Purpose-built 1500V BMS controller for utility-scale energy storage. Ethernet connectivity, extreme parallel string support, and always-on operation for grid-grade battery management.
BATTERY MANAGMENT SYSTEMS
DESIGN PHILOSOPHY
DESIGNED FOR THE GRID
The SBS Stationary is not a repurposed automotive BMS. Designed from the ground up for 1500V BESS with extreme parallel string support, always-on duty cycles, and grid-grade communication.
HV-based voltage measurement for multi-string isolation and Ethernet connectivity for modern energy management systems.
SBS STATIONARY INTEGRATION ADVANTAGES
1500 V NATIVE DESIGN
6000 V withstand, HV-based voltage measurement
EXTREME PARALLEL SUPPORT
>100 MΩ leakage isolation, up to 100 strings
GRID-GRADE COMMUNICATION
Dual-pair 100BASE-TX Ethernet + 3x CAN FD
ALWAYS-ON OPERATION
Low-power standby, optimized for grid duty cycles
KEY FEATURES
PURPOSE-BUILT FOR BESS
The SBS Stationary delivers grid-grade battery management with 1500 V native design, Ethernet connectivity, and always-on optimization for utility-scale energy storage.
1500 V PURPOSE-BUILT
1500 V rating with 6000 V withstand. HV-based voltage measurement (not GND-based). >100 MΩ leakage isolation supports up to 100 parallel strings.
ETHERNET-CONNECTED
Dual-pair 100BASE-TX Ethernet for EMS integration. 3x CAN FD at 5 Mbit/s. Future single-pair 100BASE-T1 support planned.
ALWAYS-ON OPTIMIZATION
Low-power standby for idle grid periods. Optimized for always-on duty cycles in stationary energy storage deployments.
SOFTWARE & PLATFORM
BARCELONA PLATFORM
The SBS Stationary is the grid-optimized member of ME's 3rd-generation Barcelona BMS platform, sharing a common architecture and software stack with SBS Core, SBS High, and BMDU. All SBS controllers support multistring configurations.
All four Barcelona variants run the identical SBS Software Platform. One software image supports every variant, switchable at runtime via the Configuration Framework. This means SBS Core benefits from the same validated, ASIL D ready codebase with 14-day release cadence.
Compatible with CMBXX cell monitoring board family, supporting arrays of over 500 cells per controller over 1500V-isolated isoSPI.
BARCELONA PLATFORM FAMILY
SBS CORE
Compact controller, side connectors, external shunt
ONE BINARY, ALL VARIANTS
Same software image runs on SBS Core, SBS High, BMDU, and SBS Stationary. Configuration Framework switches behavior at runtime.
14-DAY RELEASES
Continuous integration with bi-weekly validated releases. Faster iteration, faster time to production.
INDUSTRIAL CERTIFICATION PATH
ISO 26262 + IEC 61508 functional safety. EU Cyber Resilience Act (CRA) compliance planned for 2027.
SBS HIGH
Full-featured controller, integrated shunt, 7 contactor drivers
BMDU
Integrated controller + power distribution with circuit breaker
SBS STATIONARY
1500V BESS-optimized with Ethernet
SHARED SOFTWARE: All four variants run the same C++ software stack. One codebase, one safety case, one release cadence. All variants support multistring configurations.
