Referring to fig. 1, fig. 1 is a schematic flow chart of a charging management method according to a preferred embodiment of the invention, the charging management method includes the following steps:

in step S110, a charging request is acquired.

Specifically, for the convenience of user's charging, correspond in the parking area of community and set up battery charging outfit on the parking stall to can charge when the user parks. It can be understood that after the user drives the vehicle into the parking space, the vehicle battery is connected to the charging device through the external charging gun or the charging gun of the charging device when charging is required, and charging is started on the charging device or the charging application program. In this embodiment, all the charging devices are connected to the charging cloud platform, and when a user starts charging on the charging device or the charging application program, the charging cloud platform can obtain the charging request and control the charging device to charge the vehicle.

It can be understood that, in this embodiment, a locking device is further disposed in the charging device, when the charging device starts charging the vehicle, the vehicle and the charging device are locked relatively, the charging cloud platform simultaneously sends a locking password to the charging device or a charging application of a user, and the user must input a correct locking password to unlock the vehicle and the charging device, so as to prevent other users from disconnecting the charging connection between the vehicle and the charging device. It can be understood that after the charging cloud platform starts charging of the charging device, the charging right of the charging device is locked, the state of the charging device is modified from an idle state to an occupied state, and other users cannot reserve the charging device to charge through the charging cloud platform.

In step S120, it is determined whether the charging connection is disconnected.

Specifically, in this embodiment, a disconnection detection device is disposed in the charging device, and is configured to detect whether the vehicle and the charging device are disconnected from each other, where the disconnection detection device includes a disconnection detection circuit, and when the charging device is disconnected from the vehicle battery, the disconnection detection circuit may detect that the vehicle and the charging device are disconnected from each other, and transmit the information to the charging cloud platform. In this embodiment, if it is determined that the charging device is disconnected from the charging connection, step S130 is executed; and if the vehicle and the charging equipment are not disconnected in charging, executing the step S131 to continue charging.

It can be understood that, in this embodiment, since the vehicle and the charging device are in a relatively locked state after the charging connection is initiated, and a corresponding unlocking password must be input, when the vehicle and the charging device are disconnected, it is indicated that the user considers that the charging is required or for other reasons, and actively ends the charging process of the vehicle.

In step S130, it is determined whether a hang-up request is received.

Specifically, after it is detected that the vehicle is disconnected from the charging connection, it indicates that the user disconnects the charging, and it needs to be further determined whether the user needs to perform charging and hang up so as to retain the charging right. It will be appreciated that the user disconnecting the charging may be that the charging is on demand or that it is temporarily necessary to go out to interrupt the charging. If the user needs to go out when the charging is disconnected, the user can judge whether the charging and hanging-up are needed according to the self requirement and the use condition of the charging equipment. It can be understood that, if the charging device is in the charging peak period at present, the charging device is tense, and the user thinks that it is difficult to find an idle charging device for charging after going back out, the user may initiate an on-hook request to continue to lock the charging right of the charging device, so that other users cannot use the charging device in the user on-hook period.

In this embodiment, the hang-up request at least needs to include hang-up period information, such as 9-11 o' clock.

Further, if the on-hook request is received, step S140 is executed; if the on-hook request is not received, step S150 is executed.

In step S140, the total cost is calculated.

Specifically, the user may initiate an on-hook request through the charging device or the charging application program, and after receiving the on-hook request, the charging cloud platform indicates that the current charging of the user is completed and the charging needs to be performed on-hook. Because the user needs to leave the charging equipment, the charging fee charged is paid up firstly; meanwhile, after the user hangs up the charging equipment, other users cannot use the charging equipment, namely the charging authority of the charging equipment is locked, so that certain on-hook cost needs to be paid.

Referring to fig. 2, in the present embodiment, the calculating the total cost further includes the sub-steps of S141-S144:

in sub-step S141, a charge wait request is acquired.

