This function is crucial for optimizing charging strategies, improving charging efficiency, and extending battery life. Furthermore, the automotive charging simulator has excellent fault simulation capabilities. It can simulate various fault conditions that may occur during charging, such as communication failures, power supply failures, and battery failures, helping engineers to identify and fix potential problems in the early stages of product design, thus ensuring the stability and reliability of the charging equipment in actual operation.

[0004] Therefore, a new energy vehicle charging simulator is provided that balances improving user convenience with product reliability. Utility Model Content

[0005] The purpose of this invention is to provide a new energy vehicle charging simulator to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A new energy vehicle charging simulator includes a closable lid, a housing, and a bottom. The lid, housing, and bottom form a closed structure to protect the internal electronic components and wiring. An operation panel is fixed to the upper edge of the housing. A U-shaped connector is located in the upper left corner of the operation panel, used to connect to the charging interface of an electric vehicle for charging. A CAN bus interface is located in the upper right corner of the operation panel, used to connect to a CAN communication box for communication and data exchange with the electric vehicle. An air switch is located below the U-shaped connector, used to control the power supply of the entire charging simulator. A charging gun holder is located below the CAN bus interface, used to hold the charging gun for easy charging operation. A status indicator light is also located in the center of the operation panel.

[0008] Furthermore, the control panel is fixed to the upper edge of the housing by multiple flat-head screws. The control panel can be removed from the bottom of the housing. This fixing method is not only stable and reliable, but also easy to disassemble, allowing the device to be operated outside the housing during assembly and disassembly, which can reduce assembly difficulty and significantly improve assembly efficiency.

[0009] Furthermore, the status indicator lights are used to indicate the current status of the charging simulator. There are three status indicator lights: a power light, a running light, and a fault light. This arrangement allows users to intuitively understand the current status of the charging simulator. When a fault or abnormality occurs, the fault light will illuminate, reminding the user to troubleshoot and handle the issue promptly. This design facilitates quick problem location and appropriate solutions for users.

[0010] Furthermore, the power indicator light is blue, indicating that the charging simulator is powered on; the operation indicator light is green, indicating that the charging simulator is working normally; and the fault indicator light is red, indicating that the charging simulator has malfunctioned or is abnormal.

[0011] Furthermore, adjusting the air switch upwards turns the power on, and adjusting it downwards turns the power off.

[0012] Furthermore, the outer wall of the box is provided with multiple reinforcing ribs. By increasing the overall rigidity of the box, the reinforcing ribs can effectively prevent the box from deforming or twisting when subjected to external forces.

[0013] Furthermore, a TMU control board is provided at the upper right corner of the bottom of the box, an auxiliary power source is provided at the lower right of the TMU control board, and an EVCC is provided to the left of the auxiliary power source.

[0014] Furthermore, the bottom of the box is equipped with a pull rod to facilitate the user's movement and carrying of the charging simulator.

[0015] Furthermore, a pair of casters are provided on the bottom edge of the enclosure, allowing the charging simulator to be easily moved and positioned.

[0016] Furthermore, the enclosure is made of plastic, which reduces the weight of the equipment, lowers production costs, and meets environmental protection requirements.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] This utility model provides a new energy vehicle charging simulator that integrates operating and display elements into a single operating panel. During operation, it can simultaneously handle multiple operations and display observations, effectively improving human-computer interaction efficiency. By optimizing the layout and selection of internal components, the number of components is reduced and the overall structural design is improved without affecting equipment performance, thus enhancing cost-effectiveness. All internal components are mounted on the operating panel, which can be removed from the housing. This allows for operation without housing during component assembly and disassembly, reducing assembly difficulty and significantly improving assembly efficiency. The closable housing structure allows the cover to be closed when not in operation to prevent scratches on the operating panel or accidental activation, thereby ensuring the equipment's lifespan. The new energy vehicle charging simulator proposed in this utility model features a simple and clear overall design, making it easy to operate. Users can easily control the simulator's power on / off and set charging parameters. This design enhances the user experience, making the charging simulator easier to promote and apply, and improving user convenience and product reliability.

[0019] Specifically, the new energy vehicle charging simulator adopts a trolley case design. During transport, the simulator is moved by pulling the case handle and using casters at the bottom. Furthermore, the case is made of lightweight plastic, thus greatly saving manpower. Attached Figure Description

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

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] This utility model provides a new energy vehicle charging simulator that not only satisfies the need for ease of use but also improves the reliability of the equipment and effectively increases work efficiency.

