Description

Technical Field

[0001] The present invention relates to the technical field of vehicle battery replacement, and in particular to a battery replacement system and a battery replacement method. Background Art

[0002] With the development and progress of battery technology, researchers have developed new cars based on electric energy. In the field of new energy vehicles, the battery box is an energy storage device designed specifically for new energy vehicles. It can store a large amount of electric energy, provide continuous power support for the vehicle, and reduce energy consumption and pollution emissions. The battery box reduces energy consumption and pollution emissions and improves driving convenience. Battery swapping technology refers to the technology of removing the battery box of a new energy vehicle that has been attenuated or exhausted from the body and replacing it with a fully charged battery box. It can improve the cycle life and utilization rate of the battery box, which is beneficial to environmental protection and sustainable development.

[0003] Usually, due to the high energy consumption or long driving range requirements of vehicles, multiple battery boxes need to be carried for driving. Since there are multiple rows of charging seats in the battery swap station, the minimum spacing between the charged battery boxes on two adjacent rows of charging seats is usually small in order to improve space utilization. In addition, since the vehicle is close to the battery swap station, the low-power battery boxes removed from the vehicle are prone to collide with the battery swap station and the charged battery boxes in the battery swap station during movement. Each battery box needs to be aligned once, and the vehicle needs to be moved and positioned multiple times when swapping multiple battery boxes, which makes the battery swap efficiency low.

The grabbing unit can grab a low-power battery box with the bottom end lower than or flush with the top end of the battery box after charging. In this way, the height of the first cabin can be lowered and the battery swap can still be carried out normally without collision, thereby improving the battery swap efficiency, effectively improving the space utilization rate and saving construction costs.

