Charge Management and Fleet Management Systems: Integration for Smarter Fleet Operations

Why FMS and CMS Integration Matters

The integration between Fleet Management Systems (FMS) and Charge Management Systems (CMS) has become a critical success factor for electric fleet operators.

Bia enables seamless communication between both systems, helping operators unlock the full potential of charge optimization (smart charging and dynamic load management) and on-road optimization

With this integration, fleets can:

• Exchange real-time data between vehicles, chargers, and logistics operations.
  
  
• Consolidate systems into one platform for unified EV fleet management and to get complete BI reporting.
  
  
• Ensure fleet uptime through automated coordination of schedules and charging sessions.
  
  
• React instantly to emergencies—when the FMS sends a signal for an urgent departure, the CMS dynamically reallocates power to specific chargers.
  
  

This connection bridges two complementary worlds: logistics intelligence and energy intelligence. Together, they form the foundation for efficient, scalable, and cost-effective fleet electrification.

Minimum Data Requirements

To deliver optimal smart charging, Bia’s software requires only two key data points per vehicle:

1. Fleet Schedule: Departure time of each vehicle.
   
   
2. State of Charge (SoC) at Arrival: The battery percentage when the vehicle returns to the depot.
   
   

Using this data, Bia’s EV charging management software determines both the required energy and power to ensure every vehicle is fully charged before departure — while minimizing costs and respecting electrical constraints.

How Data Exchange Works: DC vs. AC Charging

The way data is shared depends on the charger type:

• DC Chargers:
  Through the OCPP protocol, DC chargers identify vehicles automatically and transmit SoC in real time. The CMS therefore only needs departure schedules from the FMS.
  
  
• AC Chargers:
  OCPP does not identify vehicles or send SoC data. In these cases, the CMS retrieves this information directly from the FMS via an API.
  
  

In both scenarios, a simple one-way API integration (FMS → CMS) provides the minimum data needed for smart optimization of charging sessions.

Advanced Platform Integration

Beyond the minimum setup, Bia offers advanced integrations between FMS and CMS with bi-directional data exchange and deeper interoperability.

This allows:

• Continuous recalculation of optimal charging schedules based on live inputs from both systems.
  
  
• UI-level integration, displaying FMS and CMS insights within the same dashboard tab.
  
  
• Full data centralization, giving operators one single view of their fleet, chargers, and energy assets.
  
  

While advanced integration takes more time to implement, it offers powerful benefits — a unified operational view, faster decision-making, and stronger energy performance analytics.

Bia’s Experience: Real-World Integrations

Bia has successfully integrated its charge management platform with multiple leading Fleet Management Systems:

• Webfleet – Advanced integration launched in 2023. Webfleet’s dashboard now displays a dedicated tab with charging and load optimization data from Bia.
  
  
• EMT Madrid – 311 charging points across 3 depots connected with Bia’s CMS.
  
  
• EMT Valencia – 54 chargers integrated and optimized through Bia’s software.
  
  
• Alsa – Integration with 7 charging points and Alsa’s in-house FMS platform.
  
  

Bia also supports custom API integrations with in-house fleet management systems — a popular choice among operators like EMT Madrid, EMT Valencia, and Alsa — allowing automatic retrieval of vehicle schedules and real-time optimization of charging operations.

Key Benefits of CMS + FMS Integration

Integrating both systems unlocks significant advantages:

• Up to 25% lower charging costs through optimized schedules and smart energy usage.
  
  
• Reduced power peaks and grid constraint issues via dynamic load management.
  
  
• Improved fleet reliability thanks to automated coordination between routes and charging.
  
  
• Centralized business intelligence combining mobility and energy data in one place.
  
  

With Bia Smart Charging, operators transform complexity into clarity — achieving higher uptime, lower total cost of ownership (TCO), and smoother depot operations.
