What are the reasons for the shorter battery life of lithium battery electric vehicles

Reasons for the shorter battery life of lithium battery electric vehicles 1. Severe vulcanization and water loss, short circuit and open circuit of the plates, broken cells of single batteries, and poor consistency of electric vehicle battery packs are the reasons for the short mileage of electric vehicle lithium batteries. The important reason. 2. The temperature drops: when the temperature of the lithium battery increases, the activity of each active material increases. As soon as the oxygen evolution potential of the positive electrode drops, the oxygen evolution potential of the negative electrode also drops. Therefore, the charging reaction speed is fast during charging, and the charging current is large. The charging voltage is low. 3. The problems of electric vehicles: the common low tire pressure will increase the resistance during riding and increase the power consumption, so the endurance will be low, and the poor brake adjustment will also cause running resistance; in addition to the battery, the motor is also a At the core of electric vehicles, if the motor is worn out and the motor bearings are stuck, the motor's magnets are severely demagnetized, etc., it will cause serious discharge, accelerate the consumption of battery power and shorten the battery life. 4. Resistance problem: The capacity of the lithium battery itself has not changed. What has changed is that the resistance has become larger. Compared with the resistance in summer and winter, if you want to achieve the same power, you can only increase the current output. Under changing circumstances, the battery seems to be draining quickly. In addition, the internal resistance of the lithium battery is related to the temperature, the lower the temperature, the higher the internal resistance, so the consumption is particularly fast in winter. 5. Charger: Chargers have very important uses for lithium batteries in electric vehicles. Some people do not use original chargers to charge electric vehicles. If the charger is not original, it is difficult to make the battery truly meaningful when charging. It is overflowing, and the color of the charger indicator does not necessarily mean that it is fully charged. Therefore, when you use a non-original charger, it will give you a false full charge, and the cruising range will be shortened when riding.
