A battery pack for propulsion of an electric road, ship or aircraft vehicle, comprising a plurality of battery modules (6), each of which comprises a plurality of clustered battery cells (7) arranged side by side with each other within an accommodation space having a substantially constant size. One or more resilient blades (L) intervene at least between some of the battery cells (7) and/or between the battery cells (7) and one or more receiving supports (9) for the battery cells (7), the blades being configured in such a way that the blades occupy a relatively small space between the battery cells (7), at the same time, the battery cell (7) is freely expanded and contracted to a predetermined maximum degree in the aforementioned accommodation space due to an electrothermal change occurring during the charging and discharging cycles of the battery cell (7) and due to a structural change in the battery cell (7) caused by the continued use and/or aging of the battery cell (7). In one embodiment, according to a "thousand-level" configuration, the battery cells (7) are arranged to be oriented horizontally with their planes above the lower tray (4A). In the case of a road vehicle, the tray (4A) forms a platform of the vehicle. There is provided a stack of cells (7) separated by an aluminum sheet (AL) which impedes the propagation of heat and flames. Between the cells there is a tube (T) for a circuit of coolant, or alternatively a cooling plate (F) is provided below the cell layer (7). The unit has one side bonded to an adjacent aluminum sheet (AL) and an opposite side also bonded to the adjacent aluminum sheet or covered by a gasket of elastically deformable material. The terminals of some side-by-side units (7) are connected to each other by bars (P) held in place by clamps (15, 17), with an arrangement for example for simplifying the assembly process.

    一种用于电动道路、船舶或飞行器交通工具的推进的电池组,包括多个电池模块(6),电池模块(6)中的每个包括多个集群的电池单元(7),电池单元(7)彼此并排布置在具有基本恒定尺寸的容纳空间内。一个或多个弹性叶片(L)至少介入在所述电池单元(7)中的一些之间,和/或在电池单元(7)与用于电池单元(7)的一个或多个容纳支撑件(9)之间,叶片以如下方式被构造:占据电池单元(7)之间的相对小的空间,同时由于在电池单元(7)的充电和放电循环期间发生的电热变化并且由于由电池单元(7)的继续使用和/或老化引起的电池单元(7)中的结构变化,让电池单元(7)在前述容纳空间内自由膨胀和收缩到预定的最大程度。在一个实施例中,根据“千层面”构造,电池单元(7)布置成以其平面在下部托盘(4A)上方水平定向。在道路交通工具的情况下,托盘(4A)形成交通工具的平台。提供了由铝片(AL)分隔的单元(7)的叠加层,铝片(AL)阻碍热和火焰的传播。在单元之间存在用于冷却剂的回路的管(T),或者备选地,在单元层(7)下面提供冷却板(F)。单元具有粘合到相邻铝片(AL)的一侧和也粘合到相邻铝片或由可弹性变形材料的衬垫覆盖的相对侧。一些并排的单元(7)的端子通过由夹具(15,17)保持在适当位置的条(P)彼此连接,具有例如用于简化组装过程的布置。
