具体实施方式
通过下述实施例并结合附图，对本申请实施例中的技术方案进行说明。应当理解，此处所描述的实施例仅用以解释本申请。
图1为本申请实施例提供的智能太阳能光伏组件的一种结构示意图。参见图1-图3所示，该智能太阳能光伏组件可以包括：太阳能光伏组件本体10和位于所述太阳能光伏组件本体10上的智能接线盒11，所述智能接线盒11包括多个相互连通的太阳能控制器110；所述太阳能光伏组件本体10中的多个电池串101通过汇流条102分别与所述多个太阳能控制器110的接线端子1100一一电连接。
在一实施例中，智能接线盒11设置在太阳能光伏组件本体10的背板上，其包含多个相互连通的太阳能控制器(Maximum Power Point Tracking，MPPT)110。每个电池串101分别与太阳能控制器110的接线端子1100一一电连接，主要通过太阳能控制器110检测电池串101的端电压来判断电池串101是否处于正常的工作状态。一旦太阳能控制器110检测到一电池串101的电压不一样，就认为低电压的电池串101出现了热斑效应，其输出电流就会变小，与其串联的其他电池串101都会受制于此低电流。智能接线盒11通过太阳能控制器110对多个电池串101的电压检测，来调整改变太阳能光伏组件本体10的输出电压，同时改变输出电流，直到太阳能光伏组件本体10的输出功率达到最大点。
在本实施例中，可以使用智能接线盒11代替传统的二极管接线盒，太阳能光伏组件本体10中的多个电池串101封装在面板和背板之间，多个电池串101通过汇流条102将电能引出背板，并与智能接线盒11中的太阳能控制器110的接线端子1100一一电连接。
作为一种可选地实施方式，可以通过在太阳能光伏组件本体10内部对多个电池串101的汇流条102进行布局走线，以将多个电池串101的电能一一引出至智能接线盒11内的接线端子1100处。接下来，介绍在太阳能光伏组件本体10内部通过改变汇流条102布局的方式来实现电能引出的方案。
可选地，太阳能光伏组件本体10中的至少两个电池串101的汇流条102在太阳能光伏组件本体10内部错位布局。参见图2(图2中示出了太阳能光伏组件本体10中包括6个电池串101)，可选地，一种汇流条102错位布局的方式可以为：太阳能光伏组件本体10中的至少两个电池串101的汇流条102以弯折绕行方式错位布局，汇流条102中与每个电池串101的重叠部分设置有绝缘片。其中，汇流条102的弯折角度可以为任意角度。作为一种可选地实施方式，汇流条102的弯折角度可以为90度。可选地，绝缘片可以为绝缘胶带、绝缘漆或绝缘塑料中的任意一种。也就是说，每个电池串101的汇流条102可以先横向 走线、再弯折90度竖向走线，再弯折90度横向走线，再弯折90度竖向走线，直至连接到智能接线盒11中的接线端子1100处。需要说明的是，图2所示的绕行布局方式仅是一种示例，还可以是其它方式的弯折绕行布局方式，只要通过弯折绕行实现多个电池串101的汇流条102错位布局即可。
多个电池串101的汇流条以弯折绕行错位布局的方式将多个电池串101的电能引出至智能接线盒11中，该方式能够减少在电能引出时多层汇流条的绝缘片叠加所带来的高度产生的工艺脱层、气泡甚至可靠性问题。同时，汇流条的折弯绕行可在线下完成定位焊接，并不影响太阳能光伏组件本体10生产流水线的节拍速度。
参见图3，可选地，另一种汇流条102错位布局的方式可以为：通过将部分电池串101的互联条103(即焊带)预留，使得部分电池串101或全部电池串101的汇流条102错位布局。可选地，太阳能光伏组件本体10中的至少两个电池串101的互联条103在与智能接线盒11同方向的一端的预留长度不同，每个电池串101预留出的互联条103的上层对应焊接有与太阳能控制器110的接线端子1100电连接的汇流条102。每个汇流条102可以呈倒“L”型布局。可选地，多个汇流条102的重叠部分设置有绝缘片。可选地，绝缘片可以为绝缘胶带、绝缘漆或绝缘塑料中的任意一种。
假设图3中示出的电池串从左至右分别为电池串1、电池串2、电池串3、电池串4、电池串5和电池串6，从图3可以看出，电池串1和电池串2的汇流条102在横向上错位布局，电池串5和电池串6的汇流条102在横向上错位布局，电池串1和电池串3的汇流条102在横向上存在部分重叠，电池串4和电池串6的汇流条102在横向上存在部分重叠，上述重叠部分设置有绝缘片。需要说明的是，图3所示的汇流条错位布局方式仅是一种示例，还可以是其它的汇流条错位布局方式，只要通过将至少两个电池串的互联条预留长度不同来实现汇流条的错位布局即可。
该方式可以减少汇流条的使用量，也可以降低多层汇流条叠加以及汇流条间多层绝缘形成的高度带来的工艺和可靠性难题。
接下来，介绍另外一种通过汇流条102将多个电池串101的电能引出背板并接入到智能接线盒11中的方案，该方案无需在太阳能光伏组件本体10内部进行复杂的汇流条走线。
可选地，所述智能接线盒11的两侧分别设置有多个外接接线端子；太阳能光伏组件本体10中靠近外侧的电池串101的汇流条102无需在太阳能光伏组件本体10内部走线直接穿过背板，并通过所述多个外接接线端子与智能接线盒11内的接线端子1100一一电连接，位于中间位置的电池串101的汇流条102无需 在太阳能光伏组件本体10内部走线直接穿过背板与智能接线盒11内的空闲接线端子1100一一电连接。
本实施例中，可以在太阳能光伏组件本体10的背板上开孔，孔可以开设于相邻电池串101的中间位置，这样，太阳能光伏组件本体10两侧电池串101的汇流条102便可以直接从孔中引出，并接入至所述外接接线端子上，外接接线端子再通过线缆与智能接线盒11内的接线端子1100一一电连接。位于太阳能光伏组件本体10中间位置的电池串101的汇流条102也可以从距离最近的孔中引出，接入至智能接线盒11内的空闲接线端子1100上，从而实现了所有电池串101的电能引出。
该方式通过在太阳能光伏组件本体10的背板上设置外接接线端子，将多个电池串101的电能通过外部连接方式引出至智能接线盒11内，实现了电能引出的效果，无需在太阳光伏组件本体内部进行复杂的汇流条走线。
本申请实施例提供的智能太阳能光伏组件，包括：太阳能光伏组件本体和位于太阳能光伏组件本体上的智能接线盒，智能接线盒包括多个相互连通的太阳能控制器，太阳能光伏组件本体中的多个电池串通过汇流条分别与所述多个太阳能控制器的接线端子一一电连接，从而通过多个太阳能控制器实时对每个电池串的电压进行检测，动态调整改变太阳能光伏组件本体的输出电压和输出电流，实现太阳能光伏组件本体的最大功率输出。并且，该智能接线盒可直接通过汇流条与太阳能光伏组件本体内部电路连接，无需通过二极管接线盒与太阳能光伏组件本体内部电路连接，减少了二极管接线盒与智能接线盒间的线缆与接头连接，降低了接头连接与线损等引起的功率损失。并且，提供了多种电池串的电能引出方案，如采用多个电池串的汇流条以弯折绕行错位布局的方式，以及将至少两个电池串的互联条预留长度不同来实现汇流条的错位布局的方式，以及通过在太阳能光伏组件本体的背板上进行走线的方式，将多个电池串的电能引出至智能接线盒中。
