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.

REQUEST SPECIFICATION

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.

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.

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.
CMBXX COMPATIBILITY
Full compatibility with ME's cell monitoring board family. 6–64+ cells per CMB, scalable to any pack size.
