Abstract :
A six Li-ion cell string is used as the core of a modular battery for a total 100 Wh@C/2 capacity and a Wh efficiency of about 90%. Integrated charge/discharge prototype electronics is based on COTS components which allows us to obtain an efficiency greater than 90% and negligible mass and volume. Electronics can be managed by an integrated microcontroller which can by reprogrammed by the on-board computer. Battery management is foreseen at three levels: local battery module, power conditioning unit and on-board computer.
