Abstract: An electric vehicle (EV) charging and cooling system is described that supplies electric power to charge an EV while simultaneously providing coolant to cool the charging components of the EV during the charging process. For example, the system includes a charging device that provides electrical power for charging a battery of the EV. The system also includes a coolant device that transfers coolant to the EV during charging for cooling the battery of the EV. The system also withdraws the coolant from the EV that has been used, and heated to a temperature that may not be suitable for cooling as a result of absorbing heat from the charging components. The system can cool the used coolant back to the cooled temperature to recirculate to the EV throughout a direct current (DC) fast charging process, which provides thermal stability and mitigates damage to the EV from overheating.
