Description
Technical field
The utility model relates to a kind of battery pack structure of electric automobile.
Background technology
The battery pack structure of existing electric automobile, multiple solder joint is had between monomer whose lithium battery and positive and negative electrode conductive plate, multiple solder joint needs to adopt multiple spot welding means of spot welds mode to weld, series spot welding refers to when there being two contacts site in a welding current loop, electric current will carry out spot welding by these two contacts site in order successively, but generation current distributary phenomenon sometimes, only have and just can be prevented current efficiency from reducing by as far as possible high current thus be ensured the welding quality of workpiece to be welded, high current easily causes damage to battery.
Summary of the invention
The purpose of this utility model provides a kind of battery pack structure of electric automobile.
The utility model is made up of multiple single lithium battery, positive conductive connecting plate and negative conductive connecting plate, positive pole and the positive conductive connecting plate of multiple single lithium battery weld together, negative pole and the negative conductive connecting plate of multiple single lithium battery weld together, the positive pole of each single lithium battery and positive conductive connecting plate have two solder joints, and the negative pole of each single lithium battery and negative conductive connecting plate have two solder joints.
Described single lithium battery welds together in the mode of the parallel spot welding of monolateral two point with between positive conductive connecting plate and negative conductive connecting plate.
The beneficial effects of the utility model: respectively have two solder joints between single lithium battery of the present utility model and positive and negative electrode conductive plate, two solder joints weld in the mode of the parallel spot welding of monolateral two point, ensure that welding quality, also can not cause damage to battery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Refer to shown in Fig. 1, the present embodiment is made up of 28 single lithium battery 1, positive conductive connecting plate 2 and negative conductive connecting plate 3, positive pole and the positive conductive connecting plate 2 of multiple single lithium battery 1 weld together, negative pole and the negative conductive connecting plate 3 of multiple single lithium battery 1 weld together, the positive pole of each single lithium battery 1 and positive conductive connecting plate 2 have two solder joints, and the negative pole of each single lithium battery 1 and negative conductive connecting plate 3 have two solder joints.
Described single lithium battery 1 welds together in the mode of the parallel spot welding of monolateral two point with between positive conductive connecting plate 2 and negative conductive connecting plate 3.Simultaneously the mode of the parallel spot welding of monolateral two point utilizes the welding transformer at electrode two ends to treat welder's part to carry out two point welding, effectively can reduce the generation of current distributing phenomenon compared with series spot welding.Due to structure and the characteristic thereof of core of lithium ion cell product, in order to realize welding between battery with brace, adopting direct spot welding to compare and being difficult to, adopting monolateral two point parallel spot welding mode to be rational.
