本申请要求申请日为2021/12/2的中国专利申请CN2021115158982的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及换电站,特别涉及一种换电站内的热失控电池的处置方法。
背景技术
电动汽车具有零排放、低噪音、运营和维护都十分经济等优点,越来越受到用户的青睐。电动汽车使用的能源为自身搭载的动力电池组提供的电能,电动汽车在电能使用完后需要充电。由于现有的电池技术和充电技术的限制,电动汽车充满电需要花费较长时间,不如燃油汽车直接加油简单快速。因此,为了减少用户的等待时间,在电动汽车的电能快耗尽时更换电池是一种有效的手段。为了便于给电动汽车更换电池,满足电动汽车的换电需求,需要建造换电站,随着电动汽车的快速普及,需要建造更多的换电站来满足需求。
换电站一方面用于存贮若干个电池,满足电动汽车的快速换电需求,另一方面也用于为更换下的电池进行维护和充电。但是在存储或进行充电的时候,极个别电池会出现问题而产生高温,并释放出有毒气体,甚至会引发火灾或爆炸。目前,针对这类安全失控的电池,需要通过码垛机将失控电池从充电架上取下并转运给换电小车,然后通过换电小车自换电站的入户门快速转运至换电站的外部,进行安全处理。由于充电架和码垛机设置在换电站的内部,且远离入户门设置,需要通过换电小车运送至换电工位区域再由人工协助将热失控电池转移至换电站外,导致电池转运费时、费力,增大了换电站的安全风险。
发明内容
本发明要解决的技术问题是为了克服现有技术中的热失控电池的处置方法安全风险大的缺陷,提供一种换电站内的热失控电池的处置方法。
本发明是通过下述技术方案来解决上述技术问题:

所述监控系统确认所述热失控电池的位置,并控制码垛机从电池架取出所述热失控电池;
所述监控系统控制所述码垛机执行预设操作,使得所述热失控电池直接穿过设于所述换电站的侧壁上的应急出口转运至换电站的外部。
在本方案中,该处置方法通过温度检测设备检测电池的温度,并将电池的温度发送给监控系统,监控系统根据预设阈值确认出温度超标的热失控电池的位置,并控制码垛机通过换电站侧壁上的应急出口直接将该热失控电池转运至换电站的外部,由于码垛机可以直接执行完成将热失控电池从侧壁的应急出口转移出换电站的动作,使得热失控电池可以快速被转移到换电站外,无需由码垛机转移给换电小车,再由换电小车运送至换电工位后由人工将热失控电池转移至站外,大大缩短了热失控电池被转移的路径,从而提升了热失控电池的转移速度和提高了换电站的安全性。另外,该处置方法利用温度检测设备实时检测电池温度,监控系统实时监测温度并识别出热失控电池,再通过码垛机直接将失控电池转移至换电站外,实现了换电站内部电池温度的实时检测和对热失控电池的自动化处理,整个处置过程无需其他设备协作和人工干预,进一步使得热失控电池转移快速以及提高换电站的安全性。

具体实施方式
下面通过实施例的方式并结合附图来更清楚完整地说明本发明,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
如图1-图4所示,本发明公开了一种换电站内的热失控电池的处置方法,该处置方法应用于下述的换电站。在换电站的中部设置有换电室2,在换电室2的两侧分别设置有一个充电室1。换电室2用于承载待更换电池的电动汽车,电动汽车驶入并停靠于换电室2,再由换电设备拆卸电动汽车上待充电的旧电池并安装充满电的新电池,换电设备在拆卸下电动汽车上的旧电池后,将其运输到充电室1中进行充电。
如图2-图4所示,换电站的充电室1内并排设置有电池架11和码垛机12,并且换电站的侧壁上设置有应急出口13。设有应急出口13的侧壁与码垛机12相邻,以便于码垛机12通过自身的伸出机构从电池架11取出热失控电池后,伸出机构载着热失控电池从应急出口13伸出,直接将热失控电池转运至换电站的外部,缩短热失控电池的转运路径,减少转运时间,提高换电站的安全性。
