SBS HIGH
Full-featured BMS controller with integrated dual shunt, 7 contactor drivers, 8 HV measurement channels, and pyro-fuse protection for complex modular architectures.
BATTERY MANAGMENT SYSTEMS
DESIGN PHILOSOPHY
BUILT FOR COMPLEX ARCHITECTURES
When battery packs need multiple HV connections, complex switching strategies, and precise integrated current measurement, SBS High delivers. 7 contactor drivers, 8 HV channels, and an integrated 35 µΩ dual shunt give system designers the full peripheral set for demanding modular architectures.
The highest peripheral count in the Barcelona family means fewer external components, simplified wiring, and a single controller that handles current sensing, contactor management, and HV monitoring without compromise.

KEY FEATURES
FULL PERIPHAL SET
The SBS High delivers the highest peripheral count in the Barcelona family with integrated current measurement, eliminating external sensors and simplifying system design.
INTEDGRATED DUAL SHUNT
Built-in 35 µΩ dual shunt measures ±1,000 A at ±0.5% accuracy. Peak 500 A for 60 seconds. No external current sensor needed.
HIGH PERIPHAL COUNT
7 contactor drivers (6 normal + 1 PWM). 8 HV channels across ±1,000 V. 6 sensor inputs, KL15 ignition input, 12V sensor supply.
PYRO-FUSE PROTECTION
Dedicated pyro driver with backup capacitor for fast short-circuit reaction even during power loss. Detection up to 15,000 A.
SOFTWARE & PLATFORM
BARCELONA PLATFORM
SBS High is the full-featured member of ME's 3rd-generation Barcelona BMS platform, sharing a common architecture and software stack with SBS Core, BMDU, and SBS Stationary. 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 High benefits from the same validated, ASIL D ready codebase with 14-day release cadence.
The platform is compatible with ME's CMBXX cell monitoring board family, supporting 6 to 64+ cells per board. SBS High connects via isoSPI in bus topology for reliable cell monitoring communication.
