本申请引用于2022年02月11日递交的名称为“储能系统”的第202220281281.2号中国专利申请，其通过引用被全部并入本申请。
技术领域
本申请涉及电池技术领域，特别是涉及一种储能系统。
背景技术
目前，随着社会经济的发展，由一壳体及容置于该壳体内的若干个电池模组组合形成的储能系统已被广泛地应用于电动交通工具，军事装备、航空航天设备上。
当电池模组热失控时，为防止可燃气体在壳体内聚集而发生爆炸，需对壳体内的可燃气体的浓度进行实时监控，并在壳体内的可燃气体的浓度达到设定浓度时及时将可燃气体排出至壳体外。
然而，在传统的储能系统中，在电池模组热失控时，壳体内的可燃气体的排出效率较低，进而导致储能系统仍存在爆炸的风险。
发明内容
基于此，有必要针对可燃气体的排出效率较低的上述问题，提供一种能够提升可燃气体的排出效率的储能系统。
一种储能系统，包括：
壳体，其上开设有进风口及出风口；
检测件，配接于所述壳体，并用于检测所述壳体内可燃气体的浓度；以及
进风机及出风机，均配接于所述壳体；所述进风机用于驱动外部气流经所述进风口流入所述壳体内，所述出风机用于驱动所述壳体内的气流经所述出风口流出至外部；
其中，所述进风机及所述出风机均被配置为在所述可燃气体的浓度等于或大于设定范围的最小值时启动。
上述储能系统，在储能系统供能的过程中，检测件实时检测壳体内可燃气体的浓度，且当可燃气体的浓度等于或大于设定范围的最小值时，进风机及出风机均启动，进风机可驱动外部气流流入至壳体内，出风机可引导壳体内的气流及可燃气体排出至外部。由于进风机及出风机的设置，可加速壳体内可燃气体的排出，从而使得可燃气体具有较高的排出效率。
在其中一实施例中，所述储能系统包括控制器，所述控制器被配置为在所述可燃气 体的浓度等于或大于所述设定范围的最小值时控制所述进风机及所述出风机启动。
在该实施例中，由于控制器的设置，整个储能系统的工作过程无需人为监控，从而有利于实现储能系统防爆的自动化。
在其中一实施例中，所述储能系统包括灭火件，其配接于所述壳体并与所述控制器电连接；
其中，所述控制器被配置为在所述可燃气体的浓度大于所述设定范围的最大值时控制所述灭火件对所述壳体内执行灭火操作。
当壳体内的电池模组发生热失控时，壳体内的可燃气体的浓度有可能大于设定范围的最大值，如此，将容易导致电池模组爆炸并燃烧。而通过设置控制器控制灭火件对壳体内进行灭火操作，可有效且及时地控制壳体内的火势并降低壳体内的温度，从而可防止火势蔓延而造成严重的安全事故。
在其中一实施例中，所述壳体还包括设置于所述进风口和/或所述出风口处的启闭门，所述启闭门被配置为在所述可燃气体的浓度等于或大于所述设定范围的最小值时打开对应的所述进风口和/或所述出风口。
储能系统正常供电时，所有的启闭门均关闭，所有的启闭门共同阻止外界水汽及灰尘等进入至壳体内，以避免水汽及灰尘影响电池模组的工作产生。当壳体内可燃气体的浓度等于或大于设定范围的最小值时，所有的启闭门均打开，以保证壳体内部能够与外部进行气流交换。由此可见，启闭门根据壳体内可燃气体的浓度适时开启或关闭，保证了储能系统能够正常供电且能够与外部之间进行气流交换。
在其中一实施例中，所述储能系统还包括密封件，所述密封件设置于具有所述启闭门的所述进风口和/或所述出风口的外周，并在所述可燃气体的浓度小于所述设定范围的最小值时，密封于当前所在的所述进风口和/或所述出风口上所述启闭门与所述壳体之间。
储能系统正常供电时，壳体内可燃气体的浓度小于设定范围的最小值，覆盖于进风口处的启闭门与壳体之间和/或覆盖于出风口处的启闭门与壳体之间通过密封件密封，以防止外部的水汽及灰尘进入。当壳体内可燃气体的浓度等于或大于设定范围的最大值时，所有的启闭门均打开，密封件的密封作用失效。
