BATTERY PACK AND VEHICLE

A battery pack (100) and a vehicle are provided. The battery pack (100) includes: a box cover (12), a battery row (41), a protective member (42), and a constraining component (5). A first path (PI) for guiding airflow to flow in a first direction (W) is provided between the protective member (42) and an upper surface of the battery row (41). The constraining component (5) is located between the battery row (41) and an inner wall (111a) of a cavity (111) in the first direction (W), at least a part of a top of the constraining component (5) is lower than the upper surface of the battery row (41), the constraining component (5) constrains the battery row (41), and the part of the top of the constraining component (5) lower than the upper surface of the battery row (41), the battery row (41), and the box cover (12) form a second path (P2) communicating with fluid in the first path (PI). The battery pack (100) allows smoother discharge of produced gas and better safety performance.
