Abstract: This application relates to an exhaust system for an energy storage device, an energy storage device, and an electrical device. When thermal runaway occurs inside a battery cabinet of the energy storage device, high-temperature fumes can be expelled directionally into a corresponding exhaust assembly through an exhaust port under the action of a guide assembly, and then expelled out of a box through the exhaust assembly, thereby implementing directional exhaustion of the high-temperature fumes in the battery cabinet, avoiding explosion of the battery cabinet or secondary hazards, and improving safety performance of the energy storage device.
