BATTERY PACK TEMPERATURE CONTROL STRUCTURE FOR ELECTRIC VEHICLES

摘要

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.

主权项

1. A battery pack temperature control structure for an electric vehicle, the battery pack temperature control structure comprising:
a first battery module disposed in a first region of an inner space of a battery pack case, the first battery module having a first height; a second battery module disposed in a second region adjacent to the first region in the inner space of the battery pack case, the second battery module having a second height lower than the first height of the first battery module; a temperature control unit having an air blowing port for blowing a temperature control air to the first battery module and the second battery module; and an air duct having a first end connected to the air blowing port of the temperature control unit and a second end having an air blowout opening arranged to blow out the temperature control air from the temperature control unit to a module front upper region of the first battery module, which protrudes in a vehicle upper direction above a top surface of the second battery module, the air blowout opening extending in a vehicle width direction along the module front upper region and blows out the temperature control air toward the first battery module such that the temperature control air from the module front upper region of the first battery module to a rear of the first battery module.
