Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging, and in particular to a port electric vehicle charging method and system. Background Art

[0002] In the early stage of port construction in my country, due to the limitations of electric vehicle technology at that time, all ports did not design and reserve charging sites for port electric vehicles. With the maturity of electric technology in recent years, the national energy-saving and environmental protection policy orientation and the urgent need for energy conservation and emission reduction by enterprises themselves, ports have gradually introduced port electric vehicles to replace traditional fuel vehicles. The existing available sites in ports can no longer meet the charging needs of traditional fuel vehicles after replacing pure electric vehicles. The limitations of sites and the number of charging piles have begun to limit the application and promotion of new energy port electric vehicles in ports.

[0003] Although the existing technology can confirm the remaining power of the rechargeable battery and determine the charging time through the dashboard of the port electric vehicle, the problem of limited number of charging sites and charging piles still exists, and the driver will only passively charge when the remaining power warning is given, which causes most port electric vehicles to charge in one time period, while other time periods are idle; at the same time, centralized charging brings problems such as congestion and queuing in the site, which prolongs the charging time of port electric vehicles and reduces the utilization rate of charging piles. In addition, port electric vehicles are all cyclically operated, and some port electric vehicles exit the operation sequence to charge, which will affect the operation efficiency of the entire operation line. This leads to the operation time and operation efficiency of new energy port electric vehicles in the port being shorter than traditional fuel vehicles, affecting the overall production operation efficiency of port users; at the same time, the driver of the port electric vehicle cannot intuitively judge the operation task, and each time the charging is passively charged after reaching the limit, the rechargeable battery is often used under extreme conditions, which greatly reduces the life of the rechargeable battery of the port electric vehicle.

[0004] Therefore, it is particularly important to propose a port electric vehicle charging method that avoids centralized charging, improves the utilization rate of charging piles, avoids affecting operating efficiency, and prolongs the service life of rechargeable batteries.

[0083] Implementation Method 1

[0084] In order to solve the technical problems of centralized charging, low utilization of charging piles, affecting operation efficiency, and affecting the service life of rechargeable batteries, this embodiment proposes a port electric vehicle charging method, which can be applied to port operations and other operation scenarios, such as warehousing operations and factory processing and handling operations. The method determines a target charging plan based on the battery power data, the charging status data, and the pending operation data. The target charging plan is used to control the charging of the port electric vehicle, which is conducive to avoiding centralized charging, improving the utilization rate of charging piles, avoiding affecting operation efficiency, and extending the service life of rechargeable batteries.

[0085] like Figure 1 As shown, in one embodiment, a port electric vehicle charging method is proposed, which is applied to a port electric vehicle charging system. The system includes: a port electric vehicle, a charging pile, and an operation scheduling device. The port electric vehicle is used for port operations, the charging pile is used to charge the port electric vehicle, and the operation scheduling device is used to schedule the port electric vehicle to perform port operations. The method includes:

[0086] S102, obtaining battery power data of the port electric vehicle;

[0087] The battery power data may be actively sent by the port electric vehicle, or may be sent by the port electric vehicle in response to an electric vehicle data upload instruction.

[0088] The electric vehicle data upload instruction is sent to the port electric vehicle by a program module that executes the port electric vehicle charging method.

[0089] Optionally, the battery power data includes: electric vehicle identification, detection time, and battery power measurement value.

[0090] The electric vehicle identification may be an identification such as an ID or a name that uniquely identifies a port electric vehicle.

[0091] The detection time is a specific time point.

[0092] The battery power measurement value refers to the power of the battery of the port electric vehicle at the detection time.

[0093] Optionally, the battery power data also includes: total battery power capacity.

[0094] The total battery capacity refers to the amount of power when the battery of the port electric vehicle is fully charged.

[0095] Optionally, the total battery capacity of different port electric vehicles may be the same or different.

[0096] Optionally, the battery power data may be data of all port electric vehicles in the port.

