[0002] With the global popularization of electric vehicles, a large number of domestic charging pile companies are going overseas. Different regions have different charging standards, especially for the CHAdeMO protocol. As the CHAdeMO standard protocol is constantly iterated, charging pile companies need to be compatible with both new and old protocols. However, the traditional BMS (Battery Management System) simulator only supports a single protocol version. When conducting charging simulation tests, it is often necessary to purchase equipment repeatedly, which is costly and slow. This has become a major problem for the overseas expansion of charging piles. Summary of the Invention

Wherein, the second preset maximum demand current is more than twice the first preset maximum demand current, and the second preset maximum battery voltage is twice the first preset maximum battery voltage.

[0006] Optionally, in one embodiment of the present invention, step S2 includes the following steps: Step S21: When the charging protocol is identified as CHAdeMO charging protocol version 0.9 or CHAdeMO charging protocol version 1.2, determine whether the target charging pile is in charging mode based on the monitored charging operation status of the target charging pile. If yes, proceed to step S22; otherwise, determine that the required charging simulation current of the target charging pile is zero. Step S22: Obtain the available output current of the target charging pile, and determine the smaller of the available output current of the target charging pile and the first preset maximum demand current as the charging simulation current required by the target charging pile.

[0007] Optionally, in one embodiment of the present invention, step S2 includes the following steps: Step S23: When the charging protocol is identified as CHAdeMO charging protocol version 2.0, determine whether the target charging pile is in charging mode based on the monitored charging operation status of the target charging pile. If yes, proceed to step S24; otherwise, determine that the required charging simulation current of the target charging pile is zero. Step S24: Extract the charging current attribute of the target charging pile from the charging operation status of the target charging pile, wherein the charging current attribute indicates whether the target charging pile supports dynamic current control. Step S25: Determine the required charging simulation current for the target charging pile based on the electrical simulation parameters, the charging current attributes, and the pre-determined available output current of the target charging pile.

[0008] Optionally, in one embodiment of the present invention, step S25 includes the following steps: Step S251: When the charging current attribute indicates that the target charging pile supports dynamic current control, obtain the vehicle demand current corresponding to the target charging pile. Step S252: The smaller of the vehicle's required current and the available output current of the target charging pile is taken as the simulated charging current required by the target charging pile.

[0009] Optionally, in one embodiment of the present invention, step S25 includes the following steps: Step S253: When the charging current attribute indicates that the target charging pile does not support dynamic current control, the smaller of the available output current of the target charging pile and the second preset maximum demand current is used as the simulated charging current required by the target charging pile.

[0010] Optionally, in one embodiment of the present invention, the following steps are included before step S1: Step S4: Output CPD voltage through the configured CPD port so that the target charging pile samples the CPD voltage and switches to plug-in or unplug-in state depending on whether the CPD voltage is within the plug-in voltage range of the target charging pile.

Compared to existing technologies, this invention fully supports the same BMS simulator to simulate charging piles with different charging protocols, reducing the hardware and software costs of simulated charging, accelerating the development of charging pile applications, further improving the reliability of charging piles, and enhancing the user charging experience.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] It should be noted that although functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart.

[0017] Figure 1 This is a schematic diagram illustrating an application scenario of a BMS simulator for performing a charging pile simulation charging method, provided in an embodiment of the present invention.

[0018] like Figure 1 As shown, the BMS simulator is connected to the target charging station to enable interaction between the two.

[0019] It should be noted that the BMS simulator can, but is not limited to, connect to multiple charging piles simultaneously. When one of the charging piles needs to perform simulated charging, that charging pile becomes the target charging pile shown in this embodiment. In other words, there can be multiple target charging piles, and each target charging pile can be applied to the application scenario of the BMS simulator shown in this embodiment. To avoid redundancy, the following will focus on the interaction between the BMS simulator and a single target charging pile (i.e., Figure 1 The application scenario shown is described below.

