The problem of electric vehicle running may be caused by the following factors:
1. Long term battery depletion storage: Electric vehicles should keep the battery fully charged during storage, as a depleted state can seriously affect the battery's lifespan. Long term storage with low power can cause chemical reactions inside the battery, accelerate battery aging, lead to a decrease in battery capacity, and thus cause battery runaway.
2. High current discharge: When an electric vehicle is starting, going uphill, or carrying heavy loads, if the motor current is too high, it will cause the battery to discharge quickly and the voltage to drop rapidly. This high current discharge can cause damage to the battery, shorten its lifespan, and increase the risk of battery runaway. When starting, going uphill, or carrying heavy loads, appropriate manpower should be used to avoid excessive battery discharge.
3. Poor charging habits: Some car owners tend to charge their batteries only when they are close to depletion, which can lead to the battery often being in a low state of charge, affecting its performance and lifespan. It is recommended that car owners charge the battery promptly after each ride, keep the battery fully charged for a long time, and regularly perform deep discharge to maintain the battery's capacity and health.
Battery dehydration, sulfurization, and abnormal grounding leakage in various parts of the vehicle may also cause electric vehicles to run out of power. For these issues, car owners should promptly check and take corresponding solutions, such as replenishing battery fluid, cleaning the electrolyte and dirt on the battery cover, checking and repairing ground leakage, etc. If the problem is severe, it is recommended to take the vehicle to a professional repair shop for inspection and maintenance.
