The invention discloses a power battery, a vehicle and a power battery thermal management method, and relates to the technical field of batteries. The power battery comprises a box body, a battery cell and a circulating pipeline, the box body is provided with an accommodating cavity, the battery cell is accommodated in the accommodating cavity, the accommodating cavity is used for filling a heat exchange medium to immerse the battery cell, and two ends of the circulating pipeline are respectively communicated with the accommodating cavity to form a flow channel for the heat exchange medium to circularly flow; a first heat exchanger is arranged on the circulating pipeline and is used for being connected into an air conditioning system of the vehicle, so that a refrigerant in the air conditioning system selectively exchanges heat with the heat exchange medium; and/or a second heat exchanger is arranged on the circulating pipeline, and the second heat exchanger is used for being connected into a water cooling system of the vehicle, so that cooling liquid in the water cooling system selectively exchanges heat with the heat exchange medium. According to the power battery and vehicle heat exchange system, the integration degree is higher, heat management with lower energy consumption can be carried out, and heat generated by the power battery can be recycled.

    本发明公开了一种动力电池、车辆及动力电池热管理方法,涉及电池技术领域。该动力电池包括箱体、电芯及循环管路,箱体具有容置腔,电芯容置于容置腔内,容置腔用于灌注换热介质以浸没电芯,循环管路的两端分别与容置腔连通,以形成供换热介质循环流动的流道;循环管路上设置有第一换热器,第一换热器用于接入车辆的空调系统,以使空调系统中的制冷剂选择性地与换热介质换热;和/或,循环管路上设置有第二换热器,第二换热器用于接入车辆的水冷系统,以使水冷系统中的冷却液选择性地与换热介质换热。本发明提供的动力电池与车辆换热系统的集成度更高,能够进行能耗更低的热管理,并能够将动力电池产生的热量进行再利用。
