Technical Field
The present disclosure relates generally to an assembly for managing the thermal energy level of a traction battery, and more particularly to a packaging portion of the assembly.
Background
An electrically powered vehicle differs from a conventional motor vehicle in that the electrically powered vehicle uses one or more electric machines that are powered by a traction battery to selectively drive. The electric machine may drive an electrically powered vehicle instead of or in addition to the internal combustion engine. Exemplary electrically powered vehicles include Hybrid Electric Vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), Fuel Cell Vehicles (FCVs), and Battery Electric Vehicles (BEVs).
The traction battery is a relatively high voltage battery that selectively powers the electric machine and other electrical loads of the electric vehicle. The traction battery may include an array of batteries each including a plurality of interconnected battery cells that store energy. Traction batteries for electrically powered vehicles typically include a plurality of arrays each having individual battery cells that are periodically recharged to supplement the energy required to power the electric machine. The battery cells may become hot during charging and discharging, as well as during other phases of operation. Operating the battery cell at a particular temperature may improve the capacity and life of the battery cell. Managing the thermal energy level of the traction battery may facilitate efficient operation.

Features of exemplary embodiments may include enclosing a heat exchange module of a thermal management system within or near a cargo compartment and moving air from an area under a vehicle to and from the heat exchange module. Another feature is exchanging thermal energy between the fluid and air at the heat exchange module. Air is drawn into the heat exchange module from an area beneath the vehicle, and air is distributed from the heat exchange module to an area beneath the vehicle.
Having the inlet of the heat exchange module and the outlet of the heat exchange module open to the area under the vehicle reduces the visual impact of the inlet and outlet. Furthermore, the heated air is not discharged into the cargo compartment, which may be objectionable.
The foregoing description is exemplary rather than limiting in nature. Variations and modifications to the disclosed examples may become apparent to those skilled in the art that do not necessarily depart from the essence of this disclosure. Accordingly, the scope of legal protection given to this disclosure can only be determined by studying the following claims.
