Home charging using 220v

[Keapana]

Just wondering about other people's experience with charging I'm using a home charger actually using our Tesla cable plugged into our extra 220v outlet with an lectron adapter. My wife's model 3 charges at 24-25 miles per hour. My new lightning I'm only getting about 13 miles per hour can anybody tell me if I'm doing something wrong or how to increase the miles per charge time

Depends on what Amperage is available via your EVSE.

Miles per hour is a horrible way to measure charge rate. What is the KW rate for each?

The battery in your truck could be twice the size as a model 3, if so, it will take twice as long to gain the same %SoC.

Miles/hour is a highly-variable metric. What's the kW rate?

depending upon the model and available charging infrastructure, our Lightnings can Level 2 charge at up to 80A/19.2kW. You’re not getting those L2 charge rates on a Model 3. With that said, you don’t need them because the Model 3 battery is smaller and it’s more efficient. As others have said, focus on state of charge and energy added, not miles.

Actually, 2024 Lightning's can only charge at 48A. So the max charging he'll see will be around 10kW at 220V.

Those numbers sound exactly right

A Tesla should get ~4 miles/kilowatt hr, while the rolling brick we call our truck gets ~2 miles/kilowatt hr.

Thus, a Tesla can go twice as far as a lightning using the same amount of energy.

If you’re charging at 6 kilowatt hours, then a Tesla should get ~24miles/hour, while a lightning should get ~12 miles/hour.

Yeah numbers make sense, trucks get less mileage than cars.

As others have noted, miles per hour is not a measure you should use. The real question here is what's the amperage of the Tesla charger? Tesla's allow you to control the power you pull, the Lightning does not - it will pull the max offered. So, what's your charger set to?

On Kauai, I would expect you're not doing a lot of hours long high speed driving. What does your trip odometer show as your Trip 1 or Trip 2 miles per kWh average? I'll bet it's high. So, now you can do the math - 13 / that average = kW you are receiving from the charger.

He has a 2024. Max charge rate is 11.2 KW.

I use a CP Home Flex. Charge nightly 4-5 hours at 240 V & 9+ kWh. Puts 30+ to 40+ kWh back in truck which is my daily use (Summer v. Winter) and easily covers my 100 mile daily commute. The Home Flex can be set up to 80 amps but that requires upgrading the service line from 8 AWG copper to 6 AWG as I vaguely recall. I’m just cheap for now. Power is $.063/kWh so that’s like ridiculous low cost.

I think 80 amps sustained needs a 3 AWG line. That is likely over $1 / foot cost for THHN copper installation. 6 AWG might be sufficient for the Ground.

When I installed mine, #3 copper was $1.59. I ran #1 aluminum ($0.59 per foot) the first 90’ to my disconnect, then copper the last 3’. The EGC can be #8.

This post made me go hug my 2023. I did not kiss the 100 amp breaker, though.

But it likes you to kiss it, it loves to give you the tingles….
