Batemo Technology digitizes
battery development.

We combine the three technoĀ­logĀ­ical assets of battery modeling, battery parameĀ­terĀ­iĀ­zaĀ­tion and battery data. This combiĀ­naĀ­tion makes us unique, worldĀ­wide. Our customers use Batemo simulaĀ­tions to make their battery development faster, lower cost while leading to better products. This is how we generate value and contribute to the success of our customers. Fully in the spirit of our logo: UnderĀ­standing Batteries.

Challenge

Building good batteries is very diffiĀ­cult. It all starts with the battery cell design and the material selecĀ­tion of compoĀ­nents such as electrodes or electrolytes. Then, the individual cells must be optimally connected, tempered and operated in a given instalĀ­laĀ­tion space. They must not age, safety must always be guaranĀ­teed and operaĀ­tion in the overall system must function. In this context, the requireĀ­ments in the various applications of batteries are highly diverse. A battery for a smartĀ­phone is fundaĀ­menĀ­tally different from a battery for an electric vehicle, and again quite different from a battery in a power tool or a stationary storage unit. In addition, battery technology is evolving rapidly. So identical design questions lead to very different answers depending on the appliĀ­caĀ­tion and the point in time. Some example questions are: 

  • How should I design the battery cell for my application?

  • What is the fastest charging strategy for my cell?

  • Which operaĀ­tional strateĀ­gies extent the lifetime of my battery?

  • How does my optimal pack design look like?

  • Which cell is the best for me?

FortuĀ­nately, there is a proven method to deal with this: simulaĀ­tion-based development. In this process, all imporĀ­tant compoĀ­nents are modeled, i.e. digitally mapped in computers, and their dynamic behavior is calcuĀ­lated with simulaĀ­tion. CompreĀ­henĀ­sive simulaĀ­tion studies can thus answer the questions mentioned. 

But there is a problem: This does not work for batteries.

The reason is that batteries are very diffiĀ­cult to model, and the availĀ­able models do not work suffiĀ­ciently well. 

EquivĀ­aĀ­lent Circuit Models

ECM

inaccuĀ­rate and no insights!

EquivĀ­aĀ­lent circuit models (ECM) mimic the terminal behavior of the cell using simple elements like resisĀ­tors, capacĀ­iĀ­tors or other impedĀ­ance elements. The model parameĀ­ters are usually multi-dimenĀ­sional lookup-tables obtained from various measureĀ­ments. Because the fundaĀ­mental model strucĀ­ture does not match the cell physics and since nonlinĀ­earĀ­iĀ­ties are not properly considĀ­ered, ECMs are too inaccurate. 
Using finite element method (FEM) tools, the microstrucĀ­ture of the electrodes is reconĀ­structed and the system of partial differĀ­enĀ­tial equations is solved spatially. This approach is error-prone; parameĀ­terĀ­iĀ­zaĀ­tion takes several months and the model validity must be ensured by you. Moreover, simulaĀ­tions will usually take several hours. This makes the FEM approach too complex and too slow for development. 

MicrostrucĀ­tural Models

Microstructure

complex and slow!

And thatā€™s the challenge: develĀ­oping batteries is an extremely diffiĀ­cult task, and the potenĀ­tial solution of simulaĀ­tion-based development does not workā€¦ until Batemoā€™s technology fundaĀ­menĀ­tally changed that. 

Solution

Our technology enables the consisĀ­tent simulaĀ­tion-based development of batteries so that the above-mentioned challenge is mastered. TechnoĀ­logĀ­iĀ­cally, three things are essential:

Battery
Modeling

We use a fundaĀ­menĀ­tally different battery modeling approach that combines speed and preciĀ­sion. It is based on the fundaĀ­mental idea of virtuĀ­ally reproĀ­ducing all relevant processes inside the battery. This is quite compliĀ­cated: physical, chemical and thermoĀ­dyĀ­namic processes are coupled in complex ways, depending on operating conditions and age. EveryĀ­thing happens simulĀ­taĀ­neĀ­ously and runs on different length and time scales: from electrode partiĀ­cles just a few micromĀ­eĀ­ters in size, up to processes in the centimeter range of cells and the meter range of packs. Some processes take just millisecĀ­onds, others need months.

Parametrization

You cannot get far without a battery lab. This includes chemistry labs for cell disasĀ­sembly, building of custom battery cells, and in-depth in-house analysis capabilĀ­iĀ­ties. It is also essenĀ­tial to perform compreĀ­henĀ­sive battery measureĀ­ments under any electrical, thermal and mechanĀ­ical boundary conditions. On this basis, we apply optimized parameĀ­terĀ­iĀ­zaĀ­tion methods and efficiently identify the model parameters.

Batemo is the only one to own the combiĀ­naĀ­tion of these three technoĀ­logĀ­ical assets, which is why we are able to offer breakĀ­through products that are unique worldĀ­wide, and why we actively shape the future of battery development - everyday. To do modeling in an indusĀ­trial environĀ­ment, in the essence, a simulaĀ­tion tool needs to fulfill three key criteria:

Fast. Physical. Accurate.

This is what we promise to our customers: EveryĀ­thing we do or we sell must be as fast, as physical and as accurate as possible. And we put our money where our mouth is and guarantee:

If you can show us another battery cell model that is more accurate, we will refund your money.

show the rules

The model accuracy is calcuĀ­lated from a set of validaĀ­tion experĀ­iĀ­ments that cover the total operaĀ­tional area of the cell as speciĀ­fied by the cell manufacĀ­turer. Additional validaĀ­tion measureĀ­ments in the interĀ­poĀ­laĀ­tion and extrapĀ­oĀ­laĀ­tion regime, that are unknown to the model creator, are used for additional testing of the model. The ratio of the measureĀ­ment time between the different validaĀ­tion sets is as follows: validaĀ­tion set known to Batemo and competitor 50%, validaĀ­tion set known only to Batemo and unknown to competitor 25%, validaĀ­tion only know to competitor and unknown to Batemo 25%. Model accuraĀ­cies are defined and averaged as defined in the Batemo validaĀ­tion Excel documents.
