Battery power source device wherein a large number of battery modules (9) consisting of a row of a plurality of single cells (7) connected electrically and mechanically in series are arranged parallel to each other and held in a holder casing (10), bus bars (28) being provided that effect electrical connection between the terminals of battery modules (9) at respective end plates (19), (20) positioned at both ends of this holder casing (10) wherein the end plates (19), (20) are constituted of resin plates and the bus bars (28) are fixed to the end plates (19), (20) by insertion molding.
A battery power source device characterized in that a large number of battery modules consisting of a row of a plurality of single cells connected electrically and mechanically in series are arranged parallel to each other and held in a holder casing, bus bars being provided that effect electrical connection between the terminals of battery modules at respective end plates positioned at both ends of said holder casing wherein the end plates are constituted of resin plates and the bus bars are fixed to the end plates by insertion molding.
A battery power source device characterized in that a large number of battery modules, each consisting of a row of a plurality of single cells connected electrically and mechanically in series, are arranged parallel to each other and held in a holder casing, bus bars being provided that effect electrical connection between the terminals of battery modules at respective end plates positioned at both ends of said holder casing wherein the end plates are constitutes of resin plates and the bus bars are fixed to the end plates by insertion molding, leads are connected to the battery modules for measuring voltage across the terminals, fuse mounting elements are molded into one of the end plates for receiving fuses, the leads are embedded in and connected to the fuse mounting elements and the respective leads are collected at a single location on the end plate and extend outside of the end plate to enable an electrical connection of the leads.
A cooling device for a battery power source in which a large number of battery modules are constituted by connecting a plurality of single cells in a row electrically and mechanically in series are arranged parallel to each other and held in a holder casing comprising;
A cooling device for a battery power source in which a large number of battery modules constituted by connecting a plurality of single cells in a row electrically and mechanically in series are arranged parallel to each other and held in a holder casing and air is forcibly made to flow in one direction within said holder casing thereby cooling the large number of battery modules in said holder casing wherein the direction of flow of the air is at a direction at right angles to the longitudinal direction of said battery modules and means for screening are arranged in said holder casing such that the area of said battery modules that is exposed to the air flowing through said holder casing becomes greater from the upstream to the downstream side.
A cooling device for a battery power source comprising a pair of left and right battery power source devices constituted by holding a large number of battery modules consisting of a plurality of single cells connected in a row electrically and mechanically in series arranged horizontally and parallel to each other in a holder casing, respective air supply chambers being formed below said holder casings and wherein air is fed to a lower aperture of the holder casing of the respective battery power source devices through left and right air supply chambers from a pressure-feed fan so that the battery module is cooled by the air current that is discharged from an upper aperture after rising through said holder casings wherein the pressure-feed fan has two blowing ports that supply air in a direction parallel to the surfaces of the end plates into said respective battery power source devices, these blowing ports open in positions close to a respective one end plate of the battery power source devices, the bottom faces of the air supply chambers being formed with a slope whereby the cross-sectional area of the flow path gradually diminishes from the one end plate side towards the other end plate side and means for flow alignment are arranged within said holder casing whereby the flow rate of the air flowing within said holder casing is faster at the upper than at the lower side of said holder casing.
A cooling device for a battery power source comprising a pair of left and right battery power source devices constituted by holding a large number of battery modules consisting of a plurality of single cells connected in a row electrically and mechanically in series arranged horizontally and parallel to each other in a holder casing, respective air supply chambers being formed below said holder casinos and wherein air is fed to a lower aperture of the holder casing of the respective battery power source devices through left and right air supply chambers from a pressure-feed fan so that the battery module is cooled by the air current that is discharged from an upper aperture after rising through said holder casings wherein the pressure-feed fan has two blowing ports that supply air in the direction parallel to the surfaces of the end plates into said respective battery power source devices, these blowing ports opening in positions close to a respective one end plate of the battery power source devices, the bottom faces of the air supply chambers being formed with a slope whereby the cross-sectional area of the flow path gradually diminishes from the one end plate side towards the other end plate side and means for screening are arranged in the holder casing whereby the area of the battery modules that is exposed to the air flowing through said holder casing is greater in an upper part of said holder casing than in a lower part.
