Maybe I'm missing something here, but why not use a 4-pin inlet, perhaps similar to a modern clothes dryer plug? With the proper relays, connecting 120 volts to neutral and one hot would activate the 120v charger and connect it to the battery; connecting 240 volts to neutral and the other hot would activate the 240v charger and connect IT to the battery. There'd be no exposed live pins that way. Make two pigtail adapters or inlet cables, one for 240v and another for 120v. Not as elegant as some kind of automatic switching, but it should work. Or is this somehow impractical? I'm just an electronics hacker (in the positive sense), not an engineer.
