More and more car owners choose to buy electric vehicle. Oil vehicles can go to gas stations when they are out of gas, and electric vehicle can be charged when they are out of power. So how to charge electric vehicle? Fast charging is used when charging in a hurry, and slow charging is sufficient for daily commuting. There is always a portable charging box in the car. In special circumstances, when you really can’t find a charging pile outside, just find a 220V socket. Although the charging is slow, it can still be saved.
There are currently three commonly used charging equipment for electric vehicles: portable charging boxes, AC ev charger, and DC ev charger.
As long as the portable charging box has a charging socket, it can be charged. It takes only a few minutes to find a wall socket at home. So this device involves no additional installation. Most electric vehicle manufacturers are equipped with the standard 16A plug model (in layman’s terms, it is the larger plug of the household air conditioner); because the charging power of the portable charging box with the standard 10A plug is slightly larger, the charging will be slightly faster Some. Of course, there are also some manufacturers of portable charging boxes that have made innovations, adapting to two kinds of AC sockets for household use, standard 16A and standard 10A.
The advantage of the portable charging box is that it is simple and portable. Having said that, the portable charging box is the one with the smallest power among several types of charging equipment, so the charging is slow. You can know the power by pinching your fingers, 220V*16A or 220V*10A. In layman's terms, it means charging two or three kilowatt-hours in about an hour. If the car the owner packs up is a car with a cruising range of 400 to 500 kilometers, if it is charged with a portable charging box, it will take at least one day and one night to charge from basically no power to full.
AC ev charger, (level 2 ev charger) the charging speed is in the middle, and it is also suitable for home use. Especially the mode of driving during the day and charging at night. According to the installation method, there are wall-mounted and floor-mounted. In terms of power, the mainstream of the market is the single-phase AC charging pile 7kW (220v ev charger, 32A ev charger), which matches the 7kW vehicle charger. The AC charging pile is responsible for transmitting single-phase AC power, and the vehicle charger is responsible for converting AC power into high-voltage DC power for the battery. pack charging. If you use a 7kW slow charging pile to charge a car with 400 to 500 battery life on the market, you can charge it at night and drive it during the day the next day. ).
DC ev charger are a type of charging equipment with the largest power. The power is basically distributed from tens of kW to more than 100 kW. Therefore, the requirements for grid power are relatively high, and the charging speed is also fast. The DC charging pile is connected to three-phase alternating current, and the DC charging pile converts the alternating current into direct current, which directly charges the high-voltage DC power battery of the electric vehicle. The higher the power of the DC charging pile, the faster the charging speed relatively speaking (of course, if the maximum charging capacity of the vehicle is exceeded, no matter how powerful the DC charging pile is, there is no way. After all, the charging speed limit of the vehicle is there). Generally, the current mainstream electric vehicles can charge more than 200 kilometers in 30 minutes and more than 300 kilometers in 45 minutes, which is still possible.
