Wholesale Level 3 Charger EV Manufacturer & Supplier

Empowering Global Infrastructure with High-Capacity Commercial DC Fast Charging Stations (30kW - 720kW)

Global Landscape of Level 3 DC Fast Charging

The transition from AC Level 2 destination charging to industrial-grade Level 3 (DC Fast Charging) is the cornerstone of global electric vehicle fleet integration and public infrastructure scaling.

High-Utilization Logistics

For commercial hubs, fleet depots, and highway corridors, charging turnaround speed directly impacts return on investment (ROI). Level 3 DC fast charging, supporting capacities up to 720kW, minimizes dwell times to under 20 minutes, securing critical infrastructure efficiency for freight carriers and logistics firms globally.

Macro Grid Integration

High-voltage infrastructure deployment faces grid connection capacity hurdles. The industry is rapidly adopting smart energy management strategies, combining energy storage systems (BESS), solar PV inputs, and dynamic load balancing software to mitigate local substation stress during peak hours.

Universal Standards

Operators require multi-standard compatibility protocols. Beihai Power engineered solutions support global multi-port protocols including CCS1 (North America), CCS2 (Europe & Central Asia), and GB/T (China), enabling cross-border fleet operations to function seamlessly across diverse vehicle models.

Engineering Smart EVSE Infrastructure

Beihai Power (China Beihai Power Co., Ltd.) is an industry-leading manufacturer specializing in the research, development, and system integration of DC fast-charging and smart AC charging systems. We serve commercial networks, municipal operators, and energy distributors across Central Asia, Southeast Asia, the Middle East, Europe, Africa, South America, and North America.

Our core manufacturing engineering is centered around performance, efficiency, and structural reliability. By building high-efficiency power modules and housing them within custom, climate-resilient cabinets, we deliver stable electrical operations capable of continuous charging profiles under extreme grid and environmental challenges.

Beihai Power Manufacturing Facility Overview

Industrial EVSE Production Process

Step-by-step quality control and engineering excellence from raw sheet metal to fully certified high-power chargers.

1

Material Cutting & Sheet Metal Fabrication

Using state-of-the-art high-precision lasers to cut and shape double-coated anti-corrosion galvanized sheets, ensuring cabinet durability for 15+ years of outdoor operation.

2

Cabinet Assembly & Mechanical Inspection

Welded and sealed to meet IP54/IP55 ingress rating specifications, preserving internal electronics against heavy rain, fine sand dust, and humidity ingress.

3

Electrical Module Integration

Integration of high-grade rectifiers, control boards, smart energy meters, and contactors. Implementation of safety relays for real-time fault detection.

4

Full Unit Functional Testing (FVT)

Every DC pile undergoes dynamic simulation testing up to maximum rated capacity under real load conditions. Insulation and safety systems are systematically validated before packaging.

Technical Roadmap & Custom Adaptations

We provide highly custom electrical modifications. From modular 150kW DC chargers mounted on commercial maintenance vans in Colombia and the US, to large-scale fleet deployments of 24 units in Uzbekistan.

Dynamic Power Allocation

Modern fast charging requires intelligent power sharing. Our double-gun chargers automatically route power modules dynamically according to the vehicle's state of charge (SoC). If one vehicle is charging at 80% SoC (drawing lower power), the system diverts remaining capacity to the secondary gun charging a vehicle at 10% SoC.

V2G and Mobile Off-Grid Solutions

We actively innovate bidirectional energy solutions. The 20kW V2V external power supply allows vehicle-to-vehicle rescue charging, perfect for commercial service operators or remote utility fleets requiring backup energy in emergency conditions.

Our commitment to quality translates to certified reliability. Our charging stations are manufactured in ISO-regulated environments and possess global verification compliance certificates. This ensures safe operations under varied distribution grid topologies worldwide.

We work closely with global design organizations, transport departments, and student energy engineering groups (like the ASME-UDEP Student Chapter) to further global zero-emission transport programs.

Frequently Asked Questions

Answers to key technical and operational questions regarding commercial Level 3 DC fast charging stations.

What is the difference between Level 3 DC fast charging and Level 2 AC?
Level 2 charging delivers Alternating Current (AC) directly to the vehicle's onboard charger, which converts it to DC for battery storage, typically maxing out around 7.4kW to 22kW. Level 3 DC fast charging bypasses the onboard converter and provides high-voltage Direct Current (DC) directly to the battery pack. This enables charging speeds from 30kW up to 720kW, reducing charge time from hours to minutes.
Can the charging system dynamically allocate power to dual guns?
Yes. Our smart double-gun chargers utilize dynamic power matrix routing. Based on the real-time battery management system (BMS) inputs via OCPP, the charger redistributes power modules. For instance, in a 180kW system, it can route 120kW to one vehicle and 60kW to another, maximizing overall utilization and reducing energy loss.
What charging standards do Beihai Power chargers support?
Our EVSE models support all major global standards, including CCS1 (Common in North America), CCS2 (Common in Europe and Central/South America), and GB/T (Chinese Standard). We can configure dual-connector layouts (e.g., CCS2 + GBT or CCS1 + CCS2) depending on custom fleet profiles and regional grid environments.
How do you guarantee cabinet reliability in outdoor desert or saline conditions?
All commercial cabinets are manufactured using galvanized steel sheet metal, treated with anti-corrosion, double-coated outdoor powder paint. The cabinets are engineered to IP54/IP55 standards, with liquid/air thermal paths designed to keep dust, salt-spray, and moisture isolated from the internal power module rectifiers.
Is OCPP 1.6J/2.0.1 integrated into your Level 3 chargers?
Absolutely. OCPP 1.6J (JSON) is natively supported across our DC fast charging range to ensure full integration with backend billing networks, fleet management platforms, and smart charging utility controls. We also offer firmware pathways to upgrade to OCPP 2.0.1, enabling advanced ISO 15118 "Plug & Charge" features.
