The key to unlocking peak perfor­mance of battery systems lies in the intri­cate dance of robust SOX estima­tors and a finely tuned opera­ting strategy. It’s about exten­ding battery life and enhan­cing user experi­ence.
At Batemo, we believe that a valid plant model for software-in-the-loop methods is the golden ticket to compre­hen­si­vely assess Battery Manage­ment Systems (BMS) functions across various opera­tion condi­tions and battery aging states.

Local inhomo­genei­ties can trigger aging and safety issues within a cell. But how do you detect and predict these critical hot spots and opera­ting condi­tions? With the Batemo Cube Model.
It allows for custom discretiza­tion of the cell interior and subse­quent simula­tive predic­tion of all relevant inner quanti­ties. Identify and under­stand spati­ally resolved effects and derive optimal design solutions and cooling concepts – without lengthy measurements.

We are thrilled to announce the addition of three new battery cells to the Batemo Cell Explorer, our ever-growing library of physical, parame­trized and globally valid battery cell models. These include 18650 cylind­rical cells from #Panasonic, #EVEEn­ergy and #DMEGC, all with energy densi­ties greater than 600 Wh/l.
Stay tuned for more exciting additions, as we are committed to keep our library as compre­hen­sive as it gets by frequently pushing updates with hot candi­date cells.

Lithium plating is the showstopper for fast charging, causing rapid cell aging and safety risks. Since experi­mental plating detec­tion is challen­ging, it often comes down to tedious cycling tests. The solution is getting access to the anode surface poten­tial inside the cell under all opera­tion condi­tions, which is the trigge­ring quantity for lithium plating. And this is exactly what our physical, parame­ter­ized and validated model can do for you.

LFP cells are true drivers of innova­tion and are already today very hot candi­dates for statio­nary energy storage, rail appli­ca­tions and automo­tive. Compared to conven­tional NMC/NCA cathode materials, LFP cells also have an improved environ­mental balance due to the absence of the critical materials nickel and cobalt, and their extended lifespan reduces waste.
Check out their perfor­mance in our Cell Explorer or read more in our LinkedIn post.

Maybe you have already seen the YouTube videos from Munro & Associates or Jerry­Ri­gE­ver­y­thing, where they disas­semble the battery pack of the Rivian R1T. There are 7.777 cells inside the Rivian, but what does a single cell bring to the table? With an energy density of 262 Wh/kg and nominal capacity of 4.80 Ah, they are good performing, but do not outrange some other cells we have already measured.

Making valid predic­tions of cell perfor­mance for various cell designs is a diffi­cult task… At Batemo, we do that daily!
By varia­tion of active layer and current collec­tors thick­nesses e.g., you can reach diffe­rent energy densi­ties, power densi­ties and charging times.
Now, selec­ting the best cell design is straight-forward.
