请参考图1，图1示出了本发明一较佳实施方式的充电调控系统的结构框图。
在本实施方式中，在社区中，为了便于居民充电，在社区停车位附近设置充电设备以便于用户将车辆停入停车位后使用所述充电设备进行供电。进一步地，在本实施方式中，社区内所有所述充电设备均接入充电调控系统100中，以接收所述充电调控系统100的调控指令进行充电调控。进一步地，在本实施方式中，所述充电调控系统100用于对电网内一条相线上的充电设备进行充电调控，所述相线上的充电设备每新接入一辆充电车辆，该充电设备则为拟充电设备，所述充电调控系统100能够根据电网的电力负载情况对所述拟充电设备进行充电调控以保证所述拟充电设备为新接入电网的车辆进行供电。
进一步地，所述充电调控系统100包括充电需求获取单元10、比较单元20、第一供电单元30、第二供电单元40、开关单元50、控制单元60及查询单元70，所述充电需求获取单元10、所述比较单元20、所述开关单元50、所述查询单元70均与所述控制单元60电性连接，所述第一供电单元30和所述第二供电单元40与所述开关单元50电性连接。
进一步，在本实施方式中，社区的电力控制系统周期性地查询所述社区内居民用电线路的用电功率和充电线路的用电功率，并根据电网容量、所述居民用电线路的用电功率和所述充电线路的用电功率计算所述相线的可用充电功率，并将可用充电功率信息传送至所述控制单元60并由所述控制单元60根据所述可用充电功率信息调控所述相线内充电中的充电设备的充电功率。所述社区电力系统计算出所述可用充电功率后将可用充电功率信息传送至所述控制单元60并由所述控制单元60根据所述可用充电功率信息调控所述充电中的充电设备的充电功率。在本实施方式中，所述可用充电功率信息包括所述可用充电功率的数值，所述可用功率的数值为所述电网容量与所述用电总功率的差值，所述用电总功率为居民用电线路的用电功率与充电线路的用电功率之和。可以理解，例如：所述社区电力控制系统的充电调控周期为1小时，即所述社区电力控制系统每间隔1小时查询所述居民用电线路的用电功率和充电线路的用电功率并计算所述可用充电功率，由于所述居民用电线路的用电功率根据居民用电情况的不同处于变化的状态，因此所述社区电力调控系统每次充电调控时计算的可用充电功率不同，所述可用充电功率的数值有可能大于或小于所述相线内所有充电中的的充电设备的当前的充电功率之和，因此在调控的过程中所述控制单元60会根据所述可用充电功率信息调降或调升所述充电中的充电设备的充电功率。
进一步地，在本实施方式中，当所述控制单元60接收到可用充电功率信息后将会计算所述可用充电功率的分配方案，并根据计算得到的所述分配方案计算所述充电中的充电设备的目标充电功率信息，并下发所述目标充电功率至所述相线内的充电中的充电设备从而进行充电调控。可以理解，所述目标充电功率为所述充电中的充电设备拟达到的充电功率，即在充电调控过程结束后，所述充电中的充电设备的充电功率为所述目标充电功率。例如，所述充电中的充电设备的充电功率为5KW，所述目标充电功率为10KW，则所述充电中的充电设备需要将所述充电功率由5KW调整至10KW。进一步地，所述控制单元60同时记录下发目标充电功率的时间作为充电调控时间。在本实施方式中，所述充电中的充电设备在接收到所述目标充电功率信息，将会在预设时间内将当前充电功率调整至所述控制单元60发送的目标充电功率，以实现充电调控。可以理解，所述充电设备用于为车辆充电，由于车辆电池特性原因，当所述充电设备的充电功率调高或调低时，所述车辆电池可接受的充电功率需要经历一定时间才能调整至所述目标功率，因此所述充电中的充电设备需要经过预设时间才能调整至所述目标功率。进一步地，当充电调控开始后时间未超过所述预设时间时，由于充电功率正在进行调控，处于变化过程中，因此所述相线内的负载不稳定；当充电调控开始后的时间超过所述预设时间时，所述充电功率调整完毕，处于相对稳定的状态，因此所述相线内的负载稳定。进一步地，所述充电中的充电设备接收到所述目标充电功率后，需要与连接的车辆进行通信以确定所述车辆是否能够承受所述目标充电功率，因此当所述车辆不能承受所述目标充电功率时，所述充电功率不能施加于所述充电中的充电设备，从而成为所述相线内的空闲充电功率。
进一步地，所述充电需求获取单元10用于获取所述拟充电设备的充电需求并记录充电接入时间，所述比较单元20用于接收所述充电接入时间并从所述控制单元60获取上一次的充电调控时间并比较所述充电接入时间和所述上一次的充电调控时间以比较结果，所述控制单元60用于接收社区电网中计算的可用充电功率信息并对根据所述可用充电功率信息对充电中的充电设备进行充电调控，还用于接收所述比较单元20的比较结果并根据所述比较结果控制所述开关单元50的工作状态进而控制所述第一供电单元30或所述第二供电单元40为所述拟充电设备进行供电。进一步地，在本实施方式中，所述上一次的充电调控时间为所述控制单元60记录的与所述充电接入时间的差值最小的一次充电调控的时间。例如：所述控制单元60记录的充电调控时间为08:50、09:10、09:30，所述充电接入时间为09:31，则所述比较单元20获取的所述上一次的充电调控时间为09:30。进一步地，在本实施方式中，所述第一供电单元30为与电网连接的充电接口，用于接入电网以为所述拟充电设备进行供电，所述第二供电单元40为能够存储备用能源进行充电的装置，如蓄电池等，以为所述拟充电设备进行供电。
