With the popularization of new energy vehicles, as an exclusive "must-have", the quality and convenience of charging station products directly affect the user experience of car owners.

　　There are many different brands and types of charging pile products on the market, which can be divided into two categories based on the different charging forms: slow charging AC charging pile and fast charging DC charging pile. There are two types of AC charging stations: wall mounted and floor mounted, which have the advantages of small footprint and convenient installation, making them very suitable for use as private charging stations at home.

　　How do new car owners and potential car owners choose high-quality AC charging stations? How do I apply for installation? EV Vision brings you a detailed and in-depth understanding.

　　220V single-phase AC charging pile VS380V three-phase AC charging pile

　　At present, most car owners install 220V single-phase AC charging stations that are compatible with car manufacturers at home. The so-called single-phase AC charging pile refers to the use of a single-phase full bridge circuit to rectify AC into DC. Nowadays, there are also ways to directly convert AC into DC using switch circuits, and the charging voltage can be automatically adjusted to achieve strong and floating charging purposes.

　　The advantages of this type of charging pile are its low cost and convenient installation, which can be retrofitted in general parking lots; Low valley electricity in the evening of the power grid can be used for charging, with lower charging costs, lower charging current, and relatively stable voltage, which can ensure the safety of the power battery and extend its service life. However, this type of charging station also has its own shortcomings, that is, the overall charging time is too long, which is difficult to meet the needs of emergency charging and long range of vehicles. Moreover, civilian 220V AC electricity adopts a tiered electricity price. If electric vehicles are frequently charged, the electricity price at home may become a third tier electricity price within 2-3 months, after all, electric vehicles consume much more electricity than household appliances, Charging once may consume at least ten kilowatt hours of electricity. But even when using the third tier electricity price, some people have calculated that it is still more economical than the cost of refueling a gasoline car, but it only drags down other household electricity and turns it into high priced electricity.
