The invention relates to the technical field of battery power supply data measurement, in particular to a battery power supply safety supervision system suitable for a new energy automobile. The system obtains power supply data, and obtains an electrical correlation coefficient according to the change of the power supply data; correcting the power supply data according to the window of each size of the power supply data, and screening out a target window based on the difference of the power supply data before and after correction; and correcting the target window through the electrical correlation coefficient, obtaining an optimal window, obtaining de-noised power supply data through a local mean decomposition algorithm, and carrying out safety supervision. According to the method, the electrical correlation coefficient is obtained to correct the target window, and the optimal window is accurately obtained, so that the power supply data is efficiently denoised by the local mean decomposition algorithm, the fault information is reserved, and the battery power supply safety of the new energy automobile is ensured to be accurately supervised.
