  "assumptions": {
    "home_basis": "EPA combined electricity use (kWh/100 miles) is measured from the AC wall, so home charging cost on these pages is that figure times the EIA residential price. No second loss factor is added.",
    "full_charge_basis": "A full charge is the wall energy implied by EPA combined consumption times the EPA combined range: kWh/100 miles × range ÷ 100. It is the energy to drive that rated range from empty, not a manufacturer usable-battery capacity.",
    "public_dc_fast_basis": "Public DC fast chargers typically bill energy delivered to the vehicle. These pages show plain EPA wall energy times the Paren price, and a rough estimate of delivered energy equal to that wall figure times 0.894. The 0.894 factor is mean Level 2 (240 V) AC charging efficiency from Sears, Roberts, and Glitman (2014), not a measurement of DC fast charging and not a test of these 2026 vehicles.",
    "level2_ac_efficiency": 0.894,

    "level2_source_url": "https://doi.org/10.1109/sustech.2014.7046253",
    "level2_finding": "Across 115 usable charges on two Nissan Leafs and two Chevrolet Volts in Vermont (June–November 2013), mean Level 2 efficiency was 89.4% and mean Level 1 efficiency was 83.8%.",
    "display_rounding": "kWh/100 miles is the EPA combE value rounded to 0.01 before any dollar math, so a reader can multiply the figure printed in the table. Dollars are rounded to the nearest cent at the end."
