| description | The invention relates to the technical field of battery state-of-health prediction, and provides a vehicle-mounted battery state-of-health prediction method, which comprises the following steps: acquiring vehicle travel frequency, if the frequency is high, calculating the maximum discharge capacity of a battery in a corresponding discharge process according to discharge process data with high discharge depth, and if the frequency is low, calculating the maximum discharge capacity of the battery in a corresponding discharge process. Calculating the maximum discharge capacity of the corresponding discharge process of the battery according to the data of the charge process adjacent to the discharge process with low discharge depth and high charge amplitude, and obtaining an input sequence according to the data of the discharge process with high discharge depth and/or the data of the discharge process with low discharge depth and high charge amplitude, obtaining an output sequence according to the maximum dischar |
