Introduction
B
attery Management Systems (BMS) connect
to high energy battery packs and manage the
charging and discharging of the pack. They also
monitor essential safety factors, including temperature,
state of charge, and the pack's state of health. Providing
additional application protection, the BMS can connect the
battery and disconnect it from the load or charging source,
as required.
This application note provides an overview of the key
features of battery monitoring Integrated Circuits (ICs)
typically specified in BMS. It includes background
information on battery-cell chemistries related to the
requirements for communications in high voltage BMS.
An application example will explain the technology
benefits that Bourns® transformers deliver to meet these
specifications.
