Enterprise Level 3 DC Fast Charging & Energy Storage Lineup
Comprehensive portfolio from high-efficiency 20kW destination DC wallboxes to 720kW split-architecture megawatt hubs and battery-integrated fast chargers, all built to rigorous international standards.
Global Landscape of Level 3 DC Fast Charging Infrastructure
Analyzing the pivotal shift from destination Level 2 AC to high-throughput Direct Current Fast Charging (DCFC) across global transit corridors, commercial hubs, and high-utilization fleet depots.
Executive Summary: The Transition to 800V/1000V DC Hypercharging
The electric mobility ecosystem has crossed an irreversible inflection point. While AC Level 2 (7kW–22kW) charging fulfills overnight residential dwelling, commercial return-on-investment (ROI) is overwhelmingly dictated by Level 3 Direct Current Fast Charging (DCFC). As modern battery architectures transition rapidly from 400V packs toward 800V and 1000V platforms (such as Porsche Taycan, Hyundai E-GMP, BYD e-Platform 3.0, and commercial e-trucks), charging downtime is reduced from hours to mere minutes. Original Equipment Manufacturers (OEMs) and Charge Point Operators (CPOs) require scalable, high-efficiency Level 3 platforms capable of dynamic power dispatch, high thermal endurance, and seamless protocol interoperability.

Megawatt Charging Systems (MCS) for Heavy Freight
While passenger electric cars top out near 350kW–400kW, Class 8 commercial tractors and long-haul buses necessitate 1MW to 3.75MW charging rails. The MCS standard (up to 1250V and 3000A) is currently in development at HizonSun, integrating ultra-dense liquid-cooled power matrix cabinets with robotic cable management systems.
Bi-Directional V2G (Vehicle-to-Grid) Power Inversion
Level 3 DC chargers are evolving from one-way power consumers into bi-directional grid stabilizers. Our dual-active bridge (DAB) topologies and active front-end (AFE) rectifiers permit controlled power return from EV battery packs back into local facilities or regional utility grids during peak emergency events.
