The difference between DC pile and AC pile for electric vehicle charging

According to the adaptive charging, AC charging pile, commonly known as "slow charging", is a kind of power supply device that is fixedly installed outside the electric vehicle, connected to the AC grid, and provides DC power for non-vehicle electric vehicles. Power Battery. It is suitable for families with their own parking space or electric vehicles, and the charging time is sufficient, not suitable for temporary replenishment or time-limited occasions.

However, DC charging posts can be described as "fast charging". The output of a DC charging post can be used for DC power to charge the power battery of an electric vehicle directly. DC charging piles directly output DC power to charge the vehicle battery, and the power is generally larger. The more common ones in the market now are 40KW, 60KW, 120KW, etc. in big cities. Because of the large output power of DC piles, they are not suitable for home use and are suitable for temporary power replenishment in high-speed service areas or places with restrictions. Compared with AC piles, DC piles have faster charging speed.

The main difference between the two is that AC pile has low power, long charging time and low loss of battery; DC pile has high power, fast charging and high loss of battery. AC piles can be installed anywhere, but DC piles are less suitable for installation at home. It should also be noted that the higher the power of the charging pile, the higher the installation price, which is applied in commercial, road service areas, etc.

The use of the gun line of electric vehicle charging post: When using the charging connection to replenish the power to the electric vehicle, the vehicle should be stopped running state and can only be charged in the stationary state. If the electric vehicle cannot start charging, please check whether the electric vehicle is an international charging socket and check whether the electric vehicle prompts a malfunction. If there is a malfunction, please consult a technician in the relevant area. Otherwise, please reinsert the charging gun and try to restart and charge. Precautions needed: Keep the charging connector clean and dry. If it is dirty, please wipe it with a clean and dry cloth. It is strictly forbidden to touch the charging gun core with your hand when charging.
