I have a Level 2 charger at home and regularly charge my Tesla with it, getting around 14 miles of range per hour. Today, I tried charging our newly purchased EV6 for the first time, but it’s only charging at Level 1 speeds—about 4-5 miles per hour. Any ideas on how to get it to charge faster like my Tesla? Thanks in advance!
Charging speed is measured in kilowatts, not miles per hour of range. What kind of EVSE (charging equipment) are you using, and what charging rate (kW) do both cars report?

I think OP means ‘miles of range added per hour of charging.’ While it’s non-standard, it can make sense as a comparison.

It’s not the best unit for this because miles per kWh varies with driving conditions, weather, and car type. Battery stores kWh, so kW charging rate is more consistent for comparison.

Also, the displayed range gain is based on recent driving, not what’s coming up.
@jessicah
The miles shown depend on past driving; the actual range you get depends on future driving conditions.

Doesn’t Tesla’s range display also inflate numbers a bit?
@jeff
Tesla calculates range per hour based on EPA efficiency, which can be high compared to real driving—especially on highways. So yes, that’s likely what you’re noticing.
Check the charging speed settings in your EV6’s options. Sometimes dealers limit charging speed for some reason.
Check the EV settings on your Kia’s menu. Make sure the car isn’t throttling the current. Also, check the charger itself to confirm what it’s set to and actually providing. Getting only 4-5 miles of range per hour on the EV6 could mean it’s charging at about 1.5 kW—either a low setting on the car or the charger.
We could use more info to help out:
-
Where are you located? US users typically deal with NACS and J1772 connectors, while outside the US it might be Type 2 AC.
-
Are you using the same charger for both the Tesla and EV6?
-
What’s the brand/model of your charger? If you’re using an adapter for the EV6, it could be a low-quality one affecting speed.
Charging rate depends on the amperage of your circuit. If you’re on a 50A circuit, you can safely charge at 40A. Check the charger settings for amps—you should be seeing around 10% battery added per hour.
Agree with others: knowing the kW rate is key.
Is this the same charger you use for the Tesla? Are you using an adapter for the EV6? If so, what’s the adapter’s rating?
Check the EV charging speed setting in the car’s settings menu. I had mine set to only charge at 60% of my charger’s max speed by default.

Could you share a screenshot of that setting? Thanks!
