Embodiment Construction

[0017] 1. Charging system for double pantograph electric vehicles during driving

[0018] The charging system of the double pantograph type electric vehicle in the present invention is shown in figure 1 and figure 2 , which consists of an external power supply part and a vehicle-mounted power receiving part. Among them, the power supply part outside the vehicle consists of two rail-type transmission lines (3) and return lines (4) laid on the charging lane, and an insulating tape between the transmission lines (3) and return lines (4) and the ground. (6) Composition. The distance between the transmission line and the return line can be 30cm. They can be arranged on the main road of the city, the slow lane of the expressway or the special charging lane. The transmission line (3) is equivalent to the live line in the two-phase AC to supply power. The return line (4) is equivalent to the zero line and plays the role of return flow. Both the transmission line and the return li...

Abstract

The invention discloses a charging system in the driving state of electric cars, which comprises an external power supply part and a vehicle power-receiving part, wherein the external power supply part consists of rail-style transmission lines and reflow lines which are laid on a charging driveway and insulation tapes between the reflow lines and the ground; the vehicle power-receiving part consists of a pantograph assembled on the car body, a pantograph slide plate, transmission lines and a pantograph lifting control system thereof. When the electric car requires to be charged and drives to the charging driveway, the pantograph is put down under the control of the pantograph lifting control system; the contact surfaces of the slide plate transmission lines on the pantograph slide plate are in electric contact with the contact lines in sliding for receiving the current and charging when a car drives. The charging system charges the running electrical cars and solves the disadvantages that the battery capacity of the electric cars cannot support long-time sustained running.

Description

technical field [0001] The invention relates to a charging system for charging an electric vehicle during running, and belongs to the technical field of electric vehicles. Background technique [0002] With the development of urbanization and the continuous improvement of residents' living standards, more and more families have private cars, urban road traffic problems and urban air pollution problems are also increasing, and with the depletion of oil resources, new energy Technology to replace the existing petrochemical energy has become an urgent problem in today's world. [0003] Vigorously promoting electric vehicles in the urban transportation system has become an effective way for governments of various countries to solve problems such as oil resource shortage, exhaust emissions, and vehicle noise. The enthusiasm for buying electric vehicles is not very high. What is certain is that electric vehicles are cheaper to use than traditional vehicles. Ordinary battery vehi...
