‘22 MYP charging rate way off

6-20 Nema garage outlet. Supposed to be charging at 14-15 miles per hour, but it’s charging at 5 miles per hour.

I just picked up the ‘22 MYP today and this is the very first time charging at home.

The reason I ask is I’m coming from a ‘21 MY LR and it took a lot less time.

At 28% I have 86 miles left. 15 miles per hour @ 16 hours = 240 miles. 240 + 86 = 326 miles

That can’t be right @ 80%? It’s charging 4 1/2 hours longer than it should.

Is the battery pretty cold? It could be just heating the battery with that 4kw for the first 10-20 minutes of charge

Phew! I had to log out of the app, unplug the charger from the vehicle and do a hard boot. Back in business!

What happened to your 2021 LRMY, did you wife steal it from you?

The Tesla Model Y charging algorithm will continuously update the time needed to complete charging. The Tesla charging screen in the screen shot showing 4kW +1kWh 16A/16A and 238V means everything is as it should be for charging using the 20A 240V circuit. The Tesla is charging at 16A out of 16A maximum for the circuit.

Sold it for $64k @ 10k miles to a west coast dealership

At 3.5 KW (what your battery is getting) it would take 22 hours to go from 0% SOC to 100% SOC, you are going from 28% to 80%, so your amount charged is 52%... 52% of 22 hours is about 11.5 hours, but your car's estimate is a bit over 16 hours... I suspect that the cars estimate is off rather than the actual charging speed being a problem... the only other possibility I see is you have an unheated garage in sub zero temperatures.

<edit> looks like you reset it and it was a "computer confused" problem... glad it is resolved, enjoy the MYP </edit>

I’ll keep an eye
