Description

Operation method of intelligent parking charging management system

Technical Field

The invention relates to an operation method of an intelligent parking charging management system, provides a mobile flexible charging system, enables a charging device to provide charging service for a plurality of parking spaces and improve the utilization efficiency of charging facilities by expanding the radiation range of the charging device, and belongs to the technical field of electric vehicle charging systems.

Background

The existing electric automobile charging pile usually adopts a form of one pile and one position, namely one charging pile corresponds to one parking space. The "one pile for one bit" form has many problems:

1. occupying the fuel vehicle: because a plurality of cities have certain parking space gaps, the phenomenon that the fuel vehicle occupies the parking space with the charging pile occurs sometimes; if the occupation measures such as ground lock and the like are adopted, although the reservation charging and the exclusive use of the special parking space can be realized, the utilization rate of parking space resources is reduced and the occupation is not paid;

2. because the parking operation cannot be standardized and the specific positions of the charging interfaces of the electric automobiles are different, the charging pile is often located at a position where the charging pile is inconvenient to connect with the electric automobiles, so that the operation is inconvenient, and the cables are easily damaged in the operation process; moreover, before charging, the user also needs to perform some operations on a charging pile interaction interface to complete the docking of charging information; the two points reduce the convenience of charging and increase the operation time; the time for completing the steps is about 30-60 seconds; of course, if the current charging pile is in fault, a large amount of time is wasted;

3. the public utility of charging stake utilization ratio is low: the utilization rate of a large number of public charging piles is less than 15 percent, and the utilization rate of a large number of public charging piles is even less than 10 percent; the low utilization rate also causes that the charging pile cannot be well maintained and the damage rate is increased to a certain extent; as the power of the monopile increases: the charging speed is improved; the disadvantages are that: the initial investment is increased, the idle time of the equipment is increased, and the influence on the power grid is increased; therefore, large-scale adoption of high-power quick charging equipment is not advisable;

4. private/special charging pile installation difficulty: the existing policy is that a fixed parking space is required to be arranged for installing a private charging pile, which is equal to frosting on snow for a cell with a problem of difficult parking;

moreover, with the increase of the quantity of the electric automobiles and the quantity of the charging piles, if the quantity of the electric automobiles reaches 30% by planning to 2030 years, the traditional fuel oil vehicle still has a large quantity of reserves; therefore, the problems cannot be alleviated, and the contradiction is more prominent.

Disclosure of Invention

Aiming at the problems of the prior art, the invention provides a mobile flexible charging system with centralized management; the technical scheme of the invention is as follows:

intelligence parking management system that charges, including parking area and parking area management system, its characterized in that: dividing a parking lot into a plurality of parking space groups, wherein each parking space group is composed of a plurality of adjacent parking positions, and each parking position can be used for parking an electric automobile; arranging a charging terminal system in each parking space group; the parking lot management system carries out unified scheduling management on each charging terminal system;

the charging terminal system includes: the charging system comprises a charging main control module, a mobile charging module and a monitoring module;

the charging main control module: the system is used for managing the charging request of the user and the charging process and is arranged near the corresponding parking space group;

a monitoring module: the charging main control module is connected with the charging main control module and is used for monitoring the running condition of the corresponding parking space group and searching an idle parking position; (usually, a high-level camera monitoring device is adopted, and the monitoring content comprises the use condition of the parking space and whether abnormal conditions exist in the charging process, such as heating, smoking, fire and the like)

The mobile charging module: the mobile charging module can move to the vicinity of each parking position in the parking space group; the charging main control module and the mobile charging module are kept connected through a telescopic power cable;

when a charging demand is generated, the mobile charging module is moved to a position near a specified parking position, and then the charging interface assembly is in butt joint with the electric automobile parked in the parking position and charges the electric automobile;

it should be noted that: parking positions in the parking space group governed by each charging terminal system are allowed to be partially overlapped, for example, parking spaces located at positions on the outer side edge of the parking space group;

furthermore, the charging main control module can be simultaneously connected with a plurality of mobile charging modules 3 and carries out unified scheduling management on the mobile charging modules; the charging service can be provided for a plurality of parking positions in the parking space group at the same time.

