The CMU-118 enhances XAP?s modular BMS platform with a precise, 18-cell passive balancing architecture.
Each cell is monitored with ±2 mV accuracy, while galvanic isolation up to 3,000 V guarantees safe operation across logic, cell, and communication domains.
Equipped with MOSFET-controlled passive resistors (?4.7 ? / 3 W) and an advanced sequential balancing algorithm, the CMU-118 minimizes voltage deviation (<25 mV) for optimal pack stability.
Its isolated TPL communication bus ensures reliable data transfer with built-in CRC and watchdog protection, making it ideal for multi-module systems and retrofits.
With EEPROM-based traceability, complete protection suite (ESD, reverse polarity, transient surge), and long-term reliability over 13,000 hours, the CMU-118 is the perfect solution for industrial, marine, or high-voltage electric vehicles.
Industrial-grade robustness and motorsport-inspired reliability, delivering accurate measurements, safe isolation, and unmatched endurance for demanding energy systems.
