Energy Cost Per Km: Electric runs at ₹0.80 to ₹1.20 / km compared to ₹5.50 to ₹7.50 / km for diesel cargo vehicles.
Maintenance Savings: 40%–60% lower maintenance due to fewer moving parts (no engine oil, filters, spark plugs, or clutch plates).
Payback of EV Price Premium: Typically achieved within 14 to 20 months of active commercial duty.
Formula
Annual Energy Cost = (Daily Km × 365 × Rate Per Unit / Km Per kWh) Annual Diesel Cost = (Daily Km × 365 × Diesel Price / Diesel Mileage) 5-Year Total Savings = Fleet Size × [(Diesel Fuel + Maint) − (EV Power + Maint)] × 5 Years
