LITHIUM IRON PHOSPHATE BATTERY PACK MODULE OF LARGE-CURRENT DISCHARGE TECHNOLOGIES

摘要

A lithium iron phosphate battery pack module of large-current discharge technologies comprises a lithium iron phosphate battery pack (101) and a battery pack control circuit that are electrically connected. The lithium iron phosphate battery pack comprises several single lithium batteries (1011) connected in series. A shorting piece (1012) connects the positive of a single lithium battery to the negative of another single lithium battery. The lithium iron phosphate battery pack further comprises an output anode (1014) and an output cathode (1013). The battery pack control circuit comprises a large-current relay (104) electrically connected to the lithium iron phosphate battery pack, a main control circuit (103) electrically connected to the large-current relay, and a battery pack protection circuit (102) electrically connected to the main control circuit. In the lithium iron phosphate battery pack module, single lithium iron phosphate batteries connected in series replace a lead-acid battery pack, achieving the features of being environmentally friendly, small in size, light, long in cycle life, and low in the self-discharge rate, and achieving the ability of large-current discharge.
