Temperature Control Patents (Class 429/62)
  • Patent number: 12381272
    Abstract: A temperature controlled enclosure that includes a temperature control device for controlling the temperature within an internal cavity of the temperature controlled enclosure. The temperature controlled enclosure also includes one or more charging ports for receiving and charging a battery pack. A controller within the temperature controlled enclosure controls the temperature within the internal cavity to a predetermined or desired temperature (e.g., 20° C.). When a battery pack is received in the one or more charging ports, the temperature of the battery pack can be determined. If, for example, the temperature of the battery pack is below 0° C., the battery pack is allowed to warm up inside the temperature controlled enclosure before the battery pack is charged.

  • Patent number: 12358338
    Abstract: Systems and methods for warming a battery and operator cab of an electric vehicle. A second thermal fluid is circulated in a second fluid circuit of a primary system, and is heated by an electric heater before being circulated to a first heat exchanger to heat a first thermal fluid in a fluid thermal tank. The heated first thermal fluid is circulated via a first fluid circuit of the primary system and to the battery, or selectively bypasses the battery and returns to the fluid thermal tank. Occasionally, an external system is coupled to a portion of a third fluid circuit residing in the primary system such that heated third thermal fluid from the external system flows to the first heat exchanger. Partially heated second or third thermal fluid can flow to a second heat exchanger such that the remaining heat entrained therein can heat the operator cab.

  • Patent number: 11964588
    Abstract: A battery provided in a vehicle and configured to supply electric power is cooled down by coolant the heat of which is exchanged with the heat of external air by a radiator. The radiator is provided near the battery and performs heat-exchange between the coolant and the external air taken in through introduction holes provided on a bottom face of the vehicle. Thus, even in a case where the radiator is provided in a vehicle floor portion so that the battery is upsized, it is possible to restrain a coolant pipe from being elongated. This accordingly makes it possible to improve mountability to the vehicle.
