[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] The charging device usually includes a main processor chip and multiple slave processor chips. The main processor chip and the slave processor chips cooperate with each other to complete the charging of the new energy vehicle. After the charging device is powered on, the main processor chip and the slave processor chip will be in a working state all the time, resulting in increased power consumption and excessive temperature of the processor chip. The processor chip being in a working state for a long time may also expose stability problems, such as freezing problems, electromagnetic interference causing the chip to fail to operate normally, etc. Based on this, the embodiment of the present application proposes a charging device, including: a main processor chip, multiple slave processor chips, and multiple relays corresponding to the multiple slave processor chips respectively; the main processor chip is connected to the multiple relays, and each relay is connected between the corresponding slave processor and the power supply; the main processor chip is used to: enter the normal working mode when receiving the charging instruction for the current vehicle, and control the power-on of multiple slave processor chips through multiple relays; the main processor chip is also used to: enter the low-power working mode when determining that the current vehicle is finished charging, and control the power-off of multiple slave processor chips through multiple relays. The power consumption and temperature of the processor chip can be reduced, and the stability problems caused by the processor chip being in a working state for a long time can be reduced.

[0024] The charging device provided in the embodiment of the present application can be used to charge any vehicle that can be driven by electricity, such as a pure electric vehicle, a hybrid electric vehicle, etc., which is not limited in the embodiment of the present application. The above charging device is described below in conjunction with a specific embodiment.

[0025] In an exemplary embodiment, Figure 1 As shown, a charging device is provided, including a main processor chip, multiple slave processor chips and multiple relays corresponding to the multiple slave processor chips respectively; the main processor chip is connected to the multiple relays, and each relay is connected between the corresponding slave processor and the power supply; the main processor chip is used to: enter the normal working mode when receiving the charging instruction for the current vehicle, and control the power-on of the multiple slave processor chips through the multiple relays; the main processor chip is also used to: enter the low power consumption working mode when it is determined that the charging of the current vehicle is completed, and control the power-off of the multiple slave processor chips through the multiple relays.

[0026] Optionally, the main processor chip can be a microprocessor, a central processing unit (CPU), a microprocessor, a microcomputer, a single-chip microcomputer, etc.; similarly, the slave processor chip can also be a microprocessor, a central processing unit (CPU), a microprocessor, a microcomputer, a single-chip microcomputer, etc., and the embodiments of the present application are not limited to this.

[0027] Optionally, the main processor chip has a built-in corresponding program code, and each slave processor chip also has a built-in corresponding program code. When the main processor chip is in a normal working state, all its built-in program codes are in a normal working state. After the slave processor chip is powered on, all its built-in program codes are in a normal working state. After receiving the charging instruction for the current vehicle, the main processor chip cooperates with each slave processor chip to complete the charging of the current vehicle. The functions of the main processor chip and the slave processor chip and the process of mutual cooperation can be referred to the relevant introduction of the existing charging pile.

[0028] Optionally, the relay is an automatic switching element with an isolation function, and the relay may be a micro relay, an ultra-small micro relay, a small micro relay, etc., which is not limited in the embodiments of the present application.

[0029] The number of slave processor chips and relays is the same, and each slave processor chip corresponds to a relay. Each relay is connected between the corresponding slave processor and the power supply; the master processor chip is connected to multiple relays.

[0030] Since, when the charging device is in a standby state, that is, when it is not charging externally, some functions of the main processor chip are not used, and the functions of the slave processor chips are also not used. In order to save the power consumption of each processor chip, the unused functions in the main processor chip can be turned off, and each slave processor chip can be directly powered off, which can greatly reduce the power consumption of each processor chip, reduce the possibility of excessive heating caused by excessive operation of the processor chip, and reduce the possibility of the processor chip exposing stability problems. When the main processor chip receives the charging instruction for the current vehicle, it turns on the above-mentioned turned-off functions and powers on each slave processor chip, so that the program codes built into the main processor chip and each slave processor chip can run normally, so that the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0031] Optionally, the main processor chip can turn on all functions upon receiving a charging instruction for the current vehicle, that is, control all its built-in program codes to run normally. At this time, the main processor chip enters a normal working mode. On the other hand, the main processor chip can also control all relays to turn on. At this time, the circuits between all slave processor chips and the power supply are turned on, and the power supply can normally supply power to each slave processor chip, that is, each slave processor chip is powered on. After each slave processor chip is powered on, all its built-in program codes are controlled to run normally. After the user inserts the charging gun into the charging port of the current vehicle, the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0032] When the main processor chip determines that the charging of the current vehicle is finished, it can turn off the unused functions of the charging device when it is in the idle state, that is, the program codes corresponding to these functions stop running. At this time, the main processor chip enters a low-power working state, reducing the power consumption of the main processor chip. On the other hand, the main processor chip can also control all relays to be disconnected. At this time, the power supply cannot supply power to each slave processor chip, that is, each slave processor chip is powered off. Since each slave processor chip is powered off, all the built-in program codes can no longer run. The power consumption of each slave processor chip is reduced. The above method can reduce the possibility of excessive heating caused by excessive operation of each processor chip, and can also reduce the possibility of each processor chip exposing stability problems.

