DETAILED DESCRIPTION

[0034] The battery management cabinet and battery swap station provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other at will.

[0035] With the continuous development of new energy, electric vehicles are being widely promoted and used. When vehicle 1 needs to replace power, it needs to drive to a power replacement station 2 for replacement. In this embodiment, vehicle 1 is described as a light truck or a mini van, and the details are described below.

[0036] Figure 1 FIG. 2 is a schematic diagram of the structure of an embodiment of a battery swap station 2 of the present application. Figure 1As shown, the vehicle 1 includes a vehicle body 11, a battery exchange frame 12 and at least two replaceable battery packs 13. In this embodiment, the vehicle 1 is provided with two battery packs 13 as an example for illustration. The battery exchange frame 12 is arranged at the bottom of the vehicle body 11, and the two battery packs 13 are detachably hoisted at the bottom of the battery exchange frame 12, and are located on opposite sides of the vehicle 1. The battery exchange station 2 includes a parking platform 21, a battery exchange vehicle 22 and a battery management cabinet 23. The parking platform 21 is used to carry the vehicle 1, and the battery exchange frame 12 of the vehicle 1 is placed above the ground, which is conducive to the removal of the battery pack 13, thereby facilitating battery exchange. The battery exchange vehicle 22 is arranged close to one of the battery packs 13, and is located on the same side of the parking platform 21 as the battery management cabinet 23. The battery swap vehicle 22 moves between the battery management cabinet 23 and the parking platform 21, disassembles the battery pack 13 of the vehicle 1 and transports it to the battery management cabinet 23 for charging. For example, one of the battery packs 13 with insufficient power is disassembled from the bottom of the battery swap frame 12 and transported to the battery management cabinet 23 for charging. Then, the fully charged battery pack 13 is taken from the battery management cabinet 23, transported and assembled to the bottom of the battery swap frame 12, so as to realize the rapid battery swap of the vehicle 1 and solve the problem of insufficient battery life of the vehicle 1.

[0037] Specifically, a charger 131 is provided on the top of the battery pack 13. When the battery pack 13 is assembled on the battery exchange frame 12, it is plugged into the upper and lower electrical connectors of the vehicle accordingly. The two battery packs 13 are symmetrically arranged at the bottom of the battery exchange frame 12 in a direction perpendicular to the driving direction of the vehicle 1, and the two chargers 131 of the two battery packs 13 are both located on the side of the battery pack 13 facing the front of the vehicle 1. The distribution direction of the two battery packs 13 can be the width direction between the two wheels of the vehicle 1, and the width direction between the two wheels is perpendicular to the driving direction of the vehicle 1. The setting position of the charger 131 of the battery pack 13 is adapted to the setting position of the electrical connector of the vehicle. It should be noted that the electrical connector of the vehicle is arranged on the side of the battery exchange frame 12 facing the front of the vehicle 1, which is not shown in the figure.

[0038] The battery swap carrier 22 can be lifted up and down and moved. The battery swap carrier 22 includes a carrier body 221 and a tray 222 arranged on the carrier body 221, and the battery pack 13 is placed on the carrier body 221 through the tray 222. Since the volume and weight of the battery pack 13 are relatively large, the battery pack 13 is transported by the tray 222, and the transportation process is more stable and safe. When the battery pack 13 with insufficient power needs to be charged, the carrier body 221 lifts the tray 222 to remove the battery pack 13 located at the bottom of the battery swap frame 12, and the tray 222 and the battery pack 13 are transported to the battery management cabinet 23 together, and then placed in the battery management cabinet 23 for charging. After the battery pack 13 is fully charged, the tray 222 and the battery pack 13 are taken out from the battery management cabinet 23, and then the tray 222 and the fully charged battery pack 13 are transported to the bottom of the battery replacement frame 12 of the vehicle 1 through the carrier body 221, and the tray 222 is lifted to assemble the fully charged battery pack 13 at the bottom of the battery replacement frame 12, so as to realize the rapid battery replacement of the battery pack 13 in the chassis battery replacement method. The above battery replacement method is simple and efficient.

[0039] During the above-mentioned battery replacement process, the battery management cabinet 23 is used to charge the battery packs 13 set on both sides. The structure inside the battery management cabinet 23 is compatible with the setting direction of the charger of the battery pack 13. When the battery replacement vehicle 22 removes the battery packs 13 set on both sides, they can be directly placed in the battery management cabinet 23 for charging, that is, there is no need to rotate the direction of the battery pack 13, which can reduce manual operations and improve the efficiency of battery replacement.

