Flagship Commercial & Level 2 Hardware Portfolio
Explore our precision-engineered charging stations built at our Kunshan manufacturing campus, combining automotive-grade thermal management, broad interoperability, and intelligent network load balancing.
The Global Commercial & Industrial Status of Level 2 Home & AC Charging
As global electric vehicle penetration accelerates beyond early adopters, the global EV charging infrastructure market has structurally diverged into two complementary operational environments: ultra-fast en-route corridor charging (DCFC) and high-dwell destination/residential replenishment. Level 2 AC charging represents over 78% of all charging events worldwide.
Grid Economics & Off-Peak Shifting
Level 2 charging stations operating between 7kW (32A single-phase, 230V/240V) and 22kW (32A three-phase, 400V) offer the highest capital-to-kilowatt-hour return. While ultra-fast DC systems incur staggering transformer installation and demand charges, Level 2 infrastructure leverages overnight dwell periods, matching low-cost renewable generation curves without stressing local sub-stations.
Chinese Supply Chain Dominance
Suzhou HizonSun Tech Co., Ltd. leverages the complete Yangtze River Delta electronic manufacturing ecosystem. From silicon carbide (SiC) modules and automotive-grade MCUs to high-precision stamping and injection tooling, China produces over 70% of global Level 2 EVSE electronics, ensuring tier-1 global brands achieve competitive BOM costs and rigorous batch consistency.
Stringent Global Compliance Matrix
Exporting AC wallboxes from China requires navigation through fragmented global testing protocols. A single robust OEM platform must satisfy UL 2594/UL 2231 and FCC Part 15 in North America, IEC 61851-1/IEC 62955 (smooth DC residual current protection Type B / 6mA RDC-DD) and CE-RED in Europe, along with regional grid connection codes worldwide.
Technical Taxonomy: Comparing Global Level 2 AC & Destination DC Paradigms
Selecting the appropriate hardware configuration requires clear technical distinctions across electrical topologies, connector interfaces, communication protocols, and safety isolation mechanisms.

|---|---|---|---|---|---|
| Level 2 Single-Phase Smart Wallbox | 208V–240V AC, 1-Phase (50/60Hz) | 7.4kW – 9.6kW (32A – 40A / 48A) | SAE J1772 (Type 1), NACS (SAE J3400) | CCID20 (20mA AC ground fault), Over/Under Voltage, Surge SPD | North American single-family homes, private driveways |
| Level 2 Three-Phase European Wallbox | 400V AC ±10%, 3-Phase + N + PE | 11kW – 22kW (16A – 32A) | IEC 62196-2 (Type 2 Socket / Tethered) | Integrated RDC-DD (6mA DC leakage detection according to IEC 62955) | European residential garages, office parks, commercial hotels |
| Dual-Gun Commercial AC Station | 400V AC 3-Phase / 240V Split-Phase | 22kW + 22kW or 2 x 9.6kW | Dual Type 2 / Dual Type 1 / Dual GB/T | Dual MID-certified energy meters, independent channel breakers | Multi-family developments (MDUs), municipal curbside curbs |
| Compact Fast DC Destination Charger | 380V–480V AC 3-Phase | 20kW – 40kW DC Output (50–1000V) | CCS2, CCS1, GB/T, NACS | Galvanic isolation, insulation resistance monitoring, IMD | Automotive dealerships, fleet workshops, boutique hotels |
Native OCPP 1.6J & 2.0.1 IoT Cloud Connectivity
Modern Level 2 chargers are edge-computing nodes. HizonSun units integrate Wi-Fi, BLE 5.0, 4G LTE-M, and Ethernet communication channels, linking seamlessly to open cloud charge point management systems (CPMS). Built-in Smart Charging Profiles support dynamic power limitation, remote diagnostics, automated firmware-over-the-air (FOTA), and encrypted WebSocket channels (WSS/TLS 1.3).
Active Dynamic Load Balancing (DLB)
Grid supply capacity is the greatest barrier to residential multi-vehicle charging. Our proprietary hardware-integrated DLB controllers monitor aggregate main panel currents using split-core current transformers (CTs) or Modbus/RS485 energy meters. The station adjusts pilot duty cycles in real time (down to 6A increments), ensuring main household breakers never trip during high domestic appliance usage.
ISO 15118 & Seamless Plug & Charge
Moving beyond legacy RFID cards and smartphone applications, our next-generation controller boards incorporate PLC (Powerline Communication) transceivers adhering to ISO 15118-2 and ISO 15118-20. This allows authenticated, automated billing and bidirectional handshaking the instant the connector marries the vehicle inlet.
