[0035] 其中η为无线供电模块12输出总输出能量Ptll的传输率。 [0035] wherein η is the rate of the transmission output of the wireless power supply module 12 of the total energy output of Ptll.

[0036] 然而各无线接收模块14_l_14_a应用于能量需求量不同的电子装置中。 [0036] However, different power requirements of the electronic device 14_l_14_a used in various wireless receiving module. 举例来说,无线接收模块14_i及14_j系分别应用于无线鼠标与行动电话中,无线鼠标的能量需求量小于行动电话的能量需求量,其中i与j为小于或等于a的自然数。 For example, the wireless receiving module and 14_j 14_i lines were applied to mobile phone and a wireless mouse, wireless mouse energy demand is less than the energy demand mobile phones, where i and j are less than or equal to a natural number. 在一个操作实例中, 无线接收模块14_i接收并储存至电池的系统能量讯号对应的能量系高于无线鼠标的能量需求量,而无线接收模块14_j接收并储存至电池的系统能量讯号对应的能量低于行动电话的能量需求量。 In one example of operation, the wireless receiving module to receive and store energy 14_i demand signal corresponding to the energy-based power system to the battery is higher than a wireless mouse, and the wireless receiving module receives 14_j signal corresponding to the energy storage system and to a low battery power energy demand in mobile phones. 如此,无线接收模块14_i透过其中的无线收发模块将额外的能量提供至应用于行动电话中的无线接收模块14_j。 Thus, through the wireless receiver module 14_i wherein the wireless transceiver module to provide additional energy is applied to the wireless receiving module 14_j mobile phone.
