Description

充电系统、充电方法、计算机设备及存储介质Charging system, charging method, computer equipment and storage medium 技术领域Technical field
本发明涉及智慧充电领域，具体而言，主要涉及一种提高充电效率的充电系统、充电方法、计算机设备及存储介质。The present invention relates to the field of smart charging, and in particular, it mainly relates to a charging system, a charging method, a computer device and a storage medium that improve charging efficiency.
背景技术Background technique
随着科技水平和人们生活水平的不断提高，越来越多的人开始购买车辆来提升生活的便利性，改善生活质量。但是由于目前车辆容量的不断增多，车辆尾气的排放给生态环境带来了较大影响。为了改善日益恶化的生态环境，电动汽车应运而生，电动汽车通过电力驱动车辆行驶，在行驶过程中不会产生车辆尾气，对减少车辆尾气和改善环境污染具有较大作用。With the continuous improvement of the level of technology and people's living standards, more and more people are beginning to buy vehicles to enhance the convenience of life and improve the quality of life. However, due to the current increase in vehicle capacity, vehicle exhaust emissions have brought a greater impact on the ecological environment. In order to improve the deteriorating ecological environment, electric vehicles came into being. Electric vehicles drive vehicles by electric power and will not produce vehicle exhaust during driving, which has a greater effect on reducing vehicle exhaust and improving environmental pollution.
技术问题technical problem
目前车辆的电池容量普遍较低，续航较短，需要频繁地使用充电桩来充电从而保证车辆的使用。为了保证多个用户同时充电的需求，在部分充电桩上会设置两个甚至多个充电枪来同时为车辆进行充电，以保证用户的充电需求。目前多枪充电的方式中，充电桩仅会根据不同车辆的充电需求，即车辆的需求充电电流为车辆进行充电，由于不同的车辆在充电时的效率不同，若仅根据车辆的充电需求来为车辆充电，则会存在部分车辆充电效率较低，但是需求充电电流又较大的情况，因此若直接按照需求充电电流为车辆充电，则会带来较多的电能浪费，将会导致充电系统的整体充电效率较低，造成了较大的损失。因此如何提供一种高效率的多枪充电系统将成为充电行业发展的一个重要课题。At present, the battery capacity of vehicles is generally low, and the battery life is short. It is necessary to frequently use charging piles for charging to ensure the use of the vehicle. In order to ensure that multiple users need to charge at the same time, two or more charging guns will be installed on some charging piles to charge the vehicle at the same time to ensure the user's charging needs. In the current multi-gun charging method, the charging pile will only charge the vehicle according to the charging requirements of different vehicles, that is, the required charging current of the vehicle. Since different vehicles have different charging efficiency, if only according to the charging requirements of the vehicle, For vehicle charging, some vehicles have low charging efficiency, but the required charging current is relatively large. Therefore, if the vehicle is charged directly according to the required charging current, it will cause more electric energy waste, which will lead to the charging system. The overall charging efficiency is low, causing a greater loss. Therefore, how to provide a high-efficiency multi-gun charging system will become an important issue for the development of the charging industry.

进一步地，所述处理单元20进一步根据所述通信单元40获取的所述新接入车辆的充电功率、所述已接入车辆的充电功率及充电系统的输出功率计算所述充电系统的充电效率，并从所述充电效率中得出所述充电系统的最大充电效率；所述调控单元30进一步在所述处理单元20得出所述最大充电效率后根据所述最大充电效率对应的充电电流控制所述新接入车辆和所述已接入车辆进行充电。Further, the processing unit 20 further calculates the charging efficiency of the charging system according to the charging power of the newly connected vehicle, the charging power of the connected vehicle, and the output power of the charging system obtained by the communication unit 40 , And obtain the maximum charging efficiency of the charging system from the charging efficiency; the control unit 30 further controls the charging current according to the maximum charging efficiency after the processing unit 20 obtains the maximum charging efficiency The newly connected vehicle and the connected vehicle are charged.
进一步地，在本实施方式中，车辆在使用所述充电系统100进行充电时，需要将所述充电系统100上的一个充电枪与所述车辆的充电接口连接并通过扫码或刷卡的方式启动充电，当用户将充电枪与车辆连接并启动充电后，所述车辆即为新接入车辆，所述充电需求获取单元10即可获取到所述新接入车辆的充电需求。进一步地，在本实施方式中，所述充电需求中至少需包括所述新接入车辆的需求充电电流，所述需求充电电流为所述车辆的电池能够承受的最大充电电流。Further, in this embodiment, when a vehicle uses the charging system 100 for charging, it is necessary to connect a charging gun on the charging system 100 to the charging interface of the vehicle and start it by scanning a code or swiping a card. For charging, when the user connects the charging gun to the vehicle and starts charging, the vehicle is a newly connected vehicle, and the charging demand acquisition unit 10 can obtain the charging demand of the newly connected vehicle. Further, in this embodiment, the charging demand needs to include at least the required charging current of the newly connected vehicle, and the required charging current is the maximum charging current that the battery of the vehicle can withstand.
进一步地，当接收到所述新接入车辆的充电需求后，所述处理单元20需要根据所述充电需求中的需求充电电流得出所述新接入车辆的拟充电电流。进一步地，在本实施方式中，由于所述充电系统100具有至少两个充电枪，所述至少两个充电枪均由所述充电系统100进行电能输出，则所述至少两个充电枪的充电电流不应超过所述充电系统100的最大输出电流，由于所述充电系统100的可用充电电流等于所述充电系统100的最大输出电流与使用中的充电电流的差值，因此新接入充电系统连接的充电枪的充电电流不应超过所述充电系统100的可用充电电流。可以理解，由于不同充电枪的规格不同，因此不同的充电枪也具有相应的最大充电电流，所述充电枪的输出电流也不应超过所述充电枪的最大充电电流。因此，在本实施方式中，根据充电枪的最大充电电流和所述充电系统100的可用充电电流为每一充电枪设置限制充电电流，所述新接入车辆连接充电枪进行充电时的拟充电电流不得超过所述车辆连接的充电枪的限制充电电流，从而防止由于电流过大造成充电枪或充电系统100损坏。进一步地，计算所述新接入车辆连接的充电枪的限制充电电流时，需要先获取充电系统100使用中的充电电流，即所述充电系统100已接入车辆的充电电流之和，并计算所述充电系统100的可用充电电流，再根据所述新接入车辆连接的充电枪的最大充电电流从而得出所述充电枪的限制充电电流。Further, after receiving the charging demand of the newly connected vehicle, the processing unit 20 needs to obtain the intended charging current of the newly connected vehicle according to the required charging current in the charging demand. Further, in this embodiment, since the charging system 100 has at least two charging guns, and the at least two charging guns are all outputted by the charging system 100, the charging of the at least two charging guns The current should not exceed the maximum output current of the charging system 100. Since the available charging current of the charging system 100 is equal to the difference between the maximum output current of the charging system 100 and the charging current in use, a new charging system is connected The charging current of the connected charging gun should not exceed the available charging current of the charging system 100. It can be understood that because different charging guns have different specifications, different charging guns also have corresponding maximum charging currents, and the output current of the charging guns should not exceed the maximum charging current of the charging guns. Therefore, in this embodiment, the charging current limit is set for each charging gun according to the maximum charging current of the charging gun and the available charging current of the charging system 100, and the proposed charging when the newly connected vehicle is connected to the charging gun for charging The current must not exceed the limited charging current of the charging gun connected to the vehicle, thereby preventing damage to the charging gun or the charging system 100 due to excessive current. Further, when calculating the limited charging current of the charging gun connected to the newly connected vehicle, it is necessary to first obtain the charging current in use of the charging system 100, that is, the sum of the charging currents of the vehicle connected to the charging system 100, and calculate The available charging current of the charging system 100 is then based on the maximum charging current of the charging gun connected to the newly connected vehicle to obtain the limited charging current of the charging gun.
