Description

Technical Field

[0001] The present application relates to the technical field of battery replacement for electric vehicles, and in particular to an integrated charging, replacement and storage device and equipment. Background Art

[0002] With the widespread use of electric vehicles, charging stations and battery swap stations are becoming increasingly common and rapidly being built. Charging stations can recharge electric vehicles, while battery swap stations can replace batteries in electric vehicles. However, electric vehicles that require both battery swapping and charging must first be swapped at a battery swap station and then recharged at a charging station. This process is cumbersome and can lead to slow charging times and high electricity costs during peak hours. Summary of the Invention

[0003] In view of this, it is necessary to provide an integrated charging, swapping and storage device and equipment to solve the technical problems of the existing complicated charging and swapping process and slow charging during peak power consumption.

[0004] The present application proposes an integrated charging, swapping and storage device, including a battery swap unit, an energy storage unit and a charging unit. The battery swap unit is used to replace and accommodate the first battery of a battery swap vehicle; the energy storage unit is electrically connected to the battery swap unit, the power grid and the user, and is used to store the electric energy input from the power grid to charge the first battery accommodated in the battery swap unit, and to supply power to the power grid and / or the user; the charging unit is electrically connected to the energy storage unit and the power grid, and is used to charge the battery swap vehicle using the electric energy stored in the energy storage unit or the electric energy of the power grid.

[0005] In some embodiments, the energy storage unit includes a scrapped battery, which is a battery that meets the scrapping standard of the battery-swap vehicle but is still able to store electricity.

[0008] In some embodiments, the charging unit, the energy storage unit and the battery replacement unit are stacked in sequence.

[0009] In some embodiments, the battery exchange unit includes at least two battery exchange components, which are used to accommodate a first battery removed from a battery exchange vehicle and a fully charged second battery respectively. Each of the battery exchange components includes a battery exchange rack, a first locking member and a second locking member. The battery exchange rack includes a battery exchange compartment for accommodating the first battery or the second battery. The first locking member and the second locking member are both provided on the battery exchange rack and can be extended into the battery exchange compartment to lock the first battery or the second battery in a first direction or a second direction.

[0010] This application also proposes a charging, swapping and storage integrated device, comprising:

[0011] An integrated charging, swapping and storage device, comprising a battery swapping unit, an energy storage unit and a charging unit, wherein the battery swapping unit is used to replace and accommodate the first battery of a battery swapping vehicle; the energy storage unit is electrically connected to the battery swapping unit, the power grid and the user, and is used to store electric energy input from the power grid to charge the first battery accommodated in the battery swapping unit, and to supply power to the power grid and / or the user; the charging unit is electrically connected to the energy storage unit and the power grid, and is used to charge the battery swapping vehicle using the electric energy stored in the energy storage unit or the electric energy of the power grid; and

[0013] In some embodiments, there are multiple integrated charging, swapping and storage devices, and they are arranged in different areas. The charging units of the multiple integrated charging, swapping and storage devices use the electric energy stored in the energy storage units to supply power to the power grid and / or users.

[0014] In some embodiments, at least one battery-exchange potential is provided on the peripheral side of the integrated charging, swapping and storage device for performing battery exchange and / or charging for a plurality of the battery-exchange vehicles.

[0015] In some embodiments, the battery-swapping vehicle has a signal receiver, and the pick-and-place device has a signal generator adapted to the signal receiver. The signal generator can trigger the signal receiver when the pick-and-place device moves under the first battery of the battery-swapping vehicle, so that the battery-swapping vehicle unlocks the first battery and enables the pick-and-place device to remove the first battery.

[0080] This application also proposes a charging, swapping and storage integrated device, comprising:

[0084] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0085] See Figure 1 The first embodiment of the present application proposes an integrated charging, swapping and storage device 100, including a battery swap unit 10, an energy storage unit 20 and a charging unit 30.

[0086] The battery exchange unit 10 is used to replace and accommodate the first battery 6 of the battery exchange vehicle 4; the energy storage unit 20 is electrically connected to the battery exchange unit 10, the power grid 7 and the user, and is used to store the electric energy input from the power grid 7 to charge the first battery 6 accommodated in the battery exchange unit 10 and to supply power to the power grid 7 and / or the user; the charging unit 30 is electrically connected to the energy storage unit 20 and the power grid 7, and is used to charge the battery exchange vehicle 4 using the electric energy stored in the energy storage unit 20 or the electric energy of the power grid 7.

