Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] In the description of the embodiments of the present invention, unless otherwise specified, "plurality" means two or more. "And / or" describes the association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone.

[0021] The terms "first," "second," and so on, used in the embodiments of the present invention are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, technical features designated as "first" or "second" may explicitly or implicitly include at least one such feature.

[0022] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The present invention provides a charging pile power regulation method, device and storage medium based on OCPP, which are described below respectively.

[0024] Figure 1 A flow chart of an embodiment of the OCPP-based charging pile power regulation method provided by the present invention is shown as follows: Figure 1 As shown, the charging pile power regulation method based on OCPP includes: S101. Receive an OCPP request message sent by a CSMS; the OCPP request message includes smart charging power information.

[0025] The OCPP-based charging pile power regulation method provided by the present invention can be executed by a charging pile. The charging pile and the CSMS communicate through an open charging protocol. The open charging protocol includes a specification definition of smart charging, which is used to adjust the charging power of the current charging pile.

[0026] The charging pile receives the OCPP request message sent by the CSMS, parses the OCPP request message, and obtains the smart charging power information contained therein.

[0027] S102. Determine a target output power of the charging pile based on the intelligent charging power information, temperature parameters, and battery parameters; the temperature parameters and the battery parameters are obtained by a billing unit provided inside the charging pile.

[0028] The charging pile can obtain temperature parameters and battery parameters through the internal billing unit. The temperature parameters may include the air inlet temperature, air outlet temperature and charging gun tip temperature. The battery parameters may include the battery production time, the number of battery charges and the current maximum temperature of the battery.

[0029] The target output power of the current charging pile is comprehensively calculated by normalizing the exponential function and actual parameter requirements, combined with the smart charging defined by OCPP2.0.

[0030] S103. When the time period power limitation strategy is enabled, the optimal output power of the charging pile is determined based on the current power limit and the target output power; the time period power limitation strategy is a preset power limit corresponding to different time periods.

[0031] The time period power limit strategy is to limit the power corresponding to different time periods preset locally at the charging pile. The time period power limit strategy can be set locally by the operator to set the power of the charging pile. The purpose is to flexibly adjust the output power of each charging pile for manufacturer debugging or charging stations.

[0032] For example, a time-based power limit strategy can set different maximum power limits for different time periods. For example, charging power can be reduced during peak hours and increased during off-peak hours to balance grid load and avoid increasing pressure on the grid during peak hours. For example, a charging station can have 48 pre-set power limits for half-hour intervals, as shown in Table 1.

[0033] Table 1: Power limits during time periods

[0034] When the time-based power limit strategy is enabled, the current limit power is compared with the target output power, and the smaller value is determined as the optimal output power of the charging pile. Based on the actual output of the charging pile, mechanical power limiting is avoided to prevent overheating or high power output to older electric vehicles, which may cause damage to the vehicle.

[0035] In summary, the OCPP-based charging pile power regulation method provided in the embodiments of the present invention receives and parses the OCPP request message sent by the CSMS to obtain intelligent charging power information. Combined with the temperature and battery parameters obtained by the billing unit, it calculates the target output power of the charging pile. When the power limit strategy for the current period is enabled, the current limit power and the target output power are compared, and the smaller value is determined as the optimal output power of the charging pile. This can prevent fires or damage to electrical components in the charging pile and vehicle in high-temperature environments and with old batteries, thereby ensuring charging safety.

[0036] In some embodiments of the present invention, before determining the target output power of the charging pile based on the intelligent charging power information, temperature parameters, and battery parameters, the method further includes: collecting the temperature parameters through a billing unit; The charging unit receives the CAN transmission telemetry message sent regularly by the control board; the CAN transmission telemetry message includes the battery parameters.

[0037] In some embodiments of the present invention, the temperature parameters include air inlet temperature, air outlet temperature, and charging gun tip temperature; The battery parameters include battery production time, battery charging times and the current maximum temperature of the battery.

[0038] The billing unit (ZM029) is a module installed inside the charging pile. It collects the temperatures of the air inlet, air outlet, and gun tip through multiple sampling points. The air inlet temperature is collected through chassis temperature sampling point 1, and the air outlet temperature is collected through chassis temperature sampling point 2. A DC+ indicates the DC+ temperature of the A gun tip, and A DC- indicates the DC- temperature of the A gun tip.

[0039] The vehicle BMS information is transmitted by the bottom control board through CAN telemetry message, and uploaded to the billing unit at regular intervals. Figure 2 The schematic diagram of the ZM029 CAN message receiving electrical port provided by the present invention is as follows: Figure 2 Its sampling parameters are shown in Table 2.

[0040] Table 2: Sampling parameters

[0041] The OCPP-based charging pile power regulation method provided in an embodiment of the present invention collects charging pile and vehicle data, such as inlet and outlet temperatures, vehicle battery information, and vehicle demand information, and combines it with the smart charging defined by OCPP2.0 to comprehensively calculate the optimal output power of the current charging pile.

[0042] In some embodiments of the present invention, the target output power is expressed as follows:

[0043] in, Power is the target output power, The coefficient for smart charging, SmartPower For intelligent charging power, Represents the coefficient of each sample data, is the air inlet temperature, is the air outlet temperature, For battery production time, Charge the battery times, It is the DC+temperature of the gun tip. is the DC-temperature of the gun tip, is the current maximum battery temperature, NeedPower is the required power, k To control the degree of weight concentration, the value is 2.

