ODM Level 3 Charging Station Suppliers & Supplier

Level 1 (120V AC, 1-2kW) and Level 2 (208V-240V/400V AC, 3.5kW-22kW) supply alternating current to the vehicle's onboard charger (OBC), which rectifies AC into DC to charge the battery pack. In contrast, Level 3 Charging Stations—universally known as Direct Current Fast Chargers (DCFC)—convert high-voltage three-phase AC grid electricity into direct current inside the charging station housing itself. By bypassing the physical size, thermal, and weight constraints of an onboard vehicle rectifier, Level 3 stations can inject between 20kW and over 720kW of DC power directly into the battery pack, dramatically compressing charging times from several hours to 10–30 minutes.

For power levels up to 180kW–240kW operating under 250A continuous current, we utilize forced-air cooling designs featuring segregated airflow ducts, variable-speed fan arrays, and high-efficiency heat sinks that isolate sensitive control boards from dusty outside air (IP54/IP55 rated). When charging currents exceed 300A to 500A—such as in 360kW to 720kW systems—we incorporate closed-loop liquid-cooled cable assemblies and chilled-coolant circulation systems within the dispenser. This active liquid cooling dissipates heat directly from the cable conductors and terminal pins, maintaining safe ergonomic touch temperatures for drivers.

HizonSun designs chargers to meet all globally recognized standards within our unified architecture. We supply Combined Charging System 2 (CCS2) for Europe, South America, and Australasia; Combined Charging System 1 (CCS1) and North American Charging Standard (NACS / SAE J3400) for North America; GB/T 20234.3 for mainland China and affiliated trading partners; and CHAdeMO on designated commercial models. Our software controllers utilize universal communication codecs capable of auto-detecting the attached EV protocol.

Yes. Every station comes standard with an open, non-proprietary OCPP 1.6-JSON client, with optional support for OCPP 2.0.1. This ensures immediate interoperability with major global Charge Point Operator (CPO) management platforms such as Driivz, AMPECO, Greenflux, ChargeLab, and custom proprietary cloud backends. Communication interfaces include dual high-speed Ethernet ports, cellular 4G/LTE modems, and local Wi-Fi with TLS 1.3 cryptographic security.

An Integrated DC Charging Pile houses both the power electronics modules and the user-facing dispensers in a single cabinet. This is compact and ideal for sites with 1 to 4 parking bays. In contrast, a Split-Type architecture (such as our 360kW–720kW systems) separates the heavy, noisy power conversion electronics into a centralized power bank cabinet placed in a utility area, connecting via DC bus lines to slender, user-friendly dispenser pedestals up to 50 meters away. This layout saves prime parking space, simplifies routine module servicing, and dynamically routes power across 8 to 12 charging bays.

An energy storage integrated system (featuring 100kWh or 200kWh Lithium Iron Phosphate / LFP battery banks) is ideal when local grid capacity is restricted (e.g., only 30kW–50kW available at the transformer), utility connection upgrades are prohibitively costly, or long transformer lead times would delay project commissioning. The battery charges continuously at low power or utilizes co-located solar PV during daylight hours, then discharges at full 120kW–200kW power when an electric vehicle connects, mitigating peak utility demand penalties.
