From battery safety to powertrain Validation – solving today’s testing challenges with scalable, high-accuracy DAQ solutions
EV testing is evolving—are your measurement systems keeping up?
The shift to electric mobility is pushing the boundaries of battery performance, powertrain efficiency, and end-of-line validation. Engineers and manufacturers are under increasing pressure to improve safety, enhance energy efficiency, and reduce production costs, all while dealing with higher voltages, complex energy storage systems, and increasingly stringent testing requirements.
These challenges demand a new generation of test and measurement solutions—ones that go beyond standard DAQ systems to deliver real-time insights, seamless integration, and industry-leading accuracy across a range of test environments.
Battery abuse testing needs more than just data—it needs visual proof
Battery failures can happen in milliseconds during penetration or short-circuit testing. Whether it’s a thermal runaway event or mechanical deformation, identifying the exact location requires more than just numerical data—it requires real-time, synchronized measurements with high-speed data acquisition.
HV data acquisition solutions
Our high-speed HV DAQ sy stems integrate seamlessly with video recording, ensuring that every frame is time-synchronized with electrical, thermal, and mechanical measurements on potentials up to 1500 VDC. With best-in-class noise performance and sampling rates of up to 4 MHz, engineers can capture critical events with absolute precision. The system operates remotely and fully synchronized, ensuring that even complex multi-channel test setups remain accurate and reliable under extreme testing conditions. Powerful data archiving and intelligent compression allow for long-duration testing while maintaining high-resolution data integrity.
Powertrain efficiency is only as good as the data behind it
As technology advances, EV powertrains operate at higher voltages and faster switching frequencies. Traditional power analyzers struggle to deliver accurate measurements with sufficient signal-to-noise ratio and low distortion across inverters, motors, and batteries, leading to missed efficiency optimizations.

Its intuitive software and compatibility across multiple operating systems make it a versatile solution for R&D and large-scale validation.
EIS at every level – cell, module, and pack
Battery technology isn’t just evolving—it’s diversifying. From solid-state cells to high-capacity packs, each new design brings unique challenges in voltage monitoring, impedance analysis, and thermal behavior. Many DAQ systems struggle to scale, forcing engineers to use multiple platforms for different testing stages, creating integration headaches and data inconsistencies.

The system’s open interfaces and support for multiple communication protocols ensure easy integration with third-party hardware and software.
Current measurement – detecting the hidden battery drain
EV batteries don’t just lose power on the road—they lose energy when parked. Modern electric vehicles rely on hundreds of ECUs, sensors, and electronic subsystems that continue drawing power in standby mode. Over time, these low-level power drains reduce battery longevity, shorten vehicle range, and increase warranty concerns for automakers. Many traditional measurement systems lack the resolution and real-time capabilities needed to detect power consumption in the microampere range, making it difficult for engineers to identify and eliminate unnecessary losses.
