What are the important reasons for the short life of electric vehicle batteries?

An important reason for the short life of electric vehicle batteries. Many users report that electric vehicle batteries have a short lifespan, which causes problems in less than one year. The reasons for the short life of the battery, in addition to the reasons of the battery itself, such as low purity of lead (some use recycled lead), process formula, plate technology and production accuracy, etc., the following reasons also directly affect the battery life. 1. Charger: The two-stage charger has simple circuit and low price, which is easy to cause voltage instability. Overshoot, floating, and no protection directly affect the battery life. 2. Controller: low price, insufficiency, excessive discharge current, no overload, under voltage, current limiting protection, causing over-discharge damage to the battery, which will potentially affect the battery life. 3. Motor: low-speed, brushless motor, heavy motor, large iron loss, copper loss, magnetic steel demagnetization, low efficiency, no clutch, poor sliding function, resistance is added immediately without power, current consumption is large, relying on large current Discharge drive. In the same situation, it consumes more power than a brushed high-speed motor, and the continuous mileage is shorter, which affects the battery life. 4. Most scooters are equipped with low-speed, brushless motors, the weight of the bike, riding without assistance, resulting in short battery life.
