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 automotive 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.
Our AVL solution measures all important parameters under different environmental conditions. Further, it is equipped with multifunctional interfaces connecting to additional tools necessary for battery testing. The combination of development services for the customer and the independent development of test equipment provides AVL with a holistic view of the challenges faced in the domain of battery testing.
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.”
