A battery cell test system is a testbed that includes at least one temperature chamber suitable for testing lithium-ion batteries, a cell cycler in the appropriate current and voltage range, and an automation system. The size of the cell determines which of the various chambers with special safety equipment is required. In addition to the chamber, the cell cycler and the required current and voltage ranges must be aligned with the respective cell.
Along with our test system, we also offer automation software for performing all types of fully automated tests. The products mentioned above, but also special equipment such as Electrochemical Impedance Spectroscopy (EIS) can be integrated and operated within our AVL Battery Cell TSTM. We also offer software solutions for running entire laboratories with several thousand cell test channels via AVL Lab Management™ for Battery.
While the selection of individual laboratory power supplies is not a big challenge, the configuration of a testbed that fully automatically controls 15 different components from different manufacturers with 60 channels for more than 1000 hours without error is much more difficult. This is why we developed the AVL Battery Cell TSTM. Whether cell cyclers for 0.5 A to 2400 A, EIS meters for 5 A or 30 A, measurement of voltage, resistance, current or a safety PLC, we deliver a test system tailored to your needs.
Perfect Planning
AVL Lab Management™ for Battery provides the perfect support for controlling several thousand channels automatically.
Fully Automated Control
A test often consists of several subareas requiring different equipment. AVL’s automation software enables various types of devices to be integrated and controlled fully automatically.
Automated Evaluation
AVL software tools offer many options for creating libraries and performing online calculations, for example, to facilitate post-processing.
Testing All Influences
AVL works alongside many chamber manufacturers and can offer all types of climatic conditions, such as temperature and humidity, as well as salt and dust, for example.
Testing Beyond Limits
To get the maximum possible performance from batteries, AVL offers a specially developed safety chamber and equips complete safety laboratories with various testing options.
Specifications
The AVL Battery Cell TS™ can be adapted to a wide range of customer requirements. Typically, our battery cell test systems consist of the following subsystems:
Testbed Automation
Depending on the performance required, the AVL automation system supports up to 64 channels in real time. Moreover, our automation software enables various types of devices to be integrated and controlled fully automatically. → Learn more
Climate Chamber
We offer different chambers with and without humidity. The typical temperature range is between -40 and +90 °C. → Learn more
Cell Cycler
The AVL CELL TESTER™ supports a current range from 2A up to 2,400A by parallelize the power channels. → Learn more
Cell Holder
Cell Holder and Fixture systems are designed for a variety of shapes and sizes, such as coin, prismatic, pouch, cylindrical.
Safety System
We have designed the safety system according to the expected risk level based on our cell analysis database.
Measurement Systems
Based on customer requirements additional sensors for temperature, force and displacement can be integrated.
Design Based on Battery Design Verification Plan (DVP)
Our expertise ranges from standards and norms to verification processes. We draw on this to derive the necessary requirements and tailor testbeds perfectly to customer needs.
Space-Saving Design
Aware that all surface area used generates costs, at AVL we focus on space-saving design, even for subcomponents.
Single Source
We sell individual products, through complete test systems to turnkey test labs with AVL Battery Cell TS™. The testbed automation communicates seamlessly with all components and is controlled by AVL Lab Management™ for Battery.
Greatest Measurement Accuracy
To achieve the objectives of the test procedure, we have developed our products with the greatest measurement accuracy of up to 0.01% FS.
Continuous Real-Time System
Each test channel can be controlled and monitored such that an important threshold of at least 100 Hz depending on architecture is not exceeded.
Regenerative System
To keep energy costs as low as possible, every cycler at AVL is designed to be regenerative so that energy can be returned to the grid.
Global Presence
AVL is represented around the world and supports customers locally with experts on site.
As a partner with a global presence and with knowledge of battery development, simulation, and production, AVL is a reliable, competent partner in the area of test systems for batteries.”

AVL’s E-Library is a mindful solution that introduces simplicity when dealing with e-testing complexity, provides a fast track to productivity, and offers reassurance that targets will be met – putting your mind at ease and allowing you to enter the market with full confidence.
We offer complete test systems for the testing of modules/packs. Learn more about which hard- and software products are included in our test systems.
To ensure that batteries deliver optimal performance over the longest possible lifetime while meeting strict safety standards, we have developed the AVL Battery TS™ End Of Line. From modules to battery packs, this test system enables battery testing in production. The system covers Conformity of Product (CoP) and Quality Assurance testing.
Battery packs, modules and cells, fuel cells, e-motor and e-axle solutions must operate safely and reliably in any environment. This can include extreme temperatures and humidity, which cannot be reproduced on the test track or in real test scenarios on the road. This is why we developed the modular AVL Climate Chamber.
Thermal conditions and environment of Units Under Test have strong impacts on real results in driving. For this reason, the thermal simulation must be as exact as possible – which can be achieved via deployment of high performing media conditioning systems.
