具体实施方式
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
随着现代工业的发展，全球能源危机和大气污染问题日益突出，传统的燃料能源正在一天天减少，对环境造成的危害日益突出，全世界都把目光投向了可再生能源，希望可再生能源能够改变人类的能源结构，维持长远的可持续发展，动力电池的应用越加广泛。电池不仅被应用于水力、火力、风力 和太阳能电站等储能电源系统，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众多领域。随着电池应用领域的不断扩大，其市场需求量也在不断地扩增。
为便于根据实际需求灵活调节电池包数量，模块化堆叠式电池箱成为常见供电方案，模块化堆叠式电池箱通常包括主控箱体和多个电池箱体，主控箱体与多个电池箱体堆叠并通过销钉等连接件实现可拆卸固定连接，可根据需求灵活增减电池箱体的数量。
然而，在相关的模块化堆叠式电池箱中，箱体之间通过连接器及定位销相互连接，连接器及定位销结构均为外凸结构，导致电池箱整体外形尺寸较大，运输成本较高；并且，箱体一般为钣金加工件，加工误差容易导致两电池箱在堆叠后，电池箱的外观面不在同一平面，影响电池箱的整体美观性；此外，电池箱的外接线接口在位于顶部的主控箱体的侧面，出线方式为上出线，在系统需求为下出线时，线缆则需外置，进一步影响电池箱的整体美观性及安全性。
为解决上述技术问题，本公开实施方式提供一种电池箱，如图1至图3所示，电池箱包括底座组件、主控箱组件、至少一个电池箱组件和多对连接板400，多个电池箱组件沿高度方向堆叠设置在底座组件与主控箱组件之间，底座组件包括底座箱体200，如图4至图5所示，主控箱组件包括主控箱体300和设置在主控箱体300中的主控装置20，如图8至图9所示，电池箱组件包括电池箱体100和设置在电池箱体100中的电池装置10，电池箱体100的顶部具有第一维护开口101，电池箱体100及主控箱体300的底部均具有走线通孔30，主控装置20与电池装置10之间通过穿过走线通孔30的线缆连接；底座箱体200与电池箱体100、电池箱体100与主控箱体300以及相邻的电池箱体100之间均通过成对的连接板400固定连接，每对连接板400均对称设置在对应的组件沿第一水平方向的两侧。
本公开实施方式提供的电池箱包括底座组件、主控箱组件和堆叠在二者之间的至少一个电池箱组件，且相邻组件的箱体之间通过了两侧的连接板400固定连接，在实际使用中可根据需求拆下连接板400并改变堆叠的电池箱组件的数量，灵活调节电池箱的输出功率。并且，底座箱体200与电池箱体100、电池箱体100与主控箱体300以及相邻的电池箱体100之间均通过成对的连接板400固定连接，连接板400贴附在各个箱体的两侧，能够有效减小电池箱整体尺寸，提高电池箱结构的紧凑性，降低电池箱的运输成本，且连接板400能够保证其所贴附的上下两箱体表面相互平齐，进而保证多个箱体的外表面共面，提高电池箱整体的美观性。
此外，电池箱体100的顶部具有第一维护开口101，电池箱体100及主控箱体300的底部均具有走线通孔30，主控装置20与电池装置10之间通过穿过走线通孔30的线缆连接，从而无论电池箱采用上出线还是下出现的出线方式，线缆均可经由多个走线通孔30由电池箱的内部连接至外接线接口，避免线缆外置，进而提高了电池箱的整体美观性及安全性。
具体来说，底座箱体200与电池箱体100之间通过成对的连接板400固定连接，则该成对的连接板400在第一水平方向上对称设置在底座箱体200与电池箱体100的两侧。电池箱体100与主控箱体300之间通过成对的连接板400固定连接，则该成对的连接板400在第一水平方向上对称设置在电池箱体100与主控箱体300的两侧。相邻的电池箱体100之间通过成对的连接板400固定连接，则该成对的连接板400在第一水平方向上对称设置在相邻的电池箱体100的两侧。
