Abstract: A battery pack, a safety control method therefor, and an electric apparatus are provided. The battery pack includes: a box assembly; a plurality of battery cells disposed in the box assembly, the battery cell having a housing; and a safety protection mechanism disposed in the box assembly and having a first state and a second state. When the safety protection mechanism is in the first state, the plurality of battery cells are insulated from the box assembly. The safety protection mechanism is in the second state when a preset trigger condition is met, and when the safety protection mechanism is in the second state, the housings of at least some of the battery cells are electrically connected to the box assembly.

Abstract: A battery housing includes an electrical cavity configured to accommodate battery cells. At least one battery cell includes a pressure relief mechanism configured to be actuated in response to internal pressure or temperature of the at least one battery cell reaching a threshold to relieve the internal pressure. The housing further includes a collection cavity configured to collect emissions from the at least one battery cell in response to the pressure relief mechanism being actuated, a separation component configured to separate the electrical cavity and the collection cavity, a partition structure configured to partition the collection cavity into a first cavity and a second cavity, and a flow channel baffle arranged in the second cavity and configured to form a flow channel for guiding the emissions. The partition structure is provided with an exhaust vent configured to guide the emissions in the first cavity into the second cavity.

Abstract: A battery module includes a first guard and a plurality of battery cells. The plurality of battery cells are arranged along a first direction. One end of the battery cell in a second direction is provided with a pressure relief mechanism. The second direction is perpendicular to the first direction. The pressure relief mechanism is configured to release the internal pressure of the battery cell when the internal pressure or temperature of the battery cell reaches a threshold value. The first guard includes a first guarding portion covering the end of the plurality of battery cells provided with the pressure relief mechanism. A plurality of venting ports are provided on the first guarding portion, and the venting port and the pressure relief mechanism are provided in a staggered manner in the second direction.
