Example 1

Referring to fig. 1 to 3, a charging system for a charging and replacing power station according to the present application is described with reference to a container type charging and replacing power station. Fig. 1 is a system structure diagram of a charging system for a charging and replacing power station according to the present application; fig. 2 is an exploded view of the container type charging and replacing station of the present application; fig. 3 is a system structure diagram of a user interaction device of a battery swapping system for a battery charging and swapping station according to the present application.

As shown in fig. 1, in order to solve the problem of poor battery replacement experience caused by equipment failure in the battery replacement process of an unattended battery charging and replacing station, the battery replacement system for a container type battery charging and replacing station (hereinafter, referred to as a battery charging and replacing station or a battery replacing station) mainly comprises an electric control host, a battery replacement device 2 and a user interaction device 3. The power swapping device 2 and the user interaction device 3 are respectively in communication connection with the in-station host 1, the in-station host 1 is configured to be capable of responding to a received automatic power swapping instruction and controlling the power swapping device 2 to replace a power battery for the vehicle 4 to be swapped parked at a preset power swapping position, the user interaction device 3 is configured to be capable of responding to the received manual power swapping instruction and sending a manual power swapping action signal to the in-station host 1, and the in-station host 1 is further configured to be capable of responding to the received manual power swapping action signal and controlling the power swapping device 2 to execute a power swapping action corresponding to the manual power swapping action signal.

In a possible implementation mode, when the battery replacement is needed, a user stops the vehicle 4 to be replaced at a preset battery replacement position, and sends an automatic battery replacement command to the electronic control host through the user interaction device 3, and the electronic control host controls the battery replacement device 2 to replace the power battery for the vehicle 4 to be replaced after receiving the automatic battery replacement command. The battery replacement process is fully automatically executed, and a user only needs to wait for the battery to be replaced and then directly drive the vehicle away. In the battery replacement process, if a battery replacement interruption occurs due to a fault of the battery replacement station, a user may send a manual battery replacement command by operating the user interaction device 3, the user interaction device 3 sends a manual battery replacement signal to the in-station host 1 after receiving the manual battery replacement command, and after receiving the manual battery replacement signal, the in-station host 1 controls the battery replacement device 2 to execute a battery replacement action corresponding to the manual battery replacement signal, for example, to continue to execute the remaining battery replacement action or to execute only one or more of the following actions: removing the power battery that is under-charged, transporting the power battery that is under-charged to the battery rack 21, receiving the power battery that is fully charged from the battery rack 21 and transporting it under the vehicle 4 to be replaced, and mounting the power battery that is fully charged to the vehicle 4 to be replaced.

It can be seen that, by arranging the user interaction device 3 in the battery charging and replacing station, when an equipment fault occurs in the battery replacing process, a user can indirectly control the battery replacing device 2 to execute the battery replacing action through the user interaction device 3 without the help of an attended specialist so as to complete the replacement of the vehicle power battery, the battery replacing experience of the user is improved, and the problem that the user travel plan is influenced by the fact that a user vehicle is placed in the battery charging and replacing station due to the occurrence of the equipment fault in the battery replacing process is solved.

Referring to fig. 1 to 3, a preferred embodiment of the battery swapping system of the present application will be described.

Referring to fig. 2, in one possible embodiment, the container type charging and replacing power station of the present application includes a box body 6, and an in-station host 1 and a replacing power device 2 which are arranged in the box body 6. The battery replacing device 2 comprises a battery frame 21, a parking platform 22, a battery transferring mechanism, a battery lifting mechanism, a locking and unlocking mechanism and the like. The box body 6 is mainly divided into two parts, one part is mainly used for arranging the parking platform 22, and the other part is mainly used for arranging the main machine 1, the battery rack 21 and the like in the station. An inlet and outlet 61 is formed on one side surface of the box 6 corresponding to the parking platform 22 for the vehicle 4 to be changed to enter or exit the parking platform 22. The parking platform 22 is used for positioning the vehicle 4 to be replaced, such as front-back positioning and left-right centering positioning (with the vehicle advancing direction as a reference) of the vehicle 4 to be replaced, and when the vehicle 4 to be replaced is parked on the parking platform 22, the power battery of the vehicle 4 to be replaced can be replaced from the lower side of the vehicle 4 to be replaced. A plurality of storage positions for storing power batteries are arranged in the battery frame 21, and when the power batteries are located at the storage positions, the battery frame 21 can charge the power batteries. The battery transfer mechanism is used for transferring batteries between the battery rack 21 and the parking platform 22, and the battery lifting mechanism is used for taking and placing power batteries from different positions of the battery rack 21. The battery transfer mechanism can be a conveyor belt or a battery replacement robot. When the battery transfer mechanism is a conveyor belt, a battery lifting mechanism and an unlocking mechanism can be arranged on the parking platform 22 to realize the dismounting and mounting of the power battery, and when the battery transfer mechanism is a battery replacing robot, the lifting mechanism and the unlocking mechanism arranged on the battery replacing robot can realize the dismounting and mounting of the power battery.

