Fig. 1 is a flowchart of a control method of a charging pile according to an embodiment of the present invention, as shown in fig. 1, the control method of the charging pile includes the steps of:
step S102, after detecting the power-on signal of the charging pile, the first charging controller sends the power-on signal to the second charging controller, wherein the second charging controller sends the maximum charging voltage of the vehicle to be charged to the first charging controller after receiving the power-on signal.
Optionally, fig. 2 is a timing chart of a control method of a charging pile according to an embodiment of the present invention, as shown in fig. 2, after the charging pile is powered on at a low voltage, a first charging controller (i.e. CCU 1) sends a low-voltage power-on completion flag bit to a second charging controller (i.e. CCU 2), and the second charging controller sends a message CHM after receiving the low-voltage power-on flag bit.
After receiving a BHM message sent from a vehicle end (i.e., a vehicle to be charged), the CCU2 sends a vehicle end highest allowable charging voltage contained in the BHM message to the CCU1, the CCU1 sends the vehicle end highest allowable charging voltage to a charging manager EMS, and the EMS makes an internal judgment after receiving the voltage signal, for example, confirms that the lowest output voltage of the charging pile is smaller than the vehicle end allowable voltage, and if the lowest output voltage is not smaller than the vehicle end allowable voltage, the charging is considered to be possible, otherwise, the charging is not possible.
FIG. 3 is a schematic diagram of communications between CCU1 and CCU2, according to an embodiment of the present invention, where CCU1 and CCU2 perform CAN communications to together perform charge control, as shown in FIG. 3. Wherein, CCU1 comprises: the device comprises a CAN signal receiving and transmitting module, a temperature control module, an insulation module, a voltage and current control module, a fault diagnosis module, a relay control module and other functional modules related to charging control; CCU2 then includes a charge flow control module. As shown in fig. 3, in the embodiment of the present invention, CCU2 may support a national charging procedure or an european charging procedure.
In step S104, the first charging controller sends the maximum charging voltage to the charging manager after receiving the maximum charging voltage, wherein the charging manager determines whether to allow charging based on the maximum charging voltage, and generates a feedback signal.
After receiving a BHM message sent from a vehicle end (i.e., a vehicle to be charged), the CCU2 sends a vehicle end highest allowable charging voltage contained in the BHM message to the CCU1, the CCU1 sends the vehicle end highest allowable charging voltage to a charging manager EMS, and the EMS makes an internal judgment after receiving the voltage signal, for example, confirms that the lowest output voltage of the charging pile is smaller than the vehicle end allowable voltage, and if the lowest output voltage is not smaller than the vehicle end allowable voltage, the charging is considered to be possible, otherwise, the charging is not possible.
In step S106, the first charging controller controls the second charging controller to start the charging process of the vehicle to be charged to charge the vehicle to be charged when it is determined that charging is allowed based on the feedback signal.
As can be seen from the above, in the embodiment of the present invention, the charge control flow management of the charging pile can be completed by using CCU2 alone, and other charging related functions are completed by CCU1, after detecting the power-on signal of the charging pile, the first charging controller sends the power-on signal to the second charging controller, wherein the second charging controller sends the maximum charging voltage of the vehicle to be charged to the first charging controller after receiving the power-on signal; the first charging controller sends the maximum charging voltage to the charging manager after receiving the maximum charging voltage, wherein the charging manager determines whether charging is allowed or not based on the maximum charging voltage, and generates a feedback signal; when the first charging controller determines that charging is allowed based on the feedback signal, the second charging controller is controlled to start a charging flow of the vehicle to be charged so as to charge the vehicle to be charged, and on the basis of the original charging function of the charging pile, function division is performed, so that the purpose of complexity of control logic of the charging controller of the low charging pile is achieved, and meanwhile portability of a charging control unit of the charging pile is improved.
It is easy to notice that, because the charging process is controlled to be completed in an independent controller CCU2, other functions related to charging are integrated and completed in CCU1, and CCU1 and CCU2 carry out CAN communication to complete charging control jointly, because CCU2 does not need to be changed, only signals and variables of CCU1 need to be changed according to the requirements of customers, the aim of shortening the development period of new projects is effectively achieved, and the portability of a charging control unit of a charging pile is also improved.