在其中一实施例中，所述壳体的表面开设有插槽，所述插槽布设于所述密封件的外周；所述启闭门包括门主体及凸出形成于所述门主体一侧的翻边，所述翻边在所述启闭门相对当前所在的所述进风口或所述出风口关闭时，卡嵌于对应的所述插槽内。
翻边与插槽的配合，能够进一步提升该翻边所在的启闭门与壳体之间配合的紧密度，从而使得与该启闭门对应的密封件能够可靠地夹紧于该启闭门的门主体与壳体之间。
在其中一实施例中，所述插槽的深度大于与之对应的所述翻边的宽度。
因此，当每个启闭门关闭对应的进风口或出风口时，该启闭门中的翻边能够完全插 入至对应的插槽内。如此，翻边与插槽之间的配合更牢靠，从而可防止翻边退出对应的插槽。
在其中一实施例中，每个所述启闭门朝向所述进风口或所述出风口的表面铺设有保温层。
保温层的设置，使得壳体内的热量由每个启闭门扩散至外部的速率变得极慢，因此，壳体内可维持较为适宜的温度以使得电池模组能够正常供电。
在其中一实施例中，还包括磁吸件，所述启闭门被配置为在与其对应的所述磁吸件的作用下吸附于所述壳体上。
因此，每个启闭门能够稳定地关闭进风口或者出风口。
在其中一实施例中，所述壳体包括壳主体、分隔板、出风管及阻断门，所述分隔板将所述壳主体内分隔形成电气仓及电池仓；
所述分隔板上开设有连通口，所述出风管依次贯穿所述连通口、所述电气仓及所述出风口，并与所述电池仓及外部连通，所述阻断门配接于所述分隔板并用于启闭所述连通口。
其中，壳主体具有容置仓，分隔板位于容置仓内，并将容置仓分隔形成电气仓及电池仓。检测件用于检测电池仓内可燃气体的浓度，控制器用于阻断门的启闭。当电池仓内可燃气体的浓度小于设定范围的最小值，控制器控制阻断门关闭，电气仓及电池仓相互隔离，电池模组位于电池仓内供电，电气元件位于电气仓工作，且电池模组与电气元件之间互不影响。当电池仓内可燃气体的浓度等于或大于设定范围的最小值时，控制器控制阻断门打开，以使得电池仓内的可燃气体浓度可经出风管及出风口排出至外部。

请参阅图1，目前，从市场形势的发展来看，能够储蓄并供应电能的储能系统1的应用越加广泛。该储能系统1不仅被应用于水力、火力、风力和太阳能电站等储能装置，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着储能系统1应用领域的不断扩大，其市场的需求量也在不断地扩增。
请一并参阅图2，储能系统1通常包括壳体10及若干个电池模组70，所有电池模组70设置于壳体10内，并用于储蓄及供应电能。每个电池模组70包括电池单体71和箱体72，电池单体71容纳于箱体72内。其中，箱体72用于为电池单体71提供容纳空间，箱体72可以采用多种结构。
在一些实施例中，箱体72可以包括第一部分721和第二部分722，第一部分721与第二部分722相互盖合，第一部分721和第二部分722共同限定出用于容纳电池单体71的容纳空间。第二部分722可以为一端开口的空心结构，第一部分721可以为板状结构，第一部分721盖合于第二部分722的开口侧，以使第一部分721与第二部分722共同限定出容纳空间；第一部分721和第二部分722也可以是均为一侧开口的空心结构，第一部分721的开口侧盖合于第二部分722的开口侧。当然，第一部分721和第二部分722形成的箱体72可以是多种形状，比如，圆柱体、长方体等。
随着单个或者多个电池模组70长时间作业，工作的电池模组70容易发生热失控。热失控时，可燃气体(H2、CO、CH4等等)在壳体10内集聚而爆炸，进而造成严重的安全事故。由此可见，如何对储能系统1进行防爆设计显得尤为重要。
据悉，传统的防爆方式为在壳体10内设置排风扇及采集件，采集件及排风扇均与外部终端电连接。采集件采集壳体10内的可燃气体的浓度并反馈至外部终端，且当采集件采集的浓度等于或大于设定阈值时，外部终端可控制排风扇工作，以驱动外部气流经壳体10内部流出。这样能够加强外部与壳体10内部的空气对流，从而有助于降低壳体10内部可燃气体的浓度。
