Measures of Energy Consumption Resolution and Reduction for Pure Electric Bus

对一款纯电动客车整车能量消耗率进行分解,分析各项能量消耗率的影响因素,发现整车轻量化和降低滚阻系数对该纯电动客车在中国典型城市工况能量消耗率的降低最有效。通过一系列降耗措施,增加续驶里程29 km,能量消耗率降低12.5%。

The author resolves the energy consumption rate for a pure electric bus, analyzes the influence factors of each energy consumption rate, and finds that reducing the vehicle weight and rolling resistance coefficient are the most effective ways to reduce the energy consumption rate of the pure electric bus under the China typical city cycle. By a series measures of reducing the energy consumption, the range of the electric bus increases 29 km and the en- ergy consumption rate reduces12.5%.
