进一步地，用户在需要对车辆进行充电时，可以先将所述拟充电设备与所述车辆进行充电连接，再通过扫码或刷卡等方式开启所述拟充电设备。可以理解，当用户开启所述拟充电设备后，所述拟充电设备将充电需求发送至所述充电需求获取单元310，所述充电需求获取单元310即可获取到所述拟充电设备的充电需求。
进一步地，所述充电需求获取单元310接收到所述充电需求后将所述充电需求发送给所述分析单元330，所述分析单元330通过所述电力获取单元10获取所述拟充电设备所在相线内的其他所有充电设备的充电电流，并计算所述拟充电电流。
进一步地，所述分析单元330内存储有所述相线内所有充电设备的编号信息，所述分析单元330将所述相线内充电设备的编号信息发送至所述电力获取单元10并通过所述电力获取单元10获取到对应的所述充电设备的充电电流。
进一步地，所述分析单元330接收到所述充电电流后，将所述充电设备的充电电流叠加以获取所述相线当前的第一实时电力负载，并计算所述相线当前的空闲电流和/或可用电流。
进一步地，在本实施方式中，所述空闲电流为所述相线内的第一电流调降阈值与所述第一实时电力负载的差值。可以理解，若所述第一电流阈值为200A，所述第一实时电力负载为180A，则所述空闲电流为20A。
进一步地，在本实施方式中，所述可用电流为所述空闲电流与电流调整值之和。进一步地，所述电流调整值为所述相线内的所有所述充电设备的可调电流值之和，所述可调电流值为所述充电设备的充电电流与电流启动值的差值。进一步，计算所述可用电流时需要先计算出所述相线内每一充电设备的可调电流值，再将所述可调电流值叠加得到所述电流调整值，再通过所述电流调整值计算出所述可用电流。可以理解，若所述相线内当前所有充电设备的数量为3个，分别为充电设备A、充电设备B和充电设备C，充电设备A的充电电流为9A，充电设备B的充电电流为11A，充电设备C的充电电流为12A，电流启动值为6A，空闲电流为20A，则所述充电设备A的可调电流值为9A-6A=3A，所述充电设备B的可调电流值为11A-6A=5A，所述充电设备C的可调电流值为12A-6A=6A，则所述电流调整值为3A+5A+6A=14A，所述可用电流为20A+14A=34A。
进一步地，在本实施方式中，所述分析单元330在所述可用电流小于所述电流启动值时，得出所述拟充电电流为零。具体地，例如所述分析单元330在所述可用电流为4A时，由于本实施方式中所述电流启动值为6A，则所述可用电流小于所述电流启动值，说明此时所述相线内的可用电流不足以启动所述拟充电设备的充电功能。换言之，此时在保证所述相线的第一实时电力负载不超过所述第一电流调降阈值的情况下即使将所述相线内所有充电设备的充电电流调整至6A时所述相线内的可用电流仅为4A，此时若要启动所述拟充电设备的充电功能，将会使得所述相线内部分充电设备的充电电流电流调降值6A以下，进而导致所述相线内充电设备的充电电流小于所述电流启动值进而关闭，影响所述相线内所述充电设备的正常充电。因此，所述分析单元330在所述可用电流小于所述电流启动值时，不允许启动所述拟充电设备的充电功能，因此得出所述拟充电电流为零。
进一步地，所述控制单元350在接收到所述拟充电电流为零时，将不启动所述拟充电设备的充电功能。进一步地，所述控制单元350将所述拟充电设备加入预约充电序列，在所述可用电流不小于所述电流启动值时，再启动所述拟充电设备的充电功能。
