[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] In the description of the embodiments of the present invention, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0043] The terms "first," "second," etc., used in the embodiments of this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a technical feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0044] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] This invention provides a charging pile power adjustment method, device, and storage medium based on OCPP, which are described below.

[0046] Figure 1 This is a schematic flowchart of an embodiment of the OCPP-based charging pile power adjustment method provided by the present invention, as shown below. Figure 1 As shown, the power regulation method for charging piles based on OCPP includes:

[0047] S101. Receive an OCPP request message sent by CSMS; the OCPP request message contains smart charging power information.

[0048] The charging pile power adjustment method based on OCPP provided by this invention can be executed by the charging pile itself. The charging pile and CSMS communicate through the charging open protocol, which contains the standard definition of smart charging and is used to adjust the charging power of the current charging pile.

[0049] The charging pile receives the OCPP request message sent by CSMS, parses the OCPP request message, and obtains the smart charging power information contained therein.

[0050] S102. Based on the intelligent charging power information, temperature parameters, and battery parameters, determine the target output power of the charging pile; the temperature parameters and battery parameters are obtained through a billing unit installed inside the charging pile.

[0051] The charging station can obtain temperature and battery parameters through its internal billing unit. Temperature parameters can include air inlet temperature, air outlet temperature, and charging gun head temperature. Battery parameters can include battery production time, battery charging cycles, and the battery's current highest temperature.

[0052] By combining the normalized exponential function and actual parameter requirements with the smart charging defined by OCPP2.0, the target output power of the current charging pile is calculated comprehensively.

[0053] S103. When the time period power limiting strategy is activated, the optimal output power of the charging pile is determined based on the current time limit power and the target output power; the time period power limiting strategy is to preset the corresponding limit power for different time periods.

[0054] The time-based power limiting strategy is a power limitation policy that is preset locally on the charging pile for different time periods. The operator can set the power of the charging pile locally, so as to allow the manufacturer to debug or the charging station to flexibly adjust the output power of each charging pile.

[0055] For example, a time-based power limiting strategy could involve setting different maximum power limits for different time periods, such as reducing charging power during peak hours and increasing charging power during off-peak hours to balance the grid load and avoid exacerbating grid pressure during peak hours. For instance, a charging station could have 48 preset time-based power limits, with intervals of half an hour, as shown in Table 1.

[0056] Table 1: Power Limitations During Different Time Periods

[0057]

[0058] When the time-limited power policy is activated, the current time-limited power and the target output power are compared, and the smaller value is determined as the optimal output power of the charging station. Based on the actual output of the charging station, mechanical power limiting is prevented to avoid overheating or outputting too much power to older electric vehicles, which could potentially damage the vehicles.

[0059] In summary, the charging pile power adjustment method based on OCPP provided in this embodiment of the invention receives and parses the OCPP request message sent by CSMS to obtain intelligent charging power information. Combined with the temperature parameters and battery parameters obtained by the billing unit, the target output power of the charging pile is calculated. When the power limiting policy is enabled at that time, the current limiting power and the target output power are compared, and the smaller value is determined as the optimal output power of the charging pile. This method can prevent fires or damage to electrical components in charging piles and vehicles under high temperature environments and old battery conditions, thus ensuring charging safety.

[0060] 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:

[0061] The temperature parameters are collected through the billing unit;

[0062] The billing unit receives CAN telemetry messages periodically sent by the control board; the CAN telemetry messages contain the battery parameters.

[0063] In some embodiments of the present invention, the temperature parameters include the inlet temperature, the outlet temperature, and the charging gun head temperature.

[0064] The battery parameters include battery production time, number of battery charge cycles, and the current highest battery temperature.

[0065] The billing unit (ZM029) is a module installed inside the charging pile. It collects the temperature of the air inlet, air outlet, and gun head through multiple sampling points. The air inlet temperature is collected through the chassis temperature sampling point 1, and the air outlet temperature is collected through the chassis temperature sampling point 2. A DC+ represents the DC+ temperature of gun head A, and A DC- represents the DC- temperature of gun head A.

[0066] Vehicle BMS information is transmitted via CAN telemetry messages from the underlying control board and periodically uploaded to the billing unit. Figure 2 This is a schematic diagram of the electrical port for receiving ZM029 CAN messages provided by the present invention. The electrical structure is as follows: Figure 2 As shown in Table 2, its sampling parameters are as follows.

[0067] Table 2: Sampling Parameters

[0068]

[0069] The charging pile power adjustment method based on OCPP provided in this embodiment of the invention can comprehensively calculate the optimal output power of the current charging pile by collecting data from the charging pile and the vehicle, such as the temperature of the air inlet and outlet, vehicle battery information, and vehicle demand information, combined with the smart charging defined by OCPP2.0.

[0070] In some embodiments of the present invention, the expression for the target output power is as follows:

[0071]

[0072] in, Power For the target output power, The coefficient for smart charging, SmartPower For intelligent charging power, Represents the coefficients of each sampled data. The inlet temperature, The temperature at the air outlet. For battery production time, Number of battery charge cycles DC+ temperature of the nozzle tip DC temperature of the nozzle. This is the highest temperature currently recorded in the battery. NeedPower For the required power, k To control the degree of weight concentration, the value is 2.

