High-Performance Charging Units & Smart Commercial Piles
Explore our core product lineup manufactured in our automated Kunshan production facility, engineered strictly to IEC 61851-1, ISO 15118, GB/T, and UL standards.
The 22kW AC Architecture: The Gold Standard for Commercial Infrastructure
Why 3-Phase 400V 32A alternating current charging delivers the optimum capital expenditure (CapEx) to lifetime operational expenditure (OpEx) ratio for modern destination networks.
Grid Utilization & Phase Optimization
The 22kW charging station functions on a 3-phase 400V AC power topology at 32 Amps per phase. For light commercial vehicles and modern passenger EVs fitted with 11kW or 22kW on-board chargers (OBC), this topology extracts maximum charging efficiency without triggering the massive grid upgrade investments demanded by megawatt-level DC chargers.
- Automatic 1-phase (7.4kW) and 3-phase (22kW) auto-switching
- Zero-cross switching relay control minimizes inrush contact arcing
- Built-in residual direct current detecting device (RDC-DD 6mA DC / 30mA AC)
Embedded Cybersecurity & OCPP 2.0.1
As charging networks expand into critical infrastructure, our ODM mainboards incorporate hardware secure elements (HSM / TPM 2.0) guaranteeing end-to-end TLS 1.3 encryption. Full backward compatibility with OCPP 1.6J JSON and forward migration to OCPP 2.0.1 safeguards operator software independence.
- Secure bootloader with dual-bank flash memory roll-back security
- ISO 15118-2 and ISO 15118-20 Plug & Charge public key infrastructure
- Cellular 4G LTE-M / NB-IoT with integrated fallback Ethernet/Wi-Fi
Thermal Endurance & Structural Resilience
Engineered for mission-critical outdoor reliability across severe climates (-35°C to +55°C). Incorporates high-precision sheet metal stampings, anti-UV polycarbonates, and specialized conformal coatings protecting sensitive PCBs against coastal salt-spray, chemical pollutants, and industrial dust.
- Die-cast ADC12 aluminum backplane with passive convective cooling
- IK10 mechanical impact rating resisting vandalism and accidental bumper taps
- Multi-point thermistor array on relay pins and Type 2 socket contacts
Localized Application Scenarios: Engineered for Dwell Time Dynamics
Deploying 22kW EV charging hardware requires strict alignment with parking duration, grid feeder headroom, and local commercial monetization models.
Multi-Dwelling Units (MDUs)
Residential underground garages require scalable, dense clusters where supply current is restricted. Our 22kW units with local mesh Dynamic Load Management (DLM) allow up to 64 wallboxes on a single shared feeder without costly transformer upgrades.
- Sub-billing via MID Class B certified internal meters
- RFID / NFC Mifare local authentication whitelist
Hospitality & Retail Hubs
For hotels, ski resorts, and shopping malls where driver dwell times average 2 to 6 hours, 22kW AC provides 100-150 km of replenished range in under 90 minutes. Dual-gun configurations cut civils and cabling expenditures by 45% per bay.
- POS terminal integration with direct contactless tap-to-pay
- Customizable advertising display & branding fascia
Fleet Depots & Delivery Logistics
Last-mile delivery vans (eLCVs) typically dock for 6 to 10 hours overnight. 22kW chargers allow full overnight replenishment across large delivery fleets while maintaining lower battery degradation compared to high-heat DC charging.
- Automated dispatch scheduling via cloud telematics APIs
- Over-the-air firmware updates with zero service downtime
Public Curbside Municipal Charging
Urban street charging demands slim footprints and impact-hardened enclosures. Our pedestal-mounted dual-socket 22kW solutions feature anti-graffiti finishes, flood sensors, and tilt detection alarms tied into city smart-grid supervisory networks.
- Pedestal design with dual Type 2 lockable shuttered sockets
- Built-in 4G gateway supporting daisy-chained RS485 slave nodes

Complete Vertical Cluster Integration
Situated within the Greater Shanghai electronic component ecosystem, 92% of critical sub-components—such as industrial relays, current transformers, precision sheet metal housings, and silicon sealings—are sourced within a 50 km logistics radius. This shields our ODM clients from international supply chain bottlenecks and cuts component procurement lead times by up to 60%.
Automated SMT & In-Circuit Testing (ICT)
Every control board, power metering board, and communication module is populated via high-speed Yamaha and Panasonic surface-mount production lines. Assemblies undergo 100% automated optical inspection (AOI) followed by full ICT bed-of-nails diagnostic checking, guaranteeing zero cold solder joints and flawless board impedance control.
72-Hour Full-Load Thermal Burn-In
To eliminate early infant mortality rates in field equipment, every completed 22kW EV charger batch undergoes continuous 72-hour full-load thermal burn-in cycling inside elevated temperature chambers (45°C) with real-time simulated EV duty cycling, power oscillation testing, and insulation leakage surveillance before sign-off.
Technological Roadmap: From Static AC Charging to Grid-Interactive Nodes
The transition toward distributed energy resource management (DERMS) requires charging points to act as intelligent, bi-directional energy routers rather than simple current conduits.
Smart Managed Charging & DLB

Frequently Asked Questions: Technical, Commercial & Sourcing Answers
Direct technical feedback from our chief engineering and international logistics teams addressing core buyer considerations for volume ODM supply.
For standard enclosure branding (silk-screen logo and custom packaging), our entry MOQ is 50 units with a manufacturing turnaround of 15-20 business days. For full custom exterior injection moulding or unique industrial metal casings, the tooling cycle takes 35-45 days, after which mass production batches ship in 25-30 days.
Our 22kW commercial models integrate genuine certified Class B MID energy meters featuring sealed tamper-evident glass windows and hardware pulses directly interfaced with the main controller. For German Eichrecht compliance, we support secure transparency software logs (Transparenzsoftware-ready) with signed cryptographic public keys for legal calibration billing.
Yes. In environments paired with rooftop solar PV systems, our hardware incorporates motorized contactor switching that dynamically switches between 1-phase (from 1.4kW to 7.4kW) and 3-phase (up to 22kW). This guarantees that low solar surplus production charges the battery cleanly without pulling expensive deficit energy from the utility grid.
Standard factory warranty is 36 months from bill of lading date, extendable to 5 years via SLA agreements. For volume export clients, we provide 1.5% to 2% complimentary buffer spare parts per container (including replacement relays, LCD screens, power boards, and cable assemblies) to enable immediate local resolution without return freight delays.
