[0001] The utility model relates to charging device technical field, concretely relates to a car charging simulator. BACKGROUND

[0002] With the enhancement of global awareness of sustainable development and environmental protection, the new energy vehicle (NEVs) industry has ushered in an unprecedented development opportunity. Electric vehicles (EVs) as the representative of new energy vehicles, its market demand continues to grow, driving the entire industry chain technology innovation and expansion. In this context, the charging facilities of electric vehicles have become one of the key infrastructures, and their construction and maintenance directly affect the popularization of electric vehicles and user experience. Therefore, the innovation and optimization of charging technology have become an important branch in the field of new energy vehicles, involving charging efficiency, safety, convenience and other aspects. In this big background, the present application focuses on the sub-field of charging equipment debugging and maintenance, aiming to improve the operation efficiency and reliability of charging facilities through technological innovation.

[0003] In the existing new energy vehicle charging equipment debugging and maintenance practice, technicians usually need to carry multiple devices and tools, such as charging machine units (CMU), electric vehicle charging control units (electric vehicle charging controllers), air switches and various cables, etc., to simulate the actual charging environment for on-site debugging. Although the use of these devices and tools meets the debugging needs to some extent, it also exposes a series of problems:

[0004] Carrying inconvenience: due to the need to carry a variety of debugging devices and cables, the on-site debugging preparation work becomes complex and time-consuming, which is not conducive to quick response and handling of on-site problems.

[0005] Complex construction process: when setting up the debugging environment on site, a lot of wiring and device connection work needs to be done, which not only increases the workload, but also increases the risk of errors, affecting the efficiency of debugging.

[0006] Difficult on-site management: due to the messy placement of on-site debugging devices and cables, it is difficult to meet the standards of on-site management, which not only affects the safety and efficiency of work, but also is not conducive to the cleanliness and order of the maintenance site.

[0007] High labor cost: traditional debugging methods require a lot of manpower, especially in wiring and device setup, which undoubtedly increases the labor cost of debugging.

[0008] Low efficiency: due to the above problems, the traditional debugging method is low in efficiency in actual operation, which cannot meet the growing market demand and the requirement of high efficiency.

[0009] Therefore, the existing debugging means cannot meet the modernization demand of new energy automobile charging equipment debugging and maintenance, and an efficient and convenient solution is urgently needed to improve the efficiency and convenience of debugging work. Practical new type content

[0010] The utility model aims at providing a kind of automobile charger simulator to overcome the technical problems of inconvenient equipment carrying, complex debugging environment building and difficult on-site management in the process of existing charging equipment debugging and maintenance.

[0011] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0012] An automobile charging simulator includes a simulator case, which serves as the main structure of the simulator and integrates various components required for debugging charging equipment inside, providing an operating interface and physical protection for internal components. The top of the simulator case is an operating panel that allows users to perform operations such as power connection, status monitoring, parameter setting, and charging connection. The simulator case is internally arranged with a control device and a human-computer interaction component, and users can control the human-computer interaction component through the operating panel to debug the charging equipment.

[0013] The human-computer interaction component includes a power socket and several indicator lights, which are connected to the power socket respectively. When using the automobile charging simulator, connect the external power supply to the power socket to power the simulator, and display the working status of the internal components of the simulator through the indicator lights. The human-computer interaction component also includes a CAN (Controller Area Network) analyzer, a gun seat, and an electrical protection device. The CAN analyzer is connected to the control device and is used to set and analyze communication signals on the CAN bus, allowing the debugging personnel to set charging parameters and analyze communication signals. The gun seat is connected to the external charging gun as a connection point for the charging gun, simulating the physical connection in the real charging process. The electrical protection device is connected in series with the power circuit to control the on-off of the power supply.

[0014] Further, the simulator case includes a simulator shell and a simulator cover plate, which are connected on one side. The simulator shell constitutes the main part of the simulator case, providing structural support and physical protection. The simulator cover plate is placed above the simulator shell, providing physical protection for the internal control device and serving as a platform for operating the human-computer interaction component, allowing users to operate the human-computer interaction component through the cover plate while protecting the internal control device below the cover plate.

