本发明实施例提供一种充电调控方法，该充电调控方法应用于集中式充电***或充电站。请参考图1，充电***200包括充电云平台201及若干充电设备202，充电设备202为电动汽车203充电，充电云平台201与充电设备202及外部电网连接，是充电***200的控制平台，用于存储充电数据，处理数据，发送控制指令等。充电云平台201还与移动终端204连接，用户可通过移动终端204读取充电数据或发送控制指令等。
请参考图2，所述充电调控方法，包括：
步骤S10，接收待充电设备的充电指令；
步骤S20，根据所述充电指令获取当前充电设备的充电数据，根据所述充电数据对所述当前充电设备进行排序，形成第一序列，根据所述第一序列确定功率调降充电设备，控制所述功率调降充电设备调降预设功率W 预设；并且，步骤S30，根据所述充电指令触发控制所述待充电设备以所述预设功率W 预设开启充电；
步骤S40，获取更新的充电数据，根据所述更新的充电数据确定剩余负载L 剩余；以及，
步骤S50，根据所述剩余负载L 剩余及预设规则控制被调降的功率调降充电设备调升输出功率。
本实施例中，应用于充电***的充电调控方法，其执行主体为充电云 平台，充电云平台完成接收指令、处理数据、发送指令、传输数据等动作。所述步骤S10中，充电云平台接收充电指令，所述充电指令为电动汽车提出充电需求的充电指令，具体包括充电开启时间、充电时间、充电需求电量、待充电功率等数据中的至少一种数据。所述充电指令具体可由充电设备202发出或者通过用户移动终端204发出，用户通过充电设备202设置相关充电参数形成所述充电指令，或者通过移动终端204设定相关充电参数形成所述充电指令。可以理解，在其他实施例中，所述充电调控方法的执行主体还可以为一种充电调控装置，充电调控装置被配置为与充电***的充电云平台或用户终端通讯连接，能够完成接收指令、处理数据、发送指令、传输数据等动作。
所述步骤S20中，当获取相关充电指令后，获取当前的充电数据，具体地，充电数据包括但不限于充电设备编号、与充电设备编号对应的充电状态参数、充电功率、已充电时间等参数中的至少一种，可以理解，进一步地，充电数据还包括充电***的容量及负载等。本实施例中，根据充电数据对当前充电设备进行排序，根据排序确定功率调降充电设备，进而对功率调降充电设备调降预设功率W 预设，具体是根据某一充电数据的值进行排序，例如根据充电功率的大小进行排序，或者根据充电时间的大小进行排序等。例如，当获取到一个充电指令，排序后，确定排序中第一位的当前充电设备为功率调降充电设备，进而对所述功率调降充电设备调降预设功率W 预设，预设功率W 预设可为3.5kW，但不限于此；同时，控制新接入电动汽车的待充电设备，以预设功率W 预设(即3.5kW)开启充电。可以理解，新接入电动汽车的待充电设备的输出功率由正在充电的当前充电设备的输出功率进行调配，避免造成对充电***负载的冲击。其中，所述步骤S30中，控制待充电设备以预设功率开启充电的步骤，实际是根据所述充电指令触发而执行的操作，该操作并不限定于根据所述充电指令所包含的具体 信息触发；可以理解，所述充电指令中包括用户期望的待充电功率，但在此步骤中，通过充电***调控，控制待充电设备根据接收到的充电指令触发以预设的输出功率开启充电，而不以所述充电指令中的待充电功率开启充电，避免了对充电***造成冲击。
可以理解，所述步骤S20与所述步骤S30，可以设置为先完成步骤S20，对当前充电设备进行调降，再完成步骤S30，对待充电设备进行功率输出；可以理解，在其他实施例中，所述步骤S20与所述步骤S30无先后顺序，两个步骤可以是同时进行的，即，同时对当前充电设备进行调降以及对待充电设备进行功率输出。
其中，根据充电***的实际充电情况不同，所述功率调降充电设备的数量不同，例如接入充电***的待充电设备为一台，则对应的功率调降充电设备的数量为一台，若接入充电***的待充电设备为多台，相应地，功率调降充电设备的数量与待充电设备的数量相同。因此，根据所述第一序列确定功率调降充电设备的数量可以为一台，两台，或多台。
所述步骤S40及步骤S50，定时获取充电***更新的充电数据，具体地，获取更新的充电数据为周期性获取，可以理解，步骤S10中获取的充电数据，包括充电设备编号、与充电设备编号对应的充电状态参数、充电功率等参数，实际是上一周期更新完成的充电数据，但其中，已充电时间根据获取充电数据的当前时间确定。例如，充电***每隔15分钟进行充电数据更新，并相应计算更新负载，其中，充电***的负载包括负载容量L 总、当前负载、剩余负载L 剩余，负载容量L 总表示充电***能够允许的充电功率总量，当前负载表示充电***中正在充电的充电设备的充电功率的总和，剩余负载L 剩余表示充电***当前剩余的功率量，例如充电***的负载容量L 总为200kW，当前负载为80kW，则当前充电***的剩余负载L 剩余为120kW。 进一步，根据负载情况对此次更新前一周期内被调降的功率调降充电设备进行功率调升，使得在周期内被调降功率的充电设备的整体充电效率不至于因充电调控而受到损失，进而避免对用户充电需求造成不利影响。
综上所述，充电***进行周期性的充电负载数据更新及调控，以及基于上述的充电调控方法，对当前充电设备的功率进行调控，避免因新增待充电设备而导致负载超限的情况产生；并且，在周期性更新充电负载数据后，对被调控的充电设备进行恢复性调控，避免充电调控对已有用户的充电过程造成影响；同时保证了充电***的整体稳定以及用户个体的用电需求。
