Battery-powered devices that are plugged in most of the time without proper management result in shortened battery life when running on their own power, which can be costly on the customer side and potentially a hazard to the environment. This project proposes a battery cycling algorithm aiming at laptop power system application that could potentially improve battery life for such devices. A proof-of-concept prototype with discrete battery cells was designed to demonstrate the proposed algorithm. DC-DC converters and microcontroller circuits were successfully assembled and tested. Future work is needed to assemble and integrate the battery switching circuit, verify the improvement to battery life, as well as integrate this system into a laptop designed for commercial production.