[0040] Figure 2 Shown is a structural schematic diagram of an embodiment of a battery management cabinet 23 of the present application. Figure 2 Shown is a structural schematic diagram of an embodiment of a battery management cabinet 23 of the present application. Figure 3 Shown Figure 2 The schematic diagram of the structure of the battery management cabinet 23 shown is a front view. Figure 4 Shown Figure 3 A cross-sectional view of the battery management cabinet 23 at line AA is shown. Figure 5 Shown Figure 2 A partial structural diagram of the charger 315 of the battery management cabinet 23 is shown. Figure 6 Shown Figure 2 The principle block diagram of the battery management cabinet 23 is shown.

[0041] like Figures 1 to 6As shown, the battery management cabinet 23 includes a charging device 31, a charging cabinet 32, a sensor module 33 and a connector module 34. The charging device 31 includes a charger 315 and a charging controller 316 electrically connected to the charger 315. The charging cabinet 32 ​​is arranged on at least one side of the charger 315. The number of charging cabinets 32 can be set to one or more. When the number of charging cabinets 32 is set to one, it is arranged on one side of the charger 315. When the number of charging cabinets 32 is set to two, they are symmetrically arranged on both sides of the charger 315. The charging cabinet 32 ​​includes at least one charging compartment 321, and a battery pack 13 can be placed in each charging compartment 321. The charging cabinet 32 ​​includes one or more charging compartments 321. When the charging cabinet 32 ​​includes multiple charging compartments 321, the multiple charging compartments 321 are arranged in a vertical direction and / or a horizontal direction, and multiple battery packs 13 can be placed. The number of charging compartments 321 can be specifically designed according to actual needs and is not limited. The charging controller 316 is disposed at the back of the charging cabinet 32 ​​and is electrically connected to the charger 315. The charging controller 316 is used to control the charger 315 to charge the battery pack 13.

[0042] The sensor module 33 is arranged in each charging compartment 321, and the sensor module 33 is electrically connected to the charging controller 316. The sensor module 33 detects whether the battery pack 13 is placed in the charging compartment 321, and outputs a corresponding electrical signal. The sensor module 33 may be one of a position sensor and a distance sensor, or may be other in-place sensors, without limitation. In this embodiment, the sensor module 33 may be a distance sensor, which is arranged on the inner side of the charging compartment 321. When the battery pack 13 is not placed in the charging compartment 321, the distance sensor detects a first distance of the charging compartment 321 in the width direction (for example, the direction in which the battery pack 13 enters and exits the charging compartment 321), and outputs a first electrical signal. When the battery pack 13 is placed in the charging compartment 321, the distance sensor detects a second distance of the charging compartment 321 in the width direction, and outputs a second electrical signal. Wherein, the first distance is greater than the second distance, and the output first electrical signal and the second electrical signal represent different contents. In some embodiments, the number of sensor modules 33 is set to at least two, and at least two sensor modules 33 are arranged symmetrically on the inner side of the charging compartment 321. In this embodiment, the number of sensor modules 33 is set to two. Since the volume of the battery pack 13 is relatively large, the two sensor modules 33 are symmetrically arranged to make the detection result more accurate and ensure that the battery pack 13 is placed in place.

[0043] Since the charger 131 of the battery pack 13 is located at the top, the connector module 34 is arranged at the top of each charging compartment 321. The connector module 34 is arranged in the position of each charging compartment 321, and is aligned with the charger 131 of the battery pack 13 placed in the charging compartment 321 in the up and down direction. The connector module 34 includes a driving member 341 and an electrical connector 342 electrically connected to the driving member 341. The driving member 341 is electrically connected to the charging controller 316, and the electrical connector 342 is electrically connected to the charger 315. When the charger 315 receives the electrical signal output by the sensor module 33 indicating that the battery pack 13 is placed in the charging compartment 321, the driving member 341 is controlled to move downward, and the electrical connector 342 is driven to dock with the charger 131 set at the top of the battery pack 13 up and down, so that the charger 315 is electrically connected to the battery pack 13, and the charger 315 is controlled to charge the battery pack 13. In this embodiment, the driving member 341 can be a driving motor, and the electrical connector 342 can be electrically connected to the plug, and is adapted to the structure of the charger 131 of the battery pack 13. The electrical connector 342 is connected to the output shaft of the driving motor by transmission, and is electrically connected to the charger 315. When the charging controller 316 receives the second electrical signal of the sensor module 33, it determines that the battery pack 13 is placed in the charging compartment 321, and then controls the driving motor, and the output shaft of the driving motor drives the electrical connector 342 to move from top to bottom, so that the electrical connector 342 and the charger 131 of the battery pack 13 are docked up and down, so that the charger 315 is docked with the charger 131 through the electrical connector 342, and is electrically connected to the battery pack 13, and then controls the charger 315 to charge the battery pack 13, and the charger 315 is electrically connected to the external power supply, and the external power supply can charge the battery pack 13 through the charger 315. In this way, the automatic charging of the battery pack 13 with the charger 131 on the top can be realized, reducing manual operations, and the charging method is fast and accurate, improving convenience and efficiency.