进一步地，所述处理单元20计算出所述新接入车辆连接的充电枪的限制充电电流后，需要将所述新接入车辆的需求充电电流与所述充电枪的限制充电电流进行比较，从而得出所述新接入车辆的拟充电电流。可以理解，为了充电安全，在充电过程中，充电电流不应大于所述车辆的需求充电电流；进一步地，所述充电电流也不应大于所述充电枪的限制充电电流。因此，所述拟充电电流为所述需求充电电流和所述充电枪的限制充电电流中的较小值。Further, after the processing unit 20 calculates the limited charging current of the charging gun connected to the newly connected vehicle, it needs to compare the required charging current of the newly connected vehicle with the limited charging current of the charging gun, Thus, the proposed charging current of the newly connected vehicle is obtained. It can be understood that, for charging safety, during the charging process, the charging current should not be greater than the required charging current of the vehicle; further, the charging current should not be greater than the limited charging current of the charging gun. Therefore, the pseudo charging current is the smaller value of the required charging current and the limited charging current of the charging gun.
进一步地，在本实施方式中，所述限制充电电流为所述充电系统100的可用充电电流和所述充电枪的最大充电电流中的较小值，所述可用充电电流为所述最大输出电流和使用中的充电电流的差值，所述使用中的充电电流为所述充电系统100已接入车辆的充电电流之和，所述新接入车辆的拟充电电流为所述需求充电电流和所述充电枪的限制充电电流中的较小值。例如：所述充电系统100的最大输出电流为100A，所述充电系统100已接入车辆A和车辆B，其中车辆A的充电电流为30A，车辆B的充电电流为35A，则所述充电系统100的可用充电电流为100A-30A-35A=35A；所述车辆C为新接入车辆，所述车辆C连接的充电枪的最大充电电流为40A，则所述车辆C连接的车辆的限制充电电流为35A，若所述车辆C的需求充电电流为40A，则所述车辆C的拟充电电流为35A；若所述车辆C的需求充电电流为30A，则所述车辆C的拟充电电流为30A。可以理解，由于所述新接入车辆充电的过程中，所述充电系统100将会根据充电效率调整所述新接入车辆的拟充电电流，因此所述拟充电电流不一定为所述新接入车辆的最终的充电电流，仅为所述新接入车辆在充电调控的过程中的过程充电电流。Further, in this embodiment, the limited charging current is the smaller of the available charging current of the charging system 100 and the maximum charging current of the charging gun, and the available charging current is the maximum output current. The difference between the charging current in use and the charging current in use, which is the sum of the charging currents of the charging system 100 that has been connected to the vehicle, and the proposed charging current of the newly connected vehicle is the sum of the required charging currents The charging gun limits the smaller value of the charging current. For example: the maximum output current of the charging system 100 is 100A, the charging system 100 has been connected to vehicle A and vehicle B, where the charging current of vehicle A is 30A, and the charging current of vehicle B is 35A, then the charging system The available charging current of 100 is 100A-30A-35A=35A; the vehicle C is a newly connected vehicle, and the maximum charging current of the charging gun connected to the vehicle C is 40A, then the limited charging of the vehicle connected to the vehicle C The current is 35A. If the required charging current of the vehicle C is 40A, the pseudo charging current of the vehicle C is 35A; if the required charging current of the vehicle C is 30A, the pseudo charging current of the vehicle C is 30A. It can be understood that, since the charging system 100 will adjust the proposed charging current of the newly connected vehicle according to the charging efficiency during the charging process of the newly connected vehicle, the proposed charging current may not necessarily be the newly connected vehicle. The final charging current into the vehicle is only the process charging current of the newly connected vehicle in the charging regulation process.
进一步地，当所述充电系统100中新接入车辆后，由于不同车辆的充电效率不同，为了提高充电系统的充电效率，则需要再次计算并分配所述充电系统100的不同充电枪的充电电流，从而调整充电系统100的已接入车辆的充电电流和新接入车辆的充电电流以使得所述充电系统100的充电效率最大。Further, when the charging system 100 is newly connected to a vehicle, because the charging efficiency of different vehicles is different, in order to improve the charging efficiency of the charging system, it is necessary to calculate and allocate the charging current of different charging guns of the charging system 100 again. Therefore, the charging current of the connected vehicle of the charging system 100 and the charging current of the newly connected vehicle are adjusted to maximize the charging efficiency of the charging system 100.
进一步地，在本实施方式中，所述处理单元20需要根据所述拟充电电流和所述新接入车辆连接的充电枪的限制充电电流计算第一电流调整值或第二电流调整值，并根据所述第一电流调整值或所述第二电流调整值调整所述充电系统100的所述已接入车辆的充电电流和所述新接入车辆的充电电流，再计算调整充电电流后的充电系统的充电效率，从而使得充电效率最大化。Further, in this embodiment, the processing unit 20 needs to calculate the first current adjustment value or the second current adjustment value according to the proposed charging current and the limited charging current of the charging gun connected to the newly connected vehicle, and Adjust the charging current of the connected vehicle and the charging current of the newly connected vehicle of the charging system 100 according to the first current adjustment value or the second current adjustment value, and then calculate the adjusted charging current The charging efficiency of the charging system, thereby maximizing the charging efficiency.
进一步地，在本实施方式中，由于所述调控单元30进行充电调控时，需要根据所述第一电流调整值或所述第二电流调整值调升所述新接入车辆的充电电流且调降所述已接入车辆的当前充电电流，因此仅在所述新接入车辆的拟充电电流小于所述新接入车辆连接的充电枪的限制充电电流时，才能够进行充电调控，因此在充电调控前，需要由所述处理单元20比较所述新接入车辆的拟充电电流和所述新接入车辆连接的充电枪的限制充电电流，并根据比较结果计算第一电流调整值或第二电流调整值并由所述调控单元30根据所述第一电流调整值或所述第二电流调整值进行充电调控。Further, in this embodiment, when the control unit 30 performs charging control, it needs to increase the charging current of the newly connected vehicle and adjust it according to the first current adjustment value or the second current adjustment value. The current charging current of the connected vehicle is reduced, so charging control can be performed only when the proposed charging current of the newly connected vehicle is less than the limited charging current of the charging gun connected to the newly connected vehicle. Before charging control, the processing unit 20 needs to compare the proposed charging current of the newly connected vehicle with the limited charging current of the charging gun connected to the newly connected vehicle, and calculate the first current adjustment value or the first current adjustment value according to the comparison result. Two current adjustment values, and the adjustment unit 30 performs charging adjustment according to the first current adjustment value or the second current adjustment value.
