Abstract
An upper limit value setting unit of a control device conducts integration on the change in battery power, and determines whether the integrated value is lower than a preset first threshold value (negative value). When determination is made that the integrated value is lower than the first threshold value, and the battery power difference is lower than the second threshold value (negative value), the upper limit value setting unit sets Vupthat is lower than the general Vupas the upper limit value of the inverter input voltage command.