进一步地，在本实施方式中，所述分析单元330在所述可用电流不小于所述电流启动值，且所述空闲电流小于所述电流启动值时，得出所述拟充电电流为第一电流调降阈值与充电设备总数量的比值，所述充电设备总数量为所述相线内的充电设备的数量和所述拟充电设备的充电数量之和。具体地，例如所述分析单元330在所述可用电流为16A，所述空闲电流为4A时，由于本实施方式中所述电流启动值为6A，因此所述空闲电流小于所述电流启动值且所述可用电流不小于所述电流启动值，说明此时的空闲电流不足以启动所述拟充电设备的充电功能但可以调配所述相线内其他充电设备的充电电流至所述拟充电设备从而启动所述拟充电设备的充电功能。换言之，此时在保证所述相线的第一实时电力负载不超过所述第一电流调降阈值的情况下可以将所述相线的所有电流重新分配至所述相线内的充电设备和所述拟充电设备从而保证所述相线内的充电设备和所述拟充电设备的充电功能，因此得出所述拟充电电流为所述第一电流调降阈值与所述充电设备总数量的比值。具体地，例如所述相线内的充电设备的数量为3个，所述第一调降阈值为80A，所述拟充电设备的数量为1个，则所述充电设备的总数量为3+1=4，所述拟充电电流为80A/4=20A。亦即，所述分析单元330在所述可用电流不小于所述电流启动值，且所述空闲电流小于所述电流启动值时，先将所述相线内所有充电设备的数量与所述拟充电设备的数量相加得到充电设备的总数量，并将所述第一电流调降阈值的电流值平均分配至所述相线内的充电设备和所述拟充电设备从而能够满足所述相线内的充电设备和所述拟充电设备的充电需求。进一步地，由于将所述第一电流调降阈值的电流值平均分配至所述相线内的充电设备和所述拟充电设备，使得所述相线的第一实时电力负载不超过所述第一电流调降阈值，避免触发所述电力调控系统100的充电调控。
进一步地，所述控制单元350在接收到所述拟充电电流为所述第一电流调降阈值与所述充电设备总数量的比值时，启动所述拟充电设备的充电功能并控制所述相线内所有的充电设备和所述拟充电设备按照所述拟充电电流或所述电流上限值进行充电。进一步地，由于所述电流上限值为32A，若所述拟充电电流大于32A，即大于所述电流上限值，则所述充电设备不能输出所述拟充电电流，此时所述控制单元350控制所述相线内所有的充电设备和所述拟充电设备按照所述电流上限值进行充电；若所述拟充电电流不大于32A，即不大于所述电流上限值，则所述拟充电电流未超过所述电流上限值，所述充电设备能够输出所述拟充电电流，此时所述控制单元350控制所述相线内所有的充电设备和所述拟充电设备按照所述拟充电电流进行充电。
进一步地，在本实施方式中，所述分析单元330在所述空闲电流不小于所述电流启动值且小于电流上限值时，得出所述拟充电电流为所述电流启动值。具体地，例如所述分析单元330在所述空闲电流为10A时，由于本实施方式中所述电流启动值为6A，所述电流上限值为32A，因此所述空闲电流不小于所述电流启动值且小于所述电流上限值32A，说明当前的空闲电流足以启动所述拟充电设备的充电功能但不足以使得所述拟充电设备以所述电流上限值进行充电，因此仅需保证所述充电电流能够满足所述拟充电设备的充电需求即可，此时所述分析单元330得出所述拟充电电流为所述电流启动值。
进一步地，所述控制单元350在所述拟充电电流为所述电流启动值时，启动所述拟充电设备的充电功能并控制所述拟充电设备按照所述电流启动值进行充电。可以理解，此种情况下，所述控制单元350无需调控所述相线内其他充电设备的充电电流，仅需启动所述拟充电设备的充电功能并按照所述电流启动值控制所述拟充电设备进行充电即可。
进一步地，在本实施方式中， 所述分析单元330在所述空闲电流不小于所述电流上限值时，得出所述拟充电电流为所述电流上限值。具体地，所述分析单元360在所述空闲电流为33A时，由于本实施方式中所述电流上限值为32A，所述空闲电流大于所述电流上限值，说明当前的空闲电流足以启动所述拟充电设备的充电功能，而且能够允许所述拟充电设备以电流上限值进行充电，此时所述分析单元330得出所述拟充电电流为所述电流上限值。
