PROBLEM TO BE SOLVED: To provide an equalization device which can quickly and accurately perform equalization with a simple structure.SOLUTION: An A/D converter in an equalization block detects voltages across unit batteries Cto Crespectively and transmits them to an MCU. The MCU has smallest voltage of the voltages detected by the respective equalization blocks as a reference voltage, divides magnitude of the voltages across the respective unit batteries Cto Cinto "discharge long," "discharge normal," "discharge short," and "no discharge" in accordance with a difference between the reference voltage and the voltages across the unit batteries Cto C, and performs on-off control of a switch so that a unit battery Cof "no discharge" to be the nearest division to the reference voltage is not discharged, and the longer the other unit batteries Cto C, Care charged the farther they are from the reference voltage. |
