The protective device is configured to conduct an electric current, which flows through the at least one battery cell, through a measurement element, in which the current generates an electrical measurement voltage in dependence on its amperage and/or its amperage gradient. The measurement element is coupled to an analog monitoring circuit, in which a comparison unit is configured to trigger a triggering signal for the case that the amperage rises at least by a predetermined delta value within a predetermined duration, and a switching unit is configured to receive the triggering signal and to interrupt the current upon receiving the triggering signal by switching at least one switching element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protective device and method for shutting down at least one battery cell in a battery system in case of an electrical short circuit, and also motor vehicle, battery system, and battery cell having the protective device","description":"A protective device for shutting down at least one battery cell in a battery system of a motor vehicle in case of an electrical short circuit.
