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.

    本发明实施例提供一种新能源汽车的续航评估方法、系统,属于新能源汽车电池的管理的技术领域。包括:获取所述动力电池组的临时工作特征参数;基于所述临时工作特征参数确定所述动力电池组的不一致性;基于所述动力电池组的不一致性确定所述动力电池组的健康值;获取所述新能源汽车已存储的预设行驶时间范围内的驾驶习惯参数;其中,所述启停行驶习惯参数被配置为反映用户的加速或减速的驾驶习惯;以及基于所述健康值与所述驾驶习惯参数确定所述新能源汽车的续航公里。该新能源汽车的续航评估方法、系统可以更准确的实现新能源汽车的续航评估,避免不同用户不同车辆对于续航的影响。
