This was actually really helpful, as I hadn't realized that Tesla to J1772 adapters existed. I'll definitely have to buy one before/when my Mach E arrives (especially given that I won't have home charging and will be relying on work charging).

I have a Tesla wall charger installed and will get an 80A-capable JDapter. They're pricey at $300 or so, but it means I can charge anywhere there's a Tesla or J1772 plug. Additionally, many Tesla wall chargers are at 48 or more amps while most J1772 home chargers are 32A.

Tesla HPWC $500 + $300 adapter =$800
48A home charger = $900+

BUT.....does the Mach E max out at 48amps? IF you run an 80 amp breaker, the car may only charge as if there was a 60 amp breaker and max out at a continuous 48 amps? Some of us have installed a 50 amp breaker to run a continuous 40 amp on a 14-50 NEMA outlet which is found outdoors. This setup might not produce 32 miles of range per hour but at 29(?) it would be close and more cost effective when one considers using a 80amp breaker, you need a thicker wire (6awg for 50 amp breaker) which cost significantly more than 6awg.

The Mach-E's internal charger is 11kW which means max current at 240V is ~45 amps (minus some that gets converted to heat). Do you really need to charge it that fast? Do you expect to drive 300 miles every day?

I have my home Level-2 set for 30amps and, in the winter, charge up our Bolt every night. I use about 1/3 of the battery daily so it only takes about 3 hours max to charge it up--its always "full" before I go to work ("full" -- I have it set so that it doesn't charge to 100%). Note that I also like to keep the car plugged in at night in the winter so the battery conditioning can keep the battery toasty warm.

Now in the summer months, I charge the car to 100% about every 4th day--I don't even plug it in at night for the other 3 nights (I run the battery down to about 1/3 since I easily get 250+ miles).

For the 300 mile Mach-E I would expect to do something similar: only charge it every few days (heck with 300+ miles of range in the summer I'll probably only charge it once per week).


That video is really well done and should be required viewing for any newbie EV owner.

Nitpicking but isn't the Mach E internal charger 11.5kWh as is Tesla?

The only thing I found on the web said 11kW--it could be 11.5kW (note kW is a "rate" and kWh is a "capacity" hence a charger can charge at 11kW and a battery can hold 98kWh--yeah also nitpicking).

For the video, nothing was mentioned about air cooled battery packs as frequently (in the past) found in Plug in Hybrids. Charging produces heat. EV driving produces heat. Some hybrids have an issue with battery degradation from excess EV usage and charging. These battery packs do not manage heat very well especially during the warm (er) months of the year. Then one really should not keep their battery level at 100% all time which is not good for a long life span.

Here is a real down - to - earth video from The 8-bit Guy. He usually does videos on computer gear, especially older gear. He does not do videos on EVs. However, I thought his latest video was very informative for just this reason -- he's truly an "every man" and this video is heavily geared to non-EV folk. Here is his answer to the question of "How long does it really take to charge".

This is a good basic intro to charging. He's also done a couple of videos on his BMW i3. As the video points out, "how long to charge" depends on several things. I'm not sure he mentioned it, but battery temp. is one as is the charging curve set by the EV manufacturer. I'm anxious to see the curve for the Mach-E. BTW, I haven't seen any manufacturer publish a curve....enthusiasts gather the info and publish it on forums like this one.

Very helpful to me as someone new to EV and all the charging vocabulary. It can get confusing for a newcomer.
