本发明实施例提供一种充电系统。图1为本发明实施例提供的充电系统的结构图。该充电系统适用于给频繁运行的无人飞行器或可移动机器人的多块电池同时充电，在给多块电池充电的同时，该充电系统还可以给无人飞行器或可移动机器人的的外部设备例如遥控设备、拍摄设备等设备进行充电。如图1所示，充电系统包括：至少一个充电电路、第一充电接口111、一个或多个处理器112、以及适配器113；如图1所示，至少一个充电电路包括充电电路1、充电电路2、充电电路3、充电电路4，此处只是示意性说明，并不限定充电电路的个数。其中，每个充电电路用于给至少一个电池充电；如图1所示，充电电路1用于给电池B1和电池B2充电，充电电路2用于给电池B3和电池B4充电，充电电路3用于给电池B5和电池B6充电，充电电路4用于给电池B7和电池B8充电，在本实施例中，每个充电电路可以给两个电池充电，此处只是示意性说明，并不限定每个充电电路可以充电的电池的个数。
可选的，每个电池通过一个第一开关与给所述电池充电的充电电路电连接。所述处理器控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电时，具体用于：控制与所述充电电路连接的至少一个第一开关闭合，以使所述充电电路给与所述充电电路连接的至少一个电池充电。如图1所示，电池B1通过开关S1与充电电路1电连接，电池B2通过开关S2与充电电路1电连接；电池B3通过开关S3与充电电路2电连接，电池B4通过开关S4与充电电路2电连接；电池B5通过开关S5与充电电路3电连接，电池B6通过开关S6与充电电路3电连接；电池B7通过开关S7与充电电路4电连接，电池B8通过开关S8与充电电路4电连接。处理器112通过控制开关S1闭合，以使充电电路1给电池B1充电；或者通过控制开关S2闭合，以使充电电路1给电池B2充电；或者通过控制开关S3闭合，以使充电电路2给电池B3充电；或者通过控制开关S4闭合，以使充电电路2给电池B4充电；或者通过控制开关S5闭合，以使充电电路3给电池B5充电；或者通过控制开关S6闭合，以使充电电路3给电池B6充电；或者通过控制开关S7闭合，以使充电电路4给电池B7充电；或者通过控制开关S8闭合，以使充电电路4给电池B8充电。开关S1-S8具体可以是机械的继电器或者半导体的背靠背的P沟道金属氧化物半导体场效应晶体管(positive channel Metal Oxide Semiconductor，简称PMOS)。
第一充电接口111与所述每个充电电路电连接，用于给第一外部设备充电。如图1所示，第一充电接口111分别与充电电路1、充电电路2、充电电路3、充电电路4电连接，可选的，每个充电电路通过一个第一单向导通器件与第一充电接口111电连接。所述第一单向导通器件的输入端与所述充电电路电连接，所述第一单向导通器件的输出端与所述第一充电接口电连接。此处的第一单向导通器件包括：二极管。如图1所示，充电电路1通过二极管D9与第一充电接口111电连接；充电电路2通过二极管D10与第一充电接口111电连接；充电电路3通过二极管D11与第一充电接口111电连接；充电电路4通过二极管D12与第一充电接口111电连接。二极管D9的输入端与充电电路1电连接，二极管D9的输出端与第一充电接口111电连接；二极管D10的输入端与充电电路2电连接， 二极管D10的输出端与第一充电接口111电连接；二极管D11的输入端与充电电路3电连接，二极管D11的输出端与第一充电接口111电连接；二极管D12的输入端与充电电路4电连接，二极管D12的输出端与第一充电接口111电连接。
在本实施例中，第一外部设备包括如下至少一种：无人机的遥控设备、拍摄设备。该拍摄设备可以是搭载在无人飞行器上的拍摄设备。电池B1-B8中的一个或多个可以是无人飞行器的动力电源，当无人飞行器的电池电量下降到一定程度时，需要给无人飞行器的电池进行充电，在给电池充电的同时，该充电系统还可以给无人飞行器的外部设备进行充电。
如图1所示，交流电源为110V～220V的交流电，交流电源经过交流转直流AC/DC适配器113后转换为30V的直流电源，输出电流为27A，标称输出功率为800W。在本实施例中，充电电路1、充电电路2、充电电路3、充电电路4具体可以是4路直流充电电路，在其他实施例中，充电电路1、充电电路2、充电电路3、充电电路4还可以是4路直流充电器。适配器113输出的30V直流电被4路直流充电电路分别以先恒流后恒压的方式降压给电池，以对电池进行充电。当直流充电电路以恒流的方式给电池充电时，直流充电电路的输出电流是恒定的，在本实施例中，处理器112还可以调节直流充电电路输出的恒定电流的大小。例如，处理器112根据电池的温度控制直流充电电路给电池充电的电流大小。
