Analysis on control strategy of series hybrid bus

hybrid electric vehicle is a feasible solution to solve the problems of environmental pollution and energy at present. Based on advisor software, first determine the power hybrid form, and carry out parameter design and vehicle modeling for engine, motor and other components according to the requirements of its various performance. Using the power following control strategy, input the parameters in the advisor cover of the simulation software, and modify the relevant control strategy, and finally get the simulation results. The results show that compared with traditional internal combustion engine vehicles, series hybrid vehicles have great advantages in terms of power, fuel economy and emission performance. If the plastic industry wants to take advantage of the development of new materials industry, it can start from the following aspects: potential

the energy model of series hybrid electric vehicle is shown in Figure L, which represents the energy relationship of motor, engine and battery pack. The purpose of the control strategy is to rationalize this relationship and optimize fuel consumption and emissions on the basis of ensuring the requirements of vehicle power parts. At present, the control strategies of series hybrid electric vehicles can be divided into two types: power follower and thermostat (internationally speaking, thermostat)

the power following mode focuses on controlling the battery to be the best, controlling the battery to work in a very favorable area and charging and discharging the battery at all times, that is, making the battery always work in a shallow cycle near the set power range, so as to maintain the battery at a certain amount of state of charge (high SOC value). All these are very beneficial to the battery life. After comprehensive consideration, the power following control strategy is selected. The power following control strategy is analyzed below

hybrid electric vehicle is a feasible solution to solve the problems of environmental pollution and energy at present. Based on the fact that the shipment of power batteries reached 6.67gwh in the first half of this year, the advisor software first determined the power hybrid form, and carried out parameter design and vehicle modeling for engine, motor and other components based on the requirements of its various performance. Using the power following control strategy, input the parameters in the advisor cover of the simulation software, and modify the relevant control strategy, and finally get the simulation results. The results show that compared with many scientific research experiments of traditional internal combustion engine vehicles, series hybrid vehicles have greater advantages in power, fuel economy and emission performance
