Background
With the increasing shortage of energy sources, lithium battery packs are widely applied in various fields. At present, lithium battery packs in the market are all rectangular or square, and a whole lithium battery pack is placed in an inner space. The lithium battery pack can generate a large amount of heat to be accumulated in the center of the battery in the charging and discharging processes, although the charging and discharging protection plate is arranged in the lithium battery pack, the heat in the overcharging or overdischarging process rises more quickly, and the whole heat is conducted more slowly, so that the heat generation and deformation in the battery can be caused frequently; the long-term use can lead to the accelerating of electric core ageing, and serious can lead to the lithium cell group to scrap or take place the installation hidden danger.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above disadvantages, an object of the present invention is to provide a novel safety lithium battery pack
In order to achieve the purpose, the lithium battery pack comprises an outer box body made of first metal, wherein an insulating box cover is arranged on the outer box body, and two electrodes are arranged on the insulating box cover; a plurality of heat-conducting partition plates made of second metal are arranged in the outer box body;
a plurality of heat pipe holes are formed in the surface of one side, close to the insulating cover, of the heat conduction partition plate, and heat pipes are arranged in the heat pipe holes; the heat absorption end of the heat pipe is arranged in the heat pipe hole, and the heat release end of the heat pipe penetrates through the insulating box cover and extends out of the insulating box cover; a metal radiating fin is arranged on the heat release end of the heat pipe;
the outer box body is divided into a plurality of battery chambers by the heat-conducting partition boards; a plurality of soft-package rectangular lithium batteries are arranged in the battery chamber; the soft-package rectangular lithium battery in each battery room is connected in parallel and/or in series to form a sub-battery pack, and each sub-battery pack is connected in parallel and/or in series to be connected with two electrodes on the insulating box cover; wherein, a temperature control switch is connected in series on at least one electrode lead-out wire of each sub battery group.
Preferably, a cooling fin is arranged between two adjacent soft-package rectangular lithium batteries.
The utility model discloses an adopt means such as metal box, metal heat conduction baffle, heat pipe, metal heat radiation fins, with the better effluvium of heat that soft packet of rectangle lithium cell produced at the charge-discharge in-process to prevent the battery because the deformation that produces generates heat, prolonged the life of product, solved the potential safety hazard.
