摘要
针对纯电动汽车动力电池能量密度低、续驶里程短的问题,基于BFC6110EV-2电动公交车,设计了增程式电动公交车的动力系统参数,并根据汽车设计方法对所匹配参数进行了理论校核。在AMESim软件中利用稳态试验数据建立了增程式电动公交车整车仿真模型,采用单点恒温器控制策略,利用联合仿真方法对所设计的动力系统进行了仿真验证。结果表明,该增程式电动公交车动力系统的设计与参数匹配较合理,与传统纯电动公交车相比,其动力性及续驶里程都具有一定的优越性。
To solve the problem of low capacity density of the battery pack and short driving range of battery electric vehicles, the powertrain and control strategy of a range-extended electric bus were designed based on the electric bus BFC6110EV -2. The parameters of the powertrain were verified according to vehicle design method. The bus simulation model was built with steady state database of Software AMESim. Single-point thermostat control strategy was implemented and the co-simulation method was adopted to verify the powertrain, The results show that the powertrain design and parameter matching are reasonable, they also show advantages in dynamic performance and driving range as compared with traditional battery electric bus.