[0044] Based on the normalized exponential function and actual parameter requirements, the calculation formula for the combined power is defined as follows:

[0045] in, Power is the target output power, The coefficient for smart charging, SmartPower For intelligent charging power, Represents the coefficient of each sample data, is the air inlet temperature, is the air outlet temperature, is the battery production time (converted to timestamp), Charge the battery times, It is the DC+temperature of the gun tip. is the DC-temperature of the gun tip, is the current maximum temperature of the battery, NeedPower is the required power (required voltage * required current), and k is the control weight concentration degree, which is 2.

[0046] In some embodiments of the present invention, after determining the target output power of the charging pile based on the intelligent charging power information, temperature parameters, and battery parameters, the method further includes: Based on the status information of the charging pile, determine whether the time period power limit strategy is enabled; When the status information of the charging pile is offline, the time period power limit strategy is enabled; When the status information of the charging pile is online, the time period power limit strategy is closed.

[0047] In some embodiments of the present invention, further comprising: When the time period power limitation strategy is turned off, the target output power is determined as the optimal output power.

[0048] The power limit strategy for each time period can be determined based on the status information of the charging pile. When the status information of the charging pile is offline, the power limit strategy for each time period is automatically enabled to automatically monitor the charging pile. When the status information of the charging pile is online, the power limit strategy for each time period is disabled to monitor the charging pile in real time.

[0049] When the time period power limit strategy is turned off, the target output power will be directly determined as the optimal output power.

[0050] In some embodiments of the present invention, after receiving the OCPP request message sent by the CSMS, the method further includes: Send a response message to the CSMS; the response message is used to indicate whether the charging pile accepts the configuration of the charging power information.

[0051] CSMS will control the charging power of each charging pile according to the pre-configuration, and the charging station will be configured with a maximum power. Figure 3 This is a schematic diagram of the intelligent charging message interaction process provided by the present invention. The message interaction is as follows Figure 3 The message format example is as follows: (1) Example of CSMS sending a message (SetChargingProfileRequest) to a charging pile: { "evseId":1,"chargingProfile":{"id":2,"stackLevel":1,"chargingProfilePurpose":"TxDefaultProfile", "chargingProfileKind":"Absolute","recurrencyKind":"Daily","validFrom":"2024-09-19T03:00:00.00Z", "validTo":"2024-09-19T23:00:00.00Z","transactionId":"123456", "chargingSchedule":[{"id":111,"startSchedule":"2024-09-19T06:10:00.00Z","duration":7200, "chargingRateUnit":"W","chargingSchedulePeriod":[{"startPeriod":0,"limit":3000,"numberPhases":3}]}]} } Where, evseId is the charging gun ID, chargingProfile is the charging profile, id is the identifier of the charging profile, stackLevel is the level of the current charging profile, chargingProfilePurpose is the profile property (TxDefaultProfile is valid by default), chargingProfileKind indicates the schedule type (Absolute indicates a fixed start time, i.e., starting from the startSchedule time point), recurrencyKind indicates the recurrence type (Daily indicates daily), validFrom indicates the start time of the profile, validTo indicates the end time of the profile, transactionId indicates the transaction ID, chargingSchedule is the power limit schedule, startSchedule indicates the power limit start time, duration indicates the limit duration in seconds, chargingRateUnit indicates the unit (W is watts), chargingSchedulePeriod indicates the specific execution attribute value of the schedule, startPeriod indicates the number of seconds after startSchedule starts, limit is the actual power limit value in W, and numberPhases is the number of phases.

[0052] (2) Example of a charging pile sending a message (SetChargingProfileResponse) to CSMS: { "status":"Accepted" } Status indicates the response to the configuration request sent by the CSMS. Accepted indicates acceptance, and Rejected indicates rejection. For example, the status field in the response message can be used to inform the CSMS whether the charging station accepts the configuration request. Accepted indicates that the charging station has successfully received and approved the configuration and will execute the charging plan according to the request. Rejected indicates that the charging station refuses to execute the configuration and requires the CSMS to adjust and resend the request.

[0053] Through the response message, CSMS can confirm whether the charging pile has accurately parsed and processed the configuration instructions, avoiding configuration failure due to communication failure or data error.

[0054] Optionally, if the charging pile returns Rejected, the CSMS can trigger a retry mechanism or alarm process to improve system robustness.

[0055] When accepting a configuration, the charging pile will adjust the charging strategy according to the configuration content (such as power limit and time plan). When rejecting a configuration, the CSMS can resend the revised request.

[0056] The OCPP-based charging pile power regulation method provided in the embodiment of the present invention can ensure the reliability and consistency of charging configuration.

[0057] Figure 4 This is a flow chart of the power regulation method combining OCPP2.0 intelligent charging and sampling information provided by the present invention, as shown in FIG. Figure 4 As shown, the method includes: The user starts to choose charging and collects the air inlet temperature, air outlet temperature, battery production time, battery charge times, battery current temperature and charging gun tip temperature.

[0058] If the smart charging configuration is received from the remote backend, the corresponding power limit will be analyzed.

[0059] The current output power is obtained through normalization function processing.

[0060] Determine whether the local time period power is enabled. If not, use the normalized power. If enabled, determine the minimum power value of the two.

[0061] Output the minimum power value and send it to the control board to limit the current charging power.

[0062] The power regulation method proposed in this paper combines OCPP2.0 intelligent charging and sampling information. By collecting vehicle and charging pile temperature and battery information, combined with the intelligent charging power limit issued by the CSMS, a normalized exponential function is used to calculate the local optimal power of the charging pile. This method prevents fires or damage to electrical components in charging piles and vehicles in high-temperature environments and with old batteries. This method, especially with the arrival of high temperatures in various regions, addresses the pain point of charging hazards and ensures the safety of all parties involved, including personnel and property.