处理器112可以是通用或者专用的处理器。一个或多个处理器112与每个充电电路即充电电路1、充电电路2、充电电路3、充电电路4分别电连接，处理器112用于：获取所述充电电路的电参数信息；根据所述充电电路的电参数信息，控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电，或/及给与所述第一充电接口连接的第一外部设备充电。处理器112具体可以是微控制单元(Micro Controller Unit，简称MCU)。
所述处理器控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电时，具体用于：控制所述充电电路以先恒流后恒压的方式给所述至少一个电池充电。具体的，以充电电路1为例，处理器112 可控制充电电路1以先恒流后恒压的方式给电池B1和电池B2充电中的至少一个电池充电。同理，处理器112还可控制充电电路2以先恒流后恒压的方式给电池B3和电池B4充电中的至少一个电池充电，控制充电电路3以先恒流后恒压的方式给电池B5和电池B6充电中的至少一个电池充电，控制充电电路4以先恒流后恒压的方式给电池B7和电池B8充电中的至少一个电池充电。
当所述充电电路给至少一个电池开始充电时，所述充电电路的输出电流恒定，以对所述至少一个电池进行恒流充电。例如，当充电电路1给电池B1开始充电时，充电电路1的输出电流恒定，也就是说，当充电电路1给电池B1开始充电时，充电电路1对电池B1进行恒流充电，以使电池B1的电量快速增加，当电池B1的电量增加到预设电量时，处理器112可进一步控制充电电路1的输出电压恒定，即控制充电电路1对电池B1进行恒压充电。
在本实施例中，处理器112可实时获取充电电路的电参数信息，例如处理器112可实时获取充电电路1、充电电路2、充电电路3、充电电路4分别的电参数信息，可选的，所述充电电路的电参数信息包括如下至少一种：所述充电电路的输出功率、所述充电电路的输出电流、所述充电电路的输出电压。进一步的，处理器112还可根据每个充电电路的电参数信息，控制该充电电路可选择性地给与该充电电路连接的至少一个电池充电，或/及给与所述第一充电接口连接的第一外部设备充电。例如，处理器112根据充电电路1的电参数信息，控制充电电路1可选择性地给电池B1和电池B2中的至少一个电池充电，或/及给与第一充电接口111连接的第一外部设备充电。
所述处理器根据所述充电电路的电参数信息，控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电，或/及给与所述第一充电接口连接的第一外部设备充电时，具体用于：当所述充电电路从输出恒定电流转变为输出恒定电压时，控制所述充电电路同时给另外一个或多个所述电池或/及所述第一外部设备进行恒流充电。例如，充电电路1先以恒定电流给电池B1充电，当电池B1的电量增加到预设电量时，充电电路1转变为以恒定电压给电池B1充电，当电池B1从恒流充电模式 转变为恒压充电模式时，表示充电电路1给电池B1充电的电流减少，减少的这部分电流可用于给电池B2充电，也可用于给第一充电接口111连接的第一外部设备充电，还可用于同时给电池B2和第一充电接口111连接的第一外部设备充电。可选的，当电池B1从恒流充电模式转变为恒压充电模式时，处理器112可控制充电电路1以恒定电压给电池B1充电的同时给电池B2或/及第一充电接口111连接的第一外部设备进行恒流充电。当电池B2从恒流充电模式转变为恒压充电模式时，表示充电电路1给电池B2充电的电流减少，减少的这部分电流可用于给第一充电接口111连接的第一外部设备充电，也可以输出给充电电路2，充电电路2可结合充电电路1节省的电流和充电电路2原有的电流对电池B3和电池B4充电，充电电路2给电池B3和电池B4充电的方式与充电电路1给电池B1和电池B2充电的方式类似，此处不再赘述，同理，充电电路2给电池B3和电池B4充电的同时还可以给第一充电接口111连接的第一外部设备充电。充电电路3和充电电路4的充电过程以此类推，此处不再赘述。
