Description

Technical Field

[0001] The present invention relates to the field of new energy vehicles, and in particular to a vehicle charging reservation system. Background Art

[0002] With the increasing attention paid to environmental protection and the adjustment of energy structure around the world, electric vehicles, as a green mode of travel, have been rapidly popularized in recent years. In order to improve the user experience of electric vehicle users and reduce charging costs, the appointment charging function has been continuously developed and improved. Car owners can conveniently set up appointment charging through mobile terminals and choose to charge during the period when electricity prices are low, which saves users money to a certain extent.

[0003] At present, there are two main methods in the market: AC scheduled charging and DC scheduled charging. However, AC scheduled charging is not enough for large-capacity electric equipment such as commercial vehicles and construction machinery with power requirements of more than 200-400kWh. Its general charging power of 7kW-11kW makes it take dozens of hours to charge such large-capacity equipment, which cannot meet actual needs. Although the DC scheduled charging method can theoretically better cope with the fast charging needs of large-capacity equipment, it currently mainly exists in setting up a scheduled charging function at the DC charging pile end. However, the reality is that the vast majority of DC charging piles on the market do not support the DC scheduled charging function, and the purchase and installation costs of DC piles are extremely expensive, usually costing 40,000-50,000 yuan. It is extremely rare to customize DC piles, which makes it difficult for electric car owners, especially those with large-capacity electric equipment, to charge at the DC charging pile through the scheduled charging function when the electricity price is low, resulting in high charging costs.

[0004] In addition, due to differences in charging standards in different countries, the charging control logic is also different. This makes it difficult for the existing scheduled charging methods on the market to be universal in different countries, and different versions of control methods need to be developed for different countries. This also makes it impossible to implement scheduled charging for vehicles in DC charging with existing technologies. Summary of the invention

[0005] The present invention provides a vehicle scheduled charging system, which can solve the problems of high cost and high charging cost of the existing vehicle scheduled charging system, and poor user charging experience caused by failure to complete vehicle scheduled charging in a DC state.

[0006] In a first aspect, an embodiment of the present invention provides a vehicle charging reservation system, the system comprising: a cloud platform end, a vehicle end and a charging pile;

[0007] The cloud platform is connected to the vehicle computer via a communication connection, and the vehicle computer is connected to the charging pile via a charging gun via a wired connection.

[0008] The cloud platform is used to generate a first reservation instruction and send it to the vehicle terminal after receiving the reservation charging information sent by the user and confirming that the current time point is later than the first reservation time point in the reservation charging information;

[0009] The vehicle terminal is used to check the charging gun status and battery status of the target vehicle in response to the received first reservation instruction, and when the charging gun status and battery status meet the preset standards, generate a trickle charging command and send it to the charging pile;

[0010] The charging pile is used to perform trickle charging on the target vehicle based on the trickle charging current in the trickle charging command when a trickle charging command is received.

[0011] Among them, the cloud platform end is also used to: before generating the first reservation instruction based on the current time point and the first reservation time point in the reservation charging information, determine whether the reception time of the reservation charging information is earlier than the first reservation time point in the reservation charging information; if so, generate a reservation success instruction and send it to the user; if not, generate a reservation failure instruction and send it to the user, and refuse to generate the first reservation instruction.

[0012] Furthermore, the cloud platform is also used to: continuously monitor the current time point, and when it is monitored that the current time point reaches the second scheduled time point in the scheduled charging information, generate a second reservation instruction and send it to the vehicle terminal.

[0013] Among them, the vehicle machine end is also used to: check the charging gun status and battery status of the target vehicle in response to the received second reservation instruction, and when the charging gun status and battery status meet the preset standards, generate a start charging command and send it to the charging pile.

[0014] Among them, the charging pile is also used to: when receiving a start charging command, charge the target vehicle according to a preset maximum charging current; the vehicle end is also used to: after generating a start charging command, monitor the battery status of the target vehicle in real time, and when it is monitored that the battery status is fully charged, generate an end charging instruction and send it to the charging pile, so that the charging pile terminates the charging operation in response to the end charging instruction.

[0015] Furthermore, the vehicle-mounted terminal specifically includes: a vehicle-mounted communication unit, a vehicle controller and a battery management unit connected in sequence; the vehicle-mounted communication unit is used to receive a first reservation instruction sent by the cloud platform and send it to the vehicle controller; the vehicle controller is used to detect the charging gun status and battery status of the target vehicle in response to the received first reservation instruction, and generate a first reservation flag according to the detection result and send it to the battery management unit; the battery management unit is used to generate a trickle charging command according to a preset trickle charging current after receiving the first reservation flag and send it to the charging pile.