作为本公开一实施方式，如图4至图5所示，电池装置10包括第一安装板11、电池模组12和电池管理从控单元13，第一安装板11固定设置在电池箱体100中，电池模组12和电池管理从控单元13均固定设置在第一安装板11上。
也就是说，第一安装板11设置在电池箱体100中，并与电池箱体100固定，电池模组12和电池管理从控单元13均设置在第一安装板11上，并与第一安装板11固定，从而使电池模组12和电池管理从控单元13均通过第一安装板11与电池箱体100固定。
作为本公开一实施方式，如图8至图9所示，主控装置20包括第二安装板21、动力控制模块22和电池管理主控单元23，第二安装板21固定设置在主控箱体300中，动力控制模块22和电池管理主控单元23均固定设置在第二安装板21上。
也就是说，第二安装板21设置在主控箱体300中，并与主控箱体300固定，动力控制模块22和电池管理主控单元23均设置在第二安装板21上，并与第二安装板21固定，从而使动力控制模块22和电池管理主控单元23均通过第二安装板21与电池箱体100固定。
为保证电池箱的密封性及防水性能，作为本公开一实施方式，如图4至图5所示，电池箱体100的顶部设置有环绕第一维护开口101的第一密封条140，第一密封条140密封电池箱体100的顶部与其上方的箱体底部之间的间隙。
例如，一个电池箱体100上堆叠的为另一个电池箱体100，则位于下方的电池箱体100顶部设置的第一密封条140用于对位于下方的电池箱体100的顶部与位于上方的电池箱体100的底部之间的间隙进行密封。例如，一个电池箱体100上堆叠的为主控箱体300，则位于下方的电池箱体100顶部设置的第一密封条140用于对位于下方的电池箱体100的顶部与位于上方的主控箱体300的底部之间的间隙进行密封。
如图6至图7所示，底座箱体200的顶部具有第二维护开口201，底座箱体200的顶部设置有环绕第二维护开口201的第二密封条240，第二密封条240密封底座箱体200的顶部与其上方的电池箱体100底部之间的间隙。
在相关技术方案中，箱体之间连接的连接器部分需单独做防水结构，结构较为复杂，而在本公开实施方式中，箱体之间仅通过走线通孔30及维护开口(例如，第一维护开口101和第二维护开口201)对接连通，从而仅对维护开口进行密封条密封，即可保证整个电池箱的密封性及防水性能，进一步保证电池箱的安全性。
为进一步保证电池箱各个箱体之间的对位精确性，以保证电池箱的结构稳定性及美观性，作为本公开一实施方式，如图4至图5所示，电池箱体100的顶部具有一对沿第一水平方向延伸的第一对位部121，且两个第一对位部121分别位于第一维护开口101沿第二水平方向的两侧，第二水平方向与第一水平方向相交，电池箱体100的底部具有一对沿第一水平方向延伸的第二对位部122；如图6至图7所示，底座箱体200的顶部具有一对沿第一水平方向延伸的第三对位部221，且两个第三对位部221分别位于第二维护开口201沿第二水平方向的两侧；如图8至图9所示，主控箱体300的底部具有一对沿第一水平方向延伸的第四对位部321；第一对位部121位于对应的电池箱体100的两个第二对位部122之间或对应的主控箱体300的两个第四对位部321之间；第三对位部221位于对应的电池箱体100的两个第二对位部122之间。
在本公开一实施方式中，电池箱体100顶部的两个第一对位部121插入其上方对应的两个第二对位部122之间或两个第四对位部321之间，底座箱体200顶部的两个第三对位部221插入其上方对应的两个第二对位部122之间，从而利用对位部之间的卡合限位保证多个箱体之间沿第二水平方向的对位精确性，进而保证电池箱的结构稳定性及美观性。
例如，一个电池箱体100上堆叠的为另一个电池箱体100，则位于下方的电池箱体100顶部的两个第一对位部121插入位于上方的电池箱体100底部的两个第二对位部122之间。例如，一个电池箱体100上堆叠的为主控箱 体300，则位于下方的电池箱体100顶部的两个第一对位部121插入位于上方的主控箱体300底部的两个第四对位部321之间。
