A recent industry study is urging the electric vehicle sector to move beyond technical claims and warranty language when addressing public anxiety over spontaneous combustion, arguing that trust must be rebuilt through visible evidence, interactive verification, and transparent data. The research, conducted by a team affiliated with Shunde Polytechnic and the Foshan City Shunde District Fire and Rescue Brigade, places ordinary consumers at the center of the electric vehicle safety debate. Rather than focusing only on battery chemistry, thermal runaway mechanisms, or insurance products, the study examines how electric vehicle brands communicate safety at the retail level and how consumers can be given a clearer, more tangible understanding of battery operating conditions.
The research arrives at a sensitive moment for the electric vehicle market. As ownership rises quickly, reported fire incidents and consumer complaints have created a public trust challenge that extends beyond individual vehicle models. The study cites statistics showing that from 2018 to November 2024, 1,730 electric vehicle fire accidents were reported nationwide. It also notes that in consumer complaint data for electric vehicles, power battery failures, overstated range and power interruption, and slow charging have become major complaint points, accounting for 85 percent of such complaint information. For the electric vehicle industry, these figures are not merely technical indicators. They shape how buyers perceive risk, how sales staff respond to questions, and how the public evaluates the credibility of safety promises.
The study argues that the electric vehicle sector has reached a stage where engineering improvements alone are insufficient. A vehicle may be equipped with advanced thermal management, battery monitoring, and structural protection, but if consumers cannot perceive or verify those systems, trust remains fragile. The research therefore proposes two connected trust reconstruction paths: first, a battery status visualization system that turns temperature, voltage, and current data into a clear, real-time display; second, a thermal management experience space where consumers can operate equipment, observe safety responses, and validate technical claims through direct interaction. Together, these measures form a full-chain mechanism described by the study as dynamic monitoring, scenario verification, and data transparency.
1. A Trust Crisis Shaped by Rising Electric Vehicle Ownership and Visible Fire Risk
The study frames the electric vehicle trust crisis as a problem of perception as much as a problem of engineering. Spontaneous combustion incidents are relatively rare in the context of a growing vehicle population, but each high-profile fire can amplify public concern and cast doubt on the entire electric vehicle category. The research notes that social media discussion has reflected deep anxiety about electric vehicle safety, with online humor and skepticism becoming part of the broader public conversation. For many consumers, the question is not whether electric vehicle batteries are tested in laboratories, but whether those tests have any meaning in daily use, in extreme weather, during fast charging, or after a collision.
This gap between laboratory assurance and public perception is central to the study. The electric vehicle market has invested heavily in battery safety research, thermal management design, and quality control. Yet the research suggests that these efforts are not always translated into consumer-facing experiences. When a buyer walks into a dealership, safety may be communicated through certificates, warranty terms, or verbal assurances rather than through visible demonstrations of how the battery behaves, how heat is controlled, or how protection systems respond. The result is a credibility gap that can persist even when the underlying electric vehicle technology is robust.
The study also points to the broader complaint landscape. Power battery faults, range overstatement, power interruption, and slow charging are not identical to fire risk, but they contribute to a general sense of uncertainty around electric vehicle reliability. When consumers already have concerns about charging speed and range, a fire incident can become a symbol of deeper technological anxiety. The research therefore treats public trust as a systemic issue that involves vehicle design, retail communication, after-sales support, emergency response knowledge, and data disclosure.
2. Study Scope: Looking Beyond Engineering to Consumer Cognition
The research reviews existing approaches to electric vehicle safety from three main directions: technical improvement, accident prevention, and insurance mechanisms. Previous work has examined high-voltage wiring contact failure, battery pack structural damage, charging system loss of control, and other technical defects. Other studies have focused on thermal runaway mechanisms and proposed improvements in cell materials, cooling system optimization, and early warning systems. Research on emergency response has examined responsibility levels, high-voltage technician certification, and standardized operating procedures. Insurance studies have compared warranty policies and identified gaps in electric vehicle battery coverage.
