请参阅图 1至图 3， 其为本发明的第一实施例。 本实施例为一种接头组， 其中包含： 一电极 101、 一电极螺栓 102、 一固定槽 103、 一电极螺牙 104、 一固定螺栓 105、 一固 定螺牙 106、 一电流导体 110、 一第一接触点 111、 一第二接触点 112、 一第一绝缘套管 113、 一第二绝缘套管 114、 一绝缘护套 115、 一弹性垫片 116。
如图 2所示， 电极 101 具有电极螺牙 104 与固定螺牙 106。
电流导体 110 通过电极螺栓 102 被锁于电极 101 上， 其中， 电极螺栓 102 被调整 至一位置使固定槽 103 与固定螺牙 106 对齐， 以安装固定螺栓 105。
固定螺栓 105 是用于将一组检测传感器组固定至固定螺牙 106 上。 检测传感器组， 包含一绝缘护套 115 、 一第一接触点 111、 一第二接触点 112、 一 弹性垫片 116; 如图 3中第一实施例所示， 绝缘护套 115 包含第一接触点 111 与第二接 触点 112; 当绝缘护套 115 被固定螺栓 105 所挤压时， 弹性垫片 116 压缩使第一接触 点 111 与第二接触点 112 彼此碰触并产生电路连结； 当绝缘护套 115 被释放或是解压 时， 弹性垫片 116 会将第一接触点 111 与第二接触点 112 撑开并隔绝其电路连结。
在第一实施例中， 第一接触点 111连接至一电池管理单元， 第二接触点 112连接至 一用以接收来自电极的电压信号的电压感测探针或是电压感测接头， 如此， 电池管理单元 会于第一接触点 111 与第二接触点 112 相连结时持续接受到一稳定的电压信号，且会在 第一接触点 111 与第二接触点 112 被隔绝开时失去电压信号。
现在参阅图 4， 其为本发明案第二实施例， 其中， 数组检测传感器组被安装至第一电 池 401 与第二电池 402， 其中， 第一电池 401 与第二电池 402 并联。
第二实施例公开两个电池被并联时，使用多组检测传感器以传入一组电压信号来检测 多个电极的锁固状态的方法，其特征在于，第一电池 410 的负极 412 与第二电池 420 的 负极 421具有同样的电位。
固定螺栓 414 是用来确认第一电池 410 的负极 412 上的电极螺栓 413 的锁固状 态， 其特征在于， 固定螺栓 414 上亦固定了一检测传感器组件， 如第一实施例所描述， 安装于第一电池 410 的负极 412 的固定螺牙上。
固定螺栓 424 是用来确认第二电池 420 的负极 421 上的电极螺栓 423 的锁固状 态， 其特征在于， 固定螺栓 424 上亦紧锁了一检测传感器组件， 如第一实施例所描述， 安装于第一电池 420 的负极 421 的固定螺牙上。
一电压的信息信号， 来自于第一电池的负极与第二电池的负极， 会被传输至电流导体 450 至输入线 452; 当这两个与固定螺栓 414 与固定螺栓 424 相关联的检测传感器组件 被挤压至使一电流得以通过第一接触点与第二接触点时，该电流信息信号会被传输经过输 入线 452、 互联接线 451、 及电池管理单元 (；未显示)的输出线 453， 从而向电池管理单元 回报此一电压信息。
当其中一检测传感器组件因为相关联的固定螺栓的松脱而导致丧失挤压状态，该传感 器的第一接触点与第二接触点的电传导会被破坏， 在此情况， 电池管理单元便会丧失其电 压信息信号， 因此， 车辆管理单元便能利用电压信息信号的丧失作为电极连结的松脱潜在 可能性的指示，则与电池管理单元关联的车辆管理单元便能通知使用者或是服务人员对该 电极连结做必要的检测。
现在参阅图 5， 其显示了第二实施例的进阶应用范例， 其特征在于； 方块 504、 503、 502与 501分别代表了一检测传感器组件， 其用以回报其对应电池电极的锁固状态以及该 并联电池组的指定节点的电压信息信号； 配线 534、 533、 532与 531被用以连接个别的相 应电极的检测传感器组件。
在图 5中， 偏压电阻 523、 522 和 521 被用于产生一分压器电路， 其能够检测多个 电池电极的锁固状态且在任何电池的电极螺栓松脱时辨识故障的电极连结， 其特征在于； 在所有的检测传感器组件皆被紧锁的状态下， 电池管理单元在在下直接通过连接线 520 和 534 来读取电压信息信号， 获得电极电路节点的全电压值； 如当其中一检测传感器组 件松脱， 则连结线 520 与 534 的电路无法导电， 电池管理单元会通过相对应的偏压电阻 来读取该电极电路节点的电压信息信号， 而获得一折减后的电压值， 因此与电池管理单元 关联的车辆管理单元借由被折减的电压信号和计算分压电路的电压值，可以判定且辨认该 连结故障的特定电极。
通过如图 5所示的实施例的实施，车辆管理单元可以在电极或电流导体的脱落发生的 前向使用者通知故障的电极连接， 因为即使车辆管理单元自折减的电压信息值辨认出松脱 的固定螺栓， 其电极螺栓应仍然位于其电极螺纹内， 因此， 其向驾驶或服务人员提供了一 对故障接点进行检测的预警。