[0097] Optionally, the battery power data may be data of all electric vehicles in the port that are not being charged.

[0098] S104, obtaining charging status data of the charging pile;

[0099] The charging status data may be actively sent by the charging pile, or may be sent by the charging pile in response to a charging pile data upload instruction.

[0100] The charging pile data upload instruction is sent to the charging pile by a program module that executes the port electric vehicle charging method.

[0101] The charging status data includes: charging pile identification, detection time, and charging status.

[0102] The charging pile identifier may be an identifier such as an ID or a name that uniquely identifies a charging pile.

[0103] The charging state includes a charging state and an idle state.

[0104] S106, obtaining the job data to be processed of the job scheduling device;

[0105] The pending job data may be actively sent by the job scheduling device, or may be sent by the job scheduling device in response to an instruction to upload the pending scheduling data.

[0106] The to-be-processed scheduling data upload instruction is sent to the operation scheduling device by a program module that executes the port electric vehicle charging method.

[0107] The pending job data includes: sending time, expected start time of the pending job, expected end time of the pending job, and workload of the pending job.

[0108] The sending time is used to express the time when the to-be-processed job data is sent, and is a specific time point.

[0109] The workload of pending operations is used to express the number of port electric vehicles required for pending operations.

[0110] It is understandable that the pending job data may be data of all pending jobs, or data of pending jobs within a preset time after the sending time. For example, if the sending time is 11:00, the pending job data may be data of pending jobs between 11:00 and 12:00.

[0111] S108. Determine a target charging plan according to the battery power data, the charging status data and the pending operation data, wherein the target charging plan is used to control the charging of the port electric vehicle.

[0112] Wherein, the chargeable quantity is determined according to the pending job data and the battery power data; and the target charging plan is determined according to the charging state data, the chargeable quantity and the battery power data.

[0113] It is understandable that the determined target charging plan needs to satisfy the pending operation data, not affect the battery life of the electric vehicles in the port, and cannot exceed the number of available charging piles.

[0114] The target charging plan includes: electric vehicle identification, charging pile identification, and charging pile location data.

[0115] Optionally, the target charging plan further includes: an estimated charging time. The estimated charging time can be used to predict the time when the port electric vehicle in the target charging plan can be put into operation again.

[0116] Optionally, the target charging plan may be data for one batch of batteries that need to be charged, or may be data for multiple batches of batteries that need to be charged.

[0117] The one batch refers to the same time of sending charging instructions to the operating terminal equipment on the port electric vehicles.

[0118] The multiple batches refer to the time when the charging instruction is sent to the operation terminal device on the port electric vehicle. By determining that the target charging plan contains multiple batches of data that need to be charged at one time, the number of times the target charging plan is determined can be reduced.

[0119] Optionally, in the same target charging plan, the same electric vehicle identifier may have one charging plan or multiple charging plans.

[0120] It can be understood that the first implementation mode is described by taking the target charging plan as an example in which only one batch of data requiring charging is included.

[0121] It is understandable that, when the target charging plan contains data for multiple batches that need to be charged, the target charging plan can be confirmed in multiple times, with only one batch of data that needs to be charged being confirmed each time.

[0122] The method of this embodiment determines a target charging plan based on the battery power data of the port electric vehicles, the charging status data of the charging piles, and the pending job data of the job scheduling equipment. The target charging plan is used to control the charging of the port electric vehicles, thereby associating the target charging plan with the battery power data, the charging status data, and the pending job data. When controlling the charging of the port electric vehicles according to the target charging plan, it will be beneficial to avoid centralized charging, improve the utilization rate of the charging piles, avoid affecting the operating efficiency, and extend the service life of the rechargeable batteries.

[0123] like Figure 2 As shown, in one embodiment, determining a target charging plan according to the battery power data, the charging status data and the pending operation data includes:

[0124] S202, determining the required number of jobs to be processed according to the job data to be processed;

[0125] Wherein, the required number of jobs to be processed is determined according to the data of the jobs to be processed and preset rules.