进一步地，在本实施方式中，所述调控单元30在进行充电调控的过程中，所述新接入车辆的拟充电电流不得大于所述新接入车辆连接的充电枪的限制充电电流，否则将会导致车辆或充电系统100损坏。因此，在调控的过程中需要判断所述拟充电电流与充电枪的限制充电电流的关系，以防止在调控时导致所述新接入车辆的拟充电电流超过所述新接入车辆连接的充电枪的限制充电电流的情况。进一步地，若所述新接入车辆的拟充电电流调升所述第一电流调整值后，不会超过所述限制充电电流，则按照所述第一电流调整值进行调控；若所述新接入车辆的拟充电电流调升所述第一电流调整值后，会超过所述限制充电电流，将按照所述第二电流调整值进行调控；若所述新接入车辆的拟充电电流等于所述限制充电电流，则不需要再进行充电调控，否则调控后所述拟充电电流将会超过所述限制充电电流，从而带来安全隐患。Further, in this embodiment, during the charging control process of the control unit 30, the proposed charging current of the newly connected vehicle shall not be greater than the limited charging current of the charging gun connected to the newly connected vehicle, otherwise It will cause damage to the vehicle or the charging system 100. Therefore, it is necessary to determine the relationship between the proposed charging current and the limited charging current of the charging gun during the adjustment process, so as to prevent the proposed charging current of the newly connected vehicle from exceeding the charging current of the newly connected vehicle during the adjustment. The gun’s limited charging current situation. Further, if the proposed charging current of the newly connected vehicle does not exceed the limited charging current after the first current adjustment value is increased, then the adjustment is performed according to the first current adjustment value; if the new After the pseudo charging current of the connected vehicle is increased by the first current adjustment value, it will exceed the limited charging current and will be regulated according to the second current adjustment value; if the pseudo charging current of the newly connected vehicle is equal to The limited charging current does not need to be adjusted for charging, otherwise the pseudo-charging current after the adjustment will exceed the limited charging current, which may cause safety hazards.
进一步地，在本实施方式中，所述处理单元20在所述新接入车辆的拟充电电流小于所述新接入车辆连接的充电枪的限制充电电流时，计算所述第一电流调整值。可以理解，在本实施方式中，为了保证电流调整的精度和效率，所述第一电流调整值与所述新接入车辆的拟充电电流和所述充电枪的最大充电电流相关，即所述新接入车辆的拟充电电流和所述充电枪的最大充电电流较低时，所述第一电流调整值相对较低；所述新接入车辆的拟充电电流和所述充电枪的最大充电电流较大时，所述第一电流调整值相对较高，从而保证电流调控的效率和精度。进一步地，所述处理单元20在所述拟充电电流小于所述新接入车辆连接的充电枪的限制充电电流且所述新接入车辆连接的充电枪的限制充电电流不大于第一预设值时，得出所述第一电流调整值为所述第一预设值与预设系数的乘积；所述处理单元20在所述拟充电电流大于第一预设值且不大于所述新接入车辆连接的充电枪的限制充电电流且所述新接入车辆连接的充电枪的限制充电电流不大于所述第二预设值时，得出所述第一电流调整值为所述第二预设值与所述预设系数的乘积。进一步地，在本实施方式中，所述第一预设值为6A，所述第二预设值为63A，预设系数为1%。可以理解，所述预设系数越低则所述调控单元40进行充电调控时的幅度越小，所述调控单元40充电调控的次数越多，因此计算出来的所述充电效率的精度和准确度越高。但是，由于所述预设系数较低时，所述调控单元40调控的次数越多，因此可能所需的调控时间将会较长，因此为了保证调控的精度和效率，可根据需要设置所述预设系数，例如将所述预设系数可为5%，10%等。进一步地，例如：当所述新接入车辆连接的充电枪的限制充电电流为5A，所述新接入车辆的拟充电电流为4A时，则所述第一电流调整值为6A*1%=0.06A；当所述新接入车辆连接的充电枪的限制充电电流为32A，所述新接入车辆的拟充电电流为30A，则所述第一电流调整值为63A*1%=0.63A。Further, in this embodiment, the processing unit 20 calculates the first current adjustment value when the proposed charging current of the newly connected vehicle is less than the limited charging current of the charging gun connected to the newly connected vehicle . It can be understood that, in this embodiment, in order to ensure the accuracy and efficiency of current adjustment, the first current adjustment value is related to the proposed charging current of the newly connected vehicle and the maximum charging current of the charging gun, that is, the When the proposed charging current of the newly connected vehicle and the maximum charging current of the charging gun are low, the first current adjustment value is relatively low; the proposed charging current of the newly connected vehicle and the maximum charging current of the charging gun When the current is large, the first current adjustment value is relatively high, thereby ensuring the efficiency and accuracy of current control. Further, the processing unit 20 is configured when the proposed charging current is less than the limited charging current of the charging gun connected to the newly connected vehicle and the limited charging current of the charging gun connected to the newly connected vehicle is not greater than a first preset Value, it is obtained that the first current adjustment value is the product of the first preset value and the preset coefficient; the processing unit 20 when the pseudo charging current is greater than the first preset value and not greater than the new When the limited charging current of the charging gun connected to the connected vehicle and the limited charging current of the charging gun connected to the newly connected vehicle is not greater than the second preset value, it is obtained that the first current adjustment value is the first The product of two preset values and the preset coefficients. Further, in this embodiment, the first preset value is 6A, the second preset value is 63A, and the preset coefficient is 1%. It can be understood that the lower the preset coefficient, the smaller the amplitude when the control unit 40 performs charging control, and the more times the control unit 40 performs charging control, therefore, the accuracy and accuracy of the calculated charging efficiency are Higher. However, since the preset coefficient is lower, the more the adjustment times of the adjustment unit 40, the longer the adjustment time may be required. Therefore, in order to ensure the accuracy and efficiency of the adjustment, the adjustment may be set as required. The preset coefficient, for example, the preset coefficient may be 5%, 10%, etc. Further, for example: when the limited charging current of the charging gun connected to the newly connected vehicle is 5A, and the proposed charging current of the newly connected vehicle is 4A, the first current adjustment value is 6A*1% =0.06A; when the limited charging current of the charging gun connected to the newly connected vehicle is 32A, and the proposed charging current of the newly connected vehicle is 30A, the first current adjustment value is 63A*1%=0.63 A.
进一步地，当计算出所述第一电流调整值后，所述处理单元20需要进一步判断所述拟充电电流能否调升所述第一电流调整值，因此所述处理单元20进一步将所述新接入车辆的拟充电电流与所述第一电流调整值相加来判断是否大于所述限制充电电流。可以理解，若所述接入车辆的拟充电电流与所述第一电流调整值相加大于所述拟充电电流，则说明进行充电调控后所述拟充电电流将会超过所述充电枪的限制充电电流，因此不允许将所述拟充电电流调升所述第一电流调整值，而仅能将所述拟充电电流调升所述第二电流调整值；若所述新接入车辆的拟充电电流与所述第一电流调整值相加不大于所述充电枪的限制充电电流，则说明进行充电调控后所述拟充电电流将不会超过充电枪的所述限制充电电流，因此允许将所述拟充电电流调升所述第一电流调整值。Further, after calculating the first current adjustment value, the processing unit 20 needs to further determine whether the pseudo-charging current can increase the first current adjustment value, so the processing unit 20 further The proposed charging current of the newly connected vehicle is added to the first current adjustment value to determine whether it is greater than the limited charging current. It can be understood that if the sum of the pseudo-charging current of the connected vehicle and the first current adjustment value is greater than the pseudo-charging current, it means that the pseudo-charging current will exceed the limit of the charging gun after the charging control is performed. Charging current, therefore, it is not allowed to increase the proposed charging current by the first current adjustment value, and only the proposed charging current can be increased by the second current adjustment value; if the proposed charging current is newly connected to the vehicle The sum of the charging current and the first current adjustment value is not greater than the limited charging current of the charging gun, which means that the pseudo-charging current will not exceed the limited charging current of the charging gun after the charging adjustment is performed. Therefore, it is allowed to change The proposed charging current increases the first current adjustment value.
