The difference between fast charging and slow charging: First, the speed is different.
< br >
Fast charge generally charges the phone, and it can charge 50 to 70 percent of the electricity every half hour. The slow charge takes two or three hours to reach 50 percent.
< br >
Second, the principle is different.
< br >
Fast charge is to increase the current to achieve a rapid charge to the mobile phone, slow charge is ordinary charging, small flow to the mobile phone fully charged.
< br >
The third is the difference in quality.
< br >
Fast charging appliances and slow charging appliances of the same price, fast charging appliances will break first, because the loss of fast charging appliances is larger.
< br >
Fourth, the price is different. Fast charging devices are slightly more expensive than slow charging devices. The difference is about 20 to 50.
Fast charge refers to high power DC charging. It uses the charging interface of the DC charging pile to convert the alternating current of the grid into direct current, which is transmitted to the fast charging port of the electric vehicle, and the electric energy is directly charged into the battery. It can be charged up to 80% in as little as half an hour.
Slow charge refers to AC charging. It is the charging interface of the AC charging pile, which inputs the alternating current of the grid into the slow charging port of the electric vehicle, converts the alternating current into direct current through the charging machine inside the car, and then inputs the battery to complete the charging.
The general power of AC fast charge is 17 kilowatts, and the general power of AC slow charge is 7 kilowatts, and the fast charge is twice as fast as the slow charge.
