A hybrid electric vehicle 1 has a battery state detecting unit for detecting a temperature and SOC of a battery pack, a storage unit for storing a first target SOC calculation map in which a battery temperature and a target SOC which enables regenerative power generation at that battery temperature are associated with each other, and a second target SOC calculation map in which a battery temperature and a target SOC which enables startup of an internal combustion engine at that battery temperature are associated with each other, and a charging/discharging control unit for acquiring a target SOC which corresponds to the detected battery temperature based on the first target SOC calculation map or the second target SOC calculation map to control charging/discharging so that the detected SOC matches the acquired target SOC.
