Description

用于监测车辆的电池的方法和装置
技术领域
本发明涉及一种用于监测车辆的电池的方法。
本发明还涉及一种用于监测车辆的电池的装置。
背景技术
本发明在面对无法启动的车辆时为机修工或操作员提供决策辅助方面和在通知驾驶员或车辆使用者与车辆的电池相关的异常方面是特别有用的。
本发明还对于给机修工、操作员、使用者或车辆驾驶员发送与用于启动车辆的电池的状态相关的警告、警报或指示是特别有用的。
如果发生使车辆不能移动的故障，机修工或操作员可能面对许多车辆不能移动情况。
如果发生阻止车辆立即启动的故障，则操作员或机修工因此不能容易地确定是否将现有电池替换成新电池，或者如果现有电池经受深度放电则是否仅需要对其充电。
一般而言，当没有足够的信息时，使操作员或机修工将现有电池替换成新电池，以便允许车辆快速启动和避免在不久的将来不能移动。然而，已经发现，在四分之三情况下，电池仅仅经受了不证明其替换是正确的深度放电。
另外，在停车情况下，驾驶员或使用者可能忘记关闭前照灯或另一个耗电装置，这导致电池逐渐放电，甚至导致车辆不能移动，从而阻止车辆的后续启动。
并且，在不消耗电流的休眠车辆情况下，车辆内的故障可能导致不期望的电池放电。
因此，需要监测车辆的电池以避免用新电池进行不必要的替换，并且允许使用者或驾驶员校正可能导致车辆不能移动的电池放电状况。
发明内容
本发明的第一目的是通过提出一种用于监测车辆的电池、使得可以避免或补救车辆不能移动的新方法来克服现有技术的缺点。
本发明的另一个目的是提供一种用于监测车辆的电池、使得可以避免或补救车辆不能移动的新装置。
本发明涉及一种用于监测车辆的电池的方法，该方法包括以预定时间间隔测量该电池的电量状态的连续步骤，其特征在于，该方法进一步包括将该电池的电量状态的测量值与预定阈值进行比较的步骤和将低于所述预定阈值的测量值的数量与预定数量比较的步骤，以决定是替换该电池还是对其充电，从而避免或补救车辆不能移动。
根据本发明的其他替代性特征：
-该方法包括确定该车辆的状态以确定该车辆是否电休眠的步骤。
-该方法包括给该车辆的驾驶员或使用者发送警报、例如电子邮件、文本消息或任何其他类型的警告消息的步骤。
-该方法包括确定是否可以使用诊断器对该车辆的电池进行诊断的步骤。
-该方法包括确定和测试该电池的最后开路电压OCV值以了解这些最后开路电压值是否明显高于零伏的步骤。
-该方法包括控制该电池在无负载下的电量状态的最后记录日期以确定是否应对该电池充电或是否应将该电池替换成新电池的步骤。
-该方法包括控制其中该电池的电量状态的所记录的测量值小于预定数值以确定是否应对该电池充电或是否应将该电池替换成新电池的步骤数量的步骤。
本发明还涉及一种用于监测车辆的电池的装置，该装置包括以预定时间间隔连续测量该电池的电量状态的器件，其特征为用于将该电池的电量状态的测量值与预定阈值进行比较的器件和用于将低于所述预定阈值的测量值的数量与预定数量比较的器件，以决定是替换该电池还是对其充电，从而避免或补救车辆不能移动。
根据本发明的其他替代性特征：
-该装置包括能够与诊断器连接并且与电信控制单元连接的CAN通信总线，所述电信控制单元能够给驾驶员或车辆使用者的接收器发出警报。
-该装置包括将电功率管理计算机与车辆的电池连接的LIN通信总线。
附图说明
从通过非限制性实例并且参照附图给出的以下说明中将更好地理解本发明，在附图中：
图1示意性表示用于监测车辆的电池的方法的流程图。
图2示意性表示用于监测车辆的电池的另一种方法的流程图。
图3示意性表示用于监测车辆的电池以实施图1或图2中根据本发明的监测方法之一的装置。
具体实施方式
在图1中，用于监测车辆的电池的方法从步骤100开始，在该步骤中，使车辆停止，意味着车辆的内燃发动机停机。
该方法在步骤101继续进行，检查车辆的状态以确定该车辆是否处于“休眠模式”。
如果此车辆是处于通过停止所有可能使车辆的电池放电的耗电的待命状态，车辆的状态可以被描述为处于“休眠模式”。
如果在步骤101发现车辆处于休眠模式，则该方法继续进行到步骤102。
在步骤102中，测量与开路电压OCV相对应的数据，这个测量的开路电压OCV数据被记录在车辆的电功率管理计算机中。
在步骤102中，开路电压OCV数据还与例如大约12伏的第一预定阈值比较。
如果开路电压OCV大于所述预定阈值，则该方法循环回到检查车辆状态的步骤101。
如果开路电压OCV小于所述预定阈值，则进行到给驾驶员或给车辆的使用者发送警报的步骤104。该警报可以通过SMS文本消息发送给驾驶员或车辆的使用者的移动电话或智能电话。
在不脱离本发明的范围的情况下还可以考虑任何其他警报模式，诸如语音消息、电子邮件消息、或能够在车辆的使用者或驾驶员的接收器上接收到的任何其他类型的传输。
如果在步骤101发现车辆没有处于休眠模式，即，仍然耗电，特别是在电气故障情况下，在步骤103进行仪表检查。