因此，在本实施方式中，所述处理单元20用于在所述新接入车辆的拟充电电流与所述第一电流调整值之和不大于所述新接入车辆连接的充电枪的限制充电电流时，需要根据所述第一电流调整值计算第一电流调升目标值及至少一第一电流调降目标值并发送至所述调控单元30以便于所述调控单元30进行充电调控。进一步地，所述调控单元30在接收到所述第一电流调升目标值及所述至少一第一电流调降目标值时根据所述第一电流调升目标值控制所述新接入车辆进行充电，并根据所述至少一第一电流调降目标值分别控制所述已接入车辆进行充电。进一步地，在本实施方式中，所述第一电流调升目标值为所述新接入车辆的拟充电电流与所述第一电流调整值之和，所述第一电流调降目标值为一所述已接入车辆的当前充电电流与第三电流调整值之差，所述第三电流调整值为所述第一电流调整值与所述已接入车辆的数量的比值。例如：所述第一电流调整值为0.63A，所述新接入车辆的拟充电电流为6A，所述新接入车辆为1辆，且当前充电电流为10A，则所述第一电流调升目标值为6A+0.63A=6.63A，所述第三电流调整值为0.63A/1=0.63A，所述第一电流调降目标值为6A-0.63A=5.37A；若所述新接入车辆为2辆，且一辆的当前充电电流为10A，另一辆的当前充电电流为9A，则所述第三电流调整值为0.63A/3=0.21A，由于所述当前接入车辆为两辆，则所述第一电流调降目标值为2个，一个电流调降目标值为10A-0.21A=9.79A，另一个电流调降目标值为9A-0.21A=8.79A。Therefore, in this embodiment, the processing unit 20 is used to determine that the sum of the proposed charging current of the newly connected vehicle and the first current adjustment value is not greater than the limit of the charging gun connected to the newly connected vehicle. When charging current, a first current increase target value and at least one first current decrease target value need to be calculated according to the first current adjustment value and sent to the adjustment unit 30 so that the adjustment unit 30 can perform charging adjustment. Further, when the control unit 30 receives the first current increase target value and the at least one first current increase target value, the newly connected vehicle is controlled according to the first current increase target value. Charging is performed, and the connected vehicles are respectively controlled to be charged according to the at least one first current reduction target value. Further, in this embodiment, the first current increase target value is the sum of the proposed charging current of the newly connected vehicle and the first current adjustment value, and the first current decrease target value is A difference between the current charging current of the connected vehicle and a third current adjustment value, where the third current adjustment value is a ratio of the first current adjustment value to the number of connected vehicles. For example: the first current adjustment value is 0.63A, the proposed charging current of the newly connected vehicle is 6A, the newly connected vehicle is 1 vehicle, and the current charging current is 10A, then the first current adjustment The increase target value is 6A+0.63A=6.63A, the third current adjustment value is 0.63A/1=0.63A, and the first current decrease target value is 6A-0.63A=5.37A; if the new There are two connected vehicles, and the current charging current of one vehicle is 10A, and the current charging current of the other vehicle is 9A, then the third current adjustment value is 0.63A/3=0.21A, because the current access If there are two vehicles, the first current reduction target value is two, one current reduction target value is 10A-0.21A=9.79A, and the other current reduction target value is 9A-0.21A=8.79A.
进一步地，若所述新接入车辆的拟充电电流与所述第一电流调整值之和大于所述新接入车辆连接的充电枪的限制充电电流时，则说明进行充电调控后所述拟充电电流将会超过所述充电枪的限制充电电流，因此不允许将所述拟充电电流调升所述第一电流调整值，此时需要计算所述第二电流调整值，以根据所述第二电流调整值来进行充电调控。进一步地，所述处理单元20用于在所述新接入车辆的拟充电电流与所述第一电流调整值之和大于所述新接入车辆连接的充电枪的限制充电电流时，计算第二电流调整值并根据所述第二电流调整值计算第二电流调升目标值及至少二第一电流调降目标值并发送至所述调控单元30以便于所述调控单元30进行充电调控。进一步地，在本实施方式中，所述第二电流调整值为所述新接入车辆连接的充电枪的限制充电电流与所述新接入车辆的拟充电电流的差值。例如：所述车辆的需求充电电流为30A，所述新接入车辆连接的充电枪的最大充电电流为45A，所述第一电流调整值为0.63A，所述新接入车辆的拟充电电流为29.5A，则所述新接入车辆连接的充电枪的限制充电电流为30A，所述第二电流调整值为30A-29.5A=0.5A。进一步地，在本实施方式中，所述第二电流调升目标值为所述新接入车辆的拟充电电流与所述第二电流调整值之和，所述第二电流调降目标值为一所述已接入车辆的当前充电电流与第四电流调整值之差，所述第四电流调整值为所述第二电流调整值与所述已接入车辆的数量的比值。例如：所述第二电流调整值为0.5A，所述新接入车辆的拟充电电流为8A，所述已接入车辆为1辆，且充电电流为11A，则所述第二电流调升目标值为8A+0.5A=8.5A，所述第四电流调整值为0.5A/1=0.5A，所述第二电流调降目标值为11A-0.5A=10.5A；若所述已接入车辆为2辆，且1辆充电电流为11A，另一辆充电电流为12A，则所述第四电流调整值为0.5A/2=0.25A，则所述第二电流调降目标值为2个，一个电流调降目标值为11A-0.25A=9.75A，另一个电流调降目标值为12A-0.25A=11.75A。Further, if the sum of the proposed charging current of the newly connected vehicle and the first current adjustment value is greater than the limited charging current of the charging gun connected to the newly connected vehicle, it is indicated that the proposed charging current is adjusted after the charging is performed. The charging current will exceed the limit charging current of the charging gun. Therefore, it is not allowed to increase the proposed charging current to the first current adjustment value. At this time, the second current adjustment value needs to be calculated to be based on the first current adjustment value. Two current adjustment values for charging control. Further, the processing unit 20 is configured to calculate the first charging current when the sum of the proposed charging current of the newly connected vehicle and the first current adjustment value is greater than the limited charging current of the charging gun connected to the newly connected vehicle Two current adjustment values, a second current increase target value and at least two first current decrease target values are calculated according to the second current adjustment value and sent to the adjustment unit 30 so that the adjustment unit 30 can perform charging adjustment. Further, in this embodiment, the second current adjustment value is the difference between the limited charging current of the charging gun connected to the newly connected vehicle and the pseudo-charging current of the newly connected vehicle. For example: the required charging current of the vehicle is 30A, the maximum charging current of the charging gun connected to the newly connected vehicle is 45A, the first current adjustment value is 0.63A, and the proposed charging current of the newly connected vehicle If it is 29.5A, the limited charging current of the charging gun connected to the newly connected vehicle is 30A, and the second current adjustment value is 30A-29.5A=0.5A. Further, in this embodiment, the second current increase target value is the sum of the proposed charging current of the newly connected vehicle and the second current adjustment value, and the second current decrease target value is A difference between the current charging current of the connected vehicle and a fourth current adjustment value, where the fourth current adjustment value is a ratio of the second current adjustment value to the number of connected vehicles. For example: the second current adjustment value is 0.5A, the proposed charging current of the newly connected vehicle is 8A, the connected vehicle is 1 vehicle, and the charging current is 11A, then the second current is increased The target value is 8A+0.5A=8.5A, the fourth current adjustment value is 0.5A/1=0.5A, and the second current reduction target value is 11A-0.5A=10.5A; If there are two vehicles entering, and one vehicle has a charging current of 11A, and the other vehicle has a charging current of 12A, the fourth current adjustment value is 0.5A/2=0.25A, and the second current reduction target value is Two, one current reduction target value is 11A-0.25A=9.75A, and the other current reduction target value is 12A-0.25A=11.75A.