Furthermore, the intelligent parking charging management system adopts a parking reservation charging operation mode, the electric automobile sends charging request information before parking, the parking lot management system searches for an idle parking position through the monitoring modules in the charging terminal systems and sends the idle parking position information to the electric automobile, the mobile charging module is moved to a position close to a specified parking position in the parking time period of the electric automobile, and after the electric automobile is parked, the mobile charging management system is connected with the electric automobile through the charging interface assembly and performs charging operation.

Furthermore, the parking space group corresponding to each charging terminal system at least comprises ten parking positions, each charging terminal system comprises at most five mobile charging modules, and the charging power of each mobile charging module is set to be less than 2 kilowatts; each mobile charging module operates independently, and can charge electric vehicles in different parking positions in the parking position group at the same time.

It should be noted that: in order to reduce investment and ensure that the keeping quantity of the electric automobiles is lower than 30 percent for a long time, a charging terminal system manages 10-20 parking positions reasonably and efficiently; the number of the mobile charging modules configured in the charging terminal system is far lower than the number of the managed parking positions, which is also necessary;

at the moment, the distance between the parking position at the far end and the charging main control module can reach dozens of meters, and in order to ensure the safety of the system and ensure the good operation of the mobile charging module, the telescopic power cable has a smaller diameter so as to support the working mode of frequent telescopic and retraction of the power cable; therefore, in order to reduce the diameter of the power cable and reduce the phenomenon of heat generation of the ultra-long cable in the long-time charging process, the charging power of each mobile charging module is set to be less than 2 kilowatts;

moreover, the design is also made for a large number of passenger vehicles with daily average driving mileage less than 50 kilometers, and the passenger vehicles usually only need to supplement 8-10KWH of electric quantity every day, namely, the daily electricity supplementing requirements of users can be met only by utilizing the valley power time and 1KW of charging power; the prerequisite is, of course, that charging must be very convenient, i.e. as far as possible "charge-as-stop". The technical scheme of the invention aims to solve the problems of convenience in installation and use of charging facilities and cost reduction, thereby realizing convenient charging in a large range.

Taking the current stage as an example, the holding capacity of the electric automobile is less than 10%, and if one charging terminal system governs 20 parking positions, 1-2 mobile charging modules are configured in the charging terminal system;

when the holding capacity of the electric automobile gradually increases to 15-20%, configuring 2-3 mobile charging modules in the charging terminal system;

when the holding capacity of the electric automobile gradually rises to 25-30%, 4-5 mobile charging modules are configured in the charging terminal system;

if too many mobile charging modules are connected in the charging terminal system, the complexity of cable management of each mobile charging module is increased, which is not favorable for the stable operation of the system;

therefore, with the implementation of the traditional fuel vehicle sale prohibition measures, the holding capacity of the electric vehicle will be rapidly increased, and at this time, the density and the number of the charging terminal systems should be gradually increased to meet the application requirements.

The intelligent parking charging management system adopts a parking reservation charging operation mode, an electric vehicle sends charging request information before parking, the parking lot management system searches for an idle parking position through a monitoring module in each charging terminal system and sends the idle parking position information to the electric vehicle, the mobile charging module is moved to a position close to an appointed parking position in the parking time period of the electric vehicle, and after the electric vehicle is parked, the mobile charging management system is connected with the electric vehicle through the charging interface component and performs charging operation.

The operation method of the intelligent parking charging management system specifically comprises the following procedures:

s1: when an electric automobile enters or is ready to enter a parking lot for parking and has a charging requirement, the electric automobile (such as an electric automobile control system, a driver mobile phone or other vehicle-mounted intelligent terminals and the like) sends charging request information through a network;

s2: after receiving the charging request information, the parking lot management system retrieves and analyzes the state of each charging terminal system and reserves an available idle parking position; the specific search conditions are:

firstly, a charging terminal system is provided with an idle mobile charging module; secondly, detecting that the managed parking space group has an idle parking position through a monitoring module in the charging terminal system;

the parking lot management system completes preparation work such as user identity authentication, charging request docking and the like according to the charging request information, and can also preferentially select a convenient parking position for the electric automobile or select a special parking position corresponding to the electric automobile according to the charging request information;

s3: the parking lot management system sends the preset idle parking position information to the electric automobile;

s4: the electric automobile drives to a specified parking position to park according to the guidance of the idle parking position information; meanwhile, the charging terminal system corresponding to the parking position operates, and one idle mobile charging module is moved to the parking position;

s5: after the electric automobile stops, the mobile charging module is already at a position near the electric automobile; at this time, the charging interface assembly in the mobile charging module is connected with the electric automobile and performs charging operation.

