Problems solved by technology

[0007] Aiming at the shortcomings of conventional charging and charging time in the prior art that are too long and fast charging construction costs are large and restrictive, in order to solve the problem of electric vehicle power supply for long-term and long-distance driving, the present invention proposes a mid-way charging system for electric vehicles. Electric vehicles can be connected to the charging network at any time on the way, and continue to drive while charging, thus ensuring that electric vehicles can obtain electric energy supplements in a timely and convenient manner, reducing the construction cost of charging stations, and realizing the automatic access control technology. Intelligent authentication, billing and management of charging users fundamentally solve the problem of electric vehicles being popularized due to the difficulty of charging

[0024] see figure 1 The general schematic diagram of the present invention, the basic principle of the present invention is to erect a charging grid 10 in the air along the road, and the top of the electric vehicle 30 is equipped with a liftable pantograph 301 . The outer layer of the charging grid 10 above the road has an insulating protective shell 101. On the one hand, the insulating protective shell 101 plays a role of safety protection for the charging grid, and on the other hand, the insulating protective shell 101 also restricts the behavior of the electric vehicle 30 from connecting to the grid at will for charging. . There are base stations 20 at regular intervals within charging network 10 . If the remaining power of the on-board battery is insufficient, the electric vehicle 30 will drive to the nearby base station 20 and extend the pantograph 301. When the pantograph 301 and the base station 20 are close to each other to a predetermined distance, the near field com...

[0032] Figure 4 It is an overall schematic diagram of another specific embodiment of the present invention. As shown in the figure, the main difference of the electric vehicle intelligent midway charging system is that the charging grid 10 is laid on the road surface of the road, and the electric vehicle 30 is equipped with a Extend and retract the pantograph 301 . The insulating protective shell 101 on the outer layer of the charging grid 10 can also play a role of safety protection and limit the random access of the electric vehicle 30 to the grid. The base station 20 conducts near-field communication with the pantograph 301 close to a predetermined distance to obtain the identity information of the vehicle owner, and remotely transmits it to the management center 40 for authentication. The management center 40 performs user authority authentication through the authentication unit, and the command unit issues instructions after passing the authentication. , so as to comman...

Abstract

The invention provides a midway charging system for an electric vehicle. The electric vehicle is provided with a pantograph (301), a charging grid (10) is arranged along a road, and an insulating protection shell (101) is arranged on an outer layer of the charging grid (10); base stations (20) are arranged at certain intervals in the charging grid (10); when the pantograph (301) enters a preset range of one of the base stations (20), the base station (20) acquires the identification information of the electric vehicle (30) through near-field communication and remotely transmits the identification information to a management center (40), and the management center (40) authenticates the identification information; and under the condition that the identification information passes authentication, the management center (40) remotely controls the base station (20) to open the insulating protection shell (101) to allow the pantograph (301) to be contacted with the charging grid (10) for charging the electric vehicle, and the management center (40) performs billing and management. By adoption of the midway charging system for the electric vehicle, timely and convenient electric energy supplementation of the electric vehicle is ensured, the construction cost of a charging station is reduced, and the problem about charging of the electric vehicle in the prior art is fundamentally solved.

Description

technical field [0001] The present invention relates to electric drive automobile technology, and more specifically relates to an electric automobile midway charging system. Background technique [0002] An electric vehicle is a motor vehicle that relies on the on-board battery to provide energy and uses an electric motor to drive the wheels. Compared with traditional vehicles that use chemical fuels such as gasoline, electric vehicles achieve zero emissions of greenhouse gases such as carbon dioxide and pollutants such as sulfur and dust, significantly reducing the adverse impact of vehicles on the environment. Electric energy comes from a wide range of sources, such as water power, wind power, solar energy, nuclear energy, etc., which relieves the dependence of traditional automobiles on the increasingly depleted oil resources. According to calculations, the energy efficiency of electric vehicles is significantly higher than that of traditional gasoline-powered vehicles. ...
