Batemo Technology digitizes
battery development.

We combine the three techno­log­ical assets of battery modeling, battery parame­ter­i­za­tion and battery data. This combi­na­tion makes us unique, world­wide. Our customers use Batemo simula­tions 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: Under­standing Batteries.

Challenge

Building good batteries is very diffi­cult. It all starts with the battery cell design and the material selec­tion of compo­nents such as electrodes or electrolytes. Then, the individual cells must be optimally connected, tempered and operated in a given instal­la­tion space. They must not age, safety must always be guaran­teed and opera­tion in the overall system must function. In this context, the require­ments in the various applications of batteries are highly diverse. A battery for a smart­phone is funda­men­tally 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 appli­ca­tion 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 opera­tional strate­gies extent the lifetime of my battery?

  • How does my optimal pack design look like?

  • Which cell is the best for me?

Fortu­nately, there is a proven method to deal with this: simula­tion-based development. In this process, all impor­tant compo­nents are modeled, i.e. digitally mapped in computers, and their dynamic behavior is calcu­lated with simula­tion. Compre­hen­sive simula­tion 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 diffi­cult to model, and the avail­able models do not work suffi­ciently well. 

Equiv­a­lent Circuit Models

ECM

inaccu­rate and no insights!

Equiv­a­lent circuit models (ECM) mimic the terminal behavior of the cell using simple elements like resis­tors, capac­i­tors or other imped­ance elements. The model parame­ters are usually multi-dimen­sional lookup-tables obtained from various measure­ments. Because the funda­mental model struc­ture does not match the cell physics and since nonlin­ear­i­ties are not properly consid­ered, ECMs are too inaccurate. 
Using finite element method (FEM) tools, the microstruc­ture of the electrodes is recon­structed and the system of partial differ­en­tial equations is solved spatially. This approach is error-prone; parame­ter­i­za­tion takes several months and the model validity must be ensured by you. Moreover, simula­tions will usually take several hours. This makes the FEM approach too complex and too slow for development. 

Microstruc­tural Models

Microstructure

complex and slow!

And that’s the challenge: devel­oping batteries is an extremely diffi­cult task, and the poten­tial solution of simula­tion-based development does not work… until Batemo’s technology funda­men­tally changed that. 

Solution

Our technology enables the consis­tent simula­tion-based development of batteries so that the above-mentioned challenge is mastered. Techno­log­i­cally, three things are essential: 
Get the Physics Right!

Battery
Modeling

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.

Get the Parame­ters Right!

Parametrization

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.

Batemo is the only one to own the combi­na­tion of these three techno­log­ical assets, which is why we are able to offer break­through products that are unique world­wide, and why we actively shape the future of battery development - everyday. To do modeling in an indus­trial environ­ment, in the essence, a simula­tion tool needs to fulfill three key criteria:

Fast. Physical. Accurate.

This is what we promise to our customers: Every­thing 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 calcu­lated from a set of valida­tion exper­i­ments that cover the total opera­tional area of the cell as speci­fied by the cell manufac­turer. Additional valida­tion measure­ments in the inter­po­la­tion and extrap­o­la­tion regime, that are unknown to the model creator, are used for additional testing of the model. The ratio of the measure­ment time between the different valida­tion sets is as follows: valida­tion set known to Batemo and competitor 50%, valida­tion set known only to Batemo and unknown to competitor 25%, valida­tion only know to competitor and unknown to Batemo 25%. Model accura­cies are defined and averaged as defined in the Batemo valida­tion Excel documents. 
Many high-profile customers from different indus­tries trust us. Take a look what they say about batemo.
Our solutions solve major challenges across the entire battery development process. This starts with the Batemo Cell Designer in the very small with electrode parti­cles and materials up to the complete battery cell design. With the Batemo Cell Model and the Batemo Cube Model, we deal with single cells and address battery system challenges. Data is impor­tant along the entire development chain, which is why we offer compre­hen­sive infor­ma­tion for numerous cells with the Batemo Cell Data and the Batemo Cell Report packages.
