Because I don't need 40 amp breakers, or a J1772, and I can find better uses for $700. The whole point of DIY is building to your needs. An overnight charge is just fine for me, and there is nowhere else for me to charge at. I'm considering pulling out the onboard charger anyway as I've plugged in away from home a whole 2-3 times.

I was able to keep a closer eye on the charging tonight. I put on 37.2 miles today and it appeared to bring the dashboard meter up to full in less than 3.7 hours. That makes it a 10 mph charger. The wall meter indicated 11 kWh, so about 295 Wh/mile. Maybe 80-85% of the trip was 60 mph and remainder 35 mph stop and go.

You mean you do need the breakers and the J1772 but don't want to spend any money. Be honest with the readers.

If you don't want to use the public J1772, that's fine. Probably because it costs money. Isnt it good others don't walk in your shoes when driving a EV needing a charge? I don't push anything, contrary to your unfounded remarks which seems to be a pattern with you. It is the standard for ALL EV's and we should use the standard as a guide. I don't get royalties on anything, another remark using your poor taste.

Um...no. I don't need them. I'm usually home for 16 hours, why do I need to charge in 4?

I don't know why you're pushing the J1772 so much, it's like you get royalties on it or something. A J1772 is WORTHLESS to me. I wouldn't install it if you paid me to.

I no longer have a charger in my car. I pulled it out a few months ago when I was doing some work on the car, just never got around to re-installing it. No big deal, for the once a month or so trip where I think I may charge away from home I'll throw it in the trunk, but for the most part I do all my charging at home.

Fwiw, I charge at around 3 mph and it fits my driving needs just fine. I do have the itch to get a much higher power charger, but it's definitely a want and not a need.

Hi All,
After reading thru this thread, it seems to me that the MPH way of describing charging leaves out the watt per mile factor.
If your car uses 500 watts per mile then it will charge 1/2 as fast with the same charger as a car that uses 250 watts per mile, right?
Also uphill miles are not the same as downhill miles in charge usage.
So, why is this an improved way of discribing charge rate over staight energy input?

That's correct. It can be specific to your car, or you can use a generic value like 250wH/m, which makes math easier as well. It's just a way to make it easier for people to relate to, by saying I charge at x mph, instead of speaking in Klingon about amps and watts and volts.

Just like normal MPGs, they don't account for up or downhill, speeds, etc.

Hey Joe,

I mentioned in post #1:

The mph figure is more of a personal metric, not a sales specification for chargers.
