The difference is as follows:
Charging time, effect on battery, charging mode, charging power supply. Fast charge for half an hour can be charged 80%, slow charge for 6 to 8 hours;
Fast charging will damage the battery to a certain extent, while slow charging will have a better service life;
Fast charging does not require an on-board charger conversion and is directly connected to the in-car battery, while slow charging requires a charger conversion.
Charging power: Taking Yadi 72v graphene charger as an example, there are two kinds of chargers for slow charging power: 3A and 4.5A, fast charging power: 7.5A and 10A, the higher the power of the charger, the faster the charging speed, of course, the higher the price, but 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.
Charging time, impact on battery, battery charging mode. 1, battery charging: fast charge half an hour can be charged 80%, slow charge to 6~8 hours can be full; 2, the impact on the battery: fast charging will certainly destroy the battery slow charging will be better for the life of the battery; 3, battery charging mode: fast charging does not have to be changed according to the car charger, you can directly connect the car battery, slow charging should be changed according to the charger.
