Wireless charging for Super Capacitor

A wireless charger that can charge a Super Capacitor [SC]. It would have an adjustable maximum voltage of 2.0 to 2.5 volts, and be able to dump large amounts of current [5A or more -- much more] into an extremely low impedance load [i.e. a current source with an upper voltage limit]. Also, it should be able to dump current into the SC at full bore all the way up to the maximum voltage. A typical SC has a maximum voltage of 2.7 volts, but should not be charged higher than around 2.2 to 2.5 volts [the higher the voltage the lower the live expectancy so it's a tradeoff between performance and longevity]. Also, when a SC is fully discharged, it behaves like a direct short with a high current capacity path, so this wireless charger must be able to handle that without issue. The current sourced by this device doesn't need to be regulated and can even be a pulse of some sort [i.e. the raw, rectified output of the receiver] -- just as long as the voltage across the capacitor doesn't exceed the maximum voltage.
