VIDEO: EV battery testing with next-level turnkey solutions from AVL
In a recent interview with Charged, Dr. Christian Meisner, Global Vice President of Battery and Cell Testing at AVL, delved into the company’s innovative battery testing solutions tailored for the evolving EV industry. AVL, with a legacy spanning over 75 years in the automotive sector, has diversified its expertise across three primary divisions: simulation, powertrain engineering, and test systems. Dr. Meisner’s focus lies within the test systems division, emphasizing AVL’s commitment to delivering turnkey solutions for comprehensive battery and cell testing.
AVL offers a suite of battery testing solutions encompassing the entire spectrum, from individual cells to complete battery packs and modules. These systems are designed to ensure optimal performance, safety, and durability of battery systems. A standout offering is the AVL Battery Cell TS, a test system that integrates various components such as temperature chambers and cell cyclers, tailored to the specific requirements of different battery cells. This system facilitates fully automated testing, enhancing efficiency and accuracy in battery development processes.
To address the intricate demands of battery cell research and development, AVL has introduced the AVL CELL TESTER. This bi-directional, multi-channel DC power supply is engineered to test, diagnose, characterize, and validate battery cells, achieving a wide range of output currents. The tester boasts exceptional accuracy to ensure reliable results and reduce test programming complexity. Such precision is crucial for accurate coulombic efficiency analysis, shortening test durations and accelerating development cycles.

Recognizing software’s pivotal role in modern battery testing, AVL has developed automation systems like AVL PUMA 2 Battery and AVL LYNX 2. These platforms offer real-time execution of automation, control, and simulation tasks, supporting high-speed control and operation of various test equipment. Their flexibility and compatibility with a broad range of test systems enable seamless integration, enhancing the efficiency of testing processes. Additionally, AVL’s Lab Management Software for Battery Development and Testing optimizes lab operations by tightly controlling thermal and electrical parameters, resulting in more accurate performance analyses.
Dr. Meisner highlighted AVL’s capability to deliver turnkey solutions, including designing and constructing complete battery test facilities. These integrated systems are pre-wired and mounted on frames, allowing for swift deployment at customer sites with minimal setup requirements—merely connecting water and electricity. Looking ahead, AVL is expanding its integrated solutions and advancing software capabilities. The focus is on automated data analytics and the development of battery models that can predict test outcomes, enhancing safety features and reducing testing durations. AVL says this forward-thinking approach underscores its dedication to supporting the rapid evolution of the EV industry through innovative battery testing solutions.
