In recent years more and more private car owners choose electric vehicles to travel, according to authoritative statistics, in 2020, China's electric vehicle ownership in about 4 million, with the matching number of private charging pile applications also increased significantly. At the same time, the national policy is also encouraging and supporting the development of new energy vehicles and their supporting industrial development.
However, at present, the supporting rate of China's charging infrastructure is still far from meeting the growth rate of electric vehicles, the charging pile is difficult to enter the community, the growth rate of private charging pile is obvious, and the demand of owners who want to charge at home is getting stronger and stronger.
Charging pile into the community mainly faces the following difficulties.
(1) the district transformer capacity is limited: according to 7kW / pile reserved power capacity, if the district is equipped with hundreds of parking spaces, only the owners charging capacity of the residential area transformer challenge is great.
(2) with security risks: unified design planning in the early stage, the need to transform and lay wiring, there are certain security risks.
(3) aggravate the peak-valley difference in electricity consumption: the owner charging is mostly concentrated in the peak period of residential electricity consumption, a large number of charging load access, resulting in further increase in the peak-valley difference in residential electricity consumption, intensifying the difficulty of grid peak reduction and valley filling.
(4) aggravate the three-phase imbalance: single-phase AC single pile using single-phase power supply, if concentrated on a phase at the same time, will aggravate the residential area power three-phase imbalance, increasing line losses.
The only way to truly realize the charging pile into the community charging and solve the last mile anxiety for the owners is to solve the above problems.