Specifically, due to the limited number of charging devices in the community, when there are many vehicles to be charged in the community, the charging device may not satisfy the charging requests of all vehicles, and at this time, there will be a case where the vehicles cannot be charged immediately and need to be charged for waiting. In the present embodiment, it is necessary to send a charge waiting request through a charging application when the vehicle is waiting for charging, and enter a charge waiting sequence in which the vehicle is arranged to be charged in the order of the charge waiting sequence when an idle charging device occurs. It can be understood that when too many vehicles waiting for charging are available, that is, too many charging waiting requests received by the charging cloud platform, if a user hangs up to occupy the charging device, the charging of the vehicles in the community will be greatly affected. Therefore, when the user requests to hang up, it is necessary to further determine whether or not the user can respond to the user request to hang up, based on the charging wait request.

In sub-step S142, it is determined whether the on-hook request can be responded to based on the charge waiting request.

Specifically, in the present embodiment, when the charge waiting request duty ratio does not exceed the preset ratio, the on-hook request can be responded; when the charge waiting request ratio exceeds a preset ratio, the corresponding on-hook request cannot be carried out. Further, the charge waiting request ratio is a ratio of the number of charge waiting requests to the number of charging devices. In the present embodiment, the preset ratio is 10% of the number of charging devices. After the charging cloud platform obtains the number of the charging requests, the charging request proportion needs to be further calculated, and whether an on-hook request can be responded is judged according to the charging request proportion.

Further, if it is determined that the hang-up request can be responded, the substep S143 is performed; if it is determined that the hang-up request cannot be responded to, substep S144 is performed.

In sub-step S143, the charge fee and the on-hook fee are calculated.

Specifically, since the charging cloud platform determines that the on-hook request can be responded currently, after the charging cloud platform calculates the charging cost, the on-hook cost also needs to be calculated according to the on-hook time period in the user on-hook request.

In this embodiment, the on-hook cost is the product of the actual on-hook rate and the duration of the on-hook period. Further, the actual onhook rate is the sum of the basic onhook rate and the floating rate, and the floating rate is the product of the basic onhook rate and the rate floating rate. And the basic on-hook charge rate is equal to the charge rate of the current charging equipment. For example: the charging power of the current charging equipment is 7KW, the charging rate is 2 yuan/KWH, the charging rate of the charging equipment is 3.5 yuan/hour, and the basic on-hook rate is 3.5 yuan/hour.

It can be understood that, under the condition that the on-hook request can be satisfied, when the usage rate of the charging device is high, the charging requirement is high, at this time, the charging influence of the user initiating the on-hook request on other users is also high, and therefore the on-hook cost is also high correspondingly. Therefore, when the on-hook rate is calculated, the charging cloud platform can further calculate the utilization rate of the current charging equipment and calculate the rate floating proportion according to the utilization rate of the current charging equipment, so that the actual on-hook rate is calculated according to the basic on-hook rate and the rate floating proportion. In this embodiment, when the usage rate of the charging device is 60%, the rate floating rate of the actual on-hook rate is 0, that is, equal to the basic on-hook rate, and when the usage rate of the charging device exceeds 60%, the floating rate of the actual on-hook rate is positively correlated with the usage rate of the charging device. For example: when the utilization rate of the charging equipment is 70%, the upward floating proportion of the actual on-hook rate is 5%; and when the utilization rate of the charging equipment is 80%, the upward floating proportion of the actual on-line rate is 10%.

Therefore, when calculating the on-hook charge, the charging cloud platform needs to obtain the current basic on-hook rate and the charging equipment utilization rate, calculate the actual on-hook rate according to the charging equipment utilization rate, and calculate the on-hook charge according to the actual on-hook rate and the duration of the on-hook time period in the on-hook request.

Further, after the charging cloud platform calculates the charging fee and the hang-up fee, the charging cloud platform sends the charging fee and the hang-up fee to the charging device or a charging application program of the user to inform the user that the fee needs to be paid.

In sub-step S144, the charge fee is calculated.

Specifically, the charging cloud platform judges that the on-hook request cannot be responded currently, and then the charging process of the user vehicle is finished after the user disconnects the charging connection, so that the charging cloud platform calculates the charging cost according to the electric quantity charged by the user vehicle and sends the charging cost to the charging equipment or a charging application program of the user to inform the user that the cost needs to be paid.