[0033] Exemplarily, the main processing chip is connected to the plurality of relays respectively through the general purpose input and output ports GPIO.

[0034] In the above embodiment, a charging device is provided, including a main processor chip, a plurality of slave processor chips, and a plurality of relays corresponding to the plurality of slave processor chips; the main processor chip is connected to the plurality of relays, and each relay is connected between the corresponding slave processor and the power supply; the main processor chip is used to: enter the normal working mode when receiving the charging instruction for the current vehicle, and control the power-on of the plurality of slave processor chips through the plurality of relays; the main processor chip is also used to: enter the low power working mode when determining that the charging of the current vehicle is finished, and control the power-off of the plurality of slave processor chips through the plurality of relays. The power consumption of each processor chip is reduced, the possibility of the processor chip heating up too fast due to excessive operation is reduced, and the possibility of the processor chip exposing stability problems is also reduced.

[0035] In some embodiments, see Figure 2 As shown, the charging device also includes an RFID card reader, which is connected to the main processor chip via a serial communication interface RS232. The RFID card reader is used to read a user identification card and send the read card information to the main processor chip. The main processor chip uses the card information as a charging instruction for the current vehicle.

[0036] The user identification card may be a charging card applied for by the user, and the user identification card stores a card identification number, user identification information, etc., which are referred to as card information in the embodiment of the present application. The user may place the user identification card at a designated position of the RFID card reader, and the RFID card reader may read the card information stored in the user identification card, and the RFID card reader may send the read card information to the main processor chip.

[0037] Optionally, after receiving the card information, the main processor chip can obtain the user's balance based on the card information and determine whether the balance meets the charging conditions. If the charging conditions are met, the card information is used as a charging instruction for the current vehicle, and all its functions are turned on, that is, all its built-in program codes are controlled to run normally. At this time, the main processor chip enters the normal working mode. The main processor chip can also control all relays to be turned on. At this time, the circuits between all slave processor chips and the power supply are turned on, and the power supply can normally supply power to each slave processor chip, that is, each slave processor chip is powered on. After each slave processor chip is powered on, all its built-in program codes are controlled to run normally. After the user inserts the charging gun into the charging port of the current vehicle, the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0038] If the charging condition is not met, the main processor chip may send an insufficient balance prompt to the display device, and the display device may display the insufficient balance prompt to remind the user that the balance of the user identification card used by the user is insufficient.

[0039] Optionally, the charging condition may be that the balance is greater than a preset threshold, the balance is greater than the cost of one charge, etc. The charging condition may be flexibly set according to actual conditions, and the embodiments of the present application do not limit this.

[0040] It should be noted that the above balance verification is only an example, and other information can also be verified. If the verification passes, the card information is used as a charging instruction for the current vehicle; if the verification fails, the main processor chip can send a verification failure prompt to the display device, and the display device can display the verification failure prompt to remind the user that the user identification card used by the user has failed the verification. Alternatively, the main processor chip can also omit the verification step and directly use the card information as a charging instruction for the current vehicle after receiving the card information.

[0041] In the above embodiment, the user can place the user identification card at the designated position of the RFID card reader, and the RFID card reader can read the card information stored in the user identification card, and the RFID card reader can send the read card information to the main processor chip. After receiving the card information, the main processor chip uses the card information as a charging instruction for the current vehicle, enters the normal working mode, and controls the power-on of multiple slave processor chips through multiple relays; so that after the user inserts the charging gun into the charging port of the current vehicle, the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0042] In some embodiments, see Figure 3 As shown, the charging device also includes a point-of-sale (POS) machine, which is connected to the main processor chip via a serial communication interface RS232. The POS machine is used to read a bank card and send the read card information to the main processor chip, which uses the card information as a charging instruction for the current vehicle.

