Integrated operation network intelligent control system for electric vehicles

Abstract

The invention relates to the field of electric vehicles, in particular to an integrated operation network intelligent control system for electric vehicles. The integrated operation network intelligent control system for electric vehicles comprises a vehicle body plate, a chassis, seat boxes, a power system and an operating system, and is characterized in that the operating system comprises an energy subsystem and an auxiliary system. The energy management system is respectively connected with a power battery, a charger and an electronic control unit to allow for real-time monitoring of the power battery. The power battery is connected with a power converter to allow for power outputting. The vehicle body plate is in a closed structure. Three to eight glass-window doors are arranged on each side of a vehicle body and as many as the rows of seat boxes. Compared with the prior art, the integrated operation network intelligent control system for electric vehicles has the advantages that the requirements of passengers for fast boarding and alighting and safety escape are met; information transmission through network is allowed by means of a network intelligent data acquisition module which is highly universal and fully functional; Modbus field bus protocol is adopted; and the system with the 100Ah lithium iron phosphate battery pack is long in service life and pollution-free.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an integrated operation network intelligent control system for electric vehicles. Background technique [0002] With the increasing pace of urban life and the further enhancement of people's awareness of environmental protection, people have put forward higher requirements for transportation tools. From the perspective of solving environmental pollution and coping with energy shortages, electric vehicles will have the potential to replace traditional fuel vehicles. possibility. The types of electric vehicles include fuel cell electric vehicles, hybrid vehicles and pure electric vehicles. [0003] Pure electric vehicles are divided into two categories: motor vehicles and field vehicles. At present, field electric vehicles are mostly simple sightseeing vehicles (or flat vehicles). With the increasing market demand for field electric vehicles, large-scale enterprise factories Comm...

Problems solved by technology

The open structure of electric vehicles is quite different from that of box-type vehicles. The disadvantage is that there is no air-conditioning in summer and no heating in winter in the north, and polluting lead-acid batteries are often used for power supply; in terms of vehicle control, simple speed regulation is often used. way, driving safety cannot be guaranteed, and due to the lack of network digital detection and field bus protocol, the control of field electric vehicles cannot realize network intelligence

In field electric vehicles, the currently used CAN bus needs to use a twisted-pair shielded bus cable with an impedance of 120Ω, which is a multi-master competitive bus structure, and the hardware cost is high.

[0004] In addition, in terms of battery configuration for field electric vehicles, there is a lack of low-cost, long-life energy storage battery configurations, and in terms of car body structure, it does not have a double-sided multi-door structure to meet the conditions for multiple people to get on and off at the same time and escape safely
