Each receiver measures its own battery need for power and transmits that measurement as a request to the transmitter. The transmitter is configured to normalize and compare battery need requests. The transmitter then allocates pulses of wireless power among the requesting receivers according to their battery need. ## Claims ### Claim 1 A wireless power transmission apparatus comprising: allocation means for allocating wireless power pulses among wireless power receivers in accordance with battery charging requests received from one or more of the wireless power receivers;
