The invention discloses a power battery health degree estimation method and a vehicle. The method comprises the following steps: acquiring battery data of a power battery; the first health degree and the second health degree of the power battery are determined on the basis of the battery data, the first health degree is the health degree of the power battery in the standing mode, the second health degree is the comprehensive health degree of the power battery in multiple working modes, and the multiple working modes comprise the vehicle working mode and the battery replacing station working mode; and estimating the target health degree according to the first health degree and the second health degree. The technical problems of poor reliability and low accuracy of an estimation result caused by estimating the health degree of the battery based on a single battery use mode in the prior art are solved.

    本发明公开了一种动力电池健康度的估算方法及车辆。其中,该方法包括:获取动力电池的电池数据;基于电池数据确定动力电池的第一健康度和第二健康度,其中,第一健康度为动力电池在静置模式下的健康度,第二健康度为动力电池在多种工作模式下的综合健康度,多种工作模式包括车辆工作模式和换电站工作模式;根据第一健康度和第二健康度估算目标健康度。本发明解决了相关技术基于单一电池使用模式估算电池健康度导致估算结果的可靠性差、准确度低的技术问题。