进一步地，用户在需要对车辆进行供电时，可以先将所述拟充电设备与所述车辆进行连接，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10，所述充电需求获取单元10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10获取到所述拟充电设备的充电需求时同时记录接收到所述充电需求的时间，以作为所述拟充电设备的充电接入时间。可以理解，所述充电接入时间为所述充电需求单元10获取到所述拟充电设备的充电需求的时间。进一步地，所述充电需求获取单元10获取到所述充电需求和充电接入时间后传送至所述比较单元20，以便于后续根据所述充电接入时间分析如何进行充电调控。
进一步地，所述比较单元20在接收到所述充电接入时间后向所述控制单元60获取上一次的充电调控时间并将所述充电接入时间与所述上一次的充电调控时间比较以得出比较结果。进一步地，在本实施方式中，所述比较结果包括所述充电接入时间与所述上一次的充电调控时间的差值不小于预设时间，或所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间。进一步地，所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于预设时间，则说明此时所述相线未处于充电调控过程中，即负载稳定状态；所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值小于预设时间，则说明此时所述相线处于充电调控过程中，即负载不稳定状态。可以理解，由于充电设备接收到充电功率分配方案后需要预设时间才能调整至目标充电功率，因此在预设时间内，所述相线内的充电设备的充电功率，即充电负载处于持续上升或下降的过程中，此时所述充电设备的充电功率处于持续变化的状态。若所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间，则说明所述拟充电设备接入时，所述相线内的充电设备的充电功率处于相对不变的状态，即负载稳定；若所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间，则说明所述拟充电设备接入时，所述相线内的充电设备的充电功率仍处于持续变化的状态，即负载不稳定。
进一步地，所述比较单元20得出所述比较结果后将所述比较结果传送至所述控制单元60以便于所述控制单元60根据所述比较结果进行充电调控。进一步地，当负载稳定时，所述控制单元60发送查询指令至所述查询单元70，以查询所述相线内的空闲充电功率。进一步地，所述查询指令中包括所述相线当前可用的充电功率，所述查询单元70进一步查询所述相线内充电中的充电设备的当前充电功率，并将所述当前充电功率相加，再通过所述相线当前的可用充电功率减去所述充电中的充电设备的当前充电功率之和从而得出空闲充电功率，即所述空闲充电功率为所述可用充电功率与所述充电中的充电设备的总功率的差值，所述充电中的充电设备的总功率为所有所述充电中的充电设备的充电功率之和。例如：所述相线内的充电设备为充电设备A和B，充电设备A的当前充电功率为10KW，充电设备B的当前充电功率为5KW，所述相线当前可用充电功率信息为30KW，则所述空闲充电功率为30KW-(10KW+5KW)=15KW。进一步地，所述查询单元70查询出所述空闲充电功率后将所述空闲充电功率传送至所述控制单元60以对所述拟充电设备进行充电调控。
进一步地，在本实施方式中，所述开关单元50包括第一工作状态，第二工作状态和第三工作状态，所述开关单元50能够在所述控制单元60的控制下从而工作在所述第一工作状态、所述第二工作状态或所述第三工作状态从而切换所述第一供电单元30或所述第二供电单元40的供电。
进一步地，所述控制单元60在所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间时，控制所述开关单元50切换至所述第一工作状态；所述控制单元60在所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率小于所述拟充电设备的启动充电功率时，控制所述开关切换至所述第一工作状态；所述控制单元60在所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率不小于所述拟充电设备的启动充电功率且不大于所述拟充电设备的限制充电功率时，控制所述开关切换至所述第二工作状态；所述控制单元60在所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间并所述空闲充电功率大于所述拟充电设备的限制充电功率时，控制所述开关单元切换至所述第三工作状态。
