What's the reason for no response when starting the range extender electrically?

Introduction to the reasons for no response when starting the range extender electrically: Abnormal positive and negative voltage: Determine whether the total positive and negative voltage is normal. The voltage of the vehicle should match the voltage of the controller. Ensure that the ignition lock wire is connected to the total positive terminal. If unsure, connect it to the total positive terminal on the controller. Try pulling the starter rope manually to see if it moves. If it doesn't, check if there's any obstruction inside. Remove the large cover on the starter side to inspect. For Lishui controllers, you can judge based on the flashing lights. If everything above is normal, replace the starter. Abnormal range extender battery level: It is not recommended to start the range extender when the battery is fully charged. Generally, it is best to start it when the battery level is between 30%-40%. Starting at full charge does not provide any significant benefits. To protect the environment, it is advisable to start the range extender only when necessary, as battery pollution is more severe than exhaust pollution. Protecting the battery means protecting the environment. It is not recommended to use the range extender when the battery is completely depleted, as the electric start may fail to ignite if there is no power left in the battery.
My car's range extender electric start isn't working, and I've been anxious about it too. After checking, I found there could be quite a few possible factors. The battery is key—if it's low on charge or has corroded poor contact, the starting current supply can't keep up, and the range extender won't respond; blown fuses are the most common issue—usually, check the corresponding position in the fuse box and try replacing it with a new one. Additionally, wiring or relay problems shouldn't be overlooked, like loose connections or aging short circuits, which can cause signal interruptions. Control system malfunctions might also trigger this issue, especially in hybrid models, where the software may need a reset or diagnostic tool check. For safety, if you find it won't start, don't force it—first, park to ensure safety, then troubleshoot step by step or seek professional repair. Regular maintenance of the battery and circuits can reduce such troubles. I personally check the connection cables monthly to avoid sudden breakdowns.
I've experienced the issue of the range extender not starting, which was caused by poor battery condition in winter. Here's a simple troubleshooting path: Start with the easiest solutions first, such as checking if the battery voltage is normal or tightening any loose connections; then inspect the fuse box and replace any blown fuses; if that doesn't work, consider relay or switch failures—burnt contacts can interrupt current flow, and sometimes control modules bug out, requiring a soft reset or code scan. This issue affects driving stability, especially on long trips when the range extender isn't working, as it reduces electric range. So, don't delay inspection if you notice anything unusual. Personally, I make it a habit to get annual electrical system maintenance at the shop—it's worry-free and safe.
