The difference between fast charging and slow charging is that the charging mode is different, the charging time is different, the charging power is different, and the impact on the battery is different.
Charging modes are different: fast charging does not require car charger conversion, directly connected to the car battery, while slow charging requires charger conversion;
Charging time is different: the charging time of fast charging is generally about 3 hours, while the charging time of slow charging (ordinary charging) is usually about 8 hours or even longer, which can greatly save the charging time of electric vehicles in daily use, for take-out small brothers who often use electric vehicles, the use of fast charging does not even need to be equipped with two batteries;
Charging power is different: Taking Yadi 72v graphene charger as an example, there are two kinds of charger slow charge power: 3A and 4.5A, fast charge power: 7.5A and 10A; The higher the power of the charger, the faster the charging speed, of course, the higher the price; However, it is not recommended to blindly pursue high-power chargers, because it is also necessary to consider whether the charging station supports high-power chargers; Otherwise, the charging speed will not be fast;
The impact on the battery is different: compared with slow charging, fast charging can save most of the charging time, but it has advantages and disadvantages, the faster the charging speed, the greater the damage to the battery, because fast charging will make the battery unit polarized, and ultimately reduce the battery capacity, compared with slow charging, there is no such problem, slow charging can protect the battery to a certain extent;
Fast charge, large voltage and large current in a short time to charge the battery, this charging method is very harmful to the battery, will seriously affect the life of the battery.
Slow charge is to charge with a special charger for electric vehicles, which takes a little longer, but can better protect the battery and increase the service life of electricity.
