Battery Cell Testing Is Crucial for Tomorrow’s Mobility

The future of mobility is carbon-neutral and the electric drive

train plays a crucial part in this transition, with the battery cell

as one of its core elements. As the smallest functional part of

the power unit, the battery has a decisive influence on cost,

efficiency, and long-term durability. Before a cell powers a ve-

hicle, it must undergo rigorous testing to prove its endurance.

AVL’s cell testing portfolio delivers the tools needed to validate

cells early, reliably, and at scale – forming the foundation for

safe, efficient, and sustainable e-mobility.

From Early Insights to Long-Term Validation

Cell testing provides the first and most critical data in battery

development. Analyzing charging and discharging behavior,

temperature effects, and aging mechanisms enables devel-

opers to detect weaknesses early, avoid costly failures, and

accelerate innovation. Reliable test results at cell level are the

basis for a robust module and pack, making this step indis-

pensable for OEMs and battery manufacturers. When imple-

menting battery cell testing, both customer groups typically

face four major challenges:

• Complexity in setting up and planning laboratories

• Need for a scalable and flexible test infrastructure

• Requirement for high accuracy and reproducibility

• Integration of digital tools for laboratory management

AVL’s Comprehensive Portfolio for Battery Cell Validation and

Characterization

To meet these requirements, AVL addresses these challenges

with a comprehensive ecosystem tailored for battery cell vali-

dation – from routine cycling to high-end characterization.

At the heart of this portfolio is the AVL CELL TESTER™, a

versatile line of cyclers designed to meet diverse testing needs.

Whether for long-term aging tests or fast, high-accuracy

validation, the CELL TESTER delivers best-in-class efficiency

through bi-directional operation, high-speed control via a 1 kHz

interface, and integrated electrochemical impedance spectros-

copy (EIS) for deeper insights into cell behavior.

Complementing this is AVL’s latest turnkey solution: the AVL

Battery Cell TS™. Engineered for rapid deployment, this com-

pact system integrates cyclers, climate chamber, and safety

components on a single transportable frame. With minimal set-

up time, it is ready to test almost immediately upon arrival. The

system supports up to 12 channels, accommodates various

cell formats, and features a CO2-cooled climate chamber for

superior energy efficiency and reduced total cost of ownership.

Equipped with intuitive automation software and lab man-

agement tools, the Battery Cell TS enables fully automated,

multi-channel testing with flexible configurations – ensuring

reliable, reproducible results while future-proofing your test lab.

AVL’s battery cell testing solutions empower engineers to reveal

the true potential of their cells – safely, efficiently, and with

unmatched precision.
