Description

Energy storage battery Pack structure Technical Field The utility model belongs to the technical field of batteries, and particularly relates to an energy storage battery Pack structure. Background With the rapid development of the fields of new energy power generation, smart grids, electric automobiles and the like, an energy storage battery system (such as a lithium ion battery, a sodium-sulfur battery and the like) becomes a core energy storage carrier due to high energy density and cycle performance. However, the temperature of the battery is increased due to heat generated by internal resistance in the charging and discharging process, if the heat cannot be dissipated in time, the problems of uneven temperature distribution, cycle life decay, thermal runaway and the like in the battery pack are caused, and the safety and the economy of the system are seriously threatened. Therefore, efficient thermal management techniques are a key element in the design of energy storage cells Pack. At present, heat dissipation schemes of energy storage batteries Pack are mainly divided into two types, namely passive natural heat dissipation and active liquid cooling heat dissipation: The natural heat dissipation of planar metal plates generally transfers the heat of the battery to the surface of a Pack through the heat conduction characteristic of a metal shell (such as aluminum alloy metal plates), and then the natural convection heat dissipation is dependent on air. The scheme has simple structure and low cost, but the heat dissipation efficiency is greatly influenced by the environmental temperature, and the requirement on the temperature uniformity under the high-power working condition is difficult to meet because of the long heat conduction path and high heat resistance of the metal plate. The liquid cooling heat dissipation is generally to embed a liquid cooling plate between the battery modules, and the heat dissipation capability is obviously better than natural heat dissipation by means of forced heat dissipation of cooling liquid circulation, but the liquid cooling heat dissipation has the defects of high system complexity (parts such as pumps, pipelines, heat exchangers and the like are needed), strict sealing requirements, high maintenance cost and the like, and particularly has poor economical efficiency for small and medium-scale energy storage scenes. Therefore, development of a novel heat dissipation technology is needed, which can solve the defects of the existing scheme in terms of temperature uniformity, adaptability and reliability while achieving both light weight and low cost. Disclosure of utility model The utility model aims to provide an energy storage battery Pack structure to solve the technical problems that an existing sheet metal heat conduction path is long, heat resistance is high, natural heat dissipation surface area is small, sheet metal heat conduction efficiency is low, overall heat dissipation is slow, and requirements for temperature uniformity, adaptability, reliability and the like under a high-power working condition are difficult to meet.