In step S150, the charging fee is calculated and the charging authority of the charging device is unlocked.

Specifically, if the charging cloud platform does not receive the on-hook request, it indicates that the user actively interrupts charging connection and does not need to hang up, and at this time, the charging cloud platform calculates charging cost of the user during charging and simultaneously unlocks the charging authority of the charging device, so that other users can charge through the charging device.

In step S160, it is determined whether the total charge is paid.

Specifically, after the charging cloud platform calculates the charging cost and the hang-up cost, the charging cost and the hang-up cost are sent to a user charging application program, and the user can leave the charging device after needing to pay the charging cost and the hang-up cost. It can be understood that if the user considers that the on-hook cost is too high after receiving the charging cost and the on-hook cost, the on-hook request can be readjusted and transmitted to the charging cloud platform, and the charging cloud platform recalculates the on-hook cost after receiving the on-hook request. It can be understood that after receiving the total charge paid by the user, the charging cloud platform needs to compare the total charge with the sent total charge, and when the sum of the total charge paid by the user is consistent with the total charging sum sent by the charging cloud platform, it is determined that the user pays the total charge; and when the sum of the total fee paid by the user is inconsistent with the total charging sum sent by the charging cloud platform, judging that the user does not pay the total fee.

In this embodiment, after the user pays the total fee, step S170 is executed; if the user does not pay the total fee, step S171 is executed.

In step S170, the charging authority of the charging device is locked and the reserved charging identifier is stored.

Specifically, when the charging cloud platform receives the total cost paid by the user, the charging cloud platform locks the charging authority of the charging device for the user in the on-hook time period, and meanwhile, the charging cloud platform needs to store a charging identifier for the vehicle so that the user can restore charging after the on-hook time period is finished.

It is understood that the charging identification is used to identify the identity information of the vehicle when the vehicle resumes charging. In this embodiment, the charging identifier may be at least one of a vehicle battery code, a two-dimensional code, or a verification code. The vehicle battery code is an identification code unique to the battery, after the vehicle is in charging connection with the charging equipment, the battery of the vehicle can be communicated with the charging equipment, the battery code of the vehicle is sent to the charging cloud platform through the charging equipment, and the charging cloud platform can store the vehicle battery code of the vehicle as a charging identification for identifying the vehicle after a user initiates an on-hook request. In other embodiments, after receiving an on-hook request from a user, the charging cloud platform may generate and store a two-dimensional code or a verification code as the charging identifier, and send the two-dimensional code or the verification code to a charging application program of the user.

In step S171, the charging authority is unlocked.

Specifically, if the total charge only includes the charging charge, the user can leave the charging device only by paying the charging charge. At this moment, the charging cloud platform unlocks the charging authority of the charging equipment after receiving the total cost paid by the user, and other users can use the charging equipment for charging. Further, if the user does not pay the total fee within the preset time, the user is further marked as an arrearage state by the charging cloud platform, and the charging device can be used after the charging arrearage before the charging device is required to be paid off next time.

Further, if the total charge comprises charging charge and hang-up charge, but a user does not pay the hang-up charge in the total charge within a preset time, the charging cloud platform does not start the hang-up of the charging equipment and unlock the charging authority of the charging equipment; if the user does not pay the charging fee in the total fee within the preset time, the charging cloud platform does not start the charging equipment to hang up and unlock the charging authority of the charging equipment, and meanwhile, the user is marked to be in an arrearage state, and the arrearage amount is the charging fee in the total fee.

In step S180, it is determined whether a reserved charging flag is received during the on-hook period.

