技术领域
本发明涉及一种用于48V轻度混合动力系统的低DC-DC转换器(LDC)集成电池管理装置，并且更具体地，涉及一种其中将独立提供的传统的LDC和48V电池模块集成到一个部件中，在软件中实现了起动发电机的初始驱动功能，并且因此移除预充电继电器和充电电阻器的用于48V轻度混合动力系统的LDC集成电池管理装置。
背景技术
通常，使用电池单元的轻度混合动力系统包括：电池单元管理组件，被配置为控制电池单元用于供应48V的电压；12V电池，被配置为向电子装置供应12V的电压；起动发电机，即48V轻度混合动力起动机和发电机(MHSG)，被配置为使用从电池单元施加的48V的电压来辅助发动机的驱动力，并且具有再生制动功能，其在车辆减速期间对电池充电；48V低DC-DC转换器(LDC)，被配置为向12V电子部件供应电力；以及设备管理控制器，被配置为使用控制器局域网(CAN)来控制每个部件。
在使用电池单元的传统的轻度混合动力系统中，48V LDC和电池单元管理组件是独立分开的。结果，用于48V LDC的控制单元和电池管理系统不可避免地分开。
因此，48V LDC和电池管理系统以独立的组装方式执行其功能。
此外，设备管理控制器通过DC链路电容器(CAP)的电压来控制发动机起动时电池管理系统的电池单元的充电。
同时，传统的电池单元管理组件向48V LDC和48V MHSG供应48V的电压。
然而，在使用电池单元的传统的轻度混合动力系统中，由于电池单元管理组件和48V LDC是独立提供的，因此用于电池单元管理组件和48V LDC的壳体和板的制造成本增加了一倍，并且每一个还需要单独的软件。
此外，由于电池单元管理组件和48V LDC是独立提供的，因此在车辆中安装电池单元管理组件和48V LDC需要工时，并且因此，其安装空间应固定在车辆中。
发明内容
本发明旨在提供一种用于48V轻度混合动力系统的低DC-DC转换器(LDC)集成电池管理装置，其中，对由电子控制单元(ECU)分别控制的电池管理系统和48V轻度混合动力系统的LDC进行整体管理。

当12V的电压被升压到48V的电压并且48V的电压在所述MHSG的DC链路CAP中充电时，所述LDC集成电池模块可以将值与48V的升压电压进行比较，其中，所述值是通过将所述电池单元的电压乘以所述DC链路CAP的充电电压的基准比而获得的，并且作为比较的结果，所述LDC集成电池模块将48V的电压升压到一电平，在该电平下，将所述电池单元的电压乘以所述DC链路CAP的充电电压的所述基准比而获得的所述值大于或等于48V的升压电压的输出电压。
当从所述设备管理控制器输入LDC空闲模式请求时，所述LDC集成电池模块可以停止将12V的电压(LDC升压模式)转换为48V的电压的操作。

具体实施方式
从下面参考附图描述的示例性实施方式，将更清楚地理解本发明的优点和特征以及用于实现本发明的方法。然而，本发明不限于以下示例性实施方式，而是可以以各种不同形式来实现。提供示例性实施方式仅仅是为了完成本发明的公开，以及为了向本发明所属领域的普通技术人员充分提供本发明的范围，并且本发明将由所附权利要求限定。本说明书中使用的术语用于描述示例性实施方式，而不旨在限制本发明。如本文所使用的，除非在上下文中另有定义，否则单数表达式包括复数表达式。将进一步理解，术语“包含(comprises)”、“包含(comprising)”、“包括(includes)”和/或“包括(including)”(如果在本文使用)指定部件、步骤、操作和/或元件的存在，但是不排除一个或多个其他部件、步骤、操作和/或元件的存在或添加。
在下文中，将参考附图详细描述本发明的示例性实施方式。图1是用于描述根据本发明的示例性实施方式的用于48V轻度混合动力系统的低DC-DC转换器(在下文中，称为“LDC”)集成电池管理装置的功能框图。
如图1所示，根据本发明的示例性实施方式的用于48V轻度混合动力系统的LDC集成电池管理装置包括：起动发电机100、12V电池200、LDC集成电池模块300以及设备管理控制器400。
起动发电机100用于在车辆减速期间通过再生制动对电池单元充电，并且在车辆行驶期间辅助发动机的驱动力。起动发电机100是轻度混合动力起动机和发电机(mildhybrid starter and generator，MHSG)。
当车辆的点火装置被启动时，12V电池200用于向起动发电机100和车辆的每个电子部件施加12V的电压。
LDC集成电池模块300使用从12V电池200施加的12V的电压来执行自诊断，并且然后用于将12V的电压转换为48V的电压，并且根据诊断的结果向电池单元和起动发电机100供应48V的电压。
此外，当车辆的点火装置被启动时，设备管理控制器400用于通过控制器局域网(CAN)通信协议控制12V电池200，使得将12V电池200的12V的电压施加到LDC集成电池模块300。此外，设备管理控制器400用于通过CAN通信协议控制LDC集成电池模块300，使得将通过LDC集成电池模块300转换的48V的电压施加到电池单元和起动发电机100。
如在相关技术中那样，由于LDC和48V电池管理模块是独立提供的，根据本发明的示例性实施方式，当车辆的点火装置被启动时，使用软件向起动发电机供应电压，从而移除向起动发电机供应电压传统所需的预充电继电器和充电电阻器，以减少用于构成系统的成本和工时。
图2是用于描述根据本发明的示例性实施方式的LDC集成电池模块的详细配置的图。