Therefore, the control method of the charging pile solves the technical problems that the control logic of the charging control unit of the charging pile is complex and the portability is low in the related technology.
According to the above embodiment of the present invention, when the feedback signal indicates that the lowest output voltage of the charging pile is smaller than the maximum charging voltage, it is determined that charging of the vehicle to be charged is permitted. The safety in the charging process can be effectively improved.
According to the above embodiment of the present invention, the control method of the charging pile may further include: when the first charging controller receives an insulation detection signal, insulation detection is carried out on the charging pile to obtain an insulation detection result of the charging pile, wherein the insulation detection signal is a signal generated by the charging manager when the charging manager determines that charging of the vehicle to be charged is allowed; and when the insulation detection result shows that the circuit insulation of the charging pile is normal, the first charging controller sends an insulation completion signal to the second charging controller, wherein the second charging controller sends the insulation completion signal to the vehicle to be charged after receiving the insulation completion signal so as to inform the vehicle to be charged that the vehicle to be charged is successfully identified by the charging pile.
As shown in fig. 2, after the internal determination of the EMS, if the charging is allowed to be performed normally, the allowed insulation detection flag bit is sent to the CC1, after receiving the flag bit, the CCU1 performs internal insulation detection calculation, if the circuit insulation is normal, the CCU1 sends an insulation completion flag bit to the CCU2, and after receiving the flag bit, the CCU2 sends a CRM 0xAA message to the vehicle end, which indicates that the charging pile can identify the vehicle end normally. Wherein, CCU2 sends CRM 0x00 to the vehicle terminal after receiving the BHM message, and the vehicle terminal sends BRM message after receiving the CRM message. The safety of the charging pile circuit can be improved through insulation detection.
When the CCU1 performs insulation detection calculation, an insulation resistance value is generated, the CCU1 classifies fault levels according to the insulation resistance value, for example, the insulation resistance value is 100 kiloohms/V is three-level fault, 500 kiloohms/V is two-level fault, 700 kiloohms/V is one-level fault, if the three-level fault is generated, the CCU1 stops the charging process, the CCU2 sends a CCU1 stop instruction, and the CCU2 receives the stop instruction and sends the stop instruction to a vehicle end CST.
According to the above embodiment of the present invention, the control method of the charging pile may further include: and when the insulation detection result shows that the insulation resistance value of the charging pile is larger than the preset resistance value, determining that the circuit of the charging pile is insulated normally. In this embodiment, when it is detected that the insulation resistance value is larger than the predetermined resistance value, the insulation function can be effectively performed, and the safety can be improved.
According to the above embodiment of the present invention, the first charging controller, when determining that charging is allowed based on the feedback signal, may control the second charging controller to start a charging flow of the vehicle to be charged, and may include: when the first charging controller receives the charging parameters sent by the charging manager, the charging parameters are sent to the second charging controller, wherein the second charging controller sends the charging parameters to the vehicle to be charged after receiving the charging parameters, and the vehicle to be charged generates charging request information after receiving the charging parameters; the first charging controller sends the charging request information to the charging manager after receiving the charging request information, wherein the charging manager generates charging management information after receiving the charging request information; after receiving the charging management information, the first charging controller sends the charging management information to the second charging controller so as to control the charging flow of the vehicle to be charged by using the second charging controller.
As shown in fig. 2, the EMS sends information (i.e., charging parameters) of voltage and current to the CCU1, after receiving the CTS message sending flag bit sent by the CCU2, the CCU1 sends the information of voltage and current to the CCU2, and the CCU2 sends the CML message to the vehicle end after receiving the information of voltage and current. The vehicle end receives the CRM 0xAA and then sends a message BCP message, and the CCU2 sends a CTS to the vehicle end after receiving the BCP message.
In the above embodiment, after the second charge controller receives the charge management information, the charge management information is sent to the vehicle to be charged.
As shown in fig. 2, after receiving CML, the vehicle end sends a message BRO 0x00 and then sends a BRO 0xAA message, and CCU2 sends CRO 0x00 to the vehicle end after receiving BRO 0xAA and then sends CRO 0xAA, and after receiving CRO 0xAA sent by CCU2, the vehicle end sends BCL to CCU2, and CCU2 sends information such as voltage and current contained in the BCL message to EMS, and the EMS makes internal judgment (for example, the EMS adjusts voltage and current components of a charging pile to enable the charging pile to meet voltage and current requirements sent by CCU 1).