[0020] More specifically, such as Figure 1 As shown, the target charging pile may include, but is not limited to, a TMU and a TCU. The TMU is the charging terminal unit, and the TCU is the centralized control unit. The TMU acts as the charging server, which communicates with the BMS simulator to receive or send relevant data interaction messages. The TCU acts as the background control terminal, which communicates with the TMU and obtains relevant data interaction messages from the TMU. It then reads information such as the charging protocol and charging requirements of the vehicle to be charged through the relevant data interaction messages. Based on this information, the target charging pile can adaptively charge the vehicle to be charged.

[0021] In one embodiment, the target charging pile may also include other related charging components or charging modules. By cooperating with the TMU, TCU and other related charging components or charging modules, the charging pile can operate stably and reliably, ensuring that it can simultaneously provide adaptive charging for multiple vehicles with different CHAdeMO charging protocols. In other words, the charging pile in the following embodiments can integrate the functions of the TMU, TCU and other related charging components or charging modules, thereby enabling the same charging pile to simultaneously provide adaptive charging for multiple vehicles with different CHAdeMO charging protocols. This will not be elaborated here.

[0022] In one embodiment, the charging protocol adapted to the target charging pile may be, but is not limited to, multiple. This embodiment mainly considers several types of CHAdeMO charging protocol. That is, the following embodiments are mainly based on CHAdeMO charging protocol version 0.9, CHAdeMO charging protocol version 1.2 and CHAdeMO charging protocol version 2.0 for description, but are not the only limitation.

[0023] In one embodiment, such as Figure 2 As shown, the BMS simulator may, but is not limited to, integrate a simulator control board, a meter module, and a load module. The meter module and the load module are both adapted to the simulator control board. The simulator control board, the meter module, and the load module are also connected to the charging gun socket of the target charging pile to achieve effective simulation control. The pins and connection methods of each module or unit are implemented using the layout methods in the relevant existing technologies, which are well known to those skilled in the art and will not be described in detail here.

[0024] The BMS simulator and application scenarios described in the embodiments of this invention are for the purpose of more clearly illustrating the technical solutions of the embodiments of this invention, and do not constitute a limitation on the technical solutions provided by the embodiments of this invention. Those skilled in the art will know that with the evolution of BMS simulators and the emergence of new application scenarios, the technical solutions provided by the embodiments of this invention are also applicable to similar technical problems.

[0025] It will be understood by those skilled in the art that Figure 1 or Figure 2 The BMS simulator shown does not constitute a limitation on the embodiments of the present invention and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0026] based on Figure 1 or Figure 2 The diagram shows an application scenario of the BMS simulator, and various embodiments of the charging pile simulation charging method of the present invention are proposed.

[0027] Figure 3 This is a flowchart illustrating a simulated charging method for a charging pile according to an embodiment of the present invention. Figure 3 As shown, this charging pile simulation charging method can be applied to, but is not limited to, [various applications]. Figure 1 or Figure 2 The BMS simulator shown includes, but is not limited to, steps S1 to S3.

[0028] Step S1: When the first interactive message carrying the charging protocol of the target charging pile is received from the target charging pile, the electrical simulation parameters matching the target charging pile are determined according to the charging protocol. In other words, when the BMS simulator receives the first interactive message, it means that the target charging pile is in the plug-in state and needs to be charged. Therefore, the first interactive message is sent to the BMS simulator to perform the interaction. Step S2: Determine the required charging simulation current for the target charging pile based on the electrical simulation parameters and the monitored charging operation status of the target charging pile. Step S3: In response to the first interactive message, send a second interactive message carrying the charging simulation current to the target charging pile. That is, by sending the second interactive message to the target charging pile, the target charging pile can adaptively simulate charging according to the required charging simulation current, so as to achieve a good and reliable simulated charging effect.

[0029] In this step, charging simulation of charging piles is implemented based on a BMS simulator. Upon receiving the first interactive message carrying the charging protocol sent by the target charging pile, the BMS simulator can determine the electrical simulation parameters matching the target charging pile according to the charging protocol. That is, regardless of the version of the charging protocol, the corresponding electrical simulation parameters can be configured. Then, based on the electrical simulation parameters and the monitored charging operation status of the target charging pile, the required charging simulation current of the target charging pile can be effectively and reliably determined, and returned to the target charging pile through an interactive message, enabling it to achieve orderly and stable simulated charging. Compared with related existing technologies, this fully supports the same BMS simulator to simulate charging piles with different charging protocols, which can reduce the hardware and software costs of simulated charging, improve the development progress of charging pile applications, further enhance the reliability of charging piles, and meet the user's charging experience.