另外，处理器112还用于：检测与所述充电电路连接的至少一个电池的剩余电量；当所述至少一个电池均充满时，控制所述充电电路给与所述第一充电接口连接的第一外部设备充电。例如，当充电电路1以恒定电压给电池B1和电池B2充电时，电池B1和电池B2可能还未充满，充电电路1还需以恒定电压给电池B1和电池B2充电一段时间才能将电池B1和电池B2充满，此时，处理器112可实时检测电池B1和电池B2的剩余电量，当处理器112根据电池B1和电池B2的剩余电量确定电池B1和电池B2均被充满时，处理器112控制充电电路1给第一充电接口111连接的第一外部设备充电。同理，当充电电路2将电池B3和电池B4充满时，处理器112控制充电电路2给第一充电接口111连接的第一外部设备充电。当充电电路3将电池B5和电池B6充满时，处理器112控制充电电路3给第一充电接口111连接的第一外部设备充电。当充电电路4将电池B7和电池B8充满时，处理器112控制充电电路4给第一充电接口111连接的第一外部设备充电。
可以理解的是，当交流电源经过适配器转换为直流电源，多个充电电路将直流电源以先恒流后恒压的方式给多个电池充电的同时，若第一 充电接口111连接有第一外部设备，则从多个充电电路中分出来一部分直流电给第一外部设备充电，给电池充电的电流会减小，若第一充电接口111没有连接第一外部设备，则以最大功率给电池充电。
本实施例通过多路充电电路对多个电池同时进行充电，节省了电池的充电时间，另外，充电系统中的处理器根据多个充电电路中每个充电电路的电参数信息，控制多个充电电路可选择性地给多个电池充电，或/及给外部设备充电，使得多个充电电路在给多个电池充电的同时还可以给外部设备例如无人机的遥控设备、拍摄设备等充电，从而提高了无人飞行器的工作效率。

另外，如图2所示，充电系统还包括：散热装置114和放电电阻115，每个电池的正极与一个第二单向导通器件的输入端电连接；每个第二单向导通器件的输出端与放电电阻115电连接；及每个第二单向导通器件的输出端与散热装置114电连接。例如，电池B1的正极与理想二极管D1的输入端电连接；电池B2的正极与理想二极管D2的输入端电连接；电池B3的正极与理想二极管D3的输入端电连接；电池B4的正极与理想二极管D4的输入端电连接；电池B5的正极与理想二极管D5的输入端电连接；电池B6的正极与理想二极管D6的输入端电连接；电池B7的正极 与理想二极管D7的输入端电连接；电池B8的正极与理想二极管D8的输入端电连接。理想二极管D1-D8的输出端与放电电阻115电连接，可选的，所述放电电阻包括：正温度系数热敏电阻(Positive Temperature Coefficient，简称PTC)。在其他实施例中，放电电阻115也可以是常规电阻。另外，理想二极管D1-D8的输出端还与散热装置114电连接。可选的，散热装置114包括：风扇。
具体的，每个第二单向导通器件的输出端通过第二开关与所述放电电阻电连接。如图2所示，理想二极管D1-D8的输出端通过第二开关S9与放电电阻115电连接。处理器112还用于：通过控制所述第二开关闭合，以使每个电池通过所述放电电阻放电。即处理器112可通过控制第二开关S9闭合，以使电池B1-B8通过放电电阻115例如正温度系数热敏电阻放电，同时还可以通过风扇给该充电系统降温。
在一些实施例中，处理器112还用于：获取所述电池的电参数信息；根据所述电池的电参数信息，确定所述电池是否异常；若所述电池异常，则控制所述第二开关闭合，以使每个电池通过所述放电电阻放电。如图2所示，由于电池B1-B8分别与处理器112电连接，处理器112可实时获取到每个电池的电参数信息，例如电池的电量、寿命、温度等，并且处理器112可根据电池的电参数信息确定电池是否异常，例如电池的温度大于预设温度阈值，则处理器112确定该电池异常，以使处理器112可控制第二开关S9闭合，以使电池B1-B8通过放电电阻115例如正温度系数热敏电阻放电，同时还可以通过风扇给该充电系统降温。
另外，当每个电池通过所述放电电阻放电时，所述电池给与所述第一充电接口连接的第一外部设备充电。如图2所示，当电池B1-B8通过放电电阻115放电时，处理器112还可以进一步控制开关S1-S8中的一个或多个闭合，可选的，处理器112控制开关S1-S8均闭合，此时，电池B1和电池B2将通过二极管D9给第一充电接口111连接的第一外部设备充电，电池B3和电池B4将通过二极管D10给第一充电接口111连接的第一外部设备充电，电池B5和电池B6将通过二极管D11给第一充电接口111连接的第一外部设备充电，电池B7和电池B8将通过二极管D12给第一充电接口111连接的第一外部设备充电。
