[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0046] Example 1

[0047] Figure 1 This is a flowchart of a smart charging method according to Embodiment 1 of the present invention. Figure 1 As shown, a smart charging method includes:

[0048] S100: Obtain the first moment when the charging gun is inserted into the charging station, and the second moment when the charging gun is pulled out of the charging station.

[0049] The first moment can be the moment when the user inserts the charging gun into the charging station according to charging needs; the second moment can be the moment when the user removes the charging gun from the charging station according to usage needs. The first moment and the second moment can be set by the user according to their needs. The time interval between the first moment and the second moment is the charging range selected by the user, and the charging period can be further selected based on the charging range.

[0050] S200: Obtain the charging time setting direction of the charging pile into which the charging gun is inserted. The charging time setting direction includes forward charging state and reverse charging state. In forward charging state, the charging time is set from the first moment to the second moment. In reverse charging state, the charging time is set from the second moment to the first moment.

[0051] The forward charging state can be defined as the charging period designed from the moment the charging gun is inserted into the charging pile towards the moment it is removed from the charging pile. The reverse charging state can be defined as the charging period designed from the opposite direction. When designing the charging period (not the actual charging sequence, which is always executed sequentially from front to back), the forward charging state aims to place the charging period as close as possible to the moment the charging gun is inserted into the charging pile, while the reverse charging state aims to place the charging period as close as possible to the moment the charging gun is removed from the charging pile.

[0052] S300: Set the direction according to the charging period and control the charging gun to charge the battery.

[0053] Specifically, the charging time of the battery in the forward charging state is controlled according to the forward charging state set during the charging period; the charging time of the battery in the reverse charging state is controlled according to the reverse charging state set during the charging period.

[0054] For example, the first moment when the charging gun is inserted into the charging pile can be defined as T1, and the second moment when the charging gun is removed from the charging pile can be defined as T2. Based on the user's power demand, the first moment T1 and the second moment T2 are obtained, resulting in a charging range of [T1, T2]. A charging period is selected based on this range. The setting direction of the charging period for the charging pile into which the charging gun is inserted is obtained. When the setting direction is forward charging, the charging time is set from the first moment T1 towards the second moment T2; when the setting direction is reverse charging, the charging time is set from the second moment T2 towards the first moment T1. The charging gun is then controlled to charge the battery according to the set charging time.

[0055] This invention, through obtaining the charging ranges of different users, selects different charging periods for batteries based on these ranges. This ensures that the charging periods vary across different charging ranges, alleviating grid load during peak electricity demand when batteries are charging simultaneously. It also reduces the probability of grid line and equipment overload and improves grid reliability. Furthermore, by setting the charging direction according to the charging period, it further balances battery charging time, avoiding the problem of concentrated charging at the same time.

[0056] Optionally, the charging period setting direction of the charging station into which the charging gun is inserted can be obtained, including:

[0057] Find the area where the charging station is located.

[0058] Based on the region, obtain the charging period setting direction of the charging station into which the charging gun is inserted.

[0059] Among them, the charging time period setting direction of the charging pile can be divided according to the charging pile area. The location information of the charging pile can be obtained by obtaining the area where the charging pile is located, and the charging time period setting direction of the charging pile in this area can be determined based on the location information of the charging pile.

[0060] For example, this area is divided into a first area and a second area. The charging period of the charging piles in the first area is set to the forward charging state, and the charging period of the charging piles in the second area is set to the reverse charging state. When the user inserts the charging gun into the charging pile, the area where the charging pile is located is determined. If the area where the charging pile is located is the first area, the charging period of the charging pile is set to the forward charging state; if the area where the charging pile is located is the second area, the charging period of the charging pile is set to the reverse charging state.

[0061] By dividing the charging time slots of charging piles into regions and setting the charging time slots in a fixed direction, users can select the appropriate charging pile. The charging pile will then evenly distribute the forward and reverse charging states according to its own charging time slot setting direction, thus avoiding the concentration of battery charging during peak electricity consumption periods and improving the reliability of the power grid.

[0062] Optionally, the charging period setting direction of the charging station into which the charging gun is inserted can be obtained, including:

[0063] In response to the user's selected charging command, the charging period setting direction of the charging station into which the charging gun is inserted is obtained.

[0064] The charging command can set the direction for the charging period, which includes forward charging and reverse charging.

[0065] For example, after the charging gun is inserted into the charging station, the user needs to manually select whether the charging period is set to forward or reverse charging. After the user selects the charging command, the system calculates the corresponding charging time based on the set charging period and controls the charging gun to charge the battery.

[0066] By allowing users to choose the charging time period setting, user participation in the charging system is enhanced. This also helps alleviate the problem of concentrated battery charging during peak electricity consumption periods and improves the reliability of the power grid.

