Battery Management Development Platform
Atmel’s battery management reference designs show how to get the most out of the AVR battery
management devices. The firmware provides all needed safety measures for a Lithium-ion battery design.
This includes over- and undervoltage protection and protection against excessive charge and discharge
currents. The reference designs also features:
The ATAVRSB200 evaluation kit includes Lithium-ion batteries, a
programmable charger and load, and a USB communication gateway. The SB200 connects to AVR
Studio
parameters can be observed and modified, and the ATAVRSB200 functions are also controlled through
this interface.
