Description

[0001] This application claims priority to Chinese invention patent application CN2022101731390, filed on February 24, 2022. The entire contents of the aforementioned Chinese patent application are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of electric motor vehicles, and in particular to a multifunctional battery swapping station and its battery swapping method. Background Technology

[0003] Currently, electric non-motorized vehicles have brought great convenience to people's short-distance travel. However, when the vehicle is out of power, it often takes several hours to charge. Moreover, it is difficult to standardize the charging method, which can easily lead to safety accidents during charging. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of long charging time and low safety of electric non-motorized vehicles in the prior art, and to provide a multifunctional battery swapping station and its battery swapping method.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution: a multi-functional battery swapping station for swapping batteries of electric motor vehicles, the battery swapping station comprising a parking platform for parking electric motor vehicles for battery swapping, a first battery compartment disposed on at least one side of the parking platform, and battery swapping equipment for removing or installing batteries of the electric motor vehicles, wherein the first battery compartment stores a first battery pack for swapping batteries of electric motor vehicles, characterized in that the multi-functional battery swapping station further comprises a second battery compartment electrically connected to the first battery compartment, the second battery compartment storing a second battery pack for swapping batteries of electric non-motorized vehicles.

[0006] In this solution, by integrating the second battery compartment for swapping batteries for electric non-motorized vehicles with the first battery compartment, the battery swapping station can be used for both electric motorized vehicles and electric non-motorized vehicles, thus increasing the functionality of the battery swapping station. At the same time, since the second and first battery compartments share the same power supply equipment for the same battery swapping station, the construction cost and land area for swapping batteries for non-motorized vehicles can be saved.

[0007] Preferably, the first battery compartment is disposed on any side of the parking platform along the direction of travel of the electric motor vehicle, the first battery compartment includes a first battery rack having a plurality of first compartments arranged in a vertical direction, and the second battery compartment is disposed close to the first battery rack and within the coverage area of ​​the first battery compartment.

[0008] In this design, the second battery compartment is positioned close to the first battery rack, allowing the first rack to provide support and increase the overall strength of the second battery compartment, resulting in a more compact structure. Furthermore, placing the second battery compartment in an area opposite the first battery compartment makes efficient use of the existing space within the battery swapping station, resulting in a more rational and aesthetically pleasing overall layout.

[0009] Preferably, the first battery compartment has a recessed area for storing the second battery compartment, and any side wall of the recessed area has a through hole for passing through electrical connection lines.

[0010] In this design, the second battery compartment is placed within the planar area of ​​the first battery compartment, making the structure of the second and first battery compartments more compact and aesthetically pleasing. The through holes for the electrical connection lines are located on the side wall of the housing area, shortening the distance of the electrical connection lines and reducing the difficulty of wiring and installation.

[0011] Preferably, the second battery compartment is disposed close to the end of the first battery compartment, and the second battery compartment is opposite to the uphill and / or downhill ramps of the parking platform.

[0012] In this design, the structure is positioned so that the second battery compartment is located away from the uphill and downhill ramps of the parking platform, reducing the interference of electric non-motorized vehicle battery swapping on the parking platform and simultaneously improving the safety of both non-motorized vehicle and motorized vehicle battery swapping.

[0013] Preferably, the opening of the second battery compartment is oriented parallel to or perpendicular to the driving direction of the parking platform and opposite to it.

[0014] In this design, the second battery pack is positioned relatively far from the parking platform, which reduces interference with the parking platform caused by battery swapping personnel or equipment, thus improving the safety of the battery swapping operation.

[0015] Preferably, the second battery compartment includes a second battery rack with a plurality of second compartments arranged in a matrix, each of the second compartments having an independently opening and closing door at its battery access port.

[0016] In this design, the second battery packs are distributed in multiple second compartments, facilitating targeted retrieval by personnel. Furthermore, if one second battery pack is damaged, it is unlikely to affect the second battery packs in other second compartments, thus providing a safe environment for the storage of each second battery.

[0017] Preferably, the bottom of the second battery compartment is provided with a walking mechanism to move the second battery compartment away from the first battery compartment.

[0018] In this design, the structure uses a walking mechanism to move the second battery compartment, facilitating its transportation and eliminating the need for hoisting operations. Furthermore, the second battery compartment is flexible and can be moved around to adjust its position as needed, making it easy to inspect and maintain.

