What are the reasons why a tricycle cannot be charged?
2 Answers
Tricycle cannot be charged for the following reasons: Battery damage: If the plates are broken, detached, or severely "sulfated," this phenomenon may occur. Charger failure: If the isolation diode for the output voltage is broken, charging may also fail. Poor plug contact: Due to frequent plugging and unplugging, and because the current at the plug is large, it is prone to overheating and poor contact, which is also a common fault. Battery aging: The battery of an electric vehicle has a service life. When you find that the electric vehicle battery cannot be charged, you need to check whether the battery is within the normal working life range. If it has exceeded the service life, it needs to be replaced or repaired immediately.
I've been riding an electric tricycle for several years and often encounter charging issues. The most common problems are poor contact at the charger plug or a completely faulty charger. Once, an aging socket at home caused unstable power supply. Next are battery issues, especially with older vehicles where battery aging increases internal resistance, preventing charging. Loose connection wires can also cause plugs to disconnect after the vehicle shakes. It's completely normal for charging speed to slow down in cold weather, but if there's no reaction at all, it needs checking. My usual routine is to first check if the power socket is live—testing with another appliance will tell. Then, see if the charger indicator light is on; if not, the charger might be faulty and need replacement. Finally, feel the battery temperature to see if it's too high, which might have triggered protection mode. Always unplug the charger after use to prevent overheating. If none of these steps work, promptly seek a professional repair shop instead of tinkering yourself to avoid safety risks, delays in vehicle use, and impact on livelihood. Regular battery maintenance and dust cleaning can prevent many issues.
