  "textContent": "A lower box body (1), a battery pack (100) and a vehicle, where the battery pack (100) includes the lower box body (1) and a battery cell (3); the lower box body (1) has an accommodating area (16), and the battery cell (3) is accommodated in the accommodating area (16); the lower box body (1) is further provided with an exhaust port (141) and an exhaust channel (142), and the exhaust port (141) is in communication with the exhaust channel (142); the exhaust port (141) is arranged in the lower box body (1) of corresponding accommodating area (16); and the lower box body (1) further includes an exhaust assembly (15), the exhaust assembly (15) is blocked at the exhaust port (141), and the exhaust assembly (15) is configured to be open when pressure in the accommodating area (16) reaches a set value, so that gas in the accommodating area (16) enters the exhaust channel (142) through the exhaust port (141). Once thermal runaway occurs in a certain battery cell (3), a large amount of high-temperature gas will be generated inside the battery cell. The high-temperature gas can penetrate the exhaust assembly (15) and enter the exhaust channel (142), and then be discharged to the outside of the battery pack (100). In this way, the probability of thermal runaway of adjacent battery cells (3) can be reduced, thereby improving safety performance of the battery pack (100).",
