Problems solved by technology

[0004] With the rapid growth of electric vehicles, charging piles have been widely used in order to ensure the travel of electric vehicles. However, at present, most of the charging piles in charging pile stations have an average daily charging hour of less than 2 hours, and the charging piles are on standby for most of the day. Generates a large standby power consumption

Embodiment Construction

[0014] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0015] Such as figure 1 and figure 2 As shown, the charging pile power supply energy-saving automatic control device includes a contactor KM and a control switch K. The contactor KM includes a coil and a contact switch. The control switch K and the coil are connected in series between the neutral line of the power grid and one of the live lines to form a control loop. , one side of the contact switch is connected to the power grid through the access switch K1 (indicated by ac in the figure, the same below), and the other side of the contact switch is connected to the charging pile.

[0016] Specifically, in this example, the contactor KM is a normally open contactor, and the working voltage of the contactor KM is 220Vac....

Abstract

The invention provides a charging pile power supply energy-saving automatic control device. The charging pile power supply energy-saving automatic control device comprises a contactor KM and a controlswitch K. The contactor KM comprises a coil and a contact switch, the control switch K and the coil are connected between a zero line of a power grid and one live wire in series to form a control loop, one side of the contact switch is used for being connected with the power grid, and the other side of the contact switch is used for being connected with a charging pile. The charging pile power supply energy-saving automatic control device can perform on-off control on the power supply of the charging pile according to the time period, and reduce the standby power consumption of the charging pile, thereby being more energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to an automatic control device for power supply and energy saving of charging piles. Background technique [0002] China is currently the world's number one energy producer and consumer. Energy demand and supply continue to grow. With the continuous improvement of my country's economic and social development, the number of automobiles continues to rise. Vigorously developing electric vehicles can speed up fuel substitution and reduce vehicle exhaust emissions. It is of great significance to ensure energy security, promote energy conservation and emission reduction, prevent and control air pollution, and promote my country's transformation from a car country to a car power. [0003] Today, the oil consumed by fuel vehicles accounts for more than half of the world's oil production every year. The rising oil price in recent years shows the shortage of fossil energy availab...
