1. A wireless rechargeable battery system comprising:
an electrical energy storage element for a wireless rechargeable battery;
a wireless receiver for the wireless rechargeable battery, wherein the wireless receiver is configured to supply electrical energy to the electrical energy storage element in a presence of a magnetic field from a charging base station;
an internal electronics circuitry for the wireless rechargeable battery, wherein the internal electronics circuitry couples the electrical energy storage element and the wireless receiver; and
a battery casing that holds the electrical energy storage element, the wireless receiver, and the internal electronics circuitry,
wherein the wireless receiver comprises a plurality of magnets supported by a suspension structure on opposing sides of the plurality of magnets within the battery casing and a plurality of receiver coils, wherein the magnetic field induces the plurality of magnets to oscillate and generate an AC voltage in the receiver coils, wherein the internal electronics circuitry converts the AC voltage to a DC charging signal that is applied to the electrical energy storage element.
