I would prefer to have a socket over a fixed cable. I see a variety of sockets that say they support up to 22kw on aliexpress and other places. Just wondering if anyone has done this and if there is a recommended approach to doing this. It would seem that I could just put a hole in the cover somewhere where there is enough clearance in the housing for the back-side of the socket and then wire it up the same as a fixed cable was wired.

Maybe there is some reason this is a bad idea?

• Sockets must have an electric locking mechanism that locks the cable’s plug while a car is charging. If the plug is not locked, it can be unplugged while energized, which will cause arcing that will corrode the socket and plug and may cause a fire in the long run. WARP Chargers don’t have the electronics or control logic to drive a locking mechanism, even if you tried to add one. My guess is that many of the sockets on Aliexpress don’t even have a locking mechanism in the first place and you’re expected to just YOLO it.

• There’s no room left inside the housing to install a socket. There were plans to make a WARP Charger with a socket because there’s some demand for that, but there was simply no way to fit it in there.

Thanks. Exactly the info I was looking for. So to sum up (so you can let me know if I misunderstood)...

• would need to mount the socket in an additional housing (e.g. another enclosure mounted to side of the warp) due to lack of space in the warp enclosure for socket

• would need to locate a socket with locking mechanism to avoid arcing problem.

• would need to add feature to firmware to support locking assuming there is even appropriate hardware IO available to control the lock. (this is probably the biggest issue).

That is correct.

That’s actually quite possible. The charger’s controller board has two extra extension ports for Tinkerforge Bricklets. You could use something like a Quad Relay Bricklet and an IO-4 Bricklet to control and monitor the locking mechanism. This still requires quite a bit of programming to extend the firmware to use the locking mechanism and block charging until the socket is locked, though, so I would consider the software to be a bigger issue than the hardware.
