CINEVE | Under Technological Upgrades, New Energy Vehicle Maintenance Must Uphold Safety and Professional Standards

The 2026 Beijing Auto Show is in full swing, featuring technology-intensive showcases such as BYD's solid-state batteries and CATL's ultra-fast charging batteries. These innovations are driving multidimensional upgrades in new energy vehicles, including range, charging efficiency, and safety. At the same time, issues like battery fires and sudden range drops remind us that professional maintenance is key to ensuring vehicle safety. Especially during periods of rapid technological iteration, maintenance standards must keep pace.

The core of new energy vehicle maintenance lies in the “three-electric” system, and recent technological trends have slightly shifted maintenance priorities. With the widespread adoption of BYD’s second-generation Blade Battery and CATL’s Shenxing ultra-fast charging battery, safety requirements for high-voltage system maintenance have become stricter. Before any service, technicians must strictly follow the “three-step power-off” procedure: turn off the high-voltage switch, disconnect the low-voltage battery negative terminal, and let the system sit for at least 10 minutes to discharge residual electricity. During operation, insulated equipment rated over 1000V must be worn to completely eliminate the risk of electric shock.

Battery maintenance has become the top priority in vehicle servicing. Recent EV fire incidents in Nanping, Fujian, highlight that thermal runaway in batteries often stems from neglected routine care. During maintenance, battery health (SOH) must be carefully checked—if capacity drops more than 5% within a year, timely repair is required. Technicians should also inspect the battery pack for scratches or leaks to prevent hidden structural risks. For ultra-fast charging batteries, charging ports must be checked for overheating or poor contact to avoid safety incidents caused by charging failures.

The rise of intelligent systems also brings new challenges to maintenance. At the Beijing Auto Show, technologies like Huawei QianKun ADS 5 and Xpeng VLA autonomous driving systems demonstrate that servicing electronic control systems now relies heavily on specialized equipment. Technicians must use dedicated diagnostic tools to read fault codes and analyze data streams to assess the operation of autonomous and electronic control units, preventing malfunctions caused by improper checks. Routine maintenance and emergency response remain equally important. Vehicle owners should regularly check tire pressure, air-conditioning filters, and other wear-prone parts, and inspect electrical connectors after water exposure. If warning signs appear—such as battery overheating or a sudden range drop exceeding 15%—use must be stopped immediately and professional inspection sought. In the event of a battery fire, do not attempt manual rescue or douse with water. Evacuate to a safe area and call 119, clearly stating the vehicle type.

In addition, choosing the right maintenance channels is critical. With rapid technological updates, third-party repair shops must verify their qualifications and prioritize brand-authorized service centers, ensuring technicians hold high-voltage electrician certifications to avoid safety risks from improper operations. Meanwhile, the 2026 auto insurance regulations now cover spontaneous fires from non-human causes under vehicle damage insurance, so keeping maintenance records can better protect owners’ rights. As new energy vehicle technologies evolve rapidly, the maintenance industry must keep pace, upholding safety and professional standards. For owners, understanding basic maintenance knowledge and prioritizing regular inspections ensures that new technologies truly enhance mobility—offering convenience and efficiency while safeguarding their own and others’ safety.

Breaking News: Spotlight on New Energy Vehicle Maintenance to Drive Industry Innovation

The China International New Energy Vehicle Technology, Components & Services Exhibition is set to tackle the most pressing challenges in EV repair. From in-depth disassembly at live teardown sessions to peak-level skills competitions, we stay true to our mission: “address pain points, solve problems, and empower the industry.” This year, with the theme of “The Hardest-to-Repair New Energy Vehicles,” we will focus on key pain points for both B2B and B2C markets. The event will connect EV maintenance training institutions across China, as well as overseas partners in the Philippines, Finland, Brazil, and beyond. By integrating maintenance parts, professional tools, and technical expertise, we aim to link repair shops, training centers, and component and tool manufacturers. The exhibition will build a one-stop ecosystem combining training, tools, parts, and real-world scenarios, addressing critical industry challenges such as difficult repairs, high costs, lack of spare parts, and shortage of skilled technicians. This holistic approach supports long-term industry health and elevates the EV maintenance ecosystem.
