J1772 is not just the connector. It's a specification that provides safety protection and allows electric vehicles to sense the voltage and maximum current of the device ("EVSE") they're plugged into so they can charge accordingly.. The "box" contains the relays and circuitry that make that happen. Some boxes bigger than others; sometimes they're just a "brick". An EVSE can be hardwired or it can have a plug. If equipped with a plug, the cord from the plug to the "box" or "brick" is typically quite short (less than a foot). This is to minimize the length of cord that is "live" and unprotected by the EVSE safety features.Yanni wrote: ↑Thu Sep 05, 2019 4:44 amCan we just buy a charging cable that is J1772 on one end and a 220v plug on the other...and then plug it in to the new outlet the electrician installs? Do we NEED a "box" on the wall just to accomplish this? If not...what is the benefit to having a box (I assume it's hardwired) onto the wall?
Yes. However, I believe current electrical codes limit the cord on plug-in EVSE's to 12 inches. Just something to keep in mind if you do install a receptacle for the EVSE. If that causes a problem you will probably have to get a hard-wired unit.
Another possibility is to trade the Level 1 EVSE (NEMA 5-15 plug) that came with your Leaf for a Level 2 EVSE (NEMA 14-50 plug and adapter for NEMA 5-15) from a 2018 or 2019 Leaf. I traded my 2015 Leaf EVSE and $100 for the robusto Level 2 EVSE that came with a 2018 Leaf whose owner preferred to have the cash and the more gracile Level 1 EVSE.davewill wrote: ↑Thu Sep 05, 2019 11:18 amYes, you can buy a "cord" that plugs into the wall and then into the car. Usually the cords with a plug on them are considered to be for portable use, but there's no real downside to using them at home. The price depends on the amperage they can deliver. Here are links to a few possibilities, but there are many, many more.
