Methods, transmission devices and transmission control system for transmitting power wirelessly
First Claim
1. A method of transmitting power via electromagnetic coupling from a transmission charging device to a set of reception devices, wherein each reception device defines a first given power level specifying a power requirement required by each reception device, the method comprising:
- calculating by the transmission charging device, a first sum of the first given power levels defined by each reception device of the set of reception devices; and
when a maximum power that can be transmitted by the transmission charging device to the set of reception devices is less than the first sum,identifying, among the set of reception devices, whether there are any reception devices defining a second given power level which is lower than its first given power level; and
determining by the transmission charging device, according to the identifying and a predetermined criteria, a subset of reception devices among the set of reception devices, to which the transmission charging device transmits power.
