One of the major challenges for electric vehicle safety and mobility is the development of battery protection mechanisms that are able to cope with irregular and unpredictable heating of the battery unit. Biological protection mechanisms are considered to be one of the most effective and resilient mechanisms due to their ability to react dynamically and adaptively to unpredictable disturbances. Consequently, biological systems can be viewed as models for high resiliency that provide inspiration for tackling issues such as excessive resource consumption or low technical resilience. This study demonstrates the improvement of the safety of an electric vehicle battery system inspired by wound healing and pain reflex response, which are among the most important protective mechanisms of the human body system. In particular, the individual mechanisms are systematically characterized, their underlying principles identified and transferred to a simulated battery system using a novel attribute-based method. As a result, the detection of irregular heating is improved and cooling of the battery system is more efficient. Further, this example can be used to explain how protective mechanisms that contribute to the resilience of biological systems can be abstracted and transferred to different technical systems.
