CellMod

What is CellMod?

CellMod Virtual Battery is the first virtual lithium-ion battery capable of predicting cell and packaging behavior, including thermal behavior, with an accuracy greater than 97%.

Based on an early-principle electrochemical model, CellMod is packaged as a Functional Markup Unit (FMU), allowing it to be easily integrated into most major simulation packages, such as Altair Activate, through the open industry standard FMI (Functional Mockup Interface). CellMod FMU accepts as current input, room temperature and time interval and will emit voltage, internal cell temperature, SOC and any other cell internal state variable.

Unlike the simple equivalent circuit (CE) models currently used, CellMod FMU takes into account the physical processes that occur within cells, such as diffusion in solids, diffusion in electrolytic solution, reaction kinetics, charge transport, heat transport, CellMod can predict the behavior of battery cells with a high degree of accuracy.

The standard battery model for CellMod is the Panasonic NCR18650A. This version can be used as a replacement representing a "generic" lithium ion battery and yet provide better accuracy than that offered by a simple equivalent circuit model. For project teams that require a high level of accuracy (~ 97% or accuracy at the level of statistical variation) of specific cell versions to represent any type of lithium ion cell, from NMC and LMO to LFP and NCA, and all iterations of those cells can be quickly developed.

BasicPackMod

FMU BasicPackMod uses the same advanced model as FMU CellMod and allows users to specify the number of cells in series and in parallel. Thermal inputs and outputs are not provided.

Key features and benefits

Ability to quickly integrate a precise virtual battery into any design.

Packing sizing

Using CellMod's associated FMU, BasicPackMod, the packaging size can be easily affected.

Development of Power and Power Control Function

Sendyne's Celly FMU will interface through the IMF with any IMF-enabled simulation platform to provide the essential materials for evaluating performance and developing thermal and energy management functions.

Looped hardware and software

The Sendyne CellMod FMU Virtual Battery can provide more realistic battery inputs for software and hardware in loop applications.

Thermal Simulation Pack

The Sendyne CellMod FMU Virtual Battery will interface with cfd software for thermal packaging design. In addition, it will provide a real-time energy, energy and thermal simulation for the development of cooling control.

Cell selection and accelerated testing

CellMod FMU accuracy enables accelerated cell testing and selection, comparing FMUs optimized for individual cells in various environmental and load conditions.

Online battery forecast

CellMod FMU's speed, small code size, and memory management capabilities enable its use in embedded applications.

Industrial Applications

CellMod FMU and BasicPackMod can be used in many applications and industries, including automotive and land transportation, heavy industry, aerospace and e-mobility, or any application that uses a battery. FMU CellMod's capabilities cover a wide range of applications within these industries, including electric vehicles, buses, airplanes, bicycles. that allow designers to perform package sizing, cell selection, hil, SIL, and battery system management development. A typical designer can test virtually as if the actual cells were being tested. This not only saves significant time and money, but CellMod is highly accurate, it improves system performance; all this can be accomplished in Altair Activate.
