Chatelineau Success Story

Belgium’s Fastest-Growing Charging Site: Sparki’s 2F Success Story in Chatelineau

Belgium’s EV landscape is growing rapidly, but one site stands above the rest for a reason that’s more technical than it first appears: Sparki’s ultra-fast charging site in Chatelineau has become the country’s fastest-growing location not because of size, but because of its Dual Front configuration.

At the heart of this success lies the WILLBERT Amber II S-HUB 2F, a dual-sided powerhouse capable of delivering peak power per plug of 600 kW, available to be dynamically distributed across eight plugs. Unlike traditional “hub” setups that cluster multiple independent chargers together, the 2F configuration consolidates intelligence, power, and user interaction into a single modular system, creating a compact yet high-performing node that outclasses even 3- or 4-charger hubs in both output and uptime.

Who is Sparki?

Sparki is a forward-thinking Belgian Charge Point Operator (CPO) that built its reputation on highest performance, accessibility, and customer experience. Their mission has always been clear: make EV charging as intuitive and reliable as refueling.

When Sparki became the first operator to deploy the WILLBERT Amber II system over 2 years ago, they weren’t just testing new hardware — they were redefining how performance, reliability, and scalability can coexist at a retail charging site. The partnership between Sparki and WILLBERT has since become a benchmark in next-generation ultra-fast charging.

Why Chatelineau’s 2F Setup Beats Hubs

Traditional “hub” or multi-plug sites typically rely on either multiple standalone chargers with two plugs each or on complex distributed systems. Standalone setups require every unit to have its own control and cooling systems as well as its own maintenance cycle. At the same time, this approach leads to compromises in peak power delivery because energy-sharing flexibility is limited. Distributed charger configurations, on the other hand, rely on fragmented architectures with separate power cabinets and auxiliary infrastructure, making them more expensive to install, harder to manage, and significantly more space-consuming.

The 2F configuration, by contrast, combines the best advantages of both approaches:

• A single power core integrated directly into two interconnected standalone chargers,
• Four user touchscreens and payment terminals in the smallest possible footprint,
• Eight charging plugs delivering up to 600 kW of peak power — all within a total footprint of less than 2 m²,
• Smart Power Allocation that dynamically distributes the 600 kW capacity among all connected vehicles by optimally reallocating power modules between plugs throughout charging sessions, according to vehicles’ needs.
• Simultaneous charging for up to eight vehicles — without the energy waste, queuing, or underutilized capacity typical of conventional hub setups,
• Expandable capacity up to 720 kW as demand increases.

This means that the Chatelineau site, even with just one 2F S-HUB system, can outperform a setup of multi standalone chargers in both utilization and revenue per square meter. It’s a model designed not for scale in the number of boxes, but for scale in power density and operational efficiency.

Performance That Speaks for Itself

Since its commissioning in May 2024, the Chatelineau 2F site has delivered:

• 428.6 MWh of energy through 16,316 successful sessions
• An average session of 27 minutes, delivering 26.4 kWh per charge
• Around 16.5 MWh of energy delivered weekly, and average 1300 sessions monthly in Q3 2025
• Consistent growth despite market slowdown — a sign of a superior design and driver trust

Uptime and Reliability Beyond Industry Standards

At 99.8% uptime, the Chatelineau 2F configuration demonstrates what standalone hub architecture can achieve. Traditional hubs depend on each charger’s independent system — meaning a single failure takes out capacity. The 2F system isolates faults internally while keeping all other plugs live, ensuring no downtime cascades and maximum business continuity.

The site consistently ranks among the highest-performing charging locations, showcasing how a high-capacity Dual-Front setup unlocks exceptional throughput and reliability.

Technology That Powers the 2F Advantage

Every part of the WILLBERT Amber II S-HUB 2F system is backed up by our HAWKe backend platform:

• PayBERT: enables direct terminal payments — no apps, no friction
• AdBERT: monetizes the screen interface through on-site advertising
• TechBERT: delivers proactive maintenance insights for 24/7 uptime
• BizBERT: provides detailed analytics

Together, these systems transform the charger into a smart retail node — one that not only charges cars but engages customers, generates secondary revenue, and provides granular control over business performance.

A New Standard for Compact Ultra-Fast Sites

Chatelineau demonstrates that “less is more” when the system architecture is intelligent enough. Instead of expanding horizontally by adding more chargers, the 2F model scales vertically, delivering higher power, denser functionality, and smarter energy distribution within a dramatically smaller footprint.

Compared to hubs built from three standalone 200 kW chargers:

• The 2F system provides up to 600 kW of dynamically allocated power, unconstrained by per-plug limits.
• It uses roughly half the footprint, with significantly reduced civil works, simplified cooling, and streamlined cabling.
• It delivers superior ROI per installed kilowatt, enabled by shared infrastructure, a unified power core, and centralized service architecture.

What’s most remarkable is utilization: with just two chargers, the Chatelineau site matches the average daily session volume of Fastned’s high-utilisation highway locations, which rely on multiple chargers to reach comparable throughput (Fastned Investors Presentation, June 2025).

The outcome is clear: higher throughput, lower cost, and greater reliability—all achieved through power density and system intelligence rather than simply adding more boxes.

Conclusion: The Future Is Dual-Front

The success of Sparki’s Chatelineau site proves a clear point: future-ready charging doesn’t mean adding more boxes; it means building smarter systems.

With the Amber II S-HUB 2F, WILLBERT and Sparki have shown that a compact, modular, and intelligently distributed setup can outperform even the most sophisticated multi-charger or distributed charging hubs, while setting new standards in uptime, user satisfaction, and return on investment.

Chatelineau is not just Belgium’s fastest-growing charging site — it’s a preview of how the next decade of ultra-fast charging will be built.
