An in-vehicle power supply system includes multiple power pods each holding multiple power cells, and a mechanical transport system to exchange power cells. Each power cell includes a controller and a power converter with a coil wound around a through hole. Each power pod includes a controller and a power converter with a magnetic core having posts that pass through the through holes of the power cells. Multiple parts of the magnetic core can be opened to allow power cell exchange. The power cells held by each power pod are magnetically parallel to each other and coupled to the power pod by magnetic field coupling. Also disclosed is an electric motor incorporating such power cells as a part of its stator, with coils of the power cells disposed around parts of the stator's magnetic core to function as coils of the stator.
