Referring to fig. 1, fig. 1 is a schematic flow chart of a charging regulation method according to a preferred embodiment of the present invention, the charging regulation method including the following steps:
in step S110, the numbers of the first charging right user and the second charging right user are acquired.
Specifically, for the convenience of user's charging, can correspond in the community parking area and set up battery charging outfit on partial parking stall to can charge when the user parks. In this embodiment, in order to facilitate the user to control the charging device, a charging application may be provided, and the user may directly start the charging device to charge the user vehicle through the charging application or the charging device. Furthermore, the charging device or the charging application program is connected to a charging cloud platform to upload information to the charging cloud platform or receive an instruction issued by the charging cloud platform. It can be understood that, because the charging requirements of users are different, the users can select corresponding charging modes, such as fast charging, slow charging, etc., as required before starting charging. In this embodiment, the fast charging mode corresponds to the first charging right, and the slow charging mode corresponds to the second charging right. After a user selects a charging mode on charging equipment or a charging application program, the charging equipment or the charging application program uploads charging authority corresponding to the charging mode selected by the user to the charging cloud platform, and the charging cloud platform can control the charging equipment to start charging after recording the charging authority of the user.
Further, in the present embodiment, since the community charging device and the community residential electricity utilization device jointly occupy the community electric power load, in order not to affect the community residential electricity utilization, the charging power of the community charging device sets an upper limit value in advance according to the residential electricity utilization loads of different communities, and the electric power load of the charging device must not exceed the upper limit value so as to avoid affecting the residential electricity utilization. It is understood that, since the charging power of different communities has an upper limit value, the total charging current a of the charging devices in the community also has an upper limit value, and the total charging current a of all the charging devices must not exceed the upper limit value.
Further, the user selects a fast charging mode or a slow charging mode so as to have a first charging authority or a second charging authority, and therefore after receiving the charging authority of the user, the charging cloud platform needs to perform charging regulation and control according to the charging authority of the user, namely the current charging condition. It can be understood that, in this embodiment, the charging cloud platform preferentially ensures that the first charging right user charges with a larger current, and allocates the charging current value of the second charging right user to the first charging right user when the charging current of the first charging right user is insufficient. Correspondingly, the charging rate of the first charging authority user is higher, and the charging rate of the second charging authority user is lower.
Further, the maximum charging current a is allowed due to the charging deviceMAXThe charging current is relatively fixed, for example, 16A, 20A, etc., so that in order to guarantee the charging requirement of the first charging authority user, it is preferentially guaranteed that the first charging authority user adopts the maximum charging current allowed by the charging device for charging. In addition, because the charging current of the first charging authority user is large, and the total charging current a of the community has an upper limit value, if all the devices in the community are charged by using the maximum charging current at the same time, the number of charging devices which can be used at the same time is small, and the charging requirements of the users are difficult to meet. Therefore, in the present embodiment, only a part of the total charging current a is reserved for the first charging right user to ensure the requirement of the first charging right user for fast charging, and the other part of the total charging current a is reserved for the second charging right user to ensure that users with different charging requirements can all charge. In this embodiment, the reserved charging current of the first charging right user is a1The reserved charging current of the second charging authority user is A-A1. It can be understood that, during the charging peak period, the reserved charging current A of the first charging authority user1Used for meeting the charging requirement of a first charging authority user and the reserved charging current A-A of a second charging authority user1Charging for users satisfying a second charging rightA demand; in the charging peak period, when more users are in the first charging authority, the first reserved charging current A1When the charging requirement of the first charging authority user is not met, charging regulation and control are performed, and in the embodiment, the charging regulation and control mode is that the reserved charging current of the second charging authority user is transferred to the first charging authority user.
Further, the reserved charging current A of the user is due to the first charging authority1The maximum charging current A allowed by the charging equipment is relatively fixed due to the fact that the maximum charging current A needs to be set in the charging cloud platform in advanceMAXThus reserving the charging current A1Can only support a first preset number of users with a maximum charging current AMAXAnd charging is carried out. In this embodiment, the first preset number is N1MAXSaid N is1MAX＝A1/AMAX。
Further, when the number of first charging right users is large and exceeds the first preset number, the reserved charging current of the first charging right users is A1It cannot satisfy that all the first charging authority users adopt the maximum charging current AMAXThe charging requirement is met, and the charging current of the second charging authority user needs to be regulated and controlled so as to guarantee the charging requirement of the first charging authority user.
