Alternating current charging system for electric cars of multiple users

Abstract

The invention relates to a charging system for electric cars, in particular to an alternating current charging system for electric cars of multiple users. An alternating current distribution panel comprises a low-voltage alternating current distribution cabinet, an LCD color display screen, a wireless card reader, an operation keyboard, a bill printer and a surveillance video camera. The low-voltage alternating current distribution cabinet leads a 380 V or 220 V alternating current to a distribution cabinet busbar from the low voltage side of a transformer, and a charging pile control module distributes the electric energy to alternating current charging piles at the front end. The alternating current charging piles each comprise a charging pile body, an electrical module and a metering module, and are fixedly installed beside the positions where the electric cars are parked, connected with the alternating current distribution cabinet through cables and used for providing alternating current power supplies for vehicle-mounted battery chargers of the electric cars. The system meets the requirement for charging the electric cars of the multiple users and allows the multiple users to charge the electric cars at the same time, and therefore both time and space are saved, and the efficiency of charging the electric cars is improved.

Description

technical field [0001] The invention relates to an electric vehicle charging system, in particular to a multi-user electric vehicle AC charging system. Background technique [0002] After nearly 10 years of development, my country's electric vehicles basically have the basis for industrialization development. Key technologies such as batteries, motors, electronic control and system integration have made significant progress. Pure electric vehicles and plug-in hybrid vehicles have begun to be put on the market on a small scale. With the establishment of the new development plan, electric vehicles will usher in a new round of high-speed development opportunities. Electric vehicles not only meet the travel needs of the majority of urban and rural residents, but also comply with the national requirements for energy conservation, emission reduction and economic development. However, there are also many problems in practical applications. For example, there are not enough charging...

AI Technical Summary

Problems solved by technology

[0005] The existing electric vehicle charging system is unreasonably designed, and generally can only charge a single user, that is, one charging pile can only be operated by one user, which not only affects the charging time but also takes up more space. With the increase and development of the number of electric vehicles , there is an urgent need for a collective charging method to match it