[0019] Preferably, the second battery compartment is provided with an openable and closable access door on its rear side facing the first battery compartment, and the access door covers multiple second compartments when closed.

[0020] In this design, the maintenance door can cover multiple compartments, effectively sealing off the second battery compartment and making it an independent, enclosed compartment, facilitating flexible configuration of the second battery compartment. Furthermore, the maintenance door is located on the back of the second battery compartment and between the first and second compartments, preventing personnel swapping batteries for non-motorized vehicles from accidentally opening the maintenance door during the swapping operation, thus enhancing safety.

[0021] Preferably, the inner wall of the inspection door facing the second battery rack is provided with a plurality of electrical connection modules, and the plurality of electrical connection modules are respectively provided in correspondence with the plurality of second compartments to make electrical connections with the corresponding second battery packs.

[0022] In this design, the maintenance door covers multiple compartments when closed, while the second battery pack can be charged through the electrical connection module on the maintenance door. Furthermore, opening the maintenance door exposes multiple electrical connection modules, facilitating their maintenance. The structure is simple.

[0023] Preferably, the multiple second compartments of the second battery compartment have a preset tilt angle, and a stop mechanism is provided at the end of each second compartment near the electrical connection module. After the maintenance door is opened, the stop mechanism is closed to allow the second battery pack in the corresponding second compartment to quickly detach.

[0024] In this design, the tilt angle of the second compartment facilitates the loading and unloading of the second battery pack by the battery swapping personnel. The stop mechanism limits the movement of the second battery pack to prevent it from colliding with the maintenance door when it is placed in the second compartment, and also prevents the battery pack from falling off directly when the maintenance door is opened.

[0025] Preferably, the multi-functional battery swapping station further includes a bidirectional charging device connected to the incoming power supply. The first battery pack and the second battery pack are respectively connected to the bidirectional charging device through corresponding electrical connection modules, so that the first battery pack discharges to the second battery pack.

[0026] Alternatively, the second battery pack discharges to the first battery pack; or the first battery pack and / or the second battery pack supplies power to the grid.

[0027] In this scheme, the structure is designed such that when the second battery pack has insufficient power and the power grid is under high load, or according to actual economic needs, the first battery pack can charge the second battery pack by controlling the bidirectional charging device, thereby meeting the battery swapping needs of electric non-motorized vehicles. Similarly, when the first battery pack has insufficient power, the second battery pack can supply power to the first battery pack to meet the battery swapping needs of electric motorized vehicles. In addition, the first and second battery packs can serve as energy storage devices. When the power grid is under low load, the first and second battery packs can be charged by the power grid, thereby storing energy in the first and second battery packs. When the power grid is under high load, the first and second battery packs can supply power to the power grid, thereby alleviating the power supply pressure on the power grid.

[0028] This invention also discloses a battery swapping method for a multi-functional battery swapping station, applied to the aforementioned multi-functional battery swapping station, comprising the following steps:

[0029] In response to the second battery swapping request, the second battery swapping request is for swapping the battery of an electric non-motorized vehicle;

[0030] Acquire the second compartment containing a fully charged second battery pack;

[0031] Control the opening of the door to the second compartment;

[0032] The compartment door is closed after the second battery pack is removed from the second compartment.

[0033] In this solution, upon receiving a battery swapping request from an electric non-motorized vehicle, the system automatically acquires the second compartment of a fully charged second battery pack and controls the compartment door to open, thereby enabling battery swapping of the electric non-motorized vehicle and improving battery swapping efficiency.

[0034] Preferably, before the step of obtaining the second compartment containing the fully charged second battery pack, the method further includes:

[0035] Obtain the second compartment on the second battery rack that is in an idle state, and control the opening of the compartment door;

[0036] After the second battery pack is placed in the second compartment, the compartment door is closed.

[0037] In this solution, instead of first removing the fully charged second battery pack, the depleted second battery pack from the electric non-motorized vehicle is first removed and placed in the second compartment, and then the fully charged second battery pack is removed for battery swapping. The steps are simple and reasonable, avoiding the intermediate storage of the second battery pack and improving battery swapping efficiency.

[0038] Preferably, before the step of obtaining the second compartment in an idle state on the second battery rack, the method further includes:

[0039] Obtain the battery pack model number for electric non-motorized vehicles;

[0040] Obtain a second compartment that is of the same model as the battery pack and is currently idle.

