Grid-Friendly Load Profile

Unlike megawatt-scale DC installations that necessitate costly medium-voltage substation expansions and hefty peak-demand utility surcharges, commercial Level 2 charging operates seamlessly within existing 208V/240V/400V distribution transformers.

This allows real estate managers, corporate campuses, and municipality planners to scale charging bays from 4 to 40 ports utilizing dynamic local load management without triggering multi-year grid upgrade moratoriums.

Yangtze River Delta Cluster

Our manufacturing headquarters situated in Kunshan, Jiangsu Province, directly leverages the world's most concentrated power electronics supply ecosystem. Key components—such as metering ICs, Type B RCD current sensors, contactors, and UL-certified flame-retardant enclosures—are sourced within a 50-kilometer radius.

This geographic density accelerates R&D turnaround, compresses BOM costs by 28–35% compared to European or North American assembly, and enables zero-delay rapid prototyping for custom OEM enclosures.

Certified Compliance Architecture

Selling EV charging hardware internationally requires strict adherence to disparate jurisdictional requirements. HizonSun maintains active certifications across ISO 9001, CE (IEC 61851-1, IEC 61851-21-2), CB scheme, CQC, and UL (UL 2594, UL 2231-1/-2, UL 1998).

Our units ship with pre-validated type-test reports, third-party laboratory accreditations, and factory-calibrated Class 1 MID/revenue-grade metering modules required for statutory billing in regulated territories.

Next-Generation Engineering

Technical Roadmap: From Dumb EVSE to Intelligent Energy Nodes

The EVSE manufacturing paradigm in China has transitioned from basic relay-based AC switching boxes to cybersecure, cloud-connected IoT edge computing devices. HizonSun's technology roadmap highlights the electrical, software, and communication milestones engineered directly into our 2026/2027 product lines.

PHASE 01 · INTEGRATED CORE

Multi-Standard Silicon

Consolidated mainboards pairing 32-bit automotive-grade MCUs with dedicated metrology coprocessors. Integrated Type B residual current detection (AC 30mA, DC 6mA) eliminates bulky external DIN-rail RCD modules.

PHASE 02 · CLOUD PROTOCOLS

OCPP 2.0.1 & ISO 15118

Native support for Open Charge Point Protocol 2.0.1 JSON and ISO 15118-2/-20 Plug & Charge. Eliminates RFID fumbling via TLS 1.3 encrypted digital certificates exchanged between EV and the charger controller.

PHASE 03 · GRID SYMBIOSIS

Dynamic Load Balancing (DLB)

Master-slave cluster topologies coordinating up to 64 charging points via RS485 or local mesh Wi-Fi. Real-time CT clamp sensing modulates current delivery to ensure the main breaker threshold is never breached.

PHASE 04 · VEHICLE-TO-EVERYTHING

Bidirectional V2B / V2G

Integration of next-generation onboard bidirectional AC inverter handshake protocols. Enrolling parked commercial and corporate fleet batteries as distributed energy resources for microgrid frequency regulation.

Localized Application Scenarios & Field Engineering

Electrical grid topologies, environmental extremes, and user payment habits differ drastically across major continents. Chinese manufacturing excellence relies on deep regional adaptation—designing hardware that performs reliably whether operating in Scandinavian winters, Middle Eastern deserts, or humid Southeast Asian monsoon climates.

North America (UL Markets)

Tailored for split-phase 120V/240V and 208V 3-phase systems. Our chargers feature Type 1 (SAE J1772) and emerging NACS (SAE J3400) native handles, UL 2231 CCID20 ground fault protection, and NEMA 4X weather-sealed enclosures designed for sub-zero operation.

Europe (CE & MID Regs)

Full conformance with 230V 1-phase and 400V 3-phase TN/TT/IT systems. Integrated Type B residual current monitoring, certified Class B MID meters with visible inspection windows, and Eichrecht-compliant cryptographic signature hardware for German consumer transparency.

