Non-destructive battery pack inspection and imaging

A system for non-destructive inspection of a battery pack based on vibration analysis, comprising:

• a mechanical excitation probe in contact with an exterior facing surface of an electric vehicle (EV), wherein the mechanical excitation probe vibrates the exterior facing surface, wherein an excitation signal corresponding to the vibrating travels through a battery pack of the EV;
• a gantry coupled with the mechanical excitation probe, wherein positioning of the mechanical excitation probe is adjusted using the gantry;
• a first differential sensor probe in contact with the EV at a predetermined distance from the mechanical excitation probe;
• and
• a processor configured to:
• receive first excitation data associated with a measurement of the excitation signal after the excitation signal passes through the battery pack from the first differential sensor probe, and
• receive an indication, based on the first excitation data, of a performance-related property of the battery pack.

A device for non-destructively inspecting a battery pack based on vibration analysis, comprising:

• a mechanical excitation probe;
• a gantry coupled with the mechanical excitation probe;
• a first differential sensor probe;
• a rover, wherein the gantry is mounted to the rover, wherein the rover is used to adjust positioning of the mechanical excitation probe by a larger magnitude than an adjustment made using the gantry alone;
• and
• a processor configured to:
• receive first excitation data associated with a battery pack of an EV from the first differential sensor probe, and
• receive an indication, based on the first excitation data, of a performance-related property of the battery pack.
