目前，从市场发展前景及应用趋势来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源***，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。At present, from the perspective of market development prospects and application trends, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydraulic, thermal, wind and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric vehicles, as well as military equipment and aerospace and other fields . With the continuous expansion of power battery application fields, its market demand is also constantly expanding.
由于电池自身的特性，集中存放时易出现安全隐患，如电池自燃等，故目前本领域中多采用专用的储能装置，实现对电池单体的集中存放及利用。前述专用的储能装置在使用时，需要为储能装置单独设计灭火剂，并通过管道将灭火剂引入到电池单体处，灭火剂需要单独的空间进行存放，管道也需要单独进行铺设，实际使用中施工复杂且成本较高。Due to the characteristics of the battery itself, potential safety hazards are likely to occur during centralized storage, such as spontaneous combustion of the battery. Therefore, special energy storage devices are often used in this field to realize the centralized storage and utilization of battery cells. When using the above-mentioned special energy storage device, it is necessary to design a fire extinguishing agent for the energy storage device separately, and introduce the fire extinguishing agent to the battery cell through the pipeline. The fire extinguishing agent needs to be stored in a separate space, and the pipeline also needs to be laid separately. In use, the construction is complicated and the cost is high.
本申请发明人注意到，由于解决前述问题，本领域中尝试将消防机构直接架设到储能装置的周侧支撑结构中，但是实际储能装置中往往储存有大量电池单体，消防机构设置于周侧，在出现火情时，消防介质无法喷洒到储能装置的内部深处，达不到降低电池组温度的目的，存在复燃风险。The inventors of the present application have noticed that due to solving the aforementioned problems, attempts have been made in the field to erect the fire protection mechanism directly into the peripheral support structure of the energy storage device, but the actual energy storage device often stores a large number of battery cells, and the fire protection mechanism is set in On the peripheral side, when a fire occurs, the fire-fighting medium cannot be sprayed deep inside the energy storage device, and the purpose of reducing the temperature of the battery pack cannot be achieved, and there is a risk of re-ignition.
为了缓解现有储能装置中的消防缺陷，申请人研究发现，可以通过将储能装置中的换热机构及消防机构进行整合，使换热机构中长期循环的换热液体，在出现火情时供消防机构利用，能够显著减少储能装置中的管路结构，降低设计难度及架设成本，具有普遍适用性。In order to alleviate the fire-fighting defects in the existing energy storage device, the applicant found that by integrating the heat-exchanging mechanism and the fire-fighting mechanism in the energy-storage device, the long-term circulation of the heat-exchanging liquid in the heat-exchanging mechanism can be reduced in the event of a fire It can be used by fire-fighting agencies from time to time, which can significantly reduce the pipeline structure in the energy storage device, reduce the difficulty of design and the cost of erection, and has universal applicability.
基于以上考虑，为了解决现有储能装置中的安全问题，本申请发明人经过深入研究，设计了一种储能装置。Based on the above considerations, in order to solve the safety problem in the existing energy storage device, the inventor of the present application designed an energy storage device after in-depth research.
本申请中，储能装置可以是彼此结合的利用新的可再生能量的***、电池***和现有的电力***。In this application, the energy storage device may be a system utilizing new renewable energy, a battery system, and an existing power system combined with each other.
本申请中，电池单体可以包括锂离子二次电池单体、锂离子一次 电池单体、锂硫电池单体、钠锂离子电池单体、钠离子电池单体或镁离子电池单体等，本申请实施例对此并不限定。电池单体可呈圆柱体、扁平体、长方体或其它形状等，本申请实施例对此也不限定。In this application, the battery cells may include lithium-ion secondary battery cells, lithium-ion primary battery cells, lithium-sulfur battery cells, sodium-lithium-ion battery cells, sodium-ion battery cells, or magnesium-ion battery cells, etc. The embodiment of the present application does not limit this. The battery cell can be in the form of a cylinder, a flat body, a cuboid or other shapes, which is not limited in this embodiment of the present application.
参照图1、图2，本申请实施方式中所称第一方向为x轴方向。Referring to FIG. 1 and FIG. 2 , the first direction referred to in the embodiments of the present application is the x-axis direction.
