What Technologies Are Needed for New Energy Vehicle Maintenance?
2 Answers
New energy vehicle maintenance mainly involves three technologies: battery maintenance, drive system controller maintenance, and startup fault maintenance. Battery maintenance technology: First, clearly recognize the important value of battery protection board specifications; second, regularly perform charging and discharging on the battery; third, conduct regular fault inspections to promptly identify and eliminate potential causes of battery failures; finally, ensure the vehicle is turned off and power is disconnected during battery maintenance. Drive system controller maintenance: First, when performing fault detection and maintenance on the drive system controller of a new energy vehicle, power must be disconnected in advance; second, during controller inspection, regular fault checks and troubleshooting must be conducted; third, during controller maintenance, technicians should avoid touching the surface operation buttons and handle dust accumulation properly. Startup fault maintenance: First, technicians can inspect the vehicle's condition to determine the fault location or use advanced instruments for measurement checks; second, after identifying the fault location, technicians need to investigate the cause of the fault to develop more targeted fault elimination measures, improving maintenance efficiency and precision.
I've repaired quite a few new energy vehicles, and I believe the most crucial aspect is high-voltage electrical technology. These cars operate at very high voltages, often reaching several hundred volts. During maintenance, it's essential to first cut off the power and use specialized testing tools to inspect the battery and motor. You also need to understand electronic control systems, such as the battery management system, which monitors battery temperature to prevent overheating and potential hazards. Additionally, software diagnostics are vital, as many fault codes need to be read via a computer, like Tesla vehicles that often require firmware updates. In reality, repairing new energy vehicles differs from traditional cars—there's no engine, but you have to deal with charging systems and motor maintenance, requiring more specialized training and accumulated experience. I think it takes at least two to three years to go from beginner to expert, and I recommend taking certified courses and gaining hands-on experience to handle various situations. In short, with rapid technological advancements, continuous learning is a must—don't assume new energy vehicles are easy to repair.
