Level 1 and 2 charging is for your home, there’s level 1 granny charger which is basically a regular power point into an adapter (like a laptop charger) which gets around 2.2kw, level 2 requires a level 2 charger to be installed in your house (usually in the garage or driveway) which takes the charging speed up to 7kW (single-phase) and 22kW (three-phase) but I believe most American homes are single phase.
Then you go into proper EV fast chargers (level 3) that are outside:
If you’re charging at home generally it’s overnight while you’re asleep or during the day from solar when you don’t need to drive (like on the weekend) or if you do need to drive you take it out and come back and plug it in so there’s no real issue there.
Here is a map of how many level three fast chargers are available in each US state.
Let’s use Texas as an example here. There are 243 fast chargers in an area of 695,662km2. That’s 1 charger for every 2862 km2. Not great coverage.
That’s not nearly so helpful so let’s take a look at the distribution with each state:
You can see that most of these EV stations are located around larger metropolitan areas. If you live outside of those areas, electric cars are not really, very useful. That graphic, even though this is from 2022 that the metric is there a three times more gas stations, per capita than there are chargers.
Here is just Teslas Supercharger network. Noticed that it’s much smaller and only really works for Teslas.
Here is the map showing which of these locations allow for non-Tesla partners electric vehicle charging. There are less sites that I allow you to charge a non-Tesla vehicle.
And here is the map for others that are not partners and not part of Tesla supercharger network. There are even fewer sites that allow other cars to use the supercharger network.
So all of this is great if you own a Tesla, but if you don’t, there’s competing standards and EV Charging stations may not be compatible with your car.
You’re close but slightly off