进一步地，若所述新接入车辆的拟充电电流等于所述新接入车辆连接的充电枪的限制充电电流时，则说明此时不能进行充电调控，因此所述处理单元20不计算所述第一电流调整值和所述第二电流调整值也不发送所述第一电流调升目标值或第一电流调降目标值或所述第二电流调升目标值或所述第二电流调降目标值至所述调控单元30。进一步地，所述调控单元30在未接收到所述第一电流调升目标值或第一电流调降目标值或所述第二电流调升目标值或所述第二电流调降目标值，停止调控所述新接入车辆的拟充电电流和所述已接入车辆的当前充电电流，则充电调控结束。可以理解，当所述调控单元30将所述新接入车辆的拟充电电流调升至所述新接入车辆连接的充电枪的限制充电电流后，充电调控结束。Further, if the proposed charging current of the newly connected vehicle is equal to the limited charging current of the charging gun connected to the newly connected vehicle, it means that charging control cannot be performed at this time, so the processing unit 20 does not calculate the The first current adjustment value and the second current adjustment value also do not send the first current increase target value or the first current decrease target value or the second current increase target value or the second current adjustment value. Decrease the target value to the control unit 30. Further, the adjusting unit 30 does not receive the first current increase target value or the first current decrease target value or the second current increase target value or the second current decrease target value, Stop regulating the proposed charging current of the newly connected vehicle and the current charging current of the connected vehicle, and then the charging regulation ends. It can be understood that after the regulation unit 30 increases the intended charging current of the newly connected vehicle to the limited charging current of the charging gun connected to the newly connected vehicle, the charging regulation ends.
进一步地，在本实施方式中，所述调控单元30将所述新接入车辆的拟充电电流调升一次并同时将所述已接入车辆的当前充电电流调降一次，则完成一次充电调控。所述通信单元40在所述调控单元30每完成一次充电调控后，则获取所述新接入车辆和所述已接入车辆的充电功率，并传送至所述处理单元20，所述处理单元20根据所述充电系统100的输出功率计算本次调控后的充电效率。进一步地，所述处理单元20在计算出充电效率后对应存储该次充电效率对应的所述新接入车辆的拟充电电流和所述已接入车辆的当前充电电流，以便于后续按照所述最大充电效率对应的充电电流控制所述新接入车辆和所述已接入车辆充电。例如：所述调控单元30进行充电调控后，所述新接入车辆的充电功率为20KW，所述已接入车辆的充电效率为50KW，所述充电系统的输出功率为100KW，则所述充电效率为（20KW+50KW）/100KW=70%。进一步地，当所述调控单元30调控完毕后，所述处理单元20则比较充电调控后的充电系统100的多次充电效率，并得出充电系统100的最大充电效率，同时对应选取所述充电系统100输出最大充电效率时所述新接入车辆的拟充电电流和所述已接入充电系统的当前充电电流并发送至所述调控单元30，所述调控单元30则按照所述拟充电电流控制所述新接入车辆进行充电，同时以所述当前充电电流控制所述已接入车辆进行充电。可以理解，若所述处理单元20计算出的充电效率为80%、81%、85%、90%，则所述充电系统的最大充电效率为90%，若所述充电系统充电效率为90%时对应的新接入车辆拟充电电流为30A、已接入车辆的当前充电电流为25A，则所述调控单元30控制所述新接入车辆按照30A进行充电，同时控制所述已接入车辆按照25A进行充电，从而保证所述充电系统100能够保持最大充电效率为车辆充电，从而提高所述充电系统100的充电效率。Further, in this embodiment, the control unit 30 increases the current charging current of the newly connected vehicle once and at the same time reduces the current charging current of the connected vehicle once to complete a charging control. . The communication unit 40 obtains the charging power of the newly connected vehicle and the connected vehicle after the control unit 30 completes one charging control, and transmits the charging power to the processing unit 20. The processing unit 20 Calculate the charging efficiency after this adjustment according to the output power of the charging system 100. Further, the processing unit 20 correspondingly stores the proposed charging current of the newly connected vehicle and the current charging current of the connected vehicle corresponding to the charging efficiency after calculating the charging efficiency, so as to facilitate subsequent follow-up The charging current corresponding to the maximum charging efficiency controls the charging of the newly connected vehicle and the connected vehicle. For example: after the regulation unit 30 performs charging regulation, the charging power of the newly connected vehicle is 20KW, the charging efficiency of the connected vehicle is 50KW, and the output power of the charging system is 100KW, then the charging The efficiency is (20KW+50KW)/100KW=70%. Further, after the adjustment by the adjustment unit 30 is completed, the processing unit 20 compares the multiple charging efficiency of the charging system 100 after the charging adjustment, and obtains the maximum charging efficiency of the charging system 100, and selects the charging system accordingly. When the system 100 outputs the maximum charging efficiency, the proposed charging current of the newly connected vehicle and the current charging current of the connected charging system are sent to the control unit 30, and the control unit 30 is based on the proposed charging current The newly connected vehicle is controlled to charge, and the current charging current is used to control the connected vehicle to charge. It can be understood that if the charging efficiency calculated by the processing unit 20 is 80%, 81%, 85%, 90%, the maximum charging efficiency of the charging system is 90%, and if the charging efficiency of the charging system is 90% When the corresponding proposed charging current of the newly connected vehicle is 30A, and the current charging current of the connected vehicle is 25A, the control unit 30 controls the newly connected vehicle to charge at 30A and controls the connected vehicle at the same time The charging is performed according to 25A, so as to ensure that the charging system 100 can maintain the maximum charging efficiency to charge the vehicle, thereby improving the charging efficiency of the charging system 100.
综上所述，本实施方式的充电系统能够充电系统新接入车辆进行充电时，调整所述新接入车辆和所述已接入车辆的充电电流从而得出所述充电系统充电效率最高时所述新接入车辆的拟充电电流和所述已接入车辆的当前充电电流，并控制所述新接入车辆和所述已接入车辆进行充电，从而保证所述充电系统的充电功率最大，避免了充电过程中出现的能源浪费，实现了充电控制智能化。In summary, the charging system of this embodiment can adjust the charging current of the newly connected vehicle and the connected vehicle when the charging system is newly connected to the vehicle to obtain the highest charging efficiency of the charging system. The proposed charging current of the newly connected vehicle and the current charging current of the connected vehicle, and controlling the newly connected vehicle and the connected vehicle to charge, thereby ensuring that the charging power of the charging system is maximized , To avoid the waste of energy in the charging process, and realize the intelligent charging control.

Each module in the above charging system can be implemented in whole or in part by software, hardware, and a combination thereof.

如图2所示，本发明另一较佳实施方式提出了一种充电方法，所述充电方法，应用于前述充电系统的任意实施例或实施例的排列、组合，包括以下步骤：As shown in FIG. 2, another preferred embodiment of the present invention proposes a charging method. The charging method is applied to any embodiment or permutation and combination of embodiments of the aforementioned charging system, and includes the following steps:
步骤S210：获取新接入车辆的充电需求。Step S210: Obtain the charging demand of the newly connected vehicle.
在本实施方式中，为了便于用户进行充电，在城市区域内的充电站或社区内安装充电系统以为用户的车辆充电。进一步地，所述充电系统至少包括两个充电枪，以同时接入至少两辆车辆进行充电。可以理解，所述充电系统可以为交流充电桩或直流充电桩。In this embodiment, in order to facilitate the user to charge, a charging system is installed in a charging station or a community in an urban area to charge the user's vehicle. Further, the charging system includes at least two charging guns to simultaneously connect to at least two vehicles for charging. It can be understood that the charging system may be an AC charging pile or a DC charging pile.
