Embodiment 1

[0028] Such as Figure 1-3 As shown, a lithium battery pack with a balanced, steady flow and high heat dissipation includes a cylindrical housing 10, mounting grooves are provided on the front and rear end surfaces of the housing 10, and the housing 10 is provided with:

[0029] A plurality of battery rows 20 are equidistantly distributed around the axis of the casing 10, each battery row 20 is installed in the installation groove, and the battery row 20 is formed by connecting a plurality of lithium battery cells end to end in series; two rectifying plates 30 , two rectifying plates 30 are installed on the front and rear end surfaces of the casing 10 respectively, and are used to integrate and output the current of the battery rows 20. The rectifying plates 30 are coupled with each battery row 20 to form a path, and the front and rear rectifying plates 30 are respectively connected with the user The positive and negative electrical connections of electrical appliances;

Embodiment 2

[0036] Such as Figure 4-5 As shown, the difference between this embodiment and Embodiment 1 is that the central drum 40 and the movable drum 50 are all hollow, and the central drum 40 and the movable drum 50 are all filled with cooling liquid, and the cooling liquid can be For water or other liquids with a larger specific heat capacity, the end faces of the central drum 40 and the movable drum 50 are provided with a rotary joint 60 (for the prior art, not described in detail), and the movable drums 50 are communicated with each other through a connecting pipe 61 .

[0037] Concretely, the connecting pipes 61 between the movable drums 50 are connected from end to end in a direction in turn, and the connecting pipes 61 are distributed in a polygonal shape, and the connecting pipes 61 connect the multiple movable drums 50 together. When 50 rotates around the axis of the housing 1, the cooling liquid will flow into the lowermost movable drum 50 under the action of gravity. Since...

Abstract

The invention belongs to the technical field of lithium batteries, and particularly relates to a balanced current-stabilizing high-heat-dissipation lithium battery pack, which comprises: a cylindricalshell, wherein the shell is internally provided with a plurality of battery columns, the plurality of battery columns are equidistantly distributed around the axis of the shell, and each battery column is formed by connecting a plurality of lithium battery monomers end to end in series; two rectifying plates which are respectively arranged on the front end surface and the rear end surface of theshell and are used for integrating and outputting the current of the battery array; a plurality of limiting teeth which hare uniformly arranged on the inner side wall of the shell by taking the axis of the shell as the center; a plurality of pressure sensing pieces which are in one-to-one correspondence and are electrically connected with the battery columns, wherein when the pressure sensing pieces are extruded, circuits of the corresponding battery columns are connected, and the pressure sensing pieces and the limiting teeth are arranged alternately. According to the invention, each batterycolumn is communicated with the guide plate in sequence to realize intermittent work of each battery row, so that the heating of the battery rows can be effectively reduced, the battery columns can have a rest, and the service life of the battery is longer.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, in particular to a lithium battery pack with balanced, stable current and high heat dissipation. Background technique [0002] As lithium battery technology becomes more and more mature, there are more and more lithium battery application scenarios. Existing lithium batteries are generally densely arranged with multiple lithium battery cells. When in use, all lithium battery cells power supply at the same time. [0003] Because the existing batteries generate a lot of heat when they are in use, and the batteries are densely arranged, the heat is easy to accumulate in the casing. Over time, not only is it easy to cause the casing to age and swell due to heat, but it will also affect the service life of the battery. , to increase the failure rate of the battery. [0004] To this end, we propose a balanced steady current high heat dissipation lithium battery pack to solve the above probl...