[0044] In some embodiments, when the battery pack 13 is fully charged, the charging controller 316 will issue a disconnection command to control the output shaft of the drive motor to drive the electrical connector 342 to move from bottom to top, so that the electrical connector 342 is separated from the charger 131 of the battery pack 13 up and down, so that the electrical connector 342 is disconnected from the battery pack 13. In some embodiments, when the charging controller 316 receives an electrical signal from the sensor module 33 indicating that the battery pack 13 is out of the compartment, and it is confirmed that the battery pack 13 is no longer in the charging compartment 321, the drive motor is controlled at this time so that the output shaft of the drive motor drives the electrical connector 342 to automatically fall. In some other embodiments, when the charging controller 316 receives an electrical signal from the sensor module 33 indicating that the battery pack 13 is out of the compartment, and it is confirmed that the battery pack 13 is no longer in the charging compartment 321, the drive motor can also be controlled so that the output shaft of the drive motor drives the electrical connector 342 to remain in the original position, which is not limited in this application.

[0045] In some embodiments, the charger 315 and the charging cabinet 32 ​​are integrated. The charger 315 and the charging cabinet 32 ​​are integrated to save space and reduce the space occupied by the equipment. The high integration simplifies the installation process, saving installation time and cost. The integrated charger 315 and the charging cabinet 32 ​​can be monitored and controlled through a unified management system, which can reduce connectors and interfaces, reduce failure points, and improve the reliability of the entire battery management cabinet 23. Moreover, charging and storage of batteries can be completed in the same battery management cabinet 23, which makes the operation simpler and more convenient, and improves the user's charging experience.

[0046] In some embodiments, the connector module 34 is disposed on a side of the charging compartment 321 close to the charger 315. Since the driving member 341 of the connector module 34 is electrically connected to the charging controller 316 through a wiring harness, and the electrical connector 342 is electrically connected to the charger 315 through a wiring harness, the connector module 34 is disposed on a side close to the charger 315, which can shorten the wiring harness and make the structure simple and compact.

[0047] In some embodiments, multiple charging compartments 321 are stacked in the height direction of the charging cabinet 32. With this arrangement, the charging compartments 321 can be expanded upward in the height direction of the charging cabinet 32 ​​more flexibly, which is conducive to increasing the number of charging compartments 321 and has strong expandability. Correspondingly, each charging compartment 321 is provided with a connector module 34. While expanding the charging compartments 321, the number of connector modules 34 is simultaneously increased, which is conducive to realizing automatic charging. Figure 2 and Figure 3 In the illustrated embodiment, the charging cabinet 32 ​​is provided with six charging compartments 321, of which three charging compartments 321 are located on the left side of the charger 315, and the remaining three charging compartments 321 are located on the right side of the charger 315. A connector module 34 is configured in each charging compartment 321 to realize the charging function. In some other embodiments, multiple charging compartments 321 can also be expanded in the horizontal direction. The specific expansion number can be designed according to actual needs and is not limited in this application.

[0048] In some embodiments, in the same charging cabinet 32, the connector modules 34 provided in each charging compartment 321 are all located on the same side of the multiple charging compartments 321. For example, in the charging cabinet 32 ​​located on the left side of the charger 315, the connector modules 34 in each charging compartment 321 are all located on the right side of the charging compartment 321, and the right side is the side closest to the charger 315. For another example, in the charging cabinet 32 ​​located on the right side of the charger 315, the connector modules 34 in each charging compartment 321 are all located on the left side of the charging compartment 321, and the left side is the side closest to the charger 315. The left and right directions mentioned above can be Figure 2 or Figure 3The left and right directions of the main viewing angle shown. In this way, multiple connector modules 34 are arranged on the same side, which is conducive to assembly or maintenance, reduces wiring harnesses, and makes the structure compact.