[0073] Based on the normalized exponential function and actual parameter requirements, the formula for calculating combined power is defined as follows:

[0074]

[0075] in, Power For the target output power, The coefficient for smart charging, SmartPower For intelligent charging power, Represents the coefficients of each sampled data. The inlet temperature, The temperature at the air outlet. Battery production time (converted to a timestamp), Number of battery charge cycles DC+ temperature of the nozzle tip DC temperature of the nozzle. The current highest battery temperature is represented by NeedPower, which is the required power (required voltage * required current), and k is the degree of control weight concentration, with a value of 2.

[0076] 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:

[0077] Based on the status information of the charging pile, determine whether the power limiting strategy for a certain period is enabled;

[0078] When the charging station's status information indicates that it is offline, the time-limited power policy is activated.

[0079] When the charging station's status information indicates it is online, the time-based power limiting policy is turned off.

[0080] In some embodiments of the present invention, it further includes:

[0081] When the time-limited power policy is off, the target output power is determined as the optimal output power.

[0082] The system can determine whether to enable the time-based power limiting policy based on the charging pile's status information. When the charging pile is in an offline state, the time-based power limiting policy is automatically enabled for automatic monitoring. When the charging pile is in an online state, the time-based power limiting policy is disabled for real-time monitoring.

[0083] When the time-limited power policy is turned off, the target output power will be directly determined as the optimal output power.

[0084] In some embodiments of the present invention, after receiving the OCPP request message sent by CSMS, the method further includes:

[0085] Send a response message to CSMS; the response message is used to indicate whether the charging pile accepts the configuration of the charging power information.

[0086] CSMS controls the charging power of each charging station according to pre-configured settings, and each charging station is configured with a maximum power output. 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 As shown, the message format example is as follows:

[0087] (1) Example of CSMS sending a message (SetChargingProfileRequest) to a charging pile:

[0088] {

[0089] "evseId":1,"chargingProfile":{"id":2,"stackLevel":1,"chargingProfilePurpose":"TxDefaultProfile",

[0090] "chargingProfileKind":"Absolute","recurrencyKind":"Daily","validFrom":"2024-09-19T03:00:00.00Z",

[0091] "validTo":"2024-09-19T23:00:00.00Z","transactionId":"123456",

[0092] "chargingSchedule":[{"id":111,"startSchedule":"2024-09-19T06:10:00.00Z","duration":7200,

[0093] "chargingRateUnit":"W","chargingSchedulePeriod":[{"startPeriod":0,"limit":3000,"numberPhases":3}]}]}

[0094] }

[0095] Wherein, evseId is the charging gun number, chargingProfile is the charging configuration, id is the identifier of the charging configuration, stackLevel is the level of the current charging profile, chargingProfilePurpose is the profile property (TxDefaultProfile is the default valid), chargingProfileKind indicates the type of time schedule (Absolute means it starts at a fixed time, i.e., from the startSchedule time point), recurrencyKind indicates the recurrence type (Daily means every day), validFrom indicates the start time of the profile's effective period, validTo indicates the end time of the profile's effective period, transactionId indicates the transaction ID, chargingSchedule is the power limit effective schedule, startSchedule indicates the power limit start time, duration indicates the duration of the limit in seconds, chargingRateUnit indicates the unit, W is watts, chargingSchedulePeriod indicates the specific execution attribute value of the schedule, startPeriod indicates how many seconds after startSchedule, limit is the actual specific power limit value in watts, and numberPhases is the number of phases.

[0096] (2) Example of a charging pile sending a message (SetChargingProfileResponse) to CSMS:

[0097] {

[0098] "status":"Accepted"

[0099] }

[0100] Where: status is the response to the configuration request sent by CSMS, Accepted means accepted, Rejected means rejected;

[0101] For example, the status field in the response message can be used to inform the CSMS whether the charging pile accepts the configuration request. Accepted indicates that the charging pile has successfully received and approved the configuration and will execute the charging plan according to the request. Rejected indicates that the charging pile refuses to execute the configuration and the CSMS needs to adjust and resend the request.

[0102] The CSMS response message can confirm whether the charging pile has accurately parsed and processed the configuration instructions, thus avoiding configuration failure due to communication failure or data errors.

[0103] Optionally, if the charging station returns a "Rejected" response, the CSMS can trigger a retry mechanism or an alarm process to improve system robustness.

[0104] When configuration is accepted, the charging station will adjust its charging strategy according to the configuration details (such as power limits and time schedules). When configuration is rejected, CSMS can resend the revised request.

[0105] The charging pile power adjustment method based on OCPP provided in this embodiment of the invention can ensure the reliability and consistency of charging configuration.

[0106] Figure 4 The flowchart illustrates the power adjustment method combining OCPP2.0 smart charging and sampling information provided by this invention. Figure 4 As shown, the method includes:

[0107] When a user starts charging, the system collects data such as inlet temperature, outlet temperature, battery production time, number of battery charging cycles, current battery temperature, and charging gun head temperature.

[0108] If a smart charging configuration is received from a remote backend, the corresponding power limit is parsed.

[0109] The current output power is obtained by processing with a normalization function.

[0110] Determine whether local time-period power is enabled. If not, use the power calculated using normalization. If enabled, determine the minimum power value between the two.

[0111] The minimum power value is output and sent to the control board to limit the current charging power.

[0112] The power adjustment method provided by this invention, which combines OCPP2.0 smart charging and sampling information, calculates the local optimal power of the charging pile by collecting the temperature and battery information of the vehicle and charging pile, and combining it with the smart charging power limit issued by CSMS. This method prevents fires or damage to electrical components in charging piles and vehicles under high temperature environments and old battery conditions. In particular, with the arrival of high temperatures in various regions, it addresses the pain point of potential dangers during charging and ensures the safety of people and property.
