Numerous models of electric vehicles in the automotive market are clear proof of being a solution for the massive reduction of greenhouse gases, caused by the high number of the internal combustion engines in the transport sector. It was observed that by developing and using electric vehicles, the quantities of harmful emissions in large cities can be significantly reduced. The convenience of users of electric vehicles have pushed the researchers to study in more detail and attention the storage of energy in the energy sources used in the construction of electric vehicles. Several researchers have used the resulted data to develop finite element models, therefore it is necessary to study their behaviour. The article presents an experimental research, regarding the analysis of the behaviour and prismatic cell of type LiFePo4 at different mechanical stresses, including three-point bending, lateral bending, indentation with hemispherical punch and pinch indentation. The cell was tested at ambient temperature at 90% SOC.
