152 mile range when fully charged?

Wed Jan 03, 2018 3:45 am

I've had my 2017 Bolt EV Premier a little over a month, and it has 600 miles on it.

Right now, it is sitting in my closed-but-unheated garage plugged in. It says it is fully charged and that the range is 152 miles, only 64% of the claimed 238 miles. The car displays the ambient temperature as 45 F.

The energy screen says zero for other factors that affect range and -3.8 for outside temperature.
This seems like way more capacity loss than I would expect for this temperature. It seems like, if battery loses 1/3 of its capacity when the temperature drops to 45, it would become almost useless in really cold conditions.

Any ideas?

What was the ambient temp during charging?
-3.8 or 45?

It was never as low as 3.8. The -3.8 is the Outside temperature value shown on the Energy Usage Score page. See the attached photo. I don't know how cold it was in the garage while it was charging. It could have been as could as 20 or 25 F part of the time, but must have been 40 F or higher part of the time. However, I don't see how a low temperature while charging could decrease the amount of energy that would be available from the battery after it was warmer and still plugged in.

What mostly concerns me is the large decrease in range with a fairly modest decrease in ambient temperature.

There are quite a few "range question" posts (including temperature-specific issues) on this site. Your question(s) might already be answered.

In recent driving just before recharging, were you getting worse economy, commonly due to using the heater?

The bar graph of economy in 5 mile chunks may be a useful thing to look at.

Welcome to the real world of wintertime EV range.

We use hilltop charging and and at 20 degrees are seeing 140 miles or less.

If I read that virtual gauge correctly (and I'm not sure I do) then the climate control is responsible for a lot of the drop. The heating system always eats huge amounts of power in an EV in frigid temps.

The disadvantage to an EV is that you lose range. Sure, an ICE also loses range in cold weather, just not as drastically.

The advantage to an EV is that the car starts.

The car starts, provides full power, instant heat to the driver, and actually saves even more money on fuel costs in the winter. EVs have a lot going for them in the cold, but most people are just taken aback by the drop in range.
