Please let us know how they work out. I got Goodyear WeatherReady tires back in March at the tail end of winter. They are in a similar “winter-rated all-season” market niche. I only drove briefly in snow for a day while on a trip to Canada. They seemed to do well but I’ll have more experience...

FYI, I posted a somewhat related article today about the charging site status of another of the CEC grantees — EV Connect — which is building more DC charging along CA 99. EV Connect built DC chargers at 3 of 11 CEC grant sites; scrambles to add 6 more...

The “hold up the cable” issue with the Bolt is a mechanical issue with the motorized clamp at the top of the car inlet trying to grip onto the top of the cable plug. If the plug sags down at an angle then the lock mechanism isn’t able to grab ahold of the plug. The car notices this and reports...

I just wrote up a status report on the rollout of California sites versus the rest of the country. https://electricrevs.com/2019/06/13/with-over-200-sites-open-electrify-america-lags-behind-in-california/

I’m curious about whether it will be possible to successfully initiate a payment using the phone app on charging dispensers that are not succeeding with using a physical credit card.

Oops, sorry about misreading that. But, that implies that your 15 miles of driving was at slower city rates which wouldn’t necessarily warm the battery faster than 15 minutes of highway driving. So, yes, I still think it is quite likely a cold battery issue. I know you’ve been around the block...

Excellent update. Thanks!

See this document for details on how to set up OBD monitoring for the Bolt EV on an Android (or iOS) device: https://docs.google.com/spreadsheets/d/1sY5n8WFu52U6a4_mg3MdcGcmDk3scAP8_muSy-BlXPc/htmlview

Driving for only 15 minutes will have very little effect on the battery pack temperature, as noted in the article. You would have to drive at faster highway speeds like 70-75 mph (20+ kW output) for over an hour to really have much useful battery warming. It would help if the Bolt was able to...

It’s linked as a resource on the January 28, 2019 press release at: https://www.electrifyamerica.com/news-updates When it was first posted it on January 28 it had multiple errors. I pointed them out and they removed it. Then they fixed it and relinked it a couple of weeks ago and then it...

Here is the latest version of the Electrify America Cycle 1 map. It is a corrected version of a map that was first released in late January of 2019.

Very likely due to a cold battery. And remember, the battery temperature changes slowly so it might be 45F outside when you charge but the pack itself may be colder from spending the night at 30F or whatever. In any case, if you look at the graph in my article about cold weather charging you...

I believe the US 395 sites are still planned to be built and open by the end of this year. Electrify America recently released new Cycle 1 map artwork which omitted them along with several on US-101 on the northern CA coast. I believe those changes were an error and the map has since been...

I agree that some kind of user-initiated battery pack pre-heating might be a useful feature for speeding up fast charges during the winter. I wrote an article about these issues that includes a graph showing the Bolt’s DC charging rate at different pack temperatures. It also has a link to the...

That unit is the least powerful of ChargePoint’s set of new higher-powered charging equipment. Since it is only 156A it uses conventional charging cables. They have variations using the same dispenser unit but wiring it up either with another one nearby or with a charger cabinet that has...

The bus bars in the Bolt battery already handle 400A at least for awhile since the pack output is rated for a peak of 160 kW (400A @ 400V or something like that). I think the limitation on the car’s DC charging rate lies elsewhere.

I’ve got an article on the upgraded San Jose EVgo site: https://electricrevs.com/2019/01/20/evgo-opens-first-upgraded-200a-charging-site-in-san-jose/

Slight update: Change and Ollie are 150 kW Ivo is 175 kW and Janus is 350 kW

My guess is that 110A was due to cooler winter temperatures. For details see my article at: Frigidity and the challenge of high-power coupling https://electricrevs.com/2018/10/23/frigidity-and-the-challenge-of-high-power-coupling/
