Accelerating Global Charging Station Infrastructure with High-Performance Power Electronics

The global EV transition is no longer a localized phenomenon; it has evolved into a complex macroeconomic challenge. Standard off-the-shelf hardware is insufficient for high-density public hubs, municipal fleet yards, and heavy-duty logistics corridors. These environments require specialized infrastructure built on core electrical engineering reliability.

Beihai Power (China Beihai Power Co., Ltd.) is a specialized manufacturer dedicated to the innovation of DC fast-charging technology and smart AC charging technology. We bridge the gap between complex energy requirements and reliable infrastructure delivery for governments and commercial clients across Central Asia, Southeast Asia, the Middle East, Europe, Africa, South America, and North America.

By focusing on the performance of our integrated charging modules, we provide high-efficiency power solutions that ensure faster, safer, and more stable energy transfer for large-scale vehicle infrastructure projects.

Unrivaled Advantages of China's Smart EVSE Manufacturing Ecosystem

Why sourcing directly from China's premier industrial clusters offers unparalleled cost, timeline, and engineering execution benefits.

Vertically Integrated Supply Chain

Our proximity to primary lithium, magnetic components, semiconductors, and precision metal fabrication allows us to source raw components with zero transit lag. This vertical integration keeps pricing competitive while ensuring rapid delivery schedules.

Agile OEM & ODM Customization

Unlike rigid western assemblers, our engineering teams modify cabinet layouts, power delivery profiles, software integrations (OCPP/Modbus), and dynamic load balancing systems to meet site-specific requirements.

Rigorous Compliance & Validation

Our production facilities employ advanced testing instruments, including automated grid simulators, thermal chambers, and simulated high-utilization stress tests. We guarantee performance stability across global power grids.

EVSE Production Process & Technical Flow

From raw materials to shipping, how we build and validate industrial-grade EVSE units.

01

Material Cutting

Ultra-precise laser cutting of heavy-gauge steel and aluminum sheets ensures maximum structural integrity, tolerance adherence, and outdoor durability.

02

Sheet Metal Fabrication

CNC press brakes and automated forming create robust, double-wall enclosures with NEMA 4/IP54/IP55 weatherproofing and IK10 impact resistance.

03

Cabinet Assembly

Anti-corrosion sealing, thermal insulation padding, and secure locking mechanisms are integrated to handle harsh environments.

04

Cabinet Inspection & Testing

Weld tests, IP moisture testing, and structural stress validation verify structural integrity before electrical assembly.

05

Electrical Module Manufacturing

Assembly of high-efficiency charging modules (30kW, 40kW, 50kW), featuring SiC (Silicon Carbide) MOSFETs for low thermal loss and high reliability.

06

Wiring & Assembly

Certified electrical technicians handle terminal block termination, busbar installations, and control board configurations.

07

Functional Testing (FVT)

Simulating maximum power output, fault conditions, high temperatures, and network connectivity ensures flawless operation prior to shipment.

Empowering Global EV Infrastructure with Tailored Charging Solutions

Our portfolio includes high-capacity 480kW charging units and compact commercial charging stations (20kW, 30kW, 40kW). Designed for reliability, these solutions are built for high-utilization environments, including municipal depots, public parking facilities, and freight corridors.

Industrial-Scale Manufacturing

We combine manufacturing capacity with strict quality control. From handling bulk orders—such as our recent delivery of 24 custom-configured DC fast-charging piles to Uzbekistan—to preparing sample batches for international export, we ensure timely delivery.

Deep Customization & Intelligent Integration

We develop adaptations tailored to your requirements, including a 150kW Mobile DC Fast-Charging Solution integrated into commercial vans. This system was designed to meet specific grid and environmental needs for clients in Colombia and the USA.

Localized Application Scenarios & Turnkey Solutions

Adapting hardware and software configurations to meet unique geographical and operational conditions.

Heavy-Duty Logistics & Fleet Charging

For heavy transport hubs, high-output liquid-cooled DC cabinets (360kW to 960kW) provide fast turnaround times. These systems use dynamic, software-controlled power allocation to protect battery health and lower demand charges.

Smart Parking & Multi-Family AC Networks

Commercial AC solutions with dual 22kW outlets provide reliable, low-maintenance charging. Equipped with smart load sharing and OCPP 1.6J/2.0.1 integrations, these units fit into existing building management systems without triggering costly utility upgrades.

Public Highway Infrastructure

High-reliability dual-gun DC chargers (120kW to 180kW) are designed to withstand varying environmental conditions. Features include IP55 protection, integrated payment terminals, and direct links to charge point operator (CPO) software.

Beihai Power Service Operations & Customer Success

Global Enterprise Sourcing, Grid Integration, and Compliance

Commercial procurement demands compliance with diverse grid codes, electromagnetic compatibility (EMC) regulations, and regional certification requirements. Our hardware complies with standard international criteria, including IEC 61851, CE, and local grid certifications.

Technical Sourcing FAQ

Essential considerations for purchasing managers, electrical contractors, and municipal planning authorities.

What are the main advantages of modular power units in DC fast chargers?

Modular configurations improve overall system reliability. By using multiple independent power modules (such as 30kW or 40kW units) in a single cabinet, the charger remains operational even if one module requires service. This configuration prevents complete system downtime and simplifies maintenance through straightforward component replacement.

How does the system ensure grid stability during peak charging periods?

Our smart chargers feature dynamic load balancing. Using Modbus and OCPP protocols, the stations monitor grid demand in real time. The system automatically adjusts current distribution across all active charging guns, helping operators optimize energy consumption and avoid peak demand penalties.

What standards and connectors are supported for international shipping?

Our charging stations support major global connector types, including CCS1 for North America, CCS2 for Europe, CHAdeMO for Japan, and GB/T for China, as well as Type 2 AC inlets. This configuration flexibility ensures compatibility with diverse electric vehicle fleets worldwide.

Can these chargers operate under extreme temperatures, such as below -30°C or above 50°C?

Yes. Our industrial-grade charging cabinets feature active thermal management, using liquid-cooling or high-efficiency air cooling to control temperatures. We also supply ultra-cryogenic component variations, including solid-state battery configurations and specialized heaters, that remain operational in temperatures as low as -80°C.

What custom OEM and ODM options are available?

We provide full customization, including custom exterior branding, software integration for payment systems, and structural adaptations. Examples of our custom engineering include 150kW vehicle-integrated mobile chargers and containerized high-power split systems.
