Description

智能电池箱及检测方法
本申请要求申请日为2018年7月27日的中国专利申请2018108472850的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及一种智能电池箱及检测方法。
背景技术
随着电动汽车越来越受到消费者的欢迎，作为电动汽车的动力来源，汽车电池保持稳定工作是电动汽车安全性能的关键。在将电池箱安装至车辆的过程中，由于换电设备的安装精度有限，可能会出现电池箱安装不到位、不可靠，换电失败，电池箱无法为车辆供电的情况。在车辆行进过程中，由于路面过于颠簸、或是电池箱与车体的连接机构连接不牢固，可以会出现电池箱掉落的情况。上述的情况一旦出现对于车辆，甚至是车上的人员而言都是十分糟糕、危险的。因此，监控电池箱是否安装到位、是否掉落均是十分必要的。
目前，在换电过程中，监控电池箱是否安装到位通常是由换电设备本身或其他电池箱以外其他设备实现的。而在换电后，监控电池箱是否掉落通常是通过车辆是否通电来判断的，若车辆无电，则说明电池箱掉落，若车辆有电，则说明电池箱未掉落。
上述的监控方式要么需要依靠换电设备实现，要么需要依靠车辆内的电路检测实现，而电池箱本身并不具备检测功能，十分不方便。

附图说明
图1为本发明实施例1的智能电池箱的示意框图；
图2为本发明实施例2的智能电池箱检测方法的流程图。
具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
实施例1
一种智能电池箱，如图1所示，包括：电池箱总成11、状态检测模块12和BMS 13。所述状态检测模块12设置于所述电池箱总成11上，所述状态检测模块12与所述BMS 13通信连接。其中，所述通信连接优选为有线通信连接。
所述状态检测模块12用于获取所述电池箱总成11的状态信息，并将所述状态信息发送至所述BMS 13。
本实施例中，所述电池箱总成11包括电池箱体和设置在所述电池箱体上的连接机构。本发明对所述电池箱体和所述连接机构的具体结构不做限定。
所述状态信息可以包括所述电池箱总成11在车辆上的位置信息。
其中，为了获取所述电池箱总成11在车辆上的位置信息，所述状态检测模块12具体用于：根据自身检测到的应力方向及应力大小，获取所述电 池箱总成11在所述车辆上的位置信息。
具体地，所述状态检测模块12可以包括第一状态检测单元121，所述第一状态检测单元121的传感头设置于所述连接机构上。
所述第一状态检测单元121可以用于：
在所述智能电池箱安装至所述车辆的过程中，通过所述传感头检测所述连接机构产生的应力方向及应力大小，若所述应力大小大于第一阈值且所述应力方向与所述智能电池箱的安装方向相同，则所述电池箱总成11在所述车辆上的位置信息为已到达安装预设过程的目标位置。其中，第一阈值为预设的经验值。
例如，车辆的底部设置有电池外箱，在所述智能电池箱安装至所述车辆的过程中，根据电池外箱结构的不同，安装预设过程可能会有所不同。
第一种安装预设过程为换电设备从车辆的下方向上举升所述智能电池箱，在此安装预设过程中，智能电池箱的安装方向向上，目标位置设置为电池外箱内的最顶部，在电池箱总成11到达目标位置后通过螺栓、螺母等连接机构将智能电池箱与电池外箱连接并固定在所述目标位置。在所述换电设备向上举升所述智能电池箱的过程中，所述第一状态检测单元121通过所述传感头检测所述连接机构产生的应力方向及应力大小，若所述应力大小大于第一阈值且所述应力方向向上，则说明所述电池箱总成11已到达设置在电池外箱内的最顶部的目标位置。
第二种安装预设过程分为两个阶段，第一阶段：换电设备从车辆的下方向上举升所述智能电池箱；第二阶段：换电设备在水平方向箱前移动所述智能电池箱。在第一阶段中，智能电池箱的安装方向向上，目标位置设置为电池外箱内的最顶部；在第二阶段中，智能电池箱的安装方向为水平向前，目标位置设置为电池外箱内的最前端(以车头方向为前)，在电池箱总成11到达第二阶段的目标位置后通过锁轴或其他连接机构将智能电池箱与电池外箱连接并固定在所述目标位置。在实施第一阶段的过程中，所述第一状态检测单元121通过所述传感头检测所述连接机构产生的应力方向及应力大小， 若所述应力大小大于某个阈值且所述应力方向向上，则所述电池箱总成11已到达设置在电池外箱内的最顶部的目标位置。在实施第二阶段的过程中，所述第一状态检测单元121通过所述传感头检测所述连接机构产生的应力方向及应力大小，若所述应力大小大于某个阈值且所述应力方向水平向前，则所述电池箱总成11已到达设置在电池外箱内的最前端的目标位置。
