摘要： The battery string is configured so that a plurality of battery circuit modules can be connected in series. The drive circuit SU5 from the drive circuit SU0 of the battery circuit module transmits a gate signal for ON/OFF of the switch to the downstream drive circuit SU while delaying the gate signal by a predetermined delay time Td. When a particular battery circuit module (drive circuit SU4 in FIG. 4) is passed through, the delay time is switched from the delay time Td to the delay time Tds. The delay time Tds is longer than the delay time Td. As a result, the period of the gate signal, which is the “delay time×the number of battery circuit modules to be operated”, can be suppressed from becoming short (the increase in frequency can be suppressed), and an increase in loss can be suppressed.
