What is the reason why the electric tricycle always shows a red light when charging?

The reason why the electric tricycle always shows a red light when charging may be due to a charger malfunction, battery dehydration failure, or a short circuit in one of the battery cells. Here is the relevant information: Introduction: An electric tricycle is a three-wheeled transport vehicle powered by a battery and driven by a motor, used for carrying goods or passengers. Electric tricycles are equipped with tubular high-capacity, left and right lining, deep-discharge, traction-type batteries, which can meet the requirements of long working hours and continuous discharge. The battery can normally be used for two years without a decrease in capacity. Battery: A battery, also known as an accumulator, is a type of cell that converts chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte.
Last time my neighbor's electric tricycle had the same issue—the charger's red light stayed on all night without turning green. I checked it for him and found the charger's cooling vents were blocked by a rag, and it felt scalding to the touch. In such cases, poor heat dissipation triggers the charger's automatic protection. It could also be a poor socket connection; swapping the cable fixed it immediately. If the vehicle was left out in the rain, mud clogging the charging port could also cause the red light. A repair shop technician mentioned that if the battery is swollen, the charger detects an abnormality and refuses to turn green. The simplest solution is to try a friend's identical charger to rule out charger issues before checking the battery. Avoid random repairs, as it's easy to damage the circuit board.