进一步地，请参考图3，所述步骤S20，根据所述充电指令获取当前充电设备的充电数据，根据所述充电数据对所述当前充电设备进行排序，形成第一序列，根据所述第一序列确定功率调降充电设备，控制所述功率调降充电设备调降预设功率W 预设，包括：
步骤S21，获取充电数据，所述充电数据包括与当前充电设备对应的当前充电功率W 原i，i为当前充电设备的序号；
步骤S22，根据所述当前充电功率W 原i对所述当前充电设备排序，形成第一序列；
步骤S23，根据所述第一序列确定所述功率调降充电设备；
步骤S24，调降所述功率调降充电设备的输出功率。
本实施例中，所述充电数据包括对应于当前充电设备的当前充电功率，可以理解，充电数据周期性进行更新，此时的当前充电功率实际即上一周期完成更新时的充电功率，或者，上一周期完成更新以及充电***调控的充电功率。具体地，对当前充电设备排序，形成第一序列，具体是根据充电设备的当前充电功率进行排序而形成；根据充电设备的当前充电功率的 排序进行调降，使得充电***对充电设备的调降更加合理，调降后不至于使得不同充电设备的充电功率的差值过大，充电***整体更加稳定。
具体地，所述步骤S23，根据所述第一序列确定所述功率调降充电设备，包括：根据所述第一序列，确定输出功率最高的当前充电设备为所述功率调降充电设备。例如，第一序列具体排序为：序号/功率，No.3/30kW，No.7/23kW，No.4/19kW，No.5/16kW，No.9/12kW等，No.3充电设备为第一功率调降充电设备。本实施例中，第一序列根据输出功率排序形成，在根据第一序列进行充电调控时，优先从输出功率高的当前充电设备进行调控，使得各当前充电设备的充电功率保持在一定范围，避免了充电***整体负载不稳定。
可以理解，在其他实施例中，确定功率调降充电设备的步骤还可以采用：
根据所述第一序列，确定调降或调升次数不超过预设值，且输出功率最高的当前充电设备为功率调降充电设备；例如，所述预设值为3次，将调降或调升次数不超过三次的当前充电设备进行排序，具体排序为：序号/调降(调升)次数/功率，No.7/1/23kW，No.5/1/16kW，No.9/0/12kW，No.3/3/30kW，No.4/2/19kW等，No.7充电设备为第一功率调降充电设备。
或者，根据所述第一序列，确定在预设时间段内未被调降或未被调升输出功率，且输出功率最高的当前充电设备为功率调降充电设备。例如，具体排序为：序号/是否被调降(调升)/功率，No.7/N/23kW，No.5/N/16kW，No.9/N/12kW，No.3/Y/30kW，No.4/Y/19kW等，No.7充电设备为第一功率调降充电设备。
进一步地，所述步骤S40，获取更新的充电数据，根据所述更新的充电数据确定剩余负载L 剩余，包括：
获取更新的充电数据，所述更新的充电数据包括与充电设备对应的更新充电功率W 更新i及负载容量L 总，根据所述更新充电功率W 更新i及所述负载容量L 总确定剩余负载L 剩余，其中，L 剩余＝L 总-∑W 更新i。所述获取更新的充电数据实际是由充电***对充电数据进行的周期性更新，更新的充电数据主要包括根据步骤S20对当前充电设备调降后及根据步骤S30开启充电后的更新充电功率W 更新i，以及充电***的负载情况，可以理解，此时，更新充电功率W 更新i对应的充电设备包括所述当前充电设备以及所述待充电设备在内的处于充电状态的所有充电设备。其中负载容量L 总是充电***的总容量，通过上述步骤确定充电***的剩余负载L 剩余，亦即确定充电***当前的可用负载，进而可利用其对充电设备进行调控，例如用于调升先前被调降的功率调降充电设备，以及新接入但未以用户请求的充电功率进行充电的待充电设备。
进一步地，请参考图4，所述步骤S50，根据所述剩余负载L 剩余及预设规则控制所述被调降的功率调降充电设备调升输出功率，包括：
步骤S51，根据所述充电数据及所述更新的充电数据，确定所述被调降的功率调降充电设备的预调升功率W 调升i及预调升总功率∑W 调升i；
步骤S52，比较所述剩余负载L 剩余与所述预调升总功率∑W 调升i；
步骤S53，若L 剩余≥∑W 调升i，根据预调升功率W 调升i控制对应所述被调降的功率调降充电设备调升输出功率。
本实施例中，预调升功率W 调升i是对被调降的功率调降充电设备预备调升的功率值，预调升总功率∑W 调升i是所有被调降的功率调降充电设备预调升功率W 调升i的总和。在完成一次周期更新充电数据后，即时计算剩余负载 L 剩余，以及被调降的功率调降充电设备的预调升功率W 调升i及预调升总功率∑W 调升i，比较剩余负载L 剩余及预调升总功率∑W 调升i，即比较当前剩余的功率与预计需要调升的功率，若剩余的功率大于预计需要调升的功率，则根据预调升功率W 调升i给对应的所述被调降的功率调降充电设备调升功率即可，可以理解，在前一周期内，根据待充电设备的接入数量而确定被调降的功率调降充电设备的数量可能为一个、两个或多个；此时，充电***的剩余负载L 剩余大于这些被调降的功率调降充电设备需要调升的输出功率的总量，因此，可对这些被调降的功率调降充电设备的输出功率直接以对应的预调升功率W 调升i进行批量调升。具体地，确定所述被调降的功率调降充电设备的预调升功率W 调升i的步骤，实际为根据对应于所述被调降的功率调降充电设备的充电数据及充电***预设的条件计算得出，具体地，预设的条件可以设定为满足所述被调降的功率调降充电设备的剩余充电时长保持不变的充电需求。可以理解，先对功率调降充电设备的输出功率进行调降，经过一段时间后，此段时间内获取的充电电量实际低于先前设定的充电电量，为了满足在相同剩余充电时长内完成相同充电电量，需要在后续的充电时间内以更高的输出功率进行充电。以此方式控制被调降的功率调降充电设备调升功率，既避免了充电设备的充电效率受到影响，也能使充电***的负载保持稳定。