如图1所示,热失控电池的处置方法包括如下步骤:
S100、温度检测设备检测电池的温度并发送给监控系统,当电池的温度超过预设阈值时,监控系统将其确认为热失控电池并报警,
在该步骤中,本实施例设置有两种温度检测设备,其分别为电池的电池管理系统和光纤测温传感器,这两种温度检测设备均能够对电池进行温度检测,并能够相互印证热失控电池的温度,以提高温度检测的准确性,避免误报;以及,在其中一个发生故障而无法检测到温度,另一个可以继续检测,以避免漏报。其中,第一种电池温度检测设备为电池管理系统,电池管理系统为电池的一部分,用于实时监测电池的工作状态,比如电量、温度等信息。电池管理系统能够可与为电池充电的电连接装置交互信息,电连接装置从电池管理系统获取电池的温度后发送给监控系统,监控系统收到电池的温度值后,与系统内设置的预设阈值进行比对。若电池的温度值超过预设阈值时,将该电池确认为热失控电池并报警。
第二种电池温度检测设备为光纤测温传感器,光纤测温传感器可布设在电池的上方或下方以检测电池的温度并发送给监控系统。当监控系统收到电池的温度值后,与系统内设置的预设阈值进行比对,若电池的温度值超过预设阈值时,将该电池确认为热失控电池并报警。此处利用光纤测温传感器测量精度高、抗电磁干扰、安全防爆、可绕性好的优点,对电池进行实时测温,并能够与电池管理系统相互印证热失控电池的温度,以提高温度检测的准确性。
在另一个实施例中,温度检测装置可以只采用电池管理系统和光纤测温传感器中的一种。
预设阈值可设置为任意一温度值,通常设置的温度值不低于50°,在本实施例中,预设阈值设置为60°。报警的方式可采用声光报警器报警。
在步骤S100之后,还包括步骤S1001:确认热失控电池的温度,若热失控电池的温度超过预设阈值,则确认报警为真,暂停换电;否则排出报警。在本实施例中,通过进一步确认电池的温度,提高报警的准确性,排除误报 情况,避免由误报导致后续造成损失。
在其他的实施例中,也可通过其他智能检测设备采集电池的温度数据,并进行相互比对,通过智能控制系统自动确认。
S200、监控系统确认热失控电池的位置,并控制码垛机12从电池架11取出热失控电池。
在该步骤中,可通过电池管理系统确认热失控电池的位置。由于电连接装置设置在存放电池的电池仓位内,并且电连接装置与电池仓位具有一一对应关系,监控系统根据热失控电池当前电连接的电连接装置确定热失控电池所在的电池仓位,以识别出热失控电池的位置。
或者,可通过光纤测温传感器确认热失控电池的位置。由于光纤测温传感器设置在存放电池的电池仓位内,并且光纤测温传感器与电池仓位具有一一对应关系,监控系统根据光纤测温传感器确定热失控电池所在的电池仓位,以识别出热失控电池的位置。
在该步骤中,码垛机12受监控系统控制,当监控系统识别出热失控电池的位置后,监控系统控制码垛机12的伸出机构从电池架11上取下热失控电池。
S300、监控系统控制码垛机12执行预设操作,使得热失控电池直接穿过设于换电站的侧壁上的应急出口13转运至换电站的外部。
在本实施例中,在热失控电池穿过应急出口13的同时,打开应急出口13,以减小因打开应急出口13造成的时间延迟,提高对热失控电池的转运效率。
在其他可替代的实施例中,也可在热失控电池穿过应急出口之前,打开应急出口。
具体的,在应急出口13的邻近位置设置有触碰开关,触碰开关将封闭应急出口13的门体131锁定和解锁,触碰开关只需轻微触碰就能够解锁,而不需要复杂的解锁程序,用于在突发情况时,需要快速开启应急出口13的 场景,以减小因开启应急出口所花费的时间;而且触碰开关的可靠性高,封闭应急出口的门体可以被即时有效的打开,从而确保热失控电池被转移至换电站外,提升换电站的安全性。在热失控电池穿过应急出口13的同时,码垛机12的伸出机构或载于码垛机12上的热失控电池触碰触碰开关解锁封闭应急出口13的门体131,打开应急出口13,无需人工操作,实现自动化操作。
