AEC-21Y-G1 Integrated Charging Control Unit: A New Generation of Invisible EV Charger

An electric vehicle charging controller(ev charging control unit), also known as EVSE (Electric Vehicle Supply Equipment) or EVCC (Electric Vehicle Communication Controller), is a device that manages the charging process between the charging station and the electric vehicle. It handles communication, power distribution, and safety issues to ensure a reliable and efficient charging experience.

Here is a detailed description of its functions:

Main functions:

Communication:

The controller establishes communication between the charging station and the electric vehicle, exchanging information such as charging parameters and status updates.

Power management:

It regulates the current to ensure that the electric vehicle receives the correct charging voltage and current.

Safety:

The controller contains safety features such as overload protection, leakage detection, and isolation checks to prevent damage or danger.

Control:

It can control the start/stop of charging, monitor charging progress, and may manage dynamic load balancing of multiple charging stations.

Integration:

Many modern controllers are designed to integrate with smart charging systems, enabling advanced features such as remote monitoring, payment processing, and vehicle-to-grid (V2G).

Controller types:

AC charging controllers: Designed for standard AC charging, they are commonly used in homes and public charging locations.

DC charge controller: used for faster DC charging, commonly found in fast charging stations.

AC/DC hybrid controller: versatile, supports AC and DC charging for a variety of electric vehicles.
