Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle battery training simulation technology, specifically a new energy vehicle power battery pack simulation device based on virtual reality technology. Background Technology

[0002] With the continuous development of the automotive battery training simulation field, existing automotive battery training simulation products have been widely used. However, these products still have some problems in practical use. For example, existing automotive battery training simulations often have limitations, such as the inability to provide battery performance simulations under real driving conditions. This results in limited training effectiveness, making it difficult for trainees to fully understand the performance of new energy vehicle batteries under different operating conditions.

[0003] To address these issues, some attempts have been made, such as introducing virtual reality technology to enhance the training experience. While these methods have improved aspects to some extent, they still have limitations; for example, the accuracy and real-time performance of virtual reality technology in simulating real battery performance still need improvement.

[0004] Specifically, a search revealed a new energy vehicle road condition simulation teaching platform with publication number CN210627539U, published on May 26, 2020. This design combines a pure electric vehicle with a road surface simulation test bench. While it can provide some road condition simulation, the lack of real-time feedback on battery performance under complex road conditions results in insufficient accuracy when simulating specific driving conditions. Therefore, this design cannot meet the in-depth teaching needs for assessing the performance of new energy vehicle batteries under complex road conditions.

[0005] A search revealed a publicly available training device for cascaded utilization of ternary lithium-ion power batteries, with publication number CN213424348U and publication date June 11, 2021. This product utilizes a cascaded battery pack assembly. While it can demonstrate the structural principles of power battery packs and perform charge / discharge training, the lack of virtual reality technology limits its ability to simulate battery performance under real-world driving conditions, making it difficult to provide an immersive training experience. Therefore, this design fails to meet the needs of training on intelligent and highly realistic new energy vehicle batteries.

[0006] The aforementioned problems indicate that current automotive battery training simulation equipment on the market is insufficient to effectively meet the in-depth teaching needs regarding the performance of new energy vehicle batteries under complex operating conditions. Therefore, this invention provides a new energy vehicle power battery pack simulation device based on virtual reality technology to overcome these shortcomings and offer a more intelligent, efficient, and adaptable solution for changing environments.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: Battery performance simulation is achieved through the linkage of the power battery pack simulation module and the operating condition feedback module.

[0034] Please see the appendix Figure 1 and attached Figure 2 This embodiment provides a simulation device for a new energy vehicle power battery pack based on virtual reality technology, including a simulation platform 1, a virtual reality system 2, a power battery pack simulation module 3, a working condition feedback module 4, and a data processing unit 5. Through the collaborative work of these modules, the device achieves accurate simulation of the performance of a new energy vehicle power battery under different driving conditions.

[0035] First, the power battery pack simulation module 3 includes multiple detachable battery cell modules 31, which are connected to the simulation platform 1 via pluggable connectors 32. The pluggable connectors 32 not only provide stable electrical connection terminals but also include data transmission ports for transmitting real-time status data of each battery cell 31, such as temperature, voltage, and charge / discharge status. This design allows trainees to replace different types or specifications of battery cells according to their training needs, thereby experiencing the performance of different types of power batteries in actual driving.

[0036] Each battery cell 31 is externally encased in a temperature sensor 33, which monitors its temperature changes in real time and transmits the data to a temperature regulation unit 34. The temperature regulation unit 34 includes a heater 35 and a cooler 36, connected to each battery cell 31 via a heat pipe 37. When one or more battery cells are detected to be overheating, the heater 35 stops operating, while the cooler 36 activates, rapidly reducing the temperature through the heat transfer medium to ensure the entire system operates safely.

[0037] Furthermore, the charge / discharge control unit 38 controls the charge / discharge pulses of each battery cell 31 via the charging circuit 39 and the discharging circuit 40, and monitors the current status via the built-in current sensor 41. This data is sent in real time to the data processing unit 5, which analyzes it and feeds it back to the virtual reality system 2, allowing the learner to intuitively see the impact of different driving behaviors (such as rapid acceleration or prolonged low-speed driving) on ​​the power system's energy consumption and driving range.

