Battery manufacturers and electric vehicle OEMs need to ensure the durability, safety, and optimal performance of batteries in EVs and energy storage systems. Advanced testing is essential for accurately analysing key variables such as temperature, strain and electrochemical behaviour in environments with high electromagnetic interference, high voltage, and limited space, without compromising data integrity or safety.
HBK provides advanced optical measurement solutions for battery testing combining Fiber Bragg Grating (FBG) technology with integrated, flexible data acquisition (DAQ) platforms. Our tailored solutions enable seamless hybrid measurements and comprehensive data analysis, supported by extensive application expertise.
Their small size and low mass give them an extremely short response time, enabling almost immediate heat transfer. This responsiveness is critical for accurately capturing dynamic thermal events inside a battery.
They are immune to electromagnetic (EM) and radio frequency (RF) interferences. Unlike traditional electrical sensors that can fail or need extensive protection, FBG optical sensors deliver reliable, accurate, and stable data, making them perfect for battery testing environments.
Optical sensors are passive and constructed from dielectric (electrically insulating) materials. This design makes them intrinsically safe for high-voltage applications and prevents them from interfering with other operations. They don't require an excitation signal, and their insulation means they can even be left inside a battery after testing, which saves time and resources.
Fiber Bragg Grating (FBG) technology allows for multipoint measurements through a single fiber optic cable. This multiplexing capability lets you define the number of measuring points and their position, enabling detailed strain and temperature mapping with minimal cabling and reduced interference with the battery.
HBK's QuantumX MXFS optical interrogator module is designed to integrate seamlessly with the complete QuantumX data acquisition (DAQ) platform. This allows for flexible and precise hybrid measurement chains to be set up quickly and easily using a "Plug and Measure" approach with software like catman.
This will bring together HBM, Brüel & Kjær, nCode, ReliaSoft, MicroStrain and Discom brands, helping you innovate faster for a cleaner, healthier, and more productive world.
