With the continuous breakthrough of renewable energy technologies, new green energy sources such as photovoltaics and wind power generation have become an important supplement to power supply. Electric vehicles are increasingly favored for their zero-polluting emissions, and charging stations responsible for powering electric vehicles are used as electric With the increasing accessibility of the car's ancillary facilities, the safety of its operation has also received increasing attention. With the in-depth development of smart grid customer-end products, Acrylic has introduced electrical equipment for electric vehicle charging stations. Product application solutions for safety and energy metering.
First, the AC charging station product program:
The AC charging pile generally has a power of about 7 kW. The total incoming line is equipped with a power quality analyzer to monitor the power quality of the entire charging pile power supply loop. The incoming circuit also sets the electrical fire monitoring device, the charging management controller, and is responsible for charging and charging control; the single-phase rail type AC energy meter is used for charging energy metering, and the energy data is read by the charging management controller through the RS485 communication port; The line side is equipped with a leakage protection circuit breaker; the charging side is equipped with a miniature circuit breaker with a power supply. .jpg)

Second, small car DC charging pile
The small DC charging pile generally has a power of about 12 kW. The total incoming line is equipped with a power quality analyzer to monitor the power quality of the entire charging pile power supply loop. The incoming circuit also sets up an electrical fire monitoring device and accesses the fire monitoring back-end system. The charging circuit uses three-phase power supply, and its incoming line is equipped with a miniature circuit breaker with leakage protection. The charge management controller is responsible for the external human-machine interface, charging control, reading the electric energy data of the DC electric energy meter, and controlling the opening and closing of the DC charging output circuit breaker. The embedded DC energy meter is equipped with an external Hall sensor or shunt to measure the charging energy. Hall has higher installation convenience and electrical safety performance than its non-contact measurement and shunt. .jpg)

Third, electric bus charging pile
The large electric bus DC charging pile has a large power, about 200kW, and the total incoming line is equipped with a power quality analyzer to monitor the power quality of the entire charging pile power supply loop. At the same time, an electrical fire monitoring device is set up, the charging circuit adopts three-phase power supply, and the incoming line adopts an AC molded case circuit breaker. The three-phase main circuit is configured with a residual current relay that provides indirect contact with electric shock protection. Since such a charging pile consumes a large amount of power, it is recommended to configure a rail type electric energy meter for measuring total electric energy in its three-phase alternating current loop, and to monitor the operating efficiency of the entire charging station in conjunction with a direct current electric energy meter. The charge management controller is responsible for the external human-machine interface, charging control, reading the electric energy data of the DC electric energy meter, and controlling the opening and closing of the DC charging output circuit breaker. .jpg)