[0034] The battery box is an energy storage device specially designed for new energy vehicles 02. It can store a large amount of electrical energy, provide continuous power support for the vehicle 02, and reduce energy consumption and pollution emissions. Due to the high energy consumption of the vehicle 02, multiple battery boxes need to be set up for driving. There are multiple rows of charging seats in the battery swap station 01. In order to achieve high space utilization, the minimum spacing between the charged battery boxes 114 on two adjacent rows of charging seats is usually small, which causes multiple low-power battery boxes 22 to easily collide during battery swapping. Each low-power battery box 22 needs to be aligned once. In order to align each low-power battery box 22 once, the vehicle 02 needs to be moved and positioned multiple times, resulting in low battery swap efficiency. In order to solve the problem of how to improve the efficiency of battery swapping, this embodiment provides a battery swapping system. Figure 1As shown, the battery exchange system may include: a battery exchange station 01 and a vehicle 02. The battery exchange station 01 may include a first cabin unit 11, a second cabin unit 12, and a grabbing unit 14. The first cabin unit 11 may include a first cabin 111, a plurality of first charging seats 112, a plurality of second charging seats 113, and a plurality of charged battery boxes 114. The vehicle 02 may include a vehicle portion 21 and a plurality of low-power battery boxes 22. The low-power battery box 22 may be detachably and electrically connected to the vehicle portion 21, so as to facilitate the removal of the low-power battery box 22 when replacing the battery. The first charging seat 112 and the second charging seat 113 are used to charge the low-power battery box 22. The first charging seat 112 and the second charging seat 113 may be respectively arranged in the space surrounded by the first cabin 111 to protect the first charging seat 112 and the second charging seat 113. The first charging seat 112 and the second charging seat 113 can be arranged at intervals along the width direction of the first cabin 111, so that a battery replacement channel is formed between the first charging seat 112 and the second charging seat 113, which is used to provide space for the movement of the low-power battery box 22 and the battery box 114 after charging, so as to avoid collision between the low-power battery box 22 or the battery box 114 after charging during battery replacement. Multiple first charging seats 112 can be arranged at intervals along the length direction of the first cabin 111, and multiple second charging seats 113 can be arranged at intervals along the length direction of the first cabin 111, so as to provide space for the low-power battery box 22 or the battery box 114 after charging to dissipate heat. The first cabin 111 and the second cabin unit 12 can be detachably connected along the length direction of the first cabin 111, so as to facilitate the installation and disassembly of the first cabin 111 and the second cabin unit 12. The battery box 114 after charging can be detachably connected and electrically connected to the first charging seat 112, and the battery box 114 after charging can be detachably connected and electrically connected to the second charging seat 113, so that the battery box 114 after charging can be removed or installed from the first charging seat 112 and the second charging seat 113. The low-power battery box 22 can be detachably connected and electrically connected to the first charging seat 112, and the low-power battery box 22 can also be detachably connected and electrically connected to the second charging seat 113, and can be used to charge the low-power battery box 22. The number A of the battery boxes 114 after charging can be equal to the number B of the first charging seat 112 plus the number C of the second charging seat 113 minus one, so as to ensure that there is an idle first charging seat 112 or an idle second charging seat 113, so that when the vehicle 02 is replaced, the low-power battery box 22 on the vehicle part 21 can be placed on the idle first charging seat 112 or the idle second charging seat 113, so that there is a position on the vehicle part 21 where the battery box 114 after charging can be installed. The first cabin 111 and the second cabin unit 12 can be detachably connected to the grabbing unit 14 , respectively, to facilitate the disassembly and installation of the grabbing unit 14 .The minimum distance E between the first charging seat 112 and the second charging seat 113 may be greater than 1.2 times the dimension D of the battery box 114 along the width direction of the first compartment 111 after charging and less than 1.5 times the dimension D of the battery box 114 along the width direction of the first compartment 111 after charging. The dimension of the first charging seat 112 along the width direction of the first compartment 111 may be equal to the dimension of the battery box 114 along the width direction of the first compartment 111 after charging, and the dimension of the second charging seat 113 along the width direction of the first compartment 111 may be equal to the dimension of the battery box 114 along the width direction of the first compartment 111 after charging. In this way, ensuring that the minimum distance between the first charging seat 112 and the second charging seat 113 is small facilitates improving the space utilization rate of the first compartment 111 and reducing the construction cost, while making the minimum distance between the first charging seat 112 and the second charging seat 113 sufficient for the movement of the low-power battery box 22 on the grabbing unit 14. The dimension F of the charged battery box 114 along the length direction of the first compartment 111 can be less than or equal to the dimension G of the second compartment unit 12 along the length direction of the first compartment 111, so that the second compartment unit 12 can accommodate the low-power battery box 22 or the charged battery box 114.

[0035] The length, width and height of the low-power battery box 22 can be equal to the length, width and height of the battery box 114 after charging, ensuring that the low-power battery box 22 and the battery box 114 after charging are of the same model and can be exchanged. The vehicle 02 can be parked on the side of the second cabin unit 12 away from the first cabin unit 11. In this way, the grabbing unit 14 can grab the low-power battery box 22 on the vehicle 02 and put it into the second cabin unit 12 during the battery exchange process. The grabbing unit 14 can drive the low-power battery box 22 to move a set distance toward the symmetric plane of the first charging seat 112 and the second charging seat 113 along the width direction of the first cabin 111 in the second cabin unit 12. After moving the set distance, the minimum spacing between the symmetric plane of the low-power battery box 22 along the width direction of the first cabin 111 and the symmetric plane of the first charging seat 112 and the second charging seat 113 along the width direction of the first cabin 111 is less than the first set range (for example, the first set range can be 1 / 10 of the size of the low-power battery box 22 along the width direction of the first cabin 111), which can avoid collision during the battery exchange process. After the movement, the grabbing unit 14 can drive the low-power battery box 22 to move to the idle first charging seat 112 or the idle second charging seat 113, and then the grabbing unit 14 will move the charged battery box 114 with the highest power to the vehicle part 21, thereby completing the battery replacement. In this way, when the minimum distance between the first charging seat 112 and the second charging seat 113 is small, it is possible to avoid collisions between the low-power battery box 22 during the battery replacement process, reduce the number of times the vehicle 02 is moved, and smoothly replace power for multiple low-power battery boxes 22, thereby improving the battery replacement efficiency. The minimum distances between the first charging seat 112 and the second charging seat 113 and the first compartment 111 are not enough to accommodate the low-power battery box 22 to pass through, which can reduce the width dimension of the first compartment 111, making the first compartment 111 more compact and cost-saving.

