- Smart charging profiles for utility Time-of-Use (TOU) tariffs
Technical Architecture & Industrial Taxonomy of Level 2 AC Systems
In electric mobility ecosystems, the Level 2 AC charger functions fundamentally as an advanced Electric Vehicle Supply Equipment (EVSE) gateway. Rather than converting AC to DC internally, the Level 2 charger negotiates safety handshakes, establishes maximum current capabilities through Pulse Width Modulation (PWM) pilot signaling over the Control Pilot (CP) pin, and switches primary contactors to deliver safe, alternating current to the vehicle's onboard charger (OBC).
Suzhou HizonSun Tech Co., Ltd. architects residential and destination AC charging systems from its state-of-the-art 10,000 m² manufacturing plant in Kunshan, China. Serving automakers, charging operators, and international distributors across more than 40 countries, our OEM/ODM assembly protocols harmonize mechanical robustness, thermal dissipating chassis engineering, and automotive-grade electrical safety.
"The modern residential Level 2 EVSE is no longer an isolated electrical appliance; it is an intelligent energy asset orchestrating building load capacity, distributed solar arrays, and fluctuating utility tariffs."

Proprietary Functional Hardware Architecture
Every HizonSun OEM Level 2 platform is structured around a compartmentalized dual-board system architecture:
1. Main High-Voltage Switching Board: Engineered with wide creepage and clearance distances exceeding IEC 60664-1 standards. Heavy copper traces (3oz–4oz) withstand sustained 48A thermal stress without delamination. Integrated latching mechanical contactors minimize phantom power consumption during standby mode (< 2W) while mitigating welding risks via auxiliary feedback sensors.
2. Low-Voltage Intelligent Microcontroller (MCU) Core: Powered by dual-core ARM Cortex-M architecture with hardware-isolated cryptography. Manages high-precision metering (class 1.0 or MID-certified billing accuracy), multi-frequency RFID (Mifare, ISO 14443A/B, NFC), Wi-Fi 802.11 b/g/n, Bluetooth 5.0 Low Energy, and optional 4G LTE-M CAT-1 modems.