[0015] Furthermore, the control device includes a TMU (Terminal Management Unit) control panel and an Electric Vehicle Charge Controller (EVCC), each housed within the simulator cover. The TMU control panel is responsible for system control, including charge status detection and system control. It manages the charging process, including current and voltage control and fault detection. The EVCC is responsible for charge status detection, monitoring, and controlling the charging process to ensure safe and efficient charging.

[0016] Furthermore, the TMU control board and the electric vehicle charging controller are respectively connected to an auxiliary power source, which supplies power to the entire control system of the simulator and ensures the normal operation of all electronic components inside the simulator.

[0017] Furthermore, the CAN analyzer is connected to the TMU control board via a CAN bus. The CAN analyzer and the TMU control board exchange information, data, and signals via the CAN bus. The CAN analyzer allows the user to set charging parameters, such as charging current and voltage. These parameters are sent to the TMU control board via the CAN bus, and the TMU control board implements these settings. The TMU control board can also send information such as charging status and battery status back to the CAN analyzer for user monitoring.

[0018] Furthermore, the gun mount and the TMU control panel are respectively connected to the electric vehicle charging controller.

[0019] Furthermore, the simulator housing is connected to the simulator cover by a hinge, allowing the simulator cover to be rotated open, making it easy to open and close the simulator and to facilitate maintenance and inspection of the simulator's internal components.

[0020] Furthermore, the indicator lights include a power indicator light, an operation indicator light, and a fault indicator light. These respectively indicate the simulator's power status, operation status, and fault conditions. When the simulator is powered on, the power indicator light illuminates, clearly indicating to the user that the simulator is powered on and ready. When the simulator is charging or in other operating states, the operation indicator light illuminates, indicating to the user that the simulator is functioning properly. When the simulator detects an internal communication signal anomaly or other fault, the fault indicator light illuminates, prompting the user to check and resolve the issue.

[0021] Furthermore, handles are installed on both sides of the simulator chassis to provide gripping points when the simulator is carried, making it easier for debugging personnel to carry the simulator.

[0022] Furthermore, the electrical protection device includes an air switch, which automatically disconnects the circuit when an overload or short circuit occurs in the circuit, thereby protecting the circuit and equipment from damage.

[0023] Compared with the prior art, the automobile charging simulator has the following beneficial technical effects:

[0024] The automobile charging simulator integrates the devices and components required for debugging in a compact simulator case, greatly improving the portability of the equipment and reducing the carrying burden of the debugging personnel. At the same time, the rapid linking design of the simulator simplifies the on-site debugging process, saves labor costs, and significantly improves work efficiency. The modular and integrated design also makes the on-site management more standardized, improves the neatness of the site, and meets the requirements of on-site management.

[0025] In addition, the operation panel of the simulator provides an intuitive user interface, making the power connection, state monitoring, parameter setting, and charging connection operations more convenient, and improving the user experience. The integrated electrical protection device such as the air switch enhances the safety during use and can automatically disconnect the circuit when the circuit is overloaded or short-circuited, protecting the circuit and equipment from damage. The hinge-connected shell and cover design makes it easier to maintain and repair the internal components, shortens the maintenance time, and improves the maintenance efficiency.

[0026] The simulator can also flexibly set charging parameters to meet the needs of different charging scenarios and can monitor the charging status and battery status in real time, providing intuitive feedback to make the charging process more transparent. Its design takes into account the compatibility with different charging equipment and has expandability to adapt to future technology upgrades and new needs. The compact integrated design also makes the simulator adaptable to various environmental conditions, whether indoors or outdoors, and can work stably, showing strong environmental adaptability.

[0027] In summary, the automobile charging simulator provided by the present application has significant improvements in portability, work efficiency, on-site management, safety, and other aspects compared to the prior art, providing a more efficient, safe, and convenient solution for the debugging and maintenance of new energy automobile charging equipment.
