Fast chargers: over-rated?

Many assume that adoption of light-duty electrical vehicles (EV) will be limited until EVs recharge as fast as combustion vehicles refuel at a gas station. That’s not quite true. The truth will not surprise many EV drivers, but (warning!) some combustion vehicle drivers might be shocked

When I'm driving more than typical daily trips in my EV, I find that moreso than Level 3 vs. Level 2 chargers, what I most want is conveniently located chargers: right off my main highway corridors and co-located in desireable spots: at restaurants where I can combine my charging needs with a mid-roadtrip meal or with useful shopping locations like a grocery store or department store that allows me to stock up and kill two birds with one stone. The worst are when the only EV chargers found are off the beaten path and near nothing really useful for a road tripper, like on a car dealership lot.

Matt, I do not quite understand your comment. Do you use L3 or L2 more?

Some of the new Fast Chargers placed by court order under the Electrify America name are not very reliable. Some are city chargers rated at 150 kW but most post they only get about 50 kW. Others are set for 350 kW but most EVs can't take that much. My very affordable Chevy Bolt EV can only take 55 kW. So they are good for a 30 to 1 hour charge but also cost about the same as a gas fill up. 

    So I like a good Level 2 charger. One that can provide 11 kW is fast enough but most only provide 6 kW. That let me shop or eat without having to hurry when I am around town. On a rare longer trip everyone like the most speed at the fastest chargers. They are getting better just like the vehicles. The new trucks may keep a lot of charging spots busy for many hours. This Holiday time has lines at many chargers.

Destination charging is usually the best. 

Overall, reliability is bad, although some do better than others, based on my data (in Canada, I haven’t look at the US).
