What are the factors influencing the battery life of electric mopeds?

Factors that affect the battery life of electric mopeds 1. The quality of the battery itself affects the consistency of the battery. The factors that affect the consistency of the battery include the level of battery manufacturing technology and the quality of materials, the level of battery processing management and technological level. High level of technology, advanced processing technology, good materials, high degree of mechanization, and battery consistency must be good. In the process of battery processing, the degree of manual labor is high, which will inevitably affect the consistency of the battery. Therefore, when selecting batteries as an electric vehicle manufacturer, you must check the consistency of the battery, know the processing technology, equipment and processing management of the battery manufacturer, and select the battery performance Stable and consistent battery. 2. The matching level of the electric vehicle's own circuit system. The charger and the controller are closely related to the battery life in the electric vehicle circuit system. In comparison, the charger has a greater impact on the battery than the controller. (1) Insufficient charging. From the perspective of electrochemical reaction, insufficient charging is manifested by the failure of lead sulfate on the anode and cathode plates to completely transform into spongy lead and lead dioxide, which makes the battery capacity insufficient. If the battery is insufficiently charged for a long time, it will cause lead sulfate crystal , The particles increase, so that the plate vulcanizes, and the quality of the battery deteriorates. (2) Overcharge Overcharge will cause the amount of oxygen present at the anode to be greater than the absorption capacity of the cathode, which will increase the internal pressure of the battery, and eventually open the safety valve, causing the gas to overflow, resulting in a decrease in electrolyte. In addition, overcharging will also have an impact on the active material of the cathode and anode plates, which will soften the active material, destroy the grid interface of the positive plate, and make the a molecule become the b molecule, and the b molecule is irreversible. Even if the capacity cannot be restored after recharging, the battery life is greatly shortened. (3) The current density of the controller's influence on battery life. For electric vehicles, current density mainly refers to the running average current and peak current. Whether the controller is over-discharged. The voltage limit protection of electric vehicles is set too low, which may cause over-discharge of the battery. Over-discharge can seriously damage the life of the battery. 3. Whether consumers use electric vehicles correctly or not has a great impact on battery life. (1) If the user does not charge the battery in time every time, the battery is discharged to the final voltage (ie 100% discharge) and then recharged. If the life is more than 200 cycles, then the depth of discharge is 30%, and the battery life will be reduced. Up to 1200 times or more. In other words, the battery life is closely related to the depth of discharge. (2) The user does not charge in time, and the battery is over-discharged to the termination voltage during riding and the power is cut off. As the battery voltage returns to the upper level after the power cut, the electric vehicle resumes the discharge and riding function. This is a repeated over-discharge process for the battery, which has a great impact on the battery life. (3) Riding with excessive load. Riding an electric vehicle under greater than normal load conditions will cause the electric vehicle battery to discharge for a long time with a large current, which has an obvious impact on the battery life.
