What are the reasons for restricted EV functionality?
2 Answers
Restricted EV functionality is generally caused by damage to the vehicle's high-voltage system. Here is more information: 1. Handling restricted EV functionality. When the vehicle experiences restricted EV functionality, it is important to promptly take it to a repair shop or 4S store for professional maintenance to avoid unnecessary issues during use. 2. Detailed introduction to EV. EV is the English abbreviation for electric vehicles. On hybrid vehicles, EV stands for HEV, which means hybrid electric vehicle. Hybrid power refers to the vehicle using both gasoline and electric drive systems. The advantage is that when the vehicle starts and stops, it relies solely on the generator. The engine does not work until a certain speed is reached, thus keeping the engine in the optimal working condition, providing good power performance and very low emissions. Additionally, the source of the electrical energy is the engine.
I've been driving electric vehicles for several years and often encounter power limitation issues, mainly due to several common reasons. The most frequent is when the battery charge is too low, and the system automatically restricts speed and power to prevent deep discharge that could damage battery lifespan. Another common cause is minor software glitches, such as failed system updates or temporary crashes, which can usually be resolved by restarting the vehicle. Temperature also plays a significant role - in summer, excessive heat can cause battery overheating and trigger protection limits, while in winter, cold temperatures reduce electrochemical activity and limit performance. Occasionally, faulty sensors may report false issues, or charger malfunctions can cause limitations during charging. It's recommended to regularly check battery health status, avoid completely draining the battery, and charge in moderate environmental conditions when possible. If power limitations occur frequently, it's best to visit a professional shop for diagnosis and troubleshooting, rather than waiting until it affects driving safety.
