Abstract
A safety secondary battery pack formed by bridge connection of secondary battery cells and fuses is provided with a plurality of secondary battery cell groups and fuses, wherein the secondary battery cells and the fuses are connected in bridge mode, each of the positive or negative terminals of the secondary battery cells is provided with a fuse. Hence, the respective battery cell groups of the present invention can still work properly in the case that any single battery cell fails. When any of the secondary battery cells fails and the current flowing through the fuse exceeds the rated value, the fuse electrically connected to the failed secondary battery cell will be blown to stop current from flowing, so that the failed secondary battery cell is isolated from the rest good secondary battery cells to improve safety of the battery pack.
