Simcenter BDS - Design battery cell pack using an integrated simulation solution
Simcenter Battery Design Studio supports engineers in digitally validate Li-ion cell design thanks to details geometrical cell specifications and cell performance simulation. Extensive components of a battery cell are available, as well as a material database to support your model development.
Simcenter BDS offers several levels of performance models: a physics-based macro-homogeneous model to get insights into the cell’s electrochemical mechanisms; and an equivalent RCR circuit model, which is an empirical approach to modeling the cell’s behavior in a very computationally effective way.
Simcenter Battery Design Studio (BDS) is an excellent tool for digital Li-ion battery design. In the program it is possible to specify in detail the characteristics of individual battery cells. The software includes an extensive library of battery cells with material properties, which is essential for the design phase of batteries and battery packs.
Why Simcenter Battery Design Studio? 
- Physical description of cells using parameterized GUI environment : Simcenter Battery Design Studio offers standardized battery component specifications. Each battery component can be defined in detail.- Integrated environment for battery design and simulation : Simcenter BDS offers several levels of performance models - macro-homogeneous models allow insight into cell electrochemistry. It is possible to simulate eg the mechanism of voltage loss during the duty cycle or to calculate the heat distribution on the electrode.- Solve complex multi-physical tasks through easy integration with Simcenter STAR-CCM + : For connection with Simcenter STAR-CCM + software, a TBM file is generated, by means of which it is possible to calculate the electro-thermal simulation of the whole battery module.- Design Exploration - Automatic optimization of the design and performance of battery cells : Already in the initial design phase, it is possible to identify how the thermal properties of the battery packs can be improved, which may not always be optimal due to the inefficient distribution of the cooling medium. Poor battery cooling can affect the electrical performance of overheated cells or the overall life of the cell (and the associated safety).- Easy integration with system simulations : The empirical creation model in Simcenter BDS allows you to export the necessary parameters for modeling the entire system (which can be done eg in Simcenter Amesim). The behavior of the designed battery pack can then be assessed in simulating entire systems, eg for an electric rail vehicle, an aircraft, or a smart house.
Uses of Battery Design Studio: a) Compute important attributes of a new cell designs, such as nominal capacity, open circuit voltage or total mass, using the electrode dimensions and electrochemistry parameters b) Understand the sensitivity of a defined cell to the manufacturing variability of underlying parameters, e.g. variable electrode porosity or active particle size c) Simulate the electrochemical response of a cell to a given load, whether power or current, and optimise a design to reduce the total mass or improve the capacity of the cell d) Understand and visualise the underlying phenomena that limit the rate capability or capacity of a cell design, which may be a limitation of the active material, electrolyte or current path e) Create equivalent circuit models, which capture the response to load of a tested cell, by reading in test data and automatically regressing parameters to populate the circuit model f) Finally, complete a cell design which can then be passed to STAR-CCM+ to represent the cell in a detailed three-dimensional model. It can also be multiplied to create a module or pack

Simcenter SPEED offers a complete solution for electric machine design motoring and generating, covering a wide range of electric machines types. Simcenter™ SPEED includes all the necessary theoretical and physical models for a rapid e-machine design with a flexible approach. It combines the following methods to balance calculation speed and accuracy: a) Analytical methods for almost instan- taneous results, making it attractive for those using design exploration programs (for example, HEEDS™ soft- ware) or performing what-if studies b) Quick and smart usage of 2D finite element (FE) magnetostatic analysis to more precisely model magnetic saturated regions
The Simcenter SPEED suite supports the following e-machine types in its various individual programs: a) PC-BDC: Synchronous machine; permanent magnet (PM) surface, PM bread-loaf, IPM, spoke PM, PM inset, reluctance, wound field, interior and exterior rotor, single-, 2-, 3- and multi-phase machines b) PC-IMD: Induction machine; all standard bar types, wound field, interior and exterior rotor, single-, 2-, 3-phase c) PC-SRD: Switched reluctance machine; all standard rotor types, interior and exterior d) PC-DCM: Brushed PM-direct current (DC) machines; all standard PM brushed rotor types e) PC-WFC: Wound-field commutator machines; all standard wound-field brushed rotor types f) PC-AXM: Axial flux machines; all stan- dard PM axial flux rotor types along with claw-pole and double radial PM flux machines
The radial or axial cross section of the machine is shown in the graphical Outline editor enabling interactive geometry modifications through the parameter list on the left side. Material databases are available in SPEED including steel, magnet and brush data.

Simcenter SPEED supports Simcenter Amesim™ software for system simulation by creating data files that can be exported from SPEED directly as: A simple linear parameter list or Flux linkage with iron loss 2D maps for the enhanced e-machine models within Simcenter Amesim
The Template editor collects all input parameters, whereas the Design sheet provides all the output data in numeri- cal format and the various Output graphs visualize the results in a graphi- cal manner, e.g. current, back EMF, torque or efficiency. Simcenter SPEED links to several gen- eral-purpose 2D and 3D electromagnetic finite element solvers such as Simcenter STAR-CCM+™, Simcenter MAGNET or to the Simcenter SPEED dedicated 2D magnetostatic program, PC-FEA. These enable modeling and study of the electric machine more precisely if needed, for example in cases of high saturation, under fault conditions, and non-SPEED template based geometries. In general, users can connect Simcenter SPEED with other tools required for the complete electric machine solution using various scripting or programming languages. More specifically, automa- tion makes use of the scripting capabili- ties as driving Simcenter SPEED on its own or together with other programs, such as STAR-CCM+. This automated workflow follows the scripting approach and uses STAR-CCM+ and its multiphys- ics solvers for electromagnetic, thermal (full 3D conjugate heat transfer) and mechanical stress analysis along with Java scripts to provide and feed back additional information to Simcenter SPEED. HEEDS is a powerful software package in the Simcenter portfolio that auto-mates the design space exploration process. Simcenter SPEED provides a built-in graphical user interface to access HEEDS in two ways: as a full HEEDS installation and as an integrated add-on tool. In both cases, Simcenter SPEED is linked to HEEDS via a Python script using the generic facilities within HEEDS.
