China Portable Car EV Charger Manufacturer & Factory

Industrial-Grade Mobile Charging Stations, Advanced V2L/V2H Discharge Platforms, and Integrated DC Fast Charging Solutions engineered for global energy transition.

Precision Power Engineering & OEM EVSE Manufacturing

Beihai Power (China Beihai Power Co., Ltd.) is a specialized manufacturer dedicated to the innovation of DC fast-charging technology and smart AC charging systems. We successfully bridge the gap between complex municipal utility capabilities and reliable commercial charging infrastructure. Our footprint spans across Central Asia, Southeast Asia, the Middle East, Europe, Africa, South America, and North America.

Our core engineering mission addresses three critical challenges of electric vehicle charging: charging efficiency, thermal safety management, and grid integration stability. By designing and manufacturing our own high-efficiency integrated power control modules, we deliver advanced power systems that assure rapid, safe, and continuous energy transfer under extreme operations.

Global Fleet Electrification & Micro-Grid Integration

Addressing macro-level bottlenecks: grid overload, operational downtime, and remote deployment limits.

Grid Load Balancing & Smart Peak Shaving

With smart AC and DC fast chargers utilizing OCPP 1.6J / 2.0.1 protocols, we enable peak shaving solutions. Our power systems dynamically throttle outputs based on real-time grid feedback, safeguarding industrial plants and site circuits from high energy surcharges.

Vehicle-to-Everything (V2X) and Bidirectional Power

Our V2L and V2H technologies deliver off-grid energy stability. By enabling a continuous 7.5kW discharge from electric vehicle batteries to remote machinery, we empower disaster response, military field applications, and off-grid construction sites.

Severe-Climate Resilient Design

Engineered for high thermal tolerance, our cabinets and internal modules operate seamlessly in ambient temperatures from -30°C in Central Asia to over 55°C in Middle Eastern deserts, utilizing dynamic air-cooling or liquid-cooling manifolds.

Technological Roadmap & Next-Generation Energy

We are pushing past current limits by integrating solid-state cell architecture and extreme low-temperature resilience.

Solid-State Pouch Cell Integration

Leveraging our 13Ah solid-state lithium-ion battery technology, our engineering department is pioneering lightweight mobile storage units. These offer up to 40% higher volumetric energy density compared to traditional cylindrical packs.

Extreme Temperature (-80°C) Engineering

Our ultra-cryogenic cell design operates in the absolute coldest climates. This prevents thermal slowdowns in Arctic transport networks, commercial cargo drones, and military VTOL aircraft operating at high elevations.

Liquid-Cooled Modular Cables

Future high-power units will feature ultra-lightweight liquid-cooled cables. This will enable safe, high-current transfer (up to 500A) without increasing gun weight or cord thickness, making it easier for commercial operators to handle.

Technical Deep-Dive & FAQ

Addressing crucial engineering, regulatory, and mechanical questions for EV charging infrastructure procurement.

What is the efficiency profile of Beihai Power high-frequency switching modules?
Our proprietary AC/DC power modules utilize advanced SiC (Silicon Carbide) MOSFETs, enabling up to 96% overall energy efficiency during peak load. This high conversion rate directly translates to minimal thermal dissipation, lowering cooling system energy consumption and boosting overall charging station lifespans.
How does the V2L/V2H 7.5kW discharge station manage output voltage and safety parameters?
Our 7.5kW portable outbound discharge unit features isolation transformers and automatic phase alignment. It converts high-voltage DC output from vehicle batteries to stable grid-grade 220V/110V AC, protecting home appliances and commercial field equipment with fast-acting short-circuit, overcurrent, and leakage protection.
Does your hardware support smart integration with custom charge point operator (CPO) software?
Yes. All commercial DC fast chargers (60kW up to 240kW/480kW) come pre-programmed with OCPP 1.6J. They are fully compatible with OCPP 2.0.1 integrations, allowing CPOs to easily configure user authorization, payment processing, remote diagnostic systems, and dynamic grid power allocations.
How does the solid-state cryogenic battery maintain performance down to -80°C?
Our 13Ah solid-state pouch cells use an advanced solid inorganic electrolyte instead of liquid or gel options. This prevents electrolyte freezing and dendrite formation under extreme cold, maintaining steady ion conductivity and stable safety profiles for extreme high-altitude drone and cargo missions.
What safety mechanisms are built into the cabinet design?
Our cabinets features multiple levels of safety integration: built-in surge protection (Type 2 SPD), active leakage detection, ground fault protection, over-temperature throttling, mechanical emergency shutdown controls, and smart electronic locking cables to prevent disconnection while current is flowing.
