Detecting gases inside battery packs to prevent fires, diagnose degradation, and improve battery performance.
VOCAI brings a new chemical intelligence layer to batteries by detecting and analyzing ultra-low concentrations of gases generated inside battery packs. Its patented EFN sensing technology identifies abnormal chemical processes hours to days before cell venting, enabling preventive action against battery fires. Unlike conventional monitoring based primarily on voltage, current and temperature, VOCAI provides direct insight into chemical activity inside the battery. Beyond safety, its technology identifies battery degradation mechanisms and combines chemical, electrical and thermal data to enable deeper diagnostics, improved performance and longer battery life across energy storage, data centers, EVs, drones and robotics.
