Redundant Current and Voltage Sensing Module Designed for High-Power Battery Systems
As the electric vehicle market evolves, redundant measurement and galvanic isolation emerge as critical design standards for modern battery management.
The shift to electric mobility demands robust safety architectures in battery monitoring systems.
Operating safety, maximized capacity, and battery longevity stand at the forefront of electric vehicle engineering. Inside every high-performance electric drivetrain, the Battery Management System (BMS) acts as the central sentinel. It continuously monitors physical variables to prevent the pack from operating outside its safe operating parameters.
To meet these rigorous automotive demands, CTS offers advanced integrated sensing modules that enable real-time tracking of State-of-Charge (SoC) and State-of-Health (SoH). By reporting physical parameters directly to the vehicle's control systems, these solutions directly contribute to optimizing cell charging profiles and extending total battery lifetime.

Redundant Engineering: The CTS Hall-Shunt Approach
For applications in high-power environments, reliance on a single sensor methodology introduces single-point failure risks. Standard CTS modules utilize a dual sensing architecture to achieve robust system redundancy:
- Cu-Mn Shunt-Based Sensing: Offers high thermal stability and precision current monitoring utilizing high-resolution 18-bit measurement.
- Contactless Hall Sensor: Delivers a fully redundant, galvanically isolated 12-bit measurement.
- Direct Busbar Mounting: The compact housing is mounted directly onto a conductive copper busbar, simplifying mechanical integration.