进一步地，所述充电数据包括当前充电功率W 原i、预约充电电量、已充电电量、第一剩余充电时长T 剩余1及第一已充电时长T 1，所述
Figure PCTCN2019113604-appb-000001
Figure PCTCN2019113604-appb-000002
所述更新的充电数据包括更新充电功率W 更新i及第二已充电时长T 2；其中，对于被调降的功率调降充电设备而言，W 更新i＝W 原i-W 预设；所述预调升功率
Figure PCTCN2019113604-appb-000003
本实施例中，此时，充电***处于周期性更新充电数据的其中一个周期内，可以理解，所述充电数据包括对应于当前充电设备相关的充电数据，具体包括但不限于充电指令、充电起始时间、当前时间、已充电时长、当前输出功率、已充电电量、第一剩余充电时长T 剩余1中的至少一种，充电指令具体包括预约充电电量。其中，根据预约充电电量及已充电电量可确定剩余充电电量，第一剩余充电时长T 剩余1是当前充电设备根据当前输出功率完成剩余充电电量充电所需要的持续时长，第一已充电时长T 1是充电设备当前已经充电的时长。为满足第一剩余充电时长T 剩余1完成充电的需求，计算因功率调降而需调升的具体功率，即预调升功率W 调升i，以满足用户的充电效率不受充电***调控的影响，亦即，功率调降充电设备在调控前的剩余充电时长不因调控而变化，以保证用户的充电体验。
进一步地，所述步骤S52，比较所述剩余负载L 剩余及所述预调升总功率∑W 调升i之后，还包括：
步骤S54，若L 剩余<∑W 调升i，根据所述更新的充电数据，或根据所述充电数据及所述更新的充电数据对所述被调降的功率调降充电设备进行排序，形成第二序列，根据所述第二序列依序控制被调降的功率调降充电设备调升对应的预调升功率W 调升i并依次更新剩余负载L 剩余′，直至在调升其中一个被调降的功率调降充电设备时，更新的剩余负载L 剩余′小于对应的预调升功率W 调升i′，控制所述其中一个被调降的功率调降充电设备调升功率L 剩余′。
本实施例中，比较剩余负载L 剩余及预调升总功率∑W 调升i，即比较当前 剩余的负载与预计需要调升的功率，若充电***剩余负载L 剩余，即可用功率小于预调升总功率∑W 调升i，不能直接对所述被调降的功率调降充电设备进行批量调升，而需进一步地对所述被调降的功率调降充电设备进行第二次排序，再依次对所述被调降的功率调降充电设备的功率进行调升，在充电***负载允许的前提下，满足用户的充电体验。具体地，例如，当前剩余负载L 剩余为20kW，但在此前一周期中，加入的待充电设备为8台，对应的被调降的功率调降充电设备也为8台，根据前述实施例描述的计算确定了对应于各被调降的功率调降充电设备的预调升功率，并根据相应的排序规则形成第二序列：No.7/4.5kW、No.13/3.8kW、No.3/5kW、No.9/3.6kW、No.18/4kW、No.23/3.8kW、No.5/4kW、No.1/3.9kW，根据第二序列依次控制被调降的功率调降充电设备调升功率，先控制No.7充电设备调升功率4.5kW，调升完成后剩余负载由20kW更新为15.5kW，接下来控制No.13充电设备调升3.8kW，调升完成后剩余负载由15.5kW更新为11.7kW，以此类推，当依序控制完成对No.9充电设备的调升时，剩余负载更新为3.1kW，其小于No.18充电设备的预调升功率，因此控制No.18充电设备调升3.1kW，停止调升。
进一步地，所述第二序列具体为：根据所述被调降的功率调降充电设备的第二剩余充电时长T 剩余2进行排序，由所述第二序列中所述第二充电剩余充电时长T 剩余2最小的被调降的功率调降充电设备开始调升输出功率；所述充电数据包括当前充电功率W 原i、预约充电电量、已充电电量、第一剩余充电时长T 剩余1及第一已充电时长T 1，所述更新的充电数据包括第二已充电时长T 2，所述
Figure PCTCN2019113604-appb-000004
所述第二剩余充电时长T 剩余2＝T 剩余1-T 2+T 1。其中，第一剩余充电时长T 剩余1是调控前所确定的预计充电时长，具体是当前充电设备根据当前输出功率完 成剩余充电电量充电所需要的持续时长，所述第二剩余充电时长T 剩余2是根据所述第一剩余充电时长T 剩余1及调降时长确定，是在对功率调降充电设备进行调升时的预计剩余充电时长。本实施例中，以剩余充电时长作为参考因素，能够保证优先满足剩余充电时间较短的用户的充电需求。
本实施例中，此时，充电***处于完成一次周期性更新充电数据后的时间，所述第二已充电时长T 2为充电设备此时的已充电的时长，其中，所述第一已充电时长T 1是一个更新周期内的某一时刻，所述第二已充电时长T 2是该更新周期结束，完成新一次更新的时刻，因此，T 2>T 1。
可以理解，所述第二序列还可以具体为：根据所述被调降的功率调降充电设备的调降时长T 调降进行排序，由所述第二序列中所述调降时长T 调降最大的被调降的功率调降充电设备开始调升输出功率；所述充电数据包括第一已充电时长T 1，所述更新的充电数据包括第二已充电时长T 2，所述调降时长T 调降＝T 2-T 1。本实施例中，以调降充电时长作为参考因素，优先恢复被调降充电时间较长的功率调降充电设备的充电功率，优先满足相应用户的充电需求。