[0038] Please see the appendix Figure 3 The working condition feedback module 4 further enhances the system's ability to reproduce vehicle performance under complex driving environments. The road condition simulation unit 42 includes a vibration platform 45 and a tilt adjustment mechanism 46. The vibration platform 45 is connected to the simulation platform 1 through multiple telescopic push rods to reproduce the vibration effects of various road conditions (such as bumpy roads or flat highways). The tilt adjustment mechanism 46 is driven by a hydraulic cylinder 55 and connected to the platform through a hinge structure 56. It can adjust the tilt angle of the entire platform according to the slope angle, thereby realistically reproducing the load differences caused by the change in the vehicle's center of gravity when driving uphill or downhill.

[0039] The vehicle speed simulation unit 43 monitors the data generated by the trainee operating the vehicle in the virtual environment through the vehicle speed sensor 47, and the vehicle speed feedback motor 48 dynamically adjusts the vibration frequency and tilt angle based on this data. For example, when the trainee accelerates rapidly in the virtual environment, the vehicle speed feedback mechanism will immediately increase the vibration frequency and slightly raise the height of the front end of the platform to simulate the increased force on the rear wheels when a real vehicle starts quickly.

[0040] The load simulation unit 44 uses the load sensor 49 to detect changes in vehicle load during virtual driving, such as an increase in the number of passengers or a change in cargo weight, and adjusts the power output through the load regulator 50. This function allows trainees to experience the significant impact of different load conditions on the vehicle's range and energy efficiency, thereby gaining a more comprehensive understanding of the performance of new energy vehicles in real-world usage scenarios.

[0041] In summary, this embodiment achieves accurate reproduction of the power system performance under complex operating conditions of new energy vehicles through data linkage between the power battery pack simulation module 3 and the operating condition feedback module 4, providing trainees with an immersive and highly interactive training experience. Furthermore, the standardized interface design between the various sub-components ensures the entire system has excellent scalability and ease of maintenance.

[0042] Example 2: Comprehensive Simulation of the Impact of Environmental Factors on the Performance of New Energy Vehicles

[0043] Please see the appendix Figure 4 and attached Figure 5 This embodiment further introduces an environmental factor simulation function to better simulate the problems that new energy vehicles may encounter when operating under extreme weather conditions (such as high temperature, high humidity, or strong wind). The device adds an environmental simulation unit 51, which includes a wind speed simulator 52, a temperature simulator 53, and a humidity simulator 54. These are used to generate data inputs under different wind speed, temperature, and humidity conditions, and send this information to the data processing unit 5 in real time for comprehensive analysis and processing.

[0044] For example, when the wind speed is high, the wind speed simulator 52 generates corresponding visual effects in the virtual reality headset 21 and simultaneously sends a signal to the power management system (BMS), causing the BMS to automatically adjust its heat dissipation strategy. In this situation, the heater 35 may reduce its operating time, while the cooler 36 needs to remain on for an extended period to cope with the additional heat dissipation demands caused by the high external wind speed. Similarly, in high humidity environments, the humidity sensor 54 triggers an internal moisture-proof mechanism, appropriately reducing power output to prevent short-circuit risks caused by moisture intrusion. Furthermore, under high temperature conditions, the temperature control device 53 will force the BMS to implement current-limiting measures to prevent excessively high power output from causing rapid lithium-ion degradation or even an explosion hazard.

[0045] Please see the appendix Figure 6 To further improve simulation accuracy, this device is also equipped with an automatic pressure balancing mechanism. This mechanism mainly relies on pressure sensors mounted on hydraulic cylinder 55 and a small servo motor located at the hinge structure 56. When the external air pressure suddenly changes (such as a sudden drop in atmospheric pressure before a rainstorm), the servo motor quickly adjusts the position of hydraulic cylinder 55, thereby changing the tilt angle of the entire platform, making the internal airflow smoother and effectively preventing damage to internal electronic equipment due to poor airtightness. At the same time, this design also reserves sufficient space for new functions that may be added in the future, such as integrating more types of sensors to achieve broader application scenario coverage and other innovative directions.

[0046] In summary, by introducing multi-dimensional environmental parameter simulation, this invention significantly improves the ability of the entire training system to reproduce complex real-world scenarios. It not only helps trainees master basic operating skills but also allows them to familiarize themselves with how to properly deal with emergencies under extreme weather conditions—a point that is particularly important for those who will be engaged in the operation and maintenance of new energy vehicles in the future.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
