Gas Cap Battery Charger Plug Installation

Well, I just got done with something on the car that really isn't a big deal, but still feels like a little bit of a milestone.

I installed a power inlet where the gas cap used to go.

Using materials I already had - Romex household wiring, some flexible conduit, and bits of scrap metal, I was able to make the car look like a "real" EV.



I fished the Romex through the conduit by pulling it through with some rope. I put the one end through the drain plug in the bottom of the spare tire well in the car. It's a hole that's already there, all I had to do was pull out a rubber plug. No drilling!

I pulled the other end of the conduit wiring up to where the gas cap was.

I bought the power inlet plug at the local marine store. I believe it is the EXACT same plug as is used on the ZENN.

However, the plug was just a little smaller than the hole I had for the original gas filler tube.

I cut the lid of a coffee can to test fit what I needed for some sort of a "hole reducer".



Once I had the plastic the right size and shape, I used it as a template to cut a piece of scrap galvanized sheet metal to the same size. The sheet metal went behind the hole and was attached with 3 sheet metal screws through the holes that originally held on the gas filler tube.

I also installed the 3 small black screws through the rim of the power inlet. They help snug it up a little more, plus, they look right in there.



On the back of the power plug, there are three holes you just slide the stripped black, white, and ground 120AC wires into and tighten down a screw for each. Then a rubber boot slides up and over the back of it.

I made sure the conduit was slid up nice and tight to the rubber boot, and wrapped a little electric tape around it just to be safe.

Looky here - an actual "official" charging setup!




PS: There is also a black and a white wire that come off the back of the charger. This is an AC output. I think it is designed to run an AC solenoid that will disconnect power to the motor controller when the charger is plugged in. That way, you can't drive the car off while plugged in!

I was thinking that maybe I could use that power out to supply AC to the 1.5 amp trickle charger I have up front which runs the accessory battery. I don't know how many amps can go through that extra output on the charger. I don't think a lot, but probably enough to run a very small charger?
