Fleet Charging as a Service (CaaS)

Fleet managers moving to electric have a fundamental decision to make about how they structure their charging infrastructure. CaaS is one model on the table. For a general overview of what CaaS is, see our CaaS glossary entry. This article focuses on the fleet-specific considerations: how it works in practice, where it falls short, and what the alternative looks like.

What is fleet charging?

Fleet charging is the act of keeping electric fleet vehicles road-ready with enough battery power to perform their duties. Unlike petrol-powered equivalents, that normally requires forethought, strategy, and infrastructural investment.

The key challenge is time: electric vehicles take longer to charge than an ICE vehicle takes to refuel, and that means fleet managers need a strategy for ensuring vehicles have the charge they need without keeping drivers off the road. The most practical answer for most fleets is overnight or shift charging at a depot or workplace, which brings the fuelling process entirely in-house.

How does CaaS work for fleets?

Under a CaaS model, a provider installs and manages charge stations at your depot or site, handles repairs and maintenance, and takes care of billing for energy — all for a regular monthly or annual fee. For a fleet manager, it is a largely hands-off proposition.

The important caveat: if you cancel the subscription, you typically lose access to both the service and the hardware. That is why CaaS agreements usually come with minimum contract terms of five years or more.

Pros of CaaS for fleet operators

• Reduced upfront investment: the infrastructure is owned and managed by the service provider, so fleet managers avoid large capital outlays.

• Simplified management: maintenance, repairs, and updates are the provider's responsibility, freeing up internal resource.

• Scalability: infrastructure can be scaled up or down without significant additional investment.

• Future-proofing: the provider takes responsibility for keeping hardware and software current with evolving standards.

• Predictable costs: a fixed subscription makes budgeting straightforward.

Cons of CaaS for fleet operators

• Provider dependency: fleet managers rely entirely on the provider for uninterrupted access to their charging infrastructure.

• Higher long-term cost: ongoing subscription fees can accumulate beyond the cost of owning and operating hardware outright.

• Limited control: day-to-day operation and optimisation sits with the provider, which can result in timing and quality issues.

• Customisation constraints: white-labelling, API integration, and tailored workflows may be limited compared to a turnkey model.

• Disruption risk: any service outage or technical failure on the provider's side directly impacts fleet operations.

The alternative: a turnkey model with Spirii

The alternative to CaaS is owning your hardware and using a licensed software platform to manage fleet charging yourself. Think of it like the difference between a gym membership and buying your own equipment: if you cancel the membership, you lose access; if you own the equipment, it stays yours.

At Spirii, we believe the charging network should belong to the fleet, not the provider. That means offering certified hardware options or full hardware agnosticism if you bring your own, underpinned by Spirii Connect: a cloud-based platform that consolidates every fleet charging process into one place.

Through Spirii Connect, fleet managers get:

• Dynamic Load Management: optimise electricity capacity and reduce installation and operational costs.

• Dynamic Pricing: shift charging sessions to when electricity prices and climate impact are at their lowest.

• Driver management: set up compensation schemes and automated reimbursement for home or public charging.

• Full visibility: real-time insights into charging behaviour, usage, and energy consumption across all locations.

• White-labelling and API support: wrap the platform in your branding and integrate it into your existing systems.

The key benefit over CaaS: you retain ownership and control of your charging network without losing access to 24/7 support from a team of local experts.

Which model is right for your fleet?

CaaS suits fleets that want minimum operational involvement and are comfortable with long-term provider dependency. The turnkey model suits fleets that want control, flexibility, and a lower total cost of ownership over time.