进一步地，在所述步骤S53，若L 剩余≥∑W 调升i，根据预调升功率W 调升i控制对应所述被调降的功率调降充电设备调升输出功率之后，还包括：
步骤S55，根据所述剩余负载L 剩余、所述预调升总功率∑W 调升i及所述充电指令控制所述待充电设备调升输出功率。
本实施例中，在利用剩余负载L 剩余对被调降的功率调降充电设备进行功率调升后，再对接入的待充电设备进行功率调升，进一步提高充电***在保持负载稳定前提下的充电效率。
进一步地，请参考图5，所述充电指令包括待充电设备的待充电功率 W 待j，j为所述待充电设备的序号，所述步骤55，根据所述剩余负载L 剩余、所述预调升总功率∑W 调升i及所述充电指令控制所述待充电设备调升输出功率，包括：
步骤S551，根据所述更新的充电数据，或根据所述充电数据及所述更新的充电数据，对所述待充电设备进行排序，形成第三序列，并且，根据所述剩余负载L 剩余及所述预调升总功率∑W 调升i确定空闲调升功率W 空闲j，所述W 空闲j＝L 剩余-∑W 调升i；
步骤S552，根据所述第三序列依序控制待充电设备调升至对应的待充电功率W 待j并依次更新空闲调升功率W 空闲j′；直至在调升其中一个待充电设备时，更新的空闲调升功率W 空闲j′小于对应的待调升功率W 待调j′，其中W 待调j′＝W 待j′-W 预设，控制所述其中一个待充电设备调升功率W 空闲j′，停止调升；或者，直至控制所述第三序列所有待充电设备完成功率调升，停止调升。
本实施例中，将待调升功率与空闲调升功率进行比较，实现对待充电设备的充电调控。所述待充电设备，是在一个更新周期内接入充电***的充电设备，可以理解，其数量可以为一台、两台或多台，对应地，在前述的充电调控中，对当前充电设备的功率调降是根据待充电设备的充电指令而触发，所以待充电设备的数量与前述的被调降的功率调降充电设备的数量是相对应的。
其中，所述充电指令即所述步骤S10中，由待充电设备发送的充电指令，可以理解，充电指令还具体包括待充电功率W 待j，即用户请求的充电输出功率。待充电设备在前述的充电调控中以预设功率W 预设开启充电，并未以充电指令中的充电输出功率开启充电，因此，在完成对被调降设备进 行功率调升后，根据充电***的负载情况对待充电设备的功率进行对应调升，避免直接以待充电功率W 待j开启充电对充电***造成负载冲击的情况。具体地，在完成对被调降的功率调降充电设备的调升后，进行新接入待充电设备的调升，并对新接入的待充电设备进行排序依次调升，提高充电负载利用以及降低电网冲击。具体对应于先前示例，如调升前的空闲调升功率W 空闲1为16.5kW，其中一待充电设备1的待充电功率W 待1为10kW，即应将待充电设备1的功率调升至待充电功率W 待110kW，待充电设备1先前以预设功率W 预设3.5kW开启充电，因此，对待充电设备1的调升功率为待充电功率与预设功率的差值，具体为6.5kW，调升后空闲调升功率W 空闲2更新为10kW。
可以理解，在对所述第三序列中待充电设备j进行功率调升时，对应于待充电设备j的空闲调升功率为W 空闲j，若W 空闲j能够满足对待充电设备j以待充电功率充电的调升功率值，即对待充电设备j进行功率调升；此时，对第三序列中待充电设备j的功率调升完成，接下来对第三序列中待充电设备j+1进行功率调升，对应地，此时空闲调升功率更新为W 空闲j+1，再根据如前述相同的方式进行比较及功率调升操作。
本实施例中，对新接入的待充电设备的功率调升，是依次进行的，调升所述其中一待充电设备1后，更新空闲调升功率W 空闲2，再进行另一待充电设备2的调升，确保充电***的负载稳定。对应于先前示例，如所述另一待充电设备2的待充电功率W 待2为11.5kW，该另一待充电设备2先前以预设功率W 预设3.5kW开启充电，即调升功率为8kW，前一次调升后更新空闲调升功率W 空闲2为10kW，大于调升该另一待充电设备2的调升功率8kW，可满足对待充电设备2的调升，此时以待充电功率W 待211.5kW为充电设备 2进行充电。
进一步地，针对所述第三序列中相邻两个待充电设备的空闲调升功率满足公式：W 空闲j+1＝W 空闲j-W 待j+W 预设。
本实施例中，在对待充电设备的调升控制过程中，当空闲调升功率W 空闲j无法满足待充电设备j的充电需求时，控制待充电设备j进行调升，调升的功率值为空闲调升功率W 空闲j。对应于先前示例，在进行多次调升后，空闲调升功率更新为W 空闲3，由空闲调升功率W 空闲116.5kW依次更新为空闲调升功率W 空闲210kW和空闲调升功率W 空闲32kW，可以理解，在下一次的调升中，待充电设备3先前以预设功率W 预设3.5kW开启充电，若待充电功率W 待3大于5.5kW，即调升功率大于2kW，则此时空闲调升功率W 空闲3无法满足充电指令中的待充电功率，此时，以空闲调升功率W 空闲32kW进行调升，控制待充电设备3的输出功率调升2kW，以5.5kW的功率进行充电。可以理解，若在第一次调升时，空闲调升功率即不满足待充电设备的调升需求，则直接根据空闲调升功率对对应的待充电设备进行功率调升，调升结束。
进一步地，所述更新的充电数据包括第二已充电时长T 2，所述第三序列为根据第二已充电时长T 2对所述待充电设备进行排序形成，所述比较所述空闲调升功率W 空闲j与所述第三序列中待充电设备的所述待充电功率W 待j，包括：比较所述空闲调升功率W 空闲j与所述第三序列中第二已充电时长T 2最大的待充电设备的所述待调升功率W 待调j，其中W 待调j＝W 待j-W 预设。