The in-station host 1 is used as an upper computer for logic processing of the whole station, and is in communication connection with each mechanism in the battery swapping device 2, for example, the in-station host is connected in a wired manner through an ethernet bus, a CAN bus, an RS-485 bus and the like, or is connected in a wireless manner through WiFi, bluetooth and the like. The in-station host 1 can issue a control instruction to the industrial control modules (such as PLC) of the motion mechanisms, so that the industrial control modules control the corresponding mechanisms to execute predetermined actions. For example, the in-station host 1 sends a control instruction to the industrial control module of the parking platform 22, and the industrial control module of the parking platform 22 controls the centering motor to rotate to drive the push rod to push the wheels to translate so as to realize centering operation of the electric vehicle 4 to be replaced; for another example, the in-station host 1 sends a control instruction to an industrial control module of the locking and unlocking mechanism, and the industrial control module of the locking and unlocking mechanism controls the locking and unlocking motor to rotate to drive the locking and unlocking head to rotate so as to lock and unlock the locking device of the power battery; for another example, the host 1 sends a control instruction to the industrial control module of the battery transfer mechanism, and the industrial control module of the battery transfer mechanism controls the roller motor to rotate to realize that the roller way transfers the insufficient-voltage battery to the battery lifting mechanism and the like. The principle that the in-station host 1 of the charging and swapping station controls the actions of the mechanisms to realize swapping is common knowledge in the field, and is not described herein again.

Of course, the specific composition of the charging and replacing station is not limited in the present application, and any form of charging and replacing station can replace the charging and replacing station on the premise that the charging and replacing device 2 is controlled by the in-station host 1 to replace the electric vehicle 4 to be replaced, and the replacement does not deviate from the principle of the present application.

Besides, in addition to the communication connection with the battery swapping device 2, the in-station host 1 can also be in communication connection with the vehicle 4 to be swapped, receive authentication information sent by the vehicle 4 to be swapped, and authenticate the vehicle 4 to be swapped based on the authentication information. For example, the in-station host 1 may be connected to the vehicle 4 to be replaced by WiFi, bluetooth, lan, 3G/4G/5G, and the like, when the vehicle enters a preset range of the charging and replacing station, the vehicle is in communication with the in-station host 1, and sends authentication information of the vehicle, such as a license plate number, a vehicle identification code, and the like, to the in-station host 1, and the in-station host 1 authenticates the vehicle 4 to be replaced according to the received authentication information and pre-stored vehicle order information, and determines whether the vehicle 4 to be replaced has placed an order for replacing the battery. And when the authentication is passed, the vehicle is proved to be capable of replacing the battery, otherwise, the vehicle is not capable of replacing the battery.

It should be noted that the specific principle of the communication connection between the in-station host 1 and the to-be-switched vehicle 4 and the specific principle of the authentication are commonly used in the art, and are not described herein again. The authentication method is not limited in the present application, and the above-described specific authentication method is merely exemplary, and any method that can authenticate the in-station host 1 and the to-be-replaced vehicle 4 may be applied to the present application on the premise that the in-station host 1 and the to-be-replaced vehicle 4 are communicatively connected.

Further, in a possible implementation manner, in order to implement monitoring on the battery charging and replacing process, the battery replacing system further includes a collecting component, the collecting component is connected with the in-station host 1 and configured to be capable of collecting the operation parameters of the battery replacing device 2 and sending the operation parameters to the in-station host 1, and the in-station host 1 is further capable of judging whether the battery charging and replacing station has a fault according to the operation parameters and selectively sending a fault signal to the user interaction device 3 according to a judgment result. The operation parameters of the power exchanging device 2 include, but are not limited to, a movement speed, a rotation speed, a torque, a position, a temperature, a humidity, a smoke concentration, and the like.

For example, to monitor the power battery on the battery rack 21, a temperature sensor, a humidity sensor, a smoke sensor, and the like may be provided to monitor the temperature and humidity of the power battery and the smoke nearby. In order to realize the monitoring of the locking and unlocking mechanism, a position sensor, a speed sensor, a torque sensor and the like can be arranged to monitor the rotating speed of a driving motor of the locking and unlocking mechanism, the position of a locking and unlocking head, the torque and other parameters. In order to monitor the state of the vehicle 4 to be replaced and the safety of the battery replacing process, a distance sensor, a camera and the like may be arranged near the parking platform 22 to monitor the position of the vehicle 4 to be replaced, whether a person is present on the parking platform 22 or not.