[0036] The battery swap system may include a battery swap state. The battery swap state may include the vehicle 21 stopping in the battery swap area of ​​the battery swap station 01 and the minimum spacing H between the second cabin unit 12 and the low-power battery box 22 on the vehicle 21 is greater than 0 and less than 0.33 times the dimension F of the battery box 114 after charging along the length direction of the first cabin 111. In this way, the spacing between the second cabin unit 12 and the low-power battery box 22 on the vehicle 21 during battery swap can be small, the moving distance of the grabbing unit 14 can be reduced to improve the battery swap efficiency, and the arrangement of the track path for the grabbing unit 14 to move can reduce costs. The bottom end of the grabbing unit 14 grabbing a low-power battery box 22 can be lower than or flush with the top of the battery box 114 after charging (the battery box 114 after charging can be located at the first charging seat 112 or the second charging seat 113 is not grabbed at this time). In this way, the height of the first cabin 111 can be reduced, effectively improving space utilization and saving construction costs.

[0037] In some embodiments, the second cabin unit 12 may include a second cabin 121 and a first door 125. The first cabin 111, the first door 125, and the second cabin 121 may be detachably connected in sequence along the length direction of the first cabin 111, so as to facilitate the disassembly and installation of the first cabin 111, the first door 125, and the second cabin 121. The power exchange system may also include a first state and a second state. The first state may include the first cabin 111 and the first door 125 enclosing a sealed space, and the second state may include the first cabin 111, the second cabin 121, and the external space being interconnected. When the battery swap station 01 is in a high-cold, high-temperature, and high-dust environment, the first door 125 can be used to isolate the sealed space formed by the first cabin 111 and the first door 125 from the harsh external environment. The sealed space formed by the first cabin 111 and the first door 125 can protect the charged battery box 114, the first charging seat 112, and the second charging seat 113 from damage, and can extend the service life of the charged battery box 114, the first charging seat 112, and the second charging seat 113.

[0038] In some embodiments, the second cabin unit 12 may further include a second door 126. The first door 125, the second cabin 121, and the second door 126 may be detachably connected in sequence along the length direction of the first cabin 111, so as to facilitate the disassembly and installation of the first door 125, the second cabin 121, and the second door 126. The first state may further include that the first door 125 and the first cabin 111 surround a sealed space and the first door 125, the second cabin 121, and the second door 126 surround another sealed space. The second state may further include that the first cabin 111, the second cabin 121, and the external space are interconnected. The low-power battery box 22 entering the second compartment 121 can be protected from the harsh external environment. In this way, after the low-power battery box 22 enters the second compartment 121 from the second door 126, the second door 126 can be closed and then the first door 125 can be opened to prevent external dust from entering the first compartment 111. The battery box 114, the first charging seat 112, and the second charging seat 113 after charging can be protected from dust pollution, reducing the impact of dust on the performance of the first charging seat 112 and the second charging seat 113, reducing the harm of combustible dust and conductive dust to the first charging seat 112 and the second charging seat 113, preventing the first charging seat 112 and the second charging seat 113 from overheating, and avoiding safety accidents such as short circuits and fires. It can prevent dust from affecting the heat dissipation of the battery box 114 after charging, and can also slow down the temperature change rate in the first compartment 111 during battery replacement to avoid affecting the charging efficiency of the battery box 114 after charging.