此外，当每个电池通过所述放电电阻放电时，所述处理器还用于：检测所述电池的剩余电量；当所述电池的剩余电量小于或等于第一剩余电量阈值时，控制所述第二开关断开，以使每个电池停止放电。如图2所示，当电池B1-B8通过放电电阻115开始放电时，电压较高的电池优先放电，当电池B1-B8的电压相同时，电池B1-B8将同时放电。电池B1-B8在放电的过程中，处理器112还可以检测每个电池的剩余电量，当每个电池的剩余电量小于或等于预设的剩余电量阈值时，控制第二开关S9断开，以使电池B1-B8停止放电。
可选的，每个电池放置在一个电池槽内，如图3所示，电池B1放置在电池槽31内，电池槽31与开关S1和理想二极管D1电连接；电池B2放置在电池槽32内，电池槽32与开关S2和理想二极管D2电连接；电池B3放置在电池槽33内，电池槽33与开关S3和理想二极管D3电连接；电池B4放置在电池槽34内，电池槽34与开关S4和理想二极管D4电连接；电池B5放置在电池槽35内，电池槽35与开关S5和理想二极管D5电连接；电池B6放置在电池槽36内，电池槽36与开关S6和理想二极管D6电连接；电池B7放置在电池槽37内，电池槽37与开关S7和理想二极管D7电连接；电池B8放置在电池槽38内，电池槽38与开关S8和理想二极管D8电连接。在本实施例中，电池和电池槽的对应关系可以不唯一，也就是说电池B1还可以放置在除电池槽31之外的电池槽内，同理电池B2-B8也可以放置在其他的电池槽内。当第二开关S9闭合时，电池B1-B8中的任一电池在任一电池槽内均可以放电。
如图2或图3所示，充电系统还包括第一输出接口116，第一输出接口116用于给充电系统供电；每个第二单向导通器件例如理想二极管D1-D8的输出端通过第一输出接口116与散热装置114的一端电连接，散热装置114的另一端通过第三开关S10、S11和处理器112电连接。
散热装置114具体可以是风扇。当每个电池例如电池B1-B8通过放电电阻115放电时，处理器112还用于：控制第三开关S10、S11闭合，以使风扇给充电系统降温。在其他实施例中，处理器112还用于：根据电池的电参数信息，控制风扇的风速。例如处理器112根据电池的温度控制风扇的风速。
如图2或图3所示，适配器113与每个充电电路例如充电电路1-4电连接，适配器113用于将交流电源转换为直流电源，以使充电电路1-4将直流电源以先恒流后恒压的方式给至少一个电池充电。充电电路1-4给电池B1-B8充电的同时，适配器113通过第一输出接口116给所述充电系统供电。
在其他实施例中，假设充电系统没有适配器113，在没有适配器113的情况下，电池B1-B8也可以通过第一输出接口116给所述充电系统供电，在电池B1-B8给所述充电系统供电的同时处理器112控制电池B1-B8通过放电电阻115放电。具体的，当每个电池通过所述放电电阻放电时，每个电池通过所述第一输出接口给所述充电系统供电。例如，在没有适配器113的情况下，电池B1-B8通过放电电阻115放电时，电池B1-B8通过第一输出接口116给充电系统供电，例如，电池B1-B8通过第一输出接口116给直流转直流电路1供电，直流转直流电路1给散热装置114供电，此外，电池B1-B8还通过第一输出接口116给直流转直流电路2供电，直流转直流电路2给处理器112供电。
可选的，每个电池通过所述第一输出接口给所述充电系统供电之前，每个电池通过第二输出接口给所述充电系统供电，以启动所述充电系统。在本实施例中，每个电池可以有两个输出接口，如图4所示，电池40可以是电池B1-B8中的任一个电池，电池40有两个输出接口，一个输出接口是17.9V接口，另一个输出接口是26.3V接口，当电池控制系统没有启动时，电池40通过17.9V接口给电池控制系统中的微控制单元供电，以启动微控制单元，微控制单元启动后控制电池40与26.3V接口电连接，例如，微控制单元控制电池40与26.3V接口之间的开关41闭合，以使电池40通过26.3V接口向外供电。可选的，图2或图3所示的第一输出接口116具体为每个电池的26.3V接口，图2或图3所示的第二输出接口117具体为每个电池的17.9V接口。可以理解的是，电池B1-B8通过第一输出接口116给充电系统供电之前，电池B1-B8通过第二输出接口117给充电系统供电，以启动充电系统。充电系统启动之后，再由电池B1-B8通过第一输出接口116给充电系统供电。
