A battery pack enclosure, a battery module, and a method are provided to detect damage to in a crash event. The battery pack enclosure may include a plurality of battery modules, wherein each battery modules includes a plurality of adjacent battery cells. The battery pack enclosure may also include a sensor and an electronic control unit electronically connected to the sensor, the electronic control unit configured to monitor the sensor to detect damage to the battery pack enclosure. The sensor may comprise a mesh of resistive wires, and the electronic control unit monitors the overall resistance of the mesh resistive wires. The overall resistance of the mesh resistive wires can be used to determine whether there is damage to the battery pack enclosure. If damage is detected, the damage can further be located, and an alert sent.
