Electric vehicles (EVs) use electricity or other renewable energy sources to store energy. It is becoming popular among consumers for its many advantages, including eco-friendliness, quiet operation, cost reduction, low maintenance requirements, etc. As more people choose EVs, their user scale is expected to expand substantially in the coming years. 

AC EV charger facilities are an important infrastructure for electric vehicle charging, which is significant for promoting the popularization and development of electric vehicles. With the continuous expansion of the global EV market, the demand for AC EV chargers is also growing. Their fast charging capacity and cost-effectiveness make them suitable for wide application across residential and commercial areas. 

The global EV charger market was about $7.2 billion in 2022, and this data is estimated to reach $91.2 billion by 2032.[1]


Understanding the AC EV Chargers

AC EV chargers provide AC power for electric vehicles, playing a role in controlling the power supply while protecting charging safety. They feature varied power ratings and configurations depending on the types of electric vehicles they support and the locations where they will be deployed.

1. Function and Composition of AC EV Chargers

AC EV chargers are the medium between electric vehicles and the power grid. They obtain AC power from the power grid and convert it into DC power for vehicle battery charging. AC EV chargers primarily consist of the input power connection, power conversion unit, user interface, control unit, and protection module. 

The charger draws power from the grid via its input power connection. Within the power conversion unit, essential components, including an AC-to-DC converter, work to transform high-voltage AC into low-voltage DC power. The user interface is equipped with a display and control buttons that allow EV owners to operate the AC EV charger. It provides real-time charging status along with historical usage data. 

The control unit manages and monitors the charging process to ensure the correct flow of electricity. Moreover, the protection module provides temperature monitoring and overcurrent protection to ensure charging safety. Premium-grade EV connect charging stations also boast modular design with separate enclosures to facilitate hassle-free maintenance and upgrading.

2. Working Principle of AC EV Chargers

Firstly, AC EV chargers draw AC electricity from the grid. Next, a converter converts 220V AC power into DC power, which will be directly transmitted to the onboard charger and converted into a current that can directly charge the battery. Advanced power management modules will precisely regulate this conversion process while continuously monitoring voltage, current, and temperature parameters. The filtered DC power is then delivered safely to the vehicle for charging.


Advantages of AC EV Chargers

Reliable AC EV charger solutions deliver many advantages that make them a practical and scalable solution for electric vehicle infrastructure. Their flexible installation options and moderate upfront costs have led to widespread deployment across Europe, China, Southeast Asia, and other markets. Key advantages include the following:
