However, I have not seen or heard of a single public AC charger in the US providing more than 7.2 kW per plug. With 3-phase (which is very common for the buildings the public chargers are at) it's limited to 16.6 kW and it would be impractical to get split-phase just for EV charging (DCFC would make more sense). Just to note that's with split-phase AC power. Is there a future for faster AC charging alongside the "sexy" DC fast charging infrastructure investments we're seeing the most of? Say, 19.2 kW AC chargers for that "happy medium" getting ~50 miles during lunch or while shopping in town? Are there any plans for this kind of L2 development from the likes of L2-focused companies like ChargePoint, or is everyone pretty much focused on keeping the 7.2 kW AC maximum?Īnd he mentioned a 19.2 kW AC onboard charger option. Most appear to be even lower, around 6.8, 6.6, and in some cases as little as 3.3 (6.6 per stall shared by two plugs). Assuming the Equinox EV gets roughly 3 mi/kWh, that's good for more than 50 miles of range per hour - more than double what even the most efficient EVs can get on typical 7.2 kW AC service.įor home installations, this is a novel feature. ![]() I was watching Alex on Auto's walkaround of the Equinox EV and he mentioned a 19.2 kW AC onboard charger option.
