Battery Management for mobile Applications

The Mobile Battery Management System (MBMS) from Stercom is specifically designed for mobile applications, ensuring optimal utilization of battery capacity. With precise detection of individual cell deviations at the module level, our Dynamic Cell Balancing (DCB) technology immediately compensates for any imbalance across the entire string. This ensures efficient use of available capacity and significantly enhances battery safety and lifespan.

The MBMS manages optimal balancing strategies, accurately determines battery health (SoH) and state of charge (SoC), and can even automatically configure and control multi-string systems. These advanced capabilities make it the perfect solution for tackling challenges in mobile energy storage.

MBMS Features

  • SoC measurement (battery) and SoH detection (cell level)
  • Extended self-test functions
  • Monitoring of battery operating status
  • Multi-stage cell voltage monitoring
  • Temperature-controlled current and voltage derating
  • Cell temperature monitoring
  • Safety shutdown
  • Residual current monitoring (earth fault)

Public Transport

In electric bus fleets, the MBMS optimizes battery management, maximizing range and lifespan. By implementing battery management systems for electric buses, cities can significantly reduce CO₂ emissions.

Construction Vehicles

In modern electric construction machinery, the MBMS ensures reliable and efficient power supply, optimizing battery usage for construction equipment. This is crucial for companies integrating eco-friendly technologies into their machines.

Municipal Vehicles

Electric municipal vehicles, such as garbage trucks or service vehicles, benefit from intelligent battery monitoring and optimized battery capacity utilization. The MBMS helps reduce operating costs and minimize environmental impact.

Marine Applications

In electric propulsion systems for ships and boats, the MBMS provides a safe and efficient power supply, maximizing operating time and minimizing downtime. It offers battery management solutions tailored to marine applications, ensuring both performance and safety.
