Method and device for estimating residual life of vehicle-mounted battery pack and storage medium

The invention discloses a method and device for estimating the residual life of a vehicle-mounted battery pack and a storage medium, and the method comprises the steps: obtaining the state parameters of the whole life cycle of a single battery cell in a battery pack through a BMS (Battery Management System) of the vehicle-mounted battery pack, taking the state parameters as first data, and selecting a plurality of battery cells as observation battery cells; determining initial m-time and staged m-time charge-discharge cycle data of the plurality of observation battery cells as second data based on the first data; processing the second data to obtain a three-dimensional data table; training a pre-established estimation neural network model by using the plurality of three-dimensional data tables until convergence; and obtaining a three-dimensional data table correspondingly generated by initial m times of charge-discharge cycle data and latest m times of charge-discharge cycle data of a plurality of observation
