Abstract
A method and apparatus for determining an arcing temperature. The method comprises: providing a first conductive portion and a second conductive portion with reference to a material that is capable of forming an arc in a power battery, during testing, connecting the first conductive portion and the second conductive portion to a circuit to form a test loop (S110), then separating the first conductive portion from the second conductive portion to form an arc (S120), and then analyzing spectral lines radiated by the arc to determine the arcing temperature (S130). By analyzing the spectral lines of spectra, a local thermodynamic equilibrium condition, for example, can be used to analyze the intensity of the spectral lines, to obtain the arcing temperature, so that the detection capability is higher, and detection is simpler and more accurate.
