What are the precautions for new energy vehicle maintenance?
2 Answers
Precautions for new energy vehicle maintenance include turning off the high-voltage switch before maintenance. During the operation, if the maintenance involves the power system, the power supply must be disconnected. Operators must wear insulated gloves and shoes, and use insulated tools according to the specified procedures and processes. During the vehicle maintenance process, the safety operation regulations for electrical circuits must be strictly followed. Precautions for using new energy vehicles: 1. Avoid high-current discharge. 2. Do not store the vehicle with a depleted battery. 3. Master the correct charging time. 4. Regularly check tire pressure. 5. Avoid exposure to direct sunlight. 6. Perform regular inspections.
When repairing new energy vehicles, the top priority is high-voltage safety. Unlike traditional cars, the high-voltage battery packs in new energy vehicles can reach hundreds of volts—getting shocked is no joke. Before starting any repairs, professionals must cut off the high-voltage power supply and ensure that insulation protection is in place. The repair area should be well-ventilated to avoid hazards from battery chemical leaks. Specialized tools are also required, as ordinary wrenches can easily cause short circuits and fires. When handling battery packs, they must be moved gently to prevent lithium cells from overheating or catching fire due to impact. After completing the work, a megohmmeter must be used to test insulation resistance, ensuring there is no leakage before handing over the vehicle.
