Battery safety – Focus on thermal runaway and thermal propagation

Online seminar
VA26-01255
Participation fee: €395

The seminar language is German. TThermal runaway, the thermal runaway of a cell, and thermal propagation, the spread of a thermal event from cell to cell in a battery, are among the greatest safety challenges in the operation of lithium-ion batteries, which are now increasingly used in the growing electric mobility segment. The seminar will discuss the basics of thermal runaway and thermal propagation in lithium-ion batteries and present testing and simulation options. In addition, the standards and legal situation regarding thermal propagation will be examined and aspects of functional safety in connection with thermal propagation will be discussed (hazard and risk analysis according to ISO 26262:2019). Information on detection options and the correct handling of lithium-ion batteries will round off the seminar.

On the topic:

Thermal runaway describes an uncontrolled chain reaction within a lithium-ion cell. It can be triggered by mechanical damage, overcharging, internal short circuits or overheating. This causes the temperature to rise so high that further exothermic reactions are triggered – a self-reinforcing process.

The highest safety standards must be met for vehicle occupants/vehicles with lithium-ion batteries. Thermal runaway can lead to life-threatening situations within seconds. Fires involving electric cars receive a lot of media attention. Even a few incidents can severely damage customer confidence. Standards (e.g. UN-ECE R100, UL 2580, IEC 62660) require proof that thermal runaway and thermal propagation are controlled or prevented. Manufacturers are obliged to demonstrate robust testing and protection concepts. Recalls of entire vehicle series due to battery risks are extremely expensive.
