The invention relates to a method and a system for estimating the current energy consumption of an electric vehicle, where the electric vehicle (1) is powered by a propulsion battery (2), the method comprising: obtaining (S102) previous energy consumption values (ECt-1, ECt-2, ECt-3) and current driving mode parameter values at a set of previous moments (t-1, t-2, t-3); a current energy consumption (ECt) is estimated (S104) based on a weighted moving average model (5) fed with energy consumption values, where the weighted moving average model contains a modeling gain factor for each of at least a portion of previous energy consumption values, where the modeling gain factors are modeled as a function of the driving mode parameter.

    本发明涉及用于估计电动车辆的当前能耗的方法和系统,其中该电动车辆(1)由推进电池(2)供电,该方法包括:获得(S102)一组先前时刻(t‑1、t‑2、t‑3)的先前能耗值(ECt‑1、ECt‑2、ECt‑3)和当前驾驶模式参数值;基于馈送有能耗值的加权移动平均模型(5)来估计(S104)当前能耗(ECt),其中,加权移动平均模型包含先前能耗值中的至少一部分中的每一个的建模增益因子,其中建模增益因子被建模为驾驶模式参数的函数。