However, the study argues that relatively little attention has been paid to the consumer’s technical cognition. The research therefore shifts the focus from engineers and regulators to ordinary electric vehicle users and dealership visitors. It asks how battery status can be made visible, how thermal management can be experienced rather than merely described, and how data can be used to close the gap between safety claims and public belief. This consumer-centered approach is presented as a necessary complement to technical and regulatory measures, not a replacement for them.
The field research covered 30 electric vehicle sales stores in Guangzhou, Foshan, and Dongguan. The study examined safety system displays, sales service practices, experience space construction, and feedback from sales personnel. The sample is focused on three cities in the Pearl River Delta, but the findings offer a useful view of how electric vehicle safety is communicated at the retail level. The research identifies a clear inconsistency: while electric vehicle manufacturers emphasize safety in marketing, many stores lack the tools, spaces, or training needed to demonstrate that safety in a credible and accessible way.
The study’s proposed trust reconstruction mechanism can be summarized through the following priorities:
- Make electric vehicle battery status visible through real-time monitoring and intuitive visual displays.
- Convert thermal management claims into physical, interactive experiences that consumers can operate and observe.
- Connect retail demonstrations with verifiable test data so that electric vehicle safety information can be traced and checked.
- Reduce the technical cognition barrier that prevents ordinary buyers from understanding battery protection systems.
- Support sales staff with visualization tools and regular technical training so that electric vehicle safety communication is accurate and consistent.
- Address consumer anxiety through balanced, evidence-based presentations rather than fear-driven or promise-heavy messaging.
3. Retail Survey Findings Show a Safety Communication Gap
The survey results reveal a substantial gap between the importance of electric vehicle battery safety and the retail infrastructure available to explain it. Only 3 of the 30 stores used a battery section model or a thermal runaway animation for safety display, a share of about 10 percent. In addition, 33 percent of the stores did not provide any battery safety promotional materials. More than half of the sales staff relied on safety certification certificates or warranty commitments when responding to consumer questions. These methods may be formally correct, but they do not give consumers a direct sense of how an electric vehicle battery operates, how heat is managed, or how safety systems intervene.
The study also found that none of the interviewed stores had established an experience space dedicated to battery operating status. This is a significant finding for the electric vehicle industry because it suggests that the retail environment remains largely transaction-oriented. A buyer may see vehicle styling, interior features, charging specifications, and financing options, but may have few opportunities to observe the battery system in action or to understand what happens when temperature, voltage, or current moves outside normal ranges. For a product category where battery safety is a central purchase consideration, this absence weakens the ability of electric vehicle brands to convert technical investment into consumer confidence.
At the same time, the survey indicates interest in change. Forty-two percent of the stores planned to build a safety emergency experience room, with functions concentrated on battery safety demonstration and escape simulation training. Sales personnel also expressed demand for better tools. Among the respondents, 42.9 percent said they needed visualization data display tools, while 28.6 percent expected regular technical training. These figures suggest that frontline staff recognize the difficulty of explaining electric vehicle safety with traditional sales materials alone. However, the study also reports that 25 percent of respondents worried that a thermal management experience room might trigger consumer anxiety, indicating that the design and tone of such spaces must be handled carefully.
| Survey dimension | Reported finding |
|---|---|
| Reported electric vehicle fire incidents | 1,730 cumulative reports from 2018 to November 2024 |
| Complaint concentration | 85 percent linked to power battery faults, overstated range and power interruption, and slow charging |
| Retail sample | 30 electric vehicle sales stores in Guangzhou, Foshan, and Dongguan |
| Battery safety display | 3 stores, or about 10 percent, used a battery section model or thermal runaway animation |
| Missing safety materials | 33 percent of stores had no battery safety promotional materials |
| Sales response methods | More than half relied on safety certification certificates or warranty commitments |
| Battery operating status experience space | None of the interviewed stores had established such a space |
| Planned safety experience rooms | 42 percent of stores planned to build a safety emergency experience room |
| Sales tool demand | 42.9 percent needed visualization data display tools; 28.6 percent expected regular technical training |
| Anxiety concern | 25 percent of respondents worried that a thermal management experience room might cause consumer anxiety |
The survey findings are particularly important for the electric vehicle market because they show that consumer trust is not built automatically by technical progress. A safety certificate can document compliance, and a warranty can define responsibility, but neither necessarily helps a buyer understand why an electric vehicle battery is less likely to overheat, how a cooling system responds under load, or how a battery management system behaves during a puncture event. The research argues that the retail environment needs new forms of evidence. For the electric vehicle industry, the challenge is to make safety visible without oversimplifying risk or creating unnecessary alarm.