[0016] Among them, the on-board communication unit is also used to: receive the second reservation instruction sent by the cloud platform and send it to the vehicle controller; the vehicle controller is also used to detect the charging gun status and battery status of the target vehicle in response to the received second reservation instruction, and generate a second reservation flag according to the detection result and send it to the battery management unit; the battery management unit is also used to generate a start charging command according to a preset maximum charging current after receiving the second reservation flag and send it to the charging pile, and monitor the battery status of the target vehicle in real time. When the battery status is monitored to be fully charged, a charging end instruction is generated and sent to the on-board communication unit; the on-board communication unit is used to send the received charging end instruction to the charging pile.

[0017] Optionally, the cloud platform is also used to: generate a second reservation instruction and send it to the vehicle computer in response to the reservation cancellation information sent by the user.

[0018] Furthermore, the vehicle controller specifically includes: a charging gun status detection unit, used to detect whether the charging gun status of the target vehicle is connected; a power detection unit, used to detect whether the battery power of the target vehicle is lower than a preset charging threshold; a command generation unit, used to generate a first reservation flag or a second reservation flag according to the current time point when it is detected that the charging gun status is connected and the battery power is lower than the preset charging threshold.

[0019] Specifically, the cloud platform is also used to: respond to a charging command sent by a user, detect that the current time point is earlier than the first scheduled time point in the scheduled charging information, generate a second reservation instruction and send it to the vehicle terminal.

[0020] The technical solution of the embodiment of the present invention is that after receiving the scheduled charging information sent by the user, the cloud platform side confirms that the current time point is later than the first scheduled time point in the scheduled charging information, generates a first reservation instruction and sends it to the vehicle side, and then the vehicle side responds to the received first reservation instruction to check the charging gun status and battery status of the target vehicle. When the charging gun status and the battery status both meet the preset standards, a trickle charging command is generated and sent to the charging pile. Finally, when the charging pile receives the trickle charging command, the target vehicle is trickle charged based on the trickle charging current in the trickle charging command. The problem of high cost and high charging cost of the existing vehicle scheduled charging system and poor user charging experience caused by the inability to complete the vehicle scheduled charging in the DC state is solved, and the vehicle scheduled charging of the DC charging pile is realized, which reduces the user's charging cost and improves the user's charging experience.

[0027] Embodiment 1

[0028] Figure 1 This is a schematic diagram of the structure of a vehicle charging reservation system provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of reserving vehicle charging operations at a DC charging pile.

[0029] like Figure 1 As shown, the system includes: a cloud platform end 110, a vehicle machine end 120 and a charging pile 130.

[0030] The cloud platform end 110 is communicatively connected with the vehicle end 120 , and the vehicle end 120 is wiredly connected with the charging pile 130 via a charging gun.

[0031] In this embodiment, the charging pile 130 may specifically be a vehicle charging device capable of providing a DC charging service for a vehicle.

[0032] The cloud platform end 110 is used to generate a first reservation instruction and send it to the vehicle end 120 after receiving the reservation charging information sent by the user and confirming that the current time point is later than the first reservation time point in the reservation charging information.

[0033] Exemplarily, the cloud platform end 110 is used to accurately compare and confirm the current time point with the first scheduled time point set in the scheduled charging information immediately after receiving the scheduled charging information sent by the user through relevant channels (such as mobile phone APP, web page, etc.). The scheduled charging information here refers to the detailed content set by the user, including the specific time when the charging is expected to start, the charging duration, the charging power, etc. The specific setting content can be set by the developer according to the actual implementation scenario, and this embodiment does not limit this; wherein, the first scheduled time point is the starting time when the user expects to start the scheduled charging process; it should be noted that only when the premise that the current time point is indeed later than the first scheduled time point clearly specified in the scheduled charging information is met, the cloud platform end 110 will generate the first reservation instruction, and send it accurately to the vehicle end 120 through the preset communication method (such as 5G network, Bluetooth, etc.) to start the subsequent scheduled charging process.

[0034] Furthermore, the cloud platform end 110 is also used to: before generating the first reservation instruction based on the current time point and the first reservation time point in the reservation charging information, determine whether the reception time of the reservation charging information is earlier than the first reservation time point in the reservation charging information; if so, generate a reservation success instruction and send it to the user; if not, generate a reservation failure instruction and send it to the user, and refuse to generate the first reservation instruction.

