Test System for Lithium Ion Energy Storage Systems

Lithium Ion batteries are a proven technology for automotive applications, with a move towards electric vehicles making the production and ongoing development of lithium-ion energy storage systems a growing industry. When looking at electric car battery testing, battery abuse test chambers for lithium ion batteries need to deliver test conditions to internationally recognised lithium ion battery abuse test standards to ensure the safety of the power banks produced.

Standards developed by the IEC, ISO, SAE, CEN and CENELEC amongst other bodies help regulate battery use in electric vehicles, with an agreement in the EU and US to a Transatlantic Cooperation on Standards for Electric Vehicles to avoid conflicting battery safety standards.

Increasingly larger applications require storage systems that both have a very high energy content and supply a high level of power. Testing of batteries to battery safety standards and classifications, EUCAR hazard level requires the simulation of a range of abusive conditions including overcharging, short circuit, physical deformation, shock temperature changes and other climate conditions such as humidity condition simulations.

Alternative drive systems are a central component of the automotive future. In comparison to other mobile storage systems, lithium ion batteries and fuel cell technology have become established. An energy storage system must be as safe as possible. External loads, e.g., caused by high or low temperatures, fast temperature changes, humidity, mechanical loads or corrosive influences, must not lead to failure or unintended reactions.

During the temperature tests, overload conditions or malfunctions may occur. They could ultimately result in batteries being destroyed. With the ever increasing size of storage systems, the impact of a malfunction becomes larger and the potential danger when testing lithium batteries increases. Therefore, when doing such tests safety in the laboratory, above all personal safety, has the highest priority.

We work together with you to exactly tailor our li-lo test systems of the weisstechnik® and vötschtechnik® brands to your test conditions.

Reliable measurements are ensured by:
