We specialize in high-precision simulation software for lithium-ion-batteries. Smartphones, power tools or e-bikes – our software solves central challenges of battery system development. Typical design questions that can be quickly answered include:

  • Which cell technology is most suitable for a specific application?
  • What does an optimal pack design look like?
  • Which operational strategy extends the lifetime of the battery?
  • How can innovative fast charging methods be developed?
  • How can safety be guaranteed in complex systems, under all circumstances?


Our software is based on the fundamental idea of precisely describing and virtually reproducing all relevant processes in lithium-ion-batteries. This is very 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 cell and pack size. Some processes take just milliseconds, others need months.


Our customers receive our models as customized software for their familiar development environment. Through optimized parameterization methods, we easily and quickly adapt our models to customer-specific cells and demonstrate validity. With a flexible interface and simulation times of seconds, our software integrates seamlessly into our customers’ industrial research and development processes.

cell models

Our models do not simply imitate cell behavior, but precisely describe all relevant physical processes, even under extreme conditions where conventional models fail: under high currents, at low state of charge, and within the entire temperature range.


Our software provides highly relevant information for battery system development that cannot be obtained in other ways. Examples include the temperature and state-of-charge distribution of the cell or the half-cell potentials. Knowledge of these quantities enables targeted prevention of aging, such as by lithium plating.

aging mechanisms

Our models consider different aging mechanisms and are able to realistically predict the behavior of aged cells.


Research and development in industry can only rely on simulation-based processes if the underlying models are valid. That is why we always prove the validity of our models for customers’ cells and perform extensive measurements to quantify model accuracy.


We parameterize our models quickly and easily, specifically for the customer’s cells.


Working with our software is easy and intuitive. A graphical interface allows the battery expert, the system engineer, and the intern to efficiently answer complex questions.


The integration of our models into the development environment of our customers is straight-forward. Using flexible interfaces, initial and boundary conditions can be specified as desired. Thus, our model allows a wide variaty of simulations.

simulation times

Our models run on normal office computers within seconds. Waiting for battery simulation results is a thing of the past!


As a start-up company, we work for select leading customers in Germany. Our customers use our software as virtual batteries and save time-consuming and lengthy measurements. Their battery system development is model-based, making it faster, safer, more flexible, and leading to better products. This is how we contribute to the success of our customers.


With our software, the innovation potential of new ideas can be easily evaluated and complex functions can be developed much quicker. This is how our customers enhance their technological leadership.


Our customers monitor their batteries during operation. They develop the safety features with our software, detect critical conditions early, and design efficient strategies to ensure safe operation under all conditions.

charging methods

Fast battery charging is used in many applications, where the batteries must not be damaged. Our customers develop minimal-aging, fast-charging methods for their battery packs using our software.

cope with

Battery packs are often used in a variety of products with different chargers. Using simulations, our customers can ensure overall compatibility.

market share

Our customers are introducing new technologies to the market. Our software helps to bring high-quality, innovative ideas to the market very quickly. Key product features can be improved and differentiated from competitors, leading to increased market share.

speed up

Our simulations are significantly faster than real-time laboratory tests. Our customers perform comprehensive, simulation-based test scenarios with single cells, battery packs, or total systems in a fraction of the time.


With our software, single functions or subsystems can be thoroughly tested in the early stages of the development process. Our customers detect design errors early on and significantly reduce the failure rate of their design and production validation.


Our software reduces the cost of battery system development in many ways. For instance, our customers reduce expenses on prototyping, avoid performing extensive lab measurements, and decrease their development time.

Batemo GmbH was founded and self-financed by Dr.-Ing. Michael Schönleber and Dr.-Ing. Jan Richter in Karlsruhe, Germany, in March 2017. The founders:

Dr.-Ing. Jan Richter studied electrical engineering and information technology at the Karlsruhe Institute of Technology (KIT). He focused on electric mobility and the fields of electrochemical energy storage, power electronics, and electrical machines. During his studies, he spent half a year working in the Dalian Institute of Chemical Physics in China and for Mercedes-Benz Research & Development North America in the USA.
He completed his doctorate at the Institute of Electrical Engineering (ETI) at KIT, graduating summa cum laude, on modelling, parameter identification and control of highly-utilized synchronous machines. He received the PCIM Young Engineer Award for his research. As part of his activities, he developed a model-based development tool for power electronics and electrical machines for a Tier-1 automotive supplier. During his undergraduate and graduate studies, he received a scholarship from the Studienstiftung des deutschen Volkes.

Dr.-Ing. Michael Schönleber studied electrical engineering and information technology at the Karlsruhe Institute of Technology (KIT). He specialized on electrochemistry and system theory, with a focus on lithium-ion-batteries. During his studies, he spent a year working for Robert Bosch LLC in the USA. He was honored with the Continental Auto-Motivated Award and recognized as top student of his year with the Siemens Energy Award.
He completed his doctorate at the Institute for Materials in Electrical Engineering (IAM-WET) at KIT, graduating summa cum laude. He researched the low frequency behavior of NMC cathodes and aging of lithium-ion-batteries in an industry project with an automotive manufacturer. For his doctoral thesis, he received the Carl Freudenberg Prize.
