Abstract
A vehicle battery charging system includes a battery charger for charging a battery module of a vehicle. A first coolant circuit conveys a first cooling fluid therethrough. The first coolant circuit includes a chiller unit separate from the vehicle. The chiller unit and the first cooling fluid exchange heat therebetween. A second coolant circuit conveys a second cooling fluid therethrough. The second coolant circuit includes a battery module. The battery module and the second cooling fluid exchange heat therebetween. A heat exchanger exchanges heat between the first cooling fluid and the second cooling fluid.
Claims18
A vehicle, comprising:
- a battery module;
- a first coolant circuit conveying a first cooling fluid therethrough, wherein the first coolant circuit includes a first electrical cooling delivery line and a first electrical cooling return line;
- a second coolant circuit conveying a second cooling fluid therethrough, the second coolant circuit configured for heat transfer communication with the battery module, the battery module and the second cooling fluid exchanging heat therebetween, wherein the second coolant circuit is in fluid communication with a second electrical cooling delivery line and a second electrical cooling return line;
- and
- a heat exchanger exchanging heat between the first cooling fluid and the second cooling fluid, wherein the first coolant circuit includes a first cooling connector configured to cooperate with a second cooling connector to open and close the first coolant circuit, wherein the battery module of the vehicle is electrically coupled to a charging connector by an electrical line, wherein at least a portion of the electrical line is in heat transfer communication with the second coolant circuit.
