• and a battery pack, wherein the battery pack is configured to provide electrical power to the power source, and the battery pack comprises:
• a box body, in which a cavity is disposed;
• a partition structure, disposed in the cavity and configured to partition the cavity into at least two accommodation regions, wherein the partition structure comprises a first partition piece;
• a battery row, disposed in the at least two accommodation regions, wherein the battery row comprises a plurality of batteries arranged alongside in a first direction, explosion-proof valves are disposed on a top cover of the batteries, the first partition piece is located between two batteries adjacent to each other in the first direction in the battery row, an upper surface of the first partition piece is lower than an upper surface of the top cover in a height direction, a recess is formed between the battery row and the first partition piece, a signal collection wire is accommodated in the recess, and the first direction is perpendicular to the height direction;
• and a shielding member, comprising a first shielding portion and a second shielding portion, wherein the first shielding portion is configured to overlay all the explosion-proof valves of the battery row, a passage is disposed between the first shielding portion and the upper surface of the top cover, the passage is configured to guide a fluid to flow along the first direction and is provided with a downward opening, and the second shielding portion is configured to close off a part of the opening, the part facing the recess directly;
• wherein the battery pack further comprises a box cover, the box cover is configured to fit on a top of the box body, an explosion-proof exhaust structure is disposed on at least one of two opposite side plates of the box cover, the two side plates are opposite to each other in the first direction, and the explosion-proof exhaust structure is configured to communicate with the passage and is configured to expel a fluid, which flows out of the passage, out of the battery pack;
• wherein the explosion-proof exhaust structure comprises an explosion-proof valve or a fragile portion, the fragile portion is a part of the at least one of two opposite side plates, and a strength of the fragile portion is lower than that of other parts of the at least one of two opposite side plates.
