PROBLEM TO BE SOLVED: To allow for charging from a high voltage main power storage device to a low voltage sub-power storage device, when limitation of Win is applied to the high voltage main power storage device, in a charge controller of vehicle.SOLUTION: A charge controller of vehicle including a main power storage device MB and a sub-power storage device SB for an auxiliary machine connected with the MB via a DCDC converter allows charging from the MB to SB (STEP16, STEP18), by releasing auxiliary machine power reduction control in the SB, when the Win of the MB is limited and the SB can be charged (STEP12, STEP14), and prohibits charging from the MB to SB (STEP20, STEP22), while continuing auxiliary machine power reduction control in the SB, when the Win of the MB is not limited, or the SB cannot be charged.

    【課題】車両の充電制御装置において、高電圧メイン蓄電装置にWinの制限が加えられるときに、高電圧メイン蓄電装置から低電圧サブ蓄電装置への充電を可能とすることである。【解決手段】メイン蓄電装置であるMBと、DCDCコンバータを介してMBに接続される補機用のサブ蓄電装置であるSBとを備える車両の充電制御装置は、MBのWinが制限されていて、かつSBが充電可能であるときは(STEP12,STEP14)、SBにおける補機電力削減制御を解除して、MBからSBへの充電を許可し(STEP16,STEP18)、MBのWinが制限されていないか、またはSBが充電可能でないときはSBにおける補機電力削減制御を継続して、MBからSBへの充電を禁止する(STEP20,STEP22)。【選択図】図2
