How to Resolve Changan New Energy Power Failure?

With proper insulation protection, open the vehicle doors; Check if the vehicle's gear is in the OFF position; Disconnect the front compartment 12V battery; Disconnect the maintenance switch (canceled in Tang models); Inspect the power battery tray edges for cracks or any noticeable fluid leakage.

I've encountered the Changan New Energy power failure issue several times. The key is to check a few aspects while ensuring safety first. The battery is a major concern—if the charge display is low or it won't charge fully, the battery pack might be damaged and need replacement. Also, poor contact in high-voltage wiring can cause power interruption. My friend's car once lost all power due to water ingress in the connectors during rain, leading to a short circuit. It's best to find a safe spot, park, and check the dashboard for any flashing fault codes. If system error codes like P0 appear, it usually indicates a battery management system issue requiring a software update. For prevention, regular battery maintenance and minimizing fast charging can slow down aging. If a fault occurs, stay calm, drive slowly to the roadside with hazard lights on to avoid serious accidents. For repairs, always visit a 4S shop or professional technicians—since new energy vehicles have high voltage, DIY fixes are extremely dangerous.

The most common power failure I've encountered with Changan's new energy vehicles is issues with the motor drive system. After driving this car for a long time, I've noticed that if the motor makes a buzzing noise during operation or experiences intermittent power loss, it's usually due to insufficient cooling caused by clogged heat sinks that need cleaning. Another frequent issue is loose connections in the transmission system leading to power interruption. Once when I was on a long trip, the power suddenly dropped, and upon inspection, it turned out the motor control unit had water damage and corrosion, requiring replacement of the entire module. I recommend regularly monitoring charging status - if the charger smokes or overheats significantly, it's an overheating warning. Users with technical skills can learn basic diagnostics like using a multimeter to measure voltage, but should never disassemble high-voltage components. Repair shops typically recalibrate system parameters to ensure proper matching. For prevention, conduct a comprehensive inspection quarterly - don't neglect these small issues as they can accumulate into major problems.
