Abstract: Multiple chemistry battery systems and methods for using such systems in electric vehicles are disclosed. In one embodiment, an example electric vehicle may include a drive motor configured to impart motion to one or more wheels of the electric vehicle, a plurality of batteries configured to power the drive motor, and one or more controllers. The plurality of batteries may include a first battery including a first cell having a first chemistry, and a second battery including a second cell having a second chemistry different from the first chemistry. The one or more controllers may be configured to cause the first battery and the second battery to power the drive motor, and to cause the drive motor to charge the first battery and the second battery.

Abstract: Systems, methods, and apparatus for providing a homopolar generator charger with an integral rechargeable battery. A method is provided for converting rotational kinetic energy to electrical energy for charging one or more battery cells. The method can include rotating, by a shaft, a rotor in a magnetic flux field to generate current, wherein the rotor comprises an electrically conductive portion having an inner diameter conductive connection surface and an outer diameter conductive connection surface, and wherein a voltage potential is induced between the inner and outer diameter connection surfaces upon rotation in the magnetic flux field. The method can also include selectively coupling the generated current from the rotating rotor to terminals of the one or more battery cells.
Abstract: Systems and methods are disclosed for adaptive regeneration systems for electric vehicles. In one embodiment, an example method may include determining, by an adaptive regeneration system, that an electric vehicle is decelerating, determining an output voltage of a power source at the electric vehicle, determining that a voltage potential of a battery system at the electric vehicle is greater than the output voltage, and causing the voltage potential of the battery system to be modified to a value equal to or less than the output voltage.
