IEST Battery Pressure Mapping Sensor Measurement System (BPD Series)
The IEST Battery Pressure Mapping Sensor Measurement System delivers precise, real-time interface pressure mapping and temperature monitoring for cell and module-stack compression analysis. Using high-resolution sensor arrays and multi-channel synchronous acquisition, it maps and quantifies surface pressure distribution and produces synchronized force/time and temperature profiles. The system validates pressure uniformity, tracks pressure evolution during cycling, and enabling rapid evaluation of cell flatness, lamination uniformity and module-level swelling forces. Ideal for EV battery R&D, quality control, failure analysis and process optimization.
Features:
- Capable of displaying real-time total force curves from all sensors versus time.
- Flexible pressure-map selection and customizable sensing area to match coin cell, pouch cell, prismatic cell and module layouts.
- Real-time synchronization with charge/discharge data to correlate electrochemical events with mechanical stress.
- One-click to export the data report.
- Real-time pressure calibration and optional integration with in-situ swelling fixtures for combined thickness/force studies.
Application:
- Integrated with swelling fixtures, force distribution analysis during cell cycling
- Pressure uniformity validation in hot press lamination processes
- Quickly and quantitatively evaluate the surface flatness of the cell.
- Module-level cell swelling force profiling
1. Introduction
Designing batteries that deliver optimal performance, extended cycle life and uncompromised safety requires a clear view of how pressure and temperature behave throughout development and manufacturing.
The IEST Battery Design Pressure Measurement System(BPD Series) integrates pressure and temperature sensors to supply engineers with high-accuracy, real-time interface maps and analytics — enabling faster process optimization and more reliable battery designs.
2. Why measure pressure & temperature in batteries?
During charging and discharging, electrodes, separators and cell housings undergo dimensional and thermal changes. If left unchecked, these effects can trigger problems such as:
- Mechanical delamination and separator damage
- Gas generation and swelling
- Surface deformation and poor interfacial contact
- Accelerated capacity fade and reliability loss
- Elevated risk of thermal runaway
3. What real-time battery pressure mapping sensor delivers?
The IEST system provides dynamic, high-resolution visualization of surface pressure and temperature across cells, modules, and mechanical assemblies. Continuous pressure and temperature mapping produces reproducible, time-synchronized datasets.
With this visibility engineers can:
- Ensure even stack compression across cells and modules
- Minimize process variation during formation and assembly
- Pinpoint high-stress or low-contact zones for corrective action
- Monitor temporal trends and pressure drift over cycling
- Capture pressure response during thermal excursions for safer fixture and pack design