进一步地，所述控制单元350在所述拟充电电流为所述电流上限值时，启动所述拟充电设备的充电功能并控制所述拟充电设备按照所述电流上限值进行充电。可以理解，此种情况下，所述控制单元350无需调控所述相线内其他充电设备的充电电流，仅需启动所述拟充电设备的充电功能并按照所述电流上限值控制所述充电设备进行充电即可。
可以理解，每接入一个拟充电设备时，所述分析单元330均需要根据所述相线内的所述第一实时电力负载和所述第一可用电力计算所述拟充电电流，从而保证在不触发所述电力调控系统100的充电调控的情况下满足所述拟充电设备的充电需求。
本发明的充电控制系统能够获取用户的充电需求，并根据当前相线的可用电力和空闲电力分析能否满足所述拟充电设备的充电需求，并计算所述拟充电电流，从而在所述相线电力允许的范围内启动所述拟充电设备的充电功能，保证了充电的灵活性和充电管理的智能化。
请参考图5，本发明第四实施方式提供一种充电方法，所述充电方法应用于前述充电控制系统的任意实施方式或实施方式的排列、组合，包括以下步骤：
步骤S410：获取相线内接入的拟充电设备的充电需求。
进一步地，在本实施方式中，由于所述电力调控系统100中对于所述相线设置了第一电流调降阈值，因此当所述相线内新接入的拟充电设备需要从所述相线上中获取电流进行充电，因此会导致所述相线上的第一实时电力负载增高，在所述第一实时电力负载持续增高出现电流过载时将会触发所述电力调控系统100对产生电流过载的相线、回路或变压器内的充电设备的充电调控，从而调降其他所述充电设备的充电电流，影响其他所述充电设备的充电效率，因此在所述相线内新接入所述拟充电设备时，需要根据所述相线的第一电流调降阈值对所述拟充电设备进行充电控制从而在不触发所述电力调控系统100的电力调控的情况下尽可能保证所述新接入的充电设备能够正常充电。
进一步地，在本实施方式中，所述充电设备设置电流启动值和电流上限值，所述充电设备的充电电流可在所述电流启动值和所述电流上限值之间进行调控，即调升或调降。具体地，在本实施方式中，所述电流启动值为6A，所述电流上限值为32A。可以理解，当所述充电设备的充电电流小于所述电流启动值时，所述充电设备则不能启动充电功能。
进一步地，用户在需要对车辆进行充电时，可以先将所述拟充电设备与所述车辆进行充电连接，再通过扫码或刷卡等方式开启所述拟充电设备。可以理解，当用户开启所述拟充电设备后，即可获取到所述拟充电设备的充电需求。
步骤S420：计算空闲电流和/或可用电流，并根据所述空闲电流和/或所述可用电流得出拟充电电流。
进一步地，获取到所述拟充电设备的充电需求后，需要进一步获取所述拟充电设备所在相线内的其他所有充电设备的充电电流，并计算所述拟充电电流。
进一步地，获取所述其他所有充电设备的充电电流时，先将所述相线内充电设备的编号信息发送至所述电力调控系统100内的电力获取单元10从而获取到对应的所述充电设备的充电电流。
进一步地，接收到所述充电设备的充电电流后，将所述充电设备的充电电流叠加以获取所述相线当前的第一实时电力负载，并计算所述相线当前的空闲电流和/或可用电流。
进一步地，在本实施方式中，所述空闲电流为所述相线内的第一电流调降阈值与所述第一实时电力负载的差值。可以理解，若所述第一电流阈值为200A，所述第一实时电力负载为180A，则所述空闲电流为20A。