进一步地，所述控制单元60接收到所述空闲充电功率后，进一步根据所述空闲充电功率控制所述开关单元50的工作状态从而控制所述第一供电单元30或所述第二供电单元40为所述拟充电设备的充电。进一步地，所述控制单元60接收到所述空闲充电功率后，进一步查询所述拟充电设备的启动充电功率及限制充电功率，从而比较所述空闲充电功率与所述启动充电功率及所述限制充电功率的关系，进而确定所述拟充电设备的充电功率。进一步地，在本实施方式中，所述启动充电功率为启动所述充电设备的充电功能所需要的最小功率，所述限制充电功率为所述拟充电设备的最大充电功率及所述拟充电设备连接的车辆的最大充电功率中较小的一个。例如：所述拟充电设备的最大充电功率为20KW，所述拟充电设备连接的车辆的最大充电功率为15KW，则所述拟充电设备的限制充电功率为15KW。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间时，说明所述相线内的充电设备处于充电调控的状态中，不能准确计算出所述相线的空闲充电功率，此时所述控制单元60控制所述开关单元50切换至第一工作状态从而使得所述拟充电设备与所述第二供电单元40接通进而使得所述第二供电单元40为所述拟充电设备进行供电。进一步地，所述第二供电单元40仅用于在所述电网电力不足时临时启动所述拟充电设备的充电功能，因此在该种情况下所述第二供电单元40以所述启动充电功率为所述拟充电设备进行供电，待下次所述控制单元60进行充电调控时再调整所述拟充电设备的充电功率。
进一步地，所述控制单元60在所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率小于所述拟充电设备的启动充电功率时，说明所述相线当前的空闲充电功率不足以启动所述拟充电设备的充电功能，此时不能通过所述电网为所述拟充电设备进行供电，即不能通过所述第一供电单元30为所述拟充电设备进行供电。此时所述控制单元60控制所述开关单元50切换至第一工作状态从而使得所述拟充电设备与所述第二供电单元40接通进而使得所述第二供电单元40为所述拟充电设备进行供电。进一步地，所述第二供电单元40仅用于在所述电网电力不足时临时启动所述拟充电设备的充电功能，因此所述第二供电单元40仅需保证能够启动所述拟充电设备的充电即可，此时所述控制单元60控制所述第二供电单元40以启动充电功率为所述拟充电设备进行供电。
进一步地，所述控制单元60在所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间并所述空闲充电功率不小于所述拟充电设备的启动充电功率且不大于所述拟充电设备的限制充电功率时，说明所述相线当前的充电功率足以启动所述拟充电设备的充电功能，此时能够通过所述电网为所述拟充电设备进行供电，即能够通过所述第一供电单元30为所述拟充电设备进行供电。此时，所述控制单元60控制所述开关单元50切换至第二工作状态从而使得所述拟充电设备与所述第一供电单元30接通进而使得所述第一供电单元30为所述拟充电设备进行供电。进一步地，由于所述相线内的充电设备的充电功率已经相对稳定，因此此时所述空闲充电功率可以全部输送至所述拟充电设备以启动所述拟充电设备的充电，此时所述控制单元60控制所述第一供电单元30以所述空闲充电功率为所述拟充电设备进行供电。
进一步地，所述控制单元60在所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率大于所述拟充电设备的限制充电功率时，说明当前的空闲充电功率足以启动所述拟充电设备的充电功能，而且超出了所述拟充电设备的承受范围，此时所述控制单元60控制所述开关单元50切换至第三工作状态从而使得所述第一供电单元30与所述拟充电设备及所述第二供电单元40接通进而使得所述第一供电单元30为所述拟充电设备及所述第二供电单元40进行供电。可以理解，由于所述第二供电单元40存储有备用电源，因此当通过所述第二供电单元40为所述拟充电设备供电后，所述第二供电单元40的电量逐渐减少，此时通过所述第一供电单元30为所述第二供电单元40充电可以恢复所述第二供电单元40的电量，以便于在空闲充电功率不足时为所述拟充电设备充电。此时，所述控制单元60控制所述拟充电设备以第一充电功率进行供电，控制所述第二供电单元40以第二充电功率进行供电。进一步地，在本实施方式中，所述第一充电功率等于所述拟充电设备的限制充电功率，所述第二充电功率等于所述空闲充电功率与所述第一充电功率的差值。
综上所述，本实施方式的充电调控系统能够根据社区电网的负载情况对电网的相线内充电中的充电设备进行充电调控，而且能够在所述相线新接入充电设备时根据电网的充电调控情况通过第一供电单元或第二供电单元启动所述拟充电设备的充电，从而保证车辆在接入充电设备时就能够启动充电功能，满足了用户的充电需求。而且能够在社区电网电力较为充足时通过所述第一供电单元为所述第二供电单元供电以保证所述第二供电单元的电量从而便于在电网电力不足时通过所述第二供电单元启动所述拟充电设备的充电功能，实现了充电的灵活性和便利性。
上述充电调控系统中的各个模块的划分仅用于举例说明，在其他实施方式中，可将充电调控系统按照需要划分为不同的模块，以完成上述充电调控系统的全部或部分功能。上述充电调控系统中的各个模块可全部或部分通过软件、硬件及其组合来实现。上述各模块可以硬件形式内嵌于或独立于计算机设备中的处理器中，也可以软件形式存储于计算机设备的存储器中，以便于处理器调用执行以上各个模块对应的操作。
