EV charge getting worse

Charger and car sound fine. The range is based on how the car is used so it can fluctuate a lot. I live in NY as well, yes the cold will use up charge quicker. Best mileage will be like Spring/Fall when it's like 60 degrees, no heat or AC, no lights, wipers, rain, uphills or high speeds, etc...

 

You put energy into the battery, not miles. How far you go on that energy depends on lots of stuff like traffic, speed, temperature, climate control, terrain, wind speed & direction, etc.

Also, the charger is in the car. What you bought is an Electric Vehicle Supply Equipment (EVSE), more commonly called a charging cable.The brand, speed, and source of EVSE you have is completely irrelevant as long as it's functional.

 

While a low temperature will have a temporary affect on the battery capacity,
AGE has an permanent affect......and will gradually get worse.

Maybe 3 hours isn't enough charging time ? Just a wild guess.

 

13.6 was the last owners range based on their driving and environment.
it could even be factory default if the 12v ws disconnected.
what you're seeing is projected range based on past history, just like dte for the gas engine.
cold has a major effect on the range (battery capacity, friction losses and etc.)
i'm doen to 11. 5 from 14 in the fall, and it will go back up in the spring, then down a bit in summer due to heat, humidity and a/c use.

 

The miles shown are based on how/when you used the EV mode averaged over a number of trips, not the amount of battery charge. If you go up many hills the value will be lower. If you just use EV on the flat or downhill the value will be larger. They way I use my EV mode my 10 year old battery "shows" 12 or more miles. I live on a hill and always use ECO mode going home and EV mode when leaving.
