LOGEbat – Virtual Battery
The aim of the project is to describe and predict the electrochemical and physical processes in batteries using the LOGEbat software. In particular, the aging of the batteries is to be taken into account.
Within the scope of the project, the effect of various aging processes of lithium-ion batteries and other batteries on the available capacity as well as the short-term and long-term safety of the batteries was investigated. The aim of the project is to build up an in-depth understanding of the safety and aging-relevant physical and chemical processes involved, especially in lithium-ion batteries (LIBs). In this way, critical operating conditions and critical design parameters will be identified.
The result is a modeling tool that can be used to derive optimized operating strategies based on detailed chemistry.

Pseudo-2D model:
Solid material (positive and negative electrode) is modelled with particles. The particles are symmetrical and have the same radius Rp. A diffusion model takes into account the availability of active material on the surface.
The following parameters can be analysed with LOGEbat:
- Cell temperature
- Cell potential (SOC)
- Voltage, current and capacity
- Internal resistance
- Charging time
- Decrease in the available cell capacity and cyclical performance of the battery cell
Graphical user interface:
- Simple interfaces to input data etc.
- Purpose-orientated layout
- Easy, intuitive operation
- Graphical post-processing of results
