In the high voltage electrical packaging box, an interposing member which is formed using an expandable resin, is disposed between the box body and the high voltage electric part. Air may be pass through the inside of the box body so as to cool down the high voltage electric part placed in the box body.

Abstract: A charging element device comprises a positive electrode terminal and a negative electrode terminal which are located at one end of a cylindrical battery case having a positive electrode and a negative electrode equipped therein and which are respectively connected to the positive electrode and the negative electrode, with an electrolyte solution charging opening being formed at the other end of the battery case. The electrolyte solution charging opening is sealed by a plug having a safety valve, and the safety plug reduces an inner pressure of the battery case when the inner pressure is not less than a predetermined pressure.

Abstract: A small battery box, in which arrangement of cells can be easily changed, for suppressing nonuniformity in temperature distribution between the cells. The box has a container having upper, lower, front, rear, and side portions which can be disassembled; a battery holder having members which are detachably connected in a manner such that central axes of the cells are parallel to a direction along which the side portions face each other and the cells are arranged in a zig-zag matrix form; a shielding member, near a coolant supply opening in the front portion, for changing the flow direction of the coolant and for preventing the coolant from directly blowing onto the cells; and a control member, near a coolant discharge opening in the rear portion, for changing the coolant flow direction in a manner such that the coolant flows towards the rear side of each cell near the discharge opening.

Abstract: A structure for cooling one or more units built in a hybrid vehicle, where the structure is simple and can be inexpensively realized, and has a high cooling efficiency. The hybrid vehicle has an internal combustion engine and high-voltage units which include a motor which assists driving power of the engine and also functions as a power generator, a high-voltage storage battery for storing generated power, and a high-voltage controller provided between the motor and the storage battery. At least one of the high-voltage units is provided in an air intake passage for the engine, through which an air passes while cooling said at least one of the high-voltage units.

Abstract: A seal member comprises a resilient material and allows a pass-through member 105 to pass through an opening 106 while closing a gap formed between the pass-through member 105 and the opening 106, and the periphery of the opening 106 is made to constitute a wavy and annular sealing portion 117 which undulates in a direction in which the pass-through member 105 passes through the opening 106.

Abstract: A structure for mounting a box for containing high-voltage electrical equipment on a vehicle, so as to suppress increase in the number of parts, the weight of the vehicle, and the manufacturing cost by effectively using existing structural members of the vehicle body. The structure includes a frame member which is attached to the box and which extends to the rear side of the vehicle, and the frame member is combined with side frames which are structural members of the body of the vehicle. Typically, The frame member consists of two frame members which are respectively attached to the side frames at the right and left sides, and the structure further comprises a cross beam for coupling the frame members with each other, wherein the cross beam extends in the width direction of the vehicle.

Abstract: The present invention aims to cool high tension electrical equipment efficiently with a small, lightweight device. The high tension electrical equipment cooling structure is provided for cooling batteries which supply electricity to the operating motor via an inverter, and the inverter using cooling air, and comprises an equipment box for guiding cooling air introduced from a cooling air inlet port into a cooling air outlet port, and a fan for introducing cooling air from the cooling air inlet port. A shutter that consists of an elastic material is disposed inside the intake duct. The shutter closes off the cooling air flow path, and when negative pressure is generated downstream of the shutter due to the operation of the fan, the shutter undergoes elastic deformation, and as a result, the cooling air flow path is opened.

Abstract: A battery assembly has a temperature control mechanism for effecting cooling or heating unit batteries for operation in a desired temperature range. First heat-exchange planar members of respective heat-transfer plates are sandwiched between the unit batteries that are arranged in an array, and second heat-exchange planar members thereof are held against transverse narrow side walls of the unit batteries. The unit batteries and the heat-transfer plates are securely fastened together by holder plates. Heat produced when the unit batteries are in operation is transferred through the first and second heat-exchange planar members of the heat-transfer plates and dissipated into an appropriate cooling medium, such as atmospheric air or another cooling fluid, through a heat-exchange.
