Who We Are: Engineering High-Power Energy Networks

Beihai Power (China Beihai Power Co., Ltd.) is a premier manufacturer specializing in the research, development, and vertical integration of high-performance DC fast-charging technology and smart AC EVSE systems. By bridging the gap between municipal power grids and modern high-voltage electric vehicle architectures, we provide turn-key charging infrastructure for public networks, government fleets, and commercial depots globally.

Our operational philosophy revolves around high-efficiency power electronics. Our proprietary charging modules feature robust topologies that maximize energy throughput while minimizing thermal wastage. Whether powering municipal buses in Central Asia, highway corridor hubs in South America, or fleet distribution networks in North America, Beihai Power delivers reliable hardware configured for extreme operational envelopes.

Global Industrial Status & Evolving Procurement Demands

Insights into high-capacity charging architecture, system integration, and global distribution trends.

1. Global Infrastructure & Commercial Trends

The global EV infrastructure market has shifted from destination low-power AC charging to corridor-focused, high-power DC fast-charging networks. Fleet operators, commercial real estate developers, and utility providers now demand scalable, future-proof stations capable of handling 800V and 1000V electric vehicle architectures. This paradigm shift requires intelligent power routing, grid dynamic load balancing, and multi-protocol compliance (CCS1, CCS2, NACS, GB/T) to protect capital investments over long-term deployments.

2. The Chinese Supply Chain Advantage

Manufacturing EVSE hardware requires deep vertical integration. By operating our factory in China's advanced manufacturing hubs, Beihai Power leverages a world-class supply chain cluster. This proximity grants us direct access to high-grade magnetic components, industrial-class semiconductor modules, advanced thermal cooling technologies, and raw materials. The result is a highly efficient manufacturing framework that shortens prototyping cycles, ensures rigorous assembly standards, and delivers cost-competitive solutions without sacrificing component longevity.

3. Localized Deployment Environments

EV chargers must withstand diverse external factors. Heavy-duty fleet facilities in cold climates require specialized low-temperature battery packs and heating elements, while public stations in South America and the Middle East need high ingress protection (IP55/IP65) and thermal management systems to handle high ambient heat. Beihai Power engineers chargers that adapt dynamically, utilizing state-of-the-art power sharing algorithms to preserve component integrity under extreme operating temperatures and grid fluctuations.

Industrial EVSE Production Process

Our end-to-end quality assurance workflow ensures structural and electrical integrity for every unit.

01

Material Cutting

High-precision fiber laser systems cut raw structural alloys, guaranteeing exact tolerance limits for rugged outdoor cabinet assemblies.

02

Sheet Metal Fabrication

Automated press brakes bend and shape the chassis, applying anti-corrosion zinc coatings for long-term resistance to environmental weathering.

03

Cabinet Assembly

Skilled technicians join the structural frameworks, integrating internal mounting brackets, ventilation ducts, and environmental seals.

04

Inspection & Testing

Every structural shell undergoes structural alignment checks and water ingress simulation to verify compliance with IP enclosure standards.

05

Module Manufacturing

Our electronics cleanrooms assemble the high-efficiency charging power modules, focusing on precision surface mount technology (SMT) and thermal interfaces.

06

Wiring & Integration

The cabinet shell is integrated with the power modules, main control boards, auxiliary power supplies, high-voltage contactors, and busbars.

07

Functional Testing (FVT)

All finished units undergo Full Unit Functional Verification Testing, simulating real-world charging sequences under extreme thermal loads.

Empowering Global EV Infrastructure with Custom Solutions

From custom fleet solutions in South America to high-volume infrastructure deployment in Central Asia.

Industrial Scalability & Deep Customization

We believe that charging infrastructure should adapt to local requirements. For example, Beihai Power engineered and deployed a custom 150kW Mobile DC Fast-Charging Solution integrated into commercial vans, configured to operate within specialized grids in Colombia and the USA. Additionally, our high-volume production facilities successfully shipped 24 customized DC fast-charging units to Uzbekistan to support state-run public transport infrastructure.

Our commitment to tech innovation goes beyond commercial projects. We actively partner with engineering bodies, such as the ASME-UDEP Student Chapter, supporting the development of advanced energy technologies and the next generation of power engineers.

Industrial FAQ: Key Insights for EVSE Buyers

Technical guidance and answers to common procurement questions from our engineering department.

What is the conversion efficiency rating of Beihai Power charging modules?
Our high-efficiency charging power modules achieve an efficiency rating of up to 96.5%. This high conversion rate minimizes heat generation, reduces operational costs for site owners, and improves reliability compared to standard modules.
Do your charging piles support OCPP 1.6J and OCPP 2.0.1 protocols?
Yes. All Beihai Power DC charging stations support the OCPP 1.6 JSON protocol, and can be configured for OCPP 2.0.1. This ensures seamless integration with third-party billing, user authorization, and network management software.
How does your equipment manage charging in high ambient temperatures?
Our systems feature smart thermal derating and optimized air duct designs. For high-output applications (360kW and above), we use liquid cooling systems to maintain optimal temperatures and prevent overheating, even in hot climates.
Can Beihai Power customize products for specific grid requirements?
Yes. We offer customization for grid standards (including 3-phase systems and wide voltage inputs) as well as custom mechanical cabinet enclosures, connector cables, and branding options to meet local specifications.
