<正>一、典型插电式混合动力汽车高压部件1.典型插电式混合动力汽车架构插电式混合动力电动汽车(PHEV)使用电池为电机提供动力,使用另一种燃料(如汽油)为内燃机(ICE)提供动力。PHEV电池可以通过壁装插座或充电桩设备、ICE或再生制动进行充电。车辆通常依靠电力运行,直到电池几乎耗尽,然后汽车自动切换到使用ICE。本文以2018款路虎揽胜运动型P400e为例,来介绍典型PHEV,2015-2023年间生产的很多车型,都采用了这一架构。初期生产的车辆目前已到了社会维修期, 相似文献

Design of an energy management strategy for parallel hybrid electric vehicles using a logic threshold and instantaneous optimization method 总被引:2,自引:0,他引:2
Y.- J. Huang C.- L. Yin J.- W. Zhang 《International Journal of Automotive Technology》2009,10(4):513-521
A novel parallel hybrid electric vehicle (PHEV) configuration consisting of an extra one-way clutch and an automatic mechanical
transmission (AMT) is taken as the study subject of this paper. An energy management strategy (EMS) combining a logic threshold
approach and an instantaneous optimization algorithm is developed for the investigated PHEV. The objective of this EMS is
to achieve acceptable vehicle performance and drivability requirements while simultaneously maximizing engine fuel economy
and maintaining the battery state of charge (SOC) in its rational operation range at all times. Under the MATLAB/Simulink
environment, a computer simulation model of the studied PHEV is established using the bench test results. Simulation results
for the behavior of the engine, motor, and battery illustrate the potential of the proposed control strategy in terms of fuel
economy and in keeping the deviations of SOC at a low level. 相似文献

Recently Plug-in hybrid electric vehicles (PHEVs) have gained increasing attention due to their ability to reduce the fuel consumption and emissions. In this paper a new efficient power management strategy is proposed for a series PHEV. According to the battery state of charge (SOC) and vehicle power requirement, a new rule-based optimal power controller with four different operating modes is designed to improve the fuel economy of the vehicle. Furthermore, the teaching-learning based optimization (TLBO) method is employed to find the optimal engine power and battery power under the specified driving cycle while the fuel consumption is considered as the fitness function. In order to demonstrate the effectiveness of the proposed method, four different driving cycles with various numbers of driving distances for each driving cycle are selected for the simulation study. The performance of the proposed optimal power management strategy is compared with the rule-based power management method. The results verify that the proposed power management method could significantly improve the fuel economy of the series PHEV for different driving conditions. 相似文献

Series-parallel PHEV city buses combine the advantages of series and parallel configurations and have been used in China. However, the design and energy management of series-parallel PHEV city buses based on Chinese driving conditions still need to be investigated. In this paper, an equivalent consumption minimization strategy is provided to optimize energy management for series-parallel PHEV city buses, and the process of the equivalent consumption minimization strategy for series-parallel is presented in this paper. Compared with the validated rule-based energy control strategy, ECMS shows a fuel economy improvement of 8.2 % in the CBCD (Chinese Bus Driving Cycle). Based on the optimal energy management, a design for a generator motor in the series-parallel configuration has been processed. The fuel consumption has been shown to decrease, with an increase in generator power, because the system with the higher generator power can work at a higher efficiency in the series mode and operate the engine in the high efficiency area in the parallel mode. Besides, in terms of costof- ownership for a PHEV bus for lifetime of 8 years, although the high generator power will lead to high purchase cost for series-parallel PHEV bus, a series-parallel PHEV city bus with a generator of 100 kW maximum power will still show small advantage in cost-of-ownership, based on current motor price and natural gas price. 相似文献