如图2所示，本发明另一较佳实施方式提出了一种充电调控方法，用于针对充电设备进行预约充电，所述充电调控方法，应用于前述充电调控系统的任意实施例或实施例的排列、组合，包括以下步骤：
步骤S210：接收拟充电设备的充电需求并记录充电接入时间。
在本实施方式中，在社区中，为了便于居民充电，在社区停车位附近设置充电设备以便于用户将车辆停入停车位后使用所述充电设备进行供电。进一步地，在本实施方式中，社区内所有所述充电设备均接入充电调控系统中，以接收所述充电调控系统的调控指令进行充电调控。进一步地，在本实施方式中，所述充电调控系统用于对电网内一条相线上的充电设备进行充电调控，所述相线上的充电设备每新接入一辆充电车辆，该充电设备则为拟充电设备，所述充电调控系统能够根据电网的电力负载情况对所述拟充电设备进行充电调控以保证所述拟充电设备为新接入电网的车辆进行供电。
进一步地，用户在需要对车辆进行供电时，可以先将所述拟充电设备与所述车辆进行连接，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。进一步地，获取到所述拟充电设备的充电需求时同时记录接收到所述充电需求的时间，以作为所述拟充电设备的充电接入时间。可以理解，所述充电接入时间为获取到所述拟充电设备的充电需求的时间。
步骤S220：接收可用充电功率信息以对充电中的充电设备进行充电调控，并记录充电调控时间。
进一步，在本实施方式中，所述社区的电力控制系统周期性地查询所述社区内居民用电线路的用电功率和充电线路的用电功率，并根据电网容量、所述居民用电线路的用电功率和所述充电线路的用电功率计算所述相线的可用充电功率，并根据所述可用充电功率对所述相线内充电中的充电设备进行周期性地充电调控。在本实施方式中，所述可用充电功率信息包括所述可用充电功率的数值，所述可用功率的数值为所述电网容量与所述用电总功率的差值，所述用电总功率为居民用电线路的用电功率与充电线路的用电功率之和。可以理解，例如：所述社区电力控制系统的充电调控周期为1小时，即所述社区电力控制系统每间隔1小时查询所述居民用电线路的用电功率和充电线路的用电功率并计算所述可用充电功率，由于所述居民用电线路的用电功率根据居民用电情况的不同处于变化的状态，因此所述社区电力调控系统每次充电调控时计算的可用充电功率不同，所述可用充电功率的数值有可能大于或小于所述相线内所有充电中的的充电设备的当前的充电功率之和，因此在调控的过程中会根据所述可用充电功率信息调降或调升所述充电中的充电设备的充电功率。所述充电中的充电设备接收到所述可用充电功率信息后根据所述可用充电功率信息调控所述充电中的充电设备的充电功率。
进一步地，在本实施方式中，接收到可用充电功率信息后将会计算所述可用充电功率的分配方案，并根据计算得到的所述分配方案计算所述充电中的充电设备的目标充电功率信息，并下发所述目标充电功率至所述相线内的充电中的充电设备从而进行充电调控。可以理解，所述目标充电功率为所述充电中的充电设备拟达到的充电功率，即在充电调控过程结束后，所述充电中的充电设备的充电功率为所述目标充电功率。例如，所述充电中的充电设备的充电功率为5KW，所述目标充电功率为10KW，则所述充电中的充电设备需要将所述充电功率由5KW调整至10KW。进一步地，同时记录下发目标充电功率的时间作为充电调控时间。在本实施方式中，所述充电中的充电设备在接收到所述目标充电功率信息，将会在预设时间内将当前充电功率调整至发送的目标充电功率，以实现充电调控。可以理解，所述充电设备用于为车辆充电，由于车辆电池特性原因，当所述充电设备的充电功率调高或调低时，所述车辆电池可接受的充电功率需要经历一定时间才能调整至所述目标功率，因此所述充电中的充电设备需要经过预设时间才能调整至所述目标功率。进一步地，当充电调控开始后时间未超过所述预设时间时，由于充电功率正在进行调控，处于变化过程中，因此所述相线内的负载不稳定；当充电调控开始后的时间超过所述预设时间时，所述充电功率调整完毕，处于相对稳定的状态，因此所述相线内的负载稳定。进一步地，所述充电中的充电设备接收到所述目标充电功率后，需要与连接的车辆进行通信以确定所述车辆是否能够承受所述目标充电功率，因此当所述车辆不能承受所述目标充电功率时，所述充电功率不能施加于所述充电中的充电设备，从而成为所述相线内的空闲充电功率。
步骤S230：获取上一次的充电调控时间并比较所述充电接入时间和所述上一次的充电调控时间以得出比较结果。
