Re: Chevrolet Bolt - 60 kWh, 238 mi, < 7s 0-60

Tue Oct 23, 2018 4:51 pm

I've posted a lengthy review of our experience with the Chevy Bolt.

"In short, we are pleased with the car. It works well for us and in the process has become our sole vehicle. We no longer operate a car with an internal combustion engine. In those circumstances where the Bolt won't meet our needs, we plan to rent a conventional car. Importantly, we haven't had to do so yet."

Driving the Chevy Bolt EV--Our Impressions
September 28, 2018, by Paul Gipe

We leased a Chevy Bolt EV in early November 2017. I've been driving the electric vehicle daily since then. We've also taken it on several round-trip excursions of 300 to 600 miles. I know enough...[more]

Paul, thanks for providing a link to this. I meant to ask you to do so or copy it here, but got busy and forgot.

Chevy Bolt EV Survey Hints At Cold Weather Package With Heat Pump
https://insideevs.com/chevy-bolt-ev-cold-weather-package-range/

Earlier this week, new Chevy Bolt EV owner and chevybolt.org user jvandonsel posted about a survey he received from Chevrolet. The options presented in the survey hinted that a cold weather package might be in the works:

I just took an interesting survey from Chevy asking about cold-weather performance of the Bolt and how much I’d be willing to pay for various cold weather packages.

What’s interesting is that this is a peek into some of the technologies that GM is working on or considering working on. Some of the interesting ones from the survey are:

Radiant floor heating
Wiper parking heater
Heat pump
Cold weather battery pack
Heated front windshield

Having only owned my Bolt for a month, I didn’t have much wisdom to impart, but it will be interesting to see how it makes it through its first New England winter. . . .

The survey, which another user posted, also lists heated steering wheels and seats as well as 200 and 300 mile EPA range and varying winter ranges of 150, 160, 195, 240 and 285 miles, as well as various combo packages including more than one of the options, with prices. None of these are guaranteed to appear, although the article notes that a survey last year included a variable charge level, which has now shown up on the 2019s.

The Bolt already offers heated seats and steering wheel as park of a cold weather package.

Erm,..."wiper parking heater"??? As for heating all of most of the floor, that's just silly. Heated pads under the footwells would be nice, though.

I've got that on my Forester, although it's not called that. It's a electric wire or two embedded at the base of the windshield, so that you don't have to worry about your wiper blades being frozen to the glass and tearing off, or burning out the wiper motor, and also keeps slush from re-freezing there. I got used to parking my wipers off the glass in cold conditions long before such conveniences were available, and need to do so rarely as I don't live in snow country, so it doesn't do me much good, but I wanted the heated outside mirrors (beats having to use de-icer and a scraper on them, and it's also nice in wet fog) and heated front seats that were also part of that package.

This Chevrolet Bolt Battery Lost 8% Capacity At 70,000 Miles
https://insideevs.com/chevrolet-bolt-battery-lost-capacity-70000-miles/

Haven't watched the video, but the author says the following:

“After 70,000 miles, I decided to review the data that I have gathered for nearly two years of driving the Bolt EV. Based on my estimates, my Bolt EV has lost a noticeable amount of battery capacity. To estimate the amount of degradation, I compared kWh used versus the battery percentage displayed at the station, and I was able to create a timeline of total estimated battery capacity.

0:47 Methodology

3:41 Degradation

4:44 Software Update affected capacity?

7:45 What can other EV owners expect?

9:30 Does DC fast charging contribute?

10:35 Does that much degradation actually matter?

13:03 My Recommendations

15:04 Closing”

Thank you for a wonderful write up on the Bolt.

Being that you are in this field of evaluation electric vehicles, would you have any information on the expected lifetime of the Bolt battery before needing to face a battery replacement?

It appears that when choosing an EV nowadays, consumers need to take into account the size and durability of the battery more than anything??

Thanks

News Coulomb has a video as he is at 70,000 in his bolt and by his estimation he has lost 8%. I think my leaf is in pretty good shape and at 70,000 miles I was down 18%

The Bolt has about 3 times the battery size. So on a miles traveled per battery consumed basis, your LEAF is doing better.