[0067] Optionally, the charging period setting direction of the charging station into which the charging gun is inserted can be obtained, including:

[0068] Based on the number of charging piles in the forward charging state and the number of charging piles in the reverse charging state, select the charging period setting direction for the charging piles.

[0069] For example, when a user inserts a charging gun into a charging station, if the number of charging stations in the forward charging state is greater than the number of charging stations in the reverse charging state, the charging station selects the charging period setting direction as the reverse charging state; when the number of charging stations in the forward charging state is less than or equal to the number of charging stations in the reverse charging state, the charging station selects the charging period setting direction as the forward charging state.

[0070] By comparing the number of charging piles in the forward charging state with the number of charging piles in the reverse charging state in the power supply system, the charging piles select the setting direction for the corresponding charging period based on the comparison of the number of charging directions during the charging period, so that the setting direction of the charging period of the charging piles can achieve dynamic balance and reduce the probability of grid overload.

[0071] Optionally, based on the number of charging piles in the forward charging state and the number of charging piles in the reverse charging state, the charging period setting direction of the charging piles can be selected, including:

[0072] Based on the cumulative number of charging piles in the forward charging state and the cumulative number of charging piles in the reverse charging state, select the charging period setting direction for the charging pile.

[0073] The cumulative quantity is the sum of the quantities from the preset time to the first time.

[0074] The preset time can be any time of day. The total number of charging piles in the forward charging state from the preset time to the first time is the cumulative number of charging piles in the forward charging state; the total number of charging piles in the reverse charging state from the preset time to the first time is the cumulative number of charging piles in the reverse charging state.

[0075] For example, the cumulative number of charging piles in the forward charging state is the cumulative number of charging piles in the power supply system in the forward charging state starting from 0:00 each day; the cumulative number of charging piles in the reverse charging state is the cumulative number of charging piles in the power supply system in the reverse charging state starting from 0:00 each day. After the user inserts the charging gun into the charging pile, when the cumulative number of charging piles in the forward charging state is greater than the cumulative number of charging piles in the reverse charging state, the charging period setting direction of the selected charging pile is reverse charging; when the cumulative number of charging piles in the forward charging state is less than or equal to the cumulative number of charging piles in the reverse charging state, the charging period setting direction of the selected charging pile is forward charging.

[0076] By comparing the cumulative number of charging time periods set in the charging piles from the preset time to the first time in the power supply system, the battery charging time is balanced while simplifying the complexity of setting up the charging piles in the system.

[0077] Optionally, based on the number of charging piles in the forward charging state and the number of charging piles in the reverse charging state, the charging period setting direction of the charging piles can be selected, including:

[0078] Based on the real-time number of charging piles in the forward charging state and the real-time number of charging piles in the reverse charging state, select the charging period setting direction for the charging pile.

[0079] The real-time quantity refers to the quantity at the first moment.

[0080] When the charging gun is inserted into the charging pile, the charging pile obtains the real-time number of charging piles in the forward charging state and the real-time number of charging piles in the reverse charging state at this time. That is, the real-time number is the number of charging piles in the forward charging state and the number of charging piles in the reverse charging state at the first moment.

[0081] For example, the moment the charging gun is inserted into the charging pile is designated as the first moment. The charging pile acquires the number of charging piles in the forward charging state and the number of charging piles in the reverse charging state at this first moment. When the number of charging piles in the forward charging state is greater than the number of charging piles in the reverse charging state, the charging pile selects the charging period setting direction for the charging pile as the reverse charging state; when the number of charging piles in the forward charging state is less than or equal to the number of charging piles in the reverse charging state, the charging pile selects the charging period setting direction for the charging pile as the forward charging state.

[0082] By comparing the number of charging piles in the forward charging state and the number of charging piles in the reverse charging state in real time through the power supply system, the charging piles select the setting direction for the corresponding charging period based on the comparison of the number of charging directions during the charging period. This enables the setting direction of the charging period of the charging piles to achieve dynamic balance, more accurately balances the battery charging time, and reduces the probability of grid overload.

[0083] Optionally, before setting the direction according to the charging period and controlling the charging gun to charge the battery, the following is also included:

[0084] Obtain peak, off-peak, and valley time periods.

[0085] Get the charging time required to fully charge the battery.

[0086] The charging gun is controlled to charge the battery according to the direction set during the charging period, including:

[0087] Based on peak, off-peak, and valley periods and charging duration, set the charging time period according to the direction of the charging time period.

[0088] The charging gun is controlled to charge the battery according to the charging period.

[0089] Among them, the peak, off-peak, and valley periods can be calculated based on the concentration of electricity consumption in the power supply system, and are the peak electricity consumption period, off-peak electricity consumption period, and valley electricity consumption period between the first and second moments.