进一步地，在本实施方式中，车辆在使用所述充电系统进行充电时，需要将所述充电系统上的一个充电枪与车辆的充电口连接并通过扫码或刷卡的方式启动充电，当用户将充电枪与车辆连接并启动充电后，所述车辆即为新接入车辆，即可获取到所述新接入车辆的充电需求。进一步地，在本实施方式中，所述充电需求中至少需包括所述新接入车辆的需求充电电流，所述需求充电电流为所述车辆的电池能够承受的最大充电电流。Further, in this embodiment, when the vehicle uses the charging system for charging, it is necessary to connect a charging gun on the charging system to the charging port of the vehicle and start charging by scanning a code or swiping a card. After the charging gun is connected to the vehicle and charging is started, the vehicle is a newly connected vehicle, and the charging requirements of the newly connected vehicle can be obtained. Further, in this embodiment, the charging demand needs to include at least the required charging current of the newly connected vehicle, and the required charging current is the maximum charging current that the battery of the vehicle can withstand.
步骤S220：根据所述充电需求得出所述新接入车辆的拟充电电流。Step S220: derive the proposed charging current of the newly connected vehicle according to the charging demand.
进一步地，当接收到所述新接入车辆的充电需求后需要根据所述充电需求中的需求充电电流得出所述新接入车辆的拟充电电流。进一步地，在本实施方式中，由于所述充电系统具有至少两个充电枪，所述至少两个充电枪均由所述充电系统进行电能输出，则所述至少两个充电枪的充电电流不应超过所述最大输出电流，由于所述充电系统的可用充电电流等于所述充电系统的最大输出电流与使用中的充电电流的差值，因此新接入充电系统连接的充电枪的充电电流不应超过所述充电系统的可用充电电流。可以理解，由于不同充电枪的规格不同，因此不同的充电枪也具有响应最大充电电流，所述充电枪的输出电流也不应超过所述充电枪的最大充电电流。因此，在本实施方式中，根据充电枪的最大充电电流和所述充电系统的可用充电电流为每一充电枪设置限制充电电流，所述新接入车辆连接充电枪进行充电时的拟充电电流不得超过所述充电枪的限制充电电流，从而防止由于电流过大造成充电枪或充电系统损坏。进一步地，计算所述新接入车辆连接的充电枪的限制充电电流时，需要先获取充电系统使用中的充电电流，即所述充电系统已接入车辆的充电电流之和，并计算所述充电系统的可用充电电流，再根据所述新接入车辆连接的充电枪的最大充电电流从而得出所述充电枪的限制充电电流。Further, after receiving the charging demand of the newly connected vehicle, it is necessary to obtain the intended charging current of the newly connected vehicle according to the required charging current in the charging demand. Further, in this embodiment, since the charging system has at least two charging guns, and both of the at least two charging guns are outputted by the charging system, the charging current of the at least two charging guns is different. The maximum output current should be exceeded. Since the available charging current of the charging system is equal to the difference between the maximum output current of the charging system and the charging current in use, the charging current of the charging gun that is newly connected to the charging system is not The available charging current of the charging system should be exceeded. It can be understood that because different charging guns have different specifications, different charging guns also have a response maximum charging current, and the output current of the charging gun should not exceed the maximum charging current of the charging gun. Therefore, in this embodiment, a limit charging current is set for each charging gun according to the maximum charging current of the charging gun and the available charging current of the charging system, and the pseudo charging current when the newly connected vehicle is connected to the charging gun for charging The limited charging current of the charging gun must not be exceeded, so as to prevent damage to the charging gun or the charging system due to excessive current. Further, when calculating the limited charging current of the charging gun connected to the newly connected vehicle, it is necessary to first obtain the charging current in use of the charging system, that is, the sum of the charging currents of the vehicle connected to the charging system, and calculate the The available charging current of the charging system is then based on the maximum charging current of the charging gun connected to the newly connected vehicle to obtain the limited charging current of the charging gun.
步骤S230：根据所述拟充电电流及所述新接入车辆连接的充电枪的限制充电电流计算第一电流调整值或第二电流调整值。Step S230: Calculate the first current adjustment value or the second current adjustment value according to the proposed charging current and the limited charging current of the charging gun connected to the newly connected vehicle.
进一步地，计算出所述新接入车辆连接的充电枪的限制充电电流后，需要将所述新接入车辆的需求充电电流与所述充电枪的限制充电电流进行比较，从而得出所述新接入车辆的拟充电电流。可以理解，为了充电安全，在充电过程中，充电电流不应大于所述车辆的需求充电电流；进一步地，所述充电电流也不应大于所述充电枪的限制充电电流。因此，所述拟充电电流为所述需求充电电流和所述充电枪的限制充电电流中的较小值。Further, after calculating the limited charging current of the charging gun connected to the newly connected vehicle, it is necessary to compare the required charging current of the newly connected vehicle with the limited charging current of the charging gun to obtain the The proposed charging current of the newly connected vehicle. It can be understood that, for charging safety, during the charging process, the charging current should not be greater than the required charging current of the vehicle; further, the charging current should not be greater than the limited charging current of the charging gun. Therefore, the pseudo charging current is the smaller value of the required charging current and the limited charging current of the charging gun.
进一步地，在本实施方式中，所述限制充电电流为所述充电系统的可用充电电流和所述充电枪的最大充电电流中的较小值，所述可用充电电流为所述最大输出电流和使用中的充电电流的差值，所述使用中的充电电流为所述充电系统已接入车辆的充电电流之和，所述新接入车辆的拟充电电流为所述需求充电电流和所述充电枪的限制充电电流中的较小值。例如：所述充电系统的最大输出电流为100A，所述充电系统已接入车辆A和车辆B，其中车辆A的充电电流为30A，车辆B的充电电流为35A，则所述可用充电电流为100A-30A-35A=35A；所述车辆C为新接入车辆，所述车辆C连接的充电枪的最大充电电流为40A，则所述车辆C连接的车辆的限制充电电流为35A，若所述车辆C的需求充电电流为40A，则所述车辆C的拟充电电流为35A；若所述车辆C的需求充电电流为30A，则所述车辆C的拟充电电流为30A。可以理解，由于所述新接入车辆充电的过程中，所述充电系统将会根据充电效率调整所述新接入车辆的拟充电电流，因此所述拟充电电流不一定为所述新接入车辆的最终的充电电流，仅为所述新接入车辆在充电调控的过程中的过程充电电流。Further, in this embodiment, the limited charging current is the smaller of the available charging current of the charging system and the maximum charging current of the charging gun, and the available charging current is the sum of the maximum output current. The difference between the charging current in use, the charging current in use is the sum of the charging currents of the vehicles connected to the charging system, and the proposed charging current of the newly connected vehicle is the required charging current and the charging current The smaller value of the charging current limit of the charging gun. For example: the maximum output current of the charging system is 100A, the charging system has been connected to vehicle A and vehicle B, where the charging current of vehicle A is 30A, and the charging current of vehicle B is 35A, then the available charging current is 100A-30A-35A=35A; The vehicle C is a newly connected vehicle, and the maximum charging current of the charging gun connected to the vehicle C is 40A, and the limited charging current of the vehicle connected to the vehicle C is 35A. If the required charging current of the vehicle C is 40A, the pseudo charging current of the vehicle C is 35A; if the required charging current of the vehicle C is 30A, the pseudo charging current of the vehicle C is 30A. It can be understood that, since the charging system will adjust the proposed charging current of the newly connected vehicle according to the charging efficiency during the charging process of the newly connected vehicle, the proposed charging current may not necessarily be the newly connected vehicle. The final charging current of the vehicle is only the process charging current of the newly connected vehicle in the charging regulation process.
