Abstract
An electric motor vehicle cooling system is described that cycles liquid coolant from a charging station into the vehicle and back, to cool the batteries during charging. The liquid coolant is pumped by a pump in the charging station through channels in the cable that is plugged into the vehicle. The cable has an adaptor with ports to allow the coolant to exit the charging station, travel into the vehicle to cool the batteries, and return back into the charging station from the vehicle. The charging station cools the coolant using a chiller. This cooling system allows the charging station to perform most of the work of cooling the vehicle batteries, without overly taxing the vehicle's on-board thermal management systems.
Claims20
An electric motor vehicle charging station, comprising:
- a base, the base including a source of electricity and a pump;
- a cable, the cable being connected to the base at a first end of the cable, the cable including
- at least one electrical wire that carries electrical current from the source of electricity, and
- a hose including an outlet channel and an inlet channel;
- an adaptor, the adaptor being connected to a second end of the cable and being configured to interface with a receptor on an electric motor vehicle;
- and
- liquid coolant;
- wherein the adaptor further includes
- at least one electrical charging connector, connected to the at least one electrical wire in the cable;
- a liquid coolant outlet port, connected to the outlet channel of the hose and configured to allow the liquid coolant to exit the charging station, and
- a liquid coolant inlet port;
- connected to the inlet channel of the hose and configured to received liquid coolant into the charging station;
- and wherein the charging station is configured to move the liquid coolant with the pump in a cycle from the base, through the outlet channel of the hose in the cable, out of the liquid coolant outlet port on the adaptor, into the electric motor vehicle, into the liquid coolant inlet port on the adaptor, through the inlet channel of the hose in the cable, and back into the base.
An electric motor vehicle comprising:
- a battery;
- a battery temperature management system;
- and
- a receptor, the receptor being configured to interface with an adaptor of an electric motor vehicle charging station;
- wherein the receptor includes
- a liquid coolant inlet port, the liquid coolant inlet port being configured to receive a liquid coolant into the electric motor vehicle, and
- a liquid coolant outlet port, the liquid coolant outlet port being configured to allow the liquid coolant to exit the electric motor vehicle;
- and wherein the liquid coolant interfaces with the battery temperature management system, in such a manner as to cool the battery when the electric motor vehicle is charging at an electric motor vehicle charging station.
An electric motor vehicle cooling system, comprising:
- an electric motor vehicle charging station;
- an electric motor vehicle including a battery;
- and
- a liquid coolant;
- wherein the charging station is in fluidic communication with the vehicle, such that the charging station and the vehicle collectively form a battery cooling loop through which the liquid coolant is cycled.
