@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.

Devices and interconnected systems are finding a foothold not only in our homes but in mainstream organizations. Here are three tips to mitigate the risk.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