Further, before charging regulation and control are performed, the number of the first charging permission users and the number of the second charging permission users need to be acquired, so that whether charging regulation and control are needed or not is judged conveniently. Specifically, when charging is started, the charging cloud platform can record the number of users using a first charging right and the number of users using a second charging right, so that the charging cloud platform can directly acquire the number of users using the first charging right and the number of users using the second charging right.
In step S120, it is determined whether the number of first charging right users is greater than a first preset number.
Specifically, the charging cloud platform obtains the number N of first charging authority users1And then, whether charging regulation and control are needed is further judged according to the number of the current first charging authority users. When the charging cloud platform obtains the number N of first charging authority users1Then further compare N1Whether or not it is greater than N1MAX. Further, when N is1Not more than N1MAXWhen the charging current is larger than the maximum charging current A, the charging cloud platform can support all the first charging authority users to use the maximum charging current AMAXCharging is carried out, so that charging regulation and control are not needed, and at this time, step S130 is executed to charge the first charging authority user according to the maximum charging current; otherwise, N1Greater than N1MAXWhen the charging current A is larger than the maximum charging current A, the charging cloud platform can not support all the first charging authority users to use the maximum charging current AMAXAnd (5) performing charging, wherein charging regulation is required, and at this time, executing step S140.
In step S140, theoretical charging currents of the first charging authority user and the second charging authority user are calculated.
Specifically, if the reserved charging current of the first charging right user cannot support the current first charging right user to follow the maximum charging current aMAXAnd when charging is carried out, further calculating theoretical charging currents of the first charging authority user and the second charging authority user, and further judging whether the first charging authority user and the second charging authority user meet charging regulation and control conditions.
In this embodiment, the theoretical charging current is an average charging current at which the reserved current of the first charging right user can simultaneously support charging of all first charging right users, and the reserved current of the second charging right user can simultaneously support charging of all second charging right users.
Further, the reserved charging current of the first charging authority user is A1The number of the first charging authority users is N1Therefore, the theoretical charging current of the first charging authority user is A1/N1. For example: the reserved charging current of the first charging authority user is 50A, and the first charging authority userIs 10, the theoretical charging current of the first charging authority user is 50A/10-5A.
Further, the maximum charging current allowed by the charging equipment is AMAXTherefore, when the number of the second charging authority users is not greater than the second preset number, all the second charging authority users can use the maximum charging current AMAXAnd charging is carried out. Further, the second preset number is (A-A)1)/AMAX. It can be understood that when the number of the second charging right users is not greater than the second preset number, the theoretical charging currents of the second charging right users are all aMAX(ii) a Otherwise, when the number of the second charging right users is greater than the second preset number, it indicates that the theoretical charging current of the second charging right users cannot support all the second charging right users to adopt the maximum charging current aMAXCharging is carried out, and the theoretical charging current of the second charging authority user is (A-A)1)/N2. For example: the total charging current is 150A, the reserved charging current of the first charging right user is 50A, the number of the second charging right users is 40, and the theoretical charging current of the second charging right user is (150A-50A)/40 ═ 2.5A.
In step S150, it is determined whether the theoretical charging current ratio between the second charging right user and the first charging right user is smaller than the correlation coefficient.
Specifically, after the current theoretical charging currents of the first charging right user and the second charging right user are calculated, it is further determined whether a ratio of the theoretical charging current of the second charging right user to the theoretical charging current of the first charging right user is greater than a preset correlation coefficient of the system. In this embodiment, the correlation coefficient C is 0.5, and is used to determine whether the current charging situation can be controlled for charging. In this embodiment, when the ratio is not less than C, it indicates that the charge control is possible. Further, when the ratio is not greater than C, it indicates that the theoretical charging current of the first charging authority user does not reach the maximum charging current aMAXTheory of users with second charge authorityThe charging current is relatively small, and at the moment, if the charging regulation and control is carried out, the charging current of the second charging authority user is further reduced, the charging efficiency of the second charging authority user is influenced, and certain influence is brought to the second charging authority user. Therefore, in order to ensure that the second charging right user can also perform normal charging, the charging currents of the first charging right user and the second charging right user cannot be regulated, that is, step S160 is executed to charge the first charging right user and the second charging right user according to the theoretical charging current; on the contrary, when the ratio is larger than C, the theoretical charging current of the first charging authority user is not up to the maximum charging current AMAXMoreover, the theoretical charging current of the second charging right user is relatively high, and there is a certain regulation and control space, and the purpose of increasing the charging current of the first charging right user can be achieved by regulating and controlling part of the charging current of the second charging right user, that is, step S170 is executed.
