Notes: Level 1 charge time assumes a rate of 1–2 kW, Level 2 assumes a rate between 3–10 kW, and DC Fast Charging assumes a charging rate between 11–90 kW. The vehicle efficiencies used are 290 Wh/mile for the PHEV10, 360 Wh/mile for the PHEV40, and 340 Wh/mile for the BEV100. (EPA fuel economy label values for the Toyota Prius Plug-in Hybrid, Chevrolet Volt, and Nissan LEAF, respectively.) Source: Electric Power Research Institute calculation.
