[0032] Working principle:

[0033] When using a battery pack to store photovoltaic energy, the wires on the inverter connected to the photovoltaic panel are connected to the connecting wires on the battery pack. The connecting wires can connect the positive and negative poles of multiple lead-acid battery cells 1 (the lead-acid battery cell 1 is an existing product sold on the market, and its specific method of storing electrical energy is an existing technology, which will not be described in detail here) in parallel and series. The photovoltaic panel converts light energy into electrical energy. After inversion by the inverter, the current can be used to power electrical appliances, and the excess electricity is input into the lead-acid battery cell 1 through the connecting wires for storage. When the lead-acid battery cell 1 needs to be replaced, the battery pack is taken out of the box 4, and then the worker squeezes the fixing rod 23 in the fixing groove 24 with his fingers. The fixing rod 23 has a certain toughness, so that one end of the fixing rod 23 is pressed down, and then the U-shaped rod 1 21 is dragged to connect with the U-shaped rod 2 2, then separate the connecting wires and the electrodes, and then replace them, so as to achieve the purpose of replacing the lead-acid battery cell 1 as much as possible. By setting the sliding surface 1 25 and the sliding surface 2 26, the auxiliary fixing rod 23 is inserted into the fixing groove 24. By setting the magnetic piece 1 27 and the magnetic piece 2 28, they attract each other when close to each other, thereby assisting in fixing the fixing rod 23. When the connecting wires are fixed to the positive and negative electrodes of the lead-acid battery cell 1, the fixing column 31 is a conductive metal. The worker inserts the wire into the cross hole 32 and twists the screw rod 36. Under the limit rod 35, the extrusion plate 34 moves downward, so that the wire squeezed into the cross hole 32 is fixed. Then, the other connecting wire is fixed to the other fixing column 31 in the same way. By setting the heat insulation board 5, the working heat of the lead-acid battery cells 1 is prevented from affecting each other. The screw rod 36 and the limit rod 35 are insulating rods.