[0035] Exemplarily, before generating the first reservation instruction according to the current time point and the first reservation time point in the reservation charging information, the cloud platform end 110 will determine whether the reception time of the reservation charging information is earlier than the first reservation time point in the reservation charging information; wherein, the reservation charging information includes a series of detailed contents such as the specific time when the user starts charging (such as 10 o'clock in the evening), the expected charging time (such as 3 hours), and the expected charging power (such as 80%). If it is determined that the reception time of the reservation charging information is earlier than the first reservation time point, the cloud platform end 110 will quickly generate a reservation success instruction and send it to the user in time to let the user know that the reservation has been successful. However, if it is determined that the reception time of the reservation charging information is later than the first reservation time point, the cloud platform end 110 will generate a reservation failure instruction and send it to the user in a timely manner, and refuse to generate the first reservation instruction. This means that the user's reservation this time fails to meet the conditions set by the system and the reservation charging operation cannot be performed as expected.

[0036] Furthermore, the cloud platform end 110 is also used to: continuously monitor the current time point, and when it is monitored that the current time point reaches the second scheduled time point in the scheduled charging information, generate a second reservation instruction and send it to the vehicle end 120.

[0037] Optionally, the cloud platform end 110 is also used to: generate a second reservation instruction and send it to the vehicle end 120 in response to the reservation cancellation information sent by the user.

[0038] Optionally, the cloud platform end 110 is also used to: respond to a charging command sent by a user, after detecting that the current time point is earlier than the first scheduled time point in the scheduled charging information, generate a second reservation instruction and send it to the vehicle end 120.

[0039] Specifically, the cloud platform end 110 also has the following functions: first, the current time point is continuously and closely monitored. And once it is detected that the current time point has reached the second scheduled time point set in the scheduled charging information, a second reservation instruction will be immediately generated and then sent to the vehicle end 120. Among them, the second scheduled time point is the time point set by the user to start charging the vehicle formally; second, the cloud platform end 110 is also used to quickly generate a second reservation instruction and send it to the vehicle end 120 after receiving the reservation cancellation information sent by the user through a mobile phone APP or a web page, wherein the reservation cancellation information refers to the user's request to cancel the scheduled charging due to a change in the itinerary, etc.; third, the cloud platform end 110 is also used to respond to the charging command sent by the user through the in-vehicle button or mobile phone APP. If it is detected that the current time point is earlier than the first scheduled time point in the scheduled charging information, it will also generate a second reservation instruction and send it to the vehicle end 120. The charging command is an instruction issued by the user to start charging immediately.

[0040] The vehicle terminal 120 is used to check the charging gun status and battery status of the target vehicle in response to the received first reservation instruction, and when the charging gun status and battery status meet the preset standards, generate a trickle charging command and send it to the charging pile 130.

[0041] Specifically, in response to the received first reservation instruction, the vehicle terminal 120 will conduct a comprehensive and detailed inspection of the charging gun status and battery status of the target vehicle. The charging gun status here refers to whether the connection between the charging gun and the vehicle charging interface is stable, loose or poorly connected; the battery status includes the remaining battery power, battery temperature, battery health and other aspects. The preset standards, for example, stipulate that the charging gun must be firmly connected without signs of looseness, the remaining battery power is below a certain threshold, the battery temperature is within a safe range, and the battery is in good health; further, after checking to determine that the charging gun status and the battery status meet the above preset standards, the vehicle terminal 120 will generate a trickle charging command and send it accurately to the charging pile 130 through wired communication; trickle charging is a method of slowly charging the battery with a smaller current, such as charging with a current of 1A-2A. Relevant personnel in this field should understand that due to the characteristics of the DC charging pile 130, if there is no power output for a long time, it will automatically enter a sleep state. In this embodiment, the problem of the DC charging pile 130 entering sleep due to no current output for a long time is solved by setting a trickle charging method; it should be noted that the trickle charging current requirement is pre-set to a very small value to ensure that the battery replenishment does not exceed 5% within the scheduled time.

[0042] Among them, the vehicle terminal 120 is also used to: check the charging gun status and battery status of the target vehicle in response to the received second reservation instruction, and when the charging gun status and battery status meet the preset standards, generate a start charging command and send it to the charging pile 130.