如图2或图3所示，适配器113可以给充电系统供电，电池B1-B8通 过第一输出接口116或第二输出接口117可以给充电系统供电，当适配器113不给充电系统供电，且电池B1-B8不给充电系统供电时，还可以通过USB接口200给充电系统供电，以保证处理器112不断电。
本实施例通过放电电阻给电池放电的同时控制风扇给充电系统降温，有效增大了充电系统的散热功率，缩短了电池放电时间，从而解决了电池在存储或运输之前的放电问题。另外，放电电阻采用正温度系数热敏电阻，当正温度系数热敏电阻达到最大温度后其温度将保持稳定，避免了热量积累的风险。通过多个理想二极管将多个电池并联在一起，多个电池并联后通过一个正温度系数热敏电阻放电，节省了正温度系数热敏电阻的数量和成本。
本发明实施例提供一种充电系统。图5为本发明实施例提供的充电系统的结构图。在上述实施例的基础上，例如在图2所示实施例的基础上，本实施例中的充电系统还包括：第二充电接口118，第二充电接口118与第一输出接口116电连接，用于给第二外部设备充电。所述第二外部设备包括：用户终端设备。如图5所示，第二充电接口118与第一输出接口116通过直流转直流电路1和充电电路5电连接，其中，充电电路5具体可以是USB充电器，第二充电接口118具体可以是两路USB接口。当第二充电接口118连接有第二外部设备时，充电系统给第二外部设备充电的方式有以下几种可能的情况：
一种可能的情况是：当每个电池通过所述放电电阻放电时，每个电池通过所述第一输出接口给与所述第二充电接口连接的第二外部设备充电。
例如，电池B1-B8通过放电电阻115放电，同时电池B1-B8通过第一输出接口116对外供电，也就是说，电池B1-B8通过第一输出接口116给充电系统供电，具体的，电池B1-B8通过第一输出接口116给直流转直流电路1供电，直流转直流电路1给充电电路5供电，充电电路5进一步给连接第二充电接口118的第二外部设备充电。
另一种可能的情况是：当所述适配器通过所述第一输出接口给所述充电系统供电时，所述适配器通过所述第一输出接口给与所述第二充电 接口连接的第二外部设备充电。
适配器113通过充电电路1-4给电池B1-B8充电的同时，适配器113还可以通过理想二极管D1-D8对外供电，具体的，适配器113通过理想二极管D1-D8与第一输出接口116连接，适配器113给第一输出接口116供电，第一输出接口116给直流转直流电路1供电，直流转直流电路1给充电电路5供电，充电电路5进一步给连接第二充电接口118的第二外部设备充电。
在本实施例中，当适配器113给充电系统供电，或者电池B1-B8给充电系统供电时，第二充电接口118均能输出5V电压、2A电流，5V电压、2A电流可以给第二充电接口118连接的第二外部设备充电。
在其他实施例中，用户终端设备也可以连接到第一充电接口111，遥控设备或拍摄设备也可以连接到第二充电接口118，或者，遥控设备连接到第一充电接口111，拍摄设备连接到第二充电接口118。也就是说，本实施例不限定第一充电接口111可连接的外部设备，也不限定第二充电接口118可连接的外部设备。
如图5所示，充电系统还包括：显示设备119，所述显示设备包括：LCD屏幕。显示设备119与处理器112电连接，显示设备119用于显示处理器112获取到的电池B1-B8的电参数信息。另外，当处理器112根据所述电池的电参数信息确定所述电池异常时，处理器112还用于：控制显示设备119显示报警信息。电池的电参数信息具体包括电池的温度、寿命、剩余电量、当前电流、当前电压等。显示设备119可以分别显示电池B1-B8的电参数信息。
本实施例通过显示设备显示电池的电参数信息，实现了电池的电参数信息的可视化，使得电池的电参数信息一目了然。当交流电源经过适配器转换为直流电源，多个充电电路将直流电源以先恒流后恒压的方式给多个电池充电的同时，若第一充电接口连接有第一外部设备，则从多个充电电路中分出来一部分直流电给第一外部设备充电，不需要另外增加交流转直流适配器，节省了交流转直流的成本。另外，当电池放电的同时还可以通过电池给第一充电接口连接的第一外部设备充电。此外，不论是适配器给充电系统供电，还是电池给充电系统供电，第二充电接 口均能输出5V电压、2A电流，以给第二充电接口连接的第二外部设备充电，实现了充电系统对多个外部设备同时充电的功能。
