  • Publication number: 20080315736
    Abstract: In a cabinet, an inverter housing is mounted on an inverter housing mounting surface. Heat-exchanger-side pipe connection ports are disposed so as to extend through the inverter housing mounting surface toward a heat exchanger for use as an air-cooling device. Further, controller-mounting-side pipe connection ports are disposed so as to extend on a controller mounting side. A refrigerant supply line is a refrigerant passage through which a refrigerant is cyclically fed from the refrigerant cooling device. One end of the refrigerant supply line is connected to the heat-exchanger-side pipe connection ports or the controller-mounting-side pipe connection ports, while the other end is connected to the refrigerant cooling device that penetrates an appropriate part of a wall of the cabinet and is situated in a proper position outside the cabinet.

  • Publication number: 20080213674
    Abstract: The present invention provides a secondary battery using a liquid electrolyte excellent in storage characteristics. The secondary battery includes a cathode, an anode, and a liquid electrolyte, where the cathode and the anode contain at least one mutual active material. This symmetrical electrode configuration, that the at least one active material for the cathode and the anode is mutual, enables equalization of an electrode electric potential difference before charge or after discharge; and thus electrolyte degradation is efficiently restrained to improve storage characteristics.
