Electrical vehicle ground power supply device, method, controller and storage medium

Abstract

The invention discloses an electrical vehicle ground power supply device, a method, a controller and a storage medium. Adjacent power supply rail GDGs are mutually insulated and connected to form a power supply rail line, a power switch circuit DYKG is connected between a power supply positive electrode and the power supply rail GDGs, a safety grounding switch circuit AQDJ is connected between thepower supply rail GDGs and the negative electrode of the power supply, a controller CONTRL receives a vehicle close signal PSR, the power supply rail voltages and the current signals UO and IO, and controls on-off of the power supply switch circuit DYKG and the safe grounding switch circuit AQJD. No-vehicle electricity-free, and vehicle and electricity are realized, and the power supply rails arefully covered by the vehicle. When the vehicle leaves, the power switch circuit is turned off, the safety grounding switch circuit enters the on state, and the power supply rails are in a safe grounding state; and when the power switch circuit is in the burning loss short circuit state, the safety grounding switch circuit is used for grounding the power supply rails, a fuse FU is disconnected, and the power supply device is safely removed from the power grid.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power supply, in particular to an electric vehicle ground power supply device, method, controller and storage medium. Background technique [0002] Ground power supply technology for electric vehicles is beginning to be favored by city builders due to its many advantages such as canceling overhead network cables, convenient and safe approach, and favorable urban landscape. In the prior art, one way of this ground power supply technology is to use a contact switch circuit module to continuously supply power to vehicles in sections. When the vehicle is approaching, with the help of the magnetic pickup device on the vehicle, the conductor element of the module is disconnected from the ground potential, and the positive feeder is connected to the conductor element of the module; when the vehicle is far away, the magnetic force on the vehicle is lost By the action of the pick-up device, the f...

AI Technical Summary

Problems solved by technology

[0003] 1) There are many faults and short circuits often occur;

[0004] 2) The power supply module is directly connected to the power supply system, and the fault diagnosis in the system does not have the function of isolating the fault of the power supply module

[0005] 3) When the module fails, there will be positive contact adhesion, which will make the module positively charged and endanger personal safety

However, if the diverter switch breaks down, the corresponding road power supply assembly will be in a state of being charged all the time, causing potential safety hazards, and cannot be eliminated in time.

In addition, the cable connection mode between the road power supply assemblies is also prone to open circuit faults, which affect the power supply of the whole line
