The invention discloses a
lithium battery
thermal runaway sound source positioning error compensation method based on XGBoost, and the method comprises the steps: collecting sound signals, including time
delay and cross-power spectrum data, in an
energy storage cabin in a fixed
microphone array, and sound source positioning coordinates calculated by a conventional
geometric method, and then comparing the geometric positioning coordinates with actual sound source position coordinates, thereby achieving the compensation of the
thermal runaway sound source positioning error of a
lithium battery. And calculating a positioning error, and constructing a
feature vector. And training an XGboost model by using the feature vectors. In practical application, time
delay, cross-power spectrum data and geometric positioning coordinates which are calculated in real time are input, traditional geometric sound source positioning coordinates are corrected through error values obtained through the prediction model, and therefore the more accurate sound source position is obtained. According to the method, an XGBoost error compensation model is introduced to correct errors generated by geometric positioning, so that the position of the
thermal runaway lithium battery is accurately positioned.
