In some current movies, Out of Spec examined Electrify America stations within the current chilly climate. What they discovered was that some native stations didn’t work in zero diploma (F) temperatures.
It’s price noting that on the identical location, the older station design (with the lone CHAdeMO plug) nonetheless labored, so it’s not a web site outage. So, Out of Spec’s group assumed that the brand new stations don’t work in excessive chilly. (Should you’re from Canada or Alaska and suppose zero levels (F) isn’t excessive, remember that I’m a desert dweller and the worst I’ve ever seen is about -5 F)
Kyle went out this morning and located the identical stations working once more, and in temperatures simply above freezing.
Replace! Now that it’s ticked above freezing (34F) the EA BTC items are again to working.

So, he assumes, there have to be a temperature between zero levels and freezing the place the chargers fail, and he needs to resolve it.
This Isn’t A Common Downside
I did a few of my very own digging round on Plugshare and located that this expertise wasn’t common. New Electrify America stations in Texas, the place in addition they obtained some very low temperatures, appeared to work by means of the Arctic blast, even when their speeds have been a bit of sluggish (which can have extra to do with automobiles than stations in lots of instances).
For instance, new stations in San Antonio, Texas, have been nonetheless working even in freezing climate. One Plugshare person warned others about what he had seen on Out of Spec, however others stated it was working high quality. Trying elsewhere, I discovered a station in Waco that appeared to be working high quality regardless of the chilly temperatures. So, the belief that every one of Electrify America’s newest era stations can’t deal with the chilly doesn’t appear to carry water.
However, Out of Spec had already come throughout this.
Excellent news! A number of stories of SK Signet variations of those new chargers working nice. The primary concern appears to be with the BTC variants. They appear the identical however every has a label on the aspect denoting which producer. https://t.co/sbbAI0PlqP

The problem is that not all of Electrify America’s new stations are the identical. They’re equivalent on the surface, however could be made by completely different producers. The BTC Energy stations appear to carry out poorly in sub-freezing temperatures, whereas those made by SK Signet look like holding up. This provides an additional layer of complexity to the puzzle.
I used to be in a position to determine that the station in Waco, Texas, is an SK Signet unit, so this concept (that BTC Energy items are the one ones affected) could also be true. However, it’s vital to notice that at this level, we’re working with only some samples.
Different Issues That May Be Inflicting This
After we’re solely working with a couple of stations throughout the nation, it’s laborious to give you a definitive rationalization. Whereas it seems that stations by completely different producers are higher or worse within the chilly temperatures we’re seeing, it might virtually simply as simply be a coincidence with such restricted data. Different issues might nonetheless be at play right here.
One chance is that native utilities might be struggling in some areas greater than others. This might result in voltage sags that take EV charging stations down. The charging station would possibly even seem to work after which run into issues after it tries to start out charging on this case. Minor variations between completely different producers and even batches might mix with utility points to create very tough to foretell or resolve issues.
One other chance is that the problem isn’t with a selected producer, however solely with sure stations from a given producer. One provider is likely to be offering a cold-vulnerable half, or one batch of the stations from the producer may need issues right here.
So, the most effective factor we will most likely do at this level is wait and see what folks can study within the coming days and weeks. I’ll even be reaching out to Electrify America to see what they find out about this, however on condition that it’s a vacation, it might take days to listen to again from them.
