Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] Concrete steps of the present invention are as follows:

[0035] 1) First, assume that the pure electric bus runs on a fixed route and timetable, and each route runs several buses; each pure electric bus is equipped with the same power battery specification and capacity, and the pure electric bus runs from the depot every day The mileage from departure to return to the parking lot is less than the maximum mileage of the vehicle to ensure that the remaining power of the vehicle can be safely returned to the parking lot for charging, and it is only charged once a day during non-operating hours at night;

[0036] 2) Scheduling stage division of pure electric bus operation lines;

[0037] Such as figure 1 As shown, according to the service life of the pure electric bus, the minimum time unit of electric bus dispatching is defined as a stage, and the disp...

Abstract

The invention relates to a pure electric bus driving route planning method based on the reverse order matching of battery capacity degeneration and working load. The pure electric bus driving route planning method comprises that it is hypothesized that the driving routes and the timetables of pure electric buses are fixed, the specifications and the capacities of provided power batteries are the same, and the driving mileage of the pure electric bus from a yard starting place to returning to the yard starting place is less than the maximum driving mileage of the pure electric bus; the working loads of the batteries corresponding to all the driving routes are calculated; according to the initial states and the terminating states of the batteries at each stage, the total capacity degeneration change amounts of the batteries at each stage under different scheduling stats are sequentially calculated; and the route scheduling scheme of the pure electric buses is determined. According to the present invention, by comprehensively considering the driving characteristics of the pure electric bus, the power battery capacity degeneration characteristics, the working load characteristics and the mutual influence among the three conditions, through the reverse order matching of the bus sequences and the route sequences at each stage, the replacement number of the power batteries in the buses at each stage is minimized, and the complete utilization of the service life of the power battery within the service life of the whole bus is achieved.

Description

technical field [0001] The invention belongs to the field of process system engineering, and in particular relates to a pure electric bus operation route planning method based on battery capacity attenuation and reverse order matching of workload. Background technique [0002] As one of the important directions for the development of the automobile industry, new energy vehicles have gained wide recognition and attention, and have been gradually promoted in the transportation system. In particular, pure electric vehicles have gradually supplemented the public transportation system dominated by traditional fossil fuel vehicles. middle. Pure electric buses powered by lithium-ion batteries are one of the key development directions of new energy vehicles due to their outstanding advantages such as smooth driving, low noise, and no pollution, and have become an important part of urban public transportation systems. [0003] Pure electric vehicles use the electric energy stored in...
