| Abstract: | The battery pack can provide enough energy and high-voltage due to the series and parallel connection of multiple single cells.A scheme with a DSP chip named TM320LF2407A to monitor each battery module was proposed.The voltage collection of single battery was completed by OZ890 in each module,and CAN interface circuit and the schematic diagram of electric current acquisition and internal resistance measurement were presented. The scheme can improve the safety and reliability of Li-ion battery pack. |
