An electricity storage system comprises a plurality of battery cells in which battery elements are accommodated in angular metal battery cases, wherein the plurality of battery cells are connected together electrically and are disposed in such a manner as to form spaces between the metal battery cells, and wherein the metal battery cell comprises an angular metallic housing on an external surface of which irregularities are formed and a resin portion which is injection molded integrally on the external surface of the metallic housing.

Electricity storage system and metal battery case manufacturing method

In a fuel cell powered electric vehicle having a fuel cell system and an electricity storing device for storing electricity generated by the fuel cell system, the fuel cell system and the electricity storing device stored in a box are fixed to a lower side of a floor of a cabin. A plate is provided to separate the fuel cell system and the electricity storing device in the interior of the box from each other. In addition, through holes are provided in the floor of the cabin for connecting between a refrigerant inlet port and a refrigerant outlet port of the electricity storing device and the cabin.

Capacitor module

An arrangement of a cooling apparatus installed in a vehicle for cooling with an air refrigerant an electricity storing apparatus for storing electricity generated in the vehicle, comprises an inlet port, a discharge duct and a fan. The inlet port let in therefrom the air refrigerant to the electricity storing apparatus. The discharge duct is disposed below a floor surface of a trunk of the vehicle for causing the air refrigerant discharged from the electricity storing apparatus to flow therethrough. The fan is situated in the discharge duct for discharging the air refrigerant. The fan is disposed outwardly of an interior material provided on a side of the trunk of the vehicle. The arrangement of a cooling apparatus can prevent the operating noise of a fan from entering a passenger compartment and which can facilitate the installation of luggage in a trunk.

Arrangement of cooling apparatus

A connecting bus baris formed from a negative opposing sectionwhich is smaller in thickness than a closed end of a bottomed cylinder, partially has a negative weld plate sectionto be welded to the closed end of a bottomed cylinder, and opposes the closed end of the bottomed cylinder; a positive opposing sectionwhich is smaller in thickness than a seal plate, partially has a positive weld plate sectionto be welded to the seal plate, and opposes the seal plates; and the coupling sectionfor connecting together the negative opposing sectionand the positive opposing section. The connecting bus baris formed such that the connecting bus bar, which excludes the negative weld plate sectionand the positive weld plate section, becomes lower in thickness than a thinner one of the closed end of the bottomed cylinderand the seal plate

Connecting structure for electric cells

An accumulating element module includes a plurality of accumulating elements, each having a positive pole terminal and a negative pole terminal at one end. The accumulating elements are connected together at their other ends by an insulating connecting member made of a synthetic rubber. The insulating connecting member includes a plurality of caps and connectors. A deformation-resistant, band-shaped, temperature sensing member having a plurality of excessively raised temperature detectors is inserted through the caps.

Accumulating element module

An electric vehicle in which driving force of a motor driven by batteries is transmitted through a reduction device and a differential to front wheels. The motor and the reduction device are disposed at portions of a vehicle body rearwardly of the differential and hence, a portion of the vehicle body in front of the differential is enlarged and can effectively function as a crushable zone upon a frontal collision of a vehicle. Moreover, the motor and the reduction device which are heavy components are disposed near a central portion of the vehicle body, leading to a mid-ship layout. This conrtibutes to an enhancement in motional property of the vehicle.

Electric vehicle

A battery charging control unit which controls electric power and supplies it to a battery via a charger. The battery charging control unit includes: a charging capacity insufficiency detection unit, a charging capacity restoring determination unit, and a supplemental charging unit. The charging capacity insufficiency detection unit detects an insufficiency in charging capacity of the battery based on the previous charging condition of the battery. The charging capacity restoring determination unit determines if the insufficiency in charging capacity of the battery will be restored by carrying out a supplemental charging process on the battery. The supplemental charging unit carries out the supplemental charging process for the battery if the charging capacity insufficiency detection unit detects the insufficiency in charging capacity of the battery and the charging capacity restoring determination unit determines that the insufficiency in charging capacity of the battery will be restored by the supplemental charging process.

Battery charging control unit and method for controlling battery charging

A charging element device comprising columnar charging element modules arranged by serially connecting cylindrical cells via an insulating ring, the module having a terminal at opposite ends thereof; charging element module groups arranged by laterally aligning the modules in parallel; a built-up construction of the modules arranged by building-up the modules groups in several stages; bus bar plates disposed at the opposite ends of the built-up construction and fitted to the terminals; bus bars disposed outside the bus bar plate and serially connecting the terminals; a housing in which cooling air flows and the built-up construction is contained; and mounting plates having a securing ring for holding and securing the insulating ring, the mounting plate being provided below the lowermost modules group, above the uppermost modules group, and between the intermediate modules groups. The mounting plates are integrally bound so as to hold and secure the insulating ring by the securing ribs, a restriction arrangement for rotation of the insulating ring is provided to the insulating ring and the securing rib.

Rechargeable cell support device with insulating rings

A battery box is detachably supported below a floor panel at a central portion of an electric vehicle. Batteries are mounted in a rear portion of the battery box, and a control unit and a PDU are mounted in a front portion of the battery box. As a result, the positions of the control unit and the PDU are lowered, which can contribute to the lowering of the center of gravity of a vehicle, and power lines extending from the batteries via the control unit and the PDU to a road wheel driving motor can be disposed at shortest distances, whereby the lengths of the power lines can be suppressed to the minimum.

Electric vehicle with battery box arrangement

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.

Battery assembly with temperature control mechanism

An electric vehicle includes a wet type secondary battery wherein a battery housing is provided with electrode plates being operatively positioned within the battery housing. Connector terminals are operatively connected to respective electrode plates. The electrode plates are disposed in a horizontal plane when the battery housing is mounted relative to electric vehicle. A step floor is provided on the electric vehicle and operatively positioned relative to a lower portion of the electric vehicle wherein the battery housing is disposed below the step floor. A charging station is provided for charging the battery.
