[0003] Some users may have urgent matters and need emergency charging. However, the existing charging mechanism cannot meet the needs of customers for emergency charging, which reduces the user experience. Summary of the Invention

[0010] The power supply module (4), after being triggered, selects to cut off the power supply of at least one of the in-use charging piles according to the power-off duration and the urgent charging duration; within the power-off duration, the charging power of the power-off charging pile is allocated to the target charging pile for urgent charging;

[0011] An information storage module (6) for storing the power supply duration of the user and the remaining values of the power supply durations of each user; the information storage module (6) is connected to the receiving module (1) through an interface.

[0013] G1. The receiving module (1) receives the urgent request information sent by the user;

[0014] G2. The determination module (2) determines the target charging pile carried by the urgent request information and the urgent charging duration of the target charging pile;

[0015] G3. The acquisition module (3) acquires the power-off durations of other charging piles;

[0018] Compared with the prior art, the present invention can achieve the following technical effects:

[0019] In real life, each user has the need to fully charge the vehicle in a short time. Therefore, this application proposes a mechanism of contributing charging time in exchange for urgent charging according to the customer's needs. That is, the user spontaneously proposes the power-off duration to obtain the qualification for urgent charging. The purpose of urgent charging is to reduce the charging time, and reducing the time will inevitably lead to an increase in the charging pile power, which will increase the power supply load. For this reason, within the power-off duration provided by the user, the power supply of the corresponding charging pile is cut off, and the power of this charging pile is transferred to the charging pile for urgent charging (target charging pile). In the above way, on the premise of ensuring that the total power consumption load does not overload, that is, the existing users (excluding the users whose power is cut off due to urgent charging) have reliable power supply without power interruption, charging is provided for emergency users, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a schematic structural diagram of a charging pile operation device provided by one or more embodiments of this specification;

[0021] Figure 2 It is a flowchart of a charging pile operation method provided by one or more embodiments of this specification. DETAILED DESCRIPTION OF THE INVENTION

[0022] Embodiment 1: Refer to the appendixFigure 1 , a charging pile operation device, characterized by comprising:

[0023] A receiving module 1, configured to receive the urgent request information sent by a user, retrieve the relevant data of this user from an information storage module 6, and determine whether the urgent charging request is qualified according to preset conditions. If it is qualified, the determination module 2 is triggered; if it is unqualified, the urgent charging request is rejected and fed back to the user;

[0024] A collection module 5, configured to collect the power-off durations of each charging pile, connect to the obtaining module 3 and the information storage module 6 through an interface, and the power-off duration is the duration allowed for the charging pile where an online user is located to be powered off;

[0025] The determination module 2, after being triggered by the receiving module 1, triggers the obtaining module 3 according to the target charging pile carried in the urgent request information and the urgent charging duration required by the user;

[0026] The obtaining module 3, after being triggered, obtains the power-off durations of other charging piles from the collection module 5, and then triggers the power supply module 4;

[0027] The power supply module 4, after being triggered, selects to cut off the power supply of at least one of the in-use charging piles according to the power-off duration and the urgent charging duration; within the power-off duration, the charging power of the power-off charging pile is allocated to the target charging pile for urgent charging;

[0028] An information storage module 6, configured to store the power supply durations of users and the remaining values of the power supply durations of each user; the information storage module 6 is connected to the receiving module 1 through an interface.

[0029] In the embodiment of the present application, the power supply load of the community has been designed before the community is built. For the electric vehicle charging part, there are even clear power limitations. For the sake of electrical safety, the charging pile power set by the community is usually relatively low. Therefore, users usually choose to charge at night or during rest. And the night and rest durations are usually much longer than the electric vehicle charging time. For example, if an electric vehicle is expected to be fully charged in 4 to 5 hours, then the night charging duration is at least 3 hours, and the rest time arranged by the user for charging usually also reserves 1 - 2 hours to ensure full charge.

[0030] In this scenario, two problems will arise: on the one hand, the charging power of the community restricts users from charging urgently. For example, sometimes users need to use the car urgently and need to fully charge the battery in 2 hours. However, due to power limitations, users can only fully charge the battery within 4 - 5 hours, so they have to find a high-power charging pile outside the community. On the other hand, users have a lot of ineffective charging time. For example, a user arrives home at 7 pm and starts charging, and drives away at 7 am the next morning. The actual charging time of the user is 12 hours. If the charging power is 10 kW, the vehicle only needs 4 - 5 hours to be fully charged, and the remaining 7 - 8 hours are ineffective charging time.

[0031] In response to the above problems, the present application proposes a contribution charging duration mechanism, which can not only effectively utilize the ineffective charging time but also solve the power limitation.