所述第一状态检测单元121还可以用于：
在所述智能电池箱安装至所述车辆后，通过所述传感头检测所述连接机构产生的应力方向及应力大小，若所述应力大小大于第二阈值且所述应力方向与重力方向相反，则所述电池箱总成11在所述车辆上的位置信息为已达到安装完成的目标位置。其中，第二阈值为预设的经验值。
还是以上述第一种安装预设过程为例，安装完成的目标位置设置为电池外箱内的最顶部。在所述智能电池箱安装至所述车辆后，若电池箱总成11已到达安装完成的目标位置，那么，由于电池箱总成具有一定的重量，所以连接机构会受到电池箱总成向下施加的重力，而为了支撑电池箱总成，连接机构会产生向上的应力，反之，若电池箱总成没有到达安装完成的目标位置，那么，连接机构就不会产生向上的应力或者即使产生应力，应力的大小也不足够。基于此，所述第一状态检测单元121的传感头设置于连接机构上，可以通过所述传感头检测所述连接机构产生的应力方向及应力大小，判断所述电池箱总成11是否已到达安装完成的目标位置，即若所述应力大小大于第二阈值且所述应力方向向上，则所述电池箱总成11已到达安装完成的目标位置。
以上述第二种安装预设过程为例，安装完成的目标位置设置为电池外箱内竖直方向上的最顶部，水平方向的最前端。在所述智能电池箱安装至所述车辆后，若电池箱总成11已到达安装完成的目标位置，那么，由于电池箱总成具有一定的重量，所以连接机构会受到电池箱总成向下施加的重力，而为了支撑电池箱总成，连接机构会产生向上的应力，反之，若电池箱总成没有到达安装完成的目标位置，那么，连接机构就不会产生向上的应力或者即 使产生应力，应力的大小也不足够。基于此，所述第一状态检测单元121的传感头设置于连接机构上，可以通过所述传感头检测所述连接机构产生的应力方向及应力大小，判断所述电池箱总成11是否已到达安装完成的目标位置，即若所述应力大小大于第二阈值且所述应力方向向上，则所述电池箱总成11已到达安装完成的目标位置。
进一步地，所述状态检测模块12还可以包括第二状态检测单元122，所述第二状态检测单元122的传感头设置于所述电池箱总成11与所述车辆的抵接面上。其中，所述抵接面根据所述电池箱总成11与所述车辆的抵接方式确定，具体的抵接方式可以为侧面抵接、顶面抵接等，相应的抵接面则为电池箱总成11的侧面、顶面等。
所述第二状态检测单元122用于：
在所述智能电池箱安装至所述车辆后，通过所述传感头检测所述抵接面产生的应力方向及应力大小，若所述应力大小大于第三阈值且所述应力方向为沿所述电池箱体向外的方向，则所述电池箱总成11在所述车辆上的位置信息为保持在安装完成位置并与所述车辆的紧密连接。其中，第三阈值为预设的经验值。
例如，所述智能电池箱安装至所述车辆后，电池箱总成11的前侧面与车辆内的电池外箱相应的前内侧面抵接，电池箱总成11的顶面与车辆内的电池外箱相应的顶内侧面抵接，则若设置于电池箱总成11的前侧面的第二状态检测单元122若通过传感头检测到前侧面产生的应力大小大于相应的阈值且所述应力方向为沿所述电池箱体向外的方向(即向前)，且设置于电池箱总成11的顶面的第二状态检测单元122若通过传感头检测到顶面产生的应力大小大于相应的阈值且所述应力方向为沿所述电池箱体向外的方向(即向上)，则所述电池箱总成11在所述车辆上的位置信息为保持在安装完成位置并与所述车辆的紧密连接。
所述状态信息还可以包括所述电池箱体的温度信息。防止电池过热而造成损坏。
为了同时实现应力检测和温度测量，本实施例中，所述状态检测模块12可采用光纤光栅传感器实现。光纤光栅传感器利用部分物质吸收的光谱随温度变化而变化的原理，分析光纤传输的光谱了解实时温度。
另外，为了便于查看、分析状态信息，所述BMS 13用于存储所述状态信息，并记录所述状态信息的接收时间。
为了便于所述状态信息的传输和监控，所述智能电池箱还包括通讯模块14；
所述通讯模块与所述BMS 13通信连接，所述BMS 13通过所述通讯模块将所述状态信息发送至远程监控设备。
所述智能电池箱还包括数据传输接口；
所述数据传输接口15与所述BMS 13通信连接，所述BMS 13通过所述数据传输接口将所述状态信息发送至VCU或接入所述数据传输接口的设备。
本实施例的智能电箱不需要依靠电池箱以外的其他设备即能检测自身的状态，例如，电池箱总成11是否已到达安装预设过程的目标位置、是否已到达安装完成的目标位置、是否保持在安装完成位置并与车辆紧密连接。一方面能够即使检测到电池箱状态，另一方面，也能够简化车辆或其他设备的检测电路。
