How to Solve the Issue of BYD Qin Failing to Switch to Pure Electric Mode?
4 Answers
Restarting the vehicle and starting in pure electric mode can resolve the issue. If the main screen displays insufficient voltage, please visit a 4S dealership to check whether the problem lies with the system or hardware. Below is relevant information: 1. Interior: The Qin 100 features significant changes in its interior, including a large LCD touchscreen on the center console. Additionally, the vehicle comes with a new steering wheel, instrument panel, and other components, with visible leather accents and stitching design throughout. 2. Powertrain: In terms of powertrain, the BYD Qin 100 is expected to continue using a plug-in hybrid system consisting of a 1.5TI engine and an electric motor. The transmission system is paired with a 6-speed DCT gearbox, and the gear lever also adopts a new design.
I also encountered the issue of not being able to switch to pure electric mode when I last drove the BYD Qin, and it took me quite a while to resolve it. Most likely, the battery level was too low and automatically locked. First, check the remaining battery level displayed on the dashboard—when it's below 20%, the system restricts switching. If it still doesn't work after fully charging, try turning the car off and restarting it a few times; sometimes the software glitches and requires a hard reset. In cold weather, low battery temperature can also cause it to get stuck, so try again after warming up the vehicle. Also, don’t overlook the settings menu—confirm that the EV mode is enabled. Some versions require enabling the option in the central control screen. If none of these work, it might be a relay or control module failure. It’s recommended to visit a 4S shop to scan for error codes with professional equipment. Fixing it early avoids affecting daily driving and can save some fuel costs.
As a frequent hybrid vehicle user, I think the Qin couldn't switch to pure electric mode—first, don't panic. The most common reason is that the speed is too fast or the driving environment is unstable, causing the system to intervene automatically. Try slowing down to below 50 km/h before pressing the switch button. If there's a warning light on the dashboard, check the manual—it might be a blown fuse. Open the front compartment fuse box, find the corresponding one, and replace it with a spare. In my case, the battery temperature was too high and got stuck, but it was resolved by remotely preheating via the mobile app. Regular maintenance, such as keeping the battery charged, can prevent this. Avoid randomly changing the pure electric priority setting in hybrid mode, and perform regular software updates to prevent bugs. Don't tamper with the circuits yourself—experienced owners might use an OBD tool for diagnosis, but a thorough check at the service center is the most reliable and hassle-free option.
Safety is paramount. If you find that your Qin cannot switch to pure electric mode while driving, do not force the operation. Immediately pull over to check if you are operating in P gear, and try turning off and restarting the vehicle to rule out software issues. When the battery is low or there is a system conflict, the mode may be forcibly locked. Do not assume the button is broken and start tapping it. If the issue persists, it could be due to sensor failure or risk of circuit overheating. Contact a BYD service center immediately for a multimeter test. Hybrid vehicles have complex circuits, and self-repair is not recommended. Leave it to the technicians for the safest solution to avoid unexpected stops while driving that could affect others. Developing a habit of preheating can help prevent similar issues.
