1. A battery maintenance system for use in performing battery maintenance on a battery of an electric vehicle comprising:
a battery maintenance device; and
a high voltage connector configured to connect the battery maintenance device to the battery of the electric vehicle, wherein the high voltage connector comprises:
a first connector side coupleable to the battery of the electric vehicle and including a plurality of first type of connector poles and a keying post, wherein the keying post has a distal end that terminates a distance from ends of the first type of connectors;
a second connector side coupleable to the battery maintenance device and including a plurality of second type of connector poles configured to electrically mate with the plurality of first type connector poles of the first connector side, a fuse block including at least one fuse and a removable fuse door having an interlock, a mechanical component configured into a first position and a second position and an electrical switch configured to disconnect and connect voltages from the fuse block;
wherein when the fuse door is removed from the fuse block, the mechanical component is in a first position that blocks the keying post and prevents the first connector side from coupling with the second connector side; and
wherein when the fuse door is in place and covering an interior of the fuse block, the interlock of the fuse door places the mechanical component into a second position to allow the keying post to mate with the second connector side and to activate the electric switch to connect voltages to the fuse block.