[0041] This solution enables battery swapping for various models of electric non-motorized vehicles, while avoiding the mixing of different models of second battery packs, thus ensuring accurate battery swapping.

[0042] Preferably, before the step of responding to the second battery swapping request, the method further includes:

[0043] Get battery swap request;

[0044] The battery swapping request is determined to be either a first battery swapping request or a second battery swapping request, wherein the first battery swapping request is for swapping the battery of an electric motor vehicle.

[0045] In this solution, the battery swapping station determines whether to swap batteries for electric motor vehicles or electric non-motorized vehicles based on different battery swapping requests. This avoids accidental battery swapping of motor vehicles and non-motorized vehicles, ensuring the safety and efficiency of battery swapping. The entire battery swapping station uses a single battery swapping control system, saving costs.

[0046] The positive and progressive effects of this invention are as follows: by integrating the second battery compartment for swapping batteries for electric non-motorized vehicles with the first battery compartment, it is possible to swap batteries for electric non-motorized vehicles while simultaneously swapping batteries for electric motorized vehicles; the second battery compartment and the first battery compartment share the same auxiliary equipment of the same battery swapping station, saving the construction cost and floor space required for swapping batteries for non-motorized vehicles.

[0071] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0072] Example

[0073] like Figures 1-7As shown, this embodiment provides a multi-functional battery swapping station 100 for swapping batteries of electric motor vehicles. The battery swapping station 100 includes a parking platform 10 for parking electric motor vehicles for battery swapping, a first battery compartment 20 disposed on at least one side of the parking platform 10, and a battery swapping device 30 for removing or installing batteries in electric motor vehicles. The first battery compartment 20 stores a first battery pack for swapping batteries in electric motor vehicles. The multi-functional battery swapping station 100 also includes a second battery compartment 40 electrically connected to the first battery compartment 20, which stores a second battery pack for swapping batteries in electric non-motorized vehicles.

[0074] In this embodiment, the multi-functional battery swapping station 100 integrates the second battery compartment 40 for swapping batteries for electric non-motorized vehicles with the first battery compartment 20, enabling battery swapping for electric motorized vehicles as well as electric non-motorized vehicles. The second battery compartment 40 and the first battery compartment 20 share the same auxiliary equipment of the battery swapping station 100, saving the construction cost and floor space for non-motorized vehicle battery swapping.

[0075] In addition, such as Figure 1 As shown, there are four second battery compartments 40. The actual number of second battery compartments 40 can be set according to specific battery swapping needs, as long as it does not affect the structure and operation of other facilities within the battery swapping station 100. For example, as... Figure 3 As shown in Figure 4, if a monitoring room is set up on one side of the first battery compartment 20 on one side of the battery swapping station 100, then the second battery compartment 40 will not be set up in that area.

[0076] like Figures 3-4c As shown, the first battery compartment 20 is located on either side of the parking platform 10 along the direction of travel A of the electric motorized vehicle. The first battery compartment 20 includes a first battery rack 201 with multiple first compartments 202 arranged vertically. The second battery compartment 40 is located close to the first battery rack 201 and within the coverage area of ​​the first battery compartment 20. By placing the second battery compartment 40 close to the first battery rack 201, the first battery rack 201 can provide some support for the second battery compartment 40, and the structure is more compact. At the same time, placing the second battery compartment 40 in the area opposite to the first battery compartment 20 makes reasonable use of the original space occupied by the battery swapping station 100, making the overall structural layout of the battery swapping station 100 reasonable and aesthetically pleasing. Of course, in other alternative embodiments, the second battery compartment 40 can also be relatively far away from the first battery compartment 20, that is, the second battery compartment 40 is not located within the coverage area of ​​the first battery compartment 20.

[0077] In another embodiment, the first battery compartment 20 is recessed to form a receiving area for storing the second battery compartment 40. A through hole for passing electrical connection lines is provided on any side wall of the receiving area. The second battery compartment 40 is located within the planar area of ​​the first battery compartment 20, making the structure of the second battery compartment 40 and the first battery compartment 20 more compact and aesthetically pleasing. By placing the through hole for the electrical connection lines on the side wall of the receiving area, the distance of the electrical connection lines is shortened, reducing installation difficulty. In other alternative embodiments, the first battery compartment 20 may not have an inwardly recessed receiving area, and the second battery compartment 40 may be positioned close to the side of the first battery compartment 20.

