Saft, a subsidiary of TotalEnergies, has launched OptiLife, an advanced embedded solution designed to enhance battery performance and enable predictive maintenance across industrial and Internet of Things (IoT) applications.
OptiLife is an innovative electronic circuit integrated directly into Saft’s primary lithium batteries, delivering real-time and highly accurate insights into a battery’s State of Charge (SoC). The solution is aimed at improving operational efficiency and reliability in sectors such as smart metering, asset tracking, transportation, and large-scale IoT deployments.
Powered by a patented algorithm developed over two decades, OptiLife models key factors affecting battery performance, including self-discharge during storage and operation, temperature variations, and low background currents. This enables accuracy levels of up to 95%, offering operators a clear and continuous view of battery health throughout its lifecycle.
The system supports voltages ranging from 4V to 50.4V and operates in extreme conditions from -40°C to +85°C, making it suitable for harsh environments. Its robust design also allows encapsulation within the battery pack, ensuring durability and long-term performance.
OptiLife’s real-time monitoring of current, voltage, and temperature helps businesses transition from reactive to predictive maintenance strategies. By providing precise data on battery aging and consumption patterns, it allows operators to plan maintenance proactively, reducing downtime, minimizing service visits, and preventing premature battery replacements.
According to Olivier Girard, Battery Development Manager at Saft, the solution sets a new benchmark in battery intelligence, particularly as IoT ecosystems continue to expand and demand more reliable energy monitoring solutions.
Manufactured at Saft’s facility in Poitiers, France, OptiLife is now available for integration into industrial devices using LS and LSH battery chemistries. The launch marks a significant step forward in enabling smarter, more efficient energy management for connected devices worldwide.
