For over 15 years, I’ve tracked the evolution of fleet electrification from an unproven niche to a data-backed maturing industry. The early days were defined by “what ifs” and unknowns: range anxiety, battery degradation, and cold-weather performance.
Our analysis of millions of trips across tens of thousands of vehicles shows that the “EV gamble” is a thing of the past. However, a dangerous gap remains: the myths are outlasting the data. In a world where European diesel surged up to 37% in April 2026, clinging to outdated assumptions isn’t just conservative, it’s a measurable liability on the bottom line.
Here’s what the data tells us.
Myth 1: EV batteries degrade too quickly to make the investment worthwhile
The concern that battery longevity will undermine the total cost of ownership remains a primary barrier to adoption. However, data from more than 22,700 electric vehicles shows that these concerns are largely decoupled from reality.
Our analysis shows an average annual degradation rate of 2.3%. Under these parameters, a vehicle retains over 88% of its original capacity after five years. Based on our current modelling, most batteries will remain operationally viable for 12 years or more, possibly outlasting the chassis itself.
What has changed in our latest analysis is that charging behaviour now plays a much bigger role than it used to. Vehicles relying heavily on DC fast charging above 100 kW are degrading at up to 3.0% per year; roughly double the rate of those on AC or lower-power charging.
The best strategy is to use the lowest charging power that still meets your operational requirement. Save high-power charging for high-use shifts or necessary top-ups, while using slower charging for routine dwell times can prolong the life of your battery.
Myth 2: EVs don’t work in cold (or hot) weather
Temperature does affect range, but the impact is frequently misattributed. Our analysis across 5.2 million trips shows that EV efficiency peaks at 115% of rated range at 21°C. At -15°C, that efficiency can drop to 54%. Although these statistics seem concerning, -15°C operations are an infrequent occurrence for most European fleets. More importantly, the primary driver of range loss in cold weather is not the battery’s chemistry, but the auxiliary load required to heat the cabin, and the battery pack. Likewise, as temperatures rise above 25°C, range is lost due to cooling.
Pre-conditioning the vehicle while it is still plugged to the charger, saves energy for the drive. Additionally, prioritizing contact heating (seats/steering wheel) over ambient air heating is a much more efficient way to keep the occupants warm, and will allow for range recovery on the coldest days.
Myth 3: Range limitations will strand my vehicles
Range is frequently cited as a fleet-level risk, yet the data consistently fails to support this concern for the majority of applications. Our 2024 Taking Charge analysis of roughly 750,000 light-duty commercial vehicles in Europe reveals a significant gap between perceived and actual range requirements:
- 52% of vehicles never exceeded 250 miles on any single day.
- 67% of light-duty fleet vehicles drive daily distances that are within the range capabilities of EVs.
- In the UK, 84% of fleet vehicles had a range-capable EV replacement available, one capable of handling 98% of their driving days on a single charge.
What we actually observe in early adopter fleets isn’t vehicles running out of range, it’s the opposite problem: EVs being underutilized out of an abundance of caution. Our charging behaviour analysis found that 45% of European fleet EV charge sessions start before the battery drops to 50%. The more an EV is driven, the greater the fuel savings. Fleets holding vehicles back are not getting the return they paid for.
Myth 4: The charging infrastructure isn’t there yet
This objection often stems from a conflation of the public charging network with commercial depot requirements. While public infrastructure was a bottleneck in 2018, the landscape in 2026 has fundamentally shifted.
The UK alone now has 119,080 public EV chargers across 46,107 locations, a 13% increase over the previous year, with ultra-rapid chargers (150kW+) growing at 40% year-on-year. There are 972 rapid charging hubs open to all EVs across the UK, up 28% in a single year. Across Europe, the buildout has accelerated under the EU’s Alternative Fuels Infrastructure Regulation, mandating fast charging every 60km along major highway corridors.
But for most depot-based fleets, the public network is a secondary resource. Our data shows that over 50% of fleet EVs charge at just one or two locations, typically overnight at the depot, on standard AC charging. Electrification becomes a viable opportunity for commercial fleets that operate out of depots once they establish on-site charging access.
The most common hurdle today is site power capacity. A good strategy is to use telematics to audit dwell times and calculate daily energy throughput. While data can’t create electricity out of thin air, it does prevent you from solving a 200kW problem with a 2MW upgrade. By matching power needs to actual downtime, and deploying managed charging to shift peaks, most fleets can significantly minimize the scale and cost of necessary grid upgrades. For larger sites, on-site battery storage or enrollment in a demand flexibility service can provide a faster path to additional capacity than queuing for a full grid upgrade – which in parts of the UK and Europe now stretches 18 months to several years.
Myth 5: EVs are too expensive to make financial sense right now
The economic case for electrification is often judged against historic price points. In 2026, that math is obsolete. Even before the recent surge in fuel costs, the lifetime savings per EV-suitable vehicle in Europe averaged $18,400 over a seven-year cycle. On a regional basis, the base case remains compelling:
- Germany: €20,900 saving per suitable vehicle
- UK: £7,300 average saving per vehicle across the EV-suitable fleet, with 83% being economically viable when purchase incentives are factored in
But TCO comparisons tend to benchmark against efficient diesel operation. The reality is worse. Geotab’s EMEA Urban Freight Efficiency Index found that vehicles across seven European capitals burned 1.58 million litres while completely stationary in 2025 — fuel spent without a kilometre driven. At 2025 prices that was €2.6 million in idle waste. At April 2026 diesel prices, the same behaviour costs €3.5 million. That €900,000 increase in a single year is the cost of staying tethered to fuel markets – whether through inefficiency or delayed electrification. Every vehicle that moves to electric is one fewer hostage to it.
What Now?
The transition has become an exercise in asset optimization, to deploy the technology where it works. Start with an EV Suitability Assessment to see which vehicles return to base daily and where the savings are largest. Match charging power to operational need, and once the EVs are in the fleet, prioritize their mileage. Drive them hard. That’s what makes the investment pay.
The data shows EVs are ready. The question is whether fleets move quickly enough to avoid the cost of waiting.
