What are the solutions for charging trip in new energy vehicles?

The solutions for charging trip in new energy vehicles include: 1. Check whether the external 220V AC power supply is normal. If there is no 220V power supply, replace the charging pile or check the charging socket; if the power supply is normal, proceed to the next step. 2. Check whether the charging cable is damaged. You can confirm this by replacing it with a new cable. 3. Check whether the voltage of the vehicle's 12V battery is normal. If the battery voltage is too low, replace the 12V battery and recharge it for verification. If the same fault persists after replacement, proceed to the next step. 4. Check whether there is 220V high-voltage DC power at the input end of the onboard charger (it can be measured with a multimeter. During the measurement process, wear insulated gloves and wrap the surface of the multimeter with insulating tape, exposing only the head to prevent sparks caused by the positive and negative probes touching each other during the measurement). If there is no input, check whether there is a short circuit in the wire between the vehicle charging port and the onboard charger; if there is high-voltage input, proceed to the next step. 5. If both the 12V power and high-voltage input are normal, it can basically be determined that the onboard charger is faulty, and the onboard charger should be replaced.
Last time I was charging my new energy vehicle at home, the circuit tripped because the regular socket couldn't handle the power demand and there were too many appliances overloading it. The solution is simple: install a dedicated charging line with current matching the vehicle's requirements. Avoid using power strips to connect multiple high-power devices, and turn off appliances like washing machines before charging. It could also be due to a short circuit or loose connections—after cutting power, use a multimeter to check insulation resistance, or gently shake the charging gun to see if the connection is stable. If tripping happens frequently, call an electrician immediately to upgrade your home circuit—don't push it. After installing a dedicated charging station at my home, I haven't had any issues for two years—a small investment for big peace of mind. Prevention tips: regularly clean dust from the charging port, ensure proper grounding, and add anti-leakage protection kits during the rainy season.
After playing with cars for a long time, you gain some technical knowledge. Charging trips often stem from unstable current or poor grounding. The solution starts with checking the charging pile settings and trying to reduce the output current; upgrade the software to optimize battery management and prevent overheating from triggering protection. When there are voltage fluctuations in the home power grid, use a voltage regulator to buffer the impact. Replace the charging cable with a certified one to ensure the wire gauge is thick enough to avoid impedance. You can also install a smart socket to monitor the load and alert when it exceeds the limit. The root cause may be on the vehicle side—restart the BMS system or visit a 4S shop to check the sensors. Pay attention to daily maintenance: avoid charging in humid environments and regularly calibrate equipment parameters. With this set of operations, the failure rate is significantly reduced.
