|20150255997||SYSTEM OF COMMUNICATION BETWEEN STACKED INTEGRATED CIRCUITS POWERED BY DIFFERENT VOLTAGE SUPPLY LEVELS IN MULTIPLE CELL-STACKED BATTERY PACK - A system of communication between stacked integrated circuits powered by different voltage supply levels in a multiple cell-stacked battery pack is disclosed. The system includes a number of battery cells and a number of integrated circuits. Each integrated circuit includes a battery detecting unit, a data transceiving unit and a power acquiring unit. Since the data transceiving unit transmits signals by toggling voltage level, current flow which causes higher power consumption can be avoided. Meanwhile, the system of communication can therefore be applied to many internal communicating protocols.||09-10-2015|
|20150244193||METHOD OF SEARCHING FOR FULL CHARGE CAPACITY OF STACKED RECHARGEABLE BATTERY CELLS IN RECHARGEABLE BATTERY PACK AND BATTERY MANAGEMENT SYSTEM MADE OF THE SAME - A method of searching for full charge capacity of stacked battery cells in a rechargeable battery pack and a battery management system based on the method are disclosed. The method includes the steps of: predefining an end-of-discharge condition as a ratio of change of open-circuit cell voltage to change of state of charge; providing a full charge capacity for a rechargeable battery pack assembled of several stacked battery cells; charging the rechargeable battery pack until it is fully; discharging the rechargeable battery pack; measuring current values and open-circuit cell voltages periodically; processing coulomb counting based on the measured current values and zeroing a sum of coulomb counting values when a new discharging cycle begins; estimating state of charge during discharging periodically; calculating a running ratio; and updating the full charge capacity by the current sum of the coulomb counting values when the running ratio is equal to or greater than the end-of-discharge condition.||08-27-2015|
