Charge interlock

seems a good idea for a number of reasons, not least that the controller may be damaged

this may be a nice option?

good discussion here - wiki may be relevant for other stuff as well

This photo seems to show the electric echo "interlock" on the fuel filler door

I dont believe that is fully mechanical - looks like it goes into the control of the contactor

I should be able to use a relay such as this one to only connect the charger when it is on:

Actually - on second look, the input can only be to 36V - I should still use a relay such as this but will have to be driven from the 12V charger.