[0087] Among them, the battery swap unit 10, the energy storage unit 20 and the charging unit 30 are an integrated structure, and the three can be stacked in sequence according to the required number, thereby reducing the overall occupied area of the battery swap unit 10, the energy storage unit 20 and the charging unit 30, and the layout is relatively compact, and the battery swap vehicle 4 can perform battery swap and charging operations in one parking space; for example Figure 2 As shown, there is one battery swap unit 10, which is located at the bottom; there is one charging unit 30, which is located at the top; there are two energy storage units 20, which are stacked between the charging unit 30 and the battery swap unit 10. It is understood that in other embodiments, there is one battery swap unit 10, which is located at the bottom; there is one charging unit 30, which is located at the top; and there is one energy storage unit 20, which is arranged between the charging unit 30 and the battery swap unit 10.

[0088] See Figure 3 The battery exchange unit 10 in the first embodiment includes three battery exchange components 11, a base 12, a charger 13 and a protective cover 14.

[0089] The three battery-swapping assemblies 11 are arranged side by side in a straight line, and are used to accommodate the first battery 6 removed from the battery-swapping vehicle 4 and the fully charged second battery 1. The first battery 6 can be a low-power battery or a dead battery; two of the battery-swapping assemblies 11 accommodate the second battery 1, and one of the battery-swapping assemblies 11 is used to accommodate the first battery 6 and can charge the first battery 6. Figure 3 The battery exchange compartment 1111 of one of the battery exchange components 11 is empty.

[0090] Each battery exchange assembly 11 includes a battery exchange frame 111, a first locking member 112 and a second locking member 113. The battery exchange frame 111 is roughly a frame-shaped structure. The battery exchange frame 111 includes a battery exchange compartment 1111 for accommodating the first battery 6 or the second battery 1. The length or width of the battery exchange compartment 1111 is larger than the first battery 6 or the second battery 1. The first locking member 112 is arranged in the battery exchange frame 111 and can be extended into the battery exchange compartment 1111 in the first direction to lock the first battery 6 or the second battery 1 in the first direction. The second locking member 113 is arranged in the battery exchange frame 111 and can be extended into the battery exchange compartment 1111 in the second direction to lock the first battery 6 or the second battery 1 in the second direction. The first locking member 112 and the second locking member 113 cooperate with each other to lock the first battery 6 or the second battery 1 in the first direction or the second direction. In this embodiment, the first direction is defined as the X-axis direction, and the second direction is defined as the Y-axis direction.

[0091] See Figure 4 Taking the second battery 1 as an example, the long side dimension of the battery swap compartment 1111 is larger than the long side dimension of the second battery 1, and the short side dimension of the battery swap compartment 1111 is equal to the short side dimension of the second battery 1. At this time, the short side of the second battery 1 can be locked by extending the second locking piece 113 into the battery swap compartment 1111.

[0092] See Figure 5 The long side of the battery swap compartment 1111 is equal to the long side of the second battery 1, and the short side of the battery swap compartment 1111 is larger than the short side of the second battery 1. At this time, the long side of the second battery 1 can be locked by extending the first locking piece 112 into the battery swap compartment 1111.

[0093] See Figure 6 Two first locking members 112 are arranged at intervals on each long side of the battery swapping rack 111, and the first locking members 112 on the two long sides of the battery swapping rack 111 are arranged opposite to each other; two second locking members 113 are arranged at intervals on each short side of the battery swapping rack 111, and the second locking members 113 on the two short sides of the battery swapping rack 111 are arranged opposite to each other.

[0094] The first locking member 112 includes a first telescopic rod 1121 and a first driving member 1122. The first telescopic rod 1121 is provided on the long side of the battery exchange rack 111. A first hole 1112 is provided on the long side of the battery exchange rack 111 corresponding to the position of the first telescopic rod 1121. The first telescopic rod 1121 can move in the first direction through the first hole 1112 and extend into the battery exchange compartment 1111 to be inserted into the locking hole 3 provided in the first direction of the first battery 6 or the second battery 1, thereby locking the first battery 6 or the second battery 1 in the first direction. The first driving member 1122 is provided on the long side of the battery exchange rack 111 and is connected to the first telescopic rod 1121 to drive the first telescopic rod 1121 to move along the first direction. In this embodiment, the first driving member 1122 is a cylinder.

