<p>PROBLEM TO BE SOLVED: To strike a balance between suppression of a loss in a vehicular power apparatus and suppression of a shortage in temperature rise of a battery.SOLUTION: If temperature rise-enabled time t1 in which a battery temperature can be raised is equal to or more than temperature rise-requiring time t2 that is required for a temperature-raising device to complete raising a temperature of the battery using power from a sub-DC-DC converter, the sub-DC-DC converter is connected to a temperature adjustment device so as to supply power from the sub-DC-DC converter to the temperature-raising device, raising the temperature of the battery (S150, S160). In contrast, if the temperature rise-enabled time t1 is less than the temperature rise-requiring time t2, a main DC-DC converter is connected to the temperature adjustment device so as to supply power from the main DC-DC converter to the temperature-raising device (S150, S120).</p> |
