The invention particularly relates to a battery life prediction method for an electric vehicle. The method comprises the following steps: acquiring charging process data of a battery; inputting the charging process data into a curve prediction model constructed based on a generative adversarial network to obtain a predicted charging voltage curve image; extracting corresponding charging voltage characteristic data from the predicted charging voltage curve image; inputting the extracted charging voltage characteristic data into a life prediction model constructed based on a deep learning model to obtain a battery life value; and taking the predicted battery life value output by the life prediction model as a battery life prediction result of the electric vehicle, and feeding back the result to a user of the electric vehicle, so that the user knows the battery state of the electric vehicle. According to the method, the high-quality charging voltage characteristic data is efficiently and accurately extracted through the generative adversarial network, the service life of the battery is comprehensively, accurately and efficiently predicted through the deep learning model, and a user is assisted to effectively pre-judge charging, maintenance and replacement of the battery.
