Low-Power Design for Battery Management System

This paper designs a Battery Management System (BMS) based on MCU C8051F350 for 4 series Li-ion battery. It implements the functions of battery pack charge and discharge protection, status display, voltage, current and temperature parameter acquisition and accomplishing RS232 communication between MCU and PC. The analysis of the low-power processing is focused on in the circuit design process. Experimental result shows that this design can reduce power consumption of BMS effectively.
