  • Patent number: 10109894
    Abstract: In a battery pack structure for electric vehicles that a battery module, a junction box, and a battery controller for battery management are mounted in a battery-pack-case internal space, clearances, ensured when the battery module is mounted in the case internal space, are configured as temperature-adjustment air passages through which temperature-adjusting air flows. The junction box and the battery controller are arranged at positions spaced apart from each other and facing one straight passage part of the temperature-adjustment air passages. Furthermore, a weak-electric harness, via which the junction box and the battery controller are connected to each other, is wired along the straight passage part, thus ensuring smooth flow of temperature-adjusting air, while improving both the harness-wiring workability and the harness durability.

  • Patent number: 9742043
    Abstract: A battery pack temperature control structure is provided for an electric vehicle, and basically includes first and second battery modules, a temperature control unit and an air duct. The first and second battery modules are disposed inside a battery pack case. The second battery module has a lower height than the first battery module. The temperature control unit has an air blowing port for blowing a temperature control air to the first and second battery modules. The air duct is connected to the air blowing port of the temperature control unit, and has an air blowout opening arranged to blow out the temperature control air to a front of the first battery module at a location above the top of the second battery module. The air blowout opening-extends in a vehicle width direction and blows out the temperature control air toward the first battery module.

  • Patent number: 9564664
    Abstract: A battery pack temperature control structure is provided for an electric vehicle, and basically includes a battery module, a heavy-current disconnecting switch and a temperature control unit. The battery module is mounted in an inner space of the battery pack case. The heavy-current disconnecting switch disconnects, by a manual operation, a battery high-power circuit in the battery module. The temperature control unit is mounted in the inner space of the battery pack case for producing a temperature-controlled air to be blown to the battery module. The heavy-current disconnecting switch is disposed in an upper space position within the inner space of the battery pack case. The temperature control unit is disposed in a space position that is lower than the heavy-current disconnecting switch and that overlaps with the heavy-current disconnecting switch in the vehicle vertical direction.

  • Patent number: 9444082
    Abstract: An object of the present invention is to secure both of vehicle body floor upper space and battery mounting space, in setting of a mounting position of a high-power cut-off switch to a battery pack case. Battery pack case 1 having battery modules 2 and SD switch 4 that cuts off battery high-power circuit by manual operation is arranged in a lower position of vehicle body floor 100. In this battery pack structure for electric vehicle, an inside space of the battery pack case 1 is divided into two areas in a vehicle front-and-rear direction, and one of the two areas is defined as a battery module mounting area 7. SD switch 4 is provided in an upper surface position of the case that covers an electrical component mounting area 8, which is the other area, located on a vehicle front side with respect to battery module mounting area 7.