作为本公开一实施方式，每对第一对位部121之间的间隔距离与两个第三对位部221之间的间隔距离一致，每对第二对位部122之间的间隔距离与两个第四对位部321之间的间隔距离一致，从而统一不同箱体顶部及底部的对位部的形状规格，进而提高配置电池箱中箱体数量及种类的便捷性。
作为本公开一实施方式，如图4至图5所示，电池箱体100包括第一底板110、一对第一侧板120和一对第一端板130，两个第一侧板120连接在第一底板110沿第二水平方向的两侧，且第一底板110与第一侧板120形成为一体，两个第一端板130固定连接在第一底板110沿第一水平方向的两侧，第一侧板120与第一端板130环绕形成第一维护开口101；如图6至图7所示，底座箱体200包括第二底板210、一对第二侧板220和一对第二端板230，两个第二侧板220连接在第二底板210沿第二水平方向的两侧，且第二底板210与第二侧板220形成为一体，两个第二端板230固定连接在第二底板210沿第一水平方向的两侧，第二侧板220与第二端板230环绕形成第二维护开口201。
作为本公开一实施方式，第一底板110与第一侧板120为一体成型的铝挤型材，第二底板210与第二侧板220为一体成型的铝挤型材。
为便于搬运电池箱体100，作为本公开一实施方式，如图4至图5所示，第一端板130部分向电池箱体100内部凹陷形成第一把手槽131。
为进一步便于搬运电池箱体100，作为本公开一实施方式，电池箱体100的成对的两个第一端板130均形成有第一把手槽131。
为进一步保证电池箱各个箱体之间的对位精确性，以保证电池箱的结构稳定性及美观性，作为本公开一实施方式，如图4至图5所示，第一底板110的底部形成有一对沿第一水平方向延伸的第一对位槽111，第一对位部 121和第三对位部221均一一对应地容纳于对应的第一对位槽111中。
例如，一个电池箱体100堆叠在另一个电池箱体100上，则位于下方的电池箱体100顶部的两个第一对位部121一一对应地容纳于位于上方的电池箱体100底部的两个第一对位槽111中。例如，一个电池箱体100堆叠在底座箱体200上，则位于下方的底座箱体200顶部的两个第三对位部221一一对应地容纳于位于上方的电池箱体100底部的两个第一对位槽111中。
作为本公开一实施方式，如图5所示，第一对位槽111的侧壁与第二对位部122的侧面相接。
也就是说，第一对位槽111的一侧壁作为第二对位部122的一侧面，第一对位槽111和第二对位部122是连续形成的，中间不存在间隔结构。
作为本公开一实施方式，如图8至图9所示，主控箱体300包括顶盖340、第三底板310、一对第三侧板320和一对第三端板330，两个第三侧板320连接在第三底板310沿第二水平方向的两侧，且第三底板310与第三侧板320形成为一体，两个第三端板330固定连接在第三底板310沿第一水平方向的两侧，第三侧板320与第三端板330环绕形成第三维护开口301，顶盖340密封第三维护开口301。
作为本公开一实施方式，第三底板310与第三侧板320为一体成型的铝挤型材。
为便于搬运主控箱体300，作为本公开一实施方式，如图9所示，第三端板330部分向主控箱体300内部凹陷形成第二把手槽331。
为进一步便于搬运主控箱体300，作为本公开一实施方式，主控箱体300的成对的两个第三端板330均形成有第二把手槽331。
作为本公开一实施方式，如图4、图8所示，走线通孔30沿第二水平方向延伸，从而在不增加电池箱第一水平方向尺寸(宽度)的同时，保证走线通孔30的走线空间。
作为本公开一实施方式，如图4、图8所示，走线通孔30沿第二水平方向的两侧边缘为圆弧形边缘，即，走线通孔30为腰型通孔，从而避免走线通孔30的内缘上具有尖锐结构划伤线缆，进一步保证电池箱的安全性。
