Electric vehicle battery is charged frequently or recharged after it is discharged?

Some people say that they need to be recharged every day, but others say that they should wait until the battery is used up before recharging the battery. Which one is better? In fact, it’s very simple: if the mileage of a day’s riding is greater than or equal to 50%, then you have to charge it every day (after you are sure that you are no longer using it); if your riding distance is less than 30% of the continued mileage, you You can choose to charge once every two days.　　1. Is it good to charge frequently? 　　 As the discharge becomes deeper and shallower, the number of cycles will increase greatly. Therefore, according to this theory, frequent charging is beneficial to cycle life.　　 But as far as a large number of chargers are currently in circulation on the market, due to price factors and technical level, the chargers have defects such as high failure rate, poor reliability, and low accuracy. Therefore, sometimes charging frequently will affect the service life of the battery. In addition, frequent charging of the battery will aggravate the softening and shedding of the active material on the positive electrode plate of the battery, and will also accelerate the corrosion of the grid.　　Some people may ask, shouldn’t it be charged in time after use, otherwise it will easily cause vulcanization? Yes, but in shallow discharge, the concentration of lead sulfate inside will not be very large, and the crystallization will be slower and less, and it has not become a large crystal. Moreover, our increased floating charge time can prevent vulcanized batteries to a certain extent.　　Second, is the electric vehicle charged every day or the next day? 　　If the mileage of a day’s riding is greater than or equal to 50%, then it must be charged every day (after confirming that it is no longer in use). If the distance you ride is less than 30% of the continued mileage, you can choose to charge it once every two days. If it is less, you can extend it appropriately, but not more than 3 days.　　 In addition, each time you charge, you can properly extend the charging time by about 1-2 hours, which can make your battery fuller. (But after extending the charge for 2 hours, do not continue to charge, otherwise it will be overcharged.) 　　 Three, recharge after discharge? 　　 Empty the battery and recharge, although the number of recharges is reduced, but the discharge is due to the single battery There will always be differences between them that may cause some single cells to be over-discharged, and the charge acceptance of over-discharged batteries will be greatly reduced, causing under-charging failures. In addition, due to the discharge and recharging, the charger will be overloaded for a long time and it is easy to damage the charger.　　 Finally, it is more reasonable to charge once when the battery discharges 50-70% of the power, which is good for the use of the battery. Generally, the battery is best charged when one third of the battery is left. Previous post: Does the new battery voltage drop fast? what is the reason?
