Description

Technical Field

[0001] The present invention relates to the field of battery replacement technology, and specifically to a battery replacement station and a battery replacement method. Background Art

[0002] With the development of new energy technology, the number of new energy vehicles on the market is increasing, from small passenger vehicles to large special vehicles, all embarking on the journey of electrification. In order to obtain longer battery life, electric vehicles often use large-capacity batteries. Long battery life is accompanied by longer charging time. It is difficult to meet the huge energy replenishment demand by charging alone, and the charging method has problems such as long charging time and inflexibility. In this context, the battery swap mode came into being and became an important way to shorten the charging time of new energy vehicles.

[0003] For example, the patent with the national authorized patent announcement number CN117104066A discloses a battery swap station and a battery swap method. The battery swap station includes: a battery conveying area, a battery storage area, a battery swap platform and a battery swap channel. The battery swap channel is arranged at the bottom of the battery conveying area, the battery storage area and the battery swap platform; the battery swap channel is provided with a battery conveying line, a cache platform and an unlocking platform. The cache platform is arranged below the battery conveying area for temporarily storing the feeding battery pack; the unlocking platform is arranged below the battery swap platform for installing or unlocking the battery pack on the vehicle; the battery conveying line is arranged above the cache platform and the unlocking platform for transmitting the battery pack. This battery swap station can synchronize the preparation of the fully charged battery pack with the unlocking of the feeding battery pack, which greatly improves the efficiency of battery swapping and enhances the user experience.

[0004] However, the above-mentioned battery swap stations and battery swap methods are unable to charge and detect the power of the replaced batteries to ensure that each replaced battery is fully charged. Instead, the uncharged battery packs need to be sent back to the charging station for charging, which means that these battery packs cannot be put into use immediately while waiting for charging, which increases the turnover time and vacancy status of the battery library and reduces the overall response speed of the battery swap system. Summary of the invention

[0005] The object of the present invention is to provide a battery swap station and a battery swap method to solve the problem in the above-mentioned background technology that the replaced battery cannot be charged and the power level cannot be detected, so as to ensure that each replaced battery is fully charged.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A battery swap station, comprising: a dismantling and swapping platform, a communication port is provided on the upper surface of the dismantling and swapping platform, a reduction motor is fixedly installed at one end of the dismantling and swapping platform, an output shaft of the reduction motor passes through the dismantling and swapping platform and is fixedly connected to a pentagonal turntable, the pentagonal turntable rotates in the dismantling and swapping platform, charging ports are provided on the five sides of the pentagonal turntable, the charging ports are in a stepped connection shape, and the pentagonal turntable can drive the charging port to be flush with the communication port;

[0008] Wherein, mounting grooves are provided on both sides of the charging port, and a suction mechanism is fixedly installed in the mounting groove, and the suction mechanism can suction and fix the removed battery pack in the charging port.

[0009] Preferably, a connecting plate is fixedly installed on one side of the replacement table, the connecting plate is located in the center of the pentagonal turntable, a scissor lift is fixedly installed on the upper surface of the connecting plate, the scissor lift is flush with the charging port, and a battery disassembler is fixedly installed on the upper surface of the scissor lift.

[0010] Preferably, the battery disassembler can be pushed by a scissor lift from the charging port through the connecting port, and the battery disassembler in the connecting port can be lifted up again by the scissor lift to touch the lower end of the vehicle chassis to disassemble the battery pack;

[0011] The disassembled battery pack will fall onto the upper surface of the battery disassembler, so that the scissor lift can descend to allow the battery pack to stay in the charging port for charging.

[0012] Preferably, the charging port can monitor the power level in real time by a battery monitoring chip when charging a battery pack, and each group of the battery monitoring chips can detect the power level of the battery pack in a corresponding group of charging ports.

[0013] Preferably, the signal transmitting end of the battery monitoring chip is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electric control end of the reduction motor.

[0014] Preferably, an active infrared sensor is fixedly installed at one end of each group of charging ports, and each group of active infrared sensors can be driven by a five-cornered turntable to rotate to be flush with a passive infrared sensor, and the passive infrared sensor is fixedly installed on the lower surface of the disassembly and replacement platform;

[0015] Wherein, the signal transmitting ends of the active infrared sensor and the passive infrared sensor are both connected to the signal receiving end of the controller.

[0017] Preferably, the suction mechanism includes a vacuum pump, which is fixedly installed at one end of the pentagonal turntable. The air inlet of the vacuum pump is connected to an air pipe installed therein. The air pipe passes through the pentagonal turntable and the end thereof is connected to a long suction cup installed therein. The long suction cup is fixedly installed in the installation groove.

[0018] Preferably, the long suction cup can be sucked and fixed on both sides of the battery pack in the charging port, so that the battery pack can be limited in the charging port.

[0019] S1. When replacing the battery pack in the car, the car can be driven to the upper surface of the replacement platform so that the battery pack under the car chassis is flush with the connecting port. Then the controller can start the reduction motor to drive the charging port without the battery pack in the pentagonal turntable to be flush with the connecting port. Then the scissor lift can be started to push the battery disassembler on the upper surface through the charging port and into the connecting port. The battery disassembler in the connecting port can be lifted up by the scissor lift for a second time and touch the lower end of the car chassis to disassemble the battery pack. The disassembled battery pack will fall on the upper surface of the battery disassembler, and the scissor lift can be lowered to make the battery pack stay in the charging port for charging.

