Application: Thermal management system for electric vehicles (Patent ID: US20230415593A1)

The patent filed by Hyundai Motor Co. describes a thermal management system for electric vehicles that includes a coolant circulation line in a charging station, a connector linking the circulation line to the vehicle's cooling system, and a controller that regulates the temperature of the coolant based on the battery's cooling or heating needs during rapid charging. The system can activate cooling or heating modes in the vehicle by exchanging heat between the coolant and the cooling system.

The claims detail the components and functions of the thermal management system, including separate cooling circuits for power electronic components and the battery, an air conditioning system for refrigerant circulation, and a chiller for heat exchange. The controller can adjust the coolant temperature based on the battery's temperature, the vehicle's ambient temperature, and can supercool or overheat the coolant before injecting it into the vehicle. Additionally, the system includes low and high-temperature tanks for storing supercooled and overheated coolant, with the controller setting the coolant temperature according to the ambient temperature.
