Cell‑level pressure, temperature and leak data that make your battery more predictable, efficient and reliable
Batteries rely on precise cell‑level data. FLEXOO’s on-cell, customizable sensors deliver real measurements — pressure, temperature and leakage — providing information needed to improve efficiency, lifetime and safety.
Cell‑level pressure & temperature sensing
Traditional battery monitoring relies heavily on voltage — but the voltage plateau of e.g. LFP cells makes 20–80% SoC nearly indistinguishable.
Pressure reveals what voltage cannot
During charge/discharge cycles, pressure follows a clear, repeatable pattern
This pattern remains stable over hundreds of cycles
Even small deviations signal aging, enabling real‑time SoH assessment
Early pressure rise reveals internal gas buildup — a pre‑indicator of TR
Leakage detection
Liquid cooling loops and electrolyte pathways are critical in high‑power batteries. Small leaks — whether from coolant lines, seals, interfaces or electrolyte‑bearing components — can quickly escalate into performance loss, safety risks or unplanned downtime.
Early leak detection
Spatially resolved sensor pixels for precise localization
Immediate resistance shift upon contact with coolant or electrolyte
Wireless data transmission (Bluetooth Low Energy)
Easy integration into new or existing system layouts
Reliable monitoring in circular, curved or constrained areas
A fully customizable sensor platform
All FLEXOO sensors are:
Free‑form, layout‑customizable and ultra‑thin
Compatible with prismatic, pouch and cylindrical cells
Configurable in density, size and sensing parameters
Available with direct BMS connection or wireless readout
From first prototypes to millions of units, every sensor is built on the same FLEXOO technology stack — ensuring performance, consistency and scalability.
This unified platform means your validation effort is required only once, regardless of production volume or sensor configuration.
