Atmel Corp. announced a smart battery development kit that is based on the company's ATmega406, a highly integrated single-chip smart battery AVR device, targeting Li-ion batteries for laptop computers, medical equipment and portable instrumentation.

The ATAVRSB100 development board is made of a full smart battery implementation and three different support modules to simulate individual cell voltage, total cell stack voltage and charge/discharge current. These modules let developers simulate critical battery situations on request, without the risk and the complexity of using real battery cells. Numerous connectors are available to connect battery cells and to perform debugging and programming of the device, thus allowing developers to easily implement changes to the reference design and fully evaluate these changes before any batteries are connected.

The firmware supplied with the ATAVRSB100 is a framework to develop customized firmware. It supports a full SMBus V1.1 protocol handling, as well as basic algorithms for charge left estimation and battery charging. This enables battery designers to focus on firmware development for the advanced State of Charge (SoC)/ State of Health (SoH) algorithms, and to deliver to the end-users a realistic and accurate indication of the expected battery life. Support for firmware updates through SMBus is also available, allowing installation of improved algorithms for SoC/SoH estimation while the battery is installed in the laptop PC.

"The ATAVRSB100 implementation allows any engineer regardless of prior knowledge of smart batteries to get a jump start in their development," commented Odd Jostein Svendsli, Atmel's marketing manager for battery management solutions. "At the same time engineers can focus on implementing accurate algorithms for their specific battery, knowing that all basic functions are already covered."

The ATAVRSB100 is available for $299.
