This reference design is a central controller for a high-voltage Lithium-ion (Li-ion), lithium iron phosphate (LiFePO4) battery rack. This design provides driving circuits for high-voltage relay, communication interfaces, (including RS-485, controller area network (CAN), daisy chain, and Ethernet), an expandable interface to humidity sensor, high-voltage analog-to-digital converter (ADC), and current sensor. This design uses a high-performance microcontroller to develop and test applications. These features make this reference design applicable for a central controller of high-capacity battery rack applications.
