Abstract
The battery thermal management system includes a battery pack, a circulation subsystem, and a heat exchanger. The system can optionally include a cooling system, a reservoir, a de-ionization filter, a battery charger, and a controller.
Claims20
A method for operation of an electric aircraft, including a battery pack and an onboard circulation system for circulating a working fluid to cool the battery pack, the method comprising:
- while the electric aircraft is connected to an offboard circulation system, adjusting a temperature of the battery pack to or below a takeoff temperature threshold by controlling circulation or temperature of the working fluid through the offboard circulation system and through the onboard circulation system;
- after adjusting the battery pack to or below the takeoff temperature threshold, disconnecting the electric aircraft from the offboard circulation system;
- and
- controlling circulation or temperature of the working fluid through the onboard circulation system and not the offboard circulation system to adjust the battery pack temperature while the electric aircraft is disconnected from the offboard circulation system.

A thermal management system, comprising:
- an electric aircraft including a battery pack and an onboard circulation system for circulating a working fluid to cool the battery pack;
- an offboard circulation system;
- and
- one or more controllers including machine-readable instructions to perform operations, the operations comprising:
- while the electric aircraft is connected to an offboard circulation system, adjusting a temperature of the battery pack to or below a takeoff temperature threshold by controlling circulation or temperature of the working fluid through the offboard circulation system and through the onboard circulation system;
- after adjusting the battery pack to or below the takeoff temperature threshold, disconnecting the electric aircraft from the offboard circulation system;
- and
- controlling circulation or temperature of the working fluid through the onboard circulation system and not the offboard circulation system to adjust the battery pack temperature while the electric aircraft is disconnected from the offboard circulation system.
