Sendyne Introduces First Li-Ion Battery Simulation Tool That Can Predict Cell & Pack Behavior With an Accuracy Better Than 5%

Sendyne Corp., the leader in sensing, modeling/simulation, and control products, announces the immediate availability of CellMod, the first Li-Ion battery simulation tool that can predict cell and pack behavior with an accuracy of better than 5% under a wide range of test conditions. The software includes Sendyne’s Pseudo-2D compact physics-based Li-Ion battery cell model coupled with Sendyne’s proprietary dtSolve™, a tool that executes several orders of magnitude faster than other commercially available numerical solvers. The software may be used as a standalone tool or can be integrated with other simulation packages for whole system co-simulation via the Functional Mockup Interface (FMI), an open standard supported by all major simulation platforms.

CellMod can be quickly adapted to represent any type of Li-Ion cells, from NMC and LMO to LFP and NCA, and all iterations of these cells. To achieve this, only a simple (non-proprietary) set of experimental data on the cell to be modeled is needed. Sendyne’s tool kit, which includes state of the art parameter extraction, then creates a unique CellMod version for a specific cell. All unique CellMod versions are created under NDA.

Reduce Design Time and Cost

Currently deployed by a Tier-1 U.S. battery maker, CellMod’s uses include battery cell rapid prototyping. This reduces design time and costs, as each cell design can first be tested using the model. Design makers can utilize the model to select cells and vendors based on how well candidate cells perform in particular applications.

Further, CellMod can help reduce cost, a major challenge to large scale battery adoption. The compact nature of the CellMod-dtSolve™ bundle allows it to be embedded on a microcontroller within a Battery Management…
