Elevating Cell Validation and Diagnostics with Integrated EIS

Feature

Maintaining battery safety and performance requires more

than basic electrical measurements. EIS offers deeper insights

by applying a small AC signal and analyzing the battery’s

response across a range of frequencies.

This non-invasive method reveals key internal characteristics

such as resistance, charge-transfer kinetics, and diffusion be-

havior – factors that are critical for understanding cell aging,

efficiency, and degradation mechanisms. In other words, EIS

can provide a frequency-dependent fingerprint of the electro-

chemical system, enabling a clearer understanding of what

happens inside the system throughout its lifecycle.

Designing the Battery Labs of Tomorrow

Tomorrow’s energy systems demand laboratories built for

flexibility, efficiency, and scalability. AVL delivers everything

needed for this task, from climate chambers and cyclers to

intelligent software. But what truly sets us apart is how we

rethink the lab itself.

Our in-house developed software AVL ONTEC makes planning

a battery test lab as simple as building with digital building

blocks. Every piece of equipment is available with its re-

al-world dimensions, updated directly from development. With

just a few clicks, entire facilities can be arranged, visualized,

and even explored in virtual reality – long before the first wall

is built.

This creates certainty where it matters most: Are escape

routes clear? Is there enough space for safe operation and

easy maintenance? How will the lab feel when people are actu-

ally working in it? AVL ONTEC answers these questions early,

turning potential challenges into confident decisions.

What makes the tool even more powerful is its flexibility.

Existing building data, customer models, and 3D scans can be

imported seamlessly, allowing every lab to be tailored precise-

ly to its environment. The result is a facility that is not only

efficient and safe but also future-ready.

AVL ONTEC combines cutting-edge technology with decades

of expertise to transform the complex task of lab planning into

a smooth, inspiring experience – bringing the laboratories of

tomorrow to life today.

Supporting Future Mobility Goals

AVL’s testing solutions directly address key customer challeng-

es in accuracy, scalability, and integration. By enabling faster

and more reliable validation, they shorten development cycles

and increase confidence in performance. OEMs and battery

manufacturers alike benefit from scalable and flexible sys-

tems that grow with their needs, while intelligent integration

of hardware and digital tools ensures safety and efficiency.

With this approach, AVL empowers customers to develop and

validate safe, durable, and sustainable battery cells – securing

the foundations for tomorrow’s mobility.
