Abstract

Due to the rugged driving conditions, the current of the mining dump truck changes violently during operation, and there is an instantaneous high current charge/discharge, which affects the feedback efficiency and battery life. Therefore, aiming at the demand of braking energy recovery of NTE150 hybrid electric mine truck, this paper studies the parameter matching problem of the mining truck with the power battery and supercapacitor as composite power supply. Firstly, the parameter matching method of the composite power supply according to rules is given. Then the composite power supply parameters are optimised using a multi-objective genetic algorithm with the mining truck's load capacity and the power battery loss as evaluation indexes. Secondly, compared with the rule-based configuration scheme, the optimised configuration scheme decreases the power battery loss by 5.28% and the total weight of the energy storage device by 30.92%.

以制动能量回收最大化为目标的矿用车辆复合电源参数匹配

矿用自卸车由于行驶条件恶劣，在运行过程中电流变化剧烈，存在瞬时大电流充放电现象，影响反馈效率和电池寿命。因此，本文针对NTE150混合动力矿用汽车制动能量回收的需求，研究了动力电池和超级电容器作为复合电源的矿用汽车的参数匹配问题。首先，给出了基于规则的复合电源参数匹配方法。然后以矿用卡车载重能力和动力电池损耗为评价指标，采用多目标遗传算法对复合电源参数进行优化。其次，与基于规则的配置方案相比，优化后的配置方案使动力电池损耗降低5.28%，储能装置总重量降低30.92%。