本发明实施例提供一种充电系统。图6为本发明实施例提供的充电系统的结构图。在上述实施例的基础上，所述处理器控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电的方式有如下几种：
第一种方式是：控制所述充电电路依次将所述至少一个电池中的每个电池充满。
如图6所示，充电电路1通过开关S1和开关S2分别与电池1和电池2电连接，充电电路2通过开关S3和开关S4分别与电池3和电池4电连接，充电电路3通过开关S5和开关S6分别与电池5和电池6电连接，充电电路4通过开关S7和开关S8分别与电池7和电池8电连接。
以充电电路1为例，处理器112可控制充电电路1先将电池1充满，再将电池2充满，具体的，处理器112先控制开关S1闭合、开关S2断开，以使充电电路1给电池1充电，当电池1充满时，处理器112再控制开关S1断开、开关S2闭合，以使充电电路1给电池2充电，直至电池2充满后控制开关S2断开。其他充电电路的充电方式与充电电路1的充电方式一致，此处不再一一赘述。
第二种方式是：控制所述充电电路依次给所述至少一个电池中的每个电池充电，并检测充电状态的电池的剩余电量；当所述至少一个电池中每个电池的剩余电量依次达到第二剩余电量阈值后，控制所述充电电路依次将所述至少一个电池中的每个电池充满。
以充电电路1为例，处理器112可控制充电电路1先将电池1的剩余电量充至90％，再将电池2的剩余电量充至90％，接着再将电池1的剩余电量充至100％，最后将电池2的剩余电量充至100％。例如，处理器112先控制开关S1闭合、开关S2断开，以使充电电路1给电池1充电，当电池1的剩余电量充至90％时，处理器112控制开关S1断开、开关S2闭合，以使充电电路1给电池2充电，当电池2的剩余电量充至90％时，处理器112控制开关S1闭合、开关S2断开，以使充电电路1再次给电池1 充电，当电池1的剩余电量充至100％时，处理器112控制开关S1断开、开关S2闭合，以使充电电路1再次给电池2充电，当电池2的剩余电量充至100％时，控制开关S2断开。其他充电电路的充电方式与充电电路1的充电方式一致，此处不再一一赘述。
具体的，第二种方式的充电速度比第一种方式的充电速度快。
本实施例通过控制充电电路依次将多个电池中的每个电池充满，或者控制充电电路依次将多个电池中的每个电池充到预设的电量后再控制该充电电路依次将每个电池充满，增加了对电池充电的灵活性。
本发明实施例提供一种充电方法。图7为本发明实施例提供的充电方法的流程图。如图7所示，本实施例中的方法，可以包括：
步骤S701、获取至少一个充电电路中每个充电电路的电参数信息，每个充电电路用于给至少一个电池充电。
本实施例的执行主体具体可以是上述实施例中的处理器112，处理器112可以是通用或者专用的处理器。处理器112可实时获取充电电路的电参数信息，例如处理器112可实时获取充电电路1、充电电路2、充电电路3、充电电路4分别的电参数信息，可选的，所述充电电路的电参数信息包括如下至少一种：所述充电电路的输出功率、所述充电电路的输出电流、所述充电电路的输出电压。
步骤S702、根据所述充电电路的电参数信息，控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电，或/及给第一外部设备充电。
例如，处理器112根据充电电路1的电参数信息，控制充电电路1可选择性地给电池B1和电池B2中的至少一个电池充电，或/及给与第一充电接口111连接的第一外部设备充电。
具体的，所述控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电，包括：控制所述充电电路以先恒流后恒压的方式给所述至少一个电池充电。具体的，以充电电路1为例，处理器112可控制充电电路1以先恒流后恒压的方式给电池B1和电池B2充电中的至少一个电池充电。当所述充电电路给至少一个电池开始充电时，所述充电电 路的输出电流恒定，以对所述至少一个电池进行恒流充电。例如，当充电电路1给电池B1开始充电时，充电电路1对电池B1进行恒流充电，以使电池B1的电量快速增加，当电池B1的电量增加到预设电量时，处理器112可进一步控制充电电路1的输出电压恒定，即控制充电电路1对电池B1进行恒压充电。
