The present invention refers to a battery system (100) comprising a stack comprising a plurality of battery cells (101, ..., 1012); fluid springs (30); and fluid pressure adjusting means (12,). The fluid springs (30) are positioned between first and second end plates (40a, 40b), and are configured for exerting a pressure on the battery cells. At least one of the fluid springs (30) comprises an elastic device, the elastic device having a predefined Young's modulus. The fluid pressure adjusting means (12) is connected to one or more fluid springs (30) comprising an elastic device is configured to generate an underpressure in the fluid within the connected fluid springs (30). Also, the battery system allows for avoiding or minimizing the risk of spill-over of a thermal runaway between different cells of the battery system. The present invention also refers to a method for operating the battery system.

    本发明涉及一种电池系统(100),包括:包含多个电池单元(101、……、1012)的堆叠;流体弹簧(30);和流体压力调节机构(12)。流体弹簧(30)位于第一端板(40a)和第二端板(40b)之间,并配置用于对电池单元施加压力。流体弹簧(30)中的至少一个包括弹性装置,该弹性装置具有预定的杨氏模量。流体压力调节机构(12)连接到包括弹性装置的一个或更多个流体弹簧(30),该弹性装置配置为在所连接的流体弹簧(30)内的流体中产生负压力。此外,该电池系统允许避免或最小化热失控在电池系统的不同单元之间溢出的风险。本发明还涉及用于操作该电池系统的方法。