4. Battery Status Visualization: Making Electric Vehicle Safety Data Perceptible
The first trust reconstruction path proposed by the study is a battery status visualization system. The concept begins at the hardware level. A high-precision sensor network is embedded in the battery module, with each cell equipped with independent temperature, voltage, and current monitoring units. This creates a denser flow of information than a conventional overview would provide. The system is designed to respond automatically according to preset safety thresholds. When local temperature abnormality is detected, the system immediately increases coolant flow in the corresponding area. When voltage fluctuation exceeds the set range, it adjusts positive temperature coefficient heating power to balance cell conditions. These responses are intended to make the electric vehicle battery system more adaptive and more transparent.
The consumer-facing layer is equally important. The study proposes a dynamic visualization interface that displays the temperature distribution of the entire electric vehicle battery pack on the central control screen. The display uses gradient color blocks to form a temperature cloud map. Red indicates high-temperature zones, while blue indicates low-temperature zones. This design transforms invisible electrochemical and thermal conditions into a spatial image that a driver or passenger can understand at a glance. Instead of waiting for a warning light, the user can see where heat is accumulating and how the system is responding. The study argues that this kind of real-time visualization can provide early warning of abnormal heating and create a scenario of technical transparency.
The research also proposes a physical display device called a transparent battery cabin for dealership showrooms. The core area uses a detachable battery pack module, with LED strips embedded inside to simulate current transmission paths in real time. Two linked screens support the display. The left screen continuously refreshes real-time parameters such as charging and discharging voltage and temperature. The right screen uses a slow-motion decomposition animation to demonstrate the mechanical operation principle of the cell expansion suppression structure frame by frame. This combination allows visitors to connect abstract electric vehicle battery data with physical structure and function.
A condition simulation console adds another layer of interaction. The console includes scenarios such as continuous fast charging and cold starting at minus 30 degrees Celsius. When a visitor presses a button, the lighting inside the cabin switches to an orange-red warning effect and triggers a protection mechanism demonstration video for the corresponding scenario. For fast charging, the video may show a fluid animation of coolant flow doubling. For an extreme cold environment, the display may show an infrared thermal imaging sequence of the cell self-heating system. These demonstrations are designed to create an immersive science communication experience that helps consumers understand how an electric vehicle manages thermal risk across different operating conditions.
The significance of this visualization approach is that it turns electric vehicle safety from a set of claims into a set of observable relationships. The user can see that temperature is monitored, that cooling responds, that voltage is balanced, and that protection systems are active. The study does not claim that visualization eliminates risk. Rather, it argues that visualization reduces the cognitive distance between the technical system and the consumer. When an electric vehicle buyer can perceive how the battery behaves, the conversation shifts from abstract fear to specific understanding. This is a crucial step in rebuilding public trust in electric vehicle safety.
5. Immersive Thermal Management Experience: From Passive Claims to Active Verification
The second trust reconstruction path is a thermal management experience space built around an operation, observation, and verification process. The study proposes turning battery safety technology into a tangible interactive environment. In the hardware interaction area, a transparent acrylic thermal runaway experiment bench contains a scale battery model and cooling pipelines. A knob allows users to adjust the power of the liquid cooling pump. As the flow changes, red temperature-sensitive powder diffuses dynamically through the model, making the movement of cooling and heat visible. When the temperature exceeds 60 degrees Celsius, a buzzer alarm is triggered and a pressure relief valve burst demonstration is activated. This sequence gives consumers a direct sense of how an electric vehicle thermal management system responds as conditions move toward extreme limits.
