在第一时间段内，控制器控制第二晶体管VT2、第四晶体管VT4以及第六晶体管VT6导通，并控制第一晶体管VT1、第三晶体管VT3以及第五晶体管VT5关闭，使得光伏太阳能模组130的能量储存到 所述第一电感L1、第二电感L2和第三电感L3。
在第二时间段内，控制器控制第一晶体管VT1、第三晶体管VT3以及第五晶体管VT5导通，并控制第二晶体管VT2、第四晶体管VT4以及第六晶体管VT6关闭，使得第一电感L1、第二电感L2和第三电感L3中储存的能量释放到所述动力电池140。
通过此方式进行动力电池140的充电时直流充电加光伏充电，第一时间段内直流充电口122进行直流充电，第二时间段内电感模组将存储的光伏电能输送给动力电池140。这样的充电过程可以简称为直流直充+光伏充电。
如图2(c)、图2(d)，第一开关K1连接第一电感L1和第三电感L3、第二开关K2连接第二电感L2和交流充电口121、第三开关K3连接交流充电口121和第三桥臂113、第四开关K4断开、第五开关K5连接直流充电口122和交流充电口121、第六开关K6闭合、第七开关K7断开。

上述过程中直流充电口122不会对动力电池140直接进行充电，直流充电口122的能量先存储到第二电感L2中，光伏电能先存储到第一电感L1和第三电感L3中，在第二时间段内，第二电感L2存储的直流升压电流对动力电池140进行充电，第一电感L1和第三电感L3存储的光伏电能也对动力电池140进行充电。这样的充电过程可以简称为直流升压充电+光伏充电。
相应的上述情况还有另一种实现方式：
第一开关K1连接第一电感L1和交流充电口121、第二开关K2连接第二电感L2和第三电感L3、第三开关K3连接交流充电口121和第三桥臂113、第四开关K4断开、第五开关K5连接直流充电口122和交流充电口121、第六开关K6断开且第七开关K7闭合。
在第一时间段内，控制器控制第二晶体管VT2、第六晶体管VT6导通，并控制第一晶体管VT1、第五晶体管VT5关闭，使得直流充电口122中的能量储存到第一电感L1，并且控制第四晶体管VT4导通、第三晶体管VT3关闭，使得光伏太阳能模组130中的能量储存到第二电感L2和第三电感L3。
在第二时间段内，控制器控制第一晶体管VT1、第六晶体管VT6导通，并控制第二晶体管VT2、第五晶体管VT5关闭，使得第一电感L1中储存的能量释放到动力电池140，并且控制第三晶体管VT3导通、第四晶体管VT4关闭，使得第二电感L2和第三电感L3中储存的能量释放到动力电池140。
上述过程中直流充电口122不会对动力电池140直接进行充电，直流充电口122的能量先存储到第一电感L1中，光伏电能先存储到第二电感L2和第三电感L3中，在第二时间段内，第一电感L1存储的直流升压电流对动力电池140进行充电，第二电感L2和第三电感L3存储的光伏电能也对动力电池140进行充电。这样的充电过程是另一种形式的直流升压充电+光伏充电。
如图3(a)-图3(d)所示，第一开关K1连接交流充电口121和第一电感L1、第二开关K2连接第二电感L2和第三电感L3、第三开关K3连接交流充电口121和第三桥臂113、第四开关K4断开、第五开关K5连接直流充电口122和动力电池140、第六开关K6和第七开关K7断开。
在第一时间段内，控制器控制第二晶体管VT2、第六晶体管VT6导通，并控制第一晶体管VT1、第五晶体管VT5关闭，使得交流充电口121中的能量储存到第一电感L1，并且控制第四晶体管VT4导通、第三晶体管VT3关闭，使得光伏太阳能模组130中的能量储存 到第二电感L2和第三电感L3。
在第二时间段内，控制器控制第一晶体管VT1、第六晶体管VT6导通，并控制第二晶体管VT2、第五晶体管VT5关闭，使得第一电感L1中储存的能量释放到动力电池140，并且控制第三晶体管VT3导通、第四晶体管VT4关闭，使得第二电感L2和第三电感L3中储存的能量释放到动力电池140。
在第三时间段内，控制器控制第一晶体管VT1、第五晶体管VT5导通，并控制第二晶体管VT2、第六晶体管VT6关闭，使得交流充电口121中的能量储存到第一电感L1，控制第四晶体管VT4导通、第三晶体管VT3关闭，使得光伏太阳能模组130中的能量储存到第二电感L2和第三电感L3。
在第四时间段内，控制器控制第二晶体管VT2、第五晶体管VT5导通，并控制第一晶体管VT1和第六晶体管VT6关闭，使得第一电感L1中储存的能量释放到动力电池140，并控制第三晶体管VT3导通、第四晶体管VT4关闭，使得第二电感L2和第三电感L3中储存的能量释放到动力电池140。
上述充电过程中，充电口的交流电存储到第一电感L1中，光伏太阳能模组130的能量存储到第二电感L2和第三电感L3中，在对动力电池140充电时，第一电感L1、第二电感L2和第三电感L3再对动力电池140进行充电。因为对第一电感L1充电的充电口为交流充电口121，上述方式可以简称为交流充电+光伏充电。
通过上述的方式，在交流充电口121和直流充电口122分开时，进行交流充电、直流充电以及光伏充电的协同，多相交错控制，有效提升充电效率。一方面可以提升充电效率，另一方面因为光伏电能得到了有效利用，减少了对电网的能量需求，为车主节省了电能成本。

