Battery Management System for Measuring Remaining Charges in a Battery Packet with Multi-Cells
First Claim
1. A battery management system for measuring remaining charges in a battery packet with multi-cells comprising:
- a battery packet having multi-cells for a portable device, electric property and non-electric property measuring modules, a slave communication protocol controller, and a battery protective integrated circuit, wherein said electric property and non-electric property measuring modules are connected in between said multi-cells and the slave communication protocol controller to provide data of electric property and non-electric property of every cell in said multi-cells and said data are transferred to said slave communication protocol controller, further, said slave communication protocol controller provided to receive first control parameters and second control parameters from the portable device so as to manage said multi-cells;
a charge gauge module and a master communication protocol controller installed in the portable device, said master communication protocol controller inquiring said data of electric property and non electric property of every cell and calculating remaining charging of each cell of said multi-cells and transferring said first parameters and said second parameters to said slave communication protocol controller.

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.
