Energy
Every route's kWh,Not a prediction.
daXos rebuilds each vehicle's dynamics, every meter, every second.
The kWh come from real accelerations, slowdowns, driver behaviour and route context.

Why fleets
An electric fleet does not pay for distance any more. It pays for the hour it charges.
01Charging
The same miles. A different bill.
What a truck costs when it charges on arrival, against the same truck charged on a plan.
€1,826 – 3,926per truck per year
daXos Energy gives every vehicle tomorrow's kWh and a charge target.
02Day-ahead
Earlier is cheaper.
What the same depot saves again when the plan is made two days out instead of the night before.
€534 – 802more per truck per year
daXos Energy looks 48–72 hours ahead.

The offer
Fleet management, energy management and the energy forecast, in one price per vehicle. A Hub and two temperature sensors on every vehicle, any brand. We own the devices and swap them at year 4 at no cost. You pay for the data, not the box.

The replay
daXos does not predict what a vehicle will use. It rebuilds the vehicle's dynamics every meter, every second, and derives the electricity from what really happened: the accelerations, the slowdowns, the driver, the route. Give it a real diesel day and the same trips come back as kWh.
Every pull-away, every brake, every stop, as the vehicle actually did them — not an average speed over a distance.
How hard the vehicle was driven that day, by that driver, on that route — not how a vehicle of its class might be driven.
Grade, the weather of the day, historic traffic on the route, the stops and how long they lasted.
01 · Energy replay
What the trackers recorded on the left. The same trips as a Class 7 battery truck, in that day's weather, on the right. Then the same routes on a date you choose, under its forecast.
Open the replay02 · Depot readiness
Day 1 driven, day 2 planned: the charge, the energy and the power each truck needs overnight — and what the depot draws from the grid, unmanaged against scheduled.
Open depot readiness03 · Week depot replay
Seven recorded days back to back: the grid connection the depot really needs, what a battery behind the meter saves, truck-to-truck transfers, and heavier duty — winter, hills, class 8.
Open the week replayFour trucks of a pilot fleet, every recorded day since 22 August, named A to D. The replay is shared on request.
The evidence
Every evening, the kWh daXos Energy rebuilt from the day's driving against the kWh each vehicle actually used.
Same vehicle, new route, new weather and historic traffic conditions.
Proven on electric vehicles of different brands, in North Carolina and in Denmark.
See it on your own routes: five vehicles, four weeks, $0 during the trial.
Support
Three levels, included in every subscription, at no extra cost.
Every device reports its own health. One that goes quiet, loses power or drifts is flagged to us and to you, so it is fixed before a day has a gap in it.
Charging happens overnight and at weekends. Chat with the daXos team whenever you need an answer about a vehicle, a charge or a forecast.
If a device fails in normal use, a replacement ships within 48 hours, at no cost. The failed unit comes back to us.
