The invention discloses a vehicle, a method and device for estimating the health state of a power battery of the vehicle and a storage medium, and the method comprises the steps: obtaining the health state, accumulated discharge change and accumulated standing time change of the power battery at the last moment, determining a first health state of the power battery at the current moment according to the health state of the previous moment, the accumulated discharge change and the accumulated standing time change, and obtaining the health states of the power battery in a discharge cycle and a charge cycle within a first preset mileage, and determining a second health state of the power battery at the current moment according to the health state of the discharging period and the health state of the charging period in the first preset mileage, and estimating the health state of the power battery according to the first health state and the second health state. According to the estimation method, the health state of the power battery is estimated according to the first health state and the second health state of the power battery at the current moment, the accuracy of an estimation result is improved, and safe application of the power battery in the whole life cycle is ensured.
本发明公开了一种车辆及其动力电池健康状态的估算方法、装置及存储介质,方法包括:获取动力电池上一时刻的健康状态、累计放电变化和累计静置时间变化,根据上一时刻的健康状态、累计放电变化和累计静置时间变化确定动力电池当前时刻的第一健康状态,获取动力电池在第一预设里程内放电周期和充电周期的健康状态,根据第一预设里程内放电周期的健康状态和充电周期的健康状态确定动力电池当前时刻的第二健康状态,根据第一健康状态和第二健康状态对动力电池健康状态进行估算。本发明的估算方法,根据动力电池当前时刻的第一健康状态和第二健康状态对动力电池健康状态进行估算,提高估算结果的准确性,确保动力电池全生命周期的安全应用。