[0095] The second locking member 113 includes a second telescopic rod 1131 and a second driving member 1132. The second telescopic rod 1131 is provided on the short side of the battery exchange rack 111. A second hole 1113 is provided on the short side of the battery exchange rack 111 corresponding to the position of the second telescopic rod 1131. The second telescopic rod 1131 can move in the second direction through the second hole 1113 and extend into the battery exchange compartment 1111 to be inserted into the locking hole 3 provided in the second direction for the first battery 6 or the second battery 1, thereby locking the first battery 6 or the second battery 1 in the second direction. The second driving member 1132 is connected to the second telescopic rod 1131 to drive the second telescopic rod 1131 to move in the second direction. In this embodiment, the second driving member 1132 is a cylinder.

[0096] In some embodiments, the battery swap assembly 11 further includes a plurality of floating suspensions 114, the number of which is four and which are arranged at the four corners of the upper surface of the battery swap frame 111. Each floating suspension 114 is an independent suspension, one end of which is connected to the battery swap frame 111, and the other end of which is connected to the base 12, so that the battery swap frame 111 floats along the direction of gravity during battery swapping. In this embodiment, the direction of gravity is defined as the Z-axis direction.

[0097] During use, when the first battery 6 is installed in the battery swap compartment 1111, the first driving member 1122 on the long side of the battery swap rack 111 drives the first telescopic rod 1121 to move in the first direction and inserts it into the locking hole 3 set in the first direction of the first battery 6, thereby locking the first battery 6 in the first direction; or the second driving member 1132 on the short side of the battery swap rack 111 drives the second telescopic rod 1131 to move in the second direction and inserts it into the locking hole 3 set in the second direction of the first battery 6, thereby locking the first battery 6 in the second direction.

[0098] Please continue to see Figure 3 The base 12 is roughly rectangular and is used to carry the battery exchange component 11. The position of the base 12 corresponding to the battery exchange component 11 is hollowed out to form a battery exchange space 121, which is used to move the pick-up and placement device 300 from the outside to the battery exchange space 121 and reach the bottom of the battery exchange component 11 to lift the first battery 6 to the battery exchange compartment 1111 where the first battery 6 and the second battery 1 are not placed, and remove the second battery 1 from the battery exchange compartment 1111 and move it to the battery exchange vehicle 4 for battery exchange.

[0099] The charger 13 is provided on the base 12 and is provided corresponding to the battery swap assembly 11, that is, the number of chargers 13 is equal to the number of battery swap assemblies 11. The charger 13 includes a first connector 131, which is used to be inserted into the second connector 2 of the first battery 6 when the first battery 6 is lifted into the battery swap compartment 1111 to charge the first battery 6. In some embodiments, the first connector 131 is a charging plug and the second connector 2 is a charging socket. After the two are plugged in, the charger 13 can charge the first battery 6. In some embodiments, the second connector 2 is a charging socket and the second connector 2 is a charging plug. After the two are plugged in, the charger 13 can also charge the first battery 6.

[0100] The protective cover 14 is arranged on the base 12, and the cover is arranged on the outside of the charger 13 and the battery exchange component 11, thereby forming protection for the charger 13 and the battery exchange component 11, preventing foreign objects or water from entering the charger 13 and the battery exchange component 11, and thus affecting the use of the charger 13 and the battery exchange component 11.

[0101] In some embodiments, the battery swap unit 10 further includes a visual recognition module 15, which is provided on the protective cover 14 and is used to obtain visual information of a first preset position to determine whether the battery swap vehicle 4 has moved to the first preset position, wherein the first preset position is the parking position of the battery swap vehicle 4, i.e., the battery swap position. The battery swap position is fixed, and the battery swap vehicle 4 performs a battery swap operation at this position. When the visual recognition module 15 senses that the battery swap vehicle 4 has reached the parking position, the pick-up and placement device 300 starts to move toward the battery swap vehicle 4, removes the first battery 6 of the battery swap vehicle 4, and lifts the second battery 1 to the battery swap vehicle 4. The visual recognition module 15 includes but is not limited to a camera and a CCD camera.

