Abstract

A battery module having restrainer and method of fixing restrainer, the battery module including a pair of end plates facing each other; a restrainer coupled to the pair of end plates, the restrainer being for restraining expansion of the battery unit; and a coupling unit for coupling the end plates and the restrainer to each other, wherein the coupling unit includes a variable position coupling device configured to fix the restrainer and the end plate while varying a coupling location between the restrainer and the end plate.

Description

technical field [0001] Various embodiments relate to a battery module with a limiter and a method of securing the limiter. Background technique [0002] A battery module manufactured by connecting a plurality of batteries is an element of a large-capacity energy supply unit. The battery module can be used, for example, as a power source for electric vehicles. [0003] Battery modules typically include, for example, lithium-ion batteries. The performance of Li-ion batteries rarely degrades, even after repeated charge / discharge operations. However, when a lithium-ion battery is charged, the lithium-ion battery expands due to the movement of lithium ions. Since the battery module includes multiple lithium-ion cells, the battery module may expand by approximately 5-10% from its original size. Therefore, the battery module may be deformed. It may thus be difficult to attach and / or detach the battery module to and / or from a desired position; and the resistance of the lithium ...
