The embodiment of the invention provides an endurance evaluation method and system for a new energy vehicle, and belongs to the technical field of new energy vehicle battery management. The method comprises the following steps: acquiring temporary working characteristic parameters of a power battery pack; determining the inconsistency of the power battery pack based on the temporary working characteristic parameters; determining a health value of the power battery pack based on the inconsistency of the power battery pack; driving habit parameters, stored in a preset driving time range, of the new energy vehicle are obtained, wherein the start-stop driving habit parameter is configured to reflect the acceleration or deceleration driving habit of the user; and determining the endurance kilometer of the new energy vehicle based on the health value and the driving habit parameter. According to the endurance evaluation method and system for the new energy vehicle, endurance evaluation of the new energy vehicle can be more accurately realized, and the influence of different users and different vehicles on endurance is avoided.
