CrossChasm has been working with PSAT, a vehicle energy simulation tool, since 2004. PSAT is a leading vehicle simulation tool developed by the Argonne National Lab, which can estimate the energy and performance of a vehicle without building physical prototypes.

CrossChasm works with manufacturers in the light duty passenger vehicle market, the commercial vehicle market, and the heavy duty industrial vehicle market. Using PSAT, CrossChasm better enables vehicle manufacturers to:

• Develop an appropriate set of performance targets for each powertrain component
• Have high confidence that their final design will hit the desired performance targets
• Have high confidence in the vehicle’s overall business case
• Identify battery cycling profiles and replacement intervals
• Achieve higher vehicle efficiencies by optimizing component size and control strategies

and most importantly, to achieve the above:
• Faster and cheaper than can be done with full-scale physical prototyping

The accuracy of the models can typically produce energy consumption estimates of less than 5% deviation from real-world values for passenger vehicle electric vehicles, and down to 2-3% accuracy for conventional vehicles. CrossChasm’s typical simulation process involves collecting vehicle usage data from vehicles already in service, developing accurate vehicle models and simulating these together; in this way, we have virtual vehicles of known accuracy, combined with real-world driving data. This process strengthens your ability to deliver a vehicle that meets the true performance requirements of your customers, and allows you to evaluate powertrain alternatives and tradeoffs.
