Abstract
The utility model provides a voltage acquisition wire of a lithium ion battery module, comprising an aluminum electrode and a wire, wherein the aluminum electrode and the wire are fixedly connected through a wire crimping terminal. The aluminum electrode and the wire are connected through the wire crimping terminal in a crimping method, the wire crimping direction of the wire crimping terminal avoids a minimum-section area of the aluminum electrode, the tensile strength of the voltage acquisition wire after crimping is greatly increased, the problem of tensile failure caused by insufficient tensile strength of aluminum material is avoided, the reliability of connection between the aluminum electrode and the wire is increased, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of lithium ion battery module group, is specifically related to a kind of voltage acquisition line of lithium ion battery module.
Background technology
Because little, the noiselessness of lithium battery environmental pollution, energy advantages of higher, now be used as the power source of new-energy automobile, its groundwork principle is to provide electric energy by the lithium ion battery module to motor, the drive motor running, thus propelling vehicle advances.Be that lithium battery by some forms high-power, jumbo lithium ion battery module group by being together in series as the power source of electric automobile.
Along with the development of pure electric vehicle and hybrid vehicle, be a key factor that influences vehicle performance as the series battery of important energy storage device.The service efficiency of extending battery life, raising battery is the key of electric automobile commercialization, practicability.Because the existence of bucket effect, the overall performance of series battery depends on the poorest cell of performance in the battery pack, effectively manages in order to use the energy of series battery, needs the cell state in the real time monitoring series battery.In the parameter of characterizing battery state, the terminal voltage of battery best embodies its operating state, and therefore each monomer battery voltage is very important in the accurate collection battery pack.In order to detect the voltage of each cell in the battery pack, need a voltage acquisition line be set at positive pole and the negative electrode of battery pack, the voltage acquisition line mainly adopts soldering technology that lead and aluminium electrode are linked together (as shown in Figure 1), because the solderability of aluminium and two kinds of materials of tin is very low, cause soldering reliability and consistency relatively poor, and weld defect check difficulty is very big.Therefore the electrical connection that produces was lost efficacy and can be produced serious consequence in the product use, greatly increased the maintenance cost of product.In addition, soldering mode solder joint is not firm, easily come off, and since the tin welding spot of lead and aluminium electrode at the near-end of battery electrode, also can cause tin welding spot to come off, and cause the voltage that can't detect cell voltage or detection inaccurate.
The utility model content
The purpose of this utility model just provides a kind of voltage acquisition line of lithium ion battery module, the voltage acquisition line is connected stablize, detect cell voltage purpose accurately.
In order to reach above-mentioned effect, the utility model provides a kind of voltage acquisition line of lithium ion battery module, comprises aluminium electrode and lead, and described aluminium electrode and lead are affixed by pressure line terminal.
The preferred version of such scheme is, described aluminium electrode one side is provided with crossed beam trunking, and an end of described lead penetrates in the described crossed beam trunking by pressure line terminal that it is affixed.
First with equipment crossed beam trunking of side blow extrusion with the aluminium electrode in the utility model, end with lead penetrates in the crossed beam trunking then, again pressure line terminal is enclosed within the external port of crossed beam trunking, use the whole crimping of Crimping Pliers, pressure line terminal is fixed crossed beam trunking and the lead integral body that is through in the crossed beam trunking, has so just formed the voltage acquisition line of lithium ion battery module.
Voltage acquisition line of the present utility model adopts the mode of crimping that aluminium electrode and lead are coupled together by pressure line terminal, the line ball direction of pressure line terminal is avoided aluminium electrode sections Minimum Area, greatly increase the tensile strength of voltage acquisition line after the crimping, thereby avoided the not enough and tension Problem of Failure that causes of the tensile strength of aluminium material own.In addition, the utility model greatly increases the reliability that the aluminium electrode is connected with lead, and enhances productivity.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is voltage acquisition line structure schematic diagram of the prior art;
Fig. 2 is voltage acquisition line structure schematic diagram of the present utility model;
Fig. 3 is the aluminium electrode structure schematic diagram in the utility model;
Among the figure: 1-lead, 2-aluminium electrode, 3-pressure line terminal, 4-crossed beam trunking.
Embodiment
As Fig. 2, shown in Figure 3, a kind of voltage acquisition line of lithium ion battery module, comprise aluminium electrode 2 and lead 1, described aluminium electrode 2 one sides are provided with crossed beam trunking 4, one end of described lead 2 penetrates in the crossed beam trunking 4, pressure line terminal 3 is enclosed within the external port of crossed beam trunking 4 again, uses the whole crimping of Crimping Pliers, pressure line terminal 3 is fixed crossed beam trunking 4 and lead 2 integral body that are through in the crossed beam trunking 4, has formed the voltage acquisition line of lithium ion battery module.
Voltage acquisition line of the present utility model adopts the mode of crimping that aluminium electrode and lead are coupled together by pressure line terminal, the line ball direction of pressure line terminal is avoided aluminium electrode sections Minimum Area, greatly increase the tensile strength of voltage acquisition line after the crimping, thereby avoided the not enough and tension Problem of Failure that causes of the tensile strength of aluminium material own.In addition, the utility model greatly increases the reliability that the aluminium electrode is connected with lead, and enhances productivity.
Above embodiment is not limited only to protection range of the present utility model, all make amendment based on basic thought of the present utility model or change all belong to protection range of the present utility model.
