Description
Technical field
The present invention relates to batteries of electric automobile group field, specifically is that a kind of batteries of electric automobile group is used electrode slice.
Background technology
The battery pack of electric automobile is made up of a plurality of monocells; Electrode slice is the assembly that the electrode with a plurality of monocells connects, and includes electrode group sheet and the electrode output chip that is used for connection electrode group sheet and single-cell electrodes as the one of which, and the horizontal plane of existing electrode output chip and electrode group sheet often is a planar structure; When electrode output chip and monocell are welded; Because the electrode tip of battery often is lower than the plane of electrode group sheet, so need stretching electrode output chip that itself and monocell are welded, this welding effect is poor; And the failure welding rate is high; And electric automobile vibration in the process of moving produces hard draw power to electrode slice and battery electrode, can cause coming off of electrode slice and battery electrode solder joint, influences battery performance.
Summary of the invention
The technical problem that the present invention will solve provides a kind of batteries of electric automobile group and uses electrode slice, solves the problem that conventional battery group electrode slice connects weak effect.
Technical scheme of the present invention is:
A kind of batteries of electric automobile group is used electrode slice; Include electrode group sheet and be used for the electrode connecting piece of connection electrode group sheet and single-cell electrodes, described electrode connecting piece comprise electrode input chip, the electrode output chip that is connected with electrode group sheet that is connected with single-cell electrodes and be connected in the electrode input chip and the electrode output chip between the transition electrode brace that bends of circular arc; The electrode input chip is parallel structure with the electrode output chip, and the horizontal plane of electrode input chip is lower than the horizontal plane of electrode output chip, and the horizontal level of the vertical peak of transition electrode brace is higher than the horizontal plane of electrode output chip.
The height such as horizontal plane of the horizontal plane of described electrode output chip and electrode group sheet.
Advantage of the present invention:
Transition electrode brace in the electrode slice has spring effect for the structure of bending when receiving external force, following advantage is arranged:
When (1), in battery pack manufacturing process, electrode being welded; When electrode group sheet and battery electrode have horizontal position difference; Because the transition electrode brace of circular arc bending has highly buffering; The electrode input chip is stretched under the battery electrode direction, thereby guaranteed welding reliability, reduce the deficient manufacturing procedure rate;
(2), electric automobile vibration in the process of moving, the spring effect of the transition electrode brace through circular arc bending obtains discharging, and has guaranteed the reliability of electrode pads effectively, has guaranteed the useful life of battery pack.
The present invention is simple in structure, the electrode slice convenient welding, has solved electric automobile in the process of moving because vibration causes the problem that comes off to electrode slice and single-cell electrodes solder joint.
