The invention provides an electric vehicle energy consumption prediction method and system based on road information and air conditioner heat management. Comprising the steps that S1, parameters of the electric vehicle are obtained; s2, total electric drive energy consumption is calculated based on the obtained parameters; s3, calculating energy consumption of a compressor based on the obtained parameters, and calculating total energy consumption of the thermal management system; and S4, based on the acquired parameters, the calculated total electric drive energy consumption and the calculated total energy consumption of the thermal management system, predicting the total energy consumption required for arriving at the destination, and recommending an energy-saving scheme to the user. According to the method, the actual energy consumption of the compressor is estimated by adopting the COP of the refrigeration (heat) energy efficiency ratio of the air conditioning system instead of simulation calculation of a thermal management model, so that the energy consumption of the thermal management system of the vehicle-mounted air conditioner is accurately estimated only by utilizing sensor parameters.

    本发明提供了一种基于道路信息及空调热管理的电动车能耗预测方法及系统。包括:步骤S1:获取电动汽车的参数;步骤S2:基于获取参数计算总电驱能量消耗;步骤S3:基于获取参数计算压缩机能量消耗,计算热管理系统总能耗;步骤S4:基于获取参数,以及计算的总电驱能量消耗以及热管理系统总能耗,预测出到达目的地所需的总能量消耗,将节能方案推荐用户。本发明通过采用空调系统制冷(热)能效比COP来估算压缩机实际能量消耗,代替热管理模型仿真计算,从而实现仅利用传感器参数较精准估算车载空调热管理系统的能量消耗。
