Specifically, in a first output state, a positive input terminal B + of the electric device is sequentially inserted into the first positive terminal B1+, the second positive terminal B2+, the third positive terminal B3+, and the fourth positive terminal B4+, so that the first positive terminal B1+, the second positive terminal B2+, the third positive terminal B3+, and the fourth positive terminal B4+ are conductively connected, that is, the positive electrodes of the four batteries are connected in parallel; the negative input terminal B-of the electric equipment is sequentially inserted into the first negative terminal B1-, the second negative terminal B2-, the third negative terminal B3-and the fourth negative terminal B4-, so that the first negative terminal B1-, the second negative terminal B2-, the third negative terminal B3-and the fourth negative terminal B4-are in conductive connection, namely, the negative electrodes of the four batteries are connected in parallel. At this time, the four batteries are output in parallel with each other, i.e., the small voltage output of the battery pack 100. Such as: when the voltages of the four batteries are all 18V, the first voltage is 18V.
As shown in fig. 3, in the second output state, the first battery B1, the second battery B2, the third battery B3 and the fourth battery B4 are connected in series in sequence, the first positive terminal B1+ is configured as the positive output of the battery pack 100, the fourth negative terminal B4-is configured as the negative output of the battery pack 100, and the second voltage is suitable to be output between the positive output and the negative output. Specifically, the battery pack 100 further includes: a fifth positive terminal B5+ and a fifth negative terminal B5-, the fifth positive terminal B5+ being electrically connected to the second positive terminal B2+, the fifth negative terminal B5-being electrically connected to the first negative terminal B1-; a sixth positive terminal B6+ and a sixth negative terminal B6-, the sixth positive terminal B6+ being electrically connected to the third positive terminal B3+, the sixth negative terminal B6-being electrically connected to the second negative terminal B2-; a seventh positive terminal B7+ and a seventh negative terminal B7-, the seventh positive terminal B7+ being electrically connected to the fourth positive terminal B4+, the seventh negative terminal B7-being electrically connected to the third negative terminal B3-; in the second output state, the second connection portion 300 of the electric device has three conductors, which electrically connect the fifth positive terminal B5+ and the fifth negative terminal B5-, the sixth positive terminal B6+ and the sixth negative terminal B6-, and the seventh positive terminal B7+ and the seventh negative terminal B7-, respectively. This corresponds to connecting four batteries inside the battery pack 100 in series in order through three conductors. At this time, the four batteries are serially connected to each other to output, i.e., the battery pack 100 outputs a large voltage. Such as: when the voltages of the four batteries are all 18V, the second voltage is 72V.
As shown in fig. 4, in the third output state, the first battery B1 and the second battery B2 are connected in parallel as the first battery B1 group, the third battery B3 and the fourth battery B4 are connected in parallel as the second battery B2 group, and the first battery B1 group and the second battery B2 group are connected in series, the first positive terminal B1+ and the second positive terminal B2+ are commonly configured as the positive output of the battery pack 100, the fourth negative terminal B4-and the third negative terminal B3-are commonly configured as the negative output of the battery pack 100, and a third voltage is suitable to be output between the positive output and the negative output.

Specifically, the battery pack can be realized by two long insertion pieces (male insertion pieces), and the long insertion pieces need to reach a first short-circuit terminal B10-and a second short-circuit terminal B10+ in the battery pack 100.
In a third output state, the first battery B1 and the second battery B2 are connected in parallel to form a first battery B1 group; the third battery B3 and the fourth battery B4 are connected in parallel to form a second battery B2 group; the two battery packs are then connected in series to output a voltage, i.e., a medium voltage output of the battery pack 100. Such as: when the voltages of the four batteries are all 18V, the parallel connection voltage of the first battery B1 and the second battery B2 is 18V, the parallel connection voltage of the third battery B3 and the fourth battery B4 is 18V, and then the parallel connection voltage of the two groups of battery packs is 36V after the two groups of battery packs are connected in series, so that the third voltage is 36V.

And the first short circuit terminal B10-and the second short circuit terminal B10+ are also fixedly arranged in the battery pack 100, and each terminal is fixedly arranged in the battery pack 100, so that the battery pack is not easy to loosen in the repeated plugging process of the electric equipment, has good contact and good plugging resistance effect.
