Inside Spirii: V2G, EV Fleet Optimization, Grid Stability & Smart Charging

The emobility revolution isn't just about faster charging or bigger batteries. It's about intelligent systems that optimize costs, enhance grid stability, and prepare for a future where your electric vehicle becomes a power plant.

At EVS 38, Sweden, I sat down with Torben Fog, CIO and Co-Founder of Spirii, to discuss how his company is solving the biggest challenges facing charge point operators (CPOs), fleet managers, and the broader emobility ecosystem.

Who is Spirii?

Founded in 2019, Spirii is a charging management platform company operating across 22 countries.

In 2024, Spirii was acquired by Edenred, the French multinational operating in 46 countries, significantly expanding their global reach.

Spirii's platform demonstrates impressive scale with over 630,000 charge points accessible through their roaming network. Their approach spans the entire charging ecosystem:

• AC charging: Workplace, public, depot, and home charging solutions

• DC charging: From 30kW to over 400kW installations

• Megawatt charging: Already available for heavy vehicle applications

• Turnkey installations: Complete hardware and platform integration

"We are not religious in any way because it's the customers who decide which brand they want," Torben notes about their hardware agnostic approach.

The Hidden Infrastructure Crisis

While attention focuses on charging speeds and battery ranges, a critical bottleneck is strangling emobility growth across Europe: grid capacity and operational costs.

"In the Netherlands, you can have to wait years before you get the power you need," Torben reveals, highlighting a crisis extending far beyond the Netherlands to markets across Europe.

For fleet operators eager to electrify their vehicles, higher OPEX and multi-year grid connection delays represent an continuous challenge.

The Power Delta Breakthrough: 90% Cost Reduction

Spirii's most significant innovation might be the least visible to end users. Their Power Delta algorithm, developed in collaboration with Zaptec - AC wallbox manufacturer, fundamentally changes how charging stations communicate with management platforms, delivering what Torben describes as "more than 90%" reduction in data volume.

Traditional charging infrastructure sends constant updates, every second or every few seconds, regardless of whether anything meaningful is happening. A car charging at a stable 22kW for three hours generates thousands of identical data packets.

Power Delta implements deviation based reporting. When charging power is stable, the system sends updates only at specific time intervals. When power consumption changes, during charging ramp-up, interruptions, or completion, data flows freely.

"When you are increasing or decreasing your power curve, we have a lot of data coming together. But when it's stable and a lot of the charging is stable for a very long time, we only get with specific time intervals, a package of meter value update," Torben explains.

The impact creates what Torben calls a "win for everybody". CPOs save on operational expenses through lower SIM card costs, Spirii reduces processing requirements, and telecom providers handle more efficient data flows.

The Coming V2G Revolution: 2026-2027 Timeline

Perhaps the most intriguing discussion centered on Vehicle-to-Grid (V2G) technology, where electric vehicles can feed power back into the electrical grid. While current systems focus on V1G (one-directional grid services), V2G represents bi-directional power flow with transformative potential.

"I've been preaching about V2G for 5, 6, 7, 8 years myself," Torben admits. "And we are actually more waiting for the vehicles than anything else."

His prediction for commercial V2G deployment is specific: 2026-2027.

The delay isn't primarily technical. V2G works today. Nissan vehicles with CHAdeMO connectors have demonstrated the capability for years, and real V2G trials are underway in Utrecht, Netherlands, using the new Renault 5.

The challenges are regulatory and economic. "There's a little bit of an issue on the value chain on V2G, who needs to be involved in what?" Torben explains. "If you consider a cake, then a lot of stakeholders that want to have a bite of the cake and want to have the customer ownership."

But Torben sees V2G as crucial for grid resilience: "I see V2G as a key element for the future, really for the buffer of power when things are going maybe not so well. Blackout and, recently we had one."

Smart Charging and Dynamic Pricing

Spirii's platform intelligence extends to charging strategy through scheduled charging algorithms that implement "charge cheapest" functionality, timing sessions to coincide with lowest electricity spot prices.

"When you connect your bus, when you come back to the depot and you connect your bus to a charger, doesn't have to charge right away. Why not wait until the electricity is sufficiently cheap?" Torben asks.

The system knows vehicle departure times and required charge levels, optimizing within available time windows for substantial overnight cost savings.

Spirii already implements dynamic pricing that updates hourly, incorporating spot electricity pricing alongside CPO markups. The platform's grid integration capabilities extend to frequency regulation, helping maintain the 50Hz frequency standard by adjusting charging power in few second intervals.

"We can help by increasing or lowering the consumption. Maybe iterations of five seconds lowering maybe the consumption with one, two, 3%, something like that," Torben describes.

The Third Wave of E-Mobility

Torben frames current industry evolution in three waves:

1. Hardware wave: Selecting the right charging equipment

2. Digitalization wave: Leveraging software capabilities of standardized chargers

3. Integration wave: Unlocking opportunities through intelligent grid integration

We're now entering the third wave, where charging infrastructure becomes active grid participants rather than passive consumers. This evolution is particularly crucial for heavy vehicle fleets, where high equipment costs demand optimized total cost of ownership.

Battery Storage and Future Challenges

Beyond charging, Spirii delivers turnkey battery energy storage projects for grid connection augmentation, load balancing, and grid services revenue.

"With the power you can absorb or keep in the battery, then you can charge your growing fleet," Torben explains. "And we can also utilize the battery to play a role in the grid integration, balancing the grid revenue on that, giving that money back to the infrastructure owner."

The conversation revealed several critical challenges facing emobility expansion: multi-year grid connection delays, limited heavy vehicle infrastructure, need for truck specific charging reservations, and European V2G standards development.

Despite these challenges, Spirii's mission remains ambitious: "Let's see if we can save the planet together."