进一步地，当充电系统中新接入车辆后，由于不同车辆的充电效率不同，为了提高充电系统的充电效率，则需要再次计算分配所述充电系统的不同充电枪的充电电流，从而调整充电系统的已接入车辆的充电电流和新接入车辆的充电电流以使得所述充电系统的充电效率最大化。Further, when a new vehicle is connected to the charging system, because the charging efficiency of different vehicles is different, in order to improve the charging efficiency of the charging system, it is necessary to calculate the charging currents of different charging guns of the charging system again to adjust the charging system The charging current of the connected vehicle and the charging current of the newly connected vehicle are used to maximize the charging efficiency of the charging system.
进一步地，在本实施方式中，需要根据所述拟充电电流和所述新接入车辆连接的充电枪的限制充电电流计算第一电流调整值或第二电流调整值，并根据所述第一电流调整值或所述第二电流调整值调整所述充电系统的所述已接入车辆的充电电流和所述新接入车辆的充电电流，再计算调整充电电流后的充电系统的充电效率，从而使得充电效率最大化。Further, in this embodiment, it is necessary to calculate the first current adjustment value or the second current adjustment value according to the proposed charging current and the limited charging current of the charging gun connected to the newly connected vehicle, and to calculate the first current adjustment value or the second current adjustment value according to the first The current adjustment value or the second current adjustment value adjusts the charging current of the connected vehicle and the charging current of the newly connected vehicle of the charging system, and then calculates the charging efficiency of the charging system after adjusting the charging current, So as to maximize the charging efficiency.
进一步地，在本实施方式中，进行充电调控时，需要根据所述第一电流调整值或所述第二电流调整值调升所述新接入车辆的充电电流且调降所述已接入车辆的当前充电电流，因此仅在所述新接入车辆的拟充电电流小于所述新接入车辆连接的充电枪的限制充电电流时，才能够进行充电调控，因此在充电调控前，需要比较所述新接入车辆的拟充电电流和所述新接入车辆连接的充电枪的限制充电电流，并根据比较结果计算第一电流调整值或第二电流调整值并根据所述第一电流调整值或所述第二电流调整值进行充电调控。Further, in this embodiment, when performing charging adjustment, it is necessary to increase the charging current of the newly connected vehicle and decrease the charging current of the newly connected vehicle according to the first current adjustment value or the second current adjustment value. The current charging current of the vehicle, therefore, the charging control can be performed only when the proposed charging current of the newly connected vehicle is less than the limited charging current of the charging gun connected to the newly connected vehicle. Therefore, the charging control needs to be compared before the charging control. The proposed charging current of the newly connected vehicle and the limited charging current of the charging gun connected to the newly connected vehicle are calculated, and the first current adjustment value or the second current adjustment value is calculated according to the comparison result and adjusted according to the first current Value or the second current adjustment value for charging control.
进一步地，在本实施方式中，在进行充电调控的过程中，所述新接入车辆的拟充电电流不得大于所述新接入车辆连接的充电枪的限制充电电流，否则将会导致车辆或充电系统损坏。因此，在调控的过程中需要判断所述拟充电电流与充电枪的限制充电电流的关系，以防止在调控时导致所述新接入车辆的拟充电电流超过所述新接入车辆连接的充电枪的限制充电电流的情况。进一步地，若所述新接入车辆的拟充电电流调升所述第一电流调整值后，不会超过所述限制充电电流，则按照所述第一电流调整值进行调控；若所述新接入车辆的拟充电电流调升所述第一电流调整值后，会超过所述限制充电电流，将按照所述第二电流调整值进行调控；若所述新接入车辆的拟充电电流等于所述限制充电电流，则不需要再进行充电调控，否则调控后所述拟充电电流将会超过所述限制充电电流，从而带来安全隐患。Further, in this embodiment, during the charging control process, the proposed charging current of the newly connected vehicle shall not be greater than the limited charging current of the charging gun connected to the newly connected vehicle, otherwise it will cause the vehicle or The charging system is damaged. Therefore, it is necessary to determine the relationship between the proposed charging current and the limited charging current of the charging gun during the adjustment process, so as to prevent the proposed charging current of the newly connected vehicle from exceeding the charging current of the newly connected vehicle during the adjustment. The gun’s limited charging current situation. Further, if the proposed charging current of the newly connected vehicle does not exceed the limited charging current after the first current adjustment value is increased, then the adjustment is performed according to the first current adjustment value; if the new After the pseudo charging current of the connected vehicle is increased by the first current adjustment value, it will exceed the limited charging current and will be regulated according to the second current adjustment value; if the pseudo charging current of the newly connected vehicle is equal to The limited charging current does not need to be adjusted for charging, otherwise the pseudo-charging current after the adjustment will exceed the limited charging current, which may cause safety hazards.
进一步地，在本实施方式中，在所述新接入车辆的拟充电电流小于所述新接入车辆连接的充电枪的限制充电电流时，计算所述第一电流调整值。可以理解，在本实施方式中，为了保证电流调整的精度和效率，所述第一电流调整值与所述新接入车辆的拟充电电流和所述充电枪的最大充电电流相关，即所述新接入车辆的拟充电电流和所述充电枪的最大充电电流较低时，所述第一电流调整值相对较低；所述新接入车辆的拟充电电流和所述充电枪的最大充电电流较大时，所述第一电流调整值相对较高，从而保证电流调控的效率和精度。进一步地，在所述拟充电电流小于所述新接入车辆连接的充电枪的限制充电电流且所述新接入车辆连接的充电枪的限制充电电流不大于第一预设值时，得出所述第一电流调整值为所述第一预设值与预设系数的乘积；在所述拟充电电流大于第一预设值且不大于所述新接入车辆连接的充电枪的限制充电电流且所述新接入车辆连接的充电枪的限制充电电流不大于所述第二预设值时，得出所述第一电流调整值为所述第二预设值与所述预设系数的乘积。进一步地，在本实施方式中，所述第一预设值为6A，所述第二预设值为63A，预设系数为1%。可以理解，所述预设系数越低则进行充电调控时的幅度越小，充电调控的次数越多，因此计算出来的所述充电效率的精度和准确度越高。但是，由于所述预设系数较低时，充电调控的次数越多，因此可能所需的调控时间将会较长，因此为了保证调控的精度和效率，可根据需要设置所述预设系数，例如将所述预设系数可为5%，10%等。进一步地，例如：当所述新接入车辆连接的充电枪的限制充电电流为5A，所述新接入车辆的拟充电电流为4A时，则所述第一电流调整值为6A*1%=0.06A；当所述新接入车辆连接的充电枪的限制充电电流为32A，所述新接入车辆的拟充电电流为30A，则所述第一电流调整值为63A*1%=0.63A。Further, in this embodiment, when the intended charging current of the newly connected vehicle is less than the limited charging current of the charging gun connected to the newly connected vehicle, the first current adjustment value is calculated. It can be understood that, in this embodiment, in order to ensure the accuracy and efficiency of current adjustment, the first current adjustment value is related to the proposed charging current of the newly connected vehicle and the maximum charging current of the charging gun, that is, the When the proposed charging current of the newly connected vehicle and the maximum charging current of the charging gun are low, the first current adjustment value is relatively low; the proposed charging current of the newly connected vehicle and the maximum charging current of the charging gun When the current is large, the first current adjustment value is relatively high, thereby ensuring the efficiency and accuracy of current control. Further, when the proposed charging current is less than the limited charging current of the charging gun connected to the newly connected vehicle and the limited charging current of the charging gun connected to the newly connected vehicle is not greater than a first preset value, it is obtained The first current adjustment value is the product of the first preset value and a preset coefficient; when the proposed charging current is greater than the first preset value and not greater than the limited charging of the charging gun connected to the newly connected vehicle When the current and the limited charging current of the charging gun connected to the newly connected vehicle is not greater than the second preset value, it is obtained that the first current adjustment value is the second preset value and the preset coefficient The product of. Further, in this embodiment, the first preset value is 6A, the second preset value is 63A, and the preset coefficient is 1%. It can be understood that the lower the preset coefficient, the smaller the amplitude during charging adjustment and the greater the number of charging adjustments, and therefore the higher the accuracy and accuracy of the calculated charging efficiency. However, since the preset coefficient is lower, the number of charging adjustments is greater, so the adjustment time may be longer. Therefore, in order to ensure the accuracy and efficiency of adjustment, the preset coefficient can be set as required. For example, the preset coefficient may be 5%, 10%, etc. Further, for example: when the limited charging current of the charging gun connected to the newly connected vehicle is 5A, and the proposed charging current of the newly connected vehicle is 4A, the first current adjustment value is 6A*1% =0.06A; when the limited charging current of the charging gun connected to the newly connected vehicle is 32A, and the proposed charging current of the newly connected vehicle is 30A, the first current adjustment value is 63A*1%=0.63 A.
