I just called the dealer and they verified the car's VIN and mine is not affected by the recall.

So, knowing that model has been used on 240V, you have the opportunity to increase your charging speed and allow the car to run battery conditioning if it chooses. Faster charging may also allow you to finish charging before you hit peak hours again and may also trigger proper enforcement of value charge times - but I can't guarantee that. Making an adapter can be pretty simple. Most plug types have a screw terminal version where you can open it up, clamp down wires and it back together, but the specifics would depend on the type of 240V plug it would use.

That, of course, assumes you have access to 240V and want to use it. I know that the manual tells you not to use an extension cord BUT that is there because most people do not know how to properly size one. If you have a proper 16A rated extension cord it would work fine for your 12A charging, though you still want it to be as short as possible. Real heavy duty extension cords can be expensive (lots of copper) but can handle a lot more than this.

Something like this has 12AWG copper rated for 15A https://www.acehardware.com/departments ... ds/3009024

A good rule of thumb for extension cords is to make sure the number stamped on the jacket is the same as the device you're using or lower (it's reverse, smaller AWG numbers are thicker wire) and to go to the next larger size if you have to go more than like 50ft.

This is the 240v outlet I have in my garage. It's hooked up to a 40amp breaker.

Easy enough, you you might want a little pigtail if you can't flip that outlet over

I'm a bit lost as to what I need to do exactly. Cut the 120v charger cable and attach the 6-50 pigtail from Amazon? Then plug that directly into my 240v outlet?

No. You'd take that Amazon plug (or one like it, a store like Home Depot will have them) and put a regular 120V socket like this on the other end using a little bit of 12AWG wire.

You just have to make sure you never plug anything else into that adapter. You could modify the plug on the charger itself but it would be more involved than just splicing the plug on.

To help remind me that I have 240 at the receptacle, and not 120 as you would think, I used a bright orange-red connector from Home Depot.

This was for a step up transformer used to power foreign appliances.

Oh I think I understand now.

Use a male 6-50 plug and female 5-15 plug and join them with 12AWG cable.

Interesting.

While it can add up, having a selection of adapters can be quite worthwhile - especially if you have a portable L2 charger.

Image

From top left:
50A J1772 cord
J1772 Plug to NEMA L14-30r
NEMA L14-30 extension
J1772 Receptacle to NEMA L14-30p (and spare twist lock 14-30s)
Tesla Receptacle to J1772 plug (TeslaTap)
Ford 120V/12A convenience cord (rebadged Clipper Creek EVSE)
NEMA 14-50p pigtail
NEMA 14-30p pigtail
NEMA 10-30p pigtail
NEMA 5-15r to L5-15p
NEMA L5-15r to 5-15p
More spare twist lock 14-30s
NEMA TT-30p to 5-15r
NEMA 6-50p pigtail
Spare 3C 12AWG sections with WAGO lever nuts

Image

Grab square and hex ferrule crimper sets and some WAGO 832 series pluggable terminal blocks and there's not much you can't do.

I should note that the NEMA plugs that have J1772 hardware on the other end have the pilot wire carried through on the ground pin - which means I can use a real 4 wire L14-30 extension to extend the J1772 side of my charger if needed (or use that J1772 receptacle to extend an existing charger connection). When I put all that together, I can plug my car in 8-10 spaces away from an existing charger or I can otherwise use pretty much any 120V or 240V down to literal bare wires.

That's all too complicated for me. lol I'll concentrate on one for now.

6-50 plug:

https://www.amazon.ca/Eaton-S42-SP-Comm ... 6X22&psc=1

The description in there says to use minimum 10 AWG wire.

Wire:

https://www.amazon.ca/Southwire-2882902 ... =8-13&th=1

5-15 plug

https://www.amazon.ca/Leviton-515CV-Gro ... 14&sr=8-19

Does all that sound right?
