Predicting Battery Capacity Fade Quickly and Accurately

As battery-driven electric vehicles come into the mainstream, predicting battery longevity becomes critical for various reasons. The battery pack is typically the single most expensive component of an EV, currently ranging anywhere between 30% to 40% of the total cost. In order to instil customer confidence, it is imperative that manufacturers provide lengthy warranties for […]

What is HPPC testing and why is it important for battery modelling?

The Hybrid Pulse Power Characterization (HPPC) test was first proposed by the US DOE as a standardized test to determine the dynamic power capability over the cell’s useable charge and voltage range1. The primary objective of the test is to establish, as a function of the depth of discharge (DoD) the Vmin discharge power capability […]

How accurate are our results?

The proof of the pudding: How accurate are our results? When we created the back-end code for the thermal management app, we worked to solve for multiple mathematical and physical models. It was a complex process since it involved operations at both the cell and module levels. While we had faith in our approach, the […]