Southeast Asia & LATAM

Engineered for high-temperature and extreme-humidity environments. Features anti-fungal PCB conformal coating, tropicalized venting labyrinths with IP55 protection, lightning surge withstand capabilities up to 6kV/10kA, and resilient cellular GSM/4G fallback telemetry.

Depots & Urban Fleets

Heavy-duty dual-gun pedestals engineered with commercial impact resistance (IK10) and anti-vandalism features. Automated backend schedules charge vehicles during low-tariff nighttime hours, preventing expensive peak-rate utility charges.

Frequently Asked Technical & Sourcing Questions

Direct insights from HizonSun's compliance engineers and manufacturing directors regarding certifications, minimum order quantities (MOQ), warranty structures, and cross-border delivery.

What electrical protections are natively integrated into your Level 2 AC chargers?
All HizonSun Level 2 AC charging stations incorporate comprehensive hardware-level electrical safety protections. These include overvoltage protection (>275V AC), undervoltage lockout (<175V AC), overload protection with dynamic curve shutdown, short-circuit protection via integrated high-breaking contactors, lightning surge suppression (up to 6kV / 3kA), and over-temperature rollback sensors positioned directly at the relay terminals and connector cable joints. Crucially, our mainboards include integrated residual direct current detecting devices (RDC-DD) capable of tripping upon sensing DC fault leakage exceeding 6mA and AC leakage exceeding 30mA, fully compliant with IEC 62955 and eliminating the need for expensive external Type B RCD breakers.
How does HizonSun ensure OCPP 1.6J and OCPP 2.0.1 interoperability with third-party software?
Our charging controllers strictly adhere to the Open Charge Alliance (OCA) compliance test criteria. We perform automated conformance testing against major commercial charge point management platforms (including Driivz, AMPECO, ChargeLab, Monta, and GreenFlux). Supported core profiles encompass Remote Trigger, Reservation, Smart Charging (Dynamic Profile Profiles 1, 2, and 3), Local Auth List Management, and secure firmware updates via signed binaries. Field installations connect reliably via Wi-Fi 802.11 b/g/n, 10/100 Ethernet RJ45, or multi-band 4G LTE cellular modems with automatic APN failover logic.
What are your typical OEM lead times, sample policies, and production MOQs?
For evaluation samples and pilot trials, standard unbranded or white-label units are dispatched from our Kunshan warehouse within 3 to 5 business days. For customized OEM production runs (involving tailored faceplates, custom silk-screened logos, and regional connector cable specifications), our standard Minimum Order Quantity (MOQ) begins at 50 units, with a 20-to-25-day production turnaround. Full ODM projects involving bespoke injection mold tooling, unique enclosure metal stamping, or custom PCB layout alterations typically require 45 to 60 days from final CAD sign-off to pilot production.
How are warranty claims, field replacements, and spare parts handled internationally?
HizonSun backs its Level 2 and DC charging hardware with a comprehensive 24-month to 36-month standard manufacturer warranty, extendable up to 5 years via service agreements. Our hardware is built on a modular design philosophy: main control boards, power supplies, contactors, and cable assemblies can be swapped independently in the field without dismounting the enclosure base from the wall or mounting pedestal. For global distributor partners and fleet operators, we provide advance spare parts kits (typically 2–3% buffer stock per 500 units deployed) and deliver 24/7 Tier-2 technical support via remote SSH/OCPP diagnostics.
Can HizonSun level 2 chargers be integrated with on-site solar PV and battery storage?
Yes. Our smart AC chargers feature built-in Solar PV Surplus Charging modes. By integrating with an external smart energy meter or directly communicating with hybrid inverters via RS485 Modbus RTU, the charger continuously adjusts its pilot duty cycle (from 6A up to 32A in 1A increments) to match instantaneous rooftop solar generation. This prevents surplus clean energy from feeding back to the grid at low feed-in tariffs while guaranteeing zero battery drawdown from the main grid during cloudy conditions.
