The invention relates to a method for optimizing energy management of an electric propulsion system of a vehicle, where the electric propulsion system of the vehicle comprises an energy storage system and an electric machine. The electric propulsion system also includes at least one power component, where the power component has an idle state and an operational state. The method comprises the steps of: a) determining at least one parameter of the electrical component in an operating state; b) inputting the parameters into a thermal model of the power component; c) predicting, in real time, the temperature Tp of an electrical component in an operating state on the vehicle; d) comparing the predicted temperature value Tp with a predetermined threshold value Tmax, and e) automatically reducing the magnitude of the current through the power component to a safety level if the predicted temperature value Tp exceeds the predetermined threshold value Tmax.

    本发明涉及一种用于优化车辆的电力推进系统的能量管理的方法,其中,车辆的电力推进系统包括能量储存系统和电机。电力推进系统还包括至少一个电力部件,其中,电力部件具有空闲状态和操作状态。该方法包括以下步骤:a)确定处于操作状态的电力部件的至少一个参数;b)将参数输入电力部件的热模型中;c)实时预测车辆上处于操作状态的电力部件的温度Tp;d)将预测温度值Tp与预定阈值Tmax进行比较,以及e)如果预测温度值Tp超过预定阈值Tmax,则自动将通过电力部件的电流的大小降低到安全水平。
