@richnass, We verify the model with special equipment that compares cell measurements under random charge discharge loads, against model predictions. We demonstrated the equipment last year at the battery show.

A very capable tool.

The other advantage to a tool like this is the ability not only to evaluate a battery pack on a specific vehicle, but also to evaluate a number of different hybrid arcthitectures. This can provide insight into the 'vehicle' aspect of the design as well.

@EllenGooch: That all sounds good in theory, but do you have actual data to back it up?

This development is very interesting, in that it accounts for such a high level of
complexity in the battery structure, allowing the simulation to much more
closely approach real-world conditions. It seems likely the battery simulation
will be extremely beneficial for any large cell-count application.

Thanks for the comment, Naperlou.  In re shortening analysis time, for a battery pack consisting of 100 series connected individual cells, simulation output is produced 20 times faster than simulated time. This even though each cell in a  pack is modeled individually to refelct statistical variations (as are thermal interactions between cells).

Chuck, this is an important step.  This is especially true for battery technology since, as you point out, there is no time to do life testing with real hardware.  The field is moving so fast that these tools are essential.  In the world of automotive where the production runs are large (although not yet for EVs) shortening the analysis time is a great asset.
