A system and a method are provided for detecting when a vehicle mounted battery pack is damaged due to an impact with a piece of road debris or other obstacle. The system utilizes a plurality of cooling conduits located between the lower surface of the batteries within the battery pack and the lower battery pack enclosure panel. The cooling conduits are configured to deform and absorb impact energy when an object strikes the lower battery pack enclosure panel. When the cooling conduits deform, a change in coolant flow/pressure occurs that is detectable by one or more sensors integrated into the conduit's coolant channels. A system controller, coupled to a sensor monitoring subsystem, may be configured to provide any of a variety of responses when cooling conduit deformation is detected.
