Abstract: Apparatus for transferring power to through an isolated, insulated connection. A power transfer assembly includes a portable cable assembly and a receiver. The portable cable assembly includes a power plug and a transmitter with a plug portion that mates with a receptacle on the receiver. A magnetic latch secures the plug portion in the ring receptacle. The transmitter includes a power supply, a power switch, a signal sensor, and a transmitting inductor. The receiver includes a receiving inductor, a signal coil, a magnet, a power converter, a temperature sensor, and an isolation switch. When the transmitter is coupled with the receiver, the power switch is operated by the magnet, the signal sensor is magnetically coupled to the signal coil, and the transmitting inductor is magnetically coupled to the receiving inductor. The normally open isolation switch is operated when the power converter is energized by the transmitter.

Abstract: An apparatus for selectively charging a variety of batteries. A battery charging system includes a charging circuit, a processor, and a key, or identification device. The key has a value or code associated with the type of battery to be charged. The processor executes a software program that reads the value associated with the key. The software program charges the battery in a manner required by the battery type associated with the key value. In another embodiment, the program checks for changes to the key, such as when an operator swaps the key during charging.