An adjacent collision dissection wall provides a structural view of electric vehicle battery protection. The display shows a buffer layer, a circuit cut-off device, and a leak-proof membrane structure. When a user operates an impact hammer, three-color LEDs light up in sequence, mapping the full protection response from impact absorption to circuit disconnection and electrolyte sealing. This exhibit helps consumers understand that electric vehicle safety is not located in a single component. It is distributed across materials, structural design, electrical control, and sealing systems. By allowing users to trigger the sequence themselves, the experience space transforms passive viewing into active learning.
The VR training area extends the concept into virtual environments. Equipped with force feedback gloves and multi-scenario virtual experiment spaces, the area allows users to conduct simulated tests that would be difficult or unsafe to perform in a showroom. In a puncture experiment, a user controls a probe to puncture a battery model and triggers dynamic thermal imaging. A shallow puncture displays a red spot, while deep penetration immediately activates a smoke alarm and a battery management system interception response. In multi-climate tests, a desert high-temperature scenario simulates the hot touch of the battery shell and the opening of heat dissipation vents. An extreme cold scenario requires the user to manually start the preheating system, with vibration feedback reflecting the operation of the heating plate. These interactions create a strong association between environmental parameters and sensory feedback.
The study emphasizes that the experience space is not designed to create fear. Instead, it is intended to show how electric vehicle safety systems operate under controlled and explainable conditions. This distinction is important because 25 percent of surveyed respondents worried that a thermal management experience room might cause consumer anxiety. The research responds to this concern by proposing a structured, educational presentation. The goal is not to dramatize fire risk but to demonstrate the sequence of protection, the role of monitoring, and the logic of thermal management. When consumers can operate the model and verify the response, they are better able to distinguish between a controlled demonstration and an uncontrolled accident narrative.
6. Data Transparency and the Closed Loop of Trust
The study argues that visualization and experience must be supported by data traceability. Otherwise, interactive exhibits risk becoming entertainment rather than evidence. To address this, the research proposes using NFC technology to connect the offline experience with vehicle test data. A consumer can place a mobile phone near a sensing tag on a display vehicle and immediately obtain that vehicle battery’s factory inspection report, as well as recorded videos of vibration table and salt spray tests. This creates a direct link between the showroom experience and verifiable documentation. The consumer does not need to rely solely on a sales explanation or a brochure. The electric vehicle’s safety story can be traced to recorded test evidence.
This data transparency component completes what the study describes as a full-chain trust reconstruction mechanism. The first layer is dynamic monitoring: sensors track temperature, voltage, and current in real time, and the visualization interface presents battery status in an understandable form. The second layer is scenario verification: physical experiment benches, collision dissection walls, and VR training allow consumers to observe safety responses under specific conditions. The third layer is data transparency: NFC-linked reports and test videos provide a traceable record that supports the claims made in the retail environment. Together, these layers create a closed loop in which electric vehicle safety is monitored, demonstrated, and documented.
The research suggests that this closed loop can systematically reduce consumer technical cognition barriers. Many electric vehicle buyers are not battery engineers. They may not know how a battery management system balances cells, how a cooling plate distributes coolant, or how a pressure relief valve functions. However, they can understand a temperature cloud map, a visible coolant flow demonstration, a sequential LED protection display, and a factory inspection report. By translating technical information into multiple forms of evidence, the study offers a practical way for the electric vehicle industry to rebuild trust without asking consumers to become specialists.
7. Industry Implications for Electric Vehicle Retail and Safety Communication
The study has several implications for electric vehicle manufacturers, dealers, and safety communicators. First, safety communication should move from assertion to demonstration. Electric vehicle brands already invest in battery testing, thermal management, and structural protection. These investments need to be translated into retail experiences that consumers can see, touch, and question. A certificate on a wall is useful, but a working thermal management model can be more persuasive because it shows how the system behaves. For the electric vehicle market, demonstration is not a marketing extra. It is a trust-building necessity.
