Abstract:

The objective of this research was to perform a teardown analysis on ten flood-damaged electric vehicles (EVs) recovered after Hurricane Ian in 2022. Nine of the vehicles retained a high state of charge, despite the water exposure and 10 months of storage. Upon inspection, infiltration pathways of saltwater into the battery packs were identified. The packs were assessed to determine the extent to which their designs and component degradation contributed to the ingress of water. For all vehicles, the volume of water infiltration was insufficient to trigger a thermal event. Nonetheless, the root causes of water infiltration into EV batteries due to saltwater damage were identified. The study provides valuable insights to guide future research on battery safety.
