The embodiment of the invention provides a battery cooling capacity diagnosis method and device, a storage medium and electronic equipment, and the method comprises the steps: executing the first-stage cooling capacity diagnosis of a battery cooling system when a vehicle and an environment where the vehicle is located meet a first preset condition; and after the first-stage cooling capacity diagnosis is executed, under the condition that the vehicle and the environment where the vehicle is located meet a second preset condition, second-stage cooling capacity diagnosis of the battery cooling system is executed. According to the embodiment of the invention, before the temperature of the battery reaches the cooling threshold, whether the two-stage cooling capacity is in a normal or limited state is identified, so that preventive measures are taken in advance, and the conditions that the temperature of the battery rises rapidly and the charging and discharging capacity is reduced rapidly due to the limited cooling capacity of the system when the battery really reaches the cooling threshold are prevented; in this way, the potential risk of the fault is reduced to the minimum, and the risk of power interruption in the driving process of the driver is avoided.

    本公开实施例提供一种电池冷却能力的诊断方法、装置、存储介质及电子设备,所述诊断方法包括:当车辆以及所在环境满足第一预设条件的情况下,执行电池冷却系统的第一级冷却能力诊断;在执行第一级冷却能力诊断后,当车辆以及所在环境满足第二预设条件的情况下,执行电池冷却系统的第二级冷却能力诊断。本公开实施例在电池温度还没达到冷却门限前识别上述两级冷却能力是否处理正常或者受限状态,从而提前做出预防措施,防止当电池真达到冷却门限时因系统冷却能力受限而造成电池温度迅速上升且充放电能力迅速降低的情况,这样,不仅将该故障的潜在风险降到最低,还避免了驾驶员行驶过程的动力中断的风险。
