Please let me know how in layman’s term how I can do this. I am current using an extension cable off a 5-15 regular household receptacle and a charger off Amazon to get 4 miles per hour range. I would like to get that 2 miles per hour range if possible

MEGEAR 2021 Gen2 Updated Version Level 1 EV Charger (110V, 16A, 25ft), Portable EVSE Home Electric Vehicle Charging Station (NEMA5-15 Plug) https://www.amazon.com/dp/B08RXZX8N...abc_6AQQ0Y9RPZTJSE3MR1QS?_encoding=UTF8&psc=1

This is the charger I just bought.

The charge rate is different but linear to the miles per hour you can achieve. For example, if you drive a lot of highway, you achieve 3 miles per kWh. If I drive a lot of city, you achieve 4 miles per kWh. We both plug in to the same charger (evse), but my car would charge at a rate that shows more miles per hour than yours because your car consumes more kWh. Make sense?

I wonder about this. 16A on a 20A circuit would be ok, but on a 15A circuit, issues will likely occur. National electrical codes recommend sustained loads be no more than 80% of the circuit rating. And EVSE generally don't know the rating of the circuit (it is not something that is communicated by standard electrical components).

My Bolt defaults to 8A on 120V circuits. It can be set to 12A, but if the circuit is shared, that could create problems. Regardless, it will never charge at higher than 12A on 120V. Not sure if similar restrictions apply on ID4, but there are some older TT30 (30A 120V) receptacles in the wild, at some RV parks. So theoretically, with a TT30 plug, the 16A would be safe, and Teslas can charge with the mobile cord and a TT30 plug, they probably charge at 24A (2.88kW).

The formula is V*A=W or V*A=W/1000 = kW.

So, 120V * 16A =1920W (1.92kW). In one hour, you would add just shy of 2 kWh to the pack, so if your efficiency is a bit north of 3 mi/kWh, then you would be adding 6 miles of range per hour.

Make sure the circuit you use is 20A, and don't use it away from home unless you are certain the circuit is 20A.

You can run the stock EVSE at 240V using an adapter. If you have a 240V receptacle in your garage, you can make an adapter to go from 5-15P to x-xR (6-15R, 6-20R, 14-30R, 14-50R, etc...)

That should get you 6mph of charge, as 120V to 240V effectively doubles your charging rate. The stock EVSE is ~3mph, running 10A @ 120V.

Doesn't really affect the situation, but an observation.... That Amazon one should not be pulling 16A with a 5-15P tip on it. It's fine if your circuit is wired with 12ga wire and a 20A breaker, but it should have a 5-20P end if it were truly designed for that. An EVSE with a 5-15 plug should pull no more than 12A continuous. This one is definitely not UL listed...

Anyway... Pics of the adapter I made a while back:

Also, an adapter like this would probably work with your MEGEAR EVSE to get it to do 16A @ 240V on a minimum 6-20 receptacle.

Agreeing with what @Enzo589 wrote, that is a figure I see L1 charging my i3 at 16 amps, which is unquestionably a more efficient vehicle. I don't think you'll ever see 6 miles an hour accumulation on the ID.4. You'll have to plug in your actual average efficiency, your miles per kWh, to come up with a realistic result.

DanM gets 7 MPH from his, with an adaptor to go to 240V

US ID.4 included EVSE charger

I'm with you though, why design for 120 when a universal design for 240 can be done for no added cost. I'm willing to sacrafice mine and have the necessary adapters, I'll test on Saturday. Curiosity got the best of me, so I gave this a try tonight. Total success on 240 volts - no magic smoke...

Several EV models support dual voltage, but the labels on these typically say 120V due to the 5-15 plug on them. More on the subject can be found here.

For many years, power supplies on PCs and servers have supported dual voltage. In the data center at my office, we moved and switched 10's of millions of dollars worth of servers to 240V by simply using different power sources and the correct power plugs (along the lines of this).

Why? To reduce power consumption from cooling equipment. Computers run cooler on 240V, because the watts consumed are the same whether the power is 120V or 240V, so at 120V, the Amps are higher to generate the necessary Watts needed to run the computer, and Amps generate the heat. It is why GM is using a switchable voltage solution on the upcoming Hummer, switching the pack to 800V alignment for charging, and 400V for operation. At the same Amps, with no additional heat, the kW are doubled.

It makes sense the VW mobile cord is dual voltage internally. Why? Because EU power standards are 230-240V. Likely, the unit is fitted with a cord that matches the region the car is being shipped to.

When I am plugged into a 110/120 volt @ 20 amp circuit I get 3 miles per hour charge when the present charge level is a 60%.

3 miles per hour but my Clippercreek is being installed at 8 a.m. in the morning.
