In recent years, the rapid expansion of the electric car industry, particularly in China EV markets, has led to a significant surge in demand for skilled maintenance technicians. As an educator and researcher in the field of vocational training, I have observed that the electric car sector faces critical challenges, including a high gap in skilled labor, fast-paced technological advancements, and a mismatch between training programs and industry needs. This study aims to address these issues by developing a competency model for electric car maintenance technicians based on empirical data from enterprise requirements. By analyzing job postings, conducting surveys, and interviewing experts, I have constructed a comprehensive framework that encompasses key dimensions essential for success in this evolving field. The findings not only provide a foundation for standardizing talent cultivation but also offer insights for reducing operational costs and enhancing competitiveness in the China EV maintenance sector.
The concept of competency modeling traces back to the seminal work of psychologists who introduced the “iceberg model,” distinguishing between visible and hidden traits. Over time, this has been widely applied in various industries to improve workforce efficiency. In the context of electric car maintenance, competency models help bridge the gap between educational institutions and enterprises, ensuring that graduates possess the necessary skills to thrive in the dynamic China EV environment. This research builds on such foundations to create a tailored model that reflects the unique demands of maintaining electric cars, which involve complex systems like high-voltage batteries and advanced electronics.
To gather data for this study, I employed a multi-faceted approach. First, I analyzed job recruitment postings from online platforms and campus recruitment events, extracting key competency indicators related to electric car maintenance. This involved reviewing descriptions of duties, qualifications, and skill requirements. For instance, common themes included expertise in three-electric systems (battery, motor, and electronic control), safety protocols, and the ability to work independently. A summary of these extracted indicators is presented in Table 1, which highlights the frequency and importance of various competencies in the China EV job market.
| Source | Key Requirements | Extracted Competency Indicators |
|---|---|---|
| Online Job Portals | Perform repairs on electric car three-electric systems; require basic electrician certification; emphasis on teamwork and communication. | Three-electric repair skills; responsibility; independence; communication; teamwork. |
| Campus Recruitment | Preference for graduates in electric car maintenance; ability to use tools; follow safety procedures. | Tool proficiency; safety awareness; obedience; feedback skills. |
| Industry Listings | Focus on learning ability and diligence; familiarity with China EV standards. | Learning capability; hard work; diligence; adaptability. |
Next, I distributed electronic questionnaires using a Likert five-point scale to professionals in collaborating enterprises, including human resources managers, workshop supervisors, and team leaders. A total of 25 questionnaires were sent out, all of which were returned. The survey assessed the importance of various competencies from perspectives such as work quality, efficiency, and career progression. Indicators with average scores of 4 or higher were selected, resulting in 23 key traits. These were categorized into broader dimensions, emphasizing the critical role of competencies like information gathering, communication, and service orientation in the electric car maintenance field. The data can be summarized using a weighted formula to calculate the overall competency score: $$ Competency\_Score = \sum_{i=1}^{n} w_i \cdot s_i $$ where \( w_i \) represents the weight of each indicator based on survey importance, and \( s_i \) denotes the score assigned to it. This approach ensures that the model accurately reflects the priorities in China EV maintenance scenarios.
Additionally, I conducted semi-structured interviews with 10 high-performing electric car maintenance technicians to gain deeper insights. The interviews covered topics such as job responsibilities, qualities of potential employees, and factors influencing performance. Through thematic analysis, I extracted additional competency indicators, including observation skills, problem-solving autonomy, and a passion for the trade. These qualitative findings enriched the model by highlighting implicit traits that are crucial for long-term success in maintaining electric cars. For example, the ability to diagnose faults independently was frequently mentioned as a key differentiator in handling complex China EV systems.

Based on the data collected, I constructed a competency model for electric car maintenance technicians, structured into four dimensions: professional skills, general abilities, occupational attributes, and learning capability. This model comprises 27 indicators, aligning with the iceberg model’s division of explicit and implicit traits. Professional skills represent the visible, technical competencies required for electric car maintenance, such as expertise in high-voltage system safety and tool usage. In contrast, general abilities and occupational attributes encompass hidden traits like teamwork, responsibility, and adaptability, which are vital for navigating the fast-paced China EV industry. Learning capability emphasizes continuous improvement, a necessity given the rapid technological evolution in electric cars.
To illustrate the relationships between these dimensions, I propose a mathematical representation: $$ Overall\_Competency = \alpha \cdot PS + \beta \cdot GA + \gamma \cdot OA + \delta \cdot LC $$ where \( PS \) denotes professional skills, \( GA \) general abilities, \( OA \) occupational attributes, and \( LC \) learning capability. The coefficients \( \alpha, \beta, \gamma, \delta \) are derived from survey weights, reflecting their relative importance in the electric car maintenance context. For instance, in China EV settings, \( \alpha \) might be higher due to the technical complexity of electric cars. A detailed breakdown of the indicators within each dimension is provided in Table 2, which serves as a practical guide for educators and employers.
| Dimension | Type | Indicators |
|---|---|---|
| Professional Skills | Explicit | Knowledge of electric car maintenance; high-voltage system safety operation; proficiency with tools; routine vehicle upkeep; high-voltage system maintenance; fault diagnosis and exclusion. |
| General Abilities | Implicit | Information acquisition; communication; teamwork; observation; execution; efficiency; proactivity; obedience; diligence; meticulousness; integrity; comprehension; dedication. |
| Occupational Attributes | Implicit | Responsibility; safety awareness; standardization; endurance; physical fitness; service orientation. |
| Learning Capability | Implicit | Independent problem-solving; summarization ability. |
The implications of this competency model are far-reaching for vocational education and the electric car industry. In educational settings, such as technical colleges, the model can inform curriculum development by integrating these four dimensions into training programs. For example, courses on electric car maintenance should not only cover technical skills but also foster general abilities like communication and occupational attributes such as safety consciousness. This holistic approach ensures that graduates are well-prepared for the demands of the China EV market, where technicians must handle both routine checks and emergent issues in electric cars. Moreover, instructors should transition from traditional teaching methods to facilitative roles, guiding students to develop these competencies through hands-on projects and real-world simulations.
From an enterprise perspective, adopting this competency model can optimize human resource management. By using it in recruitment and training, companies can identify candidates with the right blend of skills and attributes, reducing turnover and enhancing productivity. For instance, in the China EV sector, where electric car technologies evolve rapidly, emphasizing learning capability in hiring decisions can lead to a more adaptable workforce. The model also supports performance evaluations, where competency scores can be tracked over time using the formula: $$ Performance\_Growth = \int_{t_0}^{t_1} Competency\_Score(t) dt $$ This integral approach highlights continuous development, aligning with the lifelong learning required in maintaining electric cars.
In conclusion, this research establishes a robust competency model for electric car maintenance technicians, derived from comprehensive enterprise data. The model’s four dimensions—professional skills, general abilities, occupational attributes, and learning capability—provide a framework for aligning education with industry needs, particularly in the booming China EV landscape. By implementing this model, vocational institutions can produce graduates who are not only technically proficient but also equipped with the soft skills and attitudes necessary for success. Ultimately, this contributes to a more efficient and competitive electric car maintenance ecosystem, driving innovation and sustainability in the global shift toward electric vehicles. Future work could explore the application of this model in other regions or its adaptation to emerging technologies in the electric car domain.