[0126] The number of pending job demands is the number of job demands that need to be met to determine the target charging plan.

[0127] It can be understood that the required number of jobs to be processed may be the total required number of jobs of the job data to be processed, or may be the partial required number of jobs of the job data to be processed.

[0128] The operation demand quantity refers to the quantity of the port electric vehicles required for port operations.

[0129] S204, determining the chargeable quantity according to the battery power data, the first battery power threshold, and the required quantity of the to-be-processed jobs;

[0130] Optionally, the battery power data is compared with a first battery power threshold, and the number of the port electric vehicles whose battery power data is greater than or equal to the first battery power threshold is used as the first battery safety number; when the number of pending operation requirements is less than or equal to the first battery safety number, the number of the port electric vehicles whose battery power data is less than the first battery power threshold is used as the rechargeable number; when the number of pending operation requirements is greater than the first battery safety number, the first battery safety number is subtracted from the number of pending operation requirements to obtain the number of unsatisfied operation requirements, and the number of unsatisfied operation requirements is updated to the unsatisfied operation list. This achieves maximum protection of the battery life of the port electric vehicle.

[0131] Optionally, the battery power data is compared with a first battery power threshold, and the number of the port electric vehicles whose battery power data is greater than or equal to the first battery power threshold is taken as the first battery safety number; when the number of pending job demands is less than or equal to the first battery safety number, the number of the port electric vehicles whose battery power data is less than the first battery power threshold is taken as the rechargeable number; when the number of pending job demands is greater than the first battery safety number, the second battery safety number is determined according to the battery power data and the second battery power threshold; the number of pending job demands is compared with the second battery safety number; when the number of pending job demands is less than or equal to the second battery safety number, the total number of the port electric vehicles is obtained, and the number of pending job demands is subtracted from the total number of the port electric vehicles to obtain the rechargeable number; when the number of pending job demands is greater than the second battery safety number, the number of pending job demands is subtracted from the second battery safety number to obtain the number of unsatisfied job demands, and the number of unsatisfied job demands is updated to the unsatisfied job list; wherein, the first battery power threshold is greater than the second battery power threshold. By having the first battery power threshold and the second battery power threshold being larger, the life of the battery of the port electric vehicle is protected while the number of operations to be processed is met as much as possible, which is conducive to improving the port operation efficiency.

[0132] Optionally, the first battery power thresholds corresponding to different port electric vehicles may be the same or different.

[0133] S206: Determine the target charging plan according to the charging status data, the chargeable quantity and the battery power data.

[0134] Among them, the target charging quantity is determined according to the charging status data and the chargeable quantity; and the target charging plan is determined according to the target charging quantity and the battery power data.

[0135] The target charging plan is determined according to the target charging quantity and the battery power data, including: finding the same number of port electric vehicles as the target charging quantity as the target charging electric vehicles based on the minimum value of the battery power measurement value of the battery power data, and using the electric vehicle identifiers corresponding to the target charging electric vehicles as the electric vehicle identifiers of the target charging plan; finding the same number of charging piles as the target charging quantity from idle charging piles as the target charging piles, using the charging pile identifiers corresponding to the target charging pile vehicles as the charging pile identifiers of the target charging plan, and using the charging pile location data corresponding to the target charging pile vehicles as the charging pile location data of the target charging plan.

[0136] This embodiment determines a target charging plan based on the battery power data, the charging status data, the first battery power threshold, and the pending job data, and associates the target charging plan with the battery power data, the charging status data, the first battery power threshold, and the pending job data, thereby protecting the battery life of the port electric vehicle while satisfying the pending job data.

[0137] In one embodiment, determining the required number of jobs to be processed based on the job data to be processed includes: determining the required number of jobs to be processed based on the job data to be processed and an interval duration list.

