Application: Thermal management system for electric vehicles (Patent ID: US20230415593A1)
The patent filed by Kia Corp 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 manages the temperature of the coolant based on the battery's cooling or heating needs during 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 different cooling circuits for power electronic components and the battery, an air conditioning system with a chiller for heat exchange, and the controller's ability to adjust coolant temperature based on battery temperature and ambient conditions. The system can supercool or overheat the coolant before injecting it into the vehicle, and it includes low-temperature and high-temperature tanks for storage. Additionally, the controller can activate cooling or heating modes during driving based on the battery's temperature after charging.
