具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员 在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
以下分别进行详细说明。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
在常用的车载OBC解决方案中，OBC一般独立于DC/DC变换器设置，该方案虽然节省了部分结构件和端口配线，但仍需要大量的电气元件，成本高、体积大，集成化程度较低。市电输入通过EMC滤波电路、单相整流电路、PFC功率校正电路、OBC输入侧开关电路进入OBC主变压器，再通过OBC输出侧整流电路、OBC输出侧滤波电路将能量传递给动力电池组，动力电池组将能量通过DC/DC输出侧EMC滤波电路、DC/DC输入侧开关的电路传递给DC/DC主变压器，并通过DC/DC主变压器将能量通过DC/DC输出侧整流电路、DC/DC输出侧滤波电路传输给蓄电池。现有的电气集成方案只能实现电池充电的单一功能，并不能满足现实的多样性需求。
针对上述问题，本申请实施例提出一种集成车载充电机电路及集成车载充电机，该集成车载充电机电路包括原边处理电路、变压器、第一副边处理电路、第二副边处理电路、开关K 1、开关K 2、动力电池、低压电池、控制单元和整流电路，其中：

控制单元用于控制固定端与第一选择端或第二选择端连接，当固定端与第一选择端连接时，整流电路、原边处理电路、变压器以及第一副边处理电路形成的第一处理电路用于将市电的第一部分能量传输到动力电池；整流电路、原边处理电路、变压器以及第二副边处理电路形成的第二处理电路用于将市电的第二部分能量传输到低压电池；当固定端与第二选择端连接时，原边处理电路、变压器以及第一副边处理电路形成的第三处理电路用于将动力电池的第一部分能量回馈到动力电池，原边处理电路、变压器以及第二副边处理电路形成的第四处理电路用于将动力电池的第二部分能量传输到低压电池；通过控制变压器的第一副边绕组与第二副边绕组之间的距离，进而控制漏感、控制耦合，从而实现将市电的能量通过不同的处理电路传输到动力电池和低压电池，以及将动力电池的能量通过不同 的处理电路回馈到动力电池和传输到低压电池。解决了传统集成车载充电机功能单一，难以满足集成车载充电机在未来场景中的多样化使用需求的问题。
