Wireless charging locking device
View Patent ↗A system for wirelessly transmitting power between a mobile device and a locking device is provided. In one embodiment power is wirelessly transmitted from the locking device to the mobile device. In another embodiment power is wirelessly transmitted from the mobile device to the locking device. In both embodiments power is transmitted wirelessly when the storage of power is below a critical level in one of the devices (e.g., the mobile device or the locking device). When the power is at a critical level the device (e.g., mobile device or locking device) may not be able to complete a function (e.g., transmit an access credential or actuate a mechanical or electronic lock). As such, wirelessly transmitting power between the mobile device and the locking device may enable the function to be completed.
