What causes the battery warning light to illuminate in the Chery EQ?
2 Answers
The reasons for the battery warning light to illuminate are: 1. Oxidation on the battery connection cables; 2. Loose battery terminal connections; 3. Battery damage; 4. Loose or slipping generator belt; 5. Insufficient power generation from the alternator; 6. Damaged alternator rectifier bridge, resulting in uncontrolled output voltage; 7. Broken alternator belt, damaged alternator, or broken positive/negative cables. Additional relevant information is as follows: 1. Introduction: A battery generally refers to any chemical energy storage device that can be recharged and reused after its charge is depleted to a certain extent. 2. Principle: Also known as a rechargeable battery, it can be recharged because its chemical reaction can be reversed when connected to an external power source.
As an owner of the Chery EQ, I've encountered the battery fault light coming on multiple times, which can stem from various causes. Insufficient battery charge is the most common trigger, especially when the EV isn't fully charged. Additionally, issues with the charging system—like a loose charging port or faulty charger—can hinder energy intake and illuminate the warning. A malfunctioning BMS (Battery Management System) or inaccurate sensor readings may also cause false alarms. Hardware problems such as damaged high-voltage batteries or corroded wiring demand immediate attention, while software glitches often require system reboots or updates. From my experience, when the light appears, the vehicle may struggle to start; it's crucial to pull over and check the charge level to avoid roadside breakdowns. I strongly recommend visiting a service center promptly for professional diagnosis using OBD scanners—DIY fixes are risky with high-voltage systems. Regular battery health checks and proper charging habits can significantly reduce such occurrences.