进一步地，在接收到所述充电接入时间后即可查询上一次的充电调控时间并将所述充电接入时间与所述上一次的充电调控时间比较以得出比较结果。进一步地，在本实施方式中，所述上一次的充电调控时间为与所述充电接入时间的差值最小的一次充电调控的时间。例如：记录的充电调控时间为08:50、09:10、09:30，所述充电接入时间为09:31，则所述比较单元20获取的所述上一次的充电调控时间为09:30。进一步地，在本实施方式中，所述比较结果包括所述充电接入时间与所述上一次的充电调控时间的差值不小于预设时间，或所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间。进一步地，所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于预设时间，则说明此时所述相线未处于充电调控过程中，即负载稳定状态；所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值小于预设时间，则说明此时所述相线处于充电调控过程中，即负载不稳定状态。可以理解，由于充电设备接收到充电功率分配方案后需要预设时间才能调整至目标充电功率，因此在预设时间内，所述相线内的充电设备的充电功率，即充电负载处于持续上升或下降的过程中，此时所述充电设备的充电功率处于持续变化的状态。若所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间，则说明所述拟充电设备接入时，所述相线内的充电设备的充电功率处于相对不变的状态，即负载稳定；若所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间，则说明所述拟充电设备接入时，所述相线内的充电设备的充电功率仍处于持续变化的状态，即负载不稳定。
步骤S240：根据所述比较结果控制第一供电单元或第二供电单元为所述拟充电设备进行供电。
进一步地，在本实施方式中，进行充电调控时需要根据比较结果控制开关单元的工作状态进而控制第一供电单元或第二供电单元进行供电。进一步地，在本实施方式中，所述开关单元包括第一工作状态，第二工作状态和第三工作状态，所述开关单元能够工作在所述第一工作状态、所述第二工作状态或所述第三工作状态从而切换所述第一供电单元或所述第二供电单元的供电。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于预设时间时，说明当前负载稳定，能够进行充电调控，此时需要查询所述相线内的空闲充电功率并根据所述相线内的空闲充电功率对新接入的拟充电设备进行充电调控。具体地，查询空闲功率前需要查询所述相线内充电中的充电设备的当前充电功率，并将所述当前充电功率相加，再通过所述相线当前的可用充电功率减去所述充电中的充电设备的当前充电功率之和从而得出空闲充电功率，即所述空闲充电功率为所述可用充电功率与所述充电中的充电设备的总功率的差值，所述充电中的充电设备的总功率为所有所述充电中的充电设备的充电功率之和。例如：所述相线内的充电设备为充电设备A和B，充电设备A的当前充电功率为10KW，充电设备B的当前充电功率为5KW，所述相线当前可用充电功率信息为30KW，则所述空闲充电功率为30KW-(10KW+5KW)=15KW。
进一步地，接收到所述空闲充电功率后，进一步查询所述拟充电设备的启动充电功率及限制充电功率，从而比较所述空闲充电功率与所述启动充电功率及所述限制充电功率的关系，进而确定所述拟充电设备的充电功率。进一步地，在本实施方式中，所述启动充电功率为启动所述充电设备的充电功能所需要的最小功率，所述限制充电功率为所述拟充电设备的最大充电功率及所述拟充电设备连接的车辆的最大充电功率中较小的一个。例如：所述拟充电设备的最大充电功率为20KW，所述拟充电设备连接的车辆的最大充电功率为15KW，则所述拟充电设备的限制充电功率为15KW。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间时，所述开关单元切换至所述第一工作状态；当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率小于所述拟充电设备的启动充电功率时，控制所述开关切换至所述第一工作状态；当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率不小于所述拟充电设备的启动充电功率且不大于所述拟充电设备的限制充电功率时，所述开关切换至所述第二工作状态；当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间并所述空闲充电功率大于所述拟充电设备的限制充电功率时，所述开关单元切换至所述第三工作状态。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间时，说明所述相线内的充电设备处于充电调控的状态中，不能准确计算出所述相线的空闲充电功率，此时所述开关单元切换至第一工作状态从而使得所述拟充电设备与所述第二供电单元接通进而使得所述第二供电单元为所述拟充电设备进行供电。进一步地，所述第二供电单元仅用于在所述电网电力不足时临时启动所述拟充电设备的充电功能，因此在该种情况下所述第二供电单元以所述启动充电功率为所述拟充电设备进行供电，待下次所述控制单元进行充电调控时再调整所述拟充电设备的充电功率。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率小于所述拟充电设备的启动充电功率时，说明所述相线当前的空闲充电功率不足以启动所述拟充电设备的充电功能，此时不能通过所述电网为所述拟充电设备进行供电，即不能通过所述第一供电单元为所述拟充电设备进行供电。