In step S170, the actual charging currents of the first charging right user and the second charging right user are calculated and regulated.
Specifically, when the charging currents of the first charging right user and the second charging right user are regulated, the actual charging currents of the first charging right user and the second charging right user need to be calculated first, and then the charging currents are regulated and controlled for the first charging right user and the second charging right user according to the calculated actual charging currents. In this embodiment, when calculating the actual charging current, it is necessary to calculate the current adjustment value first, and then calculate the actual charging current according to the current adjustment value. The current adjustment value is the current adjustment value of all the second charging authority users, namely the current adjustment value of the first charging authority user. The actual charging current of the first charging authority user is the sum of the theoretical charging current of the first charging authority user and the first average current adjustment value, and the actual charging current of the second charging authority user is the difference between the theoretical charging current of the second charging authority user and the second average current adjustment value. In this embodiment, the first average current adjustment value is a current adjustment value divided by the number of users with first charging authority; the second average current adjustment value is the current adjustment value divided by the number of users with the second charging authority.
In the present embodiment, the step S170 further includes sub-steps S171 to S173.
In sub-step S171, a first current adjustment value and a second current adjustment value are calculated.
Specifically, when it is determined that the theoretical charging current of the second charging right user can meet the charging regulation requirement, the current adjustment value needs to be calculated according to the correlation coefficient. In this embodiment, there are two optional ways for the adjustment and control, the first way is to adjust the charging current of all the first charging right users to the maximum charging current aMAXThe second way is to allocate all the adjustable currents of all the second charging right users to the first charging right users. In the embodiment, the charging regulation and control is performed according to a first current regulation value in the first regulation and control mode; and the second regulation and control mode carries out charging regulation and control according to a second current regulation value.
Further, in this embodiment, when the control is performed according to the first control method, if the charging currents of all the first charging authority users are adjusted to the maximum charging current aMAXIf the required first current adjustment value exceeds the current that can be regulated and controlled by the second charging authority user, the charging current of all the first charging authority users cannot be adjusted to the maximum charging current AMAX(ii) a In addition, if the second current adjustment value regulated and controlled by the second charging authority user is directly distributed to all the first charging authority users, the actual charging current of the first charging authority users exceeds the maximum charging current AMAXSince the maximum charging current allowed by the charging device is AMAXThen the first charging authority user can only use the maximum charging current AMAXAnd charging is carried out, and the second current adjustment value cannot be directly added to the first charging authority user. Therefore, it is necessary to calculate the first current adjustment value and the second current adjustment value respectively, and further determine which manner is adopted for the charging regulation.
Further, in this embodiment, the first current adjustment value is aMAX*N1-A1Wherein A isMAXMaximum charging current allowed for charging equipment, N1Is the number of first charge authority users, A1And reserving charging current for the first charging authority user. For example: a. theMAXIs 20A, N1Is 5, A1And 50A, the first current adjustment value is 20A by 5-50A to 50A.
Further, the second current adjustment value is A-A1-A1*N2*C/N1Wherein A is charging current, A1Reserve current for a first charge-authorized user, N1Number of users of first charge authority, N2C is a correlation coefficient, and is the number of users having the second charge right. For example: a is 200A, A1Is 50A, N1When N2 is 10 and C is 0.5, the second current adjustment value is 200A-50A 10 0.5/5-100A.
In sub-step S172, the first current adjustment value and the second current adjustment value are compared.
Specifically, after the first current adjustment value and the second current adjustment value are calculated, the first current adjustment value and the second current adjustment value need to be further compared in magnitude to determine the current adjustment value. In this embodiment, the current adjustment value is the smaller of the first current adjustment value or the second current adjustment value.