[0039] In some embodiments, the first cabin unit 11 may further include a thermostatic module 115, which may be detachably connected to the first cabin 111, facilitating installation of the thermostatic module 115, and allowing for separate repairs when the thermostatic module 115 fails, thereby saving costs. The thermostatic module 115 may control the temperature of the first cabin 111, ensuring that the battery box 114 is charged at a suitable temperature after charging, thereby improving charging efficiency, extending the service life of the battery box 114 after charging, and reducing the risk of safety accidents caused by overheating.

[0040] In some embodiments, the second cabin unit 12 may further include a cleaning module 123, which may be detachably connected to the second cabin 121, so as to facilitate the installation of the cleaning module 123. When the cleaning module 123 fails, it may be repaired separately to save costs. After the grabbing unit 14 brings the low-power battery box 22 into the second cabin unit 12, when the first door 125 and the second door 126 are both closed, the cleaning module 123 may clean the low-power battery box 22, clean the mud and snow that may exist on the low-power battery box 22, and prevent the dirt attached to the low-power battery box 22 from entering the first cabin 111 with the low-power battery box 22, so as to prevent the dirt from damaging the first charging seat 112 and the second charging seat 113.

[0041] In some embodiments, the second compartment unit 12 may further include a detection module 122, which may be detachably connected to the second compartment 121, so as to facilitate the installation of the detection module 122, and to save costs by performing separate repairs when a fault occurs in the detection module 122. When both the first door 125 and the second door 126 are closed, the detection module 122 may detect various parameters (such as appearance and temperature) to ensure the safety and performance of the low-power battery box 22, and to facilitate taking maintenance measures based on the detection data of the low-power battery box 22, thereby increasing the service life of the low-power battery box 22.

[0042] In other embodiments, after the cleaning module 123 cleans the low-battery box 22, the detection module 122 can detect various parameters (such as appearance, temperature), and the cleaning can eliminate possible dirt on the low-battery box 22, thereby ensuring the accuracy of the detection result. The surface of the low-battery box 22 after cleaning is clean, which is conducive to better contact and perception of the low-battery box 22 by the detection module 122, thereby improving the sensitivity of the detection module 122.

[0043] In some embodiments, the second cabin unit 12 may further include a temperature control module 124, which may be detachably connected to the second cabin 121, so as to facilitate the installation of the temperature control module 124. When the temperature control module 124 fails, it may be repaired separately to save costs. When the low-power battery box 22 enters the second cabin 121, when the first door 125 and the second door 126 are both closed, the temperature control module 124 may control the temperature of the second cabin 121 to adjust the temperature of the low-power battery box 22, reduce the temperature difference after the low-power battery box 22 enters the first cabin 111, and prevent the condensed water generated by the sudden change in temperature of the low-power battery box 22 from damaging the first charging seat 112 and the second charging seat 113 in the first cabin 111, and also prevent the temperature of the low-power battery box 22 in the external high-temperature environment from affecting the charging efficiency of the first charging seat 112 and the second charging seat 113.

[0044] In some embodiments, the battery replacement state may also include at least two adjacent low-battery boxes 22 on the vehicle part 21 being within the range of the projection of the second cabin unit 12 toward the direction close to the vehicle 02, and the range of the grabbing unit 14 grabbing the low-battery box 22 and the charged battery box 114 covers at least two adjacent low-battery boxes 22 on the vehicle part 21. In this way, when the grabbing area of ​​the grabbing unit 14 is compactly arranged, the grabbing unit 14 can grab a low-battery box 22 when the vehicle 02 stops for a single battery replacement. After the battery replacement is completed, the grabbing unit 14 can continue to grab another adjacent low-battery box 22 without the vehicle 02 moving again. This can reduce the layout area of ​​the moving track path of the grabbing unit 14, save costs, and improve the battery replacement efficiency.