[0043] In this embodiment, illustratively, the vehicle terminal 120 will quickly and carefully conduct a strict inspection of the charging gun status and battery status of the target vehicle in response to the received second reservation instruction. The charging gun status mentioned here specifically refers to whether the physical connection between the charging gun and the vehicle charging interface is tight and stable, and whether there are any abnormal conditions such as looseness, falling off or poor contact. The battery status covers multiple key aspects such as the remaining power value of the battery (for example, 20% of the remaining power), the current temperature of the battery (for example, 30 degrees Celsius), and the health of the battery (such as the number of cycles of the battery, the size of the internal resistance, and other indicators reflecting the health status). The preset standard, for example, clearly stipulates that the charging gun must be tightly and firmly connected, without any signs of looseness, and the remaining power of the battery is lower than a specific threshold (for example, 30%), the battery temperature is in a safe range (for example, 0-50 degrees Celsius), and the battery health is good (for example, the number of battery cycles does not exceed the specified upper limit, and the internal resistance is within the normal range). After careful and rigorous inspection, when it is determined that the status of the charging gun and the battery fully meet the above preset standards, the vehicle terminal 120 will generate a command to start charging and send it to the charging pile 130 in a timely manner through a stable and efficient communication method.

[0044] The charging pile 130 is used to perform trickle charging on the target vehicle based on the trickle charging current in the trickle charging command when receiving the trickle charging command.

[0045] Furthermore, the charging pile 130 is also used to: when receiving a start charging command, charge the target vehicle according to a preset maximum charging current; the vehicle terminal 120 is also used to: after generating a start charging command, monitor the battery status of the target vehicle in real time, and when monitoring that the battery status is fully charged, generate an end charging instruction and send it to the charging pile 130, so that the charging pile 130 terminates the charging operation in response to the end charging instruction.

[0046] Specifically, upon receiving the start charging command, the charging pile 130 will strictly charge the target vehicle according to the preset maximum charging current. The preset maximum charging current mentioned here can be a current upper limit value set according to the specifications of the vehicle battery and the capacity of the charging equipment, such as 30A. The maximum charging current can increase the charging speed as much as possible under the premise of ensuring charging safety; further, the vehicle terminal 120 is also used to: after generating the start charging command, it will monitor the battery status of the target vehicle in real time through built-in sensors and related monitoring equipment. The battery status here includes the real-time power level of the battery (for example, it has been charged to 80%), the temperature change inside the battery (for example, from 25 degrees Celsius to 35 degrees Celsius), the voltage of the battery, etc. In addition, when it is monitored that the battery status reaches the full power state, the vehicle terminal 120 will generate an end charging instruction and send it to the charging pile 130. The full power state can be judged by the battery power reaching 100% of its rated capacity or the battery voltage reaching a specific upper limit value. After receiving the end-charging instruction, the charging station 130 will respond immediately and terminate the current charging operation to avoid damage to the battery due to overcharging.

[0047] The technical solution of the embodiment of the present invention is that after the cloud platform receives the scheduled charging information sent by the user, when it confirms that the current time point is later than the first scheduled time point in the scheduled charging information, a first reservation instruction is generated and sent to the vehicle computer end, and then the vehicle computer end responds to the received first reservation instruction to check the charging gun status and battery status of the target vehicle. When the charging gun status and the battery status both meet the preset standards, a trickle charging command is generated and sent to the charging pile. Finally, when the charging pile receives the trickle charging command, the target vehicle is trickle charged based on the trickle charging current in the trickle charging command, thereby realizing vehicle scheduled charging of the DC charging pile, reducing the user's charging cost, and improving the user's charging experience.

[0048] Embodiment 2

[0049] Figure 2 This is a schematic diagram of the structure of a vehicle charging reservation system provided in Embodiment 2 of the present invention. This embodiment is applicable to the case of reserving vehicle charging operations at a DC charging pile.

[0050] like Figure 2 As shown, the system includes: a cloud platform, a vehicle computer and a charging pile.

[0051] The vehicle terminal specifically includes: a vehicle communication unit 210, a vehicle controller 220 and a battery management unit 230 connected in sequence;

[0052] The vehicle-mounted communication unit 210 is used to receive the first reservation instruction sent by the cloud platform and send it to the vehicle controller 220.

[0053] Furthermore, the vehicle-mounted communication unit 210 is also used to: receive a second reservation instruction sent by the cloud platform and send it to the vehicle controller 220; the vehicle controller 220 is also used to detect the charging gun status and battery status of the target vehicle in response to the received second reservation instruction, and generate a second reservation flag according to the detection result and send it to the battery management unit 230; the battery management unit 230 is also used to generate a start charging command according to a preset maximum charging current after receiving the second reservation flag and send it to the charging pile, and monitor the battery status of the target vehicle in real time, and when the battery status is detected to be fully charged, generate an end charging instruction and send it to the vehicle-mounted communication unit 210; the vehicle-mounted communication unit 210 is used to send the received end charging instruction to the charging pile.

