Swapping diesel vans for electric ones looks, on the surface, like a procurement decision. In reality it reorganises how a fleet is fuelled, parked, routed and financed — all at once.
Fleet electrification is a systems problem, not a vehicle swap. The vehicles are the easy part; the hard parts interact — charging logistics at the depot, the grid capacity to charge many vehicles at once, route and duty-cycle planning around range and charge time, and a total cost of ownership that's structured completely differently from diesel. Treating these in isolation is how electrification projects overrun.
For an operator running a fleet of vans, trucks or cars, going electric can sound like a straightforward substitution: choose electric models, order them, retire the diesels. The vehicles, though, are the simplest element. The genuine challenge is everything around the vehicles — and those things interact, so they can’t be solved one at a time.
1. Charging logistics. A diesel fleet refuels in minutes at a forecourt; an electric fleet charges over hours, usually at the depot, usually overnight. That means installing enough chargers, sequencing which vehicles charge when, and guaranteeing every vehicle has the energy it needs for the next day’s work before it leaves. Charging becomes a scheduling problem the operator never had before.
2. Depot grid capacity. Charging many vehicles simultaneously can demand more power than the site’s existing electrical connection can supply. Upgrading that connection is often slow and expensive — sometimes the single biggest cost and longest lead-time in the whole project. Smart charging that spreads the load over time can reduce or defer the upgrade, but only if it’s planned in from the start.
3. Route and duty-cycle planning. Range and charge time turn vehicle assignment into a constraint-satisfaction problem. Which vehicle, with which battery, can cover which route, with what charging opportunities along the way? Duty cycles that a diesel handled without thought now need to be matched to range and recharge windows.
4. Total cost of ownership. The economics invert. EVs typically cost more upfront but far less to run and maintain, and the charging cost depends heavily on when you charge. Evaluating the switch on purchase price alone gives the wrong answer; you have to model the whole lifecycle — including the value of charging flexibly at cheap, clean times.
The vehicles are the easy part. Electrification succeeds or fails on charging, grid capacity, routing and total cost — and those four are tangled together.
Because these factors interact, optimising one in isolation can quietly worsen another. Buy the longest-range vehicles and you may overspend on batteries you didn’t need. Install the fastest chargers and you may trigger a grid upgrade that smart scheduling could have avoided. Plan routes without reference to charging windows and you strand vehicles mid-shift. The only reliable approach is to treat the depot, the chargers, the grid connection, the vehicles and the duty cycles as one system, and to plan the charging schedule as carefully as the routes.
Fleet electrification is exactly the kind of multi-variable optimisation we do: sizing chargers and grid capacity, scheduling charging against tariffs and duty cycles, and modelling true total cost of ownership. It connects directly to the day-to-day operational charging problem and to charging around how vehicles are actually used. If you’re planning a transition, we can help you avoid the expensive mistakes.
