A system and method for powering or charging multiple receivers wirelessly with a power transmitter. In accordance with an embodiment, to enable ease of use, it is desirable that the receiver can be placed on a larger surface area charger without the need for specific alignment of the position of the receiver; that the system can be used to charge or power multiple devices of similar or different power and voltage requirements or operating with different wireless charging protocols on or near the same surface; and that a degree of freedom is provided with respect to vertical distance (away from the surface of the charger) between the charger and the receivers. Such features enable improved functionality with devices, vehicles, or other products, including, for example, charging of electric vehicles (EV), and trains. |
