Managing a Mixed ICE and EV Fleet: A Practical Guide

A mixed fleet runs internal-combustion (ICE) vehicles and electric vehicles side by side, which means managing petrol and diesel alongside electricity, two very different cost structures, at the same time. Here's how to keep control as your fleet electrifies.

What makes a mixed fleet harder to manage

Fuel is measured in litres and bought on fuel cards at stations; charging is measured in kWh across depot, home, and public chargers. The data lives in different systems, and the cost structures don't compare directly, which makes it hard to see the true cost of running the fleet.

Compare true cost per mile across ICE and EV

The only fair way to compare a diesel van with an electric one is cost per mile. Normalizing both fuel and charging costs to cost per mile shows which vehicles and routes are actually cheaper to run, and where electrification is paying off.

Keep fuel and charging in one view

Managing fuel cards in one place and charging in another guarantees blind spots. Consolidating fuel and EV charge data into a single view is what lets you audit both, catch anomalies, and report accurately.

Use data to guide the transition

Usage and cost-per-mile data tells you which routes and duty cycles suit EVs today and which don't, so you electrify where it saves money rather than by guesswork.

How Fleevo helps

Fleevo brings fuel and EV charge data into one fuel and EV management view, with cost per mile across ICE and EV and a live total cost of ownership picture for mixed fleets.

Frequently asked questions

Is an EV always cheaper per mile than a diesel?

Often, especially charged at depot on off-peak tariffs, but heavy public rapid charging can narrow the gap. Cost per mile is the way to know for your fleet.

Can one platform manage both fuel and charging?

Yes. A fleet spend platform can consolidate fuel card and EV charge data into a single view.

How do I decide which vehicles to electrify?

Use route and cost-per-mile data to target the duty cycles where EVs save money.
