What does 'EV function restricted' mean?
2 Answers
EV function restricted usually means the high-voltage system of the car is damaged. Here are the relevant details: 1. Handling EV function restriction: When the car shows EV function restriction, it should be taken to a repair shop or 4S store immediately for professional repair to avoid unnecessary trouble during use. 2. Detailed introduction of EV: EV is the English abbreviation for electric vehicles. The full name of EV on hybrid vehicles is HEV, which stands for hybrid electric vehicle. Hybrid power means the car uses both gasoline and electric power for driving. The advantage is that when the vehicle starts and stops, it is only driven by the generator. The engine does not work until a certain speed is reached. Therefore, the engine can always be kept in the best working condition, with good power performance and very low emissions, and the source of electric energy is the engine.
When my electric vehicle displays the 'EV function restricted' warning, it typically indicates that the vehicle has automatically limited power output, likely to protect core components. Common causes include battery overheating, charging system malfunctions, software errors, or sensor signal interruptions. For example, driving in high summer temperatures can cause battery temperatures to spike, prompting the control unit to reduce power to prevent damage; or voltage instability may trigger the protection mechanism, affecting acceleration and speed. In daily use, I recommend first finding a safe place to park and attempting to restart the system—hold the start button for 10 seconds. If the warning light remains on, avoid forcing the vehicle to operate and visit an authorized service center as soon as possible for a comprehensive inspection, as this involves the high-voltage electrical system. Neglecting it could lead to more expensive repairs. Regular maintenance and timely software updates can help prevent similar issues. I've also noticed that many owners trigger these restrictions after modifying circuits or installing aftermarket devices, so it's best to avoid tampering with factory settings unnecessarily—ensuring driving safety should always come first.
