EV Taxi Fleet Charging Cost Calculator

Monthly charging cost, per-vehicle and per-km energy cost for a ev taxi fleet on Indian ToU tariffs.

Taxis run 250+ km/day and can't afford daytime charging downtime — split charging between a cheap overnight base charge and short opportunity top-ups. This calculator blends your peak/normal/off-peak charging shares into an effective ₹/kWh, then rolls it up to monthly fleet cost and energy cost per km — the number ride-hail and taxi fleet owners quote against diesel.

Blended rate = Σ(share × window rate). The savings lever is the off-peak share — every 10 points shifted from normal to off-peak hours cuts the bill by the spread between those windows. Demand charges are separate; see the demand-charge tool.

Frequently asked questions

How much does it cost to charge an electric fleet?+

Fleet energy (vehicles × kWh/day × days) priced at your blended tariff. The blend is the lever: the same fleet costs 30–50% less charged off-peak than at evening-peak rates. This calculator computes the blend from your window shares so the bill stops being a surprise.

What is energy cost per km for EVs versus diesel?+

EV: Wh/km × tariff ÷ 1000 — typically ₹0.8–1.5/km for cars and LCVs on off-peak power. Diesel equivalents run ₹4–8/km. The 3–6× gap is the electrification business case; this tool gives your fleet's exact figure for the board deck.

Should fleet charging avoid peak hours entirely?+

Almost: peak-window rates run 30–80% above off-peak, so every kWh moved out of peak is pure savings with zero hardware. Keep a small peak allowance for operational top-ups, and let the scheduler tool check whether your full fleet physically fits in the cheap window.

Do demand charges appear in the EV Taxi Fleet Charging Cost Calculator?+

No — they're a separate billing line based on your peak kVA, covered by the dedicated demand-charge tools. Energy (this tool) plus demand (that one) gives the full bill picture; for DC-fast-charging depots the demand line can be the bigger of the two.
