Claims21
An electric aircraft comprising:
- a battery pack comprising:
- a first cell and a second cell;
- a plurality of cold plates, a cold plate being thermally connected to each of the first and second cells, each cold plate defining a first and second end;
- and
- thermal insulation interleaved between the first and second cells;
- and
- a circulation loop comprising:
- a pump comprising a pump inlet and a pump outlet;
- and
- a distribution manifold connecting:
- the pump outlet to an end of a cold plate, and
- an end of a cold plate to the pump inlet.