如图2所示，LDC集成电池模块300包括电池单元310、切换单元320、集成控制单元330以及冷却单元340。
电池单元310以48V的电压充电或放电。
切换单元320用于对在电池单元310中通过起动发电机100施加的48V的电压充电，并且执行切换操作，使得使用电池单元310的48V的电压来驱动发动机。
此外，当从12V电池200施加12V的电压时，集成控制单元330用于控制切换单元320，以对电池单元310进行充电和放电。
冷却单元340设置在电池单元310和集成控制单元330的板之间，并且用于对电池单元310和集成控制单元330进行冷却。
这里，集成控制单元330将LDC升压模式的输出电压与电池单元310的实际电压进行比较。当LDC升压模式的输出电压与电池单元310的实际电压之间的差大于或等于预设电压值时，集成控制单元330控制切换单元，使得在电池单元310中对48V的升压电压进行充电。
同时，当车辆的点火装置被启动并且施加12V的电压时，LDC集成电池模块300执行自诊断。
然后，当LDC集成电池模块300根据诊断的结果处于正常状态时，LDC集成电池模块300将12V的电压转换为48V的(LDC升压模式)电压，并且在起动发电机100的DC链路电容器(CAP)中对48V的电压进行充电。
同时，当LDC集成电池模块300根据自诊断的结果处于异常状态时，LDC集成电池模块300对异常情况的数量进行计数。当异常情况的数量达到预设的计数的数量时，LDC集成电池模块300操作警告灯并且停止将12V的电压转换为48V的电压的处理。
此外，当12V的电压被升压到48V的电压并且48V的电压在起动发电机100的DC链路CAP中被充电时，LDC集成电池模块300将值与48V的升压电压进行比较，其中，该值是通过将电池单元310的电压乘以DC链路CAP的充电电压的基准比而获得的。作为比较的结果，LDC集成电池模块300将48V的升压电压升压到一电平，在该电平下，将电池单元310的电压乘以DC链路CAP的充电电压的基准比而获得的值大于或等于48V的升压电压的输出电压。
当从设备管理控制器400输入LDC空闲模式请求时，LDC集成电池模块300停止将12V的电压转换为48V的电压(LDC升压模式)的操作。
在下文中，将参考图3描述根据本发明的示例性实施方式的用于48V轻度混合动力系统的LDC集成电池管理方法。
根据本发明的示例性实施方式的用于48V轻度混合动力系统的LDC集成电池管理方法由48V轻度混合动力系统执行，该48V轻度混合动力系统包括12V电池200、起动发电机100、包括电池单元310的LDC集成电池模块300以及设备管理控制器400。
首先，当车辆的点火装置被启动时，LDC集成电池模块300从12V电池200接收12V的电压(S100)。
接下来，LDC集成电池模块300执行自诊断并且确定是否发生问题(S200)。
当在操作S200中确定没有发生问题时(是)，LDC集成电池模块300将接收到的12V的电压升压到48V的电压(S300)。
然后，LDC集成电池模块300向起动发电机100施加48V的电压(S400)。
同时，LDC集成电池模块300根据48V的升压电压与用于48V的电池单元的电压之间的差来控制切换单元，以在电池单元中对48V的电压进行充电(S500)。
如在相关技术中那样，由于LDC和48V电池管理模块是独立提供的，根据本发明的示例性实施方式，因此当车辆的点火装置被启动时，使用软件向起动发电机供应电压，从而移除向起动发电机供应电压传统所需的预充电继电器和充电电阻器，以减少用于构成系统的成本和工时。
同时，当在操作S200中确定发生问题时(否)，LDC集成电池模块300对异常情况的数量进行计数(S600)。当异常情况的数量达到预设计数的数量时(是)，LDC集成电池模块300操作警告灯并且停止将12V的电压转换为48V的电压的处理(S700)。当异常情况的数量未达到预设计数的数量时(否)，处理返回到其中LDC集成电池模块执行自诊断的操作S200。
图4是用于描述根据本发明的示例性实施方式的向起动发电机100施加48V的电压的操作的流程图。
如图4所示，将48V的升压电压与通过将电池单元310的电压乘以DC链路CAP的充电电压的基准比而获得的值进行比较(S310)。
当48V的升压电压小于通过将电池单元310的电压乘以DC链路CAP的充电电压的基准比而获得的值时，48V的升压电压被升压到通过将电池单元310的电压乘以DC链路CAP的充电电压的基准比而获得的值(S320)。
当48V的升压电压大于或等于通过将电池单元310的电压乘以DC链路CAP的充电电压的基准比而获得的值时(是)，LDC集成电池模块300控制切换单元，以控制用于48V的电池单元的充电和放电(S330)。
同时，在起动发电机100的DC链路CAP中对48V的电压进行充电的操作中，当从设备管理控制器400输入LDC空闲模式请求时，LDC集成电池模块300停止将12V的电压转换为48V的电压(LDC升压模式)的操作。
根据本发明的示例性实施方式，可以使用单个控制器以软件方式控制LDC和LDC集成电池管理系统的电池单元，以提供用于对传统的轻度混合动力系统的MHSG预充电的继电器和充电电阻器的功能，从而移除用于对MHSG预充电的部件以降低成本和工时。
尽管上面已经参考附图详细描述了本发明的配置，但是这些仅仅是示例，并且本发明所属技术领域的普通技术人员可以在本发明的技术精神内进行各种修改和改变。因此，本发明的范围不应受上述示例性实施方式的限制，而应由以下权利要求确定。