Second, sales staff need better tools and training. The survey found that 42.9 percent of sales personnel needed visualization data display tools and 28.6 percent expected regular technical training. These figures indicate that frontline staff are often asked to explain complex electric vehicle safety systems without adequate support. If salespeople rely mainly on certificates and warranty commitments, consumers may interpret the response as defensive or incomplete. Regular training can help staff explain battery monitoring, thermal management, and emergency response in clear language. Visualization tools can help them show rather than tell. This is especially important for electric vehicle buyers who are new to battery technology and may have heard conflicting information about fire risk.
Third, experience spaces should be designed with emotional care. The study reports that 25 percent of respondents worried a thermal management experience room might cause consumer anxiety. This concern is reasonable. A demonstration that focuses only on fire, smoke, and failure could reinforce fear rather than reduce it. The research therefore favors a balanced design that explains protection mechanisms, shows controlled responses, and places risk in context. The goal is not to pretend that electric vehicle batteries never fail. The goal is to show how engineering, monitoring, and emergency systems work together to manage risk. This approach respects consumers’ intelligence while avoiding alarmist messaging.
Fourth, data transparency should be integrated into the retail experience. The use of NFC tags to provide factory inspection reports and test videos is a practical example of how electric vehicle brands can make safety information accessible at the point of sale. Consumers increasingly expect evidence. A claim that a battery has passed vibration and salt spray testing is stronger when the buyer can access a recorded test video or a report. This kind of transparency can differentiate a responsible electric vehicle brand in a competitive market. It can also help standardize safety communication across dealerships, reducing the inconsistency that currently exists.
Fifth, the study suggests that fire and rescue experience can inform retail safety communication. The involvement of the Foshan City Shunde District Fire and Rescue Brigade in the research highlights the importance of emergency response knowledge. Consumers may have questions about what to do in the event of a battery fire, how emergency responders approach an electric vehicle incident, and what safety features are designed to do. A well-designed experience space can include escape simulation and emergency response information without turning the showroom into a hazard display. This broader perspective supports public confidence in the electric vehicle ecosystem, not just in a single product.
8. Conclusion: Trust as a Product of Visible Evidence
The electric vehicle industry is entering a phase in which public trust must be actively maintained. Rapid ownership growth has brought battery safety into the center of consumer decision-making, and reported fire incidents have amplified concern. The study reviewed here argues that technical improvement, accident prevention, and insurance mechanisms remain essential, but they are not sufficient on their own. Consumers need a way to understand and verify electric vehicle safety in ordinary retail settings. Without that understanding, even strong technical systems may struggle to overcome public skepticism.
The proposed trust reconstruction mechanism offers a practical response. Battery status visualization uses high-density sensing and dynamic interfaces to make temperature distribution, voltage conditions, and cooling responses visible. The transparent battery cabin and condition simulation console allow consumers to connect data with physical structure. The thermal management experience space uses a liquid-cooling experimental bench, a collision dissection wall, and VR training to let users observe protection sequences under controlled conditions. NFC-linked test reports and videos add a layer of data transparency. Together, these elements create a full-chain approach that moves from dynamic monitoring to scenario verification and data traceability.
For the electric vehicle market, the broader lesson is that trust is not produced by repetition alone. It is produced when claims can be seen, tested, and traced. The study’s consumer-centered approach does not dismiss engineering or regulation. Instead, it asks the electric vehicle industry to communicate safety in a way that matches the sophistication of the technology itself. When buyers can perceive how an electric vehicle battery is monitored, how thermal risk is managed, and how safety data is documented, public confidence has a stronger foundation. That foundation is essential for the next stage of electric vehicle adoption, in which safety is not only a technical specification but also a visible and verifiable public commitment.
