Abstract
A charge and discharge control unit (41) sets an upper-limit charge and discharge electric power as an upper limit of electric power during charging and discharging of a electric storage device (11) based on temperature of the electric storage device (11) measured by a temperature measuring unit (21) and a state of charge of the electric storage device (11) specified by a charge state specifying unit (23). In the case where the operation state determined by an operation state determining unit (35) is a low-limit operation state, the charge and discharge control unit (41) sets the upper-limit charge and discharge electric power to be larger than that in the case where the operation state determined by the operation state determining unit (35) is a high-limit operation state.
