Churchill Group’s cars and vans are taken home by the people who drive them. Dynamon used ZERO and the fleet’s historical telematics to test which diesel vehicles can move to electric, which battery and charger fit that work, and what the change means for cost and CO₂.

Key outcomes
- Historical telematics. Duty cycles rebuilt from recorded journeys, including where each vehicle parked overnight.
- Battery and charger together. Different vehicles and battery sizes simulated with home charging, to specify the appropriate pair.
- Replacements on the existing cycle. Diesel vehicles assessed for electric when they are due to be replaced, with a full cost and CO₂ view.
Telematics and overnight parking
Dynamon collected historical telematics for the cars and vans and rebuilt the duty cycles in ZERO. The record covers the journeys the fleet already runs, and the places those journeys start and finish.
It also identified where each vehicle parked overnight. These are home stops, spread across the operation, not a return to one depot. That is the constraint on charging: a charger only helps for the hours the vehicle is already parked there.
Vehicles, batteries and charging
The diesel fleet was grouped by vehicle type, covering cars and vans of different sizes. Candidate electric vehicles were identified for each group, and ZERO simulated them across a range of battery sizes together with the home-charger options that could serve an overnight stop.
The test was which combination could cover the recorded duty cycles. Where more than one option completed the work, the appropriate vehicle and charger was the one matched to that duty, rather than a larger battery or a faster charger by default. Journeys that still fell short were identified as places a public top-up may be needed.
Replacement, cost and carbon
Feasibility was assessed vehicle by vehicle, against the point each diesel car or van is due to be replaced. The rollout follows that replacement cycle, so electric vehicles come in as the current fleet comes out.
The same operating record fed a full total cost of ownership analysis and a CO₂ analysis of the transition. Cost and carbon sit alongside the operational result: which vehicles can move, on which battery and charger, and when.
Churchill Group can replace diesel cars and vans with electric ones as they come due, with the vehicle, battery and home charger for each matched to its recorded duty cycle.