本申请人注意到，当电池模组70发生热失控时，采用传统的通过排风扇及采集件排出壳体10内的可燃气体的方式时，单个排风扇的导流效果较弱，如此，导致可燃气体的排出效率较低，储能系统1仍存在爆炸的风险。
请一并参阅图3、图4及图5，为降低储能系统1的防爆风险，经申请人仔细研究发 现，可以在壳体10上配接设置一个进风机20及出风机30，并在壳体10上设置检测件，检测件实时检测壳体10内的可燃气体的浓度，当可燃气体的浓度等于或大于设定范围的最小值时启动，进风机20用于驱动外部气流流入至壳体10内，出风机30用于驱动壳体10内的气流流出至外部。在进风机20及出风机30的协同作用下，外部气流能够高效被驱动并流入至壳体10内，而壳体10内部的气流亦能够快速流出至外部，因此，整个储能系统1的防爆风险急剧下降。
在对储能系统1的安全性需求日益增加的背景下，本申请中的储能系统1能够在壳体10内的可燃气体超标时，及时且高效地排出壳体10内的可燃气体，这在电池领域具有极为重要的意义。
其中，设定范围可以根据需求进行设置，仅需保证的是，当可燃气体的浓度小于设定范围的最小值时，储能系统1并未发生热失控即可。
本申请中提供的储能系统1包括若干个电池模组70、壳体10、检测件、进风机20及出风机30，壳体10上开设有进风口112及出风口113，所有电池模组70设于壳体10内，检测件、进风机20及出风机30均配接于壳体10上。检测件用于检测壳体10内可燃气体的浓度，进风机20用于驱动外部气流经进风口112流入壳体10内，出风机30用于驱动壳体10内的气流经出风口113流出至外部。其中，进风机20及出风机30均被配置为在可燃气体的浓度等于或大于设定范围的最小值时启动。
在储能系统1供能的过程中，检测件实时检测壳体10内可燃气体的浓度，且当可燃气体的浓度等于或大于设定范围的最小值时，进风机20及出风机30均启动，进风机20可驱动外部气流流入至壳体10内，出风机30可引导壳体10内的气流及可燃气体排出至外部。由于进风机20及出风机30的设置，可加速壳体10内可燃气体的排出，从而使得可燃气体具有较高的排出效率。
在一实施例中，储能系统1还包括控制器40，控制器40被配置为在可燃气体的浓度等于或大于设定范围的最小值时控制进风机20及出风机30启动。其中，控制器40与检测件、进风机20及出风机30均电连接，检测件将检测的可燃气体的浓度实时反馈至控制器40，且当检测件反馈的可燃气体的浓度等于或大于设定范围的最小值时，控制器40控制进风机20及出风机30启动。
因此，外部气流可经进风口112流入至壳体10内，并带动壳体10内的可燃气体流出至外部。如此，壳体10内的可燃气体的浓度降低，故可防止可燃气体在壳体10内积聚而爆炸。此外，在该过程中，壳体10内的热量也可被带走，故有助于防止壳体10内热量聚集而发生热失控。在该实施例中，由于控制器40的设置，整个储能系统1的工作过程无需人为监控，从而有利于实现储能系统1防爆的自动化。
当然，进风机20及出风机30的控制方式不限于上述一种。在其他一些实施例中， 也可以在壳体10上设置显示屏及控制按键，显示屏与检测件电连接，控制按键与进风机20及出风机30均电连接。检测件将检测的可燃气体于显示屏上显示，当可燃气体的浓度等于或大于设定范围的最小值时，用户按压控制按键，则进风机20及出风机30均启动。
在一些实施例中，储能系统1包括灭火件，其配接于壳体10并与控制器40电连接。其中，控制器40被配置为在可燃气体的浓度大于设定范围的最大值时控制灭火件对壳体10内执行灭火操作。
在一些实施例中，灭火件可以为喷水器、干粉灭火器、泡沫灭火器等等。
当壳体10内的电池模组70发生热失控时，壳体10内的可燃气体的浓度有可能大于设定范围的最大值，如此，将容易导致电池模组70爆炸并燃烧。而通过设置控制器40控制灭火件对壳体10内进行灭火操作，可有效且及时地控制壳体10内的火势并降低壳体10内的温度，从而可防止火势蔓延而造成严重的安全事故。
