The embodiments of the present invention will be described in conjunction with the drawings of the specification, it being understood that the preferred embodiments described herein are merely for purposes of illustration and explanation, and are not intended to limit the invention. And features in embodiments of the invention may be combined with each other without conflict.
Example one
The embodiment provides a platform type based electric vehicle line charging system, and a platform mode based on-line charging technology is formed by transplanting a charger and a pantograph from vehicle-mounted installation to ground platform installation, so that the charger and the pantograph are prevented from being limited by the whole vehicle environment, and the usability and reliability of the on-line charging system can be greatly improved.
Fig. 1 is a schematic view of the location distribution of the system. The battery pack for charging is installed on the electric vehicle, and the charger (not shown in fig. 1) and the pantograph are installed on the platform, so that the weight of the whole vehicle can be reduced, and the space on the vehicle can be saved. Therefore, each vehicle in the prior art is required to be provided with one set of charger and pantograph, the charging system is established at the first and last stations, and on average, each 10 trolleys are provided with one set of charger and pantograph, so that the cost of the whole charging system is greatly reduced.
Fig. 2 is a schematic diagram of the main circuit principle of the system. The charger of the platform part provides electric energy for the pantograph, and after a driver operates the vehicle to enable the pantograph to be matched with the position of the electrode plate of the vehicle-mounted part, the pantograph charges the battery pack of the vehicle-mounted part through the charging loop.
Fig. 3 is a schematic structural diagram of an online charging system for an electric vehicle according to this embodiment. The system mainly comprises platform equipment and vehicle-mounted equipment. The platform equipment is arranged on a platform and comprises a charger 311, a pantograph controller 312 and a pantograph 313, wherein the charger 311 is connected with the pantograph controller 312 through a CAN network. The in-vehicle device is provided on the body of the electric vehicle, and includes an electrode plate 321 and an in-vehicle controller 322.
Wherein pantograph 313 is mounted directly above the vehicle charging tunnel. Pantograph controller 312 establishes a wireless route with on-board controller 322. The vehicle controller 323 of the electric vehicle is connected with the vehicle controller 322 through the CAN network, and further exchanges charging data with the pantograph controller 312 through the wireless route, after determining that the charging condition is satisfied, the vehicle controller 323 controls the pantograph controller 312 to perform a pantograph lowering operation, so that the pantograph 313 contacts with the electrode plate 321 of the vehicle device, and the charger 311 charges the battery system 324 through the pantograph 313 and the electrode plate 321.
In addition, the vehicle controller 323 controls the pantograph controller 312 to perform the pantograph-raising operation after determining that the charging, the charging failure, or the exit from the charging state is completed and confirming that the power-off condition is satisfied, thereby completing the entire charging process.
The embodiment is also provided with an image monitoring device to realize image recognition and guide a driver to safely and accurately park and charge at the platform. As shown in fig. 3, the station apparatus further includes a camera 314 for acquiring a real-time image and a pantograph state image of the vehicle. The pantograph controller 312 retrieves a simulation image consistent with the vehicle type, and superimposes the simulation image with the vehicle real-time image and the pantograph state image to form a real-time monitoring image for displaying the relative position state of the pantograph and the electrode plate.
The in-vehicle apparatus further includes a display (not shown in fig. 3), and the in-vehicle controller 322 receives the real-time monitoring image through the wireless route and displays the real-time monitoring image on the display, wherein the vehicle controller 323 controls the pantograph controller 312 to perform a pantograph lowering operation after the pantograph is matched with the position of the electrode plate.
The system of the present embodiment implements management of the vehicle using ETC. In fig. 3, the platform device further includes the ETC identification device 315, and the in-vehicle device 320 further includes an ETC tag 325. When the electric vehicle enters the charging channel, the ETC identification device identifies the ETC tag of the vehicle, and the pantograph controller 312 confirms that the ETC tag is a legal tag, and then can establish a wireless connection with the on-vehicle controller 322.
In order to ensure safe parking of the vehicle, the vehicle controller 323 also controls the traveling speed of the vehicle after entering the charging tunnel. Specifically, after the pantograph controller 312 establishes a wireless connection with the on-board controller 322, the vehicle controller 323 limits the maximum traveling speed of the vehicle, preventing the vehicle from being inconveniently parked due to an excessively high speed; accordingly, the vehicle control unit 323 releases the limitation on the maximum traveling speed of the vehicle after the pantograph controller completes the pantograph lifting operation.