此时所述开关单元切换至第一工作状态从而使得所述拟充电设备与所述第二供电单元接通进而使得所述第二供电单元为所述拟充电设备进行供电。进一步地，所述第二供电单元仅用于在所述电网电力不足时临时启动所述拟充电设备的充电功能，因此所述第二供电单元仅需保证能够启动所述拟充电设备的充电即可，此时所述控制单元控制所述第二供电单元以启动充电功率为所述拟充电设备进行供电。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率不小于所述拟充电设备的启动充电功率且不大于所述拟充电设备的限制充电功率时，说明所述相线当前的充电功率足以启动所述拟充电设备的充电功能，此时能够通过所述电网为所述拟充电设备进行供电，即能够通过所述第一供电单元为所述拟充电设备进行供电。此时，所述开关单元切换至第二工作状态从而使得所述拟充电设备与所述第一供电单元接通进而使得所述第一供电单元为所述拟充电设备进行供电。进一步地，由于所述相线内的充电设备的充电功率已经相对稳定，因此此时所述空闲充电功率可以全部输送至所述拟充电设备以启动所述拟充电设备的充电，此时控制所述第一供电单元30以所述空闲充电功率为所述拟充电设备进行供电。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率大于所述拟充电设备的限制充电功率时，说明当前的空闲充电功率足以启动所述拟充电设备的充电功能，而且超出了所述拟充电设备的承受范围，此时所述开关单元切换至第三工作状态从而使得所述第一供电单元与所述拟充电设备及所述第二供电单元接通进而使得所述第一供电单元为所述拟充电设备及所述第二供电单元进行供电。可以理解，由于所述第二供电单元存储有备用电源，因此当通过所述第二供电单元为所述拟充电设备供电后，所述第二供电单元的电量逐渐减少，此时通过所述第一供电单元为所述第二供电单元充电可以恢复所述第二供电单元的电量，以便于在空闲充电功率不足时为所述拟充电设备充电。此时，所述控制所述拟充电设备以第一充电功率进行供电，控制所述第二供电单元以第二充电功率进行供电。进一步地，在本实施方式中，所述第一充电功率等于所述拟充电设备的限制充电功率，所述第二充电功率等于所述空闲充电功率与所述第一充电功率的差值。
综上所述，本实施方式的充电调控方法能够根据社区电网的负载情况对电网的相线内充电中的充电设备进行充电调控，而且能够在所述相线新接入充电设备时根据电网的充电调控情况通过第一供电单元或第二供电单元启动所述拟充电设备的充电，从而保证车辆在接入充电设备时就能够启动充电功能，满足了用户的充电需求。而且能够在社区电网电力较为充足时通过所述第一供电单元为所述第二供电单元供电以保证所述第二供电单元的电量从而便于在电网电力不足时通过所述第二供电单元启动所述拟充电设备的充电功能，实现了充电的灵活性和便利性。
如图2所示，本发明另一较佳实施方式提出了一种充电调控方法，用于针对电网中新接入的充电设备进行充电调控，所述充电调控方法包括以下步骤：
步骤S210：接收拟充电设备的充电需求并记录充电接入时间。
在本实施方式中，在社区中，为了便于居民充电，在社区停车位附近设置充电设备以便于用户将车辆停入停车位后使用所述充电设备进行供电。进一步地，在本实施方式中，社区内所有所述充电设备均接入充电调控系统中，以接收所述充电调控系统的调控指令进行充电调控。进一步地，在本实施方式中，所述充电调控系统用于对电网内一条相线上的充电设备进行充电调控，所述相线上的充电设备每新接入一辆充电车辆，该充电设备则为拟充电设备，所述充电调控系统能够根据电网的电力负载情况对所述拟充电设备进行充电调控以保证所述拟充电设备为新接入电网的车辆进行供电。
进一步地，用户在需要对车辆进行供电时，可以先将所述拟充电设备与所述车辆进行连接，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。进一步地，获取到所述拟充电设备的充电需求时同时记录接收到所述充电需求的时间，以作为所述拟充电设备的充电接入时间。可以理解，所述充电接入时间为获取到所述拟充电设备的充电需求的时间。
步骤S220：接收可用充电功率信息以对充电中的充电设备进行充电调控，并记录充电调控时间。
进一步，在本实施方式中，所述社区的电力控制系统周期性地查询所述社区内居民用电线路的用电功率和充电线路的用电功率，并根据电网容量、所述居民用电线路的用电功率和所述充电线路的用电功率计算所述相线的可用充电功率，并根据所述可用充电功率对所述相线内充电中的充电设备进行周期性地充电调控。在本实施方式中，所述可用充电功率信息包括所述可用充电功率的数值，所述可用功率的数值为所述电网容量与所述用电总功率的差值，所述用电总功率为居民用电线路的用电功率与充电线路的用电功率之和。可以理解，例如：所述社区电力控制系统的充电调控周期为1小时，即所述社区电力控制系统每间隔1小时查询所述居民用电线路的用电功率和充电线路的用电功率并计算所述可用充电功率，由于所述居民用电线路的用电功率根据居民用电情况的不同处于变化的状态，因此所述社区电力调控系统每次充电调控时计算的可用充电功率不同，所述可用充电功率的数值有可能大于或小于所述相线内所有充电中的充电设备的当前的充电功率之和，因此在调控的过程中会根据所述可用充电功率信息调降或调升所述充电中的充电设备的充电功率。所述充电中的充电设备接收到所述可用充电功率信息后根据所述可用充电功率信息调控所述充电中的充电设备的充电功率。
