在本申请的描述中，需要说明的是，除非另有说明，“多个”的含义是两个以上；术语“上”、“下”、“左”、“右”、“内”、“外”等指示的方位或位置关系仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”、“第三”等仅用于描述目的，而不能理解为指示或暗示相对重要性。“垂直”并不是严格意义上的垂直，而是在误差允许范围之内。“平行”并不是严格意义上的平行，而是在误差允许范围之内。

目前，从市场形势的发展来看，蓄电装置的应用越加广泛。蓄电装置不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，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。随着蓄电装置应用领域的不断扩大，其市场的需求量也在不断地扩增。
在一些相关技术中，蓄电装置包括至少两个电池单体，相邻两个电池单体之间设置隔板，为了对电池单体进行限位，且还要使电池单体与隔板之间形成冷却通道，隔板的一部分部位与其中一邻近的电池单体抵接，隔板的另一部分部位与另一邻近的电池单体抵接，隔板没有与电池单体抵接的部位形成冷却通道，因此，隔板一般为“弓”字形隔板。
发明人发现：“弓”字形隔板两侧的受力部位不对称，“弓”字形隔板老化后由于两侧部位受力不对称容易产生变形，造成冷却通道的形状及流通面积发生改变，使冷却效果减弱。
基于此，本申请实施例提供了一种蓄电装置，包括：沿第一方向依次排布的至少两个电池单体；以及分隔件，设于相邻两个电池单体之间；分隔件包括邻近其中一个电池单体的第一侧面，第一侧面设有至少一个第一分隔条，第一分隔条、第一侧面和电池单体之间围合形成至少一个第一通道。

相邻两个第一分隔条21之间的距离不固定，可以根据电池单体1沿第一方向X的尺寸，分隔件2沿第一方向X的尺寸，以及相邻两个电池单体1在第一方向X上的距离确定。通过优化相邻两个第一分隔条21之间的距离，能够优化电池单体1的换热面的受力分布，提高冷却效率和电池单体的循环寿命。