[0029] See Figures 1 to 5A new energy vehicle charging simulator is disclosed, in which the connections between its various components are tight and reasonable, ensuring the stability and functionality of the equipment. It includes a closable cover 1, a housing 2, and a bottom. The cover 1 and housing 2 are fixed together on one side by fasteners (such as screws), while the other side can be opened and closed, forming a closed space to protect the internal electronic components and circuits. The housing 2 has a large interior space for an operation panel 4, which is fixed to the upper edge of the housing 2 by multiple flat-head screws 5. The upper left corner of the operation panel 4 has a triangular connector 6 for connecting to the charging interface of an electric vehicle to enable charging. The upper right corner of the operation panel 4 has a CAN box interface 9 for connecting to a CAN communication box to achieve communication and data exchange with the electric vehicle. Below the triangular connector 6 is an air switch 7, which controls the power supply of the entire charging simulator. When the air switch 7 is adjusted upwards to (ON), the power is on; when the air switch 7 is adjusted downwards to (OFF), the power is off. Below the CAN box interface 9 is a charging gun holder 8, used to hold the charging gun for easy charging operation. A status indicator light 10 is also located in the center of the operation panel 4. This status indicator light 10 indicates the current status of the charging simulator. There are three status indicator lights: a power indicator (PWR), a running indicator (RUN), and a fault indicator (FLT). When a fault or abnormality occurs, the fault indicator light will illuminate, reminding the user to troubleshoot and handle the issue promptly. This design facilitates quick problem location and appropriate solutions. The power indicator (PWR) illuminates in blue, indicating that the charging simulator is powered on; the running indicator (RUN) illuminates in green, indicating that the charging simulator is working normally; and the fault indicator (FLT) illuminates in red, indicating that the charging simulator has malfunctioned or is abnormal. All the simulator's operating and display components are integrated into the operation panel 4, resulting in a simple and clear structure. Assembly or maintenance can be performed without the enclosure 2, thus improving efficiency.

[0030] Meanwhile, a TMU control board 11 is located on the upper right corner of the back of the operation panel 4. An auxiliary power source 12 is located on the lower right of the TMU control board 11, and an EVCC 13 is located on the left side of the auxiliary power source 12. The auxiliary power source 12 and the EVCC 13 are mounted on the back of the operation panel 4 through sheet metal parts. The TMU control board 11 is mainly used for remote communication and management of the vehicle, the EVCC 13 is mainly used for communication control during the charging process of electric vehicles, and the auxiliary power source 12 can provide power to the control system.

[0031] In some preferred embodiments of this utility model, the outer wall of the box 2 is provided with a plurality of reinforcing ribs 14. By increasing the overall rigidity of the box 2, the reinforcing ribs 14 can effectively prevent the box 2 from deforming or twisting when subjected to external forces. The reinforcing ribs 14 can guide the stress to be distributed more evenly inside the box 2, thereby avoiding excessive stress concentration in certain areas and extending the service life of the box 2.

[0032] In some preferred embodiments of this utility model, the bottom of the box is provided with a pull rod 15. The design of the pull rod 15 allows users to easily lift and drag the charging simulator, which greatly improves work efficiency, especially in scenarios where frequent movement of the test equipment is required. A pair of casters 3 are provided on the bottom edge of the box 2. The casters 3 allow the charging simulator to slide easily on the ground. Users can quickly move the equipment to a designated position as needed. When the charging simulator needs to be fixed in a certain position for testing, the casters 3 (especially those with locking function) can provide stable support to prevent the equipment from moving or tilting during testing. The box 2 is made of plastic material, which is lighter than metal material. This significantly reduces the overall weight of the charging simulator, making it easy to carry and move. The plastic material has good corrosion resistance and insulation, which can protect the electronic components inside the charging simulator from external environmental corrosion and interference.

[0033] Work process:

[0034] During operation, connect the power cord of the charging simulator to the T-shaped connector 6 to provide power to the simulator. Turn the air switch 7 to the "ON" position. At this time, the internal circuitry of the simulator is activated, preparing to enter the working state. When the power is successfully connected, the blue "PWR (Power)" light in the status indicator 10 will illuminate. This indicates that the simulator has successfully received power and is in standby mode. Connect the charging gun head to the charging station 8 and start charging. At this time, the green "RUN (Run)" light in the status indicator 10 will illuminate, indicating that the simulator is running normally and simulating charging. If the red "FLT (Fault)" light in the status indicator illuminates, check for connection problems between the EVCC13 and the simulation board. This device supports modification of parameters such as charging voltage and charging current. To modify these parameters, a computer needs to be connected to the CAN box interface 9. Using software tools on the computer, users can easily modify and expand these parameters to meet different testing needs.
