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.
Claims17
A system for an electric aircraft, the system comprising:
- a battery pack onboard the electric aircraft;
- and
- a circulation loop onboard the electric aircraft, the circulation loop comprising:
- an onboard heat sink thermally coupled to the battery pack;
- an onboard circulation system comprising:
- a distribution manifold fluidly connected to the onboard heat sink;
- a working fluid;
- and
- a pump connected to the distribution manifold and configured to continuously circulate the working fluid through the onboard heat sink during aircraft flight;
- wherein the onboard circulation system does not comprise an onboard compressor;
- and
- a coupling configured to selectively connect the distribution manifold to an offboard cooling system, the offboard cooling system configured to transfer heat from the working fluid to a sub-ambient cooling loop comprising an offboard compressor,
- wherein the circulation loop and the battery pack are configured to cooperatively store more than a threshold percentage of thermal energy generated by the battery pack during aircraft flight.

The system of Claim ii, wherein the pump is arranged between the first and second battery packs.
A system for an electric aircraft, the system comprising:
- a battery pack onboard the electric aircraft;
- and
- a circulation loop onboard the electric aircraft, the circulation loop comprising:
- an onboard heat sink thermally coupled to the battery pack;
- an onboard circulation system comprising:
- a distribution manifold fluidly connected to the onboard heat sink;
- a working fluid;
- and
- a pump connected to the distribution manifold and configured to continuously circulate the working fluid through the onboard heat sink during aircraft flight;
- wherein the onboard circulation system does not comprise an onboard compressor;
- and
- a coupling configured to selectively connect the distribution manifold to an offboard cooling system, the offboard cooling system configured to transfer heat from the working fluid to a sub-ambient cooling loop comprising an offboard compressor,
- wherein a temperature of the battery pack monotonically increases during aircraft flight.
