Batemo Cells are the most accurate battery cell models.

Our Promise:
If you can show us another battery cell model that is more accurate, we will refund your money!

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. 

A Bate­mo Cell is a high-pre­ci­sion, phys­i­cal sim­u­la­tion mod­el of a lithi­um-ion bat­tery. Through opti­mized para­me­ter­i­za­tion meth­ods, we eas­i­ly and quick­ly cre­ate Bate­mo Cells for all type of cells and chemistries. With a flex­i­ble inter­face and sim­u­la­tion times of sec­onds, the Bate­mo Cells inte­grate seam­less­ly into your research and devel­op­ment processes.



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



Bate­mo Cells do not sim­ply mim­ic 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. 


Research and devel­op­ment in indus­try can only rely on sim­u­la­tion-based devel­op­ment process­es if the under­ly­ing mod­els are valid. That is why we cre­ate every Bate­mo Cell specif­i­cal­ly for the respec­tive cell type and chem­istry. We always prove the valid­i­ty of our Bate­mo Cells through exten­sive mea­sure­ments that quan­ti­fy the Bate­mo Cell accuracy.


There are two pos­si­ble ways for you to get the Bate­mo Cells you need: You can either get the Bate­mo Cell Library that con­tains mod­els for the most com­mon bat­tery cells on the mar­ket. Or you can choose for us to cre­ate a cus­tom Bate­mo Cell exclu­sive­ly for you.

Do your have your own cell? We will devel­op a mod­el exclu­sive­ly for you.

Bate­mo Cells can be inte­grat­ed into dif­fer­ent sim­u­la­tion envi­ron­ments. Built-in inte­gra­tion is avail­able for MATLAB Simulink and Simscape. Addi­tion­al­ly, Bate­mo Cell FMUs allow inte­gra­tion into many oth­er sim­u­la­tion tools.


Mod­el­ing your bat­tery sys­tems with Bate­mo Cells is easy. Just like the real bat­tery cell, the Bate­mo Cell has an elec­tri­cal and a ther­mal inter­face. The inter­face is designed so as to make inte­gra­tion of the Bate­mo Cells into your mod­els straight-for­ward: You can either sup­ply the ter­mi­nal cur­rent or the ter­mi­nal volt­age as elec­tri­cal bound­ary con­di­tion and the sur­face heat cur­rent or the sur­face tem­per­a­ture as ther­mal bound­ary con­di­tion. Set­ting ini­tial con­di­tions is intu­itive and com­fort­able using the Bate­mo Cell block mask.

Through sim­u­la­tion, the Bate­mo Cell cal­cu­lates every­thing you need: Not only the data that you can also mea­sure in the lab­o­ra­to­ry but addi­tion­al inter­nal quan­ti­ties that are high­ly rel­e­vant in bat­tery sys­tem design such as the inner cell tem­per­a­ture or the anode and cath­ode elec­trode sur­face potentials.

To give you an easy start, we have record­ed video tuto­ri­als that intro­duce all fea­tures and show best-prac­tice exam­ples of typ­i­cal design chal­lenges. Three examples:

  • Pack Design: In your appli­ca­tion, you con­nect cells in par­al­lel and in series to a bat­tery pack. With your Bate­mo Cells, you can do the same and then obtain a deep insight about what hap­pens in your pack.

  • Fast-Charg­ing: Devel­op strate­gies that charge your cells as fast as phys­i­cal­ly pos­si­ble with­out aging your cells through lithium-plating.

  • BMS Design: Devel­op your state and para­me­ter esti­ma­tors with the sup­port of a glob­al­ly valid phys­i­cal mod­el. Ana­lyze how aging and non-lin­ear cell behav­ior influ­ences the robust­ness of your methods.

There are a lot more pos­si­bil­i­ties and you can learn about oth­er exam­ples here. More­over, you can enhance your Bate­mo Cells through add-ons.


  • Aging and Parameter Studies

    The aging and life­time of bat­ter­ies rep­re­sent huge chal­lenges in bat­tery sys­tem design. This add-on allows you to age both the cell capac­i­ties and pow­er per­for­mance in exact­ly the same way as it hap­pens in the real cell. Addi­tion­al­ly, the influ­ences of pro­duc­tion vari­a­tions can be includ­ed to your mod­els through this add-on.

  • Power and Energy

    When you devel­op ener­gy-effi­cient oper­a­tional strate­gies or need the ther­mal loss­es of the cell to be pre­cise, this add-on is made for you. It sup­plies all cell pow­ers, ener­gies and efficiencies.

  • Anode and Cathode

    This add-on sup­plies inner data for the state of the anode and cath­ode. This is some­thing quite amaz­ing: With this add-on, you can detect lithi­um plat­ing and thus devel­op oper­a­tional strate­gies that avoid cell aging and safe­ty-crit­i­cal oper­a­tion points.


You can buy per­pet­u­al or rental licens­es, choose what­ev­er best suits your needs. We are very flex­i­ble and it is pos­si­ble to com­bine dif­fer­ent licens­es. Of course, your per­pet­u­al or rental licens­es can include a soft­ware main­te­nance ser­vice so as to receive con­tin­u­ous updates and sup­port. To get access to Bate­mo Cells there are two ways:

  • Bate­mo Cell Library: The license is only required once for your com­pa­ny and grants access to the total Bate­mo Cell Library includ­ing reg­u­lar updates with new cells.
  • Bate­mo Cell Cus­tom: You sim­ply pay once for the cre­ation of the Bate­mo Cell. Then you can use it in the whole company.

To start a sim­u­la­tion with one or mul­ti­ple Bate­mo Cells, you also need the Bate­mo Cell Run­time license. If you enable add-on fea­tures you also will need the respec­tive add-on license. We offer dif­fer­ent license types:

  • Con­cur­rent: This license floats in your net­work and can be used by any­one with­in your company.
  • Named User: This license enti­tles one named user to sim­u­late the Bate­mo Cells with one nat­ur­al per­son being assigned to the named user.
  • Des­ig­nat­ed Com­put­er: The license enti­tles the sim­u­la­tion of Bate­mo Cells on a sin­gle reg­is­tered com­put­er. You must ensure that only one nat­ur­al per­son has access to the des­ig­nat­ed com­put­er at any time.