[0043] Among them, the bank card can be a bank card bound to a charging consumption function. The bank card stores user identification information, such as the user's unique identification number, name, ID number, etc. in the bank corresponding to the bank card. The embodiment of the present application does not limit this. The user identification information is also referred to as card information in the embodiment of the present application. The user can swipe the bank card at the designated location of the POS machine, and the POS machine can read the card information stored in the bank card. The POS machine can send the read card information to the main processor chip.

[0044] Optionally, after receiving the card information, the main processor chip can obtain the user's bank card balance based on the card information and determine whether the balance meets the charging conditions. If the charging conditions are met, the card information is used as a charging instruction for the current vehicle, and all its functions are turned on, that is, all its built-in program codes are controlled to run normally. At this time, the main processor chip enters the normal working mode. The main processor chip can also control all relays to be turned on. At this time, the circuits between all slave processor chips and the power supply are turned on, and the power supply can normally supply power to each slave processor chip, that is, each slave processor chip is powered on. After each slave processor chip is powered on, all its built-in program codes are controlled to run normally. After the user inserts the charging gun into the charging port of the current vehicle, the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0045] If the charging condition is not met, the main processor chip can send an insufficient balance prompt to the display device, and the display device can display the insufficient balance prompt to remind the user that the balance of the bank card used is insufficient.

[0046] Similar to the aforementioned embodiment, the charging condition here may be that the balance is greater than a preset threshold, the balance is greater than the cost of one charge, etc. The charging condition may be flexibly set according to actual conditions, and the embodiment of the present application does not limit this.

[0047] Similar to the above embodiment, the above verification of the bank card balance is only an example, and other information can also be verified. If the verification passes, the card information is used as a charging instruction for the current vehicle; if the verification fails, the main processor chip can send a verification failure prompt to the display device, and the display device can display the verification failure prompt to remind the user that the bank card used by the user has failed the verification. Alternatively, the main processor chip can also omit the verification step, and after receiving the card information, directly use the card information as a charging instruction for the current vehicle.

[0048] In the above embodiment, the user can swipe the bank card at the designated location of the POS machine, and the POS machine can read the card information stored in the bank card, and the POS machine can send the read card information to the main processor chip. After receiving the card information, the main processor chip uses the card information as a charging instruction for the current vehicle, enters the normal working mode, and controls the power-on of multiple slave processor chips through multiple relays; so that after the user inserts the charging gun into the charging port of the current vehicle, the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0049] In some embodiments, see Figure 4As shown, the charging device also includes a charging gun, which is connected to the main processor chip via a controller area network CAN. The charging gun is used to be inserted into the charging port of the current vehicle to charge the current vehicle. When the charging gun is inserted into the charging port, a plug-and-charge instruction is sent to the main processor chip, and the main processor chip uses the plug-and-charge instruction as a charging instruction for the current vehicle.

[0050] Among them, the charging device also includes a charging gun. The charging device provided in the embodiment of the present application supports plug-and-charge. The user can directly insert the charging gun into the charging port of the current vehicle. When the charging gun is inserted into the charging port, a plug-and-charge instruction is sent to the main processor chip. After receiving the plug-and-charge instruction, the main processor chip uses the plug-and-charge instruction as a charging instruction for the current vehicle and turns on all its own functions, that is, controls all its built-in program codes to run normally. At this time, the main processor chip enters the normal working mode. The main processor chip can also control all relays to be turned on. At this time, the circuits between all slave processor chips and the power supply are turned on, and the power supply can normally supply power to each slave processor chip, that is, each slave processor chip is powered on. After each slave processor chip is powered on, all its built-in program codes are controlled to run normally, so that the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0051] In the above embodiment, the charging device also includes a charging gun, which is connected to the main processor chip via a controller area network CAN. The charging gun is used to be inserted into the charging port of the current vehicle to charge the current vehicle. When the charging gun is inserted into the charging port, a plug-and-charge instruction is sent to the main processor chip. The main processor chip uses the plug-and-charge instruction as a charging instruction for the current vehicle, enters a normal working mode, and controls multiple slave processor chips to power on through multiple relays, so that the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0052] In some embodiments, see Figure 5 As shown, the charging device also includes a communication module, which is connected to the main processor chip via a secure digital input and output interface SDIO. The communication module is used to receive a start charging instruction sent by the cloud platform and send the start charging instruction to the main processor chip. The main processor chip uses the start charging instruction as a charging instruction for the current vehicle.