仪表检查是在车辆的电功率管理计算机中可获得的测量数据。这种仪表检查与车辆的电池的电量状态相对应。步骤103的仪表检查允许在电功率管理计算机可获得的数据与另一个预定阈值(例如，大约7伏)比较。
如果步骤103确定电池的电量状态SOC的值小于所述其他预定阈值的所述预定值，则进行到给驾驶员或给车辆的使用者发送警报的步骤104。
这个步骤104与如上所述通过SMS文本消息或任何其他警报模式(诸如语音消息、电子邮件消息)或能够在车辆的使用者或驾驶员的接收器上接收到的任何其他类型的传输来给驾驶员或车辆的使用者的接收器发送警报相对应。
如果步骤103中的仪表检查确定车辆的电池的电量状态SOC大于所述另一个预定阈值的所述预定值，则该过程循环回到确定车辆状态的步骤101。
在图2中，用于监测车辆的电池的另一种方法从步骤200开始，在该步骤中，使车辆停止，意味着使车辆的发动机熄火。
在步骤200情况下，车辆可能由于不能启动而不能移动，即，内燃发动机不再能独立启动。
进行到检查是否可以使用已知类型的、常常被专家称为“夹盒(valise Clip)”的诊断器进行诊断的步骤201。
如果步骤201得出发现：使用夹盒进行诊断是可能的，则执行经由夹盒读取车辆的电功率管理计算机的内部存储器的步骤204。
在步骤204，诊断器读取车辆电池状态SOC的预定数量的记录值，例如，以大致两小时的时间间隔读取所记录的最后十二个值。
电功率管理计算机记录的最后值的读取允许记录值与电池的电量状态SOC的预定阈值(例如，大约12伏)比较。
通过提取低于这个预定阈值的值并且记录低于所述预定阈值(例如，大约12伏)的这些值的数量来进行这种比较。
在步骤205，低于所述预定阈值的记录值的数量与预定数量(例如，记录值的总数的一半)比较。
在本实例中，检查以确定在最后十二个测量值当中低于所述预定阈值的测量值的数量是否少于六个，记录在电功率管理计算机中。本发明不局限于通过非限制性实例给出的值、阈值和数量，并且相反扩展至符合根据本发明的验证方法的所有其他数量、值或阈值。
如果在步骤205发现低于预定阈值的测量值的数量少于固定预定数量，则进行到电池充电步骤206。
如果低于所述预定阈值的测量值的数量大于所述预定数量，则进行到包括将电池替换成新电池的步骤209。
在步骤201，如果发现车辆的诊断使用夹盒是不可能的，则进行到使用外部电池启动车辆、或通过将车辆与外部电池或其他电启动装置来启动车辆的步骤202。
在步骤202启动车辆之后，进行到使用夹盒检查电池以验证电功率管理计算机中所记录的值的步骤203。
根据开路电压OCV值检查步骤203中记录的值。
如果在步骤203发现最后的开路电压OCV明显大于零伏，则进行到上述步骤204，接着进行到步骤205以直接到上述步骤206或步骤209。
如果步骤203中的检查确定最后的开路电压OCV接近于零伏，则进行到读取电功率管理计算机中记录的数据的步骤207。
在步骤207，诊断器读取车辆电池状态SOC的预定数量的记录值，例如，以大致两小时的时间间隔读取所记录的最后十二个值。
步骤208中的检查允许最后的开路电压OCV记录日期与预定阈值(例如，十二个小时)比较。
如果步骤208中的检查使得可以确定最后的开路电压OCV记录日期小于预定日期，例如，小于12个小时，则进行到电池充电步骤206。
如果在步骤208的检查显示最后的开路电压OCV记录日期大于预定日期，例如，大于十二个小时，则进行到将电池替换成新电池的步骤209。
在图3，根据本发明的电池监测装置包括机修工的夹盒或诊断器1。
诊断器1经由CAN通信总线2与电功率管理计算机3连接。
传递通过CAN通信总线2的一部分的数据主要是测量的电池电量状态或电池开路电压值的时间数据和读取数据。
电功率管理计算机3通过LIN通信总线与车辆的电池B通信。
由于电池B递送的电流的作用，这条LIN通信总线4允许电功率管理计算机3记录电池的电量状态SOC。
电功率管理计算机3还允许电池的电量状态SOC与任意选择的预定阈值比较，以实施参照图1所描述的方法或参照图2所描述的方法。
借助于滑动时间窗口使测量值和记录值按照电功率管理计算机3中的测量日期来排序，电池的电量状态SOC被存储或记录在功率管理计算机中。
与仪表检查相对应、和与开路电压OCV检查相对应的值被记录或存储在电功率管理计算机3中。
电功率管理计算机3还经由CAN通信总线2与能够给具有接收单元6(例如，便携式装置、智能电话或移动电话)的用户和车辆驾驶员递送无线消息或警报的电信和控制单元5连接。
在开路电压OCV低于预定阈值的情况下或如果仪表检查揭示低于另一个预定阈值的值，通过CAN通信总线2在电功率管理计算机3与电信和控制单元5之间进行通信以实施参照图1所描述的根据本发明的方法。
参照具体实施例描述的本发明决不局限于这些具体实施例，而是相反，涵盖所附权利要求书的范围和精神内的任何设计修改和任何替代性实施例。
