Munich Electrification integrates Qulectra smart sensor portfolio for advanced EV battery monitoring

Munich Electrification consolidates its Qulectra smart sensor lineup into its core product portfolio following the closure of its joint venture with Wieland-Werke AG. This strategic shift strengthens its position in high-precision battery monitoring solutions, particularly for advanced electric mobility applications. The integration brings three key offerings—Q-SMART LIGHT, Q-SMART, and Q-SMART NEXT—under a unified development and deployment framework aimed at improving safety, accuracy, and system intelligence.

Q-SMART LIGHT focuses on precision and efficiency

Engineered for reliable performance, the Q-SMART LIGHT sensor achieves ASIL-B certification while maintaining a measurement accuracy below 0.5 percent across a current range of ±2000 A. Integrated temperature compensation ensures stable readings under varying operating conditions, while CAN bus communication enables seamless interaction with vehicle systems for State of Charge calculations. Such capabilities make it suitable for scalable EV platforms where efficiency and cost optimization are equally critical.

Q-SMART delivers enhanced safety and system integration

Advancing beyond standard measurement capabilities, the Q-SMART variant achieves ASIL-D certification, aligning with the highest automotive safety requirements. Maintaining similar accuracy and current range as its counterpart, it strengthens integration with battery management systems by delivering precise real-time data. This allows improved accuracy in SOC estimation and enhances overall battery performance reliability. Its deployment supports growing demand for intelligent Battery Management Systems across next-generation electric vehicles.

Q-SMART NEXT targets high-voltage EV architectures

Designed specifically for high-voltage environments, Q-SMART NEXT introduces advanced functionalities including integrated high-voltage measurement, pyro ignition control, and isolation monitoring. With reinforced insulation supporting system voltages up to 1500 V and an expanded current range of ±4000 A, the sensor is built for high-performance EV platforms. Its ASIL-D certification further ensures compliance with stringent safety standards required in modern Electric Vehicles and heavy-duty electrification systems.

Strategic impact on EV ecosystem

This integration reflects Munich Electrification’s commitment to strengthening its technology stack in Electric Mobility. By internalizing the Qulectra product line, the company gains full control over innovation cycles, enabling faster deployment of advanced sensing technologies. The move also aligns with industry trends toward higher voltage architectures and smarter energy management systems, reinforcing the role of precise current sensing in improving efficiency, safety, and performance across EV platforms in Germany and global markets.
