Mobile DC Charger Case Study: 40kW XC Series for Paris Olympics Electric Fleet Support

Challenge

During the Paris 2024 Olympic Games, the French government deployed a fleet of electric vans and buses​ to transport athletes, officials, and event materials across the city. These vehicles operated on dynamic, multi-route schedules​ with no fixed depot — traditional charging infrastructure couldn’t keep pace with the fluid logistics.

The organizing committee needed:

  • Mobile charging that moves with the fleet​ — not the other way around.
  • Rapid power input connection​ — ability to tap into available three-phase sources at different venues and checkpoints.
  • Command-vehicle integration​ — charger and cables must fit inside or be towed by a support/command vehicle.
  • Mission-critical reliability​ — zero tolerance for charging failures during live events.

Max Power Solution

XC Series 40kW mobile DC single-gun charger, integrated into a command vehicle

  • 40kW DC output​ — sufficient to top up electric vans (60–100kWh batteries) during 30–60 minute dwell windows between routes.
  • Command-vehicle configuration​ — charger secured inside a government electric support van; input cables and DC gun stored in dedicated compartments for rapid deployment.
  • Flexible input options​ — compatible with 380–480V three-phase supplies available at venues, emergency services hubs, and temporary power distribution points across Paris.
  • Sub-5-minute setup​ — from vehicle arrival to charging start: unroll input cable, connect to available power source, plug DC gun into vehicle. Total elapsed time: under 5 minutes.
  • OCPP 1.6J remote monitoring​ — central operations team tracked state of charge, session duration, and fault codes across all mobile units via cloud dashboard.
  • Ruggedized for road use​ — shock-mounted internal components, vibration-tested chassis, and temperature-controlled enclosure ensured reliability during constant transit.

🔑 Operational innovation: The XC 40kW wasn't just a charger — it was a logistics enabler. By pairing the charger with a command vehicle, organizers created a "charging-as-a-service" node that could be repositioned hourly based on fleet demand. When one route finished, the support van relocated to the next checkpoint, plugging into whatever power was locally available.

Results

  • Zero missed departures​ — all electric fleet vehicles completed their assigned routes; no athlete or material transport delayed due to charging.
  • Rapid redeployment​ — support van relocated 3–5 times daily across Paris venues; average setup-to-charge time: 4.2 minutes.
  • Grid flexibility​ — tapped into 12+ different power sources across the city (venue panels, generator tie-ins, temporary distro boxes) without requiring dedicated infrastructure.
  • Scalable model​ — the same configuration was replicated for other government electric fleets during the Paralympics and subsequent Paris events.

Takeaways for Event & Emergency Fleets

  1. Charging must follow the mission​ — fixed stations are useless when vehicles are constantly moving.
  2. Sub-5-minute setup is non-negotiable​ — specify chargers with plug-and-play input and cable management designed for rapid deployment.
  3. Command-vehicle integration​ — design the charger as part of a mobile kit, not a standalone device.
  4. OCPP monitoring at scale​ — remote visibility across dispersed mobile units is essential for operational control.
