Bi-directional wireless charger

摘要

A bi-directional charging device includes a rechargeable battery, a coil coupled to the rechargeable battery, a selection mechanism that selectively causes power to be delivered from the coil to the battery and selectively causes power to be delivered from the battery to the coil, and a control mechanism. Upon determining that the coil is to provide power to the battery, the control mechanism causes the selection mechanism to selectively cause power to be delivered from the coil to the battery, and upon determining that the coil is to receive power from the battery, the control mechanism causes the selection mechanism to selectively cause power to be delivered from the battery to the coil.;The bi-directional charging device includes a housing enclosing the rechargeable battery, the coil, the selection mechanism, and the control mechanism.

1. An apparatus, comprising:
a rechargeable battery; a coil coupled to the rechargeable battery; a selection mechanism that selectively causes power received wirelessly through the coil to be provided from the coil to the battery for wireless charging, and selectively causes power to be provided from the battery through the coil for wireless power transfer; and a control mechanism that
upon determining that the coil is to provide power to the battery for wireless charging, causes the selection mechanism to selectively cause power to be provided from the coil to the battery; andupon determining that the coil is to receive power from the battery for wireless power transfer, causes the selection mechanism to selectively cause power to be provided from the battery to the coil; a housing including the rechargeable battery, the coil, the selection mechanism, and the control mechanism.
