具体实施方式
根据本公开，一种电池组包括：彼此串联连接的多个电池单元；连接在多个电池单元中的两个之间的熔断器；以及被配置为测量多个电池单元的电压并根据测得的电压中的最高电压来控制熔断器的保护操作的初级保护电路。
另外，电池组可以进一步包括：可以连接至多个电池单元的整体正(+)端子或整体负(-)端子的充电开关和放电开关；以及被配置为控制充电开关和放电开关的开关操作的主控制单元。
另外，当可以检测到充电停止电压时，主控制单元可以输出用于关断充电开关的控制信号，并且当控制信号可以被输出之后测得的电压增大时，初级保护电路可以断开熔断器的连接。

另外，次级保护电路可以测量多个电池单元的电压，并且当测得的电压中的最高电压等于或大于第二截止电压时可以断开熔断器的连接。
另外，第二截止电压可以大于第一截止电压，并且熔断器可以连接在第一电池单元和第二电池单元之间。
在下文中，将参考附图详细描述示例实施例。然而，本公开可以以各种其他实施例实现，并且不限于本文描述的实施例。提供这些实施例的目的在于使本公开全面且完整，并且向本领域技术人员充分传达本公开的范围。
在下面的描述中，术语仅用于解释特定实施例，而不限制本公开的范围。除非另外提及，否则单数形式的术语可以包括复数形式。应该理解的是，当在本文中使用时，诸如“包含”、“包括”和“具有”的术语指明存在所述的特征、整体、步骤、操作、元件、部件或其组合，但不排除存在或添加一个或多个其他特征、整体、步骤、操作、元件、部件或其组合。应该理解的是，虽然本文中使用术语“第一”和“第二”描述各种元件，但这些元件不应当受这些术语的限制。这些术语仅用于将一个元件与另一元件区分开来。
在下文中，将参考附图详细描述示例实施例。在本公开中，相同的附图标记指示相同的元件。在附图中，相同或对应的元件用相同的附图标记指示，并且将不再重复描述。
图1是示出根据本公开的实施例的电池组100的配置的示意图。
参考图1，根据本公开的实施例，电池组100包括多个电池单元110-1至110-n、熔断器120和初级保护电路140。多个电池单元110-1至110-n彼此串联连接，熔断器120连接在多个电池单元110-1至110-n中的两个之间以对电池组100执行保护操作。
初级保护电路140测量多个电池单元110-1至110-n中的每一个的电压，并且根据测得的电压中最高电压的大小来控制熔断器120的保护操作。初级保护电路140可以包括连接至多个电池单元110-1至110-n中的每一个的电压测量单元和比较单元，以测量多个电池单元110-1至110-n的电压并比较测得的电压。
初级保护电路140将测得的电压中的最高电压与预设的第一截止电压进行比较，并且当结果示出最高电压等于或大于第一截止电压时，初级保护电路140可以通过输出控制信号来断开熔断器120的连接。
在本公开的实施例中，熔断器120可以连接在第一电池单元110-1和第二电池单元110-2之间，并且当熔断器120的连接被断开时，第一电池单元110-1和第二电池单元110-2之间的连接也断开，使得放电和充电可以停止。
因此，在根据本公开的实施例的电池组100中，当在充电操作期间由于过充电而导致单元电压等于或大于特定值时，熔断器120至电池单元的连接被断开以防止由过充电引起的问题。
此外，根据本公开的实施例，如图1中所示，电池组100可以进一步包括主控制单元(MCU)150、充电开关131和放电开关132。
充电开关131和放电开关132可以连接至多个电池单元110-1至110-n的整体正端子B+或整体负端子B-以及MCU 150，以根据来自MCU 150的控制信号执行开关操作。基本上，充电开关131和放电开关132可以通过开关操作来控制多个电池单元110-1至110-n的充电和放电，并且像初级保护电路140一样，MCU 150可以测量多个电池单元110-1至110-n的电压。
另外，MCU 150可以将多个电池单元110-1至110-n的电压与预设的放电停止电压和充电停止电压进行比较，并且可以通过使用充电开关131和放电开关132来控制电池充电和放电操作。
然而，由于MCU 150或者充电开关131和放电开关132的故障，充放电控制可能无法正确执行，并且在这种情况下，初级保护电路140可以控制熔断器120的连接以防止由过充电引起的问题。
因此，当即使在MCU 150检测到与充电停止电压对应的电压并输出用于关断充电开关131的控制信号之后电池单元电压也增大至第一截止电压或更高时，初级保护电路140可以输出用于断开熔断器120的连接的信号。
由于在MCU 150的充电停止操作之后，初级保护电路140控制熔断器120的连接，因此可以理解，充电停止电压低于第一截止电压。
图2是示出根据本公开的实施例的初级保护电路140的配置的示意图。
参考图2，根据本公开的实施例，初级保护电路140可以连接至多个电池单元110-1至110-n中的每一个的正(+)端子和负(-)端子，并且可以测量多个电池单元110-1至110-n中的每一个的电压。另外，熔断器120可以连接在多个电池单元110-1至110-n中的两个之间，并且可以对电池组执行保护操作。
初级保护电路140可以将测得的多个电池单元110-1至110-n的电压中的最高电压与第一截止电压进行比较，并且当第一截止电压低于最高电压时，初级保护电路140可以断开熔断器120的连接以保护电池组。
如参考图1所描述的，熔断器120在图2中被示出为连接在第一电池单元110-1和第二电池单元110-2之间，但是本公开不限于此配置。
另外，由于多个电池单元110-1至110-n以及熔断器120彼此串联连接，所以即使当熔断器120连接在多个电池单元110-1至110-n之间的任何位置时，断开熔断器120的连接也导致断开多个电池单元110-1至110-n的整个连接，从而使得可以执行足够的保护操作。
图3是示出根据本公开的另一实施例的电池组200的配置的示意图。
参考图3，根据本公开的另一实施例，电池组200包括多个电池单元210-1至210-n、熔断器220以及初级保护电路240。如参考图1和图2描述的，多个电池单元210-1至210-n彼此串联连接，并且熔断器220连接在多个电池单元210-1至210-n中的两个之间，以执行对电池组200的保护操作。
另外，电池组200进一步包括次级保护电路260。次级保护电路260与初级保护电路240并联连接，并且像初级保护电路240一样对电池组200执行保护操作。
具体地，次级保护电路260测量多个电池单元210-1至210-n中的每一个的电压，并且将测得的电压中的最高电压与第二截止电压进行比较，并且当最高电压等于或大于第二截止电压时，次级保护电路260断开熔断器220的连接。
即使当初级保护电路240输出用于断开熔断器220的连接的信号时，熔断器220也可能由于系统错误或设备故障而无法正常断开，并且在这种情况下，电池单元的连接不会被断开，从而导致充电操作期间电池电压持续增大。
可以理解，次级保护电路260在这种情况下操作，并且因此，第二截止电压可以被设置为大于第一截止电压。
由于该配置，即使当初级保护电路240无法正常执行保护操作时，也就是说，即使当熔断器220的连接未被初级保护电路240断开时，对于电池组200的保护操作也可以由次级保护电路260来保证。
根据图3中所示的实施例的电池组200可以包括MCU 250、充电开关231和放电开关232。此外，在图1和图3中，附图标记p+和p-分别指电池组的正(+)端子和负(-)端子。
虽然本文已经描述了本公开的一些实施例，但是应当理解，可以在本公开的范围内做出各种其他实施例。另外，上述元件的未描述的等同形式也可以在本公开的范围内。因此，本公开的范围和精神应由所附权利要求限定。
