Energy
Every gallon, every kWh.For every vehicle you run: diesel, gasoline or electric.
daXos rebuilds each vehicle's dynamics, every meter, every second.
The fuel and the kWh come from real accelerations, slowdowns, driver behaviour and route context.
From $25 a vehicle a month · everything included · any brand · any driveline
What daXos Energy does
The same Hub on the diesel, the gasoline and the electric vehicle.
The same physics behind all three.
Nothing plugged into the vehicle, no OBD port, any brand.
The gallons or the kWh of every trip, per vehicle, per route, per driver.
Rebuilt from the real driving, not read off an average.
On a diesel fleet, which routes can go electric and on which truck.
One card per driver: speed, driving style, idling.
Each line in gallons or kWh, each weighed against the minutes it costs.
Only what pays is on the card.
Each vehicle's routes replayed under the forecast weather.
Gallons for the diesel, kWh and a charge target for the electric.
The depot's load for the site.
Why fleets
A fleet pays for every gallon it burns.
An electric fleet pays for the hour it charges.
Both start with knowing what each trip takes.
01Fuel
The same miles. Fewer gallons.
The fuel a delivery fleet throws away in late braking, accelerate-and-brake cycles and idling, at no cost in time.
5.3 %of the fuel, avoidable
daXos Energy puts it on one card per driver, every Monday.
02Charging
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.
03Day-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.
Fuel: two fleets on daXos units, 60 days to November 2026. Electricity: daXos study, 2026 · 100 electric trucks · day-ahead prices in Spain, France, Germany and Denmark.

The replay
daXos does not guess what a vehicle will use.
It rebuilds the vehicle's dynamics every meter, every second.
The fuel or the electricity follows 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 gallons, or as kWh if the truck were electric.
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 fuel or the kWh daXos Energy rebuilt from the day's driving, against what each vehicle actually used.
The kWh of an electric vehicle, rebuilt a day ahead and checked against the meter.
The fuel of a diesel fleet, rebuilt from the road and checked against the fuel card.
Proven on electric vehicles of different brands, in North Carolina and in Denmark, and on diesel and gasoline fleets.

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 card or a prediction.
If a device fails in normal use, a replacement ships within 48 hours, at no cost. The failed unit comes back to us.
