Employing virtual development to understand and inhibit thermal runaway propagation in lithium-ion battery systems

AVL’s virtual development approach to understand and inhibit a thermal runaway propagation in lithium-ion battery systems
Thermal Runaway

The answer to a central question is crucial for the development of safe high-quality batteries: How long can and must a battery withstand a thermal runaway of a cell?A continuous cell has three possibilities to get rid of its energy: First, the conductive heat conduction, which can be inhibited by insulation measures. Secondly, the discharge of hot gases, which can be passed through the gas duct and expansion spaces inside the battery to cool down. And finally, the emission of electrode particles, which in turn have to be kept away from other cells and electrical lines.In this webinar Daniele Suzzi and Bernhard Brunnsteiner will give you insights on how AVL developed a number of virtual methods to fully analyze all of the processes mentioned. These methods are successfully used by our customers to determine and optimize the maximum safety time for parking and leaving a battery electric vehicle.Key take-aways

• Comprehensive simulation approach for increasing passive battery safety in case of thermal runaway

• Virtual verification of effeteness of design counter measure against thermal propagation

• Efficient test specification and test result analysis supported by simulation

• Method for proper layout of burst discsBack to Webinar Series Battery
