Disclosed are a battery protection structure, which is suitable for preventing deformation caused by physical stress at a coupling portion of a base plate and an end plate, which are stacked sequentially, and a battery module comprising the battery protection structure. The battery protection structure includes: a base plate located below a battery assembly and having a male screw member around the battery assembly; an end plate located at a side of the battery assembly on the base plate; and a reinforcing member provided below the end plate and located between a barrier of the end plate and a flange protruding from the barrier, wherein the male screw member passes through the reinforcing member and the flange, and a female screw is coupled to a male screw of the male screw member on the reinforcing member.

Battery protection structure and battery module comprising same

The present invention provides a battery compression inhibitor and a battery module comprising the same, the battery compression inhibitor being suitable for preventing at least one battery assembly from being compressed by repeated application of an external force between end plates. The battery compression inhibitor according to the present invention comprises, in order to protect a battery assembly inside a battery module: a barrier positioned on the periphery of the battery assembly and exposed from the battery assembly; and a base plate exposed from the battery assembly and from the barrier below the battery assembly and below the barrier.

Battery compression inhibitor and battery module comprising same

Provided is a battery pack including a pack case configured to form an exterior; a cell assembly accommodated in the pack case, and including a plurality of battery cells respectively including electrode leads; a pack cover configured to cover the pack case so as to package the cell assembly; and a lead connecting substrate provided between the cell assembly and the pack cover, configured to connect the electrode leads of the plurality of battery cells to one another, and including insert-molded terminals penetrating through the pack cover to be connected to an external power supply.

Battery pack and vehicle comprising the same

Disclosed is a battery connecting unit which is placed on a lower housing and protruding from an upper housing and thus is suitable for preventing water penetration from the outside of the upper housing, and a battery pack including the same. The battery connecting unit is electrically connected to a battery laminate between a lower housing and an upper housing of a battery pack and includes a plastic member configured to come into contact with the upper housing and a metal terminal inserted into the upper housing, wherein the plastic member partially surrounds the metal terminal, and wherein the metal terminal is made of a circular pillar. In addition, the battery pack includes the battery connecting unit.