Specifically, after the charging cloud platform starts the hang-up of the charging device, it is continuously detected whether the reserved charging identifier is received from the start of the hang-up. It can be understood that the user can return the charging device initiating the on-hook request at any time in the on-hook time period and resume charging, so that if the user returns the charging device in the on-hook time period, the received charging identifier needs to be input, and after receiving the charging identifier, the charging cloud platform first determines whether the charging identifier is in the on-hook time period, and then further checks the charging identifier with the reserved charging identifier stored in the charging cloud platform, so as to determine whether the charging identifier is the reserved charging identifier. It can be understood that the charging cloud platform determines that the reserved charging identifier is received in the on-hook time period only when the time when the charging identifier is received by the charging cloud platform is in the on-hook time period and the charging identifier is consistent with the reserved charging identifier, and then step S190 is executed; when the charging identifier of the user is inconsistent with the charging identifier stored in the charging cloud platform, or the time of receiving the charging identifier is not in the on-hook time period, it is determined that the reserved charging identifier is not received in the on-hook time period, and step S191 is executed.

It can be understood that when the charging identifier is a vehicle battery code, a user only needs to directly connect the vehicle battery with the charging device, and the vehicle battery can send the battery code to the charging device and transmit the battery code to the reserved verification information on the charging cloud platform for comparison; when the charging identifier is a two-dimensional code or a verification code, a user needs to input information of the two-dimensional code or the verification code on the charging device or a charging application program, and the charging cloud platform receives the information and then compares the information with the reserved verification information, so that whether the charging identifier is consistent with the reserved charging identifier is compared.

In step S190, charging is started.

Specifically, after the user presents the charging identifier, the charging cloud platform determines that the time of receiving the charging identifier is within a preset time period and the received charging identifier is a reserved charging identifier, and then it indicates that the vehicle currently initiating the charging request is the vehicle previously initiating the on-hook request. At this time, the charging cloud platform controls the charging device to start charging.

It can be understood that, since the user may return to the charging device at any time within the hang-up period to resume charging, if the user returns to the charging device in advance when the hang-up period is not finished, the actual hang-up period of the user is not consistent with the hang-up period when the hang-up request is initiated, and therefore the charging cloud platform recalculates the hang-up fee according to the actual hang-up period of the user, and returns the difference between the hang-up fee paid by the user and the fee of the actual hang-up period to the account of the charging application program of the user through the charging cloud platform. Further, after the on-hook user resumes charging, the charging cloud platform calculates the charging fee of the user after resuming charging by taking the time of resuming charging of the vehicle as the starting time.

In step S191, charging is not started.

Specifically, in the on-hook period, when other non-on-hook users use the charging device in the on-hook state, the charging identifier also needs to be input, and since the charging identifier, the charging device and the vehicle of the user initiating the on-hook request are uniquely corresponding, the charging identifier input by the other users is not consistent with the charging identifier of the charging device stored by the charging cloud platform, and the charging cloud platform controls the charging device not to start charging. It can be understood that the charging cloud platform controls the charging equipment not to start charging, and at the same time, controls the charging equipment to send out alarm information to remind a customer that the vehicle is in an on-hook state.

It can be understood that if the charging cloud platform does not receive any charging identifier sent by the user in the preset time period, it indicates that the user does not return to the on-hook vehicle for charging in the preset time period. At this moment, the charging cloud platform sends information to the charging application program of the user to remind the user of the end of the on-hook time of the charging equipment, if the on-hook time is not prolonged, the charging authority of the charging equipment is removed, the authority of charging recovery is not reserved for the user any more, namely, the reserved charging identifier is not detected in the on-hook time period, and the charging authority of the charging equipment is unlocked after the on-hook time period is ended.

The present invention further provides a computer device, where the user device includes: a memory, a processor and a program stored on the memory and operable to execute the charge management method on the processor, the processor executing the computer program to cause the computer device to execute the charge management method.

The present invention also proposes a storage medium having stored thereon the program of the charging management method, which when executed by a processor implements the steps of the charging management method as described above. The charging management method can refer to the above embodiments, and is not described herein again.

The charging management method can judge whether to respond to the on-hook request of the user according to the use condition of the charging equipment when the charging equipment is in use shortage, calculates the charging cost and the on-hook cost when the on-hook request of the user can be corresponded, reserves the charging authority of the charging equipment for the user in the on-hook time period after the user pays the corresponding cost, and judges whether the user returns to start charging after the on-hook time period is over, thereby realizing the charging flexibility and meeting the charging requirements of different users.