[0045] In some embodiments, Figure 2As shown, the grabbing unit 14 may include a trolley track 141, a trolley body 142, a trolley track 143, a trolley body 144, and a grabbing portion 145. The trolley track 141 may be detachably connected to the first cabin 111 and the second cabin unit 12, respectively, to facilitate the removal and installation of the trolley track 141. The trolley body 142 may be slidably connected to the trolley track 141, and the trolley body 142 may move along the length direction of the first cabin 111 on the trolley track 141, so that when the trolley body 142 moves, it can drive the low-power battery box 22 or the charged battery box 114 to move along the length direction of the first cabin 111 on the trolley track 141. The trolley track 143 may be detachably connected to the trolley body 142, to facilitate the removal and installation of the trolley track 143. The trolley body 144 may be slidably connected to the trolley track 143, to facilitate the trolley body 144 to slide freely on the trolley track 143. The trolley body 144 can move along the width direction of the first compartment 111 on the trolley track 143, so that when the trolley body 144 moves, it can drive the low-power battery box 22 or the charged battery box 114 to move along the width direction of the first compartment 111 on the trolley track 143. The trolley body 144 can be connected to the gripping part 145, and the gripping part 145 can be raised and lowered under the drive of the trolley body 144, and the gripping part 145 can be driven to grab the low-power battery box 22 or the charged battery box 114. In this way, the lifting and lowering of the gripping part 145 can be controlled, so that the gripping part 145 drives the low-power battery box 22 or the charged battery box 114 to achieve lifting and lowering.

[0046] The battery replacement state may also include that when the cart body 144 moves a low-power battery box 22 through the grabbing portion 145, the bottom end of the low-power battery box 22 may be lower than or flush with the top end of the charged battery box 114 (the charged battery box 114 may be located at the first charging seat 112 or the second charging seat 113 is not grabbed at this time). In this way, the height of the first cabin 111 can be lowered, effectively improving space utilization and saving construction costs.

[0047] In other embodiments, the battery swap station 01 may further include a third cabin unit 13, which may protect the vehicle 02 from damage to the low-power battery box 22 by the harsh external environment. The first cabin unit 11, the second cabin unit 12, and the third cabin unit 13 may be detachably connected in sequence along the length direction of the third cabin unit 13, so as to facilitate the installation and removal of the third cabin unit 13 and the second cabin unit 12. The trolley track 141 may be detachably connected to the third cabin unit 13, so that the trolley body 142 may drive the low-power battery box 22 or the charged battery box 114 to move along the length direction of the third cabin unit 13 on the trolley track 141 when the trolley track 141 moves.

[0048] In some embodiments, Figure 3As shown, the battery replacement method may include steps S11 to S17, and each step will be described in detail below.

[0049] Step S11, based on the vehicle 02 arriving at the battery replacement area, the capture unit 14 obtains the position of the low-power battery box 22 on the vehicle 21, the idle first charging seat 112 or the idle second charging seat 113;

[0050] Step S12, based on the position of the low-power battery box 22 on the vehicle 21 acquired by the grabbing unit 14, the grabbing unit 14 grabs the low-power battery box 22;

[0051] Step S13, based on the grabbing unit 14 grabbing the low-power battery box 22, the grabbing unit 14 drives the low-power battery box 22 to move into the second cabin unit 12;

[0052] Step S14, based on the low-power battery box 22 moving into the second compartment unit 12, the gripping unit 14 drives the low-power battery box 22 to move a set distance toward a set plane; wherein the set plane includes a symmetric plane of the first charging seat 112 and the second charging seat 113 along the width direction of the first compartment 111;

[0053] Step S15, based on the low-power battery box 22 moving a set distance toward the set plane, the grabbing unit 14 drives the low-power battery box 22 to move to the idle first charging seat 112 or the idle second charging seat 113;

[0054] Step S16, based on the low-power battery box 22 being located in the idle first charging seat 112 or the idle second charging seat 113, obtaining the position of the charged battery box 114 with the highest power;

[0055] In step S17 , based on the position of the charged battery box 114 with the highest power, the grabbing unit 14 moves the charged battery box 114 with the highest power to the vehicle portion 21 .

