Description
Technical field
The utility model relates to technical field of lithium-ion battery, relates in particular to a kind of large volume high capacity cell energy storage modular structure.
Background technology
Because advantages such as lithium ion battery have specific energy height, cell voltage height, storage life is long, volume is little, the lithium ion battery module has been widely used in motor vehicle field and energy storage field.Because the continuation of the journey mileage of electric motor car is less relatively, system's required voltage is higher, just require cell string and number increase in limited space.Be the feasibility that guarantees reliability, technology in the battery assembling process, the manageability of maintainability and system after sale aborning, the battery strings of some is also combined, and forms a module.Because it is little that the space of battery is installed in the electric motor car, just need cell in the module each other the gap and module between the gap reduce, electric motor car simultaneously needs discharging and recharging of long-time big multiplying power, make module and whole system temperature continue to raise and be difficult to distribute that the cell life-span seriously reduces and the fail safe of whole system reduces.In this field, there is not solution preferably at present.
In recent years, because energy storage neighborhood system desired volume is higher, just required monomer electricity core to be big capacity electricity core as far as possible.For the feasibility that guarantees reliability, technology in the battery assembling process, the economy of maintainability and system after sale, just need the battery strings of some and combine to form a module aborning.At present this field does not also form the module of standard, promotes in the electric power energy storage to run into disunity, bottleneck problem such as uneconomical.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of large volume high capacity cell energy storage modular structure is provided, and makes module have higher thermal diffusivity, improves the useful life of system.
The utility model for achieving the above object, by the following technical solutions: a kind of large volume high capacity cell energy storage modular structure, comprise upper support frame, lower support frame, lower house and loam cake, monomer electricity core is between described upper and lower bracing frame, described lower support frame is fixed on the lower house, the electrode of described adjacent monomer electricity core passes described upper support frame and links together by connecting copper bar, and described loam cake is fastened on the upper support frame.
Described lower house is made of base and the sidewall that is connected with the base both sides, and the downward enclosure interior of described side wall upper part is bent to form engaging lug, and described upper support frame is connected with engaging lug by bolt.
Cover on described and be provided with the through hole that is used to draw fast plug.
The outside of described sidewall is provided with handle.
The beneficial effects of the utility model are: the utility model at square battery efficiently make up, volume capacity is than big module combined structure design.Orderly being linked together after the battery strings parallel connection, safe and reliable, mounting or dismounting be row, compact easily.
