Why Does a New Energy Vehicle Suddenly Lose Power?
2 Answers
Possible reasons are as follows: poor contact between the battery power output plug and socket; failure of the speed control handle; power signal system failure. Below are detailed explanations of the specific reasons: 1. Poor contact between the battery power output plug and socket: Generally, it may be caused by wear and oxidation over time, leading to poor internal circuit contact. 2. Failure of the speed control handle: Usually, it's due to poor contact among the three wires inside the speed control handle, typically red, gray, and black, or red, green, and black, with the gray or green wire being the output signal line of the handle. It's best to cut off the middle connector of the speed control handle's connecting wires, reconnect them according to the color difference, and then wrap them securely with insulating tape for foolproof safety. 3. Power signal system failure: If the electric vehicle is highly intelligent, it may also experience power loss. This is mainly manifested in damage to the ignition lock or poor contact between the controller and the ignition lock signal line. The simplest solution is to activate the keyless function.
I've also experienced sudden power loss while driving a new energy vehicle. It happened on the highway and I was so scared that I immediately pulled over. The most common causes are either the battery running out of power instantly or a blown fuse in the high-voltage system. Think about it - electric vehicles mainly rely on large batteries for power. If there's an error in the Battery Management System (BMS), or if charging is interrupted midway causing voltage instability, it can trigger power loss. Additionally, loose wiring or short circuits are major hazards, especially when driving on bumpy roads that can shake connectors.
If this happens, don't panic. First turn on hazard lights and find a safe place to park. Check the dashboard for error codes, such as battery warnings or system failure alerts. Then try restarting the vehicle - sometimes a simple reboot can restore normal operation. If that doesn't work, you'll need to contact a professional repair shop for towing and inspection.
For daily maintenance, pay attention to regular battery care. Don't wait until it's completely drained to recharge. You can install an APP to monitor battery health, which can significantly reduce sudden risks. Remember, safety first - don't take risks by forcing the vehicle to keep running!
