An enclosure for a wirelessly chargeable battery includes a housing having a base and an opposing open end, where a hole is bored through the base. The enclosure includes an end piece attached to the housing proximal the base and having an opposing open end. The enclosure includes a first conductive coating formed on an interior surface of the housing and a first surface of the base, and a second conductive coating formed on an interior surface of the end piece and a second surface of the base, where the housing and the end piece are configured in dimensions that conform to standardized battery dimensions. Battery cell(s) may be positioned inside a cavity in the housing, and circuitry may be positioned inside a cavity of the end piece. The enclosure enables highly efficient use of interior space and volume of the enclosure to maximize battery charge capacity.

Devices and systems for providing wirelessly chargeable batteries with improved charge capacities

The technology is generally directed towards wireless power charging of one or more receiver devices within a container that is electromagnetically shielded with respect to the frequency or frequencies used for the wireless charging. A controller determines, via signaling from one or more sensors, that the container is in the electromagnetically shielded state with respect to emitting external radiation at the charging frequency or frequencies. When electromagnetically shielded, the controller controls the output power state of a wireless power transmitter device to charge the one or more receiver devices. The controller can determine when to stop the charging of a receiver device, such as when sufficiently charged. The controller and wireless power transmitter device can charge the one or more receiver devices selectively, e.g., based on which one needs more charge or other criterion. The controller can obtain and externally communicate the state of charge of the receiver device(s).

Controlled wireless charging in an electromagnetically shielded environment

Systems and methods are disclosed for wireless power delivery that can provide wireless power, via a retrodirective wireless power transfer (WPT) channel, to a wireless power recipient in response to a modulated backscatter signal from a wireless power receiver. A wireless power receiver can produce a modulated backscatter signal and transmit such to a power delivery system to initiate a wireless power transfer linkage. In some examples, a dual-band technique can be implemented where a first band can be used as a dedicated retrodirective WPT channel while a data communication node can utilize a second band for a low energy compatible data communication type. Both a beacon signal (the backscattered signal) for retrodirective linkage at the first band and the communication signals at the second band can be produced via backscattering at the wireless power receiver. A backscattered beacon signal and a communication signal may be modulated and frequency multiplexed.
