Battery pack and module health status check following an impact event

A system for diagnosing a health of a battery unit of a vehicle, comprising:

• a vehicle dynamics sensor for measuring vehicle dynamics data for the vehicle during a time period in which an impact event occurs at the vehicle;
• an accelerometer for obtaining a battery unit acceleration data for the battery unit during the time period;
• a processor configured to:
• determine an inertial load on the battery unit from the vehicle dynamics data and the battery unit acceleration data;
• compare the inertial load to a threshold determined using a virtual model of the battery unit to determine a health status of the battery unit;
• and
• perform a remedial action for the battery unit based on the health status.

A vehicle, comprising:

• an accelerometer for obtaining a battery unit acceleration data for a battery module of the battery pack during the time period;
• a processor configured to:
• determine an inertial load on the battery module from the vehicle dynamics data and the battery unit acceleration data;
• compare the inertial load to a threshold determined using a virtual model of the battery pack to determine a health status of the battery pack;
• and
• perform a remedial action for the battery pack based on the health status.