[0030] In one embodiment of the present invention, before step S1, the following steps may be included, but are not limited to: Step S4: Output CPD voltage through the configured CPD port so that the target charging pile samples the CPD voltage and switches to plug-in or unplug-in state depending on whether the CPD voltage is within the plug-in voltage range of the target charging pile.

[0031] Specifically, such as Figure 4 As shown, the CPD port of the BMS simulator always outputs the CPD voltage. The target charging pile detects the plug-in / plug-out signal. That is, if the TMU detects that the sampled CPD voltage is within the preset plug-in voltage range, it switches to the plug-in state; otherwise, it switches to the unplug state. Correspondingly, when switching to the plug-in state, it sends a first interactive message carrying its own charging protocol to the BMS simulator.

[0032] In one embodiment of the present invention, step S1 may include, but is not limited to, the following steps: Step S11: When the charging protocol is identified as CHAdeMO charging protocol version 0.9 or CHAdeMO charging protocol version 1.2, the electrical simulation parameters matched with the target charging pile are determined to be the first preset maximum demand current and the first preset maximum battery voltage. or, Step S12: When the charging protocol is identified as CHAdeMO charging protocol version 2.0, the electrical simulation parameters matched with the target charging pile are determined to be the second preset maximum demand current and the second preset maximum battery voltage. Among them, the second preset maximum demand current is more than twice the first preset maximum demand current, and the second preset maximum battery voltage is twice the first preset maximum battery voltage.

[0033] Specifically, such as Figure 5As shown, when the charging protocol is identified as CHAdeMO charging protocol version 0.9 or CHAdeMO charging protocol version 1.2, meaning the target charging pile currently supports CHAdeMO charging protocol version 0.9 or CHAdeMO charging protocol version 1.2, the BMS simulator confirms the electrical simulation parameters provided by the current BMS simulator based on this, and modifies its own maximum battery voltage to the first preset maximum battery voltage, i.e., 500V, and modifies the maximum required current to the first preset maximum required current, i.e., 125A; if the target charging pile currently supports CHAdeMO charging protocol version 2.0, the simulator sends the charging protocol as version 2.0, and modifies its own maximum battery voltage to the second preset maximum battery voltage, i.e., 1000V, and modifies the maximum required current to the second preset maximum required current, i.e., 400A.

[0034] like Figure 6 As shown, in one embodiment of the present invention, step S2 may include, but is not limited to, the following steps: Step S21: When the charging protocol is identified as CHAdeMO charging protocol version 0.9 or CHAdeMO charging protocol version 1.2, determine whether the target charging pile is in charging mode based on the monitored charging operation status of the target charging pile. If yes, proceed to step S22; otherwise, determine that the required charging simulation current of the target charging pile is zero. Step S22: Obtain the available output current of the target charging pile, and determine the smaller of the available output current of the target charging pile and the first preset maximum demand current as the charging simulation current required by the target charging pile.

[0035] Specifically, such as Figure 7 As shown, when the charging protocol is identified as CHAdeMO charging protocol version 0.9 or CHAdeMO charging protocol version 1.2, the BMS simulator can reply with its own protocol as CHAdeMO charging protocol version 0.9 or CHAdeMO charging protocol version 1.2. Then, based on the charging operation status of the target charging pile, it determines whether the target charging pile is in charging mode, and determines the corresponding charging simulation current based on whether it is in charging mode. The whole process takes into account the impact of the charging simulation current caused by the difference in charging protocols, and also determines the available output current of the target charging pile in combination with the real-time available current of the target charging pile. Finally, the smaller of the available output current of the target charging pile and the first preset maximum demand current can be determined as the charging simulation current required by the target charging pile. The available output current of the target charging pile can be set or monitored by the charging pile's own control module or unit, which will not be elaborated here.