[0054] Among them, the vehicle-mounted communication unit 210 is a module responsible for communicating and interacting with the outside, such as establishing a connection with the cloud platform end through Bluetooth, wireless network, etc. Its main function is to receive the first reservation instruction sent by the cloud platform end and send it to the vehicle controller 220 accurately; further, the vehicle-mounted communication unit 210 is also used to receive the second reservation instruction sent by the cloud platform end and pass it to the vehicle controller 220. The vehicle controller 220 is the core control unit of the vehicle end. After receiving the second reservation instruction, it will conduct a comprehensive detection of the charging gun status and battery status of the target vehicle. The charging gun status includes whether the charging gun is firmly connected and whether it is damaged; the battery status covers the remaining battery power, battery temperature, battery health status, etc. Then, the vehicle controller 220 will generate a second reservation flag based on the detection results and send it to the battery management unit 230.

[0055] Furthermore, the battery management unit 230 is mainly responsible for managing and monitoring the charging and discharging of the battery. After receiving the first reservation flag, a trickle charging command is generated according to the preset trickle charging current and sent to the charging pile, and when the second reservation flag is received, a start charging command is generated and sent to the charging pile according to the preset maximum charging current, such as a 50A current set according to the specifications of the vehicle battery and the safety charging requirements. At the same time, the battery management unit 230 will monitor the battery status of the target vehicle in real time, such as obtaining the battery power, temperature and other data once a second. Once it is detected that the battery status is fully charged, that is, the battery power reaches 100% of its rated capacity or the battery voltage reaches the preset upper limit, a charge termination instruction will be generated and sent to the vehicle communication unit 210. Finally, the vehicle communication unit 210 will send the received charge termination instruction to the charging pile in a timely manner, thereby controlling the charging pile to terminate the charging operation.

[0056] The vehicle controller 220 is used to detect the charging gun status and battery status of the target vehicle in response to the received first reservation instruction, and generate a first reservation flag according to the detection result and send it to the battery management unit 230.

[0057] Among them, the whole vehicle controller 220 specifically includes: a charging gun status detection unit, used to detect whether the charging gun status of the target vehicle is connected; a power detection unit, used to detect whether the battery power of the target vehicle is lower than a preset charging threshold; a command generation unit, used to generate a first reservation flag or a second reservation flag according to the current time point when it is detected that the charging gun status is connected and the battery power is lower than the preset charging threshold.

[0058] Specifically, the vehicle controller 220 is used to respond to the received first reservation instruction and use the internal detection mechanism to comprehensively and accurately detect the charging gun status and battery status of the target vehicle; wherein, the vehicle controller 220 specifically includes: a charging gun status detection unit, which is specifically responsible for detecting whether the charging gun status of the target vehicle is connected, for example, detecting whether the physical connection between the charging gun and the vehicle charging interface is tight, whether the plug is fully inserted, etc. through a sensor. It should be noted that the method of detecting the charging gun status through the vehicle controller 220 is a mature existing technology, and the principle thereof is not elaborated in this embodiment; further, the power detection unit is used to detect whether the battery power of the target vehicle is lower than a preset charging threshold, wherein the preset charging threshold can be a value set according to the vehicle battery characteristics and user needs, such as the battery power is lower than 20%. The command generation unit will function when it detects that the charging gun is connected and the battery power is lower than the preset charging threshold. It will generate the first reservation flag or the second reservation flag according to the current time point. For example, if the current time is 10 o'clock in the evening and the user sets the scheduled charging time to 11 o'clock in the evening, the first reservation flag will be generated when it is detected that 11 o'clock has arrived; if the current time has exceeded the scheduled charging time set by the user, the second reservation flag will be generated. These flags will be sent to the battery management unit 230 to trigger the subsequent corresponding charging operations.

[0059] The technical solution of the embodiment of the present invention is that after the cloud platform receives the scheduled charging information sent by the user, when it confirms that the current time point is later than the first scheduled time point in the scheduled charging information, a first reservation instruction is generated and sent to the vehicle computer end, and then the vehicle computer end responds to the received first reservation instruction to check the charging gun status and battery status of the target vehicle. When the charging gun status and the battery status both meet the preset standards, a trickle charging command is generated and sent to the charging pile. Finally, when the charging pile receives the trickle charging command, the target vehicle is trickle charged based on the trickle charging current in the trickle charging command, thereby realizing vehicle scheduled charging of the DC charging pile, reducing the user's charging cost, and improving the user's charging experience.

[0060] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.