[0032] Specifically, users need to, according to their actual charging situation, choose to cede a part of their charging time within a certain period. For example, user A finds that their effective charging time per day is 4 hours, which means that as long as they ensure charging for 5 hours during the 7 hours at night, they can fully charge the battery. And in the remaining 2 hours, even if the power is cut off, it will not affect their charging. Then user A can cede these 2 hours as the power-off duration. That is, the user can transfer the power during these 2 hours to the target charging pile. In this way, the target charging pile can charge at twice the original power during these 2 hours, and its charging time can be shortened by 50%. At the same time, this method will not increase the electricity consumption burden. For example, normally, the charging powers of charging piles A, B, and C in the community are set at 10 kW respectively. Now charging pile A is the target charging pile, and charging pile C cedes the power-off duration. Then during the power-off duration period, the charging power of charging pile A is 20 kW, the charging power of charging pile B is 10 kW, and the charging power of charging pile C is 0 kW. In this way, the total charging load remains unchanged, but the charging time of charging pile A is shortened by 50%, and the ineffective charging time of charging pile C is fully utilized.

[0033] To implement the above mechanism, the present application sets up a collection module 5 for collecting the power-off durations of each charging pile. At the same time, to ensure the fairness of the above mechanism, the receiving module 1 is used not only to receive the urgent charging request information sent by the user but also to judge whether the urgent charging request is qualified according to preset conditions. If it is unqualified, the urgent charging request of the user will be rejected. After determining that it is qualified, the determination module 2 determines the target charging pile and the urgent charging duration required by the user. The acquisition module 3 acquires the power-off durations of other charging piles. Finally, the power supply module 4, according to the power-off duration and the urgent charging duration, selects to cut off the power supply of at least one of the charging piles in use; within the power-off duration, it distributes the charging power of the power-off charging pile to the target charging pile for urgent charging.

[0034] It should be noted that the charging pile in this application is adjustable. For example, the maximum power of the charging pile is 4 times the charging power limited by the community. Then, during normal charging, the charging is still carried out according to the charging power limited by the community. Only during emergency charging, and under the condition of ensuring power safety, the charging power of the target charging pile is preferentially adjusted to an integer multiple of the original charging power to achieve emergency charging.

[0035] Embodiment 2. The charging pile operation device according to Embodiment 1 is characterized in that:

[0036] The receiving module 1 further includes a first judgment module, which is used to determine whether the user who sends the emergency request information has submitted an available power-off duration in the past. If so, the determination module 2 is triggered; otherwise, a rejection message is returned to the user, and the current process ends.

[0037] In the embodiment of the present application, in order to further balance the interests of emergency charging users and normal charging users, before emergency charging, it is determined whether the user has submitted an available power-off duration, so as to prevent someone from always charging urgently but never contributing charging time.

[0038] Embodiment 3. The charging pile operation device according to Embodiment 1 is characterized in that:

[0039] The receiving module 1 further includes a second judgment module, which is used to determine whether the emergency charging duration carried in the emergency request information exceeds the cumulative available power supply duration provided by the user. If not, the determination module 2 is triggered; otherwise, a rejection message is returned to the user, and the current process ends.

[0040] In the embodiment of the present application, in order to further balance the interests of emergency charging users and normal charging users, before emergency charging, it is determined whether the emergency charging duration carried in the emergency request information exceeds the cumulative available power supply duration provided by the user, so as to prevent someone from only contributing the duration once or several times but enjoying the right of emergency charging for a long time. For example, user A has only contributed 1 hour of charging duration, but can enjoy the right of emergency charging indefinitely.

[0041] Embodiment 4. The charging pile operation device according to Embodiment 1 is characterized in that the power supply module 4 is configured as:

[0042] The emergency charging duration comes from at least one of the available power-off durations;

[0043] Based on the emergency charging duration and the at least one available power-off duration, determine the charging piles that need to be powered off and the power-off duration of the charging piles that need to be powered off; and

[0044] Cut off the power supply of the corresponding remaining charging piles according to the charging pile that needs to be powered off and the power-off duration of the charging pile that needs to be powered off, and supply power to the target charging pile.

[0045] In the embodiments of the present application, there are multiple ways to select the charging piles to be powered off and the power-off duration. Specifically:

[0046] Method 1

[0047] Prioritize selecting a charging pile with a power-off duration greater than the emergency charging duration and the smallest difference between the power-off duration and the emergency charging duration.

[0048] Taking twice the charging power as an example, the emergency duration is 2 hours. Currently, there are 2 charging piles with a power-off duration of 1 hour, 1 charging pile with a power-off duration of 2 hours, and 1 charging pile with a power-off duration of 3 hours. For the charging pile with a power-off duration of 1 hour, it needs to be reselected midway. And choosing the charging pile with a power-off duration of 3 hours will increase the probability of switching multiple charging piles. Therefore, finally, the charging pile with a power-off duration of 2 hours is selected to be powered off for 2 hours.

