Standard Specifications for DC and AC Cables for New Energy Electric Vehicles
With the growth of electric vehicle sales and the expansion of the new energy vehicle industry segment, the number of electric vehicle chargers and charging cables is expected to increase in the future. For example, electric vehicle manufacturers might offer their customers home-installed charging stations or convenient on-board charging connector cables. Even if you don't do this, most EV users think it's a good idea to prepare a charging cable that meets the specifications for your EV. Owning an electric car should come with a 16A or 32A charging cable.
According to adaptive charging, AC charging pile, commonly known as "slow charging", is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide DC power for off-board electric vehicles. Power Battery. It is suitable for families or electric vehicles with their own parking spaces. The charging time is sufficient, and it is not suitable for occasions with temporary power supply or time limit.
However, DC charging piles can be said to be "fast charging". The output of the DC charging pile can be used for direct current to directly charge the power battery of the electric vehicle. The DC charging pile directly outputs DC power to charge the vehicle battery, and the power is generally large. Now the more common ones in the market are 40KW, 60KW, 120KW and so on in big cities. Because the output power of the DC pile is large, it is not suitable for home use, and is suitable for temporary power supplementation in high-speed service areas or places with restrictions. Compared with the AC pile, the charging speed of the DC pile is faster.
The main difference between the two is that the power of the AC pile is small, the charging time is long, and the loss to the battery is small; 1. The power of the DC pile is large, the charging is fast, and the battery loss is large. 2. AC power piles can be installed anywhere, but DC power piles are not suitable for installation at home.
In addition, it should be noted that the higher the power of the charging pile, the higher the installation price, and it is used in commercial and road service areas. Choose cables of different specifications according to customer needs.