进一步地，在本实施方式中，所述可用电流为所述空闲电流与电流调整值之和。进一步地，所述电流调整值为所述相线内的所有所述充电设备的可调电流值之和，所述可调电流值为所述充电设备的充电电流与电流启动值的差值。进一步，计算所述可用电流时需要先计算出所述相线内每一充电设备的可调电流值，再将所述可调电流值叠加得到所述电流调整值，再通过所述电流调整值计算出所述可用电流。可以理解，若所述相线内当前所有充电设备的数量为3个，分别为充电设备A、充电设备B和充电设备C，充电设备A的充电电流为9A，充电设备B的充电电流为11A，充电设备C的充电电流为12A，电流启动值为6A，空闲电流为20A，则所述充电设备A的可调电流值为9A-6A=3A，所述充电设备B的可调电流值为11A-6A=5A，所述充电设备C的可调电流值为12A-6A=6A，则所述电流调整值为3A+5A+6A=14A，所述可用电流为20A+14A=34A。
进一步地，在本实施方式中，在所述可用电流小于所述电流启动值时，得出所述拟充电电流为零。具体地，在所述可用电流为4A时，由于本实施方式中所述电流启动值为6A，则所述可用电流小于所述电流启动值，说明此时所述相线内的可用电流不足以启动所述拟充电设备的充电功能。换言之，此时在保证所述相线的第一实时电力负载不超过所述第一电流调降阈值的情况下即使将所述相线内所有充电设备的充电电流调整至6A时所述相线内的可用电流仅为4A，此时若要启动所述拟充电设备的充电功能，将会使得所述相线内部分充电设备的充电电流电流调降值6A以下，进而导致所述相线内充电设备的充电电流小于所述电流启动值进而关闭，影响所述相线内所述充电设备的正常充电。因此，在所述可用电流小于所述电流启动值时，不允许启动所述拟充电设备的充电功能，因此得出所述拟充电电流为零。
当所述可用电流小于所述电流启动值时，说明即使将所有充电的充电设备的电流调降至所述电流启动值时，所述相线内的可用电流仍不能达到所述充电设备的电流启动值，因此若要启动发起充电需求的充电设备的充电功能，将会导致所述相线内的第一实时电力负载超过所述第一电流调降阈值，进而触发所述电力调控系统100的充电调控，从而调降所述相线内所有充电设备的充电电流，导致部分充电设备的充电电流低于所述电流启动值从而关闭，影响其他用户的充电。
进一步地，在本实施方式中，所述分析单元330在所述可用电流不小于所述电流启动值时，且所述空闲电流小于所述电流启动值时，得出所述拟充电电流为第一电流调降阈值与充电设备总数量的比值，所述充电设备总数量为所述相线内所有充电设备的数量和所述拟充电设备的数量之和。具体地，例如在所述可用电流为16A，所述空闲电流为4A时，由于本实施方式中所述电流启动值为6A，因此所述空闲电流小于所述电流启动值且所述可用电流不小于所述电流启动值，说明此时的空闲电流不足以启动所述拟充电设备的充电功能但可以调配所述相线内其他充电设备的充电电流至所述拟充电设备从而启动所述拟充电设备的充电功能。换言之，此时在保证所述相线的第一实时电力负载不超过所述第一电流调降阈值的情况下可以将所述相线的所有电流重新分配至所述相线内的充电设备和所述拟充电设备从而保证所述相线内的充电设备和所述拟充电设备的充电功能，因此得出所述拟充电电流为第一电流调降阈值与充电设备总数量的比值。具体地，例如此时所述相线内的充电设备的数量为3个，所述第一调降阈值为80A，所述拟充电设备的数量为1个，则所述充电设备的总数为3+1=4，所述拟充电电流为80A/4=20A。亦即，在所述可用电流不小于所述电流启动值，且所述空闲电流小于所述电流启动值时，先将所述相线内所有充电设备的数量与所述拟充电设备的数量相加得到充电设备的总数量，并将所述第一电流调降阈值的电流值平均分配至所述相线内的充电设备和所述拟充电设备从而能够满足所述相线内的充电设备和所述拟充电设备的充电需求。