Excuse me. The current electric car charging is. Charge after driving. Or should I charge the battery when it is used up? Please talk to the master. Another 60 V 12A. How long does it take to charge the battery? Wait until you have used it almost! Otherwise, it will be embarrassing if there is no electricity on the road ... Here are some details ... you can refer to them.

How to maintain the battery of electric vehicle in use? The battery should not be charged frequently, because the number of charge and discharge cycles of the battery is certain, generally around 300 times. Frequent battery charging will aggravate the softening and shedding of the active material of the positive plate of the battery, and will also lead to accelerated grid corrosion. Therefore, charging the battery when the power consumption reaches 70% ~ 80% is beneficial to the service life of the battery: it is not appropriate to start and brake frequently when the car is driving, because it consumes a lot of current at this time, which is not good for the battery. When encountering steep slopes or bad road conditions, get off the bus and push (with power) to reduce the large current discharge of the battery, which is easy to damage the battery. Always pay attention to the storage of the battery, if there is insufficient power, charge it in time to prevent vulcanization; When charging, it should be charged until the green light is on, and it is not advisable to stop charging before driving, which is easy to cause vulcanization; When the car is not used for a long time, it should be fully charged, and the battery should be charged once a month to discharge sulfide. In addition, the influence of charger quality on battery life should not be underestimated. The following instructions are for your reference. Why can a good charger extend battery life? For friends who ride electric cars, especially those who are equipped with high-power motors, it will take about six months to a year to replace the batteries. How to prolong the service life of the battery to prolong the battery replacement cycle is a problem that every friend who buys a car is very concerned about. To prolong the service life of the battery, besides riding habit and battery quality, the quality of the charger is more closely related. On the one hand, although the principle of the battery is simple, it has its own charging and discharging characteristics (each charging and discharging process has complex physical and chemical changes), and only a charger that meets this charging characteristic and has pulse repair function can really prolong the service life of the battery; On the other hand, the charger is accompanied by battery charging almost every day. A charger that does not meet the charging characteristics of the battery is equivalent to a "pillow killer" and a "chronic poison" of the battery. Overcharging or under-charging will "poison" the battery for a long time, which is prone to a series of problems that affect the normal service life of the battery, such as water loss and bulging deformation. This is what the industry often says: "The battery is not broken, but charged." The following are several factors that will lead to capacity attenuation during battery charging and discharging: 1. In the process of battery charging and discharging, "vulcanization" will occur, which will affect the battery capacity. Note: Vulcanization means that the electrode plate will be gradually covered by hard lead sulfate crystals due to electrochemical reaction during the use of the battery, which leads to the gradual reduction of the area of the active electrode plate and the decrease of the acid concentration, thus reducing the battery capacity. 2. The charging voltage of the battery is different in winter and summer. If there is no suitable charger that can be adjusted with the environment, the battery will lose water due to overcharging in summer, which will eventually lead to the deformation of the battery, or the mileage will be reduced due to insufficient charging in winter. Note: The battery charging voltage is inversely proportional to the ambient temperature. 3. Due to various factors such as battery usage and factory compatibility errors, there will be voltage imbalance between series batteries, and the battery capacity will be limited by the battery with the lowest voltage. Note: Because most batteries are composed of 3-4 cells 12V connected in series, there will be voltage inconsistency inside the batteries due to factory compatibility errors and other factors. However, the traditional series constant voltage or constant current charging method can not solve the problem of voltage imbalance between batteries, and eventually the battery capacity will be affected by the battery with lower voltage, and the power of other batteries with higher capacity will not be released.
