BATTERY SAFETY
Increased possibilities, increased protection
The change to electromobility comes with
a debate about safety. How will batteries behave
in extreme usage? What affects their level
of safety? What happens in the case of a crash?
What opportunities are there for optimization?
To answer questions like these thoroughly, we
have developed a comprehensive “toolbox” for
battery safety. With our studies, tests, simulations
and standardization procedures, we are
able to ensure that our high-voltage batteries
meet the highest safety standards in all respects.
DEVELOPMENT OBJECTIVE: NO PROPAGATION
Among the biggest battery safety challenges are thermal runaway effects.
Thermal runaway is an uncontrolled, self-enforcing rise in a cell’s temperature
and its propagation. Thermal runaways can be triggered by specific
abuse tests. However, in the worst-case scenario, this can also occur on the
road. It leads to a rapid release of energy, right through to a complete combustion
of the cell. In addition to massive overheating of the components,
this also results in the emission of hot gas or hot electrode particles. To thoroughly
analyze these scenarios, we have developed a series of virtual methods.
Forming the basis for these are deflagration tests in a secured test en-