[0090] The charging time required to fully charge the battery can be obtained in the following ways:

[0091] Taking electric vehicle users as an example, according to relevant statistics, Figure 2 This is a probability distribution diagram of charging time for electric vehicle users provided according to Embodiment 1 of the present invention, such as... Figure 2 As shown, the charging times of electric vehicle users follow a normal distribution, and its probability density function is:

[0092]

[0093] Wherein, mean μ s Take 18, standard deviation σ s Take 1. Figure 3 This is a probability distribution diagram of the daily mileage of an electric vehicle provided according to Embodiment 1 of the present invention, such as... Figure 3 As shown, the daily mileage of an electric vehicle follows a log-normal distribution, and its probability density function is:

[0094]

[0095] Wherein, the expected value μ D The value is 3.2, and the standard deviation σ is 3.2. D It is 0.88.

[0096] The formula for calculating the time required to charge a single electric vehicle is as follows:

[0097]

[0098] Among them, T C d represents the charging time. c W represents the total mileage. 100 Power consumption per 100 kilometers; P C This refers to the charging power.

[0099] in,

[0100] Therefore, the charging time required to fully charge an electric vehicle battery can be calculated using the following formula.

[0101]

[0102] Among them, S OC The state of the electric vehicle's battery when charging (when fully charged) OC(1); B C This refers to the battery capacity of an electric vehicle.

[0103] Battery state S of an electric vehicle during charging OC The calculation formula depends on the electric vehicle's daily mileage and range, and is as follows:

[0104]

[0105] In the formula, d1 represents the range; d c Indicates the daily mileage.

[0106] Therefore, the charging time T of the electric vehicle is derived. C The probability density function is

[0107]

[0108] According to battery capacity B C Daily mileage d C Charging power P C Given the driving range d1, calculate the charging time T of the electric vehicle. C .

[0109] For example, the first moment when the charging gun is inserted into the charging pile is T1, and the second moment when the charging gun is pulled out of the charging pile is T2. The rechargeable range is [T1, T2].

[0110] The peak power supply periods are defined as: 14:00-17:00 and 19:00-22:00, totaling 6 hours; the off-peak power supply periods are: 8:00-14:00, 17:00-19:00 and 22:00-24:00, totaling 10 hours; and the off-peak power supply period is: 0:00-8:00, totaling 8 hours. Therefore, the peak, off-peak, and off-peak power consumption periods within the rechargeable range [T1, T2] can be obtained, denoted as T. 峰 T 平 and T 谷 And T2-T1=T 峰 +T 平 +T 谷 .

[0139] The process automatically ends when the battery is fully charged.

[0140] By combining charging periods and their settings with daily peak and off-peak electricity consumption times, different charging modes are selected. This alleviates the grid load on the grid when batteries are charging simultaneously during peak hours, reducing the probability of grid line and equipment overload and improving grid reliability. Furthermore, prioritizing charging during off-peak or normal periods while ensuring battery charging efficiency reduces user charging costs and increases user engagement.

[0141] This invention, through obtaining the charging ranges of different users, selects different charging periods for batteries based on these ranges. This ensures that the charging periods vary across different charging ranges, alleviating grid load during peak electricity demand when batteries are charging simultaneously. It also reduces the probability of grid line and equipment overload and improves grid reliability. Furthermore, by setting the charging direction according to the charging period, it further balances battery charging time, avoiding the problem of concentrated charging at the same time.

[0142] Example 2

[0143] This invention provides an intelligent charging device, which includes:

[0144] The first and second moment acquisition module 101 is used to acquire the first moment when the charging gun is inserted into the charging pile, and the second moment when the charging gun is pulled out of the charging pile.

[0145] The charging time period setting direction acquisition module 102 is used to acquire the charging time period setting direction of the charging pile into which the charging gun is inserted; the charging time period setting direction includes forward charging state and reverse charging state. In the forward charging state, the charging time is set from the first moment to the second moment, and in the reverse charging state, the charging time is set from the second moment to the first moment.

[0146] The charging module 103 is used to set the direction according to the charging period and control the charging gun to charge the battery.

[0147] For example, the first moment T1 when the charging gun is inserted into the charging pile and the second moment T2 when the charging gun is pulled out of the charging pile are obtained by the first moment and second moment acquisition module 101; when the charging gun is inserted into the charging pile, the charging period setting direction of the charging pile is obtained by the charging period setting direction acquisition module 102, and the charging module 103 controls the charging gun to charge the battery according to the charging period setting direction of the charging pile.

[0148] This invention, through obtaining the charging ranges of different users, selects different charging periods for batteries based on these ranges. This ensures that the charging periods vary across different charging ranges, alleviating grid load during peak electricity demand when batteries are charging simultaneously. It also reduces the probability of grid line and equipment overload and improves grid reliability. Furthermore, by setting the charging direction according to the charging period, it further balances battery charging time, avoiding the problem of concentrated charging at the same time.

[0149] Example 3

[0150] This invention also provides a computer device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements a smart charging method.
