Equivalent Circuit Models
inaccurate and no insights!
complex and slow!
We use a fundamentally different battery modeling approach that combines speed and precision. It is based on the fundamental idea of virtually reproducing all relevant processes inside the battery. This is quite complicated: physical, chemical and thermodynamic processes are coupled in complex ways, depending on operating conditions and age. Everything happens simultaneously and runs on different length and time scales: from electrode particles just a few micrometers in size, up to processes in the centimeter range of cells and the meter range of packs. Some processes take just milliseconds, others need months.
You cannot get far without a battery lab. This includes chemistry labs for cell disassembly, building of custom battery cells, and in-depth in-house analysis capabilities. It is also essential to perform comprehensive battery measurements under any electrical, thermal and mechanical boundary conditions. On this basis, we apply optimized parameterization methods and efficiently identify the model parameters.
We have had hundreds of battery cells in the lab, measured them over the entire operating range, completely disassembled and modeled them. Therefore, we have comprehensive battery data of the entire market: all chemistries, all cell designs, all sizes, all industries.
Fast. Physical. Accurate.
If you can show us another battery cell model that is more accurate, we will refund your money.
