The technical solution of the utility model is as described below:
A kind of lithium battery bag, draw together the battery case in lithium battery incrustation and shell, each adjacent lithium battery in battery case is connected by integrated electric pole plate, inner lithium battery is made to be connected into an overall lithium battery group, also comprise space bar, fixed by space bar between described battery case and battery case, battery case is that multilayer laminar is arranged, and space bar is netted setting; Described lithium battery incrustation opposite end is respectively arranged with air inlet and air outlet, and air outlet place is provided with exhaust blower.
Further, described battery case and space bar are provided with air vent hole, inside described battery case, apply one deck electrolyte adsorption layer.
Further, described battery case and space bar material therefor are glass mat.
Further, described exhaust blower is connected with temperature-sensitive by-pass cock, temperature-sensitive by-pass cock is arranged in lithium battery incrustation.
Further, described lithium battery incrustation is also provided with electric-quantity display device, and electric-quantity display device is connected with lithium battery group; Described lithium battery incrustation is also provided with temperature indicator.
Further, described air inlet is provided with anti-dust filter mesh; The detachable setting of anti-dust filter mesh.
Compared with prior art, the beneficial effect had is:
Each charged lithium cells in lithium battery bag in battery compartment forms heat radiation gap each other, battery case and space bar arrange air vent hole, battery pack case is arranged air inlet and air outlet, heat distributes by heat radiation gap, air outlet by the heat produced when battery compartment can effectively work by this power brick, temperature-sensitive by-pass cock can carry out acceleration air draft according to internal temperature to inside simultaneously, make inside can accelerate to discharge for heat, radiating effect strengthens greatly, effectively extends the useful life of power brick.