Furthermore, the parking lot management system realizes the locking of the idle parking position through the mobile charging module, namely, the mobile charging module moves into the idle parking position and parks the parking position, so that the parking position is in a temporarily occupied state; when an appointed vehicle arrives at the parking position, the mobile charging module moves to the periphery of the parking position, so that the appointed vehicle can be parked in the parking position; the specific application scenarios include:

firstly, after the electric automobile sends out charging request information and finishes reserving a parking charging position, the electric automobile needs some time to arrive at the parking position; during the period, the designated parking position is locked by the mobile charging module, so that the parking position can be prevented from being occupied by other vehicles;

second, when the parking quantity in the parking area is more, the parking stall is supplied with inadequately, if the demand that needs priority guarantee electric automobile parks or charge, then can only open to electric automobile through removing the module of charging and locking a plurality of idle parking stall temporarily.

The invention has the advantages that:

1. the limit of one pile and one position is broken through, one pile and multiple positions are realized, and the management problem of occupying the fuel vehicle is avoided;

2. the limiting condition that a fixed parking space is required when the charging pile is installed is eliminated, and the popularization and the application of private/special charging piles are facilitated;

3. through network reservation and intelligent positioning of the mobile charging module, the time for completing charging connection operation after a user stops is shortened to 5-10 seconds; the user charging experience is greatly improved;

4. a large number of parking positions of a parking place can be covered only by building a small number of charging facilities, and the actual condition of low maintenance of the electric automobile is met; thereby supporting the 'stop and charge' of the electric automobile; the overall investment is reduced, and the utilization rate of the charging facility is improved;

5. the charging facility can be configured progressively: when the holding capacity of the electric automobile is gradually increased, the expansion of the charging application can be realized only by gradually increasing the number of the mobile charging modules in each charging terminal system or increasing the density of the charging terminal system;

6. when the 'stop and charge' is realized, the economy and convenience of the electric automobile can be obviously improved and comprehensively surpass the traditional fuel oil automobile, and the mileage anxiety of a user can be eliminated.

Detailed Description

The embodiments of the present invention will be further described below with reference to the accompanying drawings.

Example 1:

as shown in fig. 1 to 5, the mobile charging module 3 in the charging terminal system of the present invention is a mobile intelligent vehicle.

The charging terminal system comprises a power cable winding mechanism 5;

a power cable winding mechanism 5a is arranged in the charging main control module 2, or/and a power cable winding mechanism 5b is arranged in the mobile charging module 3; for the extension or housing of the power cable 4; the mobile charging module 3 can move to any parking position in the parking space group 1 through the extension or the accommodation of the power cable 4, and is always kept in a connection state with the charging main control module 2 through the power cable 4; specifically, the method comprises the following steps:

when the distance between the charging main control module 2 and the mobile charging module 3 increases, the power cable winding mechanism 5 operates in the forward direction, so that the power cable 4 accommodated in the power cable winding mechanism 5 is gradually extended;

when the distance between the charging main control module 2 and the mobile charging module 3 is reduced, the power cable winding mechanism 5 operates in reverse direction, so that the power cable 4 is retracted and stored back into the power cable winding mechanism 5.

The mobile charging module 3 cooperates with the power cable winding mechanism 5 in the movement process, so that the extended length of the power cable 4 is basically consistent with the effective distance between the charging main control module 2 and the mobile charging module 3. Neither can excess cable be released to reduce uncertainty; nor can less cable be released, resulting in a situation where the cable is pulled.

It should be noted that, the specific manner of connecting the mobile charging module 3 with the vehicle-mounted charging interface of the electric vehicle includes:

1. the mobile charging module 3 comprises a charging plug 3a, and the charging plug 3a is connected with a vehicle-mounted charging socket of the electric automobile;

2. the charging electric automobile comprises a vehicle-mounted charging plug, and the charging plug is connected with a charging socket on the mobile charging module 3;

3. adopt wireless mode, the wireless output assembly that charges that will remove the module 3 that charges removes the position department that receives the subassembly that charges to electric automobile's wireless, accomplishes the butt joint and charges.