[0020] S2, and the battery pack placed in the charging port can be fixed on both sides by the long suction cups, and the long suction cups are arranged on both sides of the charging port, so as to limit and fix the battery pack in the charging port;

[0021] S3. The controller can then detect the charging port position where the fully charged battery pack is located through the battery monitoring chip, and simultaneously start the active infrared sensor on the side of the corresponding charging port position, and then start the reduction motor to drive the five-pointed turntable to rotate until the five-pointed turntable drives the active infrared sensor to be flush with the passive infrared sensor, and then send a signal to the controller, and the controller controls the reduction motor to stop working so that the charging port can be accurately flush with the connecting port;

[0022] S4. Then, the scissor lift can be started again and the vacuum pump in the charging port can be stopped to release the long suction cup in the charging port from sucking the battery pack. The lifting of the scissor lift can lift the battery pack out of the charging port through the battery disassembler, so that the battery disassembler can push the battery pack into the battery slot of the car, and at the same time, the battery disassembler can be started to install the battery pack, thus completing the battery pack removal and replacement process.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Through the design of the reduction motor, the pentagonal turntable, the charging port, the scissor lift, the battery disassembler and the suction mechanism, when the battery pack in the car is replaced, the car can be driven to the upper surface of the replacement platform to make the battery pack under the car chassis flush with the connecting port, and then the controller can start the reduction motor to drive the charging port without a battery pack in the pentagonal turntable to be flush with the connecting port, and then the scissor lift can be started to push the battery disassembler on the upper surface from the charging port through the connecting port, and the battery disassembler in the connecting port can be lifted up by the scissor lift for a second time to touch the lower end of the car chassis to disassemble the battery pack, and the disassembled battery pack will fall on the upper surface of the battery disassembler, and the scissor lift can be lowered to make the battery pack stay in the charging port for charging, and the battery pack placed in the charging port can be sucked in the charging port by the suction mechanism, that is, the disassembly operation of the battery pack is completed;

[0025] When the fully charged battery pack is loaded, the reduction motor can be started again to drive the five-angle turntable to rotate. After the fully charged battery pack in the charging port is rotated to be flush with the connecting port, the suction mechanism in the charging port can be stopped to release the limiting force on the battery pack. Then the scissor lift can be started again to drive the battery disassembler to lift the battery pack out of the charging port, so that the battery disassembler can push the battery pack into the battery slot of the car, and the battery disassembler can be started at the same time to install the battery pack, thus completing the removal and replacement process of the battery pack. Through the coordinated work of the reduction motor, the five-angle turntable and the scissor lift, the battery pack can be quickly disassembled and installed, which greatly shortens the battery replacement time and improves the battery replacement efficiency. The replaced battery can be charged by the charging port, so that the battery can be put into use quickly, reducing the idle time of the battery and improving the overall battery turnover efficiency.

[0026] 2. Through the design of battery monitoring chip, active infrared sensor and passive infrared sensor, when the battery is installed in the car, the battery pack in each charging port can be detected by the battery monitoring chip at the charging port position where the fully charged battery pack is located, and the active infrared sensor on the side of the corresponding charging port position is started at the same time. Then the reduction motor can be started to drive the five-pointed turntable to rotate until the five-pointed turntable drives the active infrared sensor to be flush with the passive infrared sensor, then a signal will be sent to the controller. The controller controls the reduction motor to stop working so that the charging port can be accurately flush with the connecting port, so that the replaced battery packs can be fully charged during the replacement process, realizing a fully automatic operation process, reducing manual intervention, and improving the safety and efficiency of operation.

[0027] 3. Through the design of the vacuum pump, air pipe and long suction cup, after the battery pack falls into the charging port, the vacuum pump can be started to fix the long suction cups on both sides of the battery pack through the air pipe, so that the battery pack can be fixed in the charging port, so that the battery pack will not fall out of the charging port during the rotation of the five-pointed turntable, ensuring that the position of the battery pack remains unchanged during the entire battery replacement process, thereby improving the accuracy of the operation.

When replacing a battery pack in a car, the car is driven to the upper surface of the replacement platform (101) so that the battery pack under the car chassis is flush with the connecting port (102). Then, the controller starts the reduction motor (2) to drive the charging port (202) without a battery pack in the pentagonal turntable (201) to be flush with the connecting port (102). Then, the scissor lift (4) is started to push the battery disassembler (401) on the upper surface from the charging port (202) through the connecting port (102). The battery disassembler (401) in the connecting port (102) can be lifted up by the scissor lift (4) for a second time and touches the lower end of the car chassis to disassemble the battery pack. The disassembled battery pack will fall on the upper surface of the battery disassembler (401), and the scissor lift (4) is lowered to make the battery pack stay in the charging port (202) for charging. S2. The battery pack placed in the charging port (202) can be fixed on both sides by the long suction cups (303). The long suction cups (303) are arranged on both sides of the charging port (202), thereby fixing the battery pack in the charging port (202); S3, the controller can then detect the position of the charging port (202) where the fully charged battery pack is located through the battery monitoring chip (205), and simultaneously start the active infrared sensor (204) on the side of the corresponding charging port (202) position, and then start the reduction motor (2) to drive the pentagonal turntable (201) to rotate until the pentagonal turntable (201) drives the active infrared sensor (204) to be flush with the passive infrared sensor (103) and then sends a signal to the controller, and the controller controls the reduction motor (2) to stop working so that the charging port (202) can be accurately flush with the connecting port (102); S4, then the scissor lift (4) is started again and the vacuum pump (301) in the charging port (202) is stopped to release the long suction cup (303) in the charging port (202) from sucking the battery pack. The lifting of the scissor lift (4) can lift the battery pack out of the charging port (202) through the battery disassembler (401), so that the battery disassembler (401) can push the battery pack into the battery slot of the vehicle, and at the same time the battery disassembler (401) is started to install the battery pack, thus completing the process of disassembling and replacing the battery pack.
