What Causes a Tricycle Charger to Overheat?

[Angela]

It is caused by the charger's output current being too large, leading to the wires being overheated and scorched due to the high current. Here are some precautions for vehicle charging: Regular inspection: It is generally recommended to inspect the battery every 30,000 kilometers and perform maintenance every 80,000 kilometers. However, very few 4S shops or repair shops can perform such operations, and the lifespan of maintenance-free batteries is relatively fixed. Under normal usage conditions, the battery needs to be replaced every 2-3 years. Excessive charging time: Try to avoid charging the battery at night, and the charging time should not be too long, generally not exceeding 8 hours.

I've been riding a three-wheeled electric bike for seven or eight years and have encountered the charger getting extremely hot to the touch several times. This is usually caused by excessive load or poor heat dissipation during charging, such as charging for too long or the fan being clogged with dust. I remember one summer after charging, the charger was so hot I couldn't touch it, and upon inspection, I found the vent was blocked by debris, and the fan wasn't spinning at all. When charging, it's important not to exceed the recommended time, especially in hot weather, and it's best to charge in a well-ventilated area. If the charger feels excessively hot, it might indicate internal component failure, such as issues with capacitors or resistors, in which case you should stop using it immediately to avoid more serious malfunctions or even fire hazards. I recommend regularly cleaning the fan and heat sink to prevent such problems.

I have a small household electric tricycle, and the charger occasionally gets extremely hot. From an ordinary user's perspective, this is likely related to the battery condition or charging method. For example, an aging battery requires more power to charge, which increases the load on the charger and causes it to heat up. Alternatively, you might be charging for too long, exceeding the recommended duration in the manual. Another issue could be poor heat dissipation—if the charger is placed in a poorly ventilated area or covered, heat can't escape, making it prone to overheating. I've looked up solutions online, and you can start by cleaning the dust to ensure the cooling vents are clear, then try charging again when the temperature is lower. If it still gets unreasonably hot, it's best to replace the charger to avoid safety hazards. Develop good habits—don't charge for too long, and always choose a cool, well-ventilated spot for charging.

The abnormal heating of the tricycle charger may be caused by overload or blocked heat dissipation. Having driven electric vehicles for many years, the common reason is prolonged charging leading to internal overheating, or dust-clogged fans causing poor heat dissipation. It is recommended to immediately stop the charger, allow it to cool, and then check if the vents are obstructed, or verify whether the charging time and ambient temperature are reasonable. If internal components are damaged, replacement is necessary to avoid hazards.
