INTEGRATED CELL VOLTAGE MEASUREMENT AND EQUALIZATION SYSTEM FOR SERIES-CONNECTED BATTERIES AND METHOD FOR OPERATING SAME

摘要

A battery pack management system comprises a power supply adapted to be connected to a battery pack. The battery pack includes a plurality of cells, where each cell is interconnected in a series arrangement to other cells in the battery pack. Each cell has a cell charge characteristic and a voltage potential characteristic. An electronic control unit (ECU) measures the voltage potential characteristic of each cell. An equalizing circuit (EQU) equalizes the voltage of each cell individually relative to the other cell voltages in the battery pack. A common harness connects the plurality of cells both to the electronic control unit (ECU) and to the equalizing circuit (EQU).
