Abstract: A battery cell cooling assembly for a vehicle comprising a cooling vessel having a coolant flow path between an inlet and outlet, cell apertures exterior to the flow path, a first directional directing coolant from the inlet into laterally spaced first sub-channels, a second directional receiving coolant from the first sub-channels and directing it into laterally spaced second sub-channels, the first sub-channels extending transversely between the cell apertures and aligned longitudinally between first aperture ends and second aperture ends of the cell apertures, the second sub-channels extending transversely between the cell apertures and aligned longitudinally between the first sub-channels and the second aperture ends, wherein the first sub-channels provide a first thermal pass by each of the plurality of cell apertures and the second sub-channels provide a second thermal pass by each of the same plurality of cell apertures for temperature control of the cells during operation.

Abstract: An electric motor that can be used in driving a compressor and that incorporates a magnetic gear. The motor has high and low speed stators mounted within a motor casing side-by-side that drive coaxial low and high speed rotors also mounted within the motor casing for rotation and within the high and low speed stators. The high and low speed stators produce rotating magnetic fields that rotate in opposite directions to drive the rotors under application of a multiphase alternating current. The low speed rotor has a set of ferrous pieces, rotating with the low speed rotor and mounted thereon between the high speed rotor and the high speed stator. The ferrous pieces produce a magnetic gearing effect to drive the high speed rotor at a higher speed than the low speed rotor and in an opposite direction to the low speed rotor.
