I-Detekt

Intelligent battery protection system for electric vehicles for detection
of undesired mechanical damage

In the I-Detekt project, an intelligent battery protection structure for electric Period
vehicles made of glass-fibre reinforced plastic is being developed. This can 01.12.2020 – 30.11.2023
be used to automatically detect and classify relevant damage to the overlying
battery module. Thanks to a structure-integrated sensor system, it is also pos- Project management
