Abstract
A battery management system for measuring remaining charges in a battery packet with multi-cells is disclosed. The battery comprises electric property and non-electric property measuring modules, multi-cells, a slave communication protocol controller, and a battery protective circuit. The portable device comprises an embedded controller and a charge gauge module and a master communication protocol controller. The parameters demanded for calculating the remaining charges of the multi-cells are measured by the electric property and non-electric property measurement modules and transferred through the SMBus interface to the embedded controller and the charge gauge module. Therefore, the battery management system can manage the remaining charges of every cell in the multi-cells without a microprocessor in the battery packet.
