Question 1

Is EV fleet maintenance actually cheaper than diesel in India?

Accepted Answer

Yes, and the gap is large. WRI India's model shows ₹4.58 lakh of annual maintenance on a 12-metre AC electric bus against ₹10.34–17.23 lakh for diesel — 56% to 73% lower. The saving comes from far fewer wearing parts, so it scales down to vans and three-wheelers.

Question 2

How often should an electric fleet vehicle be serviced?

Accepted Answer

Run three clocks, not one: high-voltage inspection, brakes, coolant and cabin filter on a six- or twelve-month calendar; tyre rotation on distance; battery items on condition. OEM schedules vary widely in India, so confirm per model.

Question 3

Should we build our own EV workshop or sign an OEM AMC?

Accepted Answer

Most fleets should do both. An in-house bay makes sense above roughly 100 vehicles at one or two depots, handling tyres, brakes and running repairs. High-voltage and battery work belongs with the warranty holder — the documented service history outweighs the labour saving.

Question 4

What is the most common EV fleet maintenance mistake?

Accepted Answer

Copying the diesel schedule across. Two failures follow: brakes inspected on a distance trigger that never fires, so calipers seize from underuse; and no state-of-health baseline captured early, so degradation cannot be evidenced later.