[0056] In some embodiments, step S11, when the vehicle 02 arrives at the battery replacement area, the minimum spacing between the symmetric plane of the multiple low-power battery boxes 22 on the vehicle 21 along the width direction of the first compartment 111 and the set plane (the set plane can be the symmetric plane of the first charging seat 112 and the second charging seat 113 along the width direction of the first compartment 111) can be less than the second set range (for example, the second set range can be 1 / 10 of the size of the low-power battery box 22 along the width direction of the first compartment 111), thereby reducing the layout area of ​​the track path of the movement of the grab unit 14 and saving costs. The grab unit 14 can obtain the position of the low-power battery box 22 on the vehicle 21, the idle first charging seat 112 or the idle second charging seat 113, so as to facilitate the subsequent operation of moving the low-power battery box 22 on the vehicle 21 to the idle first charging seat 112 or the idle second charging seat 113 for charging. It can also reduce the number of times the vehicle 02 moves, smoothly replace the power of multiple low-power battery boxes 22, and thus improve the efficiency of battery replacement.

[0057] In step S12, when the grabbing unit 14 obtains the position of the low-power battery box 22 on the vehicle part 21, the grabbing unit 14 can grab the low-power battery box 22. In this way, the grabbing unit 14 can subsequently move the low-power battery box 22 to the idle first charging seat 112 or the idle second charging seat 113 for charging.

[0058] In step S13 , when the grabbing unit 14 grabs the low-power battery box 22 , the grabbing unit 14 can drive the low-power battery box 22 to move into the second compartment unit 12 , so as to provide displacement space for the low-power battery box 22 .

[0059] In step S14, since the minimum distance between the first charging seat 112 and the second charging seat 113 is small, the grabbing unit 14 moves the low-battery box 22 toward the first compartment 111. The low-battery box 22 may collide with the charged battery box 114 on the first charging seat 112 or the second charging seat 113. When the low-battery box 22 moves into the second compartment unit 12, the grabbing unit 14 can drive the low-battery box 22 to move a set distance toward a set plane. After moving the set distance, the minimum distance between the symmetry plane of the low-battery box 22 along the width direction of the first compartment 111 and the set plane can be less than the first set range (for example, the first set range can be 1 / 10 of the battery size along the width direction of the first compartment 111). The set plane can include the symmetry plane of the first charging seat 112 and the second charging seat 113 along the width direction of the first compartment 111. In this way, collisions can be avoided during battery replacement, and the layout area of ​​the moving track path of the grabbing unit 14 can be reduced, thereby saving costs.

[0060] Step S15, when the low-power battery box 22 moves a set distance toward the set plane, the grabbing unit 14 can drive the low-power battery box 22 to move to the idle first charging seat 112 or the idle second charging seat 113, so as to avoid collision during the battery replacement process.

[0061] Step S16, when the low-power battery box 22 is located in the idle first charging seat 112 or the idle second charging seat 113, the position of the charged battery box 114 with the highest power can be obtained, so that the grabbing unit 14 can move the charged battery box 114 with the highest power to the vehicle part 21 for power supply.

[0062] Step S17, when the position of the charged battery box 114 with the highest power is obtained, the grabbing unit 14 can grab the charged battery box 114 and move it toward the set plane by a set distance. After moving the set distance, the minimum distance between the symmetry plane of the charged battery box 114 along the width direction of the first compartment 111 and the set plane can be less than the first set range (for example, the first set range can be 1 / 10 of the size of the battery along the width direction of the first compartment 111). The grabbing unit 14 can move the charged battery box 114 with the highest power to the vehicle part 21. In this way, collision can be avoided during the battery replacement process.
