The new generation of AVL CELL TESTER™

HIGHEST QUALITY AND ACCURACY OF TESTING RESULTS

The AVL CELL TESTER™ 600A uses a unique current measurement

technique providing the best accuracy (0.01 % of actual value) among high

current cell testers while using only one current measurement range. This

provides the following benefits:

• Reduced test programming complexity by avoiding range switching

• Accuracy is proportional to the output, enabling testing capacity with

always the same proportional error

• Such high accuracy provides more reliable results and reduces test time

by enabling accurate coulombic efficiency analysis

Another feature is real-world replication thanks to high dynamic control.

With the fastest rise time on the market (0.5 ms) together with 1 ms control

and acquisition frequency, this cell tester can apply

­realistic current or power profiles and adapt test-

ing cycles based on real time models.

The CELL TESTER 600A is fully integrated and

compatible with the AVL automation software

AVL PUMA  2™ Battery and AVL LYNX 2™.

It uses a real-time EtherCAT interface with a

setting and measurement update rate of 1 kHz.

The battery cell is the most important component in the electric power­

train, both in terms of cost and performance. To ensure affordable and du-

rable battery packs, it is vital to master the electrochemical ­processes within

the cell. It is therefore crucial to conduct precise, reliable and ­accelerated

cell testing while minimizing the operation of your testbed.

To improve and accelerate electric vehicle development, AVL has developed

a series of battery cell testers. These are bi-directional, multi-channel DC

power supplies that test, diagnose, characterize and validate battery cells.

They can achieve an output current that ranges from ±2 A to ± 2,400 A

thanks to their multiple variants and the parallelization of their channels.