请参考图6，本发明实施例还提供了一种充电调控装置100，所述充电调控装置100设置于充电***200中，接入外部电网，获取充电***200 的电力数据。可以理解，所述充电调控装置100还可以设置为与所述充电云平台201连接，通过所述充电云平台201获取充电数据，以及向充电设备等传送指令，例如开启充电、调升/调降充电功率等。
所述充电调控装置100包括：
接收单元10，用于接收待充电设备的充电指令；以及，
处理控制单元20，用于根据所述充电指令获取当前充电设备的充电数据，根据所述充电数据对所述当前充电设备进行排序，形成第一序列，根据所述第一序列确定功率调降充电设备，控制所述功率调降充电设备调降预设功率W 预设；并且，用于根据所述充电指令触发控制所述待充电设备以所述预设功率W 预设开启充电；
所述处理控制单元20，还用于获取更新的充电数据，根据所述更新的充电数据确定剩余负载L 剩余；
所述处理控制单元20，还用于根据所述剩余负载L 剩余及预设规则控制被调降的功率调降充电设备调升输出功率。
本实施例中，所述充电调控装置应用于充电***，所述充电指令为电动汽车提出充电需求的充电指令，具体包括充电开启时间、充电时间、充电需求电量、充电功率等数据中的至少一种数据。所述充电指令具体可由充电设备202发出或者通过用户移动终端204发出，用户通过充电设备202设置相关充电参数形成所述充电指令，或者通过移动终端204设定相关充电参数形成所述充电指令。
当所述充电调控装置100的接收单元10获取相关充电指令后，由处理控制单元20获取当前的充电数据，根据充电数据对当前充电设备进行排序，根据排序确定功率调降充电设备，进而对功率调降充电设备调降预设功率 W 预设，具体是根据某一充电数据的值进行排序，例如根据充电功率的大小进行排序，或者根据充电时间的大小进行排序等。例如，当获取到一个充电指令，排序后，确定排序中第一位的当前充电设备为功率调降充电设备，进而对所述功率调降充电设备调降预设功率W 预设，预设功率W 预设可为3.5kW，但不限于此；同时，控制新接入电动汽车的待充电设备以预设功率W 预设(即3.5kW)开启充电。可以理解，新接入电动汽车的待充电设备的输出功率由正在充电的当前充电设备的功率进行调配，避免造成对充电***负载的冲击。其中，控制待充电设备以预设功率开启充电，实际是根据所述充电指令触发而执行的操作，该操作并不限定于根据所述充电指令所包含的具体信息触发；可以理解，所述充电指令中包括用户期望的待充电功率，但在此，通过充电***调控，控制待充电设备根据接收到的充电指令触发以预设的输出功率开启充电，而不以所述充电指令中的待充电功率开启充电，避免了对充电***造成冲击。
可以理解，所述对当前充电设备的调降以及对待充电设备的调升，两者的顺序不受限制，可以先进行对当前充电设备的调降再进行对待充电设备的调升，或者，同时进行对当前充电设备的调降以及对待充电设备的调升。
其中，根据充电***的实际充电需求，所述功率调降充电设备的数量不同，例如接入充电***的待充电设备为一台，则对应的功率调降充电设备的数量为一台，若接入充电***的待充电设备为多台，相应地，功率调降充电设备的数量与待充电设备的数量相同。因此，根据所述第一序列确定功率调降充电设备的数量可以为一台，两台，或多台。
进而，处理控制单元20定时获取充电***更新的充电数据，具体地，获取更新的充电数据为周期性获取，可以理解，获取的充电数据，包括充 电设备编号、与充电设备编号对应的充电状态参数、充电功率等参数，实际是上一周期更新完成的充电数据，但其中，已充电时间根据获取充电数据的当前时间确定。例如，充电***每隔15分钟进行充电数据更新，相应计算更新负载，其中，充电***的负载包括负载容量L 总、当前负载、剩余负载L 剩余，负载容量L 总表示充电***能够允许的充电功率总量，当前负载表示充电***中正在充电的充电设备的充电功率的总和，剩余负载L 剩余表示充电***当前剩余的功率量，例如充电***的负载容量L 总为200kW，当前负载为80kW，则当前充电***的剩余负载L 剩余为120kW。进一步，根据负载情况对周期内被调降的功率调降充电设备进行功率调升，使得在周期内被调降功率的充电设备的整体充电效率不至于因充电调控而受到损失，对用户充电需求造成不利影响。
综上所述，充电***进行周期性的充电负载数据更新及调控，以及基于上述的充电调控方法，对当前充电设备的功率进行调控，避免因新增待充电设备而导致负载超限的情况产生；并且，在周期性更新充电负载数据后，对被调控的充电设备进行恢复性调控，避免充电调控对已有用户的充电过程造成影响；同时保证了充电***的整体稳定以及用户的用电需求。
进一步地，请参考图7，所述处理控制单元20，包括：
数据获取子单元21，用于获取充电数据，所述充电数据包括与当前充电设备对应的当前充电功率W 原i，i为当前充电设备的序号；
排序子单元22，用于根据所述当前充电功率W 原i对所述当前充电设备排序，形成第一序列；
处理子单元23，还用于根据所述第一序列确定所述功率调降充电设备；以及，
控制子单元24，用于控制所述功率调降充电设备调降所述预设功率W 预设。
本实施例中，所述充电数据包括对应于当前充电设备的当前充电功率，可以理解，充电数据周期性进行更新，此时的当前充电功率实际为上一周期完成更新时的充电功率，或者，上一周期完成更新以及充电***调控的充电功率。具体地，对当前充电设备进行排序，形成第一序列，具体是根据当前充电设备的当前充电功率进行排序而形成；根据充电设备的当前充电功率的排序进行调降，使得充电***对充电设备的调降更加合理，调降后不至于使得不同充电设备的充电功率的差值过大，充电***整体更加稳定。
