Delivery Van Fleet Demand Charge Calculator

kVA billed demand and monthly demand charges for a delivery van fleet depot — plus what staggering saves.

One all-chargers-on moment sets your maximum-demand charge for the month — Indian HT tariffs bill ~₹450/kVA on the highest 30-minute interval. Last-mile vans are the easiest fleet to electrify: predictable ~120 km routes, depot parking every night, and 11 kW AC charging covers the day's energy in under 4 hours. Model worst-case concurrency below and see what a simple two-group stagger saves.

Annual demand cost₹738,947

Demand charges bill the single highest kVA interval of the month — one all-chargers-on moment sets the bill for 30 days. Load management software (or even a relay-based stagger) that halves concurrency roughly halves this line item.

Frequently asked questions

What are demand charges and why do they hit EV depots hard?+

Utilities bill your single highest demand interval of the month (kVA or kW) at a fixed rate — ₹200–600/kVA in India, $10–25/kW in the US. Chargers are big synchronized loads: one all-on moment at shift end can set a demand bill that exceeds the month's energy cost.

How much can load management actually save?+

Halving concurrency roughly halves the EV share of billed demand. For a 20×30 kW depot at ₹450/kVA, two-group staggering saves ~₹1.2 lakh monthly — recurring, forever. The stagger row computes your exact figure; payback on control hardware is typically weeks.

Does charging slower avoid demand charges?+

Charging at lower power across more hours cuts the peak directly — if the energy still fits your window (check the ToU scheduler tool). The optimal strategy is usually minimum power that completes by departure time, not maximum power on arrival.

Why does power factor appear in the Delivery Van Fleet Demand Charge Calculator?+

Indian HT tariffs bill kVA (apparent power) = kW ÷ PF. Modern chargers run PF 0.95+, but legacy site loads drag the meter's PF down and inflate billed demand. The PF input reflects your bill's reality; the PF-correction tools handle the fix.