[0078] like Figure 3 As shown, the second battery compartment 40 is disposed close to the end 203 of the first battery compartment 20, and the second battery compartment 40 is opposite to the uphill and / or downhill ramps of the parking platform 10. This arrangement keeps the second battery compartment 40 away from the uphill and downhill ramps of the parking platform 10, reducing interference with the parking platform 10 during battery swapping of electric non-motorized vehicles and improving the safety of battery swapping. Of course, in other alternative embodiments, the second battery compartment 40 may not be disposed at the end 203 of the first battery compartment 20; that is, the second battery compartment 40 may be disposed between the two ends 203 of the first battery compartment 20.

[0079] like Figure 3 and Figure 5 As shown, the orientation of the access port of the second battery compartment 40 is either parallel to or perpendicular to and opposite to the driving direction of the parking platform 10. The access position of the second battery pack is relatively far from the parking platform 10, reducing interference to the parking platform 10 by the battery swapping personnel or the battery swapping equipment 30 when swapping batteries for non-motorized vehicles, thus improving operational safety. Of course, in other alternative embodiments, the orientation of the access port of the second battery compartment 40 can also be perpendicular to and opposite to the driving direction of the parking platform 10.

[0080] like Figure 5 As shown, the second battery compartment 40 includes a second battery rack 401 with multiple second compartments 402 arranged in a matrix. Each second compartment 402 has an independently opening and closing door at its battery access port. The second battery packs are distributed in the multiple second compartments 402 for easy access. Moreover, if one second battery pack is damaged, it is unlikely to affect the other second battery packs, thus improving the safety of second battery storage.

[0081] like Figure 5 and Figure 6As shown, the bottom of the second battery compartment 40 is equipped with a traveling mechanism 403 to move the second battery compartment 40 away from the first battery compartment 20. The traveling mechanism 403 facilitates the transportation of the second battery compartment 40, eliminating the need for hoisting operations. Furthermore, the second battery compartment 40 is flexible, allowing for easy adjustment of its position as needed, and also facilitating inspection and maintenance. Of course, in other alternative embodiments, the second battery compartment 40 may not have the traveling mechanism 403.

[0082] like Figure 6 As shown, the second battery compartment 40, facing the first battery compartment 20, has an openable and closable inspection door 404 on its rear side. When closed, the inspection door 404 covers multiple second compartments 402. The inspection door 404 covers multiple compartments, effectively sealing the second battery compartment 40, making it an independent, enclosed compartment, facilitating flexible placement of the second battery compartment 40. Furthermore, the inspection door 404, located on the rear of the second battery compartment 40 and between the first and second compartments 202, prevents accidental opening by battery swapping personnel, enhancing safety. Of course, in other alternative embodiments, the inspection door 404 can also be located on the side of the second battery compartment 40.

[0083] Specifically, in this embodiment, the inner wall of the inspection door 404 facing the second battery rack 401 is provided with multiple electrical connection modules (not shown in the figure). Each of the multiple electrical connection modules is respectively configured to correspond one-to-one with a multiple second compartment 402 to electrically connect with the corresponding placed second battery pack. When the inspection door 404 is closed, it covers multiple compartments to achieve sealing, while the second battery pack can be charged through the electrical connection modules on the inspection door 404. Furthermore, opening the inspection door 404 exposes the multiple electrical connection modules, facilitating their maintenance.

[0084] like Figure 7 As shown, the second battery compartment 40 has multiple second compartments 402 with preset tilt angles. A stop mechanism 405 is provided at the end 203 near the electrical connection module of each second compartment 402. After the maintenance door 404 is opened, the stop mechanism 405 closes to allow the second battery pack in the corresponding second compartment 402 to quickly detach. The tilt angle of the second compartment 402 facilitates the loading and unloading of the second battery pack by battery swapping personnel. The stop mechanism 405 limits the movement of the second battery pack, preventing it from colliding with the maintenance door 404 when placed in the second compartment 402, and also preventing the battery pack from falling directly when the maintenance door 404 is opened.