It should be emphasized that in the present embodiment, the pantograph controller 312 controls the lowering of the head of the pantograph 313 to the position of the roof electrode plate 321 by using the flipping cylinder, and maintains the contact between the head of the pantograph 313 and the electrode plate by using the pressing cylinder. And, in the process of the pantograph 313 descending from the high position to the low position, it is quickly turned to a position close to the roof in the initial stage, and the turning speed is reduced after approaching the roof to reduce the impact force generated when the pantograph contacts with the electrode plate.
Fig. 4 is a structural view of the pantograph according to the present embodiment. When the electric vehicle is in a proper parking position at the platform, the bow head descends to the pole plate position of the roof through the overturning electric cylinders on the two sides, and then the bow head and the pole plate are tightly pressed through the pressing electric cylinders, preferably, the pressure is kept at 80-120N. The turning motion in the process of lifting the pantograph is required to ensure quick lifting so as to reduce the total charging time, and is required to decelerate at the tail end of the motion so as to buffer the impact force when the pantograph is contacted with the polar plate, so that the support is prevented from being deformed and damaged. The motion curve is shown in fig. 5.
The compression movement of the pantograph head to the roof electrode plate is to apply a certain positive pressure to the guide electrode plate between the pantograph and the roof under the condition of larger pitching and side swinging of the vehicle or uneven road so as to ensure that the upper and lower electrode plates have sufficient contact rate and meet the requirement of large-current electrification. The positive pressure should not be too great, which would otherwise cause the copper plate to deform.
The control principle of the pantograph movement is shown in fig. 6, in the embodiment, an electric cylinder of a product integrating a servo motor and a lead screw is used as an execution element, the rotary motion of the servo motor is converted into linear motion, and the motion of high-precision position, speed and thrust is realized through a CAN bus and closed-loop control.
In addition, the platform equipment is provided with redundant cameras 316 connected to the machine room monitoring room through a wired network.
Because the platform pantograph 313 and the roof electrode plate 321 are out of sight of the driver, an all-weather image processing scheme is needed to assist the driver in driving in order to enable the driver to quickly and accurately enter the charging working position. Specifically, the pantograph controller 312 captures a roof video image by the camera 314, generates a pantograph simulated landing position from the built-in vehicle graphic information, the vehicle real-time traveling information, and the real-time image, merges the simulated landing point with the real-time image, and confirms a matching state. The vehicle-mounted display is preferably a double display screen, and the left side displays the real object image of the roof plate and the landing position of the pantograph head of the simulation pantograph; the right side displays a simulated vehicle position image and a simulated pantograph landing position.
After the platform device 310 and the vehicle-mounted device 320 complete the handshake confirmation, the pantograph controller 312 retrieves the two-dimensional CAD simplified model and the roof identification information of the vehicle type from the database, and then calculates the landing point position of the pantograph on the roof of the vehicle and forms a simulated image of the landing point according to the installation position of the platform device.
The pantograph controller 312 superimposes the image taken by the camera with the simulated image of the pantograph falling point to form a real-time animation image. Meanwhile, the pantograph controller 312 collects the vehicle speed information sent by the vehicle controller to form a simulated motion animation of the vehicle roof, and the motion animation is also overlapped with the simulated image of the pantograph falling point to form a simulated animation image so as to guide the driver to correct the vehicle direction.
The onboard controller 322 transmits the real-time image and the simulation image through a wireless route for restoration and division, and outputs the real-time image and the simulation image to the front-end display screen 324 in real time, as shown in fig. 7. And the left real-time display vehicle roof plate real object image and the simulated pantograph head landing position, and when the simulated pantograph head landing position is positioned in the picture frame boundary, the display real-time reminds the ok and reminds the driver to stop and charge. And the right side displays a real-time simulation roof image and a simulation pantograph falling position according to the vehicle speed, and a driver can adjust the vehicle position in real time according to the simulation image so that the pantograph falling position can be fast and accurate.
Therefore, the online charging system provided by the embodiment transplants the charger and the pantograph from vehicle-mounted installation to ground installation, so as to form an online charging technology based on a platform mode, avoid the limitation of the charger and the pantograph from the whole vehicle environment, fully integrate with other mature ground systems at present, and greatly improve the service performance and reliability of the online charging system.
