Abstract: Example embodiments of rapid charging power supply systems are disclosed herein. One example rapid charging power supply system comprises: a stationary rapid charger (11); a power supply switch (11m) for switching and supplying DC power from the stationary rapid charger (11) to either a first charging circuit (20A) for supplying the DC power to a first electric moving vehicle (50) or a second charging circuit (20B) for supplying the DC power to a second electric moving body (53); a stationary electric storage unit (15) capable of storing DC power from the first charging circuit (20A) and used for being directly supplied to at least the first electric moving body (50); and a power feeding controller (12) for stopping power supply to the stationary electric storage unit (15) when charging an on-vehicle electric storage unit (85) of the first electric moving body (50).

Abstract: Embodiments of the disclosed technology are directed to a rapid charging power supply system capable of rapidly charging an electric moving body, such as a vehicle. Certain example embodiments are directed to a rapid charging power supply system capable of rapidly charging two electric moving bodies with different charging methods at the same time using a single system. For example, a rapid charging power supply system capable of rapid charging, using a single system, both an electric moving body having a rapid-charging control means equipped therein and an electric moving body that does not have a rapid-charging control means equipped therein is provided.

Abstract: An electrically-driven mobile body which can be given a boosting charge with electric power supplied by a single power supply apparatus together with other electrically-driven mobile bodies having different charging conditions and which can cool a charging system thereof without any coolant from the outside, as well as a boosting charge method for an electrically-driven mobile body for the same purpose.

Abstract: A boosting-charge power supply apparatus which supplies electric power for charging a mobile body having a boosting-charge control function includes: a rectifier for supplying DC power; a first power storage for storing DC power from the rectifier and outputting DC power; a charging circuit which sends DC power from the first power storage directly to a vehicle including a second power storage for storing DC power from the first power storage; and a power-supply controller for stopping the rectifier from supplying electric power to the first power storage while the first power storage is supplying electric power to charge the second power storage. Through the controller, DC power supplied from the first power storage becomes suitable for charging of the second power storage on the vehicle side, thereby enabling the same boosting-charge power supply apparatus to supply electric power and give a boosting charge to a different type of vehicle.

Abstract: A boosting-charge power supply apparatus and a boosting-charge power supply method are capable of supplying electric power for boosting charge to a variety of mobile bodies using a single apparatus and supplying high-quality electric power to the mobile bodies.

Abstract: A power generating apparatus and a power generating method capable of reducing a power generating price by generating a power by high head turbines and a generator used in a dam type or conduit type power plant even if the head of water is small. The power generating apparatus comprises first water wheels (2) driven by the flow of water (W1), pumps (3) connected to the first water wheels (2) and pumping up a part of the water (W1), a pressure control valve (7) raising the pressure of the water (W1) discharged from the pumps (3) to a predetermined pressure, a second water wheel (4) installed on the ground and driven by the water (W1) from the pressure control valve (7), and a generator (5) installed on the ground and driven by the second water wheel (4).