[0085] Specifically, in this embodiment, the multi-functional battery swapping station 100 also includes a bidirectional charging device, which is connected to the incoming power supply. The first battery pack and the second battery pack are respectively connected to the bidirectional charging device through corresponding electrical connection modules, so that the first battery pack discharges to the second battery pack.

[0086] Alternatively, the second battery pack can discharge to the first battery pack; or the first and / or second battery packs can supply power to the grid. When the second battery pack has insufficient power and the grid is under high load, or according to actual economic needs, the first battery pack can be charged to the second battery pack by controlling the bidirectional charging device, thereby meeting the battery swapping needs of electric non-motorized vehicles. Similarly, when the first battery pack has insufficient power, the second battery pack can supply power to the first battery pack to meet the battery swapping needs of electric motorized vehicles. In addition, the first and second battery packs can serve as energy storage devices. When the grid is under low load, the first and second battery packs can be charged by the grid, thereby storing energy in the first and second battery packs. When the grid is under high load, the first and second battery packs can supply power to the grid, thereby alleviating the power supply pressure on the grid.

[0087] Specifically, the bidirectional charging device has a rectification state and an inverter state. When the bidirectional charging device is in the rectification state, the first battery pack or the second battery pack is charged; when the bidirectional charging device is in the inverter state, the first battery pack or the second battery pack is discharged. A controller is connected to the bidirectional charging device and is used to control the switching between the rectification state and the inverter state so that the first battery pack and the second battery pack are charged or discharged respectively. The charging principle of the bidirectional charging device is prior art, and can be found in Chinese invention patent (patent application number: 2021234490606), which will not be elaborated here.

[0088] like Figure 2 As shown, this embodiment also provides a battery swapping method for a multi-functional battery swapping station 100, applicable to any of the above-described multi-functional battery swapping stations 100, including the following steps:

[0089] Step S101: Respond to the second battery swapping request, the second battery swapping request being to swap the battery of the electric non-motorized vehicle;

[0090] Step S102: Obtain the second compartment 402 containing a fully charged second battery pack;

[0091] Step S103: Control the opening of the door of the second compartment 402;

[0092] Step S104: After the second battery pack in the second compartment 402 is removed, close the compartment door.

[0093] This method, upon receiving a battery swapping request from an electric non-motorized vehicle, automatically acquires the second compartment 402 of a fully charged second battery pack and controls the compartment door to open, thereby enabling battery swapping of the electric non-motorized vehicle and improving battery swapping efficiency.

[0094] Specifically, in this embodiment, more preferably, before performing step S102, the following steps are also included: obtaining the second compartment 402 that is in an idle state on the second battery rack 401, and controlling the opening of the compartment door of the second compartment 402;

[0095] After the second battery pack is placed in the second compartment 402, the compartment door is closed.

[0096] This preferred method, compared to first removing the fully charged second battery pack from the electric non-motorized vehicle and placing it in the second compartment 402, and then removing the fully charged second battery pack for battery swapping, has a simpler overall process and avoids problems such as having nowhere to store or placing the second battery pack randomly during the transfer process, thus improving battery swapping efficiency.

[0097] Specifically, in this embodiment, more preferably, before the step of obtaining the second compartment 402 that is in an idle state on the second battery rack 401, the method further includes:

[0098] Obtain the battery pack model number for electric non-motorized vehicles;

[0099] Obtain the second compartment 402, which is of the same model as the battery pack and is currently idle.

[0100] It can swap batteries for various models of electric non-motorized vehicles and avoid mixing different models of second battery packs, ensuring accurate battery swapping.

[0101] Specifically, in this embodiment, more preferably, before responding to the second battery swapping request, the method further includes: obtaining a battery swapping request; determining whether the battery swapping request is a first battery swapping request or a second battery swapping request, wherein the first battery swapping request is for swapping the battery of an electric motor vehicle.

[0102] The battery swapping station 100 judges different battery swapping requests to perform battery swapping for electric motor vehicles and electric non-motorized vehicles, avoiding accidental battery swapping of motor vehicles and non-motorized vehicles, ensuring the safety and efficiency of battery swapping, and realizing the sharing of a single battery swapping control system for the entire battery swapping station, thus saving costs.

[0103] The multi-functional battery swapping station 100 in this embodiment can swap batteries for electric motor vehicles and electric non-motorized vehicles at the same time, saving on the construction cost and land area for battery swapping of non-motorized vehicles.
