With the development of new energy technology, the application fields of batteries are becoming more and more extensive. For example, batteries can be used as a power source to provide power for electrical equipment and reduce the use of non-renewable resources. When the power of the battery in the electrical equipment is not enough to support the continued driving of the electrical equipment, charging equipment such as charging piles can be used to charge the electrical equipment, that is, to charge the battery in the electrical equipment to achieve battery charging. , discharge cycle use. However, battery charging takes a long time, which limits the battery life of electrical equipment.

In order to improve the battery life of electrical equipment, battery replacement technology came into being. Battery swapping technology adopts the method of "vehicle and battery separation", which can provide battery replacement services for electrical equipment through battery swapping stations, that is, the battery can be quickly removed or installed from the electrical equipment. The batteries removed from the power-consuming equipment can be placed in the power-swapping cabinet of the power-swapping station for charging in preparation for power-swapping of the power-consuming equipment that subsequently enters the power-swapping station.

In the current conventional technology, the entire process of replacing batteries of electrical equipment is performed in series. Specifically, after the electric equipment is parked on the power exchange platform, the device for replacing the battery moves to the electric equipment, and the battery to be removed is removed from the electric equipment. Then, the battery to be disassembled is transported to a battery storage mechanism (such as a charging compartment or a battery cache device).

When the electrical equipment 12 installed with the battery 141 drives into the power swap station 11, the power swap station 11 removes the battery 141 from the electrical equipment 12 through the power swap device, takes out the battery 142 from the power swap station 11, and then installs the battery 142 Go to the electrical equipment vehicle 12. Afterwards, the electrical equipment 12 with the battery 142 installed can drive away from the power swap station 11 . Through this power swap technology, power-consuming equipment can be quickly replenished with energy within a few minutes or even tens of seconds, improving the user experience.

As shown in FIG. 1 , a power swap cabinet 13 may be provided in the power swap station 11 . The power swap cabinet 13 includes a battery management unit (battery management unit, BMU) 131. In addition, the power swapping cabinet 13 may also be provided with multiple charging compartments 132, and batteries used for power swapping may be placed in the charging compartments 132.

The power swap station 11 may also be provided with a corresponding management device. The management device may have a centralized structure or a distributed structure, which is not limited here. The management device can be installed inside the power swap station 11 or outside the power swap station 11 .

For another example, the station control system 151 can also communicate with the cloud server 152 to obtain relevant information about the battery 141 on the electrical device 12 or the battery 142 in the charging compartment 133 .

FIG. 2 shows a schematic flow chart of a battery replacement method 200 according to an embodiment of the present application. Method 200 may include at least some of the following.

S210, control the disassembly of the battery to be disassembled by the electrical equipment, and the disassembly of the vehicle is one of the first vehicle and the second vehicle.

S220, after the disassembly drive has removed the battery to be disassembled and the disassembly drive is controlled to transport the battery to be removed to the charging bin, the installation drive is controlled to install the battery to be installed on the electrical equipment. The installation drive is the first drive and the second drive. Another of the two trains.

Method 200 can be applied in a battery swap station. As mentioned above, the battery swap station can be a fixed place or a movable place. Method 200 may be executed by a management device in a battery swapping station, for example, by a station control system, such as the station control system 151 in Figure 1 . For example, after the electrical equipment is parked in the power swap channel of the power swap station, the station control system may execute method 200.

The station control system can communicate with the first traveling vehicle and the second traveling vehicle in a wireless manner to execute method 200. For example, the first vehicle and the second vehicle are communicated through wireless communication methods such as Bluetooth communication, WIFI communication or ZigBee communication.

Optionally, the battery to be removed can be a depleted battery, and the battery to be installed can be a fully charged battery.

Alternatively, the battery to be disassembled may be an abnormal battery, such as a battery that has experienced thermal runaway, or a battery that is deformed in shape. At this time, the battery to be installed can also be a fully charged battery, or it can also be a battery with the same power as the battery to be removed, but without thermal runaway or shape deformation.

The electrical equipment can be an electric vehicle, a ship or a spacecraft, etc. The electric vehicle may be, for example, a heavy-duty truck, such as a sprinkler truck, a fire truck, an earth-moving truck, a truck, etc. According to analysis, the overall heavy-duty truck market has about 7 million units, and more than 70% of heavy-duty trucks operate 24 hours a day (two or three shifts). In this case, the electrical equipment is a heavy-duty truck, which can improve the use experience of heavy-duty trucks. And for heavy-duty trucks, compared to charging, the battery swap mode can effectively solve the pain points of scarcity of charging parking spaces, large battery capacity, and long charging time.

The shapes and sizes of the first carriage and the second carriage may be the same or different, and this is not specifically limited in the embodiment of the present application.

Communication is possible between the first train and the second train. For example, communication between the first train and the second train can be through wired or wireless means.

It should be understood that in the embodiments of the present application, “first” and “second” are only used to distinguish different objects, but do not limit the scope of the embodiments of the present application.

