I'm confused about the "monthly membership fee." I currently have an EvGo account active, for when I'm in a pinch and need to pay significantly more for electrons than I do normally, but I do not pay a monthly fee. And the page has aero details about it outside the headline, a clear example of an unhelpful content experience.
It's pretty simple: EVGO has a two tiered system. Your "free" account has higher per minute rates, stricter time limits, and no free minutes of charging. The monthly plan, currently $7.99/mo, gives a discount on the per minute charging rate, looser charging time limits, and 29 included minutes of charging per month.
Which one works depends on the frequency of usage. The "free" account is best for ad-hoc occasional charging while essentially the 29 included minutes in the monthly plan covers the $7.99 fee, so if someone charges at minimum once a month regularly at EVGO, then it's likely worth getting the monthly plan.
The point is AAA is offering their members all of the benefits of the monthly plan without the costs. So if someone is a AAA member, then it's a pretty good deal.
