摘要： In a battery pack where a fan is housed within a case housing a battery stack, the noise generated from turbulence of a medium that is supplied and exhausted between a fan opening of the fan and the battery stack is reduced. The battery pack has a battery stack, a cooling fan installed adjacent to the battery stack and having a fan opening formed in a top surface for taking in cooling air after cooling the battery stack, an upper case for covering the upper part of the battery stack and the cooling fan, and a junction duct for guiding the cooling air after cooling the battery stack to the fan opening. The junction duct is formed from the duct lower unit having an opening formed at a location facing the fan opening and one wall of the upper case in contact with a lower end and periphery of the duct lower unit.

摘要： A power unit including a plurality of series-connected battery modules and a safety circuit.A service plug is inserted from the side of a terminal board of a battery pack, thereby establishing an electrical connection among battery modules. A connector is provided on a back of a terminal cover by way of a projecting section, and a second safety switch is activated by attachment of a terminal cover and insertion of the connector to the terminal board, thereby establishing an electrical connection among the battery modules. Even when the service plug is attached at the time of completion of maintenance without attachment of the terminal cover, the battery modules are still kept in an unconnected state by means of a second switch, and energization, which would otherwise arise with exposed terminals, is prevented.

摘要： A battery pack is constructed with a plurality of battery modules. Each battery module comprises a plurality of prismatic cell cases having short lateral walls and long lateral walls and respectively accommodating elements for electromotive force, these cells being mutually coupled sharing their short lateral walls as partition walls, thereby constituting an integral battery case. Electrode terminals of positive and negative polarities are arranged at longitudinal opposite ends of the integral battery case. Projections and indentations for positioning the plurality of battery modules when coupling them together with their long side faces abutted each other to constitute the battery pack are formed substantially in the center of given cell cases positioned symmetrical with respect to the centerline in the lengthwise direction of the battery module.

摘要： A method for disassembling a battery pack to separate a secondary battery which can be reused, without impairing the performance of a secondary battery, having remaining life which, constitutes the battery pack. A pair of holding plates is brought into contact with binding plates on both ends of a battery pack to compress the battery pack in the stacking direction. The open circuit voltage before and after the compression is measured, and based on an amount of change of the open circuit voltage before and after compression, a battery pack which can be reused is separated.
