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.
Claims10
An exhaust system for an energy storage device, wherein the energy storage device comprises a box and at least two battery cabinets disposed in the box, and an exhaust port is created on each battery cabinet, and the exhaust system comprises:
- an exhaust assembly, communicating with each of the exhaust ports sequentially, and configured to collect fumes expelled from the exhaust ports;
- and
- at least two guide assemblies, wherein each guide assembly is disposed between one of the exhaust ports and the exhaust assembly in communication with the exhaust port, and is configured to expel the fumes in the battery cabinet out of the box unidirectionally from the exhaust assembly through the exhaust port.
