Description

Technical Field

[0001] This utility model belongs to the field of electric energy storage technology, specifically a multi-dimensional vector fully immersed overflow energy storage pack and energy storage chamber. Background Technology

[0002] Currently, with the continuous improvement of my country's energy consumption structure, the energy storage battery industry is experiencing explosive growth, and the safety and stability of energy storage systems are attracting increasing attention. During charging and discharging, energy storage batteries generate a large amount of heat due to ohmic heat and polarization heat. If this heat cannot dissipate in time, its accumulation inside the battery can increase the rate of side reactions at the battery interface, and excessive heat accumulation may lead to thermal runaway. Therefore, efficient heat dissipation measures are a crucial consideration in energy storage battery design.

[0003] In its earlier Chinese patent application, CN 2025201760142, entitled "A Fully Immersed Energy Storage Tank Based on Partitioned Overflow," the applicant sealed the energy storage pack and created multiple partitions between the pack and the inner wall of the tank. These partitions guided the flow of the temperature-controlled medium within the tank, improving the temperature control performance of the energy storage pack. However, during operation, the tank, except for the rear overflow zone, needs to be filled with the temperature-controlled medium. The high density of this medium leads to excessive pressure on the energy storage pack at the bottom of the tank. This excessive pressure can cause the seal on the pack to fail, resulting in cross-flow of the temperature-controlled medium within the tank and reducing the effectiveness of the metered flow channel for temperature control.