Further, if the first current adjustment value is not greater than the second current adjustment value, if the charging regulation is performed according to the second current adjustment value, the charging current of the first charging right user after the regulation will be greater than the maximum charging current aMAXTherefore, the charging regulation and control cannot be performed according to the second current regulation value, and the charging regulation and control can be performed only according to the first current regulation value, namely, the current regulation value is the first current regulation value; on the contrary, if the first current adjustment value is greater than the second current adjustment value, it indicates that the actual charging current of the first charging right user cannot reach the maximum charging current a after the charging regulation is performed according to the second current adjustment valueMAXTherefore, if the current is regulated according to the first current regulation value, the adjustable current of the second charging authority user cannot meet the requirementThe regulation and control requirement of the first current regulation value can only carry out charging regulation and control according to the second current regulation value, namely the current regulation value is the second current regulation value.
As described above, if the first current adjustment value is 50A and the second current adjustment value is 100A, the first current adjustment value is smaller than the second current adjustment value.
In sub-step S173, the actual charging currents of the first and second charging authority users are calculated according to the first or second current adjustment value.
Specifically, after comparing the first current adjustment value with the second current adjustment value, the charging cloud platform can obtain the current adjustment value, and calculate and regulate actual charging currents of the first charging authority user and the second charging authority user according to the current adjustment value.
Further, when the charging regulation is performed according to the first current regulation value, the first current regulation value is AMAX*N1-A1If the actual charging current of the first charging authority user is AMAXThe actual charging current of the second charging authority user is (A-A)MAX*N1)/N2Wherein A is the total charging current, AMAXTo the maximum allowable charging current, A1Charging current reserved for a first charging authority user, N1Number of users of first charge authority, N2The number of users of the second charge authority. For example: a is 200A, AMAXIs 20A, N1Is 8, N2Is 30, A1If the charging current is 50A, the theoretical charging current of the first charging authority user is 50A/8-6.25A, and the actual charging current is 20A; the theoretical charging current of the second charging authority user is (200A-50A)/30 ═ 5A, and the actual charging current is (200A-20A × (8)/30 ═ 1.33A. As can be seen from the above, by the above charging regulation and control method, the actual charging current of the first charging authority user can be regulated to 20A, and the actual charging current of the second charging authority user can be regulated to 1.33A.
Furthermore, when the charging regulation is carried out according to a second current regulation value, the second current regulation value is A-A1-A1*N2*C/N1Then, the actual charging current of the first charging authority user is (a × N)1-A1*N2*C)/N1 2The actual charging current of the second charging authority user is A1/N1C, wherein A is the total charging current, A1Charging current reserved for a first charging authority user, N1Number of users of first charge authority, N2C is a correlation coefficient, and is the number of users having the second charge right. For example: a is 200A, A1Is 50A, N1Is 10, N2And 20, the theoretical charging current of the first charging authority user is 50A/5-10A, and the actual charging current is (200A 10-50A 20 0.5)/10215A; the theoretical charging current of the second charging authority user is (200A-50A)/20 ═ 7.5A, and the actual charging current is 50A/10 ×, 0.5 ═ 2.5A. Therefore, by the charging regulation and control method, the actual charging current of the first charging authority user can be regulated to 15A, and the actual charging current of the second charging authority user can be regulated to 2.5A.
Therefore, through the calculation, the actual charging current of the first charging authority user can be increased and the actual charging current of the second charging authority user can be reduced according to the charging regulation and control of the first current regulation value and the second current regulation value, and the charging requirement of the first charging authority user is met.
In sub-step S174, the users with the first and second charging authorities are charged according to the actual charging current.
Specifically, after the charging cloud platform calculates the actual charging currents of a first charging authority user and a second charging authority user respectively, the actual charging currents are sent to the charging device, and the vehicles of the users are charged according to the actual charging currents.
It can be understood that after each new first charging authority user is accessed into the charging cloud platform, whether charging regulation and control are needed or not is judged again, and actual charging current is calculated when charging regulation and control are needed, so that the first charging authority user can obtain relatively large charging current, and quick charging can be achieved.