[0049] In some embodiments, the number of charging cabinets 32 is set to two, and the two charging cabinets 32 are arranged on opposite sides of the charger 315. The charger 315 is located in the middle of the two charging cabinets 32. In the charging cabinets 32 located on both sides, the multiple connector modules 34 arranged in the multiple charging compartments 321 are symmetrically arranged relative to the charger 315. In the charging cabinets 32 on both sides, the connector modules 34 in each charging compartment 321 are symmetrically arranged. The charger 315 is located in the middle of the two charging cabinets 32, and the charging compartments 321 are arranged symmetrically on both sides, which can more flexibly expand the number of charging compartments 321 upward, and has strong expansion flexibility.

[0050] exist Figure 2 and Figure 3 In the illustrated embodiment, the charging cabinet 32 ​​includes a first charging cabinet 32a and a second charging cabinet 32b, and the first charging cabinet 32a and the second charging cabinet 32b are arranged on opposite sides of the charger 315. The multiple connector modules 34 in the first charging cabinet 32a and the multiple connector modules 34 in the second charging cabinet 32b are symmetrically arranged relative to the charger 315. The arrangement direction of the connector modules 34 is adapted to the assembly direction of the charger 131 of the battery pack 13. When replacing the battery, the battery pack 13 does not need to be placed upside down, that is, the battery pack does not need to be reversed during the battery replacement process, which can reduce manual operations.

[0051] In some embodiments, the multiple connector modules 34 disposed in the multiple charging compartments 321 in the charging cabinets 32 on both sides are all located on the side of the charging compartment 321 close to the charger 315. In some embodiments, the multiple connector modules 34 in the first charging cabinet 32a and the multiple connector modules 34 in the second charging cabinet 32b are all located on the side of the charging compartment 321 close to the charger 315. Figure 2 and Figure 3As shown, the first charging cabinet 32a can be a charging cabinet 32 ​​located on the left side of the charger 315. The connector module 34 in the first charging cabinet 32a is arranged on the right side of the charging compartment 321. When it is necessary to charge the battery pack 13 located on the right side of the vehicle 1, the charger 131 of the battery pack 13 is located on the right side relative to the vehicle body 221, and the charger 131 of the battery pack 13 is located on the right side relative to the vehicle body 221. The battery pack 13 on the right side can be directly placed in the first charging cabinet 32a, and can be matched with the connector module 34 of the charging compartment 321 on the right side. In this way, there is no need to reverse the direction of the battery pack 13, reducing manual operation. Similarly, the second charging cabinet 32b can be a charging cabinet 32 ​​located on the right side of the charger 315. The connector module 34 in the second charging cabinet 32b is arranged on the left side of the charging compartment 321. When the battery pack 13 located on the left side of the vehicle 1 needs to be charged, the charger 131 of the battery pack 13 is located on the left side relative to the vehicle body 221, and the charger 131 of the battery pack 13 is located on the left side relative to the vehicle body 221. The battery pack 13 on the left side can be directly placed in the second charging cabinet 32b, and can be matched up and down with the connector module 34 on the left side of the charging compartment 321. In this way, there is no need to reverse the direction of the battery pack 13, thereby reducing manual operation.

[0052] In some other embodiments, in the charging cabinets 32 located on both sides, the multiple connector modules 34 arranged in the multiple charging compartments 321 are all located on the side of the charging compartment 321 away from the charger 315. For example, the first charging cabinet 32a can be a charging cabinet 32 ​​located on the left side of the charger 315. The connector module 34 in the first charging cabinet 32a is arranged on the left side of the charging compartment 321. When it is necessary to charge the battery pack 13 located on the left side of the vehicle 1, the charger 131 of the battery pack 13 is located on the left side relative to the vehicle body 221, and the charger 131 of the battery pack 13 is located on the left side relative to the vehicle body 221. The battery pack 13 on the left side can be directly placed in the first charging cabinet 32a, and can be matched with the connector module 34 on the left side of the charging compartment 321 up and down, so that there is no need to reverse the direction of the battery pack 13, reducing manual operation. Similarly, the second charging cabinet 32b can be a charging cabinet 32 ​​located on the right side of the charger 315. The connector module 34 in the second charging cabinet 32b is arranged on the right side of the charging compartment 321. When the battery pack 13 located on the right side of the vehicle 1 needs to be charged, the charger 131 of the battery pack 13 is located on the right side relative to the vehicle body 221, and the charger 131 of the battery pack 13 is located on the right side relative to the vehicle body 221. The battery pack 13 on the right side can be directly placed in the second charging cabinet 32b, and can be matched up and down with the connector module 34 on the right side of the charging compartment 321. In this way, there is no need to reverse the direction of the battery pack 13, thereby reducing manual operation.

