Summary of 3/28/26 TEVA Meetup

[Rob]

Thanks to the 10 EVs that showed up for coffee, donuts and some EV related chatter! Good times. Here are a few pics Len captured:

 suggest we do something like this monthly, perhaps on the second Saturday of the month. We scoped out the parking area near the Udall Center/Senior Center which is quieter (less TV traffic noise) and more solar canopy parking spots. It was pretty crowded at 11AM, but there should be plenty of spots for us at 7-8AM before crowds arrive. People seemed a little less hurried in the area, so maybe more likely to stop and talk?

One of the topics we discussed was the growth of non-Tesla public charging. I started tracking the progress in 2021 for the Co Springs EV Club newsletter, so the following chart shows growth in the past ~5 years. 

Interesting to note how public AC charging is decidedly more common for non-Tesla chargers (about 93% are J1772 plugs). I would venture to guess that this number is flipped at Hotel locations given Tesla’s early push to install AC Destination chargers at hotels.

On the DCFC side, in recent months the non-Tesla networks have caught up to, or exceeded the number of Tesla plugs, and site wise there are over 4 times as many non-Tesla sites. However, if you consider the average number of plugs per site, Tesla is around 12 plugs per site, and others are 2.6 plugs per site (and slowly growing). 

I include this chart in my “Car Show Book” along with Plugshare maps showing public chargers in the state. It has been helpful in some conversations when folks argue there just aren’t enough public EV chargers, clearly in the past 5 years, roughly 3 times as many DC charging plugs, and twice as many AC charging plugs demonstrates the tremendous progress.
