Plugshare is crowd sourced. That can be good. But sometimes you get a report that isn't quite accurate. Or worse. It is not a bad first place to look. Do have your salt shaker handy. Usually accurate, but not always. The really good part is getting information on non-networked stations...

Done in two steps for every system I've looked at. Rectified and filtered to DC with some ripple, then put into a DC to DC converter. Amusing. A Youtube teardown of a power supply, including a "cat move a little bit. Go go go." https://www.youtube.com/watch?v=B19rB_FR5Mk

This isn't a graph of the Bolt's charger, which is just a high power DC to DC converter with an adjustable output voltage and current limits, but is of a more common part with much lower power output. Do you really want to dive into DC to DC converter design? I've designed some low power...

Efficiency is higher at higher charge rates.

Are you sure these were not 50 Amp outlets? Almost all RVs use TT-30 or NEMA_14-50. https://en.wikipedia.org/wiki/NEMA_connector#NEMA_TT-30 Three connectors: Hot, neutral and ground. Most RVs are wired for 120V 30 Amp. Large RVs use 240V 50A...

30 Amp RV is a "TT-30", which is 120V 30 Amps. It is NOT a 30A dryer. Some cars can charge at higher rates than 1.440kW on 120V if the EVSE advertises more. Some cars do not. I don't know about the Bolt.

J1772 is limited to 80Amps or 19.2kW for L2. The Bolt is limited to 7.2 kW. The lowest of the car's charger and the station's specifications limit the total. 7.2kW is the most common, however many public stations are 208V 30 Amp or 6.240kW. There are lots of others, some stations I have used...

Usually in fairly remote places. I've charged my Leaf at 6kW on a J1772 that would support 70+ Amps several times. It would have been nice to charge more than twice as fast. Dual charger, or similar, probably as an extra cost option, would be a nice thing for my next EV. Only Tesla offers this...

Generally, slower. With no heat/AC or wind or hills, somewhere around 10 to 20 mph is about the best. Faster if running heat, AC, or other major current uses. Wind and hills make it complex, see hypermiling. How fussy do you feel? Simplest way to improve battery life is perhaps to set the car...

Thanks.

I don't care to guess. So I ask. Also, I'd guess that the kWh is plus or minus a few percent. But how many percent, I don't care to guess.

How accurate is the kWh reported by a Chargepoint station? Is it kWh delivered to the car, or is it adjusted for some charging efficiency estimate? If adjusted, by what percentage?

My wife would love it. I prefer red cars.

Eventually, competition. Do I stop at Brand X for $x or Brand Y for $y? Probably depends on if x>y or y>x. And who has the best coffee.

With hilltop reserve on, this probably doesn't matter very much. If hilltop reserve was at 70% rather than about 90%, it wouldn't matter at all. Charging to 100%, then discharging and recharging by a tiny amount will degrade a battery more quickly than charging to lower percentage and doing the...

Taking a long view, China has been the most technologically advanced country most of the time. Sometime around 1400AD, Europe started a technology explosion that China didn't match. China was farming with iron plows when Europe and the rest of the world was pushing sticks into the ground...

Like paper, of course. And gunpowder. All American technology.

Not all RV parks have 50A. Many have just 30A TT-30's. 120V, 24 amps charging. An adapter for RV park usage should have both options covered. I don't know of any that can be bought out of the box that can do both. Not even Tesla, but there is (might be? I have not seen a physical one) a third...

Knob and tube wiring? Don't pass go, get a 240V L2 installed. Do not turn your car up to 12 Amp charging rate, leave it at 8 Amps. And if you need more charging short term, there may be public charging stations around. See: https://www.plugshare.com/ Maybe fuse box? Maybe 60 Amp service? If so...

EV 101: Did you have the current set to 12 Amps, or the default 8 Amps? You add a bit more than 1kWh per hour or 4 to 5 miles of range per hour on the higher power setting. You have a 60kWh battery. On 120 V, 12 A, it takes 50 or more hours to charge from near empty to full. Or 30 hours to go...