The in-station host 1 can judge whether the power exchanging device 2 has a fault through the acquired motion parameters, and send a fault signal to the user interaction device 3 in time when the fault exists. Taking the locking and unlocking mechanism as an example, in the power exchanging process, the in-station host 1 judges whether the motion state of the locking and unlocking mechanism is normal or not through the received operation parameters of the locking and unlocking mechanism, such as the position and the torque of the locking and unlocking head, the speed of a motor transmission shaft and the like, and through the comparison of the torque, the speed and the position with preset values, judges that the locking and unlocking mechanism has a fault when any operation parameter deviates from the preset value, and sends a fault signal to the user interaction device 3. If the torque is larger than the preset torque value, the system can diagnose that the locking and unlocking head is stuck and the like. Taking the parking platform 22 as an example, in the battery replacement process, the in-station host 1 receives a video or an image acquired by a camera, judges the safety of the battery replacement process based on an image analysis result, and when a person appears in a battery replacement forbidden area (an area which is not suitable for being detained during battery replacement) based on the image analysis, judges that the parking platform 22 has a fault and sends a fault signal to the user interaction device 3.

Through setting up the collection subassembly for in-station host computer 1 can judge whether there is the trouble in the power station of charging based on the operating parameter that the collection subassembly was gathered, and in time send trouble signal to display screen main part 31 when breaking down, so that in time inform the user with trouble information and countermeasure through display screen main part 31.

The sound pickup part 33 may be a microphone or a sound pickup, which is connected to the control main board and is capable of sending the received voice information to the control main board, and the control main board is further capable of recognizing the voice information and sending an instruction signal to the in-station host 1 based on the recognition result.

For example, after the host 1 in the station authenticates and authenticates the battery replacement vehicle 4, the authentication passing signal may be sent to the control main board of the user interaction device 3, and then the control main board controls the touch screen to display text prompt information, and controls the sound box 32 to send out voice prompt information to prompt the user that the authentication passes, so that battery replacement may be performed, and a "start battery replacement" button is displayed in a specific area of the touch screen. When a user presses a button for starting battery replacement or confirms battery replacement by sending voice, the control main board sends an automatic battery replacement instruction to the in-station host 1 after acquiring a confirmation instruction that the touch screen is pressed or acquiring a confirmation battery replacement instruction by voice recognition.

For another example, in the automatic power swapping process, the in-station host 1 sends a display step instruction to the control main board based on the collected information based on the power swapping step, and the control main board controls the touch screen to display a demonstration animation of the currently executed power swapping step after receiving the instruction.

For another example, when the in-station host 1 determines that the power charging and switching station has a fault based on the collected motion parameters, the in-station host 1 sends a fault signal to the control main board based on the fault type, the control main board displays the fault existing in the current power charging and switching station after receiving the fault signal, and simultaneously gives a solution prompt, for example, a method for removing the fault is given for a simpler fault (for example, a fault which does not affect the operation of the power switching device 2 such as shielding of a sensor and alarm in a forbidden area, and can realize continuous power switching through human intervention after the fault is eliminated), and a staff contact mode is given for a more complex fault (for example, a fault which affects the operation of the power switching device 2 such as damage of a driving motor and fracture of a transmission shaft). When a fault removing method is given, a 'continue battery changing' button can be displayed on a specific area of the touch screen at the same time, when a user presses the 'continue battery changing' button, the main board is controlled to acquire a command for continuing battery changing and send the command for continuing battery changing to the in-station host 1, the in-station host 1 judges whether the fault is removed or not based on the command, and the residual battery changing process is continuously executed or only part of battery changing actions are executed when the fault is removed. When the contact way of the staff is given, a button for contacting the staff can be given on the touch screen at the same time, and after a user presses the button for contacting the staff, the control main board obtains an instruction for contacting the staff and calls the appointed staff through a communication module arranged by the control main board or calls the appointed staff through network communication software installed by the control main board.

Of course, the user interaction device 3 is only a preferred embodiment, and those skilled in the art can adjust the specific components thereof to suit more specific application scenarios. For example, in other embodiments, the user interaction apparatus 3 may only include the display screen main body 31, or may only include the sound 32 and the sound pickup part 33, and the sound 32 and the sound pickup part 33 may be integrated with the display screen main body 31, or may be provided separately from the display screen main body 31, or may replace the touch screen or the like by a non-touch display screen and buttons combination method. As another example, the setting position of the user interaction device 3 is not exclusive, but it may be set at other positions as long as the position is convenient for the user to view and use.
