The invention provides a power inductor control method and device, electronic equipment and a storage medium, and relates to the technical field of boost charging. Comprising the steps of obtaining the current temperature of cooling liquid of the power inductor; determining a current allowable value corresponding to the current temperature based on a mapping relation between the cooling liquid temperature and a power inductance current allowable value; and controlling the current value passing through the power inductor to be lower than or equal to the current allowable value. Therefore, the current allowable value of the power inductor can be determined only by using the temperature of the cooling liquid without measuring the temperature of the power inductor, so that the current of the power inductor is controlled, the effective temperature protection of the power inductor is realized, and the cost of using a temperature sensor such as a thermistor is reduced; and the through-current capability of the power inductor can be better exerted.

    本公开提出一种功率电感的控制方法、装置、电子设备及存储介质,涉及升压充电技术领域。包括:获取功率电感的冷却液当前的温度;基于冷却液温度和功率电感电流允许值的映射关系,确定与所述当前的温度对应的电流允许值;控制通过所述功率电感的电流值低于或等于所述电流允许值。由此,可以不用测量功率电感的温度,仅需用冷却液的温度即可确定功率电感的电流允许值,以对功率电感的电流进行控制,实现对功率电感的有效温度保护,降低了使用热敏电阻等温度传感器的成本,并且可以更好的发挥功率电感的通流能力。
