Knick transducers optimize charge/discharge loops in batteries & microgrids

Energy storage operators face critical challenges in managing charge and discharge events safely and efficiently. Delays or inaccuracies in monitoring voltage and current can destabilize control loops, reduce system efficiency, and risk damage to costly batteries or power electronics. In dynamic applications like large battery arrays, microgrids, or renewable integration, even millisecond delays can cause significant performance issues. Knick’s high-speed, high-accuracy transducers address these pain points by providing precise, reliable measurements in near real time, ensuring control loops respond correctly while protecting both the energy storage system and connected infrastructure.

Description and requirements

Energy storage systems, from large-scale battery installations to microgrids, demand precise control of charge and discharge cycles. This requires real-time monitoring of voltage and current at high accuracy to maintain stability, prevent overcharging or deep discharge, and protect connected equipment.

Challenges include fast transients, high voltages, and fluctuating currents that can destabilize feedback loops if measurements are not delivered quickly. Additionally, isolation is critical to ensure safety for both personnel and equipment, especially in systems operating at several kilovolts. Environmental conditions such as temperature swings and electrical noise add further stress to monitoring devices.

Customers require transducers capable of combining high-speed response, robust isolation, and accurate measurement under dynamic, high-voltage conditions. Fast, precise data ensures reliable feedback for control systems, enabling operators to optimize energy flows, maintain grid stability, and extend the lifespan of storage assets.