进一步地，在本实施方式中，接收到可用充电功率信息后将会计算所述可用充电功率的分配方案，并根据计算得到的所述分配方案计算所述充电中的充电设备的目标充电功率信息，并下发所述目标充电功率至所述相线内的充电中的充电设备从而进行充电调控。可以理解，所述目标充电功率信息包括目标充电功率的数值，所述目标充电功率为所述充电中的充电设备拟达到的充电功率，即在充电调控过程结束后，所述充电中的充电设备的充电功率为所述目标充电功率。例如，所述充电中的充电设备的充电功率为5KW，所述目标充电功率为10KW，则所述充电中的充电设备需要将所述充电功率由5KW调整至10KW。进一步地，同时记录下发目标充电功率的时间作为充电调控时间。在本实施方式中，所述充电中的充电设备在接收到所述目标充电功率信息，将会在预设时间内将当前充电功率调整至发送的目标充电功率，以实现充电调控。可以理解，所述充电设备用于为车辆充电，由于车辆电池特性原因，当所述充电设备的充电功率调高或调低时，所述车辆电池可接受的充电功率需要经历一定时间才能调整至所述目标功率，因此所述充电中的充电设备需要经过预设时间才能调整至所述目标功率。进一步地，当充电调控开始后时间未超过所述预设时间时，由于充电功率正在进行调控，处于变化过程中，因此所述相线内的负载不稳定；当充电调控开始后的时间超过所述预设时间时，所述充电功率调整完毕，处于相对稳定的状态，因此所述相线内的负载稳定。进一步地，所述充电中的充电设备接收到所述目标充电功率后，需要与连接的车辆进行通信以确定所述车辆是否能够承受所述目标充电功率，因此当所述车辆不能承受所述目标充电功率时，所述充电功率不能施加于所述充电中的充电设备，从而成为所述相线内的空闲充电功率。
步骤S230：获取上一次的充电调控时间并比较所述充电接入时间和所述上一次的充电调控时间以得出比较结果。
进一步地，在接收到所述充电接入时间后即可查询上一次的充电调控时间并将所述充电接入时间与所述上一次的充电调控时间比较以得出比较结果。进一步地，在本实施方式中，所述上一次的充电调控时间为与所述充电接入时间的差值最小的一次充电调控的时间。例如：记录的充电调控时间为08:50、09:10、09:30，所述充电接入时间为09:31，则所述比较单元20获取的所述上一次的充电调控时间为09:30。进一步地，在本实施方式中，所述比较结果包括所述充电接入时间与所述上一次的充电调控时间的差值不小于预设时间，或所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间。进一步地，所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于预设时间，则说明此时所述相线未处于充电调控过程中，即负载稳定状态；所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值小于预设时间，则说明此时所述相线处于充电调控过程中，即负载不稳定状态。可以理解，由于充电设备接收到充电功率分配方案后需要预设时间才能调整至目标充电功率，因此在预设时间内，所述相线内的充电设备的充电功率，即充电负载处于持续上升或下降的过程中，此时所述充电设备的充电功率处于持续变化的状态。若所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间，则说明所述拟充电设备接入时，所述相线内的充电设备的充电功率处于相对不变的状态，即负载稳定；若所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间，则说明所述拟充电设备接入时，所述相线内的充电设备的充电功率仍处于持续变化的状态，即负载不稳定。
步骤S240：根据所述比较结果控制第一供电单元或第二供电单元为所述拟充电设备进行供电。
进一步地，在本实施方式中，进行充电调控时需要根据比较结果控制开关单元的工作状态进而控制第一供电单元或第二供电单元进行供电。进一步地，在本实施方式中，所述开关单元包括第一工作状态，第二工作状态和第三工作状态，所述开关单元能够工作在所述第一工作状态、所述第二工作状态或所述第三工作状态从而切换所述第一供电单元或所述第二供电单元的供电。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于预设时间时，说明当前负载稳定，能够进行充电调控，此时需要查询所述相线内的空闲充电功率并根据所述相线内的空闲充电功率对新接入的拟充电设备进行充电调控。具体地，查询空闲功率前需要查询所述相线内充电中的充电设备的当前充电功率，并将所述当前充电功率相加，再通过所述相线当前的可用充电功率减去所述充电中的充电设备的当前充电功率之和从而得出空闲充电功率，即所述空闲充电功率为所述可用充电功率与所述充电中的充电设备的总功率的差值，所述充电中的充电设备的总功率为所有所述充电中的充电设备的充电功率之和。例如：所述相线内的充电设备为充电设备A和B，充电设备A的当前充电功率为10KW，充电设备B的当前充电功率为5KW，所述相线当前可用充电功率信息为30KW，则所述空闲充电功率为30KW-(10KW+5KW)=15KW。
