Battery heat dissipation structure, battery cluster heat dissipation structure, heat dissipation system and heat dissipation method

Abstract

The invention belongs to the technical field of heat dissipation of energy storage systems, and discloses a battery heat dissipation structure, a battery cluster heat dissipation structure, a heat dissipation system and a heat dissipation method. The battery heat dissipation structure comprises an air inlet formed in one side wall of a battery module and an air outlet formed in the other side wall of the battery module, wherein one-way valves are arranged at the air inlet and the air outlet correspondingly, an exhaust pipeline is arranged on one side of the battery module, the air outlet is communicated with the exhaust pipeline, and a fan is arranged at the top of the exhaust pipeline. According to the invention, directional air flow of the module is realized, large-scale air flow in an area is avoided, the heat dissipation efficiency is improved, normal heat dissipation during battery operation is not influenced, and the problem that flue gas of battery thermal runaway is diffused to other connected modules is avoided.

Problems solved by technology

The disadvantage of this method is that the air is always circulating in the area. When the battery is in normal operation, this method can meet the needs of operation, but when the battery in the module is thermally runaway, this method is useless because: First of all, the air conditioner is installed in the area. When the battery thermal runaway is abnormal, the system will automatically cut off the power, the air conditioner will stop running, and the high-temperature smoke from the battery thermal runaway will quickly fill the inside and outside of the battery module; The high-temperature flue gas from thermal runaway will easily spread from one module to other modules, triggering a chain reaction
