Abstract

See full text

A battery pack includes cell units in which upper and lower battery cells are connected in series, wherein an output of series-connection and an output of parallel-connection can be switched. The cell units are respectively provided with protection circuit ICs for monitoring the state of the battery cells, and only the protection circuit on the lower cell unit side is provided with a controller 350 including a microcomputer. To adjust the power consumption for the microcomputer only provided in the lower cell unit, the circuit on the upper cell unit side is provided with a current consumption control means including dummy loads. The current consumption control means is operated in conjunction with the start-up of the microcomputer in the controller so as to equalize power consumption on the upper cell unit side and the lower cell unit side.
