High-Power DC & AC Public Charging Solutions
Field-engineered integrated fast charging pedestals and intelligent AC distribution systems built for ultra-heavy duty public forecourts, commercial plazas, and destination hubs.
The Chinese Power Electronics Supply Chain Advantage
Why leading global operators partner directly with Suzhou HizonSun Tech Co., Ltd. for turnkey procurement, BOM optimization, and rapid engineering iterations.
Silicon Carbide (SiC) Rectifiers
By leveraging China's dense semiconductor cluster in the Yangtze River Delta, our 20kW, 30kW, and 40kW DC charging modules incorporate 3rd-generation SiC MOSFETs. This delivers ultra-wide constant power output (200V–1000V DC), reduces thermal losses by 38%, and guarantees full 96.5% peak power conversion efficiency under extreme grid harmonics.
Full Vertical Integration
We do not operate as simple white-label box builders. From in-house CNC sheet metal laser cutting and automated electrostatic anti-corrosion powder coating (C5-M marine rating available) to custom surface-mount SMT printed circuit boards, every sub-assembly is built, aged, and serialized under rigorous ISO 9001 quality supervision.
Cost Structure & Dual Sourcing
Direct supply-chain agreements with world-class contactor, breaker, and metering vendors (Schneider, ABB, Chint, Phoenix Contact) allow us to reduce bill-of-materials (BOM) capital costs by 30% to 45% compared to Western counterparts without compromising international product compliance or long-term component lifecycle availability.

Eichrecht & Legal Metrology Readiness
For European public fast-charging forecourts requiring calibrated transaction transparency, our DC charging piles integrate certified cryptographic hardware transparency boxes and DC MID energy meters. Session data packets are signed directly at the physical measurement shunt, guaranteeing tamper-proof audit trails for operators and end-users.
Enterprise Tender Requirements & Buyer Intent Analysis
Key technical parameters demanded by institutional charging station investors, utility concessionaires, and fleet electrification directors.
99.5% Operational Uptime SLA
Global CPOs assess chargers not only on initial purchase price, but on Mean Time Between Failures (MTBF) and Mean Time to Repair (MTTR). Our modular power rack architecture supports hot-swappable 30kW/40kW power rectifiers. If a single module encounters an anomaly, the central intelligent power manager isolates it while continuing charging on remaining modules without station outage.
Dynamic Matrix Power Sharing
Fleet operators and highway hubs require dynamic matrix power redistribution. In a dual-gun 180kW or 240kW station, our microsecond CAN-bus controller reallocates rectifier modules in 20kW/30kW increments according to vehicle BMS battery voltage curves, preventing power starvation and eliminating unutilized capacity on idle connectors.
Direct POS & Sovereign Cloud Backend
Eliminate dependency on proprietary walled-garden charging apps. Stations feature integrated outdoor-rated touch screens, EMV Contactless NFC card readers (Visa, Mastercard, Apple Pay), and dual-socket OCPP 1.6J/2.0.1 connectivity that links to any third-party Central System (Driivz, AMPECO, Greenflux, ChargeLab).
EV Charging Technology Evolution: Next-Gen Megawatt & Storage Architecture
How the market is transitioning from conventional standalone chargers to integrated microgrid and ultra-fast charging infrastructures.
Liquid-Cooled 480kW–720kW Ultra-Fast Hubs
With passenger and commercial electric vehicles migrating to 800V and 1000V battery architectures (Porsche Taycan, Hyundai E-GMP, Lotus, heavy-duty e-trucks), traditional forced-air cables become too heavy. Our split-type liquid-cooled terminals deliver continuous 500A–600A output with lightweight cables, providing 10%–80% SOC replenishment in under 12 minutes.
Solar-Storage-Charging (PV+ESS+EV) Microgrids
Grid capacity constraints represent the primary bottleneck for new fast-charging sites. Our 100kWh and 200kWh LFP battery integrated charging stations act as virtual power buffers. They recharge via rooftop solar or low-cost off-peak night electricity and discharge during peak daylight pricing, bypassing expensive substation transformers.
Bidirectional V2G & ISO 15118-20
Electric mobility is shifting from unilateral consumption to bilateral grid stabilization. HizonSun's advanced engineering prototypes incorporate bidirectional AFE (Active Front End) rectifiers compliant with ISO 15118-20, empowering commercial fleets to engage in Frequency Control Ancillary Services (FCAS) and demand-response peak shaving.

Frequently Asked Questions on China EV Charger Manufacturing
In-depth engineering answers addressing compliance, manufacturing capabilities, electrical topologies, and logistics for international purchasers.
What specific certificates do you provide for European and North American customs clearance?
For European tenders, we supply full CB test reports under IEC 61851-1 and IEC 61851-23, CE Declaration of Conformity (DoC) covering LVD (Low Voltage Directive), EMC Class A/B, and RED (Radio Equipment Directive for 4G/RFID). For North America, units are built to UL 2202 (DC fast chargers) and UL 2594 (AC wallboxes) with authorized NRTL (TUV Rheinland / Intertek ETL) markings.
Can your charging stations communicate seamlessly with third-party software platforms via OCPP?
Yes. Our firmware strictly adheres to OCPP 1.6-JSON (including all mandatory profiles: Core, Firmware Management, Local Auth List Management, Reservation, Smart Charging, and Remote Trigger) and is fully upgradeable to OCPP 2.0.1. We have passed interoperability tests with leading platforms such as Driivz, AMPECO, GreenFlux, ChargeLab, and Monta.
How does HizonSun manage thermal dissipation in high-temperature or coastal environments?
Our enclosures feature an IP54 to IP55 dual-chamber layout. The electrical and power electronics modules reside in an isolated duct with intelligent PWM-controlled brushless centrifugal fans and replaceable G4 dust filters. Sensitive logic controllers are hermetically separated. For marine coastal regions, sheet metal receives specialized anti-salt-spray C5-M epoxy coating.
What is the standard production lead time and minimum order quantity (MOQ) for OEM branding?
For standard configurations, sample units ship within 14–20 days; batch production orders (20 to 100 units) require 30–35 calendar days. For OEM projects involving custom cabinet paint colors (RAL match), custom silk-screen logo placement, and branded LCD touch UI firmware, our typical MOQ starts at only 5 to 10 units.
How are warranty claims and spare parts handled across international borders?
Every commercial station comes with a standard 2-year factory hardware warranty, extendable to 5 years. We supply 2% critical spare parts (rectifier modules, main control boards, contactors, charging gun cables) free of charge with volume container orders. Defective modular sub-assemblies can be diagnosed remotely via our cloud telemetry tools and replaced in minutes on-site.
How does the Energy Storage Integrated Charging Pile handle grid power shortages?
Our 100kWh/200kWh LFP storage chargers connect to lower-capacity AC grid feeds (e.g., 30kW–50kW available grid connection). The internal battery stores energy continuously. When an EV plugs in requesting 120kW–160kW DC fast charging, the system automatically pulls from both the battery pack and grid in tandem, enabling high-speed charging without expensive transformer upgrades.
