Cargo 3-Wheeler Fleet Depot Load Calculator
Will the depot transformer carry your cargo 3-wheeler fleet chargers? Concurrent-charger limit and upgrade math.
Before signing charger purchase orders, check the transformer. Electric 3-wheelers already beat diesel on TCO in every Indian metro — at ~90 Wh/km and ₹6–8/kWh overnight power, energy cost per km is under ₹0.75. This tool computes how many chargers can run simultaneously inside a safe 80% loading limit, how many rotating groups serve the whole fleet, and what kVA an unmanaged all-on depot would actually need.
Load management beats transformer upgrades: sequencing chargers into 2 rotating groups serves the whole fleet overnight without touching the transformer — see the ToU scheduler to confirm the window still fits.
Planning estimate only — interconnection, protection settings and compliance must be reviewed and signed off by a licensed electrical engineer and your utility before energisation.

How to use Cargo 3-Wheeler Fleet Depot Load Calculator
- 1Enter the transformer rating and your charger fleet.
- 2Add other depot loads and the loading limit you'll respect.
- 3Read max concurrent chargers, the group count for full-fleet service, and the upgrade size an unmanaged depot would need.
Why use Cargo 3-Wheeler Fleet Depot Load Calculator?
- ✓Transformer-first thinking: the constraint nobody checks until the quote arrives
- ✓Safe-loading limit honored (thermal life, not nameplate bravado)
- ✓Rotating-group count to serve the whole fleet without an upgrade
- ✓Upgrade size computed for the all-on case, if you really want it
Frequently asked questions
Can my existing transformer support EV chargers?+
Count the headroom: usable capacity (rating × ~80%) minus existing load, divided by charger kW. A 250 kVA transformer with 60 kW of site load supports ~12×11 kW chargers concurrently — and far more vehicles via rotation. The calculator does this with your numbers.
Is load management really a substitute for a transformer upgrade?+
Usually, yes — overnight fleets need energy delivered by morning, not all at once. Sequencing 30 chargers in three groups of 10 serves everyone in an 8-hour window on one-third the capacity. Upgrades become necessary only when the window math (see the ToU scheduler) stops closing.
Why limit transformer loading to 80%?+
Thermal life: continuous loading above ~80% accelerates insulation aging steeply (the transformer hot-spot tools on this site show the physics). EV charging is a long-duration load — exactly the profile that cooks transformers run at nameplate.
What does a transformer upgrade cost versus management?+
A distribution transformer upgrade with civil and approvals typically runs ₹8–25 lakh and months of process; charger load-management features often cost nothing but configuration. Run this tool's group count first — most depots discover the upgrade was optional.
