Miles per hour reading during charge

[petersk]

I went to a supercharge station with my model 3 and the car readout showed a charge rate of miles per hour. But when I charge at home, I do not get the same read out. Am I imagining this? If not, how do I get the same home charger readout to be the same as at the supercharger station?

I think it should be the same. If I remember correctly, when you have your charge level setting (the battery symbol) set to distance then charge rates show MPH, but if you have it set to energy, then the battery shows % and charging rates will show in kW. It has been a few weeks since I've supercharged though, so my memory is a bit fuzzy.

Where's the setting to change the battery symbol to distance instead of percent?

I can't remember off the top of my head. Go to the settings screen and try Display settings and then tap the gear icon on the top right for advanced settings. It is in one of those menus under advanced settings.

The touchscreen display for Supercharging (DC) is different than Home or L2 Charging (AC).

Supercharging (DC) shows:

• kW Rate
• mi/hr or ki/h
• kWh Added

Home or L2 Charging (AC) shows:

• kW Rate OR mi/hr or km/h
• kWh Added
• Current/Limit Amperage
• AC Voltage

Both my car and app show the miles/hour being added when I'm charging at home. Not sure why yours wouldn't. It's pretty prominent in the lower left corner of the touchscreen. In the app I think you have to go into the CHARGING screen to see it.

Nope, it's one or the other. He was right, I had to go to the "DISPLAY" setting and change it from energy to miles. The other interesting thing is that it doesn't deliver the promised 30 mi/hr charge rate on my 50 A 240 V circuit. It has only reached a max of 27 mi/hr.

On my HPWC at the cabin feeding the 48 amp AC charger onboard the Model 3 I get upwards of 45 MPH charging. When I am at the house where I use the 32 amp UMC instead off a 50 amp NEMA 14-50 I think the best I have seen is 31 MPH. I just started charging that way to see what I get currently. Pun intended. I am getting 244 volts at the 14-50 and 32 amps that the UMC is designed for. After a few minutes, it has gone from 26 MPH to now 30 MPH. You do have to wait for it to settle down.

Update: Took a while, but it is finally at 31 MPH charging

For as long as I could watch mine, it only got up to 28 MPH.

That's not right. What's your amperage showing?

My HPWC does 48a @ 240-246v on a 60a circuit and I get 45-46mph charge rate.

Amps * Volts = Watts
Watts / 247Wh/mi = rated charge rate in MPH

16 amps @ 208 volts = 13 MPH
16 amps @ 240 volts = 16 MPH
24 amps @ 208 volts = 20 MPH
24 amps @ 240 volts = 23 MPH
32 amps @ 208 volts = 27 MPH
32 amps @ 240 volts = 31 MPH
40 amps @ 208 volts = 33 MPH
40 amps @ 240 volts = 39 MPH
48 amps @ 208 volts = 40 MPH
48 amps @ 240 volts = 47 MPH

Your results may vary based on actual voltage. Also note that the displayed MPH rate is an average for the charging session.

So at work my Tesla is now only getting 22 MPH from the same chargers that used to be 30 MPH.

Others seem to be getting 30 MPH. App shows charging at 30 Amps and 194 volts. Any reason why the volt has decreased for me and is charging slowly?

Charger is a SemaConnect and I am using the Tesla adapter. Not sure if something maybe wrong with my battery or charging adapter.
