Ebike Battery Pack Design Tools

The means to model batteries.

Now includes pouch cell design!

The tried and true method for designing batteries. The Battery Design Studio^® software is based on years of testing and used by battery developers around the world.

Battery Design Studio^® is an essential tool for battery professionals. This user-friendly software environment contains everything you need for analyzing battery data, design, and simulation of batteries (cells and packs).

Use the software to design experiments, analyze experimental data, maintain a database of components and cell designs, carry out simulations, fit model parameters, and generate reports.

Experimentalists use Battery Design Studio^® for data analysis and visualization. The Outviewer program works with data from many commercial battery cyclers to visualize and analyze test data.

The software provides a powerful means to exchange information with colleagues in a consistent and complete manner.

The software now includes a gap analysis for hybrid electric vehicle (HEV) batteries. The software can analyze test data for HEV batteries to determine how well the batteries meet USABC goals.

Order Battery Design Studio^®(Lithium-ion version; ask about other chemistries). to start designing and modeling battery performance. A battery is an extremely complex physicochemical system that can really only be understood with the aid of mathematical models. Battery Design Studio^® provides users with easy access to these models.

Battery developers - don't reinvent the wheel. Use Battery Design Studio^® as the foundation of your proprietary battery design software. Battery Design Studio^® can be easily customized to your proprietary designs at a much lower cost than developing or supporting in-house software maintenance.

Besides lower cost, Battery Design Studio^® provides battery developers with more features.

Visualization tools allow you to rapidly analyze both experimental and simulation results.

Battery Design Studio^® provides a series of user-friendly interfaces that allow the battery design (spiral wound or stack cell) to be specified. The design information is automatically linked to a simulation model that can predict current/voltage/temperature behavior. Simulation model parameters are obtained by fitting to experimental data, and tools are provided to help accomplish this task.

Simulation models can reduce an entire database of experimental results to a single set of simulation parameters. These parameters can be encrypted and distributed so that others can use them to simulate battery performance without having access to the underlying design information. In this way, battery users can evaluate batteries under their specific use conditions without having to carry out expensive and time-consuming battery testing. The net result - battery developers can reduce the time required to qualify their products while providing more value to their customers.

Cell models can be used to estimate performance of packs. Different cells can be evaluated as well as different internal arrangements.

The standard version is specific for lithium-ion chemistries; other chemistries (Li/SOCl2, Zn/Air) can be provided on request. Lithium-ion simulation models for mixtures of active materials, and multi-layer coatings are available.

Battery Design Studio^® is designed with flexibility and modularity so it can be easily customized. Battery developers can realize significant cost savings by using Battery Design Studio^® as an in-house platform for battery design rather than develop a package from scratch. The maintenance cost of in-house software can be significantly reduced by using Battery Design Studio^®.

For experts in modeling, a software development kit is available that allows development of custom models. Start with one of the following models:

1) BDS_DUAL - lithium-ion simulator similar to Newman's DUALFOIL (Duhamel solution to solid-phase diffusion problem) but with more options.

2) BDS_DUAL2N - lithium-ion simulator that solves solid-phase diffusion problem for N different active materials in each electrode using Duhamel's method.

3) BDS_DIST - lithium-ion simulator that solves solid-phase diffusion problem numerically.

4) BDS_DISTNP - lithium-ion simulator that solves solid-phase diffusion problem numerically for N different active materials in each electrode.

5) BDS_Lump - lithium-ion simulator that solves solid-phase diffusion problem using lumped-parameter model.

6) BDS_Lump2D - lithium-ion simulator that solves solid-phase diffusion problem using lumped-parameter model including current profiles along length of electrodes.

7) BDS_FOIL - simulator for lithium metal anode with intercalation cathode.

8) BDS_SOCL2 - Lithium thionyl chloride simulator.

9) BDS_ZnAir - Primary Zinc Air simulator.

Suppliers to the battery industry can provide information on their materials and components for battery developers to access. Materials such as active materials, additives, electrolytes, and separators can be included as well as components such as cans, seals, PTCs, headers, and spacers. Battery developers will see these materials and components as options in building cells.

R&D people can use the software to (1) assess the impact of changes in materials properties on cell performance, and (2) demonstrate the benefits of improvements to interested parties. For example, the effect of an increase in cathode capacity on battery energy density can be instantly assessed.
