Route & energy simulation for electric truck fleets

Will this truck make this route, loaded, in winter — and where does it charge? Spec-sheet ranges assume mild weather, flat roads and optimistic consumption; fleet planners need an honest answer.

That takes a physically explainable energy model — not a black box — that planners can interrogate corridor by corridor.

I built the route simulation: consumption scaled by gross weight, ambient temperature (cold hurts more than heat), speed-dependent aerodynamics, and per-segment elevation with regeneration credit on descents.

Charging stops follow realistic charge curves with cold-battery derating; a stop of 45 minutes counts as the mandatory EU driver break.

Routes come from an HGV routing engine; the map colors the route by state of charge — green fading to red exactly where the battery does.

Planners see in seconds whether a truck-route-temperature combination works — instead of trusting a brochure range.

The failure cases matter most: a regional truck at −10 °C visibly does not arrive. That is the conversation to have before purchase.

A simplified version of this model runs live on this site.
