Abstract
A heat transfer system regulates the flow of a coolant or heating fluid to the battery of an electric vehicle (EV). Heat transfer systems may be located at charging facilities for charging EVs in an EV fleet. A fleet manager may direct an EV to a particular charging facility to appropriately cool or heat the EV battery during charging; different charging facilities may have different heating or cooling capabilities. The fleet manager may oversee operation of the heat transfer systems, e.g., pre-heating or pre-cooling a heat transfer fluid based on predicted demand.
Claims18
A method for charging an electric vehicle (EV), the method comprising:
- identifying an EV for charging, the EV having an EV battery for receiving and storing electrical charge;
- determining a target temperature for charging the EV battery;
- receiving data describing a plurality of charging facilities;
- selecting a charging facility of the plurality of charging facilities for charging the EV battery based on the target temperature and the received data, the selected charging facility having a heat transfer system for altering a temperature of the EV battery during charging;
- coupling the EV battery to the respective heat transfer system at the selected charging facility;
- and
- regulating flow of a heat transfer fluid from the heat transfer system to the EV,
- wherein the heat transfer fluid at the selected charging facility has a first temperature, a second heat transfer fluid at a second one of the plurality of charging facilities has a second temperature, and the charging facility is selected based on the first and second temperatures.
A method for charging an electric vehicle (EV), the method comprising:
- identifying an EV for charging, the EV having an EV battery for receiving and storing electrical charge;
- determining a target temperature for charging the EV battery;
- receiving data describing a plurality of charging facilities;
- selecting a charging facility of the plurality of charging facilities for charging the EV battery based on the target temperature and the received data, the selected charging facility having a heat transfer system for altering a temperature of the EV battery during charging;
- coupling the EV battery to the heat transfer system at the selected charging facility;
- and
- regulating flow of a heat transfer fluid from the heat transfer system to the EV,
- wherein the selected charging facility comprises a plurality of charging positions, the method further comprising selecting a first charging position of the plurality of charging positions for the EV, the first charging position selected based on a temperature of the heat transfer fluid at the first charging position.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to:
- determine a target temperature for charging a battery of an electric vehicle (EV);
- receive data describing a plurality of charging facilities;
- select the charging facility from the plurality of charging facilities for charging the battery of the EV, the selection based on the target temperature and the received data, the selected charging facility having a heat transfer system to couple to the EV and regulate flow of a heat transfer fluid from the heat transfer system to the battery of the EV;
- and
- cause an instruction to be transmitted to the EV to drive to the selected charging facility and couple to the heat transfer system at the charging facility,
- wherein the heat transfer fluid at the selected charging facility has a first temperature, a second heat transfer fluid at a second one of the plurality of charging facilities has a second temperature, and the charging facility is selected based on the first and second temperatures.
