The previous-generation Kia Niro was one of those compliance EVs, built from an existing gasoline-powered model and not quite optimized for the modern world. The Kias and Hyundais on the fast-charge list are all built with modern 800-volt architecture, but the old Niro didn’t have that advantage, and thus is pretty darn slow. Its 64 kWh battery charged from 10 to 90 percent in 65 minutes, peaking out at 74 kW and averaging 52 kW. It’s bad, but it’s not as bad as the rest of the cars on this list.
