Was able to charge to 279 now can only get to 235.

2020 Bolt EV. Before- I could charge to max rate of 279 miles (307 tops). My kid borrowed the car and now I can only charge to 235. Battery flow shows all full. Any ideas what he could've changed? Thanks in advance.

For a deep dive, take a look at this video.

Hahahaha on the tariffs. And yes, it's the temperature affecting the mileage. (Up here in the cold northeast my 80%-full range has dropped from 195m to 150.)

Hahaha on the tariffs. And yes, it's the temperature that's primarily affecting your mileage - up here in the cold northeast my 80%-full range has dropped from 195 miles to 148.

2019 Bolt Premium with 50,000 miles, a pair of Cadillac roof cross-bars, a single Thule bike channel, and a homebrew spare tire with a jack and tools. The air friction from the roof and the spare tire lit has no measurable effect on my range. ( new propulsion battery was installed with 36k miles on the original battery )

Range displayed above 260 miles is only while the car is standing still or initial (after disconnect) moving in best conditions on level roads for a short period and then the range readjusts to reality.

I'm in southeastern Pennsylvania and drive to/from Baltimore on occasion using i95.

Averaging 80 mph on i95, I get 215 miles 8 months of the year, and 145 miles in the dead of winter. These numbers take into account my turning on and off the heating and cooling manually.

Worth noting is that extreme temperatures also make for longer charging time.

Your range is incredibly low. Perhaps it is your Mario Andretti driving style? I always get at least 260 miles per charge in a temperate climate. I wonder what kind of range you would get at 65 mph. The bolt is not very aerodynamically advanced compared to other cars, so driving 80 would tend to make the range plummet.

I have never in 8 years seen a full range of 279 mi. In order to get that higher range he would have had to have driven 30 miles per hour or slower the entire time he had your car. 279 on a 60 kilowatt battery he'd have to have his kwh/mi display at 4.6
Normally your kilowatt to mile display should read 3.9. all I can think of is he spent the entire time in the slowpoke Lane

Re: temperature. Since the fall, I've been recording my charging data and odometer readings. I generally drive about 40 off highway and 55 on highway

At 70 deg, my car consumes about 13kWh to go 60 miles
At 50 deg, it's about 22kWh
At 40 deg, it's about 29kWh

So, at around 40 degrees, I get about half the range as at 70 degrees.

So I'm on my third bolt (currently a 2018 with the 65KW swap) Not to be combative, but I routinely get over 4.5 Kwh/mi, mostly around town driving but commute 15 miles each way in the am and evening. Temperature this winter severely decreased and yes I pay close attention to how I drive it, so trying to optimize but I've seen the range meter go significantly over 300 miles. (have pics if there are doubts) Highway drives it down to 4 miles per/kw

My point exactly.

This just in from my dealer. Things I did not know:

1. Charge Regularly: Aim to keep your battery charged between 20% and 80% for optimal battery health. Frequent full charges can decrease battery lifespan.
2. Use Level 2 Chargers: Whenever possible, use a Level 2 home charger or public charging station to speed up your charging process.
3. Plan Your Routes: Utilize charging apps to find nearby charging stations along your route, especially for longer trips.
4. Avoid Extreme Temperatures: If possible, park your EV in a garage during extreme weather. Both hot and cold temperatures can impact battery performance
