Abstract
The utility model discloses a battery pack array structure good for heat dissipation, which can be applied for a battery pack assembled from rechargeable single cells. The battery pack array structure comprises at least two single cells with the electrodes connected in series and each single cell is connected at the one tenth to nine tenths position of the side face of the adjacent single cell. The battery pack array structure is simple in structure, and the heat dissipation area is effectively increased, so the heat produced by the parts of the battery can be dissipated timely. The utility model keeps a good working condition for the battery, reduces the temperature rise of the battery during work and the performance difference of the battery caused by the temperature of the working environment, ensures the consistency of the temperature of the battery, improves the performance and the reliability of the battery and prolongs the service life of the battery.
Description
Technical field
The utility model relates to a kind of battery pack, but the arrangement architecture the when cell that relates in particular to various rechargings is combined into battery pack.
Background technology
In recent years, along with the high speed development of information and electronic technology, various storage batterys are used widely in fields such as communication, electric power, power.But problems such as often because to the unreasonable use of storage battery, the electrolyte that has produced storage battery is dry, thermal runaway, early stage capacitance loss, internal short-circuit, and then badly influence the performance of battery.In all environmental factors, temperature has the greatest impact to the charge-discharge performance of battery.With the capacity series battery, with identical discharge rate, when the certain environment temperature range was discharged, the use capacity raises with temperature to be increased, and reduced with temperature to reduce.But, surpass certain temperature range, then opposite, as discharging under 45～50 ℃ of conditions of ambient temperature, then battery capacity obviously reduces.The performance of rechargeable battery material can be degenerated under the high temperature, and battery cycle life also will shorten greatly.The frequency ratio that the terminal use changes battery obviously improved in the past, caused the significantly rising of use cost.Temperature not only influences the capacity of battery, and influences the life-span of battery, causes battery failure.So radiating mode has very large influence to battery performance.Good heat dissipation then battery performance can be good at performance and the life-span long, can reduce because of the cost that increases of replacing battery.Traditional battery combination mode all is that battery is arranged side by side.The mode that is arranged side by side, its area of dissipation is minimum.Only there are two batteries in next door to can be good at heat radiation.
Summary of the invention
Battery-arrangements is unfavorable for heat radiation to the utility model in the existing battery pack in order to solve, easily cause the defective of shorter battery life, a kind of battery pack arrangement architecture that is beneficial to heat radiation is provided, and it is by the battery-arrangements structure being provided with effective raising radiating effect, and is simple in structure, practical.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of battery pack arrangement architecture that is beneficial to heat radiation, include the cell of at least two electrode serial or parallel connections, each cell is connected to the position of adjacent monomer battery side 1/10 to 9/10.
Described cell two electrodes are positioned at battery top, connect by lead between the electrode of each battery.
Described cell is provided with four altogether, and wherein upper end, the side of cell one and cell three is connected the lower end of the left and right side of cell two separately, and the left surface lower end of cell four is connected the right flank upper end of cell three.
Described cell is the rectangular body shape, and the positive electrode of cell one is connected with the negative electrode of cell two, and the positive electrode of cell two is connected with the negative electrode of cell three, and the positive electrode of cell three is connected with the negative electrode of cell four; Each cell links to each other with adjacent half side of a cell respectively.
Described four these unit of cell primordial, elementary cell is by laterally or longitudinally being combined to form array.
The utility model increases area of dissipation by each cell dislocation is separated arrangement indirectly, and its advantage has:
1, described structure can make storage battery prolong useful life in identical hot environment;
2, avoided storage battery as far as possible because the too high capacity decline problem that causes of temperature;
3, contrast the phenomenon that can reduce the battery thermal runaway to greatest extent with the conventional arrangement mode;
4, reduce battery because operating ambient temperature influences the otherness of performance, guaranteed the consistency of battery temperature, improved battery performance and reliability.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the structural representation of the utility model preferred embodiment.
Embodiment
Be beneficial to the preferred embodiment of the battery pack arrangement architecture of heat radiation as shown in Figure 1, be provided with four cells altogether, cell is a rectangular shape, and positive electrode 01, negative electrode 02 all are positioned at battery top.Wherein upper end, the side of cell 1 and cell 3 05 is connected half area place, lower end of the left and right side of cell 2 04 separately, and the left surface lower end of cell 4 06 is connected half area place, right flank upper end of cell 3 05; Wherein cell 1 and cell 3 05 side by side, cell 2 04 and cell 4 06 are side by side.The positive electrode 01 of described cell 1 is connected with the negative electrode 02 of cell 2 04, and the positive electrode 01 of cell 2 04 is connected with the negative electrode 02 of cell 3 05, and the positive electrode 01 of cell 3 05 is connected with the negative electrode 02 of cell 4 06; Connect by lead between the electrode of described each battery.
Cell also can be a shape such as cylindrical, the battery electrode serial or parallel connection; Four cells constitute elementary cell, and this elementary cell can be again by laterally or longitudinally being combined to form bigger array.Certain described elementary cell is provided with quantity and is not limited to four, can be two three even more than four.One contacts side surfaces area of each cell and adjacent monomer battery can the gross area 1/10 to 9/10 between (being 1/2 in the preferred embodiment).Cell can be connected adjacent monomer battery sidepiece on the upper side/below, in like manner also can be sidepiece take back/right-hand.
In the utility model structure, each cell is not to be close together fully as the conventional batteries combination, but separates indirectly, increases area of dissipation.Area of dissipation has increased, and the heat that each several part produced when battery operated is pulled away rapidly, and battery and operational environment radiating effect thereof are better.Battery heats up when having reduced work, has reduced battery because operating ambient temperature influences the otherness of performance, has guaranteed the consistency of battery temperature, has improved battery performance and reliability, has prolonged the useful life of battery.