[0102] See Figure 7 The structure of the battery replacement unit 10 in the second embodiment is substantially the same as that in the first embodiment, except that:

[0103] The shield 14 in the second embodiment is substantially in the shape of a cuboid, completely covering the upper surface of the base 12 , thereby forming a cuboid structure with the base 12 as a whole; whereas the shield 14 in the first embodiment only covers a portion of the base 12 .

[0104] There are four battery-changing components 11 in the second embodiment, and they are arranged in a field shape, wherein three battery-changing components 11 accommodate the second battery 1, and one battery-changing component 11 is used to accommodate the first battery 6 and charge the first battery 6. Figure 7 The battery swap compartment 1111 of one of the battery swap components 11 is empty. Correspondingly, the number of chargers 13 is also four, and they are arranged in a field shape, and are respectively arranged above the four battery swap components 11.

[0105] Please continue to see Figure 1 In some embodiments, the integrated charging, swapping and storage device 100 further includes a distribution box 40, a bidirectional AC / DC 50, a splitter 60 and a DC-DC 70.

[0106] The distribution box 40 is electrically connected to the power grid 7 and is used to control the power output of the power grid 7, which can be controlled manually or automatically by the background. The distribution box 40 is also equipped with fire-fighting equipment, such as a fire extinguisher, to deal with fire hazards. Since there are multiple transformers in a city and the utilization rate of transformers is not high, that is, most transformers are not used, that is, they are redundant. In this embodiment, the charging, swapping and storage integrated device 100 can be used near the redundant transformers, eliminating the need to build new transformers and saving costs.

[0107] In some embodiments, the distribution box 40 is also electrically connected to the user through the splitter 60, thereby transmitting the electric energy of the power grid 7 to different users. It can be understood that the user is a merchant, community or factory near the charging, swapping and storage integrated device 100.

[0108] In some embodiments, the bidirectional AC / DC 50 is electrically connected to the distribution box 40 and the battery exchange unit 10 respectively, and is used to convert the AC power input from the power grid 7 into DC power and transmit it to the battery exchange unit 10, and to convert the DC power input from the battery exchange unit 10 into AC power.

[0109] When it is necessary to charge the first battery 6 in the battery exchange unit 10, the switch device of the distribution box 40 is turned on, and the AC power of the power grid 7 is transmitted to the bidirectional AC / DC 50. The bidirectional AC / DC 50 converts the AC power into DC power and transmits it to the battery exchange unit 10, thereby charging the first battery 6 accommodated therein.

[0110] During peak electricity consumption, if the second battery 1 of the battery exchange unit 10 has surplus electric energy, that is, a part of the second battery 1 of the battery exchange unit 10 can meet the battery exchange needs, at this time, the DC power of the other part of the second battery 1 can be converted into AC power through the bidirectional AC / DC 50 and transmitted to the power grid 7 or the user through the distribution box 40, and the first battery 6 housed in the battery exchange unit 10 can be charged by the electric energy of the power grid 7 during low electricity consumption. In this way, commercial needs can be met and the use cost of the integrated charging, swapping and storage device 100 is reduced.

[0111] It should be noted that the bidirectional AC / DC 50 is formed by a combination of an AC-DC converter and a DC-AC converter. The function of the AC-DC converter is to convert alternating current into direct current, and the function of the DC-AC converter is to convert direct current into alternating current.

[0112] The distribution box 40 is a low-voltage distribution box assembled in accordance with electrical wiring requirements, combining switchgear, measuring instruments, protective devices, and auxiliary equipment within an enclosed or semi-enclosed metal cabinet or on a screen. During normal operation, manual or automatic switches connect and disconnect the circuit. In the event of a fault or abnormal operation, protective devices disconnect the circuit or generate an alarm. Measuring instruments display various operating parameters, allow adjustment of certain electrical parameters, and provide prompts or signals indicating deviations from normal operating conditions.

