The Value of Battery Diagnostics and Prognostics

Battery diagnostics and prognostics techniques are often being underused and their value undermined because of the lack of adequate communication tools to transfer the understanding between the material scientists, who understand the inner working of the battery, and the engineers, who need to ensure proper battery usage. Even with the complex postmortem analyses, it is often very difficult to correlate what happened during practical use with laboratory testing, especially in a quantitative manner with temporal resolution. Here we explain a simple yet practical diagnostic and prognostic technique that could transfer such knowledge quantitatively with temporal variations to enable battery diagnostics and prognostics for better BMS design.
