High-efficiency, dust-proofed and liquid-cooled solutions customized for high-utilization fleet depots and municipal integration in Kaédi.
As the administrative heart of the Gorgol Region and a pivotal hub along the Senegal River basin, Kaédi, Mauritania, presents a unique frontier for heavy transport electrification. Transitioning to electric commercial vehicles, cross-border freight, and municipal bus routes requires an charging infrastructure capable of withstanding extreme environmental constraints. The Sahelian climate presents severe operational challenges for standard EVSE components, including ambient temperatures frequently exceeding 45°C, high concentrations of airborne particulate dust, and seasonal humidity spikes.
Beihai Power addresses these demanding parameters. Our industrial-grade EV charging connectors and cables are engineered to deliver sustained power transfer under high thermal stress. By implementing advanced polyurethane (TPU) sheathing, silver-plated copper-alloy terminal contacts, and rigorously certified sealing structures (rating up to IP67), our connector systems maintain low contact resistance. This mitigates critical overheating risks at sites like the Kaédi regional transport hubs and remote solar-hybrid microgrids.
Our connectors are rated for continuous operation from -30°C up to +50°C ambient temperatures, incorporating localized temperature monitoring systems to ensure safe charging currents.
Complete defense against fine sand and dust intrusion, preventing contact wear, electrical arcing, and hardware degradation at rural charging hubs.
Precision silver-plated pins minimize energy loss at the interface, keeping temperature rise (ΔT) within strict international standard limits under 50K.
Commercial fleet operators and infrastructure developers require robust components that reduce overall cost of ownership. The physical design of an EV charging connector must balance ergonomic handling with mechanical durability, chemical resistance, and electrical safety. Below is a detailed look at the engineering innovations that set Beihai Power apart:
The connector housings are manufactured from high-impact resistant, flame-retardant thermoplastics (UL 94 V-0 rated). This material remains structurally stable when exposed to prolonged UV radiation and intense direct sunlight, preventing cracking, fading, and degradation. Cable jackets are composed of highly flexible, ozone-resistant Polyurethane (TPU), providing excellent wear and abrasion resistance against rough ground conditions.
For ultra-fast DC charging configurations (360kW and above), thermal control is critical. Our 500A CCS1 and 400A CCS2 liquid-cooled connector systems feature built-in coolant channels that circulate synthetic oil or water-glycol mixtures directly past the terminal pins. This allows for lighter, more flexible cables that can support high-current deliveries without overheating.
Our EVSE interfaces include internal resistive temperature sensors (PT1000/NTC) on both the DC+ and DC- terminals. These sensors transmit real-time temperature telemetry to the host EVSE controller, prompting automatic current throttling if safety thresholds are breached. This safety loop protects the charging station, connector cable, and vehicle battery management system (BMS).

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.
Our core mission is to solve the critical challenges of charging speed, system reliability, and grid integration. 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.
Industry-Leading Product Portfolio: We deliver a comprehensive range of DC fast-charging piles, from high-capacity 480KW units to compact commercial charging stations (20, 30, 40KW). Our hardware is engineered for durability and high-utilization environments, including government-led EV infrastructure and public charging networks.
Scalable Manufacturing Excellence: With the capacity to fulfill bulk orders—such as our recent export shipment of 24 custom-configured DC fast-charging piles to Uzbekistan—we combine industrial-scale manufacturing with stringent quality control. Our production capability allows for rapid turnaround, including sample batch fulfillment for international export.
We do not offer "one-size-fits-all" solutions. We specialize in engineering adaptations, such as our 150kW Mobile DC Fast-Charging Solution integrated into commercial vans, developed specifically to meet the unique grid and environmental requirements of our clients in Colombia and the USA.
Our production facilities utilize modern assembly lines, automated component placement, and environmental simulation chambers to verify product performance in harsh conditions before shipment.
High-precision laser cutting of sheet metal structures ensures tight tolerances for all weather-resistant EVSE enclosures.
Automated bending and welding processes form durable, anti-corrosive outer shells rated for coastal and desert environments.
Integration of modular charging compartments, including ventilation paths, filters, and safety shut-off systems.
Comprehensive dielectric testing and inspection verify cabinet grounding, wire insulation, and environmental seals.
Assembly and testing of the core high-frequency switching power modules that drive DC fast charging.
Wiring of control boards, power modules, communication units (OCPP), and user interfaces.
Full unit functional testing under simulated load conditions ensures reliable system performance.
Final environmental stress testing verifies system performance in extreme temperature and high-humidity chambers.
Inside China Beihai Power's manufacturing center: where precision engineering meets high-volume production capabilities.
We feature dedicated R&D teams and quality control personnel, allowing us to manufacture customized AC and DC charging stations to meet unique client specifications. We provide complete solutions for commercial charging projects, backed by responsive post-sale support. Our quality management system, overseen directly by the General Manager, tracks each product from initial manufacturing to installation and long-term operations.
Building EV charging networks in locations like Mauritania requires a reliable, transparent supply chain. Delivering heavy infrastructure components from our manufacturing facilities to project sites in the Gorgol region relies on organized sea and land logistics pathways. Equipment is typically shipped to the Port of Nouakchott or the Port of Dakar, Senegal, followed by secured overland transport to Kaédi along established highway corridors.
To support localized installations, Beihai Power provides detailed engineering documentation. This includes step-by-step installation guides, electrical schematics, and load calculation formulas to help local engineering teams interface our equipment with regional utility grids or isolated solar mini-grids. All connectors, cables, and charging modules are shipped in rugged, moisture-sealed export packaging to prevent damage during transport and handling.
