Description

集卡换电电池包及其换电方法 技术领域
本发明涉及车辆换电领域，尤其涉及一种集卡换电电池包及其换电方法。
背景技术
当前，新能源汽车虽然已经进入相对成熟的发展阶段，但与传统燃油车相比，由于起步时间短，消费者对纯电动汽车三电系统在使用过程中的稳定性格外注重。尤其是其中的动力电池，更是新能源车的核心命脉。
在重型集卡的新能源换电站系统中，电池包做为能量转运单元，结构布置设计至关重要。现有的电池包多采用水冷系统的空调顶部布置，造成水冷系统的补水箱更高(补水箱与空调有一定高度差)，补水箱与空调都布局增加了电池包的整体高度，从而造成整个电池包高度比较高；另外在与车载底座交互时导向机构复杂；第三电池包大都采用的是顶部吊装，由于是顶部吊装，所以电池本身的高度不是很敏感。现有技术的这些结构都难以降低电池包的高度。
所以，当需要电池的使用方法进行改进时，例如：需要将电池包进行侧装时，电池包的高度过高就会明显影响电池包安装的精度，造成电池包与电池仓发生碰撞等等，产生安全隐患。
需要说明的是，上述背景技术部分公开的信息仅用于加强对本发明的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。

下面以附图为参考，针对本申请的实施例进行详细说明，以便本申请所属技术领域的技术人员能够容易地实施。本申请可以以多种不同形态体现，并不限定于此处说明的实施例。
在本申请的表示中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的表示意指结合该实施例或示例表示的具体特征、结构、材料或者特点包括于本申请的至少一个实施例或示例中。而且，表示的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本申请中表示的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
此外，术语“第一”、“第二”仅用于表示目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或隐含地包括至少一个该特征。在本申请的表示中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
为了明确说明本申请，省略与说明无关的器件，对于通篇说明书中相同或类似的构成要素，赋予了相同的参照符号。
在通篇说明书中，当说某器件与另一器件“连接”时，这不仅包括“直接连接”的情形，也包括在其中间把其它元件置于其间而“间接连接”的情形。另外，当说某种器件“包括”某种构成要素时，只要没有特别相反的记载，则并非将其它构成要素排除在外，而是意味着可以还包括其它构成要素。
当说某器件在另一器件“之上”时，这可以是直接在另一器件之上，但也可以在其之间伴随着其它器件。当对照地说某器件“直接”在另一器件“之上”时，其之间不伴随其它器件。
虽然在一些实例中术语第一、第二等在本发明中用来表示各种元件，但是这些元件不应当被这些术语限制。这些术语仅用来将一个元件与另一个元件进行区分。例如，第一接口及第二接口等表示。再者，如同在本发明中所使用的，单数形式“一”、“一个”和“该”旨在也包括复数形式，除非上下文中有相反的指示。应当进一步理解，术语“包含”、“包括”表明存在的特征、步骤、操作、元件、组件、项目、种类、和/或组，但不排除一个或多个其他特征、步骤、操作、元件、组件、项目、种类、和/或组的存在、出现或添加。此处使用的术语“或”和“和/或”被解释为包括性的，或意味着任一个或任何组合。因此，“A、B或C”或者“A、B和/或C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A、B和C”。仅当元件、功能、步 骤或操作的组合在某些方式下内在地互相排斥时，才会出现该定义的例外。
此处使用的专业术语只用于言及特定实施例，并非意在限定本申请。此处使用的单数形态，只要语句未明确表示出与之相反的意义，那么还包括复数形态。在说明书中使用的“包括”的意义是把特定特性、区域、整数、步骤、作业、要素及/或成份具体化，并非排除其它特性、区域、整数、步骤、作业、要素及/或成份的存在或附加。
虽然未不同地定义，但包括此处使用的技术术语及科学术语，所有术语均具有与本申请所属技术领域的技术人员一般理解的意义相同的意义。普通使用的字典中定义的术语追加解释为具有与相关技术文献和当前提示的内容相符的意义，只要未进行定义，不得过度解释为理想的或非常公式性的意义。