进一步地，所述处理子单元23，进一步用于：
根据所述第一序列，确定输出功率最高的当前充电设备为所述功率调降充电设备。例如，第一序列具体排序为：序号/功率，No.3/30kW，No.7/23kW，No.4/19kW，No.5/16kW，No.9/12kW等，No.3充电设备为第一功率调降充电设备。本实施例中，第一序列根据输出功率排序形成，在根据第一序列进行充电调控时，优先从输出功率高的当前充电设备进行调控，使得各当前充电设备的充电功率保持在一定范围，避免了充电***整体负载不稳定。
可以理解，在其他实施例中，所述处理子单元23还可以设置为，用于根据所述第一序列，确定调降或调升次数不超过预设值，且输出功率最高的当前充电设备为功率调降充电设备；例如，所述预设值为3次，将调降或调升次数不超过三次的当前充电设备进行排序，具体排序为：序号/调降(调升)次数/功率，No.7/1/23kW，No.5/1/16kW，No.9/0/12kW，No.3/3/30kW，No.4/2/19kW等，No.7充电设备为第一功率调降充电设备。
或者，根据所述第一序列，确定在预设时间段内未被调降或未被调升 输出功率，且输出功率最高的当前充电设备为功率调降充电设备。例如，具体排序为：序号/是否被调降(调升)/功率，No.7/N/23kW，No.5/N/16kW，No.9/N/12kW，No.3/Y/30kW，No.4/Y/19kW等，No.7充电设备为第一功率调降充电设备。
进一步地，所述处理控制单元20，包括：
数据获取子单元25，用于获取更新的充电数据，所述更新的充电数据包括与充电设备对应的更新充电功率W 更新i及负载容量L 总；以及，
处理子单元23，用于根据所述更新充电功率W 更新i及所述负载容量L 总确定剩余负载L 剩余，其中，L 剩余＝L 总-∑W 更新i。
本实施例中，所述获取更新的充电数据实际是由充电***对充电数据进行的周期性更新，更新的充电数据主要包括根据对当前充电设备调降后及开启待充电设备充电后的更新充电功率W 更新i，以及充电***的负载情况，可以理解，此时，更新充电功率W 更新i对应的充电设备包括所述当前充电设备以及所述待充电设备在内的处于充电状态的所有充电设备。其中负载容量L 总是充电***的总容量。通过上述确定的充电***的剩余负载L 剩余，亦即确定充电***当前的可用负载，进而可利用其对充电设备进行调控，例如用于调升先前被调降的功率调降充电设备，以及新接入但未以用户请求的充电功率进行充电的待充电设备。
进一步地，所述处理子单元23，进一步用于根据所述充电数据及所述更新的充电数据，确定所述被调降的功率调降充电设备的预调升功率W 调升i及预调升总功率∑W 调升i；比较所述剩余负载L 剩余与所述预调升总功率∑W 调升i；
所述控制子单元24，还用于当确定L 剩余≥∑W 调升i，根据预调升功率 W 调升i控制对应所述被调降的功率调降充电设备调升输出功率。
本实施例中，预调升功率W 调升i是对被调降的功率调降充电设备预备调升的功率值，预调升总功率∑W 调升i是所有被调降的功率调降充电设备预调升功率W 调升i的总和。在完成一次周期更新充电数据后，即时计算剩余负载L 剩余，以及被调降的功率调降充电设备的预调升功率W 调升i及预调升总功率∑W 调升i，比较剩余负载L 剩余及预调升总功率∑W 调升i，即比较充电***当前剩余的可用功率与预计需要调升的总功率，若剩余的可用功率大于预计需要调升的功率，则根据预调升功率W 调升i给对应的所述被调降的功率调降充电设备调升功率即可，可以理解，在前一周期内，根据待充电设备的接入数量而确定被调降的功率调降充电设备的数量可能为一个、两个或多个；此时，充电***的剩余负载L 剩余大于这些被调降的功率调降充电设备需要调升的输出功率的总量，因此，可对这些被调降的功率调降充电设备的输出功率直接以对应的预调升功率W 调升i进行批量调升。具体地，确定所述被调降的功率调降充电设备的预调升功率W 调升i，实际为根据对应于所述被调降的功率调降充电设备的充电数据及充电***预设的条件计算得出，具体地，预设的条件可以设定为满足所述被调降的功率调降充电设备的剩余充电时长保持不变的充电需求。可以理解，先对功率调降充电设备的输出功率进行调降，经过一段时间后，此段时间内获取的充电电量实际低于原设定的充电电量，为了满足在相同剩余时长内完成相同电量，需要在后续的充电时间内以更高的输出功率进行充电。以此方式控制被调降的功率调降充电设备调升功率，既避免了充电设备的充电效率受到影响，也能使充电***的负载保持稳定。
进一步地，所述充电数据包括当前充电功率W 原i、预约充电电量、已 充电电量、第一剩余充电时长T 剩余1及第一已充电时长T 1，所述
Figure PCTCN2019113604-appb-000005
Figure PCTCN2019113604-appb-000006
所述更新的充电数据包括更新充电功率W 更新i及第二已充电时长T 2；其中，对于被调降的功率调降充电设备而言，W 更新i＝W 原i-W 预设；所述预调升功率
Figure PCTCN2019113604-appb-000007
