Fast charging cooling loop heat exchanger
A charging system includes an electric vehicle having a battery coolant circuit including a charging heat exchanger and a battery as well as a charging station including a charging coolant and a cooling heat exchanger for cooling the charging coolant. The charging coolant is selectively placed in fluid communication and heat exchange communication with the charging heat exchanger of the electric vehicle. The charging heat exchanger is disposed on a charging coolant flow path formed in the electric vehicle that extends from an inlet port configured for coupling to an inlet fitting of the charging station to an outlet port configured for coupling to an outlet fitting of the charging station.
1. An electric vehicle comprising:
a battery coolant circuit including a battery and a charging heat exchanger, the battery coolant circuit circulated by a battery coolant in fluid communication and heat exchange communication with each of the battery and the charging heat exchanger, the charging heat exchanger configured for selective fluid communication and heat exchange communication with a charging coolant originating external to the electric vehicle, wherein the charging coolant is passed through a charging coolant flow path formed within the electric vehicle and including the charging heat exchanger, wherein the charging coolant flow path extends from an inlet port to an outlet port of the electric vehicle, and wherein the charging coolant flow path includes an inlet flow path connected to the inlet port and an outlet flow path connected to the outlet port.
2. The electric vehicle of claim 1 , wherein each of the inlet port and the outlet port is disposed at an exterior of the electric vehicle.
3. The electric vehicle of claim 1 , wherein the inlet port is configured for forming a fluid tight connection with an inlet fitting associated with a charging station while the outlet port is configured for forming a fluid tight connection with an outlet fitting associated with the charging station.
4. The electric vehicle of claim 1 , wherein the charging coolant originates from a charging station configured to charge the battery using an independently provided power source.
5. The electric vehicle of claim 1 , wherein the charging heat exchanger is also configured for selective fluid communication with one of a flow of air or a flow of the flushing liquid originating external to the electric vehicle.
6. The electric vehicle of claim 1 , further comprising a refrigerant circuit circulated by a refrigerant, the refrigerant circuit including a chiller in fluid communication and heat exchange communication with each of the refrigerant of the refrigerant circuit and the first coolant of the battery coolant circuit.
7. The electric vehicle of claim 6 , wherein the refrigerant circuit further includes an evaporator for conditioning air to be supplied to a passenger compartment of the electric vehicle.
