Background Art
[4]
In the course of using the battery, the temperature is too high or too low will affect the working performance of the battery, in order to ensure that the battery of the work performance, often heat-exchanging structure to the battery for heat exchange, such as by liquid-cooling mode to carry out heat exchange. In the prior art, in the heat exchanger when the battery, is generally in the heat exchange structure is arranged in the surface of a single battery, then the battery with the surface of the heat exchange between the heat exchange structure to realize the temperature of the battery management.
[5]
However, with the rapid development of new energy industry, in the automobile industry as a whole to the comprehensive performance of the on-vehicle battery higher demands, the energy density of the battery is getting higher and higher, the capacity of the battery is also rising, therefore monomer battery is also growing, the existing battery and the thermal management mode has been far cannot satisfy the demand.

Content of the utility model
[7]
In order to at least overcome the above deficiencies in the prior art, one of the purposes of the present application is to provide a single battery, the battery including the protection of the shell, is located in the protective shell of the battery and the battery body by formed by the through hole of the main body of the battery, the battery body by winding to form the winding structure, the battery through hole are used for the monomer battery temperature management;
[8]
The monomer battery also includes positive and negative ear, the positive electrode negative electrode tab on the main body is arranged in the battery.
[9]
Optionally, the monomer cell also includes temperature setting of the heat pipe, the heat pipe temperature setting is set in the battery in the through hole, the heat management panel is applied to the single battery temperature management.
[10]
Optionally, the temperature setting of the heat pipe is provided with a heat exchange medium flow path, the two ends of the heat exchanging medium flow path for the liquid inlet and liquid outlet respectively, in the heat exchanging medium flow passage is filled with the heat exchange medium, said monomer the battery through the heat pipe temperature setting and said heat exchanging medium to carry out heat exchange in order to realize the monomer the temperature of the battery management.
[11]
Alternatively, the heat exchanging medium flow passage passes through the heat pipe relative to the end face of the temperature setting of the end face of the 1st and 2nd, the liquid inlet port is located on the end of the 1st, the liquid outlet is located on the end of the 2nd, the 1st gear is arranged on the inlet pipeline interface, the 2nd set on the end face of the liquid outlet pipeline interface, said heat exchanging medium flow passage through the port and the liquid inlet pipe communicated with, said heat exchanging medium flow passage through said liquid outlet and the liquid outlet pipe communicated with.
[12]
Alternatively, the heat exchanging medium flow passage with a plurality of, a plurality of said heat exchanging medium flow passage direction are parallel to each other, each of the heat exchanging medium flow passage with the liquid inlet and the liquid inlet pipe communicated with, each of the heat exchanging medium flow passage with the outlet are communicated with the liquid outlet pipe interface.
[13]
Optionally, the monomer cell also includes a thermally conductive material to form a protective layer, the protective layer is located on the battery to energy consumption corresponding to the through hole on the surface of the battery main body.
[14]
Alternatively, the protective layer is provided with a groove, the outer surface of the heat pipe is provided with a temperature setting of the projection corresponding to the groove, the surface of the groove and the surface of the projections of the joint.
[15]
Alternatively, the positive electrode of the ear, the negative electrode tabs are respectively arranged at the two ends of the battery hole of the monomer on the end surface of the battery, the positive electrode ear, the negative electrode ear are symmetrically arranged.
[16]
Another purpose of the invention is to provide a battery module, the battery module includes a plurality of above any one wherein the single cell, a plurality of the single cell are arranged in a stack, each of said monomer the positive battery tab electrically connected with each other, each of said monomer of the battery is electrically connected with the negative electrode tab.
[17]
Optionally, adjacent the bottom surface of the monomer the anode of the battery, the negative pole of the adjacent battery is connected to the ear.
[18]
As to prior art, the application has the following beneficial effects:
[19]
An embodiment of the invention, monomer battery composed of a protective shell and located in the main body of the protective shell of the battery, the battery body formed by winding the winding structure, the battery body formed by the through hole of the body of the battery, the battery through hole used to manage the temperature. In this way, the monomer can be in the inside of the battery cooling it, thereby avoiding the single battery or external temperature difference is too big, greatly enhance the monomer battery or battery module working performance.
