Description

一种利用电池传感器以检测多个电极的锁固状态检测装置
技术领域
本发明涉及一种利用电压传感器以检测一个电池组中多个电极接点锁固状态的装置，更切确而言是一种利用电压传感器的信号一致性以确认锁固状态的装置；该锁固状态确认的装置在电动车辆领域特别有用，因为在此领域大量的电池模块常被相互连接使用以提供电力，而相关联的电极螺栓会受到车辆震动的影响。
背景技术
大型电动车辆组电池组经常需要使用数以百计的电芯；以并联或串联方式连接。大多的装配方式无法准确的锁紧每个接点，导致此类电池组一直存在松脱的风险；然而，在行进的过程当中，电池亦不断的受到车辆持续震动的影响，因此当电动车辆行驶长时间运行时，有可能导致电池接点松脱，并产生高压电弧或是火花。因此，当电池被安装于车辆时，有必要设置一种电池锁固状态的检测装置以确保电池组的安全。
发明内容
本发明提供一种锁固状态检测装置，该装置包含一检测传感器组件用以回传电池电压信息与电池组上多个电极接点的锁固状态，尤其用于会受到持续震动的电动车辆。
本发明的主要目的在于提供一种锁固状态检测装置，能在在电极接点出现有松脱的潜在可能时提醒使用者对其进行检测，从而防止电动车辆的电力系统发生故障。
本发明的次要目的在于提供一锁固状态的检测装置，能够将电池接点的锁固状态以及电池电压信息传递给电池管理单元。
本发明的另一目的在于提供一锁固状态的检测装置，能够以一个电池管理单元的电压传感器检测多个具有同样电位的不同电极的锁固状态。
为达上述目的，本发明的一较广义实施态样为提供一种多个电极接点的锁固状态确认装置，其包含：一电极，具有一电极螺牙与一固定螺牙；一电极螺栓，用以锁固一电流导体与该电极螺牙，其特征在于，该电极螺栓具有至少一固定槽；一感测单元，其包含一绝缘护套、一第一接触点、一第二接触点、一弹性构件与一电压信号输入接头，用于在该弹性构件被挤压时形成一电流通路以回报该电极的电路节点的电压信号；以及一固定螺栓，用于固定一检测传感器组于该固定螺牙的上，当该固定螺栓的头段位于该电极螺栓的该固定槽中，借由该固定螺栓的螺栓头段对该电极螺栓形成一锁固状态。
根据本发明的构想，该锁固状态检测装置进一步包含与该电极同一电位的个别额外电极的额外检测传感器组件。
根据本发明的构想，该锁固状态确认装置还包括至少一偏压电阻以形成一分压电路，该检测传感器组件的弹性构件不受到挤压时，会产生一独特的电压下降的电压信号传递至电池管理元件。
根据本发明的构想，该锁固状态确认装置还包括一控制元件以通过测量该独特的电压下降以辨认故障的电极接点。
为达上述目的，本发明的另一较广义实施态样为提供一种包含至少两个检测传感器组与一电压信号传入连接器以检测多个电极的电路节点的故障电极接点的锁固状态确认装置，其特征在于，个别检测传感器组包含一绝缘套件、一第一接触点、一第二接触点与一弹性构件，在该弹性构件受到固定螺栓与相关连的电极螺栓锁固挤压时形成一电流通路通过该第一接触点与第二接触点。

具体实施方式
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件固定至固定螺牙106上。
检测传感器组件，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，数组检测传感器组件被安装至第一电池410与第二电池420，其中，第一电池410与第二电池420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组件以传入一组电压信号来检测多个电极411、412、421、422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511、512、513、514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。