进一步地，当计算出所述第一电流调整值后，需要进一步判断所述拟充电电流能否调升所述第一电流调整值，因此进一步将所述新接入车辆的拟充电电流与所述第一电流调整值相加来判断是否大于所述限制充电电流。可以理解，若所述接入车辆的拟充电电流与所述第一电流调整值相加大于所述拟充电电流，则说明进行充电调控后所述拟充电电流将会超过所述充电枪的限制充电电流，因此不允许将所述拟充电电流调升所述第一电流调整值，而仅能将所述拟充电电流调升所述第二电流调整值；若所述新接入车辆的拟充电电流与所述第一电流调整值相加不大于所述充电枪的限制充电电流，则说明进行充电调控后所述拟充电电流将不会超过充电枪的所述限制充电电流，因此允许将所述拟充电电流调升所述第一电流调整值。Further, after the first current adjustment value is calculated, it is necessary to further determine whether the proposed charging current can increase the first current adjustment value. Therefore, the proposed charging current of the newly connected vehicle is further compared with the current adjustment value. The first current adjustment value is added to determine whether it is greater than the limited charging current. It can be understood that if the sum of the pseudo-charging current of the connected vehicle and the first current adjustment value is greater than the pseudo-charging current, it means that the pseudo-charging current will exceed the limit of the charging gun after the charging control is performed. Charging current, therefore, it is not allowed to increase the proposed charging current by the first current adjustment value, and only the proposed charging current can be increased by the second current adjustment value; if the proposed charging current is newly connected to the vehicle The sum of the charging current and the first current adjustment value is not greater than the limited charging current of the charging gun, which means that the pseudo-charging current will not exceed the limited charging current of the charging gun after the charging adjustment is performed. Therefore, it is allowed to change The proposed charging current increases the first current adjustment value.
因此，在本实施方式中，在所述新接入车辆的拟充电电流与所述第一电流调整值之和不大于所述新接入车辆连接的充电枪的限制充电电流时，需要根据所述第一电流调整值计算第一电流调升目标值及至少一第一电流调降目标值并发送所述第一电流调升目标值及至少一第一电流调降目标值。进一步地，在本实施方式中，所述第一电流调升目标值为所述新接入车辆的拟充电电流与所述第一电流调整值之和，所述第一电流调降目标值为一所述已接入车辆的当前充电电流与第三电流调整值之差，所述第三电流调整值为所述第一电流调整值与所述已接入车辆的数量的比值。例如：所述第一电流调整值为0.63A，所述新接入车辆的拟充电电流为6A，所述新接入车辆为1辆，且当前充电电流为10A，则所述第一电流调升目标值为6A+0.63A=6.63A，所述第三电流调整值为0.63A/1=0.63A，所述第一电流调降目标值为6A-0.63A=5.37A；若所述新接入车辆为2辆，且一辆的当前充电电流为10A，另一辆的当前充电电流为9A，则所述第三电流调整值为0.63A/3=0.21A，由于所述当前接入车辆为两辆，则所述第一电流调降目标值为2个，一个电流调降目标值为10A-0.21A=9.79A，另一个电流调降目标值为9A-0.21A=8.79A。Therefore, in this embodiment, when the sum of the proposed charging current of the newly connected vehicle and the first current adjustment value is not greater than the limited charging current of the charging gun connected to the newly connected vehicle, it is necessary to The first current adjustment value calculates a first current increase target value and at least one first current decrease target value, and sends the first current increase target value and at least one first current decrease target value. Further, in this embodiment, the first current increase target value is the sum of the proposed charging current of the newly connected vehicle and the first current adjustment value, and the first current decrease target value is A difference between the current charging current of the connected vehicle and a third current adjustment value, where the third current adjustment value is a ratio of the first current adjustment value to the number of connected vehicles. For example: the first current adjustment value is 0.63A, the proposed charging current of the newly connected vehicle is 6A, the newly connected vehicle is 1 vehicle, and the current charging current is 10A, then the first current adjustment The increase target value is 6A+0.63A=6.63A, the third current adjustment value is 0.63A/1=0.63A, and the first current decrease target value is 6A-0.63A=5.37A; if the new There are two connected vehicles, and the current charging current of one vehicle is 10A, and the current charging current of the other vehicle is 9A, then the third current adjustment value is 0.63A/3=0.21A, because the current access If there are two vehicles, the first current reduction target value is two, one current reduction target value is 10A-0.21A=9.79A, and the other current reduction target value is 9A-0.21A=8.79A.

Further, in this embodiment, the second current adjustment value is the difference between the limited charging current of the charging gun connected to the newly connected vehicle and the pseudo-charging current of the newly connected vehicle. For example: the required charging current of the vehicle is 30A, the maximum charging current of the charging gun connected to the newly connected vehicle is 45A, the first current adjustment value is 0.63A, and the proposed charging current of the newly connected vehicle If it is 29.5A, the limited charging current of the charging gun connected to the newly connected vehicle is 30A, and the second current adjustment value is 30A-29.5A=0.5A. Further, in this embodiment, the second current increase target value is the sum of the proposed charging current of the newly connected vehicle and the second current adjustment value, and the second current decrease target value is A difference between the current charging current of the connected vehicle and a fourth current adjustment value, where the fourth current adjustment value is a ratio of the second current adjustment value to the number of connected vehicles. For example: the second current adjustment value is 0.5A, the proposed charging current of the newly connected vehicle is 8A, the connected vehicle is 1 vehicle, and the charging current is 11A, then the second current is increased The target value is 8A+0.5A=8.5A, the fourth current adjustment value is 0.5A/1=0.5A, and the second current reduction target value is 11A-0.5A=10.5A; If there are two vehicles entering, and one vehicle has a charging current of 11A, and the other vehicle has a charging current of 12A, the fourth current adjustment value is 0.5A/2=0.25A, and the second current reduction target value is Two, one current reduction target value is 11A-0.25A=9.75A, and the other current reduction target value is 12A-0.25A=11.75A.
进一步地，若所述新接入车辆的拟充电电流等于所述新接入车辆连接的充电枪的限制充电电流时，则说明此时不能进行充电调控，因此不计算所述第一电流调整值和所述第二电流调整值也不发送所述第一电流调升目标值或第一电流调降目标值或所述第二电流调升目标值或所述第二电流调降目标值。Further, if the proposed charging current of the newly connected vehicle is equal to the limited charging current of the charging gun connected to the newly connected vehicle, it means that charging control cannot be performed at this time, so the first current adjustment value is not calculated And the second current adjustment value does not send the first current increase target value or the first current decrease target value or the second current increase target value or the second current decrease target value.
