresponding protection measures, the components will be damaged at light, and fires (especially power batteries) will be caused in severe cases. The consequences will be unimaginable, so the protection of each high-voltage component circuit is very important.
Fuses are mainly divided into:
Ordinary fuse (gG/gL), fast fuse partial range protection (aR), fast fuse full range protection (gR), Time-delay type and special fuse