The charging compartment is a device that can charge the battery. For example, it can be the charging compartment 132 in Figure 1 . A battery swap station may include multiple charging bays.

In some embodiments, charging compartments may be provided on both sides of the battery exchange channel.

Wherein, at least one charging compartment can be provided on each side of the power exchange channel. The number of charging bins provided on both sides of the power exchange channel can be the same or different.

In some embodiments, method 200 may further include: determining a disassembly run and an installation run in the first run and the second run.

This technical solution determines the disassembly and installation of the first carriage and the second carriage, which can avoid the problem of conflict between the first carriage and the second carriage during the power exchange process, such as disassembly of both the first carriage and the second carriage. The battery or battery installation operation is performed, which advantageously ensures the smooth progress of battery replacement.

By way of example, the disassembly operation and the installation operation can be determined arbitrarily between the first operation and the second operation.

As another example, one of the first carriage and the second carriage may be fixed as a disassembly carriage, and the other may be fixed as an installation carriage. For example, the first carriage can be fixed as a disassembly carriage, and the second carriage can be fixed as an installation carriage.

As another example, the first carriage and the second carriage may alternately serve as a removal carriage and an installation carriage. For example, when replacing the battery of the previous electrical equipment, it is determined that the first operation is the disassembly operation and the second operation is the installation operation. Then, when replacing the battery of the current electrical equipment, the first driving operation is determined as the installation operation, and the second operation is determined as the disassembly operation.

As another example, the disassembly operation and the installation operation can be determined in the first operation and the second operation according to the direction in which the electrical equipment enters the battery swap station.

Determine the disassembly and installation operation according to the direction in which the electrical equipment enters the battery swapping station. In this way, the location of the battery of the electric equipment is convenient for the disassembly operation of the operation of disassembling the battery to be removed, and is convenient for the installation operation of the installation operation of the battery to be installed. This further simplifies the complexity of battery replacement and further improves the efficiency of battery replacement.

Specifically, if the electrical equipment enters the battery swap station from the entrance direction of the battery swap station, the first vehicle can be determined as a disassembly vehicle and the second vehicle can be determined as an installation vehicle. At this time, the first driving position is convenient for removing the battery of the electrical equipment, and the second driving position is convenient for installing the battery of the electrical equipment.

If the electrical equipment enters the battery swap station from the exit direction of the battery swap station, the first drive can be determined as the installation drive, and the second drive can be determined as the disassembly drive. At this time, the position of the first traveling vehicle is convenient for installing the battery of the electrical equipment, and the position of the second traveling vehicle is convenient for removing the battery of the electrical equipment.

Optionally, the first traveling vehicle and the second traveling vehicle may be located on both sides of the power exchange channel respectively.

For example, along the direction from the tail to the head of the electrical equipment, the first carriage can be located on the left side of the power exchange channel, and the second carriage can be located on the right side of the power exchange channel. Alternatively, the first traveling vehicle may be located on the right side of the power exchange channel, and the second traveling vehicle may be located on the left side of the power swapping channel.

The first traveling vehicle and the second traveling vehicle may be symmetrically located on both sides of the power exchange channel, or may be asymmetrically located on both sides of the power exchange channel.

Considering that the charging compartment of the power swap station may be far away from the parking location of the electrical equipment, in order to further reduce the power swap time, in some embodiments, the method 200 may also include: controlling the installation while controlling the removal of the battery to be removed while driving. Driving the vehicle, transport the battery to be installed from the charging compartment to the installation location of the battery to be installed.

Optionally, the installation driving vehicle can be controlled to take out the battery to be installed from the charging compartment farthest from the electrical equipment, or the installation driving vehicle can be controlled to take out the battery to be installed from the charging compartment closest to the electrical equipment, or the installation can also be controlled. Take out any battery to be installed from all the charging compartments while driving, or you can determine which charging compartment to take the battery to be installed from based on the time required to remove the battery while driving.

Refer to Figures 3-6 for examples. In Figures 3 to 6, H is the battery replacement channel, A is the battery to be installed, and B is the battery to be removed. Along the direction from the tail to the head of the electrical equipment, the disassembly crane in Figures 3 and 4 is located on the left side of the electrical equipment, and the installation crane is located on the right side of the electrical equipment; the disassembly crane in Figures 5 and 6 is located on the right side of the electrical equipment. On the right side of the equipment, the installation carriage is located on the left side of the electrical equipment.

It can be seen from Figures 3 and 5 that when the disassembly driving vehicle removes the battery to be disassembled, the installation driving vehicle transports the battery to be installed from the charging compartment to the installation position of the battery to be installed. As can be seen from Figures 4 and 6, during the process of transporting the disassembled battery to be disassembled to the charging bin by the disassembly vehicle, the installation vehicle installs the battery to be installed on the electrical equipment.

In the embodiments of the present application, the size of the serial numbers of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application. .

Furthermore, as long as there is no conflict, the various embodiments described in this application and/or the technical features in each embodiment can be combined with each other arbitrarily, and the technical solution obtained after the combination should also fall within the protection scope of this application.
