The CMU-117 Active is a next-generation cell management unit designed for real-time, bidirectional active balancing across 17 cells.
Using up to 4 A per cell through integrated DC/DC converters, it redistributes charge between cells rather than dissipating it as heat ? improving efficiency, extending range, and increasing battery lifespan.
With a measurement accuracy of ±2 mV, 3 kV galvanic isolation, and high-speed CAN-FD or TPL communication, it guarantees reliable data exchange and safe operation.
Its embedded microcontroller oversees acquisition, balancing, and diagnostics, while the 512 kB memory logs calibration data and fault events for traceability.
Certified to ISO 26262 ASIL-B and compliant with UNECE R10 / R136 standards, the CMU-117 Active meets automotive-grade requirements for vibration, shock, and EMC.
Engineered from motorsport DNA, the CMU-117 Active delivers maximum energy efficiency, reduced heat losses, and fast, reliable performance in both automotive and industrial systems.