在一实施中，壳体10还包括设置于进风口112和/或出风口113处的启闭门12，启闭门12被配置为在可燃气体的浓度等于或大于设定范围的最小值时打开对应的进风口112和/或出风口113。
储能系统1正常供电时，所有的启闭门12均关闭，所有的启闭门12共同阻止外界水汽及灰尘等进入至壳体10内，以避免水汽及灰尘影响电池模组70的工作产生。当壳体10内可燃气体的浓度等于或大于设定范围的最小值时，所有的启闭门12均打开，以保证壳体10内部能够与外部进行气流交换。由此可见，启闭门12根据壳体10内可燃气体的浓度适时开启或关闭，保证了储能系统1能够正常供电且能够与外部之间进行气流交换。
在一些实施例中，启闭门12可以为一个，且启闭门12用于启闭进风口112或者出风口113。
在一些实施例中，启闭门12为两个，两个启闭门12分别设置于进风口112及出风口113处。
储能系统1正常供电时，所有的启闭门12均关闭，壳体10内形成一个封闭的容纳电池模组70的空间，以便于将外界水汽及灰尘阻挡于壳体10外。
请再次参阅图5，并同时一并参阅图6及图7，在一些实施例中，储能系统1还包括密封件50，密封件50设置于具有启闭门12的进风口112和/或出风口113的外周，并在可燃气体的浓度小于设定范围的最小值时，密封于当前所在的进风口112和/或出风口113上启闭门12与壳体10之间。
储能系统1正常供电时，壳体10内可燃气体的浓度小于设定范围的最小值，覆盖于进风口112处的启闭门12与壳体10之间和/或覆盖于出风口113处的启闭门12与壳体10之间通过密封件50密封，以防止外部的水汽及灰尘进入。当壳体10内可燃气体的浓度等于或大于设定范围的最大值时，所有的启闭门12均打开，密封件50的密封作用失效。
在一些实施例中，若仅进风口112或出风口113处设有启闭门12，则密封件50为一个并围绕设有启闭门12的进风口112或者出风口113的周向设置。
在一些实施例中，进风口112及出风口113处均设置有启闭门12，且密封件50为两个并与两个启闭门12一一对应，其中一个围绕进风口112的周向设置，另一个围绕出风口113的周向设置。
当壳体10内可燃气体的浓度小于设定范围的最小值时，两个启闭门12分别关闭进风口112及出风口113，且每个密封件50均密封设置于对应的启闭门12与壳体10之间，如此，水汽及灰尘能够被完全隔离于壳体10外部。
在一些实施例中，壳体10的表面开设有插槽114，插槽114布设于密封件50的外周，并沿密封件50的外周延伸。启闭门12包括门主体121及凸出形成于门主体121一侧的翻边122，翻边122在启闭门12相对当前所在的进风口112或出风口113关闭时，卡嵌于对应的插槽114内。
在一些实施例中，每个密封件50的外周均布设有插槽114，每个密封件50对应的启闭门12上均设置有翻边122。
翻边122与插槽114的配合，能够进一步提升该翻边122所在的启闭门12与壳体10之间配合的紧密度，从而使得与该启闭门12对应的密封件50能够可靠地夹紧于该启闭门12的门主体121与壳体10之间。
值得一提的是，为降低翻边122从插槽114内脱离的可能性，当翻边122插入对应的插槽114内时，需保证翻边122的至少一侧能够与插槽114的槽壁贴合，以使得翻边122与插槽114的槽壁之间具有较大的接触面积。
在一些实施例中，插槽114的深度大于与之对应的翻边122的宽度。因此，当每个启闭门12关闭对应的进风口112或出风口113时，该启闭门12中的翻边122能够完全插入至对应的插槽114内。如此，翻边122与插槽114之间的配合更牢靠，从而可防止翻边122退出对应的插槽114。
在一实施例中，插槽114的径向宽度还大于与之对应的翻边122的厚度。
