L2 max EV charging speeds
I'm ashamed to admit something.
I just recently realized that EVs have max L2 charging speeds. I had just assumed max charging was limited to the DCFC max charging speed on all vehicles, but reality is vehicles have a max AC charging speed (L2) and a max DC charging speed (DCFC).
The simple reason for this is that cars have onboard power electronics that convert L2 AC power to DC and the max charging speed on L2 is going to be limited by whatever the auto OEM limits it to.
Prior to this realization, I was really excited about several manufacturers coming out with 80A chargers that would charge at 19.2 kW (on 240V). But as you can see from the above graphic, only 3 cars can charge at that speed, and really only one of them, the F-150 extended range will be sold at volume anytime soon.
Plug-in hybrids aren't listed on the above graphic but typically they have even slower charging speeds.
That doesn't mean that L2 80 A chargers don't serve a need in the marketplace, especially as more pickup truck EVs come on the market. And there are plenty of cars that charge over 7 kW that will still see value from a faster L2 charger.
Above graphic was compiled with the help of this link from Clipper Creek. If anyone has a good resource to clearly compare charging data for L2 and DCFC between multiple manufacturers I'd love to see it!

2 年Chris Kaiser While it is nice that some vehicles can charge faster and take more power from the wall. Have you found that the limitation is not on the vehicle, but on the electrical infrastructure of the building?

2 年Good info on the vehicles available in June 2022. However, when planning EV charging infrastructure, it's important to consider both current and future needs. Certainly, it won't help to install a 19 kW charger for most of today's vehicles. That said, the largest part of the cost for most charger deployments will be for the electrical improvements. While it makes sense to install lower power chargers for your current vehicles, you may want to consider installing wiring sized for you future needs. Then you would only need to replace your charger and circuit breaker.
