Detailed Description
The invention is described in further detail below with reference to the following figures and detailed description:
working scene of mobile charger robot for bus station
As shown in fig. 1, in the working scene of the mobile charging robot in the bus station, the mobile charging robot comprises a charging robot 1 (including a platform trolley 2), a mobile sliding rail 5, a robot standby cabin 13, charging induction terminals 4, 10 and 12, charging piles 3, 9 and 11, vehicles to be charged 6, 7 and 8, and the like. The charging port of the vehicle to be charged is usually positioned behind or laterally behind each vehicle, an intelligent charging induction terminal is fixedly installed on the ground near the position and used for storing a charging gun, inducing the parking state of the vehicle and carrying out communication interaction with the vehicle to be charged (an automatic vehicle charging control unit), and the charger robot is installed on a platform trolley which can move back and forth on a track to provide charging service for vehicles in a plurality of parking spaces in turn. When the charging robot is in an idle state, the charging robot automatically returns to the standby cabin at the tail end of the track, and the charging robot and related control equipment are prevented from being damaged due to long-term exposure in an outdoor environment.
Second, automatic charging control working process of charger robot
The automatic charging control flow of the charging robot is shown in fig. 2 and 3:
stage 1: automatically sensing vehicle charging demand and generating charging plan
When a vehicle to be charged runs into the specified parking space, the charging induction terminal induces the vehicle to be in place, initiates wireless communication with the vehicle, acquires the identity information of the vehicle, and sends the state change of the charging position and the identity information of the vehicle to the charging service background system.
If the charging service background has the charging demand information of the identity vehicle shared by the Internet of vehicles, the charging service background automatically generates an ordered charging plan in combination with the ordered power utilization requirement of the power distribution network; if the charging service background does not receive the vehicle charging demand information, the charging induction terminal communicates with the vehicle, the vehicle charging demand information is requested and sent to the charging service background, and the charging service background generates an ordered charging plan according to the vehicle charging demand information.
And the charging induction terminal starts automatic charging operation at regular time according to the ordered charging plan.
Stage 2:
and the electric vehicle receives the command of starting automatic charging and automatically opens the charging interface hatch cover of the vehicle.
The charging robot receives the command of starting automatic charging and moves to the vicinity of the charging induction terminal; grabbing a charging gun, and turning to a visual identification working position near a vehicle socket; after the three-dimensional coordinates of the vehicle socket are identified, the charging gun is automatically plugged, and a plugging in-place signal is sent to the charging pile. And then the robot releases the charging gun and retreats to the waiting cabin of the robot.
After receiving the signal that the charging gun is inserted in place, the charging pile detects whether the guide control signal in the charging loop is correct again, and after no error is confirmed, communication is established with the vehicle according to GB/T18487 and GB/T27930 standards, and the charging output power is controlled in real time by automatically combining with the load current-limiting control curve of ordered charging.
During charging, the charging induction terminal continuously inquires the charging state of the charging vehicle, if charging is completed, the charging induction terminal informs the charging pile to stop outputting, and the charging robot is started to pull out the gun.
The charging robot receives the gun pulling operation instruction, reaches the position near the vehicle interface, grabs the charging gun and pulls out and inserts the charging gun back into the charging gun storage position of the charging induction terminal.
And the charging induction terminal detects that the charging gun is returned, and informs the charging vehicle that the charging is finished.
And the electric vehicle receives the command of finishing the charging, and automatically closes the charging interface hatch cover.
Orderly charging control method for electric automobile
Along with the popularization of city electric buses, the vehicle charge amount is gradually increased, and higher requirements are provided for the construction of a power distribution network. Time-sharing multiplexing of existing power distribution capacity, particularly charging of vehicles at night using off-peak electricity periods, is an effective method for solving this problem. However, the existing electric vehicles generally have the problems that the charging connection cannot be performed in advance, the charging is started at a later period in a timing mode (the vehicles can enter a dormant state, and the charging gun needs to be unplugged and plugged again when awakened), and if the night charging is to be realized, workers need to be on duty. The automatic charging mode of the charging robot is adopted, the night field operation of workers can be avoided, the economic operation of the power grid is effectively realized by utilizing the ordered charging control technology, and the capital construction investment of the power grid is reduced.
The ordered charging control method of the electric vehicle is shown in fig. 4:
after the electric vehicle is parked in the charging parking place, the charging induction terminal acquires the parking state of the vehicle, identifies the identity information of the vehicle and sends the identity information to the charging service platform. The electric vehicle sends the battery state (charging requirement) of the electric vehicle to the Internet of vehicles platform, and the Internet of vehicles platform also sends the vehicle charging requirement and the vehicle scheduling plan to the charging service platform.
The charging service platform can acquire the power distribution network operation flow control information of the power production management system. And generating an ordered charging plan according to a charging load control algorithm by combining charging demand data from the Internet of vehicles platform and the charging induction terminal, and issuing the ordered charging plan to the charging induction terminal.
The charging induction terminal controls the charging robot in a timing mode according to the ordered charging plan, starts charging connection operation, controls power output of the charging pile in real time during charging, and finishes ordered control of power load of the whole charging process.
In summary, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can propose other embodiments within the technical teaching of the present invention, but these embodiments are included in the scope of the present invention.
