The issue isn't really build more charging stations...at this time. (I am not saying we do not need more....) The issue arises only at Electrify America stations that I have seen (West Coast US).
That is because a lot of manufacturers have included 1-3 years of inclusive charging at EA. If an EA is full, you can go to a ChargePoint around the corner and there might be one other vehicle charging there. There have been plenty of open charging spots whenever I have looked for them, just as there is usually a Queue at most of the EA stations, at least in southern California.
Makes me laugh a bit. I will see a 100k Mercedes waiting in a Queue at an EA and have seen fights occur over an EA spot. Some people are very self absorbed and apparently do not have any consideration of others.
And all along, for about $25 dollars they could have gone another block or two and not waited and avoid the aggravation.
I have had 3 i3's (still have one) since 2016. I bought my i4 in March 2023 and travel around California quite a bit and I have NEVER had to wait for a charger.
Unless I am at an EA Station - then I choose if I want to wait or not. Twice I have waited for about 5 minute's. Any longer than that and it is not worth my time to wait.
Another issue is that EA does not properly maintain their sights in a timely fashion. It takes months at certain locations for them to repair a non-functioning station. I figure this is down to not enough techs that know how to fix these at the moment.
Before manufacturers starting 'Including' charging with new purchases, there was not a queue for a station - not once. I imagine when the term runs out for the included charging for these vehicles, no-one will go to an EA as ChargePoint is just better. And less expensive as it goes.
