Abstract:
1. An inductive power supply system comprising: an inductive power supply including a primary circuit and a primary for wirelessly transferring power; a remote device separable from said inductive power supply, said remote device including a secondary for wirelessly receiving power from said inductive power supply, a battery having a battery type, and a secondary circuit that includes a battery characteristic detection system for detecting a characteristic of said battery indicative of said battery type, said characteristic of said battery including at least one of a battery voltage characteristic, a battery current characteristic, and a battery temperature characteristic; a memory located in at least one of said inductive power supply and said remote device, said memory including a plurality of wireless power charging algorithms; a communication system for wireless communication between said remote device and said inductive power supply; a controller adapted to communicate with said memory, said controller located in at least one of said inductive power supply and said remote device, wherein said controller is programmed to select a wireless power charging algorithm from said plurality of wireless power charging algorithms in said memory based at least in part on said detected battery characteristic indicative of said battery type; and wherein said primary wirelessly transfers power from said inductive power supply to said remote device according to said selected wireless power charging algorithm.