The specific operation process of the intelligent parking charging management system is as follows:

firstly, arranging a charging main control module 2 in the middle of a parking space group 1;

at this time, as shown in fig. 1, the mobile charging module 3 is located at the initial position;

s2: after receiving the charging request information, the parking lot management system retrieves and analyzes the state of each charging terminal system and reserves an available idle parking position;

at this time, as shown by the arrow direction in fig. 1, the electric vehicle moves to the parking position, and the mobile charging module 3 also moves to a predetermined idle parking position;

at this time, as shown in fig. 3, the electric vehicle is parked in place, and the mobile charging module 3 also reaches the predetermined position;

s5: after the electric automobile stops, the mobile charging module is already at a position near the electric automobile; at the moment, connecting the charging interface assembly in the mobile charging module with the electric automobile and performing charging operation;

at this time, as shown in fig. 4, the charging plug 3a of the mobile charging module 3 is butted against a charging interface of the electric vehicle, and a charging operation is performed.

Further, the mobile charging module 3 comprises a camera monitoring component for identifying the identity information of the vehicle and monitoring the motion process of the vehicle; when the vehicle is parked at the designated parking position, the parking process of the electric vehicle is monitored through the camera monitoring assembly, the mobile charging module 3 is moved in a small range, and then the vehicle is parked at a position where the charging interface assembly and the electric vehicle are conveniently in butt joint charging.

Because the vehicle-mounted charging interfaces of the electric vehicles are different in position and different in parking directions, the position fine adjustment by moving the charging module is very necessary. As shown in fig. 4, when the charging interface of the electric vehicle is deviated to the left, the parking position of the motion module is also deviated to the left of the parking space, so that the charging connection is conveniently realized.

Further, the mobile charging module 3 comprises an information prompt component, and when the mobile charging module moves to a specified parking position, the information prompt component is started, and the information prompt component is displayed through a screen, or/and a voice prompt is used for guiding and prompting the vehicle. As shown in fig. 2, a display screen is used to prompt the license plate information of the reserved vehicle (as shown in a 123456); or a speaker is used to broadcast the license plate information of the reserved vehicle, etc.

And, the parking lot management system may implement locking of the vacant parking position by moving the mobile charging module 3, as shown in fig. 2, moving the mobile charging module 3 into the vacant parking position and parking it so that the parking position is in a temporarily occupied state.

In addition, as shown in fig. 5, the wired charging component in the mobile charging module 3 is replaced by a wireless charging output component, and a vehicle-mounted wireless charging receiving component is arranged below the vehicle body and close to the chassis; the mobile charging module 3 can be directly moved to the position below the vehicle or extend the wireless charging assembly from the main body, is placed below the vehicle and is in butt joint with the vehicle-mounted wireless charging receiving assembly to perform wireless charging.

It should be noted that the parking space group 1 in the drawings is a simplified representation, and in fact, vehicles may be parked at each parking position; in addition, the arrangement of parking spaces may be an irregular combination of arrangements.

Adopt "portable intelligent vehicle" scheme, the advantage is: the structure is simple, the path is flexible, the device is suitable for irregular terrains and paths, and the cost is low; the disadvantages are that: the protection performance is poor; the scheme is more suitable for being implemented in a closed parking place.

Example 2:

as shown in fig. 7, when a charging demand occurs, the moving mechanism 7d drives the mobile charging module 3 to move to a specified parking position, and at the same time, the power cable winding mechanism 5a lengthens the power cable 4; in order to move conveniently, the movable charging module 3 is in a contraction state in the moving process; after the mobile charging module 3 reaches the designated working position, the mobile charging module 3 is converted into an extended state so that a user can conveniently take and use the charging interface component 3 a;

then, as shown in fig. 8, the charging interface module 3a is connected to the electric vehicle, and a charging operation is performed.

The overhead track structure has the advantages that:

1. by arranging external frames such as a ceiling, a supporting structure and the like, cables, rails, a movement mechanism and a charging interface in the external frames are protected, and the use is convenient;

2. a structure for fixing and protecting the cable is arranged near the track, so that the cable is kept smooth all the time in the process of winding and unwinding;
