Newb questions
Please bear with me as I am totally new with electric cars. We are having some electrical work done on our house and figured we would have a 220V plug (I am in the US) put in. What sort of connector or adapter do I need to tell the installer to put in? Also, how long of wire can you run to the car?
Thank you.

For example, the ChargePoint Home Flex Electric Vehicle (EV) Charger is available with a 23ft cable, and either a NEMA 6-50 or 14-50 outlet for plug-in (40A to 50A), or for hardwired installations (48A-50A). There is a $1000 tax credit for EV chargers and installation up to Dec 31, 2121. |

IMO, get a plug in charger install with a NEMA 6-50 socket. You can always change the socket if needed, and move the charger to another location by just unplugging it. Last edited by Encanto; 11-01-2021 at 08:26 PM.. |

Get something that supports 50A. Some have wifi and other features like lockout, etc. I have a very basic one because the smarts are really in the car for charging. Or you can do like others have said and install a plug. You can always remove the plug later and hardwire.

if you have an "existing" electric dryer plug you can use that since it is 240v. Usually 40A. Dedicated circuit as you describe. Mine is installed with a dedicated 50A circuit. I installed L2 when I got my first EV.

Here in the US, I had my electrician install a NEMA 14-50 socket on a 50 Amp breaker. I did not want to get a Tesla wall charger hard wired, and instead opted to use the Mobile Connector that came with the car and plugs into the 14-50 socket on a more or less permanent basis. Why? I don't really need the mobile charger all that often, as I don't road trip and when I do, there are enough superchargers on my route that there is usually a backup. I really should bring the Mobile Connector with me, just in case I really need a backup, like a 110v or plugging in at an RV park. The other alternative is a hard wired EVSE. This means if your car comes with a mobile charger, you can keep it with the car as a backup / more options plan. It's also a little neater, and usually has a higher amperage rating. The Tesla Mobile Connector is rated for 32A while the wall box can go higher (48?). But 32A is plenty for charging my car overnight so I don't bother. Either way works, it's your preference. Since I have a 14-50 already installed, I plan on getting this Clipper Creek unit so that I can have an EV and we can add a PHEV for my wife. I'll get this unit as soon as she orders her PHEV. https://store.clippercreek.com/level...ema-14-50-plug But you can see that clippercreek has the same exact unit, but in a hardwired version. https://store.clippercreek.com/level...arging-station |

I'm in the US and already have a Tesla wall charger installed for my son to use who has a M3. It has worked flawlessly and I plan on using a Tesla to J1772 adapter for when the i4 is delivered. Interesting that Tesla now sells a version of their wall charger with a J1772 plug. This may be Tesla's go forward standard as they already have an inexpensive J1772 to tesla adapter and superchargers are being opened up to any EV. I think the Tesla J1772 wall charger is less expensive than the other brands, although it's their more simple V2 (no remote/WiFi capability).
I like having a separate home wall mounted charger so the portable charger can always stay in the car. And yes, technically these all are just cable and relay systems, the actual L1/L2 charger is in the car. |

The i4 will have a 240V 9.6KwH included. It looks like it will come with adapters for NEMA 6-50 and NEMA 14-50 sockets.

It comes with the portable cable that has different adapters to plug into outlets ranging from 120v 15 amp to 240 volt 50 amp. I would keep the L2 wall box so the cable is always in the car. Just like The credit card, never leave home without it.

Basically it detects if I reach a consumption of 80% of the limit of my panel, if so it cuts the charging station for 15 minutes and restarts the station only when the threshold below 80% is reached. I also needed 40 'of cable for the terminal and the maximum I saw is 25'. There are plug and play extension cords, I bought a 25 'extension. Professional advice should be sought, not just an electrician but an electrician who has experience with these products. |

I would recommend asking your electrician to lay a 6-3 wire from your panel and to a spot near where you would install your charger. The wire can be terminated in an appropriate electrical box so that once you do buy an EV and charger, it will be very easy to make the final connections. A 6 gauge -3 wire cable will support 50 amps at 220-240V. The electrician can also install the 50amp 220-240V breaker now or later. Tye key is running the cable now while your doing general electrical work

I ran a 6-3 (don’t need the neutral on 220 but it’s there) and hard wired a enel-x 40. It’s in between the back of where the iX and i4 will sit. I’ll keep the ones that come in the cars as backups for travel if ever needed. |
