Embodiment 1

[0109] see figure 1 , figure 1 It is a flow chart of a control method for fast charging applied to an on-vehicle system provided by an embodiment of the present invention. The method includes the following steps:

[0110] S11. The on-board system receives the ground allowable charging information sent by the ground charging station control system, and executes S12 after the on-board system receives the ground allowable charging information;

[0111] Among them, the on-board system and the ground charging station control system transmit information through microwaves. Specifically, both the vehicle and the ground charging station are equipped with wireless transmission devices, so as to realize the information transmission between the vehicle system and the ground charging station system. When the information sent by the other party cannot be received by each other, there is a failure in the transmission of confirmation information, so automatic charging control cannot be pe...

Embodiment 2

[0118] see figure 2 , figure 2 The charging flowchart in the fast charging control method applied to the vehicle system provided by the embodiment of the present invention. The method includes the following steps:

[0119] S21. Determine whether the vehicle has come to a stop and stopped; if it has come to a stop and stopped, then execute S22; if it has not come to a stop and stopped, then return to S21;

[0120] Among them, the basis for judging whether the vehicle stops at a stop is that the speed of the vehicle is equal to zero or the handbrake of the vehicle is applied, and the speed signal can be obtained through the vehicle speed sensor to determine whether the speed is equal to zero.

[0121] S22. The on-board system sends the information that the vehicle has stopped to the ground charging station control system, and receives the ground charging permission information sent by the ground charging station control system;

[0122] Optionally, after the in-vehicle syst...

Embodiment 3

[0139] see image 3 , image 3 The flow chart of charging and power-off in the fast charging control method applied to the vehicle system provided by the embodiment of the present invention. The method includes the following steps:

[0140] S31. The vehicle-mounted system receives the ground permission charging information sent by the ground charging station control system, and executes S32 after the vehicle-mounted system receives the ground permission charging information;

[0141] S32. Send a command to raise the bow, and control the receiver to rise;

[0142] S33. After the receiver is lifted in place, control the charging contactor of the vehicle to close, and send the vehicle charging permission information to the ground charging station control system;

[0143] S34. After the charging is completed, send the bow-down command to control the power receiver to drop; if the bow-down command is successfully sent to control the power receiver to drop, execute S35; if the bo...

Abstract

The invention provides a control method for quickly changing. The control method is applied to a vehicle-mounted system and comprises the following steps of receiving ground charging allowing information transmitted by a ground charging station control system, transmitting a pantograph ascending instruction and controlling a current collector to ascend; after the pantograph of the current collector ascends to be in place, controlling a charging contactor of a vehicle to be closed, and transmitting vehicle-mounted charging allowing information to the ground charging station control system; and after the charging is finished, transmitting a pantograph descending instruction, controlling the current collector to descend, and transmitting vehicle-mounted charging prohibiting information to the ground charging station control system. Likewise, the invention also provides a control method for quickly charging applied to the ground charging station control system, the vehicle-mounted system and the ground charging station control system. According to the control method, the vehicle-mounted system and the ground charging station control system provided by the invention, the problems that a heavy-current discharge arc is generated at the moment of charging or outage, so that a current collecting contact part is damaged, the service life of the current collecting contact part is shortened and potential safety hazards exist are solved.

Description

technical field [0001] The invention relates to the field of charging control for energy storage trolleybuses, and more specifically, relates to a fast charging control method, a vehicle-mounted system and a ground charging station control system. Background technique [0002] Trolley bus is known as "green bus". Its main advantages to buses are energy saving, environmental protection, comfort and sanitation, and its main advantages to rail transit are cheap and flexible. Trolleybus charging infrastructure is an important part of the tram industry chain. [0003] At present, trams can be charged quickly by tram platforms. When the energy storage trolleybus enters the station, the current is as high as more than 800 amperes, and the charging time is only a few tens of seconds after passengers get on and off the bus. After the vehicle leaves the charging area, the energy storage power supply of the vehicle releases energy, which can solve the problems caused by driving on ove...
