Compur - Battery Testing Station
In future more and more automobiles shall have electric motors. Drivers will appreciate battery driven cars only, if they are 100 % suitable for dayly use. Therefore innovative, robust and safe energy storage devices with high capacity are needed. Todays most used batteries contain Lithium. Transportation of more than 3 g respectively 0,1 oz Lithium is regulated, because Lithium is a very reactive element. Before car industry incorporates half a ton of Lithium batteries into a vehicle, this battery must undergo severe endurance testing.

No wonder industry is strongly investing in battery development and battery testing. Before a battery goes onto the street it must prove that it can endure all kinds of stress: Heat, mechanic stress, electric stress, aging…
Stress testing means, the specimen may be destroyed. A destroyed Lithium battery can release as well toxic as explosive gases. In order to protect personell and environment, some of the testing stations must have a gas detection system.
In order to quantify the risk, there is the so called EUCAR Hazard Standard. EUCAR (European Council for Automotive R&D) classifies the risk by defining the potential impact on people and environment. The highest risk class requires a gas detection system to be on board.
In cooperation with the car industry Compur Monitors has devlopped an extractive gas detection system suitable exactly for this application.
Testing of Car Batteries
The use of batteries in vehicles requires utmost safety and robustness. Therefore prototypes and specimen of the running production must undergo intense testing. Battery testing stations consist of two components. The testing compartment itself – this can be a metal table, a separate room or a container, and a control device, normally a laptop or computer. For safety reasons these two components are located in separate rooms.
The most important component is of course the testing station itself. Here the specimen can be exposed to electrical, mechanical and / or heat stress. The measured values are transmitted to the control device, where they are evaluated and stored. It is essential that the control device is in a separate room, because batteries stressed to the limit can be very dangerous.
As an option there can be extra safety installations such as access control devices, locking systems, gas detectors and automatic extinguishing systems.