所述根据所述充电电路的电参数信息，控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电，或/及给第一外部设备充电，包括：当所述充电电路从输出恒定电流转变为输出恒定电压时，控制所述充电电路同时给另外一个或多个所述电池或/及所述第一外部设备进行恒流充电。例如，充电电路1先以恒定电流给电池B1充电，当电池B1的电量增加到预设电量时，充电电路1转变为以恒定电压给电池B1充电，当电池B1从恒流充电模式转变为恒压充电模式时，表示充电电路1给电池B1充电的电流减少，减少的这部分电流可用于给电池B2充电，也可用于给第一充电接口111连接的第一外部设备充电，还可用于同时给电池B2和第一充电接口111连接的第一外部设备充电。可选的，当电池B1从恒流充电模式转变为恒压充电模式时，处理器112可控制充电电路1以恒定电压给电池B1充电的同时给电池B2或/及第一充电接口111连接的第一外部设备进行恒流充电。当电池B2从恒流充电模式转变为恒压充电模式时，表示充电电路1给电池B2充电的电流减少，减少的这部分电流可用于给第一充电接口111连接的第一外部设备充电，也可以输出给充电电路2，充电电路2可结合充电电路1节省的电流和充电电路2原有的电流对电池B3和电池B4充电，充电电路2给电池B3和电池B4充电的方式与充电电路1给电池B1和电池B2充电的方式类似，此处不再赘述，同理，充电电路2给电池B3和电池B4充电的同时还可以给第一充电接口111连接的第一外部设备充电。充电电路3和充电电路4的充电过程以此类推，此处不再赘述。
另外，处理器112还用于：检测与所述充电电路连接的至少一个电池的剩余电量；当所述至少一个电池均充满时，控制所述充电电路给与所述第一充电接口连接的第一外部设备充电。例如，当充电电路1以恒定电压给电池B1和电池B2充电时，电池B1和电池B2可能还未充满，充电 电路1还需以恒定电压给电池B1和电池B2充电一段时间才能将电池B1和电池B2充满，此时，处理器112可实时检测电池B1和电池B2的剩余电量，当处理器112根据电池B1和电池B2的剩余电量确定电池B1和电池B2均被充满时，处理器112控制充电电路1给第一充电接口111连接的第一外部设备充电。
每个充电电路通过一个第一单向导通器件与所述第一外部设备电连接。如图1所示，充电电路1通过二极管D9与第一充电接口111电连接；充电电路2通过二极管D10与第一充电接口111电连接；充电电路3通过二极管D11与第一充电接口111电连接；充电电路4通过二极管D12与第一充电接口111电连接。
每个电池通过一个第一开关与给所述电池充电的充电电路电连接。如图1所示，电池B1通过开关S1与充电电路1电连接，电池B2通过开关S2与充电电路1电连接；电池B3通过开关S3与充电电路2电连接，电池B4通过开关S4与充电电路2电连接；电池B5通过开关S5与充电电路3电连接，电池B6通过开关S6与充电电路3电连接；电池B7通过开关S7与充电电路4电连接，电池B8通过开关S8与充电电路4电连接。
所述控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电，包括：控制与所述充电电路连接的至少一个第一开关闭合，以使所述充电电路给与所述充电电路连接的至少一个电池充电。例如，处理器112通过控制开关S1闭合，以使充电电路1给电池B1充电。
本实施例通过多路充电电路对多个电池同时进行充电，节省了电池的充电时间，另外，充电系统中的处理器根据多个充电电路中每个充电电路的电参数信息，控制多个充电电路可选择性地给多个电池充电，或/及给外部设备充电，使得多个充电电路在给多个电池充电的同时还可以给外部设备例如无人机的遥控设备、拍摄设备等充电，从而提高了无人飞行器的工作效率。
本发明实施例提供一种充电方法。图8为本发明实施例提供的充电方法的流程图。在图7所示实施例的基础上，每个电池与一个第二单向导通器件电连接，每个电池通过各第二单向导通器件并联。如图2所示，电池 B1-B8分别与一个理想二极管电连接，理想二极管D1-D8将电池B1-B8并联在一起。
每个电池的正极与一个第二单向导通器件的输入端电连接；每个第二单向导通器件的输出端与放电电阻电连接；及每个第二单向导通器件的输出端与散热装置电连接。如图2所示，电池B1-B8的正极分别与一个理想二极管电连接。理想二极管D1-D8的输出端与放电电阻115电连接。另外，理想二极管D1-D8的输出端还与散热装置114电连接。放电电阻115具体可以采用正温度系数热敏电阻。散热装置114具体可以是风扇。