In addition, as shown in fig. 2, after receiving the voltage and current request information sent by the CCU1, the EMS sends the information such as the voltage, the current and the charging time to the CCU1, the CCU1 forwards the information sent by the EMS to the CCU2, and the CCU2 sends the information such as the output voltage, the current and the charging time of the charging pile to the vehicle end through CCS messages.
According to the embodiment of the invention, the control method of the charging pile further comprises the following steps: and after receiving the charging end signal, the first charging controller terminates the charging flow of the charging pile and sends the charging end signal to the second charging controller, wherein the second charging controller sends the charging end signal to the vehicle to be charged.
As shown in fig. 2, the vehicle end may actively terminate charging, and the charging pile may also actively terminate charging. For example, after meeting the charge amount set in advance by the customer, the EMS may send a charge termination to the CCU1, and the CCU1 internally terminates the charging process (for example, controls the charging gun relay to open), and the CCU2 may send a BST message to the vehicle end after receiving the termination flag bit sent by the CCU 1. And after receiving the BSD sent by the vehicle end, the CCU2 sends the CSD to the vehicle end.
It should be noted that, during message interaction, there is a message timeout detection, for example, CCU2 sends CRO 0xAA to the vehicle end, and if 65s fails to receive the BCL message sent by the vehicle end, CCU2 will report a BCL reception timeout fault.
In addition, in the embodiment of the invention, the logic of the CCU1 controller can be changed according to different clients to meet the requirement, and the CCU2 is the message interaction logic which is made according to the standard and does not need to be changed. For example, a customer may require a calculation method to change the insulation resistance value, so only insulation calculation logic changes for CCU1 are required, and CCU2 does not need to be changed. For another example, the customer may require that the charging stake not be able to output 300A current for five minutes, and if greater than five minutes, then current is reduced to 250A output. Only the current request logic sent by the CCU1 to the EMS needs to be changed, and CCU2 does not need to be changed. For another example, the CCU1 controls the relay to be turned off, different manufacturers of the relay have different relay state feedback time, and different sampling time is set according to different relays when the insulation voltage is sampled.
Fig. 4 is a timing chart of an alternative control method of a charging pile according to an embodiment of the present invention, as shown in fig. 4, where the charging process is implemented by adding an EVSE between CCU2 and EV on the basis of the national charging process shown in fig. 2, that is, if the charging is the european charging, interaction between CCU2 and EV terminals is required through a SECC (power supply equipment communication controller). No matter the European and national CCU2 is not changed, the high portability of the CCU2 is ensured, the development period can be shortened, and the development cost is saved.
FIG. 5 is a schematic diagram of the interaction inside a charging pile according to an embodiment of the present invention, as shown in FIG. 5, EMS communicates with CCU1 through CAN signals, CCU1 communicates with CCU2 through CAN signals, and CCU2 communicates with EV through CAN signals (national version); if the European charging procedure is adopted, CCU2 communicates with EV through SECC signals.
The control method of the charging pile provided by the embodiment of the invention CAN control the charging flow in an independent controller CCU2 based on the characteristic that the charging flow control is a standardized flow, and put other functions related to charging in the CCU1 to be integrated, and the CCU1 and the CCU2 carry out CAN communication to jointly complete the charging control, thereby having the advantages of reduced operation intensity of the controller, clear structure and better portability of the controller. The CCU1 receives CAN signals transmitted by controllers such as EMS, SECC and the like, the signals may include current, voltage, temperature, electric quantity, resistance and the like, the CAN signals are sent to the CCU2 according to a certain control logic, the CCU2 receives the CAN signals of the CCU1 to operate a corresponding charging flow, and corresponding CAN signals are generated and sent to the CCU1. For example, if the flow is an european style flow, the CCU2 receives a Cab leclckreq message and sends a Cab leclckres message. The CCU1 may change the corresponding control according to different product requirements, such as the timing of the relay opening, the division of fault classes, the setting of the voltage-current threshold, etc. CCU2 once the control logic is established, the control of CCU2 is changed unless the standard is changed. The portability of CCU2 is high. The European version is just a name, and may be a charging process of the day system or the American system. The national version here is the charging flow required by the national standard.