[0036] like Figure 8 As shown, in another embodiment of the present invention, step S2 may include, but is not limited to, the following steps: Step S23: When the charging protocol is identified as CHAdeMO charging protocol version 2.0, determine whether the target charging pile is in charging mode based on the monitored charging operation status of the target charging pile. If yes, proceed to step S24; otherwise, determine that the required charging simulation current of the target charging pile is zero. Step S24: Extract the charging current attribute of the target charging pile from the charging operation status of the target charging pile, wherein the charging current attribute indicates whether the target charging pile supports dynamic current control. Step S25: Determine the required charging simulation current for the target charging pile based on the electrical simulation parameters, charging current attributes, and the pre-determined available output current of the target charging pile.

[0037] In this step, the charging operation status of the target charging pile is monitored to determine whether the target charging pile is in charging mode. Then, based on the charging current attributes of the target charging pile, it is determined whether the target charging pile supports dynamic current control. Combining the dynamic current control status of the target charging pile, the corresponding electrical simulation parameters, and the available output current, the required charging simulation current of the target charging pile can be accurately and effectively determined. The overall solution is simple, convenient, low-cost, and easy to implement.

[0038] In one embodiment, whether current dynamic control is supported may refer to, but is not limited to, whether high current control and dynamic control are supported simultaneously.

[0039] like Figure 9 As shown, in one embodiment of the present invention, step S25 may include, but is not limited to, the following steps: Step S251: When the charging current attribute indicates that the target charging pile supports dynamic current control, obtain the vehicle demand current corresponding to the target charging pile. The vehicle demand current is the real-time current required by the vehicle to be charged. The value may be different for different charging vehicles. Step S252: Use the smaller of the vehicle's required current and the available output current of the target charging station as the simulated charging current required by the target charging station.

[0040] In another embodiment of the present invention, step S25 may include, but is not limited to, the following steps: Step S253: When the charging current attribute indicates that the target charging pile does not support dynamic current control, the smaller of the available output current of the target charging pile and the second preset maximum demand current is used as the simulated charging current required by the target charging pile.

[0041] Specifically, such as Figure 10As shown, if the charging protocol is confirmed to be CHAdeMO charging protocol version 2.0, the maximum battery voltage of 1000V is sent to determine whether the charging process has started. If so, it is determined whether the target charging pile supports high current control and dynamic control. Otherwise, the vehicle demand current extension frame corresponding to the target charging pile is set to zero. Furthermore, regarding whether the target charging pile supports high current control and dynamic control, if it does, the BMS simulator sends the vehicle's required current extended frame and compares it with the charging pile's available output current extended frame, ultimately selecting the smaller one to send, i.e., outputting the corresponding maximum required current extended frame as 400A; conversely, if it does not support it, it sends the vehicle's required current and compares it with the charging pile's available output current, taking the smaller one, and outputting the corresponding maximum required current as 125A. The entire process described above can be achieved by dynamically adjusting the required voltage and current of the BMS simulator through PC host computer software. If it is necessary to test the actual current output, simply use a Japanese to Chinese power adapter, plug it into a Chinese standard load gun socket, and then connect the load corresponding to the required current after charging to test the actual output. After the simulated charging is completed, the BMS simulator normally sends the corresponding stop message, disconnects the VCP signal, restores the initial parameter values, and waits for the next simulated charging. In summary, the charging pile simulation charging method provided in this embodiment of the invention has the following advantages: It has broad compatibility, supports dynamic identification and conversion of multiple protocols, can achieve accurate protocol identification, and achieve seamless switching in all scenarios; The efficiency of charging pile testing has been significantly optimized. By automatically loading electrical parameters through a dynamic protocol, protection issues triggered by parameter mismatches are resolved, and the charging pile's compatibility with different protocols and charging success rate are improved. Cost reduction: The use of a single set of software and hardware instead of multiple versions of software and hardware significantly reduces the cost for charging pile companies to purchase different protocol simulators. Its advanced technology means that even with the latest CHAdeMO charging protocol standard, no hardware modifications are required, reducing expansion costs.