在本实施例中,应急出口13的打开是在码垛机12的伸出机构或载于码垛机12上的热失控电池触碰触碰开关之后,用于封闭应急出口13的门体131在弹性元件的作用力下向远离所述应急出口的方向翻转打开应急出口13,开启方便、快速,而无需手动打开,提高转移热失控电池过程的效率和安全性。
在其他可替代的方案中,门体也可以采用平移滑动开启的方式。
在其他的实施例中,也可通过自动化的方式打开和关闭应急出口。应急出口的驱动机构受监控系统控制,用于打开封闭应急出口的门体,在热失控电池穿过应急出口之前,监控系统发送第一信号给应急出口的驱动机构,驱动机构收到第一信号后驱动封闭应急出口的门体打开应急出口,实现应急出口的自动打开,而无需人工干预,自动化程度高,提高对热失控电池的处置效率和安全性。
驱动机构还受监控系统控制,用于关闭封闭应急出口的门体,在热失控电池转移至换电站的外部之后且伸出机构收回至充电室的内部,监控系统发送第二信号给应急出口的驱动机构,驱动机构收到第二信号后驱动应急出口的门体封闭应急出口,实现应急出口的自动关闭,而无需人工干预,自动化程度高,同时提高热失控电池转移过程中的安全性。
热失控电池被转运至换电站的外部后,热失控电池被置于应急处理设备中,进一步由应急处理设备进行处置,使得热失控电池的状况避免进一步恶化,以及万一出现燃烧、爆炸等严重状况时,可减小热失控电池对周围环境 和设备造成的破坏。应急处理设备通常有水箱、沙坑或防爆罐体中的任一种。可将热失控电池淹没于应急处理水箱内的水中,对热失控电池降温和与氧气隔绝,防止热失控电池燃烧或爆炸。也可将热失控电池淹没于沙坑内的沙中,对热失控电池进行降温和与空气隔离,防止热失控电池燃烧或爆炸。防爆罐体也能够降低热失控电池在爆炸时对周围环境和设备造成的破坏。
在本实施例中,步骤S100、S200和S300的执行顺序可根据实际情况进行调整,此处不做具体限定。该处置方法通过温度检测设备检测电池的温度,并将电池的温度发送给监控系统,监控系统根据预设阈值确认出温度超标的热失控电池的位置,并控制码垛机通过换电站侧壁上的应急出口直接将该热失控电池转运至换电站的外部,由于码垛机可以直接执行完成将热失控电池从侧壁的应急出口转移出换电站的动作,使得热失控电池可以快速被转移到换电站外,无需由码垛机转移给换电小车,再由换电小车运送至换电工位后由人工将热失控电池转移至站外,大大缩短了热失控电池被转移的路径,从而提升了热失控电池的转移速度和提高了换电站的安全性。
另外,该处置方法利用温度检测设备实时检测电池温度,监控系统实时监测温度并识别出热失控电池,再通过码垛机直接将失控电池转移至换电站外,实现了换电站内部电池温度的实时检测和对热失控电池的自动化处理,整个处置过程无需其他设备协作和人工干预,进一步使得热失控电池转移快速以及提高换电站的安全性。
实施例2
本实施例与实施例1基本相同,其不同之处在于:电池架和码垛机并排设置于换电站的充电室内,侧壁上设置有应急出口,设有应急出口的侧壁与电池架相邻。电池架上设置有预设电池仓位,预设电池仓位与应急出口对应设置,且仅用于转移热失控电池。码垛机通过伸出机构从电池架取出热失控电池后,先将热失控电池转移至预设电池仓位,伸出机构推动位于预设电池仓位内的热失控电池通过应急出口,直接将热失控电池转运至换电站的外部。
该实施例的应急出口与预设电池仓位的设计,由于电池架靠近应急窗口设置,码垛机的伸出机构无需伸出至换电站的外部,只需码垛机的伸出机构推动电池,电池就能够从预设电池舱位的位置经应急出口滑落至换电站的外部,使得码垛机的操作简单、快速,提高热失控电池的转移效率以及提高换电站的安全性。
虽然以上描述了本发明的具体实施方式,但是本领域的技术人员应当理解,这仅是举例说明,本发明的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本发明的原理和实质的前提下,可以对这些实施方式做出多种变更或修改,但这些变更和修改均落入本发明的保护范围。
