PACCAR

State of Health Analysis for LFP Battery Second Life

BEV batteries still have some usable life once they are at vehicle end of life. These electric batteries see battery degradation typically due to exposure to high temperature, rapid charge and discharge cycles, and repeated utilization of maximum storage potential of the battery over time. This student team sought to understand the battery degradation over time along with the historical performance behavior of the battery, as this would help PACCAR to understand the battery second life repurposes. This student team attempted to analyze battery State of Health (SOH) through the vehicle life cycle and propose its future for its 2nd life once the batteries are at end of life for the vehicle use. The outcome this student team worked towards was an analysis report to complete a SOH analysis on the battery at the end-of-vehicle life stage through end-of-life stage.