其中，每个翻边122具有沿其厚度方向相对设置的第一侧面及第二侧面，插槽114具有沿其径向设置的第一槽壁及第二槽壁，第一侧面朝向第一槽壁设置，第二侧面朝向第二槽壁设置。当与每个插槽114对应的翻边122插入至对应的插槽114内后，翻边122的第一侧面能够与第一槽壁贴合，且第二侧面与第二侧壁间隔设置。在该种实施例下，当遇上下雨天气时，雨水可以在第二侧面与第二槽壁之间的间隙的引导下流出至外部，以防止雨水在插槽114内聚集而渗透至壳体10内。
在一实施例中，储能系统1还包括磁吸件60，当壳体10内的可燃气体的浓度小于设定范围的最小值时，启闭门12被配置为在与其对应的磁吸件60的作用下吸附于壳体10 上，从而使得每个启闭门12能够稳定地关闭进风口112或者出风口113。
在一些实施例中，可以所有启闭门12中的部分能够在各自对应的磁吸件60的作用下吸附于壳体10上。在一些实施例中，每个启闭门12均具有对应的磁吸件60，每个启闭门12均能够在对应的磁吸件60的作用下吸附于壳体10上。
在一实施例中，每个启闭门12均为金属构件，每个启闭门12对应多个磁吸件60，并在对应的所有磁吸件60的作用下吸附于壳体10上。其中，与每个启闭门12对应的密封件50上开设有多个缺口51，与同一个启闭门12对应的所有磁吸件60及所有缺口51一一对应，每个慈吸件均配接于壳体10上，并通过对应的缺口51吸附对应的启闭门12。
在一实施例中，每个启闭门12朝向进风口112或出风口113的表面铺设有保温层123。保温层123的设置，使得壳体10内的热量由每个启闭门12扩散至外部的速率变得极慢，因此，壳体10内可维持较为适宜的温度以使得电池模组70能够正常供电。
请再次参阅图1、图3及图4，在一实施例中，壳体10包括壳主体11、分隔板13、出风管14及阻断门15，分隔板13将壳主体11内分隔形成电气仓115及电池仓116。电池仓116用于放置电池模组70，电气仓115用于放置除电池模组70外的电气元件，例如控制器40，灭火件等等。分隔板13上开设有连通口131，出风管14依次贯穿连通口131、电气仓115及出风口113，并与电池仓116及外部连通，阻断门15配接于分隔板13并用于启闭连通口131。
其中，壳主体11具有容置仓111，分隔板13位于容置仓111内，并将容置仓111分隔形成电气仓115及电池仓116。检测件用于检测电池仓116内可燃气体的浓度，控制器40用于阻断门15的启闭。当电池仓116内可燃气体的浓度小于设定范围的最小值，控制器40控制阻断门15关闭，电气仓115及电池仓116相互隔离，电池模组70位于电池仓116内供电，电气元件位于电气仓115工作，且电池模组70与电气元件之间互不影响。当电池仓116内可燃气体的浓度等于或大于设定范围的最小值时，控制器40控制阻断门15打开，以使得电池仓116内的可燃气体浓度可经出风管14及出风口113排出至外部。
其中，壳主体11为中空结构，且可以由顶板、底板、以及连接于顶板与顶板之间的侧板围合形成。或者，壳主体11还可以由框体117及包覆于框体117外的包覆层围合形成。
上述储能系统1，在储能系统1供能的过程中，检测件实时检测壳体10内可燃气体的浓度，且当可燃气体的浓度等于或大于设定范围的最小值时，进风机20及出风机30均启动，进风机20可驱动外部气流流入至壳体10内，出风机30可引导壳体10内的气流及可燃气体排出至外部。由于进风机20及出风机30的设置，可加速壳体10内可燃气体的排出，从而使得可燃气体具有较高的排出效率。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施 例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这都属于本申请的保护范围。
