As electric vehicles become increasingly common in homes, commercial facilities and public charging environments, charging safety is becoming just as important as charging speed.
The IVY AEC-21Y-G1 Smart Charging Module is designed with safety as a core part of the charging architecture. Rather than relying on a single protection mechanism, the module integrates multiple protection functions to address different electrical and operational risks during the charging process.
With its 14 protection functions, the AEC-21Y-G1 provides a comprehensive safety concept for modern AC EV charging applications.
Among all protection functions, leakage protection is one of the most important features for EV charging applications.
During charging, insulation faults, damaged cables, equipment aging or unexpected electrical leakage can create potential safety risks. The AEC-21Y-G1 integrates leakage protection into the charging module, helping detect abnormal leakage conditions and respond appropriately to protect the charging system.
For residential charging, public charging stations and commercial charging facilities, leakage protection provides an additional safety barrier between the electrical system and the user.
Leakage Protection = Enhanced Safety for People, Vehicles and Charging Equipment.
This makes leakage protection a particularly valuable feature when selecting an integrated EV charging module.
The AEC-21Y-G1 is designed to provide protection against a broad range of abnormal conditions, including:
Emergency Stop Protection
Open Cover Protection
Leakage Protection
Lightning Protection
Overheating Protection
Grounding Protection
Short-Circuit Protection
Overvoltage Protection
Undervoltage Protection
Surge Protection
Electrostatic Protection
Stop Charging When the Battery Is Full
Together, these functions create a multi-layer safety concept covering electrical abnormalities, environmental risks, equipment conditions and charging-status management.

Safety does not mean compromising charging performance.
The AEC-21Y-G1 supports single-phase and three-phase AC charging, with a maximum charging power of 21kW and current options from 16A to 32A. It supports Mode 3 charging and provides Class 1.0 metering accuracy.
The module also integrates smart metering and multiple communication options, including RS485, NFC, Bluetooth and 4G, enabling flexible charging, authorization and remote communication solutions.
The compact DIN-rail design makes the AEC-21Y-G1 suitable for different EV charging equipment architectures. Its customizable design allows manufacturers and system integrators to develop charging solutions according to specific application requirements.
The module is suitable for:
Residential EV charging
Public charging stations
Commercial charging facilities
Long-term rental and electricity-sale applications
New energy vehicle charging systems
With an operating temperature range of -25°C to 70°C, the module is designed for demanding charging environments.
A reliable EV charger needs more than high charging power. It needs intelligent monitoring, accurate metering, dependable communication and, above all, comprehensive protection.
The AEC-21Y-G1 brings these functions together in one integrated AC charging module.
Up to 21kW charging power. Smart metering. Multiple communication options. Comprehensive protection.
And with leakage protection at the heart of its safety architecture, the AEC-21Y-G1 is designed to help charging equipment manufacturers build safer and smarter EV charging solutions.
As EV charging infrastructure continues to expand, safety will remain a fundamental requirement for every charging application.
The AEC-21Y-G1 Smart Charging Module combines powerful AC charging with a comprehensive protection system, providing an integrated solution for manufacturers, system integrators and charging infrastructure developers.
14 Protection Functions. Smart Charging. Safer EV Charging.
