This is a full cell-temperature sensing and high cell voltage accuracy Lithium-ion (Li-ion), lithium iron phosphate (LiFePO4) battery pack (32s) reference design. The design monitors each cell voltage, cell temperature and protects the battery pack to secure safe use. This design uses onboard and offboard daisy-chain communication interface for a cost-effective stacked bus connection. These features make this reference design applicable for high-capacity battery pack applications.
Features
