Description

Meet the ultimate solution for residential electric vehicle charging: a high-performance 9.2kW Smart Single-Phase AC EV Charger designed to bring commercial-grade precision and smart automation directly to your home garage. Operating at 40A and 220/230V (50Hz/60Hz), this powerful charging system delivers fast, highly efficient charging tailored for modern electric vehicles. At the core of its electrical engineering is the dedicated Microchip ATM90E26 Energy Monitoring IC, which performs high-accuracy dual-line sensing across both Line and Neutral conditions to measure real-time voltage, current, power factor, frequency, active, reactive, and apparent energy. Boasting an outstanding active power measurement accuracy of ±0.1% and a reactive power accuracy of ±0.2%, this charger ensures you track every watt of consumption with surgical precision. In addition, its dual current-sensing inputs provide an advanced anti-tampering mode, instantly comparing Line and Neutral currents to protect the integrity of your energy data.

Smart IoT Connectivity & Control

Powered by the state-of-the-art ESP32-S3 Microcontroller featuring an dual-core microprocessor running up to 240 MHz, this system bridges raw charging power with modern smart-home convenience. Thanks to integrated 2.4 GHz Wi-Fi and Bluetooth 5 LE, you can easily access real-time charging metrics or customize system settings. Locally, users can monitor their system via an intuitive on-board 4×20 LCD display that continuously cycle through real-time voltage, current, power, energy, frequency, power factor, and temperature readings, managed through user-friendly navigation buttons. For unmatched remote accessibility, the charger features a robust Telegram Bot integration. Through simple text commands sent from your phone—such as “Charger on”, “Charger off”, or “/Read”—you can activate or deactivate the charging cycle, request real-time parameters, and receive instant diagnostic and state updates from anywhere in the world.

Uncompromising Safety & Protection

Safety is meticulously engineered into every layer of this charger’s design. The system incorporates an advanced RCD M0630 Residual Current Device to monitor phase and neutral line imbalances. If a ground fault or insulation issue is detected, the ESP32-S3 triggers an independent high-speed interrupt routine that immediately shuts down the charging current and displays warning alerts on the screen to prevent electrical hazards. Hardwired dual protection is backed by a rugged Schneider 3-Pole 63A Miniature Circuit Breaker (MCB) with Acti9 iC60N technology, alongside dedicated safety fuses on both the phase and neutral lines. Under the hood, dual SPST relays electromechanically isolate the charger in case of anomalies, while a premium HI-LINK AC/DC converter paired with an EMC (electromagnetic compatibility) filter suppresses grid noise and ensures clean, stable power delivery. Combined with intelligent internal temperature monitoring that dynamically triggers a built-in cooling fan if safe thresholds are exceeded, this system guarantees cool, reliable operation even under heavy, continuous loads.
