What is the EV limitation of Qin Plus DM-i?
3 Answers
Cause analysis: 1. Battery pack failure 2. High-voltage electrical appliance failure 3. Line and other failures. EV function limitation generally means the high-voltage system of the car is damaged. When the car shows EV function limitation, it is necessary to promptly take it to a repair shop or 4S store for professional repair to avoid unnecessary trouble during use. About EV: EV stands for electric vehicle, which is the abbreviation for electric cars. As of 2019, pure electric vehicle brands sold in China include Tesla, BAIC EV series, etc. Pure electric vehicles have both advantages and disadvantages. Their biggest advantage is environmental friendliness, as they produce almost no tailpipe emissions, thus causing no pollution to the environment. Pure electric vehicles also produce less noise during operation, making the ride more comfortable. The disadvantages of pure electric vehicles are also quite obvious, as their range is certainly not as good as that of fuel vehicles. In remote areas, charging may not be very convenient. In terms of popularity, pure electric vehicles still have a long way to go.
I'm quite familiar with the EV restriction issue in Qin Plus DM-i. Having driven a hybrid for two years, I've encountered it several times. Simply put, the car won't allow electric mode operation, and the system pops up an alert saying EV function is restricted. Common causes include low or aging battery charge, control software bugs, or temperature conditions affecting normal operation. Once in winter, my battery was too cold and triggered the restriction, forcing me to switch to fuel mode. It's crucial to get it checked at the dealership promptly - sometimes just a free software update or minor part replacement is needed. Regular battery maintenance and avoiding deep discharge can prevent such issues. While not catastrophic, it's annoying, especially during long trips when power reduction slows you down. I recommend owners develop habits of regular charging and system updates rather than waiting for problems. Essentially, it's the vehicle's self-protection mechanism temporarily disabling EV mode until resolved.
As an experienced driver, EV limitation is common in hybrid vehicles, referring to the electric part not functioning properly. I often encounter power shortage leading to limitations, feeling the car's acceleration is weak and fuel consumption increases. Possible reasons include unstable battery voltage, control module failure, or poor wiring contact. The solution is simple: first, stop and check the battery status or try charging it a bit; if that doesn't work, go to a repair shop for troubleshooting. Once, I was limited halfway on a business trip and managed to drive by refueling, then got it fixed at a small cost. For prevention, maintain good charging habits to avoid power depletion and regularly check for software updates. Although it doesn't affect basic driving, it may impact comfort, so address it promptly without ignoring it. Regular maintenance can extend battery life and reduce failures. Remember, safety first—don't force EV mode to avoid other issues.
