What are the reasons why an electric vehicle cannot start after stalling?
1 Answers
Electric vehicles cannot start after stalling due to poor contact between the battery and the vehicle, blown fuse tubes, poor contact at battery terminals or plugs, loose or broken battery wires, or loose and disconnected controller power wires. The solutions are as follows: 1. Avoid storing the battery in a discharged state: A discharged state occurs when the battery is not recharged promptly after use. In this state, sulfation is likely to occur, where lead sulfate crystals form on the electrode plates, blocking ion channels and leading to insufficient charging and reduced battery capacity. The longer the battery remains unused in a discharged state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its lifespan. 2. Regular inspection: During use, if the electric bicycle's range suddenly drops by more than ten kilometers in a short period, it is likely that at least one battery in the pack has issues such as broken cells, softened electrode plates, or shedding of active material from the plates, leading to short-circuiting. In such cases, promptly visit a professional battery repair facility for inspection, repair, or replacement. 3. Avoid high-current discharge: When starting, carrying passengers, or climbing hills, it is best to use pedal assistance to minimize high-current discharge. High-current discharge can easily lead to lead sulfate crystallization, damaging the physical properties of the battery's electrode plates.