[0113] In some embodiments, the energy storage unit 20 is electrically connected to the bidirectional AC / DC 50 and the DC-DC 70, respectively, and the DC-DC 70 is electrically connected to the battery exchange unit 10 and the charging unit 30, respectively, for storing the electric energy input from the power grid 7, and charging the battery exchange vehicle 4 through the charging unit 30 with the stored electric energy and transmitting it to the battery exchange unit 10 to charge the first battery 6 accommodated after the battery exchange.

[0114] When the energy storage unit 20 needs to store energy, the switch device of the distribution box 40 is turned on, and the AC power of the power grid 7 is transmitted to the bidirectional AC / DC 50. The bidirectional AC / DC 50 converts the AC power into DC power and then transmits it to the energy storage unit 20 for energy storage. The energy storage unit 20 preferentially stores the electric energy input from the power grid 7 during the off-peak period because the electricity price at this time is lower than the electricity price during the peak period. The stored electric energy can be used to charge the battery-swapping vehicle 4 through the charging unit 30, to charge the first battery 6 accommodated in the battery-swapping unit 10 after the battery is swapped, and to supply power to the power grid and / or users during the peak period.

[0115] Among them, since the voltage input to the energy storage unit 20, the voltage for charging the battery-swapping vehicle 4, and the voltage for charging the first battery 6 are different, the voltage input to the energy storage unit 20 needs to be converted into different voltages to meet different charging needs. In this embodiment, DC-DC70 can convert the voltage output from the energy storage unit 20 into the voltage required for charging the battery-swapping vehicle 4 and the voltage required for charging the first battery 6, thereby charging the battery-swapping vehicle 4 and charging the first battery 6.

[0116] In some embodiments, during peak electricity consumption or industrial power rationing, if there is surplus electricity in the energy storage unit 20, the energy storage unit 20 can convert the stored electricity into alternating current through the bidirectional AC / DC 50 and transmit it to the power grid 7 or users through the distribution box 40, thereby obtaining commercial benefits and reducing the operating costs of the integrated charging, swapping and storage device 100.

[0117] In some embodiments, the energy storage unit 20 includes multiple scrapped batteries, which are batteries that meet the scrapping standards of the battery-swap vehicle 4 but can still store electricity. For example, a scrapped battery can only reach 50% of the power of a new battery after being fully charged. In this way, the scrapped batteries of the battery-swap vehicle 4 can be reused.

[0118] In some embodiments, the charging unit 30 includes a charging gun 32, which is used to charge the battery-swapping vehicle 4 using the electric energy stored in the energy storage unit 20 and the electric energy of the power grid 7. Specifically, it can be set according to the principle of minimizing the charging cost. For example, during peak hours of electricity consumption, the electricity price is high. At this time, the electric energy stored in the energy storage unit 20 can be used to charge the battery-swapping vehicle 4; for example, during low electricity consumption, the electricity price is low. At this time, the electric energy of the power grid 7 can be used to charge the battery-swapping vehicle 4. In this embodiment, the number of charging guns 32 is two. It can be understood that in other embodiments, the number of charging guns 32 can be three, and three battery-swapping vehicles 4 can be charged simultaneously.

[0119] It will be understood by those skilled in the art that the peak and valley power consumption of the power grid can be set according to time periods. For example, the peak power consumption period is from 9 a.m. to 6 p.m., and the valley power consumption period is from 6 p.m. to 9 a.m. the next day. In some embodiments, the charging, swapping and storage integrated device 100 further includes a control center (not shown) connected to the distribution box 40. The peak and valley power consumption of the power grid can be determined by the control center monitoring the voltage changes of the power grid 7. Specifically, a threshold is set for the voltage of the power grid 7. When the voltage of the power grid 7 is lower than the threshold, it is a peak power consumption period, and when the voltage of the power grid 7 is higher than the threshold, it is a valley power consumption period.

[0120] See Figure 8 The second embodiment of the present application proposes an integrated charging, swapping and storage device 200, including at least one integrated charging, swapping and storage device 100 and at least one picking and placing device 300, the picking and placing device 300 is used to move back and forth between the battery swapping vehicle 4 and the battery swapping unit 10, to remove the first battery 6 from the battery swapping vehicle 4 and lift the first battery 6 to the battery swapping compartment 1111 of a battery swapping component 11, and to remove the second battery 1 from the battery swapping compartment 1111 of a battery swapping component 11 and lift the second battery 1 to install it on the battery swapping vehicle 4.

