OEMs, battery, and cell suppliers have to continuously develop new packs and cells for the evolving automotive market. For battery electric vehicles (BEVs), the mileage range is a key factor, making the capacity of battery cells and packs crucial. Besides capacity, current and voltage are central to battery development. As a result, the test systems for validating battery cells and packs need to be state-of-the-art.
From individual test products to integrated system solutions and complete battery test facilities, you have come to the right place for battery test expertise. Our software and hardware portfolio is complemented by holistic support options and application service.
Testing Battery Cells
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 TS™. We also offer software solutions for running entire laboratories with several thousand cell test channels via AVL Lab Management™ for Battery.
Testing Battery Modules and Packs
OEMs and battery suppliers have to continuously develop new packs for the evolving mobility market. For battery electric vehicles (BEVs), the mileage range is a key factor, making the capacity of battery cells and packs crucial. In addition to capacity, current and voltage are central to battery development. As a result, the test systems for validating battery packs need to be state-of-the-art.
We offer advanced solutions for battery pack and module testing, including containerized and modular test systems. Our technology measures all critical parameters under various environmental conditions and features multifunctional interfaces for seamless integration with additional testing tools. By combining customer-focused development services with independent test equipment innovation, AVL provides a holistic approach to addressing the challenges of battery testing.
AVL has developed battery cell cyclers (AVL CELL TESTER™) to improve and accelerate electric vehicle development. These bi-directional, multi-channel DC power supplies test, diagnose, characterize, and validate battery cells, achieving output currents from ±2 A to ±2,400 A. The Cell Tester uses a unique current measurement technique for best-in-class accuracy (0.01% of actual value) among high current cell cyclers. This reduces test programming complexity, ensures consistent accuracy, and provides reliable results. It also reduces test time through accurate coulombic efficiency analysis. → Learn more
Testing the Integration of High-Voltage Components
High-voltage systems are complex and dangerous if not properly designed and tested. The AVL HV System TS™ E-Integration provides a safe environment to test HV systems, which helps to prevent accidents and injuries. Besides that, cost-effectiveness is very important. Testing HV systems in a real-world environment can be expensive, time-consuming, and risky. The AVL HV System testbed provides a cost-effective way, without the need of a chassis dyno, to test HV systems before they are implemented in vehicles, which can help to reduce development time and costs.
Testing the Charging and Discharging of Electric Vehicles
New charging standards and norms regarding connections, communication, safety, etc. had to be established between OEMs and the industry in recent years. It is desirable to move charging test activities to a controlled test environment to reduce test costs, accelerate development, improve V&V, and enhance quality and customer experience. Simulated charging enables testing of various communication protocols as well as misuse or failures/ malfunctions of charging stations. For AC charging, different mains supplies can be tested depending on the region, e.g. JP, US and EU.
When it comes to batteries, there are countless opportunities to find the right development partners and manufacturers. Here, nuances decide to prevail in the market. As a globally positioned company with knowledge from battery development, simulation and production, AVL is the reliable and competent partner in the field of test systems for batteries.”

Data- and process management software for cell, pack, and module
AVL is pioneering a novel battery cell conditioning method designed for ultra-high precision coulometry (UHPC) measurements. This innovative approach optimizes battery testing by tightly controlling thermal and electrical parameters, resulting in more accurate performance analysis.
The AVL Customer Services organization consists of more than 700 service- and application engineers worldwide, operating from more than 50 locations. Our global footprint is your local benefit.
In addition to the on-board charger and the battery itself, most control units are also involved in charging the battery. With increasingly connected vehicles, the vehicle will need to communicate with many different types of charging stations and, in the near future, even directly with the power grid (for load balancing).
Thanks to AVL affiliates all over the world we are close to our customers with a global footprint. With our experience from different customer types, like battery, vehicle or energy storage manufacturers, we are able to continuously improve our test systems. New entrants as well as well experienced OEMs and Tier 1 and Tier 2 suppliers and test institutes rely on the support of the global AVL network. Our affiliates represent AVL directly on customer site.