在第三时间段内，控制器控制第一晶体管VT1和第五晶体管VT5导通，并控制第二晶体管VT2和第六晶体管VT6关闭，使得充电口中的能量储存到所述第一电感L1，并控制第四晶体管VT4导通、第三晶体管VT3关闭，使得光伏太阳能模组130中的能量储存到第 二电感L2和所述第三电感L3。
在第四时间段内，控制器控制第二晶体管VT2和第五晶体管VT5导通，并控制第一晶体管VT1和第六晶体管VT6关闭，使得第一电感L1中储存的能量释放到动力电池140，并控制第三晶体管VT3导通、第四晶体管VT4关闭，使得第二电感L2和第三电感L3中储存的能量释放到动力电池140。
上述充电过程同样为交流充电+光伏充电，充电口的交流电存储到第一电感L1中，光伏太阳能模组130的能量存储到第二电感L2和第三电感L3中，在对动力电池140充电时，第一电感L1、第二电感L2和第三电感L3再释放能量到动力电池140中。
需要说明的是，对于交流充电口和直流充电口集成的系统，因为手动选择直流或者交流充电口会较为不便，因此在使用充电口对动力电池140进行充电时，使用针对汽车充电枪的电阻检测电路来识别充电枪的类型和功率等级，再更加用户需求进行协同充电。
通过上述的方式，在交流充电口和直流充电口集成在一起时，进行交流充电、直流充电以及光伏充电的协同，多相交错控制，有效提升充电效率。此外，光伏太阳能模组130为多个光伏模块串联而成的高压太阳能模组，具有足够的电压可以直接为动力电池进行充电，减少逆变次数以提升转换效率。
实施例四
本申请实施例提供了一种充电装置，如图7、图8所示，本装置还包括母线电容c2，母线电容c2的两端分别连接在第一汇流端和第二汇流端上。图2a到图6d中的c2也是与此处的c2类似的器件，起到类似的作用。示例性地，本装置还包括DC-DC模块，DC-DC模块的第一端与第一汇流端连接，DC-DC模块的第二端与第二汇流端连接，DC-DC模块的第三端与动力电池的正极连接，DC-DC模块的第四端与动力电池的负极连接。此外，在动力电池的正负极之间还连接有保护电容c3。DC-DC模块以及保护电容c3可以起到缓冲保护的作用。

示例性地，该缓冲模块可以为：包括串联连接的第一电阻R_PV和第一电容C_PV，串联后的第一端与光伏太阳能模组的正极相连，串联后的第二端与光伏太阳能模组的负极相连。

本申请上述实施例的充电装置，通过光伏太阳能模组、充电口以及电感模组都可以对动力电池进行充电，当充电口为动力电池充电时，光伏太阳能模组产生的电能可以存储到电感模组中，光伏太阳能模组产生的电能不会造成浪费，当充电口没有对动力电池进行充电时，通过电感中存储的能量可以对动力电池充电，同时光伏太阳能模组产生的电能也可以对动力电池进行充电。对光伏太阳能模组的光伏电能进 行充分利用，减少光伏能量的浪费。并且，在本装置中，不管是直流充电口与交流充电口分开设置，还是直流充电口与交流充电口集成在一起，都可以借助第一开关K1模块、第二开关K2模块以及控制器实现对动力电池的协同充电，使用更加方便且适用性更高。

尽管这里已经参考附图描述了示例实施例，应理解上述示例实施例仅仅是示例性的，并且不意图将本申请的范围限制于此。本领域普 通技术人员可以在其中进行各种改变和修改，而不偏离本申请的范围和精神。所有这些改变和修改意在被包括在所附权利要求所要求的本申请的范围之内。
本领域普通技术人员可以意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，能够以电子硬件、或者计算机软件和电子硬件的结合来实现。这些功能究竟以硬件还是软件方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。

此外，本领域的技术人员能够理解，尽管在此所述的一些实施例包括其他实施例中所包括的某些特征而不是其他特征，但是不同实施例的特征的组合意味着处于本申请的范围之内并且形成不同的实施例。例如，在权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
本申请的各个部件实施例可以以硬件实现，或者以在一个或者多个处理器上运行的软件模块实现，或者以它们的组合实现。本领域的技术人员应当理解，可以在实践中使用微处理器或者数字信号处理器(DSP)来实现根据本申请实施例的一些模块的一些或者全部功能。本申请还可以实现为用于执行这里所描述的方法的一部分或者全部的装置程序(例如，计算机程序和计算机程序产品)。这样的实现本申请的程序可以存储在计算机可读介质上，或者可以具有一个或者多个信号的形式。这样的信号可以从因特网网站上下载得到，或者在载体信号上提供，或者以任何其他形式提供。
应该注意的是上述实施例对本申请进行说明而不是对本申请进行限制，并且本领域技术人员在不脱离所附权利要求的范围的情况下可设计出替换实施例。在权利要求中，不应将位于括号之间的任何参考符号构造成对权利要求的限制。单词“包含”不排除存在未列在权利要求中的元件或步骤。位于元件之前的单词“一”或“一个”不排除存在多个这样的元件。本申请可以借助于包括有若干不同元件的硬件以及借助于适当编程的计算机来实现。在列举了若干装置的单元权利要求中，这些装置中的若干个可以是通过同一个硬件项来具体体现。单词第一、第二、以及第三等的使用不表示任何顺序。可将这些单词解释为名称。
以上所述，仅为本申请的具体实施方式或对具体实施方式的说明，本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申 请的保护范围之内。本申请的保护范围应以权利要求的保护范围为准。