[0053] In some embodiments, the charger 315 includes a housing 311, a charging main control module 312, and a plurality of indicator lights 313 and a display screen 314 provided on the surface of the housing 311, wherein the plurality of indicator lights 313 and the display screen 314 are electrically connected to the charging main control module 312.

Each support portion 323 is arranged in the horizontal direction, and multiple support portions 323 are arranged at intervals along the height direction of the charging cabinet 32. Multiple support portions 323 divide the space in the cabinet 322 and form multiple charging compartments 321. The height direction of the charging cabinet 32 ​​may be a vertical direction. By arranging multiple support portions 323 in the cabinet 322, different numbers of charging compartments 321 are formed to place different numbers of battery packs 13. The support portion 323 plays a role in supporting the battery pack 13. In some embodiments, the support portion 323 is a hollow structure, and the support portion 323 includes multiple support members 324 located in a horizontal plane and intersectingly arranged. The support portion 323 is arranged as a hollow structure, so that the open area in the cabinet 322 is large, and the contact area between the support portion 323 and the battery pack 13 is small, which makes it easier to dissipate heat and reduces the risk of thermal runaway of the battery. In this embodiment, a plurality of supporting legs 328 are provided at the bottom of the charging cabinet 32, and the cabinet body 322 is supported by the plurality of supporting legs 328, with a gap between the cabinet body 322 and the ground. The support portion 323 provided at the bottom of the charging cabinet 32 ​​is also a hollow structure, which is conducive to heat dissipation and cooling, and improves safety. The support portion 323 may be made of square steel pipe material. The square steel pipe material has high hardness and strength, and strong bearing capacity. The rated load of the entire cabinet body 322 can reach at least two tons without deformation. In some other embodiments, the support portion 323 may be a support member made of other materials, which is not limited in this application.

[0056] In some embodiments, the support member 324 is provided with a roller 325. The roller 325 is located at the bottom of each charging compartment 321. When the battery pack 13 is placed in the charging compartment 321, the roller 325 rolls and abuts against the bottom surface of the battery pack 13. The support member 324 may be provided with a plurality of rollers 325, and the plurality of rollers 325 are spaced apart on the support member 324. Since the weight and volume of the battery pack 13 are relatively large, by providing a plurality of rollers 325 at the bottom of the charging compartment 321 to reduce the friction between the bottom of the battery pack 13 and the support member 324, the resistance of the battery pack 13 when entering and exiting the charging compartment 321 is reduced, which is conducive to the battery pack 13 being easily pushed into the charging compartment 321, and can reduce the difficulty of the battery pack 13 entering and exiting the charging compartment 321, which is labor-saving and convenient. Furthermore, by providing the roller 325 , the positioning accuracy of the battery pack 13 can be improved, so that the battery pack 13 can be pushed into the charging compartment 321 , thereby improving the connection success rate between the charger 131 of the battery pack 13 and the electrical connector 342 .

[0057] In some embodiments, the support member 324 is provided with a guide wheel 326. The guide wheel 326 is located on the side of each charging compartment 321. When the battery pack 13 is placed in the charging compartment 321, the guide wheel 326 rolls and abuts against the side of the battery pack 13. The support member 324 may be provided with a plurality of guide wheels 326, and a plurality of rollers 325 are spaced apart on the support member 324. Since the weight and volume of the battery pack 13 are relatively large, a plurality of guide wheels 326 are provided on the side of the charging compartment 321 to assist the battery pack 13 to be smoothly pushed into the charging compartment 321, and the horizontal position of the battery pack 13 can be adjusted, thereby reducing the difficulty of the battery pack 13 entering and exiting the charging compartment 321, making the battery replacement method labor-saving and quick.

[0058] In some embodiments, the support member 324 is provided with a locking member 327, and the locking member 327 is located at the opening of each charging compartment 321. One or more locking members 327 may be provided. When the battery pack 13 and the tray 222 are placed in the charging compartment 321, the battery pack 13 and the tray 222 are locked in the charging compartment 321 by the locking member 327, so that the charging stability is better. When the battery pack 13 is fully charged and needs to be taken out of the charging compartment 321, the locking member 327 is operated to unlock the battery pack 13 and the tray 222 from the charging compartment 321, which is convenient for taking.
