PROBLEM TO BE SOLVED: To solve a problem of a vehicle for charging a secondary battery with charging control means by photovoltaic power generation means that in a case where it is determined to stop charging operation of the charging control means under a condition that power Wg generated by the photovoltaic power generation means is smaller than power Wc consumed by a charging operation of the charging control means, the control charging means is frequently turned on and off when the vehicle passes through the shadow of a building in an urban district or the like, and sudden repetition change of the power generation amount induces a risk that the voltage of a vehicle power source becomes unstable and the charge control means is early impoverished.SOLUTION: For not Wg>Wc, it is determined whether the vehicle is running. When the vehicle is running, it is awaited until a predetermined time elapses, and then for not Wg>Wc, the operation of the charge control means is stopped.SELECTED DRAWING: Figure 2 |
