The invention relates to the technical field of new energy, in particular to a working condition adjustment method and device of a power battery, a readable storage medium and a vehicle, and aims to solve the problems of how to perform working condition optimization on the power battery in a more targeted manner so as to effectively delay aging of the power battery and prolong the service life of the power battery. In order to achieve the purpose, the power battery meeting the working condition adjusting condition is determined according to historical state data of the power battery, relaxation time distribution of the power battery is further obtained, the dominant failure mode of the power battery is determined according to the relaxation time distribution, and the matched use working condition of the power battery is determined according to the dominant failure mode. Therefore, the working condition of the power battery is adjusted according to the matched use working condition, targeted working condition adjustment of the power battery in different attenuation states can be realized, so that the problem of aging of the power battery is delayed more effectively, the service life of the power battery is prolonged effectively, and the use experience of a user is improved.

    本发明涉及新能源技术领域,具体提供一种动力电池的工况调整方法、装置、可读存储介质及车辆,旨在解决如何更为有针对性的对动力电池进行工况优化,以有效延缓动力电池衰老,延长动力电池的使用寿命的问题。为此目的,本发明根据动力电池的历史状态数据确定满足工况调整条件的动力电池,进一步获取动力电池的弛豫时间分布,根据弛豫时间分布确定动力电池的主导失效模式,并根据主导失效模式来确定动力电池的匹配使用工况,从而实现根据匹配使用工况对动力电池的工况进行调整,能够实现对不同的衰减状态的动力电池有针对性的工况调整,从而更为有效地延缓动力电池衰老的问题,有效提升动力电池的使用寿命,进而提升用户的使用体验。