本实施例中，此时，充电***处于周期性更新充电数据的其中一个周期内，可以理解，所述充电数据包括对应于当前充电设备相关的充电数据，具体包括但不限于充电指令、充电起始时间、当前时间、已充电时长、当前输出功率、已充电电量、第一剩余充电时长T 剩余1中的至少一种，充电指令具体包括预约充电电量。其中，根据预约充电电量及已充电电量可确定剩余充电电量，第一剩余充电时长T 剩余1是当前充电设备在根据当前输出功率完成剩余充电电量充电所需要的持续时长，第一已充电时长T 1是当前充电设备当前已经充电的时长。为满足第一剩余充电时长T 总剩余1完成充电的需求，计算因功率调降而需调升的功率值，即预调升功率W 调升i，以满足用户的充电效率不受充电***调控的影响，亦即，功率调降充电设备在调控前的剩余充电时长不因调控而变化，以保证用户的充电体验。
进一步地，所述排序子单元22，还用于当确定L 剩余<∑W 调升i，根据所述更新的充电数据，或根据所述充电数据及所述更新的充电数据对所述被调降的功率调降充电设备进行排序，形成第二序列；
所述控制子单元，还用于根据所述第二序列依序控制被调降的功率调降充电设备调升对应的预调升功率W 调升i并依次更新剩余负载L 剩余′，直至在调升其中一个被调降的功率调降充电设备时，更新的剩余负载L 剩余′小于 对应的预调升功率W 调升i′，控制所述其中一个被调降的功率调降充电设备调升功率L 剩余′。
本实施例中，比较剩余负载L 剩余及预调升总功率∑W 调升i，即比较当前剩余的负载与预计需要调升的功率，若充电***剩余负载L 剩余，即可用功率小于预调升总功率∑W 调升i，不能直接对所述被调降的功率调降充电设备进行批量调升，而需进一步地对所述被调降的功率调降充电设备进行第二次排序，再依次对排序的所述被调降的功率调降充电设备的功率进行调升，在充电***负载允许的前提下，满足用户的充电需求。具体地，例如，当前剩余负载L 剩余为20kW，但在此前一周期中，加入的待充电设备为8台，对应的被调降的功率调降充电设备也为8台，根据前述实施例描述的计算确定了对应于各被调降的功率调降充电设备的预调升功率，并根据相应的排序规则形成第二序列：No.7/4.5kW、No.13/3.8kW、No.3/5kW、No.9/3.6kW、No.18/4kW、No.23/3.8kW、No.5/4kW、No.1/3.9kW，根据第二序列依次控制被调降的功率调降充电设备调升功率，先控制No.7充电设备调升功率4.5kW，调升完成后剩余负载由20kW更新为15.5kW，接下来控制No.13充电设备调升3.8kW，调升完成后剩余负载由15.5kW更新为11.7kW，以此类推，当依序控制完成对No.9充电设备的调升时，剩余负载更新为3.1kW，其小于No.18充电设备的预调升功率，因此控制No.18充电设备调升3.1kW，停止调升。进一步地，所述排序子单元22，进一步用于根据所述被调降的功率调降充电设备的第二剩余充电时长T 剩余2进行排序，形成所述第二序列；所述控制子单元，进一步用于控制由所述第二序列中所述第二充电剩余充电时长T 剩余2最小的被调降的功率调降充电设备开始调升输出功率；所述充电数据包括当前充电功率W 原i、预约充电电量、已充电电量、第一剩余充电时长T 剩余1及第一已充电时长T 1，所述更新的充电数据包括第二已充电时 长T 2，所述
Figure PCTCN2019113604-appb-000008
所述第二剩余充电时长T 剩余2＝T 剩余1-T 2+T 1。其中，第一剩余充电时长T 剩余1是调控前所确定的预计充电时长，具体是当前充电设备根据当前输出功率完成剩余充电电量充电所需要的持续时长，所述第二剩余充电时长T 剩余2是根据所述第一剩余充电时长T 剩余1及调降时长确定，是在对功率调降充电设备进行调升时的预计剩余充电时长。本实施例中，以剩余充电时长作为参考因素，能够保证优先满足剩余充电时间较短的用户的充电需求。
本实施例中，此时，充电***处于完成一次周期性更新充电数据后的时间，所述第二已充电时长T 2为充电设备此时的已充电的时长，其中，所述第一已充电时长T 1是一个更新周期内的某一时刻，所述第二已充电时长T 2是该更新周期结束并完成新一次更新的时刻，因此，T 2>T 1。
可以理解，另一实施例中，所述排序子单元22，还用于根据所述被调降的功率调降充电设备的调降时长T 调降进行排序，形成所述第二序列；所述控制子单元，进一步用于控制由所述第二序列中所述调降时长T 调降最大的被调降的功率调降充电设备开始调升输出功率；所述充电数据包括第一已充电时长T 1，所述更新的充电数据包括第二已充电时长T 2，所述调降时长T 调降＝T 2-T 1。本实施例中，以调降充电时长作为参考因素，优先恢复被调降充电时间较长的功率调降充电设备的充电功率，优先满足相应用户的充电需求。
进一步地，所述控制子单元24，还用于根据所述剩余负载L 剩余、所述预调升总功率∑W 调升i及所述充电指令控制所述待充电设备调升输出功率。
本实施例中，在利用剩余负载L 剩余对被调降的功率调降充电设备进行功率调升后，再对接入的待充电设备进行功率调升，进一步提高充电*** 在保持负载稳定前提下的充电效率。
进一步地，所述充电指令包括待充电设备的待充电功率W 待j，j为所述待充电设备的序号；
所述排序子单元22，还用于根据所述更新的充电数据，或根据所述充电数据及所述更新的充电数据，对所述待充电设备进行排序，形成第三序列；
所述处理子单元23，还用于根据所述剩余负载L 剩余及所述预调升总功率∑W 调升i确定空闲调升功率W 空闲j，所述W 空闲j＝L 剩余-∑W 调升i；
所述控制子单元24还用于根据所述第三序列依序控制待充电设备调升至对应的待充电功率W 待j并依次更新空闲调升功率W 空闲j′；直至在调升其中一个待充电设备时，更新的空闲调升功率W 空闲j′小于对应的待调升功率W 待调j′，其中W 待调j′＝W 待j′-W 预设，控制所述其中一个待充电设备调升功率W 空闲j′，停止调升；或者，直至控制所述第三序列所有待充电设备完成功率调升，停止调升。