每个第二单向导通器件的输出端通过第二开关与所述放电电阻电连接。如图2所示，理想二极管D1-D8的输出端通过第二开关S9与放电电阻115电连接。在本实施例中，处理器112可通过控制第二开关S9闭合，以使每个电池通过所述放电电阻放电。
当每个电池通过所述放电电阻放电时，所述方法还包括如下步骤：
步骤S801、检测所述电池的剩余电量。
步骤S802、当所述电池的剩余电量小于或等于第一剩余电量阈值时，控制所述第二开关断开，以使每个电池停止放电。
如图2所示，当电池B1-B8通过放电电阻115开始放电时，电压较高的电池优先放电，当电池B1-B8的电压相同时，电池B1-B8将同时放电。电池B1-B8在放电的过程中，处理器112还可以检测每个电池的剩余电量，当每个电池的剩余电量小于或等于预设的剩余电量阈值时，控制第二开关S9断开，以使电池B1-B8停止放电。
另外，当每个电池通过所述放电电阻放电时，所述电池给与所述第一充电接口连接的第一外部设备充电。如图2所示，当电池B1-B8通过放电电阻115放电时，处理器112还可以进一步控制开关S1-S8中的一个或多个闭合，可选的，处理器112控制开关S1-S8均闭合，此时，电池B1和电池B2将通过二极管D9给第一充电接口111连接的第一外部设备充电，电池B3和电池B4将通过二极管D10给第一充电接口111连接的第一外部设备充电，电池B5和电池B6将通过二极管D11给第一充电接口111连接的第一外部设备充电，电池B7和电池B8将通过二极管D12给第一充电接口111连接的第一外部设备充电。
此外，当每个电池通过所述放电电阻放电时，每个电池通过所述第二单向导通器件给所述散热装置供电。例如电池B1-B8通过放电电阻115放电的同时还可以通过风扇给该充电系统降温。
本实施例通过放电电阻给电池放电的同时控制风扇给充电系统降温，有效增大了充电系统的散热功率，缩短了电池放电时间，从而解决了电池在存储或运输之前的放电问题。另外，放电电阻采用正温度系数热敏电阻，当正温度系数热敏电阻达到最大温度后其温度将保持稳定，避免了热量积累的风险。通过多个理想二极管将多个电池并联在一起，多个电池并联后通过一个正温度系数热敏电阻放电，节省了正温度系数热敏电阻的数量和成本。

步骤S901、检测所述电池的电参数信息。
处理器112可实时获取到每个电池的电参数信息，例如电池的电量、寿命、温度等。
步骤S902、根据所述电池的电参数信息，控制所述散热装置的散热速度。
例如处理器112根据电池的温度控制风扇的风速。
在步骤S901检测所述电池的电参数信息之后，还可以包括：通过显示设备显示所述电池的电参数信息。
如图5所示，显示设备119与处理器112电连接，显示设备119用于显示处理器112获取到的电池B1-B8的电参数信息。
或者，在步骤S901检测所述电池的电参数信息之后，还可以包括：根据所述电池的电参数信息确定所述电池是否异常；若所述电池异常，则通过显示设备显示报警信息。
当处理器112根据所述电池的电参数信息确定所述电池异常时，处理器112还用于：控制显示设备119显示报警信息。
每个第二单向导通器件的输出端还与第二外部设备连接。如图5所示，理想二极管D1-D8的输出端通过第一输出接口116与第二充电接口 118电连接，第二充电接口118用于给第二外部设备充电。第二充电接口118具体可以是两路USB接口。
当所述电池通过所述放电电阻放电时，所述电池通过所述第二单向导通器件给所述第二外部设备充电。例如，电池B1-B8通过放电电阻115放电，同时电池B1-B8通过第一输出接口116对外供电，也就是说，电池B1-B8通过第一输出接口116给充电系统供电，具体的，电池B1-B8通过第一输出接口116给直流转直流电路1供电，直流转直流电路1给充电电路5供电，充电电路5进一步给连接第二充电接口118的第二外部设备充电。
所述处理器控制所述充电电路可选择性地给与所述充电电路连接的至少一个电池充电的方式有如下几种：
第一种方式是：控制所述充电电路依次将所述至少一个电池中的每个电池充满。
第二种方式是：控制所述充电电路依次给所述至少一个电池中的每个电池充电，并检测充电状态的电池的剩余电量；当所述至少一个电池中每个电池的剩余电量依次达到第二剩余电量阈值后，控制所述充电电路依次将所述至少一个电池中的每个电池充满。
上述两种方式的具体原理和实现方式均与图6所示实施例类似，此处不再赘述。