进一步地，由于将所述第一电流调降阈值的电流值平均分配至所述相线内的充电设备和所述拟充电设备，使得所述相线的第一实时电力负载不超过所述第一电流调降阈值，避免触发所述电力调控系统100的充电调控。进一步地，在本实施方式中，在所述空闲电流不小于所述电流启动值且小于电流上限值时，得出所述拟充电电流为所述电流启动值。具体地，在所述空闲电流为10A时，由于本实施方式中所述电流启动值为6A，所述电流上限值为32A，因此所述空闲电流不小于所述电流启动值且小于所述电流上限值32A，说明当前的空闲电流足以启动所述拟充电设备的充电功能但不足以使得所述拟充电设备以所述电流上限值进行充电，因此仅需保证所述充电电流能够满足所述拟充电设备的充电需求即可，此时得出所述拟充电电流为所述电流启动值。
进一步地，在本实施方式中，在所述空闲电流不小于所述电流上限值时，说明当前的空闲电流足以启动所述拟充电设备的充电功能，而且能够允许所述拟充电设备以电流上限值进行充电，此时得出所述拟充电电流为所述电流上限值。具体地，在所述空闲电流为33A时，由于本实施方式中所述电流上限值为32A，所述空闲电流大于所述电流上限值，说明当前的空闲电流足以启动所述拟充电设备的充电功能，而且能够允许所述拟充电设备以所述电流上限值进行充电，此时得出所述拟充电电流为所述电流上限值。
步骤S430：根据所述拟充电电流启动或关闭所述拟充电设备的充电功能。
进一步地，接收到所述拟充电电流后，能够根据所述拟充电电流控制所述拟充电设备是否启动充电。
进一步地，在本实施方式中，当所述拟充电电流为零时，在接收到所述拟充电电流为零时，将不启动所述拟充电设备的充电功能。进一步地，将所述拟充电设备加入预约充电序列，在所述可用电流不小于所述电流启动值时，再启动所述拟充电设备的充电功能。
进一步地，在本实施方式中，在接收到所述拟充电电流为所述第一电流调降阈值与所述充电设备总数量的比值时，启动所述拟充电设备的充电功能并控制所述相线内所有的充电设备和所述拟充电设备按照所述拟充电电流或所述电流上限值进行充电。进一步地，由于所述电流上限值为32A，若所述拟充电电流大于32A，即大于所述电流上限值，则所述充电设备不能输出所述拟充电电流，此时控制所述相线内所有的充电设备和所述拟充电设备按照所述电流上限值进行充电；若所述拟充电电流不大于32A，即不大于所述电流上限值，则所述拟充电电流未超过所述电流上限值，所述充电设备能够输出所述拟充电电流，此时所述控制单元350控制所述相线内所有的充电设备和所述拟充电设备按照所述拟充电电流进行充电。
进一步地，在本实施方式中，在接收到所述拟充电电流为所述电流启动值时，启动所述拟充电设备的充电功能并控制所述拟充电设备按照所述电流启动值进行充电。可以理解，此种情况下，无需调控所述相线内其他充电设备的充电电流，仅需启动所述拟充电设备的充电功能并按照所述电流启动值控制所述拟充电设备进行充电即可。
进一步地，在本实施方式中，在接收到所述拟充电电流为所述电流上限值时，启动所述拟充电设备的充电功能并控制所述拟充电设备按照所述电流上限值进行充电。可以理解，此种情况下，无需调控所述相线内其他充电设备的充电电流，仅需启动所述拟充电设备的充电功能并按照所述电流上限值控制所述充电设备进行充电即可。
可以理解，每接入一个拟充电设备时，均需要按照本方法所述的步骤判断是否能够启动所述拟充电设备，并根据所述相线内的所述第一实时电力负载和所述第一可用电力计算所述拟充电电流，从而保证在不触发所述电力调控系统100的充电调控的情况下满足所述拟充电设备的充电需求。
