POWER STORAGE CONTROL DEVICE AND POWER STORAGE CONTROL METHOD

Power generating elements 111 output electromotive force. A path switching unit 112 switches a path for connecting arbitrary power generating elements 111 among the power generating elements 111. A voltage converting unit 130 is a DC-DC converter that converts voltage levels of outputs of some of the power generating elements 111. A path switching control unit 120 controls the path switching unit 112 such that a set of power generating elements 111 where a sum of maximum power point voltages falls within a range of an appropriate charging voltage of a storage element 190 is connected to a short-circuit path 119 and the other power generating elements 111 are connected to a transformation path. A voltage conversion control unit 140 controls a transformation rate of voltage conversion in the voltage converting unit 130 such that a voltage in the transformation path 139 and a voltage in the short-circuit path 119 become equal to each other.
