Battery pack with reinforcement member and pressure relief structure

A battery pack, comprising:

• a battery box body;
• a pressure relief structure, which is disposed on the battery box body;
• a first battery assembly, which comprises a plurality of first single cells disposed along a first direction, wherein the first battery assembly is disposed in the battery box body;
• a reinforcement member, which is disposed in the battery box body, and is located between the battery box body and the first battery assembly, wherein the reinforcement member is provided with a gas guiding channel, the gas guiding channel comprises a first opening, and an orthographic projection of the first opening facing a surface of the battery box body provided with the pressure relief structure coincides with at least a part of the pressure relief structure, such that a gas discharged from the first opening is in contact with the pressure relief structure,
• a second battery assembly, which comprises a plurality of second single cells disposed along the first direction, wherein the first battery assembly and the second battery assembly are disposed on the battery box body along a second direction, and the first direction is perpendicular to the second direction,
• wherein one side of the second single cell at an end portion of the second battery assembly facing the battery box body is aligned with one side of the reinforcement member facing the battery box body,
• wherein the first single cell at an end portion of the first battery assembly and the second single cell at the end portion of the second battery assembly are adapted to be electrically connected to each other through a bus bar,
• wherein the reinforcement member is provided with an avoidance space for accommodating a part of the bus bar, and the avoidance space is located above the reinforcement member.
