Abstract: 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.

The offset voltage command Vst_offset is calculated by adding the offset component V*abc_off of the string voltage obtained from the string voltage command V*abc, the amplitude Vamp of the command voltage calculated using dq shaft voltage command values v*d and v*q, and the margin voltage Vmrg. By determining the on-time ton of the gate signal by using the string voltage command V*abc and the offset voltage command Vst_offset and performing duty control on the gate signal, it is possible to set an offset voltage corresponding to the command voltage, and thus it is possible to suppress an increase in battery loss.
