Thermal Management System for Fast Charge Battery Electric Vehicle
First Claim
1. An electric vehicle thermal management system comprising:
- a traction battery assembly having a thermal plate;
a coolant circuit, including a chiller, arranged with the thermal plate to distribute coolant thereto;
an exchanger arranged with the coolant circuit for thermal, but not fluid, communication therebetween;
a charge port assembly in fluid communication with the exchanger and configured to receive coolant from an external source; and
a control system including a control line configured to communicate with the external source, to monitor conditions of the traction battery assembly, chiller, and external source, and to direct operation of the external source based on the conditions.

Abstract
An electric vehicle thermal management system may include a traction battery assembly, a coolant circuit, an exchanger, a charge port assembly, and a control system. The traction battery assembly may include a thermal plate. The coolant circuit may include a chiller and may be arranged with the thermal plate to distribute coolant thereto. The exchanger may be arranged with the coolant circuit for thermal, but not fluid, communication therebetween. The charge port assembly may be in fluid communication with the exchanger and may be configured to receive coolant from an external source. The control system may include a control line configured to communicate with the external source, to monitor conditions of the traction battery assembly, chiller, and external source, and to direct operation of the external source based on the conditions.

9. An electric vehicle comprising:
-
a traction battery assembly including a thermal plate; a chiller in fluid communication with the thermal plate via a coolant circuit channel; a charge port assembly defining two coolant channels each configured for fluid communication with an external charge station; a heat exchanger arranged with the coolant circuit channel for thermal communication therebetween; sensors to measure a temperature of a coolant of the chiller, the exchanger, and the thermal plate; and a battery control module to receive the measured temperatures and direct operation of the charge station based on whether the measured temperatures fall within respective predetermined temperature ranges. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A thermal management method for an electric vehicle comprising:
in response to receiving a predetermined combination of temperature values of coolant for each of a vehicle chiller, a vehicle exchanger, and a thermal plate of a vehicle traction battery assembly, outputting via a controller a control strategy to direct operation of a charge station remote from the vehicle to selectively output coolant to the vehicle exchanger without the coolant entering the thermal plate. - View Dependent Claims (17, 18, 19, 20)