[0121] In some embodiments, there are multiple integrated charging, swapping and storage devices 100, and they are arranged in different areas. The electric energy stored in the energy storage units of the multiple integrated charging, swapping and storage devices 100 supplies power to the power grid and / or users.

[0122] Among them, multiple integrated charging, swapping and storage devices 100 are distributed in different areas in a point-like manner. During peak power consumption or industrial power restrictions, the power grid and / or users can be powered by the electric energy stored in the energy storage units of multiple integrated charging, swapping and storage devices 100. In some embodiments, the power grid 7 and / or users can also be powered by the electric energy stored in the battery swapping units 10 of multiple integrated charging, swapping and storage devices 100.

[0123] In some embodiments, at least one battery exchange station is provided around the charging, swapping and storage integrated device 100, and each battery exchange station is used to park a battery swapping vehicle 4 for battery swapping and / or charging multiple battery swapping vehicles 4. Figure 9There are 4 battery-swapping potentials, which are located around the integrated charging, swapping and storage device 100. The integrated charging, swapping and storage device 100 can swap batteries and / or charge the four battery-swapping vehicles 4 respectively.

[0124] See Figure 10 The pick-and-place device 300 further includes a moving base 321 , a driving module 322 , a navigation module 323 , a lifting mechanism 324 and a positioning module 325 .

[0125] The positioning module 325 is provided on the movable base 321 and is used to obtain positioning information after the battery-swapping vehicle 4 moves to the first preset position, so as to move the pick-up and placement device 300 to the second preset position below the battery-swapping vehicle 4, wherein the first preset position is the battery replacement position, and the second preset position is the position below the first battery to be replaced of the battery-swapping vehicle 4. The positioning module 325 includes but is not limited to a laser sensor.

[0126] The bottom of the movable base 321 is provided with four movable wheels 3211 to move the movable base 321. In this embodiment, the movable wheels 3211 are Mecanum wheels.

[0127] The drive module 322 is disposed on the movable base 321 and is connected to the movable wheels 3211, respectively, for driving the movable wheels 3211 to rotate, thereby moving the movable base 321 in the first direction and / or the second direction. In this embodiment, the drive module 322 comprises two motors, one motor being connected to each of the two movable wheels 3211, thereby simultaneously driving the two movable wheels 3211 to move.

[0128] The navigation module 323 is arranged on the mobile seat 321 and is used to set the travel path between the second preset position and the battery exchange unit 10 to navigate the movement of the mobile seat 321, where the second preset position is the lower position corresponding to the first battery 6 to be replaced of the battery exchange vehicle 4.

[0129] The lifting mechanism 324 is provided on the movable base 321. The lifting mechanism 324 includes a driving member 3241 and a lifting member 3242. The middle portion of the movable base 321 has an accommodating cavity 3212. The lifting member 3242 is generally plate-shaped and is disposed within the accommodating cavity 3212. There are four driving members 3241, which are disposed on opposite sides of the lifting member 3242. Two driving members 3241 are connected to one side of each lifting member 3242. When the four driving members 3241 are activated simultaneously, the lifting member 3242 can be driven to rise or fall, thereby carrying the first battery 6 of the battery-swapping vehicle 4 and lifting the first battery 6 to the battery-swapping compartment 1111, and carrying the second battery 1 of the battery-swapping compartment 1111 and lifting the second battery 1 to the battery-swapping vehicle 4. In this embodiment, after the lifting member 3242 carries the first battery 6, the driving member 3241 drives the lifting member 3242 to fall, thereby accommodating the first battery 6 within the accommodating cavity 3212.

[0130] See Figure 11 In some embodiments, the battery-swap vehicle has a signal receiver, and the picking and placing device has a signal generator adapted to the signal receiver. The signal generator can trigger the signal receiver when the picking and placing device moves to a second preset position under the first battery of the battery-swap vehicle, so that the battery-swap vehicle unlocks the first battery and enables the picking and placing device 300 to remove the first battery.