进一步地，接收到所述空闲充电功率后，进一步查询所述拟充电设备的启动充电功率及限制充电功率，从而比较所述空闲充电功率与所述启动充电功率及所述限制充电功率的关系，进而确定所述拟充电设备的充电功率。进一步地，在本实施方式中，所述启动充电功率为启动所述充电设备的充电功能所需要的最小功率，所述限制充电功率为所述拟充电设备的最大充电功率及所述拟充电设备连接的车辆的最大充电功率中较小的一个。例如：所述拟充电设备的最大充电功率为20KW，所述拟充电设备连接的车辆的最大充电功率为15KW，则所述拟充电设备的限制充电功率为15KW。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间时，所述开关单元切换至所述第一工作状态；当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率小于所述拟充电设备的启动充电功率时，控制所述开关切换至所述第一工作状态；当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率不小于所述拟充电设备的启动充电功率且不大于所述拟充电设备的限制充电功率时，所述开关切换至所述第二工作状态；当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间并所述空闲充电功率大于所述拟充电设备的限制充电功率时，所述开关单元切换至所述第三工作状态。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值小于所述预设时间时，说明所述相线内的充电设备处于充电调控的状态中，不能准确计算出所述相线的空闲充电功率，此时所述开关单元切换至第一工作状态从而使得所述拟充电设备与所述第二供电单元接通进而使得所述第二供电单元为所述拟充电设备进行供电。进一步地，所述第二供电单元仅用于在所述电网电力不足时临时启动所述拟充电设备的充电功能，因此在该种情况下所述第二供电单元以所述启动充电功率为所述拟充电设备进行供电，待下次所述控制单元进行充电调控时再调整所述拟充电设备的充电功率。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率小于所述拟充电设备的启动充电功率时，说明所述相线当前的空闲充电功率不足以启动所述拟充电设备的充电功能，此时不能通过所述电网为所述拟充电设备进行供电，即不能通过所述第一供电单元为所述拟充电设备进行供电。此时所述开关单元切换至第一工作状态从而使得所述拟充电设备与所述第二供电单元接通进而使得所述第二供电单元为所述拟充电设备进行供电。进一步地，所述第二供电单元仅用于在所述电网电力不足时临时启动所述拟充电设备的充电功能，因此所述第二供电单元仅需保证能够启动所述拟充电设备的充电即可，此时所述控制单元控制所述第二供电单元以启动充电功率为所述拟充电设备进行供电。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率不小于所述拟充电设备的启动充电功率且不大于所述拟充电设备的限制充电功率时，说明所述相线当前的充电功率足以启动所述拟充电设备的充电功能，此时能够通过所述电网为所述拟充电设备进行供电，即能够通过所述第一供电单元为所述拟充电设备进行供电。此时，所述开关单元切换至第二工作状态从而使得所述拟充电设备与所述第一供电单元接通进而使得所述第一供电单元为所述拟充电设备进行供电。进一步地，由于所述相线内的充电设备的充电功率已经相对稳定，因此此时所述空闲充电功率可以全部输送至所述拟充电设备以启动所述拟充电设备的充电，此时控制所述第一供电单元30以所述空闲充电功率为所述拟充电设备进行供电。
进一步地，当所述比较结果为所述充电接入时间与所述上一次的充电调控时间的差值不小于所述预设时间且所述空闲充电功率大于所述拟充电设备的限制充电功率时，说明当前的空闲充电功率足以启动所述拟充电设备的充电功能，而且超出了所述拟充电设备的承受范围，此时所述开关单元切换至第三工作状态从而使得所述第一供电单元与所述拟充电设备及所述第二供电单元接通进而使得所述第一供电单元为所述拟充电设备及所述第二供电单元进行供电。可以理解，由于所述第二供电单元存储有备用电源，因此当通过所述第二供电单元为所述拟充电设备供电后，所述第二供电单元的电量逐渐减少，此时通过所述第一供电单元为所述第二供电单元充电可以恢复所述第二供电单元的电量，以便于在空闲充电功率不足时为所述拟充电设备充电。此时，所述控制所述拟充电设备以第一充电功率进行供电，控制所述第二供电单元以第二充电功率进行供电。进一步地，在本实施方式中，所述第一充电功率等于所述拟充电设备的限制充电功率，所述第二充电功率等于所述空闲充电功率与所述第一充电功率的差值。
