Charging management for electric truck depots
Exactly the charge each route needs. No more, no less.
ΔSoC = charge at departure − charge the route needs
Analyze - Secure - Optimize - Charge!
Results
Never short · ΔSoC ≥ 0
3.2%
energy prediction error on a day the model never saw — passenger-EV test
The same route can need 17% more energy on a hot day. Each truck is charged for tomorrow's route and weather, not yesterday's.
Never overpaid · ΔSoC → 0
$2.1k–4.5k
saved per truck per year by planned charging
Charging moves to the cheapest hours and stays below your grid limit. Planning 48 hours ahead adds $620–930 per truck per year.
Right-sized depot
$44k–60k
a year lost per depot by cutting a 4 MW connection to 3 MW
Connection, chargers and battery sized from your own trucks' energy — before you sign with the utility.
Lower costs and depot sizing: ΔSoC 2026 electricity study — a depot of 100 Class 8 electric trucks (500 kWh packs, 4 MW grid connection) on European day-ahead power prices (Spain, France, Germany, Denmark), Feb 1 – Aug 20, 2026; converted at $1.15 per euro. US depots are planned against your utility's time-of-use rates and demand charges. Prediction: daXos test runs on a passenger EV (VW ID.4), July and September 2026.
Works on any truck. Any brand. Any age. No access to the truck's own systems needed.
Approach
Analyze
Before the switch
Starting from the data you already have — a small daXos device fills any gap — we show which routes can go electric and the depot you need.
Secure
ΔSoC ≥ 0
Each departure gets a target: the charge its route, load and weather need, plus an agreed safety margin. A truck short must never happen.
Optimize
ΔSoC → 0
Every target is planned against tomorrow's electricity prices and your grid limit — no overcharging, no costly peaks.
Charge
Every night
Chargers and depot battery deliver each target in the cheapest hours. Every month: ΔSoC per departure and what you saved.
The rule we never break
Constraint ΔSoC ≥ 0 no truck ever leaves short.
Objective ΔSoC → 0 no overcharging, lowest cost.
The target always includes the agreed safety margin — zero never means zero reserve.
Your data stays yours.
About
ΔSoC is led by Nils Dullum, who has spent his career building the charging networks electric vehicles depend on — in Denmark, across Europe and in the United States.
Partnership
ΔSoC works with daXos Energy. daXos measures every truck on the road and predicts its energy 48–72 hours ahead. ΔSoC turns that into the depot's charging plan and runs the chargers and battery. The prediction figures on this page come from daXos Energy's test runs.
