Mine is behind the license plate and uses a standard door/window switch from an old store alarm system. Just a magnet on the plate and a reed relay that switches when the plate is latched closed. Reed relay grounds the interlock relay, while the key switch supplies 12V to the other side of it's coi

The Skoda Elmo pickup had a simple system. The charge cable was captive to the vehicle and stored in a compartment behind what was the grill. A socket was fitted in the compartment and plugging the cable in completed a circuit via the earth pin that operated an interlock relay. This also meant tha

I have never understood why the NEC _requires_ an EV charging plug be "locking". It makes no sense. If you drive away (or the vehicle somehow rolls, is towed, or moves away) the plug should simply come out. As it is now, the locking plug won't give, so the cord breaks, or worse, the charger

I have a standard (RV/boat style) male NEMA 5-15 plug mounted in the air dam on the truck, so a standard extension cable plugs into it. The 5-15 male plug is isolated from the J1772 plug by a relay. When 120 volts is seen by the 5-15 plug, the relay switches the chargers over from the J1772 pl

If you have a conversion EV, please make sure that when your charger is plugged in something disables your motor/controller so that the EV can't drive away. This is especially important if you are using a twistlock, or J1772 connector, but even pulling out a NEMA 5-15 by the cable isn't optima