本实施例中，将待调升功率与空闲调升功率进行比较，实现对待充电设备的充电调控。所述待充电设备，是在一个更新周期内接入充电***的充电设备，可以理解，其数量可以为一台、两台或多台，相应的，前述的充电调控，对当前充电设备的功率调降是根据待充电设备的充电指令而触发，所以待充电设备的数量与前述的被调降的功率调降充电设备的数量是相对应的。
其中，所述充电指令即所述接受单元10接收的由待充电设备发送的充电指令，可以理解，充电指令还具体包括待充电功率W 待j，即用户请求的充电输出功率。待充电设备在前述的充电调控中以预设功率W 预设开启充电， 并未以充电指令中的需求功率开启，因此，在完成对被调降设备进行功率调升后，对待充电设备的功率进行对应调升，避免直接以待充电功率W 待j开启充电对充电***造成负载冲击的情况。具体地，在完成对被调降的功率调降充电设备的调升后，进行新接入待充电设备的调升，并对新接入的待充电设备进行排序依次调升，提高充电负载利用以及降低电网冲击。具体对应于先前示例，如调升前的空闲调升功率W 空闲1为16.5kW，其中一待充电设备1的待充电功率W 待1为10kW，即应将待充电设备1的功率调升至待充电功率W 待110kW，待充电设备1先前以预设功率W 预设3.5kW开启充电，因此，对待充电设备1的调升功率为待充电功率与预设功率的差值，具体为6.5kW，调升后空闲调升功率W 空闲2更新为10kW。
可以理解，在对所述第三序列中待充电设备j进行功率调升时，对应于待充电设备j的空闲调升功率为W 空闲j，若W 空闲j能够满足对待充电设备j以待充电功率充电的调升功率值，即对待充电设备j进行功率调升；此时，对第三序列中待充电设备j的功率调升完成，接下来对第三序列中待充电设备j+1进行功率调升，对应地，此时空闲调升功率更新为W 空闲j+1，再根据如前述相同的方式进行比较及功率调升操作。
本实施例中，对新接入的待充电设备的功率调升，是依次进行的，调升所述其中一待充电设备1后，更新空闲调升功率W 空闲2，再进行另一待充电设备2的调升，确保充电***的负载稳定。对应于先前示例，如所述另一待充电设备2的待充电功率W 待2为11.5kW，该另一待充电设备2先前以预设功率W 预设3.5kW开启充电，即调升功率为8kW，前一次调升后更新空闲调升功率W 空闲2为10kW，大于调升该另一待充电设备2的调升功率8kW，可满足对待充电设备2的调升，此时以待充电功率W 待211.5kW为充电设备 2进行充电。
进一步地，针对所述第三序列中相邻两个待充电设备的空闲调升功率满足公式：W 空闲j+1＝W 空闲j-W 待j+W 预设。
本实施例中，在对待充电设备的调升控制过程中，当空闲调升功率W 空闲j无法满足待充电设备j的充电需求时，控制待充电设备j进行调升，调升的功率值为空闲调升功率W 空闲j。对应于先前示例，在进行多次调升后，空闲调升功率更新为W 空闲3，由空闲调升功率W 空闲116.5kW依次更新为空闲调升功率W 空闲210kW和空闲调升功率W 空闲32kW，可以理解，在下一次的调升中，待充电设备3先前以预设功率W 预设3.5kW开启充电，若待充电功率W 待3大于5.5kW，即调升功率大于2kW，则此时空闲调升功率W 空闲3无法满足充电指令中的待充电功率，此时，以空闲调升功率W 空闲32kW进行调升，控制待充电设备3的输出功率调升2kW，以5.5kW的功率进行充电。可以理解，若在第一次调升时，空闲调升功率即不满足待充电设备的调升需求，则直接根据空闲调升功率对对应的待充电设备进行功率调升，调升结束。
进一步地，所述更新的充电数据包括第二已充电时长T 2，所述排序子单元22，具体用于根据第二已充电时长T 2对所述待充电设备进行排序形成所述第三序列，所述处理子单元，进一步用于比较所述空闲调升功率W 空闲j与所述第三序列中第二已充电时长T 2最大的待充电设备的所述待调升功率W 待调j，其中W 待调j＝W 待j-W 预设。
本发明提供的充电调控方法及装置，在待充电设备接入***时，先以预设输出功率进行充电，同时，对当前充电设备进行相应功率的调降，避免因不确定数量的待充电设备接入时对充电***的负载造成冲击而导致设 备损坏；之后在周期性获取充电负载数据时，根据实际负载情况，将剩余的负载调配给被调降的当前充电设备，使得使得充电***的整体负载能够保持在安全的范围内，保持充电***的稳定
可以理解，在另一实施例中，所述充电调控方法，在对充电设备的调控中，根据输出的电流作为调控参数执行，具体地，所述充电调控方法，包括：
接收待充电设备的充电指令；
根据所述充电指令获取当前充电设备的充电数据，根据所述充电数据对所述当前充电设备进行排序，形成第一序列，根据所述第一序列确定电流调降充电设备，控制所述电流调降充电设备调降预设电流I 预设；并且，根据所述充电指令触发控制所述待充电设备以所述预设电流I 预设开启充电；
获取更新的充电数据，根据所述更新的充电数据确定剩余电流I 剩余；以及，
根据所述剩余电流I 剩余及预设规则控制被调降的电流调降充电设备调升输出电流。
本实施例中，所述充电调控方法与前述实施例中的不同之处在于，所述充电***的容量参数(剩余负载/剩余电流)及调控参数(调升/调降功率、调升/调降电流)由功率改为电流。具体地，例如，充电***的变压器电流上限为300A，当前充电状态下的电流为180A，则剩余电流为120A。
相应地，前述的其他实施例中，将对应容量参数及调控参数由功率改为电流后，同样可以实施，在此不再赘述。
