High-Power Floor-Mounted DC Chargers
Explore our export-certified floor-mounted fast chargers, split-type central power cabinets, and smart wallbox units designed for ultra-low MTTR and superior electrical conversion efficiency.
Global EV Megatrends & Floor-Mounted DC Infrastructure
Decarbonization mandates, 800V battery architectures, and heavy commercial fleet electrification are reshaping requirements for high-power DC fast charging infrastructure across international markets.
The global transition toward electrified heavy commercial mobility and long-range passenger vehicles has created an unprecedented demand for reliable, high-power floor-mounted DC fast chargers. Monolithic low-voltage architectures are rapidly becoming obsolete as modern electric vehicle platforms transition to 800V and 1000V nominal battery buses. For Charge Point Operators (CPOs), fleet logistics hubs, and highway corridor developers, selecting an original design manufacturer (ODM) with full-stack vertical integration is no longer simply a matter of hardware procurement—it is a critical determinant of operational uptime, grid resilience, and long-term capital efficiency.
At Suzhou HizonSun Tech Co., Ltd., based in Kunshan, China, we operate at the bleeding edge of power conversion topology. With over 8 years of dedicated industrial experience, our facility bridges the gap between customized mechanical packaging and mission-critical power electronics. Floor-mounted DC chargers represent the heavy cavalry of the EVSE ecosystem: engineered to withstand severe outdoor operational environments (-30°C to +55°C), high grid fluctuations, continuous maximum duty-cycle stress, and abrasive ambient conditions while maintaining peak conversion efficiency exceeding 96%.
Modular Power Electronics & Thermal Durability
Our integrated and split-type floor-mounted DC chargers are built on automotive-grade Silicon Carbide (SiC) and digital DSP controllers, ensuring stable performance across tens of thousands of operational cycles.
Dynamic Matrix Power Allocation
Equipped with intelligent matrix switching contactors, our split-type systems (360kW–720kW) dynamically route 20kW or 30kW high-efficiency sub-modules to multiple dispensers based on individual vehicle state-of-charge (SoC).

Frequently Asked Engineering Questions
Detailed technical responses to the questions most commonly raised by infrastructure project directors, procurement heads, and electrical contractors.
How does HizonSun ensure continuous thermal performance under peak ambient heat?
Our floor-mounted cabinets incorporate positive-pressure isolated cooling tunnels. The heat-dissipating heatsinks of our power modules are enclosed in an independent duct isolated from sensitive control electronics. Variable-frequency EC fans actively modulate airflow according to thermistor readings on power switches and charging cable terminals, preventing thermal derating up to +50°C ambient temperatures.
Can your floor-mounted DC chargers support both 400V legacy and 800V modern EVs?
Yes. Our DC charging modules feature an ultra-wide constant-power output voltage window ranging from 150V DC to 1000V DC. This ensures that legacy 400V platform vehicles receive maximum charging current up to their acceptance limit, while modern 800V architecture vehicles (such as Porsche Taycan, Hyundai E-GMP, and commercial heavy e-trucks) operate at full theoretical fast-charge speeds.
What is the typical lead time and minimum order quantity (MOQ) for custom ODM models?
Standard configuration units are stocked for rapid shipment within 10 to 15 days. For customized ODM projects involving sheet-metal restructuring, unique screen integration, or customized UI/UX firmware modifications, initial prototypes typically require 3 to 4 weeks. Commercial batch production MOQs start flexibly at 2 to 5 units for heavy split-type cabinets, and 10 units for integrated chargers.
How do your chargers handle grid power harmonic distortion and power quality?
Our rectifier stages employ multi-level Active Power Factor Correction (APFC) controlled via 32-bit DSPs. This achieves an input power factor (PF) of >0.99 at loads above 50%, with Total Harmonic Distortion of Current (THDi) strictly maintained below 5%. This conforms to the stringent grid interconnection guidelines enforced by utility providers across the EU and North America.
What payment systems and access management protocols are natively supported?
Our floor-mounted units feature modular interfaces for RFID (ISO/IEC 14443 Type A/B), QR code payment via dynamic mobile apps, and PCI-PTS certified credit card POS terminals (e.g., Nayax, Ingenico, PAX). Over OCPP 1.6-J or 2.0.1, the charger interfaces seamlessly with third-party billing backends and roaming clearinghouses like Hubject and Gireve.
What warranties and after-sales support networks are provided globally?
HizonSun backs its products with a comprehensive 24-month standard manufacturer warranty, extendable up to 5 years via SLA agreements. Supported by 36 global sales and technical service hubs across Europe, South America, North America, and Southeast Asia, we maintain spare parts depots and provide 24/7 remote tier-3 engineering assistance.
