The invention utilizes two metal materials with different thicknesses and characteristics to be mutually jointed to form a battery connecting guide sheet, which not only can effectively reduce the welding difficulty between the battery and the connecting guide sheet, but also can be used for passing large current during the charging and discharging of the battery and helping the heat during the charging and discharging of the battery to be quickly dissipated.
Description
Technical field
The present invention relates to a kind of battery and connect guide card, relate in particular to a kind of utilization neither the battery made of same material connect guide card.
Background technology
Battery, be generally used on the portable mobile device, for making the battery of general capacity can supply large-scale mobile device required electric power, as: electric motor car, certainly will or be connected in parallel a plurality of battery series connection, forming one can be for the battery module of high current charge-discharge.Generally with the battery serial connection or and the wherein method that connects be to utilize one to connect the guide card cross-over connection between the electrode of adjacent two batteries, and utilize welding manner to connect this connections guide card and these a plurality of batteries form a current circuit.
Cooperate and consult Fig. 8, connect the stereogram and use schematic diagram of guide card for existing battery.The material of general battery 200 housings (comprising the electrode part) is generally pure nickel, iron nickel plating or aluminium, mainly directly contacts with extraneous in order to the active material of avoiding battery 200 inside; If directly use connects guide card 100 with the battery of the identical material of battery 200 housings, its advantage is that electrode 210 welds easily with being connected guide card 100, but because the conductivity of above-mentioned material is relatively poor, so and be not suitable in the battery module of high current charge-discharge.
The general normal battery that is used in the high current charge-discharge battery module connects guide card 100 for copper material, because the conductivity of copper material itself is good; Because the big electric current when needing the supply battery module to discharge and recharge passes through, and therefore must increase the thickness that copper connects guide card, more to promote the characteristic of its conduction, has increased battery 200 and has been connected 100 liftings of welding difficulty of guide card and the increase of thickness is corresponding also.Its main cause is when the thickness that connects guide card 100 increases, required electric current needs relative healing greatly during welding, and weld stress also need be healed greatly, so cause the control of process parameters degree of difficulty to promote, and fusion temp required during welding is also difficult concentrated because of the big temperature that causes of area of heat radiation, and then makes welding quality wayward.
In addition, because copper itself also has good thermal conductivity, therefore in welding process, copper can be got rid of its surperficial temperature apace, therefore causes temperature to be difficult for the problem of concentrating in welding process, improves the difficulty of welding.
Therefore, how to provide one to have satisfactory electrical conductivity, thermal conductivity and the battery that is easy to be connected with battery 200 connects guide card 100 in the battery module of high current charge-discharge, desire most ardently for industry at present and overcome and improved problem.