The image monitoring equipment is installed on the platform, so that image recognition is realized, and a driver is guided to park and charge safely and accurately at the platform. The potential safety hazard that step voltage and overhead network line were electrified usually can be solved, wifi carries out the communication, solves the problem that platform machine and vehicle separation charge. The servo motor and the double cylinders are used as executing elements, the structure is convenient and effective, and high-precision position, speed and thrust action are realized through CAN bus and closed-loop control. In addition, the double electric cylinders can also play a role in redundancy protection.
Example two
The embodiment provides an online charging method for an electric vehicle. The flow of steps of the method is described below with reference to fig. 8.
In step S801, the vehicle enters the wireless network coverage area of the charging system when arriving, and automatically establishes a wireless connection, at which time the vehicle does not obtain the charging right and cannot activate the charging request. When the vehicle needs to be charged, a driver drives the vehicle to enter the charging channel, and the ETC recognition device positioned in front of or above the charging channel recognizes the vehicle identification information. And if the identification fails, carrying out manual card swiping identification.
Next, in step S802, handshake communication between the pantograph controller and the vehicle-mounted controller is started, the vehicle identification information includes a wireless module address of the vehicle-mounted controller, the pantograph controller queries a network node corresponding to the address, and establishes handshake connection with the node, thereby establishing a wireless route between the pantograph controller and the vehicle-mounted controller.
In step S803, it is determined whether the handshake was successful. If the handshake is successful, step S804 is executed, the vehicle controller of the electric vehicle exchanges charging data with the charging pantograph controller through the wireless route, the pantograph controller and the vehicle-mounted controller realize the wireless routing function, the charger data and the vehicle data are forwarded, and the vehicle controller and the battery management system BMS establish seamless CAN network connection with the charging machine controller. The vehicle controller limits the maximum vehicle speed of the vehicle, and the pantograph controller collects vehicle roof image information to perform track recognition and driving behavior prompt.
If the handshake is unsuccessful, step S805 is executed to switch to the standby wifi device. The pantograph controller judges whether wifi works normally or not, and if so, the wifi is switched to backup wifi; the vehicle-mounted controller judges whether wifi work is normal or not, and if so, the wifi work is switched to backup wifi; and if the controller wifi works normally and the handshake cannot be successful, the vehicle or the pantograph is guaranteed to be repaired.
After step S804, step S806 is performed, and the vehicle control unit controls the pantograph controller to perform a pantograph operation such that the pantograph is in contact with the electrode plates of the vehicle-mounted device after determining that the charging condition is satisfied. Specifically, after the vehicle is driven in place, a driver finishes parking, neutral position arriving and hand brake pulling operations; when the vehicle-mounted display terminal prompts charging permission information, a driver presses a bow-lowering button; the vehicle control unit recognizes the action and sends the action to the pantograph controller to realize pantograph lowering operation.
And then, the pantograph controller feeds back a pantograph lowering completion mark, the whole vehicle controller informs the BMS of allowing charging, and the BMS automatically starts to confirm the charging process of the charger.
Next, the vehicle control unit executes step S807 in a case where it is determined that the charging has been completed, the charging has failed, or the charging state is exited, and after confirming that the power outage condition is satisfied, controls the pantograph controller to execute the pantograph-lifting operation.
And when the fact that a driver cancels a 'bow falling' button is detected, the current to be charged is reduced to a safe range, and the vehicle control unit informs the pantograph controller to realize the bow rising operation. And the vehicle controller unlocks the vehicle and unlocks the speed limit for 20 km/h. And after the vehicle-mounted controller cannot detect the handshake confirmation information for 10s, the current connection is interrupted, and the speed limit is released. After the pantograph controller can not detect the handshake signal for 10s or detects a new incoming charging signal of ETC, the current connection is interrupted.
After the bow lifting is finished, the driver drives the vehicle to slowly leave; and when the coverage range of the wireless network is exceeded, the vehicle automatically exits the charging mode and cancels the low-speed limit. When new vehicle identification information arrives or network connection with the current charging vehicle is lost, the vehicle-mounted controller cuts off the existing charging connection and waits for a new charging task.
Although the embodiments of the present invention have been described above, the above description is only for the convenience of understanding the present invention, and is not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
