Method for early detection of impending overheating of at least one battery cell of a battery, detection device and motor vehicle

摘要

The invention relates to a method for detecting impending overheating of at least one battery cell (14) of a battery (10), preferably for a motor vehicle, the impending overheating being detected as a function of at least one determined first variable relating to the at least one battery cell (14) . A temporal temperature gradient ((ΔT / Δt) i) of a temperature (Ti) recorded in a predetermined proximity to the at least one battery cell (14) and / or a voltage (Ui) of the at least one battery cell (14) is used as the at least one first variable ) determined.