本发明的具体实施方式为：
参见图1至7所示，本发明的集卡换电电池包中电池包主体1包括：一电池包骨架13、一第一换电连接器23、一高压接线盒24、一高压控制盒26、一空调压缩机21、一电池组以及一水冷补水箱22。其中，X方向为集卡的长度方向、Y方向为集卡的宽度方向、Z方向为集卡的高度方向。电电池包骨架13之间设有横向或纵向的相互交错的主梁11，以便步加强电池包骨架13的承重墙度。电池包骨架13两侧，在横向的主梁11与纵向的主梁11的交叉处沿背离内部空间的方向延展出至少一电池包耳板12，后续换电机器人通过支撑电池包耳板12来搬运电池包主体1。电池包骨架13的内侧还设有若干用于与集卡中电池仓的导向支架32进行机械对位的贯通孔。并且，主梁11之间设有若干交叉斜筋14，以便进一步加强电池包骨架13的承重墙度。池包骨架13限定的内部空间分为上层和下层。电池组呈矩阵排列于电池包骨架13的上层，空调压缩机21的水冷管路联通电池组，冷媒自空调压缩机21流出后经过反重力方向的行程到达电池组中的电池包。空调压缩机21为一卧式压缩机，卧式压缩机中电机的旋转轴平行于集卡的长度方向。电池组中的同行的电池包的水冷管路形成串联管路，电池组中的异行的电池包的水冷管路形成并联管路，高压接线盒24、高压控制盒26和空调压缩机21的高度均相同。容纳高压接线盒24的第一空间区域15、容纳高压控制盒26的第二空间区域16和容纳空调压缩机21的第三空间区域17在下层中沿集卡的宽度方向(Y方向)依次排列。水冷补水箱22设置于电池组中位置最高的电池包的一侧，水冷补水箱22联通电池包和空调压缩机21。第一换电连接器23设置于第二空间区域16的底部，第一换电连接器23电连接高压控制盒26。电池包主体1中的电池包通过第一换电连接器23向集卡供电。高压控制盒26电连接高压接线盒24，高压接线盒24电连接电池组。
本发明相当于将电池包骨架13的内部空间划分为了容纳电池包的上层和提供 不同功能的下层，并且在下层中，将高压接线盒24、高压控制盒26和空调压缩机21沿集卡宽度方向(Y方向)来排列，使得高压接线盒24、高压控制盒26和空调压缩机21在集卡宽度方向(Y方向)上尽可能地重叠，从而减少电池包的侧向高度和宽度，整体缩小了电池包的侧向的投影面积。从而集卡能够使用更小的空间来设置和更换电池包，突破了现有电池包形态的固有结构，尤其能让侧装型的电动车所在更换电池的时候减少电池包与电池仓的碰撞，提高更换电池的安全性和效率。
图8是本发明的集卡换电电池包换电方法的流程图。图9至10是本发明的集卡换电电池包换电方法的实施过程示意图。如图8所示，本发明的一种集卡换电电池包的换电方法，采用上述的集卡换电电池包，包括以下步骤：
S110、换电机器人2通过支撑电池包主体1两侧的电池包耳板12，来将电池包主体1沿集卡4的宽度方向(Y方向)进入集卡4的电池仓(参见图9)。
S120、在电池包主体1到达电池仓中电池对接位上方时，放下电池包主体1，令电池包主体1与电池对接位进行机械对位和电连接。(参见图10)。其中，集卡4的电池对接位设有至少两导向支架32和第二换电连接器31，电池包主体1的电池包骨架13的定位孔垂直插入导向支架32，引导第一换电连接器23和第二换电连接器31垂直对接。
综上，本发明的集卡换电电池包及其换电方法，能够通过创新的内部布局，大大缩小电池包的整体体积，尤其是高度，从而让侧装型的电动车所在更换电池的时候减少电池包与电池仓的碰撞，提高更换电池的安全性和效率。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视 为属于本发明的保护范围。
