本文旨在研究双源电动公交车的能量管理。根据双源电动公交车的电力需求和储能系统的特点，提出一种基于小波变换的规则控制策略，在能源单元之间分配能量流，以获得高效的能量传递。利用小波变换理论对高低频分量功率需求进行分解和重构。将高频分量功率分配给超级电容，低频分量功率分配给电池组或电网，可以明显减少功率快速变化和浪涌负载对电池组和电网的损害。通过动态规划求解的基准在真实工况和中国标准客车工况下评估了该方法的有效性。进行仿真实验，结果表明，实际工况下平均电耗为0.9335kWh/km，与基准仅相差8.25%。此外，在中国标准客车行驶工况下，实现了9.02%的差异。最后进行了硬件在环实验，结果表明所提出的策略是合理的。
This paper aims at studying the energy management of the dual-source electric bus. Based on the characteristics of the power demand and the energy storage system of the dual-source electric bus, a rule-based control strategy based on wavelet transform is proposed to allocate the energy flow among the energy units to obtain efficient energy transfer. The high and low frequency component power demand are decomposed and reconstructed by wavelet transform theory. The high frequency component power is assigned to the super capacitor, and the low frequency one is assigned to the battery pack or power grid, which can obviously reduce the damage, caused by the power rapid change and surge load, to the battery pack and power grid. The effectiveness of the proposed method is evaluated by the benchmark solved by dynamic programming under both a real driving cycle and the standard China bus driving cycle. Simulation experiments are carried out and the results show that the average power consumption is 0.9335 kWh/km, which has only a difference of 8.25% compared with the benchmark under a real driving cycle. In addition, a 9.02% difference is realized under the standard China bus driving cycle. Finally, the hardware-in-loop experiment is performed and the results show that the proposed strategy is reasonable.
