Description
Technical field
The present invention relates to a kind of power supply, relate in particular to a kind of large multiplying power battery pack.
Background technology
Mainly there are following two kinds of defects in existing large multiplying power battery pack:
1. between battery and battery, be connected unreliablely, be subject to the easy Joint failure of impact of the large voltage of large electric current.
2. battery pack heat radiation is bad, and temperature rises too fast, easily occurs blowing.
Summary of the invention
For solving between existing large multiplying power battery cell and battery, be connected technical problem unreliable and that heat dispersion is bad, the invention provides a kind of large multiplying power battery pack reliable, good heat dissipation effect that connects.
The concrete technical solution of the present invention:
A multiplying power battery pack, comprises M*N battery, and its special character is: also comprise upper holder, lower fixed frame, a plurality of metal water conservancy diversion row;
The rectangular arrangement of a described M*N battery, wherein: every horizontally-arranged is arranged M battery, N battery of every tandem arrangement, the both positive and negative polarity placement direction of battery that is positioned at same horizontally-arranged is identical, and the both positive and negative polarity placement direction of the battery of adjacent two horizontally-arrangeds is contrary; Described metal water conservancy diversion row becomes battery unit by M the cell parallel that is positioned at same horizontally-arranged, and a plurality of metal water conservancy diversion rows connect N battery unit successively; M, N are the integer that is more than or equal to 2;
Fixed frame and lower fixed frame lay respectively at the both ends of the surface of large multiplying power battery pack, and fixed frame and lower fixed frame include M*N stopper slot, and a described M*N battery is fixed between the corresponding stopper slot of upper holder and lower fixed frame.
Spacing between above-mentioned arbitrary neighborhood stopper slot is slightly larger than the diameter of battery.
Between above-mentioned metal water conservancy diversion row's dual-side, be provided with outwardly guiding gutter, the structure of described guiding gutter and upper holder or lower fixed frame is suitable.
The above-mentioned metal water conservancy diversion row who is positioned on the outermost two row's batteries of large multiplying power battery pack is all protruding.
Laser welding between above-mentioned metal water conservancy diversion row's dual-side and the electrode of battery.
Above-mentioned metal water conservancy diversion row's material is nickel.
Beneficial effect of the present invention:
1, the large multiplying power battery pack of the present invention, by a plurality of batteries are carried out to certain arranging, thereby make adjacent two horizontally-arranged batteries only need just can reach by a strip metal water conservancy diversion row object of the cell parallel that is positioned at same horizontally-arranged, two battery series connection of same tandem being exported to large electric current; Simultaneously, use metal water conservancy diversion to arrange this connection means and have advantages of that reliability is high, water conservancy diversion is effective, be easy to welding, solved that the loss that at present large multiplying power battery pack causes under the condition of large voltage, large electric current is high, the high technical problem that easily causes partial failure of temperature.
2, the large multiplying power battery pack of the present invention, adopts metal water conservancy diversion row to carry out the connection in series-parallel between battery, be skillfully constructed, and the concave structure in the middle of metal water conservancy diversion row coordinates with battery mounting, is easy to locate.
3, the large multiplying power battery pack of the present invention, the groove on metal water conservancy diversion row not only plays the effect of location, and contributes to increase water conservancy diversion row's area of dissipation, prevents from, in battery power discharge process, superheating phenomenon occurs.
4, the large multiplying power battery pack of the present invention, limits the position of each battery by fixed mount, makes to keep certain gap between each battery, contributes to the heat radiation of single battery.
5, the large multiplying power battery pack of the present invention, metal water conservancy diversion row welds by laser with the both positive and negative polarity of battery, and welding resistance is little, has strengthened heat dispersion.
6, the large multiplying power battery pack of the present invention, is positioned at outermost two metal water conservancy diversion discharged to stretching out outward in a plurality of metal water conservancy diversion rows, is convenient to a plurality of arrangements of electric connections (being electrically connected to folder etc.) and is connected with outermost two metal water conservancy diversion row simultaneously, improves overcurrent capability.
