I don't drive that frequently during the week because work, stores, and virtually everything I need is within a bike ride distance from home, but I do go on long road trips on the weekends.
I'm fairly new to the process of learning about Bolts, so please forgive me for my ignorance. Is there a cost involved in using the charging stations at grocery stores, the libraries, and whatnot, or do you use them for free? They are all over my neighborhood but I've never inspected one or closely watched someone plugging in.
Approximately, where are you located?
Plugshare rocks! If you filter on the web site and via their app, you want to filter by J1772/EV Plug for level 2 AC charging and SAE Combo for DC charging, usually fast. Plugshare is crowdsourced so the pricing info may not be accurate. Using pricing info on web site and app of other networks (e.g. ChargePoint,. EVgo, etc.) will be more accurate.
There are VERY few DC fast chargers in the SF Bay Area. Free also often means busy. And, they could be broken or blocked. There are some free level 2 charging stations but I don't recommend going that route unless they're convenient and you plan to be there for many hours on end anyway.
Almost all of my charging is for free at work. I've never used the DC FC portion on my Bolt yet (got it at end of Jan 2019). My other EV, a '13 Leaf SV w/premium w/NO DC fast charging inlet was my primary car from July 2015 until recently. My previous '13 Leaf had CHAdeMO (another DC FC standard) but I used that portion of its port ~16 times in 2 years on free DC FCs. None of those are free any longer.
Paid public charging is almost always going to be more $ than charging at home.
I used to use some free public L2 charging near home on Fridays and weekends w/my Leaf but I don't really do so for my Bolt. Don't need it.
I normally would not recommend a non-Tesla pure EV to anyone if they cannot charge at home, work or some places where they're going to be at regularly for many hours at a time.
Even w/Teslas, thanks to their excellent Supercharger network, it's going to be costly to use those.
