The distance between the two connection points can be adjusted, and the mesh structure is suitable for transmitting large currents.

Preferably, the side of the box is provided with cooling grids, and the upper ends of the two sides of the box in the width direction are provided with threading holes. After the battery is placed in the box, it is convenient to charge through the threading hole on the side of the box; the heat dissipation grid makes the battery dissipate heat quickly, reduces the temperature of the battery, and stabilizes the transmission of battery power.

Rotatable handles are also provided on the upper ends of the two box body surfaces in the width direction.

A projection is fixed on one end of the plane on the cover plate, and the cover plate can be drawn out from the guide groove along the length direction.

12 independent batteries can be installed in the box, the width of the box matches the length of the batteries, and the length of the box matches the overall thickness of the 12 independent batteries.

There are connection holes on the upper part of the side of the box in the length direction, and matching connection holes are provided at the corresponding positions of the bead. The height of the connection hole matches the height of the independent battery after the bead is installed. The bead and the side of the box are bolted. fixed.

The bead is L-shaped, the long side of the bead is in contact with the side of the casing, the connecting hole is arranged on the long side, and the short side of the bead is in contact with the independent battery and compresses the independent battery.

There are two pairs of gaps at the flange, the length of the gap matches the width of the independent battery, and the distance between the two pairs of gaps matches the length of the independent battery; the support bar is an angle iron, and is broken at the gap , the inside of the box is straight from the notch to the bottom of the box. There are no protrusions on the vertical surface of the gap in the inner wall of the box, so that the independent battery can be put in smoothly, making the overall structure compact and saving space.

The beneficial effect of the utility model is: adopting a standard box body makes the power unit of the electric vehicle unified, easy to replace, no other supporting special charging device is needed, and the cost is saved.
