A method of operating a medical device comprises electrically connecting a power device to the medical device. The method further comprises sensing at least one characteristic of the medical device with the power device. The method further comprises adjusting or maintaining one or more characteristics of an electrical connection feature of the power device according to the at least one observed characteristic such that the electrical connection feature of the power device is operationally compatible with an electrical connection feature of the medical device. The method further comprises operating the power device according to an operational profile associated with the medical device.

An interconnect is disclosed that opens a battery circuit when an access cover is removed. The interconnect includes a single installed position, and does not include any throw positions to avoid ambiguity. The interconnect includes a conductive element that closes the battery circuit when the interconnect is installed. The access cover cannot be removed when the interconnect is installed, because the interconnect includes at least one mechanical feature that prevents removal of the access cover. In some instances, the interconnect is integrated into the access cover, such that when the cover is removed, the circuit is opened necessarily during removal. The interconnect interface may include blades, pins, or other electrically conducting elements. The interconnect is arranged in the battery system away from power electronics and other components that may interface to an electrical load, thus providing an added measure of safety when the access cover is off.
