What are the reasons for the BAIC New Energy EU5 failing to start?
4 Answers
BAIC New Energy EU5 may fail to start due to ignition system failure or battery issues. Below is an introduction to the BAIC New Energy EU5: 1. Vehicle Positioning: The BAIC New Energy EU5 is positioned as a compact pure electric sedan, launched during the Beijing Auto Show. 2. Body Dimensions: The BAIC New Energy EU5 has body dimensions of 4650/1820/1510mm (length/width/height) with a wheelbase of 2670mm. 3. Vehicle Advantages: The BAIC New Energy EU5 features a smart brain that comprehensively monitors data from 250 vehicle components, intelligently analyzes and makes decisions, allocates power smartly, and adjusts power output, optimizing battery performance and lifespan, enhancing motor power and transmission efficiency, resulting in superior overall performance and extended range.
I've worked on quite a few BAIC EU5 electric vehicles, and most no-start conditions stem from the power system. First, you need to check if the 12V auxiliary battery is dead - the startup control system of new energy vehicles relies entirely on this small battery. If it's depleted, the dashboard might not even light up, or display various warning lights. In this case, use a multimeter to measure the voltage - if it's below 12V, that's likely the issue. Also, don't forget to check if the charging cable has been completely unplugged - once a customer had a stuck charging port causing the system to falsely detect a charging state. Depleted high-voltage battery is another common cause, as charge levels below 5% may trigger protective lockout. Minor issues like unreleased electronic parking brake or faulty gear position sensors can also cause startup failure - it's best to connect a diagnostic scanner to check specific trouble codes.
When driving new energy vehicles frequently, troubleshooting the EU5's failure to start should begin with basic checks. If there's no response when pressing the start button, first check if the smart key has sufficient battery by placing it against the one-touch start button for inductive activation. Then ensure the brake pedal is fully depressed, as the EU5's system won't wake up without the brake pedal sensor being triggered. Pay attention to charging status too - if the circuit tripped during charging last night, the high-voltage battery might not have charged at all. I've also encountered cases where the CAN bus lines got damp and short-circuited, especially after rainy weather or car washes. Additionally, monitor the infotainment screen - if it shows a red drive system failure warning, it's likely an issue with the motor controller. If you can't resolve it yourself, contact after-sales service for roadside assistance immediately.
My neighbor's EU5 just experienced a starting issue a couple of days ago. The main problem was a loose connection on the 12V auxiliary battery terminal, which was resolved by simply tightening it. The 12V battery in new energy vehicles is particularly crucial but often overlooked. Also, check if the charging port cover is properly closed - the EU5's design prevents starting when the charging cover isn't securely shut. A stuck charging gun can cause the same issue; you'll need to give it a firm push to release it. Remember not to leave important documents in the car during daily use, as the anti-theft system will put the entire vehicle into sleep mode when activated. Here's a handy tip: holding the start button for ten seconds forces a system reboot, which can solve occasional software freezes. These simple checks can save both time and towing fees.
