What to do if the Chery Ant shows high-voltage system cut off and cannot start?

Insufficient battery power can cause the car to fail to start. You can choose to ask for help from nearby car owners, applying for emergency measures such as jump-starting, borrowing fuel, or towing. If the steering wheel is locked and causes the car to fail to start, the solution is to shake the steering wheel while turning the key. P or N gear is the correct gear for starting an automatic car. Adjust to the correct gear and try to start the car again.
I once encountered a high-voltage system cut-off warning in my Chery Ant that prevented the car from starting. Don't panic and act rashly. First, park the car safely by the roadside and make sure no one approaches the high-voltage area. Try turning off all power, wait 5-10 minutes, then restart - sometimes the system just needs a reset after false alarms. Check if the charging port is properly connected, and don't leave the charging gun plugged in when not charging to avoid false triggers. If it still doesn't work, it might be due to battery overheating or insulation failure - never attempt DIY fixes as high-voltage components are dangerous. My last breakdown was caused by unstable voltage in the low-voltage battery triggering the high-voltage protection system. I ended up calling professional towing to the 4S shop where technicians used diagnostic tools to identify relay contact issues, fixed in half an hour. Remember: high-voltage system safety comes first - leave it to professionals. Avoid prolonged parking in extreme heat or rain to prevent such failures, saving both hassle and money.
After years of playing with electric vehicles, I've summarized that the high-voltage system cutoff in the Little Ant is often caused by minor electrical issues. The high-voltage drive section includes the battery pack and control module, which will cut off for protection when sensors detect overvoltage, undervoltage, or abnormal temperatures. Try disconnecting the negative terminal of the 12V auxiliary battery for two to three minutes and then reconnecting it to reset the ECU system—sometimes communication errors or false alarms will disappear. Don't attempt to inspect high-voltage wiring yourself due to the high risks involved; instead, use an OBD scanner to read fault codes and identify issues like loose connections or blown fuses. Prevention is simple: avoid deep discharge and charging, maintain battery health between 20% and 80%, and perform regular maintenance checks on wiring connections. My car once had a false alarm due to sensor dust, which was resolved after cleaning. High-voltage system maintenance is a specialized field—if you're unsure, consult an expert for safety and efficiency.