[0049] Method 2

[0050] According to the emergency duration, determine the charging power multiple corresponding to the emergency duration. Then, according to the charging power multiple, select the corresponding charging piles to be powered off. For example, if it takes 4 hours to fully charge under normal circumstances and the emergency duration is 1 hour, then the charging power multiple corresponding to the emergency duration is 4. At this time, 3 charging piles with a power-off duration greater than 1 hour need to be selected, the power supply of these 3 charging piles is cut off for 1 hour, and the power of these 3 charging piles is transferred to the target charging pile.

[0051] Method 3

[0052] According to the emergency duration, determine the charging power multiple corresponding to the emergency duration. Then, according to the charging power multiple and the current power-off duration, select the corresponding charging piles to be powered off. For example, if it takes 5 hours to fully charge under normal circumstances and the emergency duration is 2 hours, then the charging power multiple corresponding to the emergency duration is 2.5. Since it is impossible to transfer 0.5 times the charging power, it is possible to charge at 3 times the charging power for 1 hour and then at 2 times the charging power for 1 hour. At this time, 2 charging piles with a power-off duration greater than 1 hour need to be selected first, the power supply of these 2 charging piles is cut off, and the power of these 2 charging piles is transferred to the target charging pile. Then, preferably, one of the above two charging piles is selected as the charging pile to be powered off in the next hour. If the power-off durations of the above two charging piles are both less than 1 hour, another charging pile is selected as the charging pile to be powered off in the next hour.

[0053] Example 5, refer to the appendix Figure 2, A method for operating a charging pile, characterized in that it uses the charging pile operating device described in any one of Embodiments 1-4, including:

[0054] G1. The receiving module 1 receives the urgent request information sent by the user;

[0055] G2. The determining module 2 determines the target charging pile carried by the urgent request information and the urgent charging duration of the target charging pile;

[0056] G3. The obtaining module 3 obtains the power-off duration of other charging piles;

[0057] G4. The power supply module 4 selects to cut off the power supply of at least one of the charging piles in use according to the urgent charging duration and the power-off duration; and

[0058] G5. The power supply module 4 distributes the charging power of the power-off charging pile to the target charging pile for fast charging within the power-off duration.

[0059] Embodiment 6. The method for operating a charging pile according to Embodiment 5, characterized in that it uses the charging pile operating device described in Embodiment 1, and the method further includes:

[0060] The collection module 5 collects the power-off duration of each charging pile according to a preset period.

[0061] In the embodiments of the present application, considering the moving in and out of users and the adjustment of users' commuting time, it is necessary to collect the power-off duration of users every once in a while to ensure the continuous operation of the contribution charging duration mechanism.

[0062] Embodiment 7. The method for operating a charging pile according to Embodiment 6, characterized in that it uses the charging pile operating device described in Embodiment 2, and after G1, the method further includes:

[0063] The judgment module determines whether the user who sends the urgent request information has submitted the power-off duration within the preset period. If so, continue to execute G2; otherwise, end the current process.

[0064] In the embodiments of the present application, in order to further balance the interests of urgent charging users and normal charging users, it is selected to examine the situation of users' contribution charging duration once every period, so as to prevent users from occupying the urgent charging opportunity too much. For example, user A has only contributed the charging duration of 2 hours once throughout the year, but user A has carried out 1 urgent charging throughout the year. Although the urgent charging duration of user A does not exceed the user's power-off duration, if everyone follows suit, it is likely to result in sufficient power-off duration in the first half of the year, but insufficient power-off duration in the second half of the year. However, if it is counted once every six months, it can ensure sufficient power-off duration throughout the year.

[0065] Example 8. The charging pile operation method according to Example 7, characterized in that it uses the charging pile operation device described in Example 4, and the G4 includes:

[0066] The emergency charging duration comes from at least one of the power-off durations;

[0067] Based on the emergency charging duration and the at least one power-off duration, determine the charging piles that need to be powered off and the power-off duration of the charging piles that need to be powered off; and

[0068] Based on the charging piles that need to be powered off and the power-off duration of the charging piles that need to be powered off, cut off the power supply of the corresponding remaining charging piles and supply power to the target charging pile.

[0069] Example 9. The charging pile operation method according to Example 8, characterized in that the method further includes:

[0070] If the power-off duration is less than the emergency charging duration, prompt the user to purchase part of the emergency charging duration with money or preset points.

[0071] In the embodiments of the present application, in the actual process, there may be a situation where the power-off duration is less than the emergency charging duration. At this time, if the emergency user still wants to charge urgently, they can use cash to purchase part of the emergency charging duration, so as to further meet the needs of users for emergency charging.

[0072] Example 10. The charging pile operation method according to Example 6, characterized in that it uses the charging pile operation device described in Example 3. After G1, the method further includes:

[0073] The receiving module 1 is used to determine whether the emergency charging duration carried in the emergency request information exceeds the cumulative power supply duration provided by the user. If not, trigger the determination module 2; otherwise, return a rejection message to the user and end the current process.
