When a plurality of rows of battery cores are arranged in the battery box, the air cooling groove can enable the adjacent two rows to form a ventilation channel communicated with the cooling channel (formed by the gap between the two adjacent contact bulges after the two adjacent battery core supports are contacted), and under the action of the ventilation fan, air entering the air cooling channel from the air inlet hole on the side surface of the box plate flows out of the battery box through the ventilation channel, so that the effective heat dissipation of the battery cores is ensured.

Compared with the prior art, the utility model, have following advantage:

the limiting blocks are embedded into the limiting grooves, so that the movement of the battery box is limited, and the possibility that the battery box falls off from the battery rack is avoided. Through the cooperation of air outlet and ventilation fan, can derive the hot-air in the battery box, avoid electric core temperature to rise.

Through the cooperation of spacing support and stopper, can guarantee that the battery box is spacing fixed by in the battery frame, also compromise convenient assembling, the swift of battery box and battery frame simultaneously, later stage dismantlement maintenance convenience.
