When working, only one or several unit battery packs are connected to supply power. When the power supply unit battery pack is exhausted and the electric vehicle needs to continue driving , just disconnect the power supply circuit of the unit battery pack that has been exhausted, and connect the other one or several unit battery packs to supply power. The workflow of the portable battery pack described above can be automated and displayed using a mechatronic device.

The technical scheme adopted by the utility model to solve the technical problem is: a portable battery pack, including two or more unit battery packs, two or more conductors, two or more single-control switches, a Or more than one positive pole of the power supply interface, one or more negative poles of the power supply interface, and each positive pole of the power supply interface corresponds to a negative pole of the power supply interface. The positive pole or the negative pole is connected to one or more single-control switches through a conductor. If the terminal at one end of the first single-control switch is connected to the positive pole of the first unit battery pack, then the terminal at the other end of the first single-control switch is connected to the terminal through a conductor. If the positive pole of the power supply interface is connected, then the negative pole of the corresponding power supply interface is connected to the negative pole of the first unit battery pack through a conductor. If the terminal at one end of the second single control switch is connected to the negative pole of the second unit battery pack, then the second single control switch The terminal at the other end is connected to the negative pole of the power supply interface through a conductor, then the positive pole of the corresponding power supply interface is connected to the positive pole of the second unit battery pack through a conductor. When any single-control switch is connected to the circuit, it is connected to this single-control switch The unit battery pack can supply power to the equipment through the positive pole of the power supply interface and the negative pole of the power supply interface connected to the unit battery pack. When any single control switch disconnects the circuit, the unit battery pack connected to it will not supply power to the equipment.

Above-mentioned portable battery pack, set the rated power, peak power, and working voltage value of any one unit battery pack or several unit battery packs working together at the same time as the numerical values suitable for electric vehicles, set any unit battery pack The total battery capacity of a group or several unit battery groups working together at the same time can support the normal driving of an electric vehicle for a certain distance.

The above-mentioned portable battery pack, the unit battery pack can be replaced by hand, its weight is not more than 20 kg, and its volume is not more than 0.2 cubic meters.

The beneficial effect of the utility model is that when the portable battery pack of the utility model is working, only one or several unit battery packs are connected to supply power. The power supply circuit of the exhausted unit battery pack is disconnected, and one or several other unit battery packs are connected to supply power. The exhausted unit battery pack can be taken out by hand, and the fully charged unit battery pack can be installed back by hand. The unit battery pack It can be obtained by directly charging the exhausted unit battery pack with the power socket at hand, or by exchanging the old for the new at the gas station in the service area, effectively bypassing the need for users to use electric vehicles to find charging piles and then drive the car to charge Next to the pile, and then consume the trouble of charging for a long time.
