AC Charging Pile

AC charging piles are fixed in public electric vehicle charging stations and provide AC electricity for the on-board charger of an electric car. They have communication and safety protection functions.

The AC charging pile is equipped with active power filter devices to eliminate harmonics and stabilize the power grid. It also reduces the impact of harmonics on the power metering and billing system and the stability of the communication system.

Human-computer interaction interface

The HEEV-AC series of AC charging piles is an intelligent quick charger that integrates power supply, monitoring, human-machine interaction interface and communication functions. Its modular design makes it easy to maintain and reduces downtime for maintenance. It also offers complete protective functions and multiple charging modes. This model is ideal for quick outdoor charging of pure electric vehicles and hybrid vehicles.

The pile body is made of a metal frame with an insulation layer to prevent short circuits. The input end of the pile is connected to the power grid and the output end is equipped with a charging plug. The pile has a display screen that shows the status of its operation and can be used to input charging parameters. It can be installed in the ground or on the wall of a building.

It is a single-phase AC charging pile that supports various charging modes and payment methods. It ac charging pile can be installed on the ground or in a carport or garage and is compatible with most electric vehicle models. Its simple installation process makes it a convenient option for homeowners.

The AC charging pile has excellent dust-proof and waterproof functions and can work indoors or outdoors (with a rainproof shed). It is designed to be easy to use and is suitable for public use. It supports card charging, code scanning charging and mobile payment. Its standby power consumption is as low as 3W, reducing energy and electricity costs.

Communication interface

An ac charging pile is a wall-mounted electric vehicle charging station that provides AC electric energy for on-board chargers of electric vehicles. It can be installed in public and residential district parking lots, large shopping malls and other indoor and outdoor locations. It can be equipped with a human-computer interaction interface, IC card payment method, running status indicator light and other functions. It can also display charging amount, power, charging time and cost data on the display screen.

The communication interface of the ac charging pile includes CAN (Controller Area Network) and PLC (Power Line Communication). CAN is a high-speed, deterministic communication protocol that is ideal for EV charging control and monitoring. PLC uses existing power lines to transmit information between the EVSE and the grid, eliminating the need for additional communication wiring. However, PLC can be susceptible to noise interference and signal degradation.

The ac charging pile can be connected to the EVSE using either an AC or DC connection. It can be used to charge any type of EV, including hybrid vehicles. It can also be used to charge a plug-in electric motorcycle or bicycle. It can be set to run in different modes, such as a fixed power mode or an automatic mode. It can also provide charging time-sharing, fault state monitoring and historical data logging.

Power supply interface

The power supply interface of an ac charging pile is the part that connects to the vehicle charger. It consists of primary equipment (switches, transformers, lines) and secondary equipment, such as detection, protection and control devices. It also includes active filter devices to eliminate harmonics and stabilize the power grid.

The AC charging pile, which is fixed on the ground, uses special charging interface and conduction mode to provide AC electric energy for electric vehicles with on-board chargers. It also has corresponding communication, charging and safety protection functions. Citizens can swipe a specific card on the human-computer interaction interface to carry out operations such as mode selection, charging time and cost data printing.

Compared to DC charging piles, AC piles are more affordable and can be easily installed on the ground or in residential parking lots. They are also suitable for pure electric buses, electric taxis, electric logistics and electric network car-hailing.

The difference between a DC charging pile and an AC charging pile is that the former has more AC-to-DC power modules inside, resulting in a larger volume. Battery Storage System The wattage of the power modules is also higher. Moreover, the power plugs are different: the DC pile has 9 holes, while the AC pile has 7 holes. The DC pile is connected to a 380V high-voltage cable, while the AC pile is connected to a 220V household cable.

Detection point

The detection point of the ac charging pile is important because it provides the control signal for the connection between the charger and the power battery. It also provides protection against the failure of the charging plug and socket. The detection point is designed using an integrated circuit with PWM signals, which are converted into relatively gentle DC signals. This ensures that the voltage state at the detection point changes smoothly during the switching process.

The ac charging pile can be fixed on the ground or on the wall and is installed in major public spaces, residential areas and charging stations to charge electric vehicles of different voltage levels. It can also support a variety of payment methods and charging modes. In addition, it can display the charging amount, time and cost data.

Compared with DC charging piles, AC charging piles are less expensive and easier to maintain. They are ideal for operational charging services, such as network car-hailing, electric taxis and logistics vehicles. They are also suitable for commercial complexes, shopping malls and other indoor or outdoor parking lots.

In order to improve the functionality and performance of the energy storage charging pile management system, we have analyzed its functional requirements and simulated the function of the control guidance module. The peak and valley periods of the electricity price are studied, and a control algorithm is proposed for the energy storage charging pile to adjust its discharging mode during these period.