[0138] The time in the interval duration list may be equal intervals or unequal intervals. For example, when the time in the interval duration list is equal intervals, it may be 8:00-9:00, 9:00-10:00, 10:00-11:00, 11:00-12:00, 12:00-13:00, 13:00-14:00, 14:00-15:00, 15:00-16:00, 16:00-17:00; when the time in the interval duration list is unequal intervals, it may be 8:00-10:00, 10:00-11:00, 11:00-12:00, 12:00-13:00, 13:00-14:00, 14:00-15:00, 15:00-17:00, and no specific limitation is given in this example.

[0139] Optionally, the number of job requirements at a single time point in each time period of the interval duration list is determined from the pending job data, and the maximum number of job requirements at a single time point in each time period is used as the pending job requirements corresponding to each time period. For example, the time period of the interval duration list is 11:00-12:00, the number of job requirements at a single time point (any time point between 11:00-12:00) between 11:00-12:00 is determined from the pending job data, and the maximum number of job requirements at a single time point between 11:00-12:00 is used as the pending job requirements corresponding to 11:00-12:00, and no specific limitation is made in this example.

[0140] Optionally, the time in the interval duration list can be designed according to the busyness of the port operation. When the port operation is busy, the interval duration of the time in the interval duration list is set short, and when the port operation is idle, the interval duration of the time in the interval duration list is set long (which means the interval duration is long relative to when the port operation is busy).

[0141] This embodiment determines the number of pending job demands based on the pending job data and the interval duration list, fully considering the number of pending job demands in each time period, avoiding the impact on port operation efficiency due to inaccurate number of pending job demands, and reducing the frequency of determining the target charging plan.

[0142] like Figure 3 As shown, in one embodiment, determining the required number of jobs to be processed according to the job data to be processed and the interval duration list includes:

[0143] S302, determining the required quantity of the first operation according to the to-be-processed operation data and the interval duration list;

[0144] Optionally, the number of job requirements at a single time point in each time period of the interval duration list is determined from the pending job data, and the maximum number of job requirements at a single time point in each time period is taken as the first job requirement corresponding to each time period.

[0145] S304, obtaining historical operation data of the operation scheduling device;

[0146] The historical job data may be actively sent by the job scheduling device, or may be sent by the job scheduling device in response to a historical scheduling data upload instruction.

[0147] The historical scheduling data upload instruction is sent to the operation scheduling device by a program module that executes the port electric vehicle charging method.

[0148] The historical operation data includes: operation time, operation start time, operation end time, and operation workload.

[0149] The operational workload refers to the number of port electric vehicles used for the operation.

[0150] S306, determining the required quantity of the second operation according to the historical operation data, the to-be-processed operation data, and the interval duration list;

[0151] Among them, the mean calculation is performed based on the historical operation data and the preset number of days to obtain the historical operation average data; when the historical operation average data is greater than the operation data to be processed, the operation demand difference is obtained by subtracting the operation data to be processed from the historical operation average data, and the second operation demand quantity is determined according to the operation demand difference; when the historical operation average data is less than the operation data to be processed, the preset value is used as the second operation demand quantity.

[0152] The method of performing mean calculation based on the historical operation data and the preset number of days to obtain the historical operation average data includes: taking the operation data of the preset number of days as the operation data to be calculated based on the historical operation data, and performing mean calculation on the operation workload at the same time point every day for the operation data to be calculated to obtain the historical operation average data. For example, performing mean calculation on the operation workload at 10 o'clock every day in the operation data to be calculated to obtain the historical operation average data corresponding to 10 o'clock, which is not specifically limited in this example.

[0153] The same time point every day refers to the same time point every day, for example, 1 o'clock every day, and no specific limitation is given in this example.

[0154] The step of subtracting the to-be-processed job data from the historical job average data to obtain the job demand difference includes: subtracting the to-be-processed job data at the same time point every day from the historical job average data to obtain the job demand difference.
