Frequently Asked Questions by Engineering Buyers
Direct technical clarifications on grid connectivity, electrical topologies, compliance procedures, and custom OEM manufacturing lead times.
What are the key technical advantages of selecting a 20kW-40kW wall-mounted DC fast charger over high-power AC Level-2 (22kW) charging stations?
While a three-phase 22kW AC charger outputs theoretical alternating current, the real-world charging speed is completely throttled by the electric vehicle's internal On-Board Charger (OBC). More than 85% of modern electric passenger vehicles and commercial delivery vans are equipped with OBCs rated at only 7.4kW (single-phase) or 11kW (three-phase), rendering a 22kW AC station incapable of delivering more than 11kW to the battery.
A 20kW to 40kW wall-mounted DC charger rectifies grid AC into regulated high-voltage DC internally, feeding direct power into the traction battery pack via CCS2, CCS1, GB/T, or NACS connectors. This achieves genuine 20kW–40kW power flow regardless of OBC limitations, slashing dwell times by half or more for commercial fleets, workshop turnarounds, and retail patrons.
What electrical service and transformer infrastructure are required to support a 30kW or 40kW wall-mounted DC charger?
Our 30kW and 40kW wall-mounted DC chargers are designed to operate from standard 3-phase commercial electrical supplies: 380V/400V/415V AC (50/60Hz) for European/IEC territories, and 480V AC (or 208V/240V via intermediate autotransformers) for North American markets. For a 30kW system, the continuous current draw is approximately 45A to 50A per phase; for a 40kW unit, continuous current is approximately 60A to 65A per phase.
Because these current levels comfortably fit within standard commercial main distribution panels (such as 100A or 125A 3-phase feeds), installation does not require the expensive utility medium-voltage transformers or dedicated civil switchgear needed for 120kW+ pedestal chargers.
How does the charger handle thermal dissipation in enclosed spaces or extreme ambient heat up to 50°C?
Our wall-mounted DC platforms employ an isolated dual-channel forced-air thermal design. High-heat components (power modules, inductors, and heat-sink blocks) reside in a dedicated airflow duct isolated by IP54/IP55 seals from the sensitive central controller, metrology boards, and communications modules.
Variable-speed PWM industrial fans dynamically adjust cooling flow according to internal junction temperature probes. If ambient temperatures exceed +50°C under direct solar radiation, the firmware automatically triggers intelligent thermal derating to sustain safe, continuous charging without catastrophic emergency trip-outs.
Can HizonSun chargers be integrated into third-party OCPP cloud backends and regional payment gateways?
Yes. All HizonSun chargers implement standard OCPP 1.6-JSON (Open Charge Point Protocol) with native upgrade paths to OCPP 2.0.1. Our firmware has been validated against major global Central Management Systems (CMS) including Driivz, AMPECO, ChargeLab, EV Connect, and GreenFlux.
We provide full white-label configuration of WebSocket URIs, TLS encryption certificates, basic/digest authentication, and Smart Charging profiles (Core, FirmwareManagement, SmartCharging, RemoteTrigger). For payment processing, the charger supports direct RFID reader authorization, QR code redirection to local mobile web payment pages, or integration with embedded Nayax/Ingenico POS payment terminals.
What is the minimum order quantity (MOQ) and production turnaround for custom OEM/ODM orders?
For standard branded catalog evaluations, we support sample orders with an MOQ of 1 to 2 units for engineering trials and bench testing. For custom OEM projects (including silk-screened logos, customized UI boot logos, and specific connector lengths), our baseline MOQ starts at 20 units.
For extensive ODM projects requiring custom sheet-metal tooling, bespoke structural alterations, or private label certification listings, the standard engineering development cycle is 6 to 8 weeks, with mass production batch delivery taking 25 to 35 calendar days from final drawing freeze.