[0131] The battery replacement process of the integrated charging, swapping and storage device 200 is as follows:

[0132] When the battery-swapping vehicle 4 moves to the swapping position, the positioning module 325 obtains the position information of the first battery 6 to be replaced on the battery-swapping vehicle 4; then the navigation module 323 sets the travel path, and then the driving module 322 drives the moving seat 321 to move along the travel path to the bottom of the first battery 6 to be replaced on the battery-swapping vehicle 4, and starts the signal generator 326 of the pick-and-place device 300, and the adapted signal receiver 5 on the battery-swapping vehicle 4 is triggered and unlocks the first battery 6;

[0133] The driving member 3241 drives the lifting member 3242 to rise and carry the unlocked first battery 6 of the battery-swapping vehicle 4, and then the driving member 3241 drives the lifting member 3242 to descend, so that the first battery 6 is accommodated in the accommodating cavity 3212; finally, the driving module 322 drives the moving seat 321 to continue to move along the travel path until it moves to the bottom of the battery-swapping compartment 1111 of the battery-swapping unit 10 that does not accommodate the first battery 6 and the second battery 1;

[0134] The driving member 3241 drives the lifting member 3242 to rise and lift the carried first battery 6 to the battery swap compartment 1111, and the first driving member 1122 on the long side of the battery swap rack 111 drives the first telescopic rod 1121 to move in the first direction and insert it into the locking hole 3 set in the first direction of the first battery 6, thereby locking the first battery 6 in the first direction; or the second driving member 1132 on the short side of the battery swap rack 111 drives the second telescopic rod 1131 to move in the second direction and insert it into the locking hole 3 set in the second direction of the first battery 6, thereby locking the first battery 6 in the second direction; after the lifting is completed, the first connector 131 of the charger 13 can be inserted into the second connector 2 of the first battery 6 to charge the first battery 6;

[0135] The driving module 322 drives the movable seat 321 to the bottom of the battery exchange compartment 1111 which accommodates the second battery 1. After one of the first locking member 112 and the second locking member 113 unlocks the second battery 1, the lifting member 3242 carries the second battery 1, and then the driving member 3241 drives the lifting member 3242 to descend, so that the second battery 1 is accommodated in the accommodating cavity 3212; then the driving module 322 drives the movable seat 321 to continue to move along the travel path until it moves to the bottom of the first battery 6 to be replaced in the battery exchange vehicle 4; thereafter, the driving member 3241 drives the lifting member 3242 to rise and lift the carried second battery 1 to the battery exchange vehicle 4, and drives the lifting member 3242 to descend to the initial position, and finally the driving module 322 drives the movable seat 321 to continue to move along the travel path until it moves to the initial position.

[0136] In some embodiments, there are multiple first batteries 6 that need to be replaced. At this time, after replacing the first first battery 6, the driving module 322 drives the movable seat 321 to move to the bottom of the second first battery 6 to replace the second first battery 6. The process of replacing the second battery 1 is the same as the process of replacing the first battery, and will not be repeated here.

[0137] The battery swapping process of the integrated charging, swapping and storage device 200 is as follows: when the battery swapping vehicle 4 reaches the battery swapping point during peak power consumption, the charging gun 32 is inserted into the battery swapping vehicle 4, and the electric energy stored in the energy storage unit 20 is used to charge the battery swapping vehicle 4; when the battery swapping vehicle 4 reaches the battery swapping point during low power consumption, the charging gun 32 is inserted into the battery swapping vehicle, and the battery swapping vehicle 4 is charged using the power grid.

[0138] In the above-mentioned integrated charging, swapping and storage device 200, since the battery swapping unit 10, the energy storage unit 20 and the charging unit 30 are arranged in an integrated manner, the battery swapping vehicle 4 can move to a swapping point to swap the battery in the battery swapping unit 10 and charge the charging unit 30, and the charging and swapping efficiency is relatively high; and the energy storage unit 20 can store the electric energy input from the power grid 7, and can charge the first battery 6 housed in the battery swapping unit 10, and supply power to the power grid 7 and / or users during peak power consumption or industrial power restrictions, which has good commercial benefits and can increase the revenue of the integrated charging, swapping and storage device 100.

[0139] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
