Abstract

The paper presents a new battery management system for a lithium ion battery pack for more efficient operation and sturdy. The new system contains an embedded microcontroller to track the energy content of cell battery, optimize the output current, and to provide extensive feedback of all the measurements taken. This system sends all data to a telemetry system so that the data can be relayed to a laptop via wireless signal. Two unique advance features of the BMS are its ability to optimize the battery pack energy and also to provide cell equalization. Since the BMS is used in an electric vehicle, very low power consumption is essential
