In order to achieve the purpose, the utility model provides the following technical scheme: an ultra-light battery pack for ensuring the safety of a battery comprises a battery core 1, wherein the battery core 1 is arranged between a front hollow plate 2 and a rear hollow plate 2, and the rear end of each hollow plate 2 is provided with a fan 3;

the plastic end plates 12 are symmetrically arranged at the left side and the right side of the battery core 1;

96 battery cores 1 are arranged, and the bottom surface of each battery core 1 is bonded with the bottom heat-conducting structural adhesive 5 and the bottom heat-insulating pad 6;

the top surface of each battery core 1 is bonded with top heat-preservation foam 10 through heat-conducting structural adhesive 8 and upper sealant 9, and a mica plate 11 is arranged on the upper portion of the top heat-preservation foam 10.

And a bottom sealant 4 is arranged at the gap of the bottom surface of the battery core 1.

The top surface of the battery core 1 is provided with a top insulating strip 7 at the gap.

Compared with the prior art, the utility model has the beneficial effects that: this ensure ultra-light battery package of battery security, in the in-service use process, install the battery core in the centre of fretwork board, because the hollow out construction of fretwork board, combine the effect of fan, make the air form the convection current, reach ventilation cooling's effect, and the battery core group does not have the lock and attaches, utilize bottom and top sticky and fuselage to form a whole, as the longeron of box, overall structure is compact, light in weight, the battery core is crust rectangle electricity core, the casing is uncharged, anodal utmost point post and casing are insulating, insulating nature is good, the security has been improved.

1. The battery pack is provided with the battery core, the hollow plate and the fan, the battery core is arranged in the middle of the hollow plate, and the battery core can be cooled by combining the hollow shape of the hollow plate and the arrangement of the fan, and the battery core is a hard-shell rectangular battery core, the shell is not electrified, the positive pole column is insulated from the shell, the insulativity is good, the safety of the battery pack is improved to a certain extent, and the practicability is high;

2. be equipped with bottom heat preservation pad, top heat preservation bubble cotton, mica plate, use the heat preservation bubble cotton under the mica plate, combine the setting of bottom heat preservation pad for the outside temperature of battery core is in comparatively invariable state, simple structure, and the practicality is high.