[0053] Among them, the user can perform trigger operations related to car charging on the terminal, and the terminal interacts with the cloud platform based on these trigger operations, and the cloud platform generates a start charging instruction based on the interaction with the terminal. The cloud platform can send the start charging instruction to the communication module in the charging device, and the communication module further sends the start charging instruction to the main processor chip. The main processor chip uses the start charging instruction as a charging instruction for the current vehicle and turns on all its own functions, that is, controls all its built-in program codes to run normally. At this time, the main processor chip enters the normal working mode. The main processor chip can also control all relays to be turned on. At this time, the circuit between all slave processor chips and the power supply is turned on, and the power supply can normally supply power to each slave processor chip, that is, each slave processor chip is powered on. After each slave processor chip is powered on, all its built-in program codes are controlled to run normally. After the user inserts the charging gun into the charging port of the current vehicle, the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0054] In the above embodiment, the user can perform trigger operations related to car charging on the terminal. The terminal interacts with the cloud platform based on these trigger operations. The cloud platform generates a start charging instruction based on the interaction with the terminal and sends the start charging instruction to the communication module in the charging device. The communication module further sends the start charging instruction to the main processor chip. The main processor chip uses the plug-and-charge instruction as the charging instruction for the current vehicle, enters the normal working mode and controls the power-on of multiple slave processor chips through multiple relays, so that after the user inserts the charging gun into the charging port of the current vehicle, the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0055] In some embodiments, the charging start instruction is sent by the cloud platform based on the interaction with an application on the terminal, and the interaction between the cloud platform and the application is triggered by the user on the application.

[0056] Among them, when a user wants to use a charging device to charge his new energy vehicle, he can find the target identifier for selecting the charging device on the application installed on the terminal, and then click the charging button. The application will generate a charging request and send it to the cloud platform. The charging request carries the above-mentioned target identifier and the user identifier of the user currently logged in to the application. The cloud platform parses the charging request to obtain the above-mentioned target identifier and user identifier, and determines whether the balance of the user identifier in the application meets the charging conditions. If the charging conditions are met, the network communication address of the communication module in the above-mentioned charging device is searched based on the target identifier, and a start charging instruction is sent to the communication module in the above-mentioned charging device based on the network communication address. The communication module further sends the start charging instruction to the main processor chip. The main processor chip uses the start charging instruction as a charging instruction for the current vehicle and turns on all its own functions, that is, controls all its built-in program codes to run normally. At this time, the main processor chip enters normal working mode. The main processor chip can also control all relays to turn on. At this time, the circuits between all slave processor chips and the power supply are turned on, and the power supply can normally supply power to each slave processor chip, that is, each slave processor chip is powered on. After each slave processor chip is powered on, all its built-in program codes are controlled to run normally. After the user inserts the charging gun into the charging port of the current vehicle, the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0058] In the above embodiment, the main processor chip can be awakened by the application to enter the normal operating mode, and multiple slave processor chips can be powered on by multiple relays, so that after the user inserts the charging gun into the charging port of the current vehicle, the main processor chip can cooperate with each slave processor chip to complete the charging of the current vehicle.

[0059] In some embodiments, the charging start instruction is sent by the cloud platform when the terminal successfully pays by scanning the QR code corresponding to the charging device.

[0060] Among them, when a user wants to use a charging device to charge his new energy vehicle, he can use the terminal to scan the QR code corresponding to the charging device. The terminal parses the scanned QR code information to obtain the unique identification of the charging device, generates a charging request based on the unique identification and sends it to the cloud platform. The cloud platform parses the charging request to obtain the above-mentioned unique identification, determines the amount to be paid for charging based on the unique identification, and returns the amount to be paid for charging to the terminal. The terminal displays the amount to be paid for charging. After the user successfully pays the amount on the terminal, the terminal sends a payment success message to the cloud platform. After receiving the payment success message, the cloud platform searches for the network communication address of the communication module in the above-mentioned charging device based on the above-mentioned unique identification, and sends a start charging instruction to the communication module in the above-mentioned charging device based on the network communication address. The communication module further sends the start charging instruction to the main processor chip. The main processor chip uses the start charging instruction as a charging instruction for the current vehicle and turns on all its own functions, that is, controls all its built-in program codes to operate normally.
