Charging time and EV range decrease

Was your EV range down to zero before you began charging? The range down to 25 miles on display and 20 miles actual do not seem so bad, but I don't know about the charge time. I have never paid much attention on charge time to completion.

 

if the battery is accepting less electrons, maybe the time decreases proportionately.

are you preconditioning?

 

Is 4 hours to full charge, actual time it takes to fully charge the traction battery, or is it the display you see on MID when you plug-in. TBH, I have never actually checked actual time on mine. Mine is always get charged overnight while I am in bed. The question is, is it really taking shorter time to fully charge the battery or it's just displaying shorter time than actual?

 

Oh, you have an Advanced trim. If it is really taking shorter time to fully charge, then next question is do you know how much kwh get used at wall for full charge? If you are using L1 EVSE that came with the car, easiest way to check is to use kill-a-watt meter to take a measurement for zero EV to full charge. It normally takes 6.3-6.7 kwh to fully charge for mine. If it is really taking less charge, then this number should be something like 5.2 kwh.

 

You can pick it up at any hardware store like HomeDepot or Walmart or online Amazon. Cost about $25.

cold weather reduces the batteries charging capacity. preconditioning is heating or cooling the battery before and during charging to aid in capacity during temperature extremes. you can find it in the owners manual, or many threads here.

 

Preconditioning use traction battery, so it could reduced the range, but it will not explain the reduced time required for a full charge. It should increase the time instead.

 

it might make your capacity increase a bit, i'm not sure.
