At the 48th WorldSkills Competition in China, the automotive technology contest now includes a dedicated new-energy vehicle (NEV) repair module that has been expanded to four hours, up from just 30 minutes two editions ago. The change mirrors a broader shift in the auto repair industry, where technicians must now master not only mechanical basics but also high-voltage electrical systems, battery management, and software diagnostics.
From 30 Minutes to 4 Hours: The New Skillset
According to the WorldSkills organization's latest occupational standard for automotive technology, electrical and mechanical system inspection and diagnosis account for 45% of the scoring, with repair and overhaul at 20%. Competitors must perform vehicle checks, fault diagnosis, and repairs using diagnostic equipment to read data and identify root causes. The new-energy powertrain content has grown from 0.5 hours at the 46th WorldSkills to 2 hours at the 47th, and now 4 hours at the 48th, covering battery management systems, electronic control units, and high-voltage systems.
The shift is driven by the rapid adoption of NEVs in China. Public security data shows that as of June 2026, there were 48.97 million NEVs on Chinese roads, accounting for 13.19% of all vehicles. The China Association of Automobile Manufacturers' aftermarket branch estimates the NEV maintenance and repair market will reach about 90.4 billion yuan (roughly $12.7 billion) in 2025 and exceed 100 billion yuan (about $14.1 billion) in 2026.
However, the supply of qualified technicians lags far behind demand. The China Automobile Maintenance Industry Association estimates a talent shortage of about 824,000 in the NEV after-sales service sector. Only 2% to 3% of repair shops are capable of servicing 'three-electric' systems (battery, motor, and electronic control), and only about a quarter of repair personnel can handle battery testing and repair work.
High Voltage, High Stakes
Repairing NEVs is fundamentally different from working on traditional combustion-engine cars. High-voltage systems can operate at up to 800 volts, requiring technicians to follow strict safety protocols—de-energizing, verifying zero voltage, and using insulated tools—and to hold an electrician's certificate. Fault diagnosis relies less on listening for odd noises or inspecting parts visually and more on reading diagnostic trouble codes, analyzing data streams, and interpreting battery management system logic.
"Diagnosing three-electric systems often means reading data, looking at code, and analyzing the working logic of the battery management system," one engineer told Interface News, which is carried by Huxiu. The complexity is compounded by over-the-air software updates, which mean technicians must continually learn to keep up with evolving vehicle intelligence.
Vocational schools are responding by overhauling curricula. A teacher at a vocational college involved in NEV repair courses told Interface News that programs are shifting from traditional engine and transmission teardown to high-voltage safety, battery management, electronic control diagnostics, and intelligent diagnostic tools. Schools are combining virtual simulation with hands-on training on real vehicles, though high-voltage training equipment costs several times more than traditional tools.
The industry is also extending training beyond school. Tuhu, a major auto service chain, has partnered with over 100 vocational schools since 2018, training more than 4,000 NEV repair technicians, with nearly 1,500 earning low-voltage electrical work certificates. The company plans to build a tiered service network—from basic maintenance to three-electric repairs and battery reconditioning—extending into third- and fourth-tier cities and county markets.
Salaries reflect the premium on new skills. Traditional repair technicians earn 5,000 to 8,000 yuan per month (about $700 to $1,130), while those with NEV repair skills can earn 15,000 yuan (about $2,110) or more, with some companies offering double pay to attract talent. As a teacher noted, "The next three to five years will see a peak in maintenance for both traditional and new-energy vehicles as warranties expire, and those entering the field now will have a key window of opportunity."
