Engineered to operate seamlessly in northern Mongolia's sub-zero continental temperatures (down to -40°C), supporting heavy mining fleets, public transit, and commercial depots.
Analyzing the Commercial, Mining, and Infrastructure Dynamics of Heavy-Duty EV Adoption in Northern Mongolia
Erdenet, as the second-largest city in Mongolia and the capital of Orkhon Province, serves as the economic powerhouse of the nation's heavy industry, driven primarily by the Erdenet Mining Corporation (EMC)—one of the largest copper and molybdenum ore mining and processing complexes in the world. As global commodity markets demand decarbonization across mineral supply chains, Erdenet is facing a transformative shift toward fleet electrification.
Transitioning heavy haulage trucks, logistics transport, public transit fleets, and municipal utility vehicles from diesel to electric powertrains requires high-capacity direct current (DC) fast-charging infrastructure. However, the local grid infrastructure and extreme Siberian-influenced climate present unique challenges that standard charging hardware cannot overcome.
Erdenet experiences extreme sub-arctic climate variations, with winter temperatures plummeting below -35°C to -40°C and summer peaks reaching over 30°C. Standard commercial EV chargers suffer severe efficiency loss, cable stiffening, screen freezing, and component degradation under such conditions.
Delivering robust power infrastructure with proven reliability across extreme global operating environments
How Modern High-Power Charging (HPC) & Photovoltaic Energy Storage Systems redefine Commercial Mobility
As commercial electric trucks and heavy mining machinery adopt 800V and 1000V battery architectures, charging demands have escalated from conventional 50kW units to high-power 180kW, 360kW, and 720kW split-unit supercharging stacks. Ultra-fast charging minimizes fleet downtime, enabling 200km to 300km of range replenishment in under 10–15 minutes.
Modern commercial infrastructure requires open protocol backends. With OCPP 1.6J and 2.0J compliance, charging operators in Erdenet can integrate seamless central management software, execute real-time load management, conduct dynamic pricing, and deploy "Plug & Charge" capabilities via ISO 15118 PKI certificate handling.
To overcome local grid constraints in remote mining regions of Orkhon Province, integrated PV-Storage-EV Charging hubs aggregate rooftop solar arrays, modular LiFePO4 battery storage, and smart DC fast chargers. This microgrid architecture buffers the grid from peak load spikes and drastically cuts electricity costs.

Customized Charging Topologies Built for Severe Northern Mongolian Climate & Heavy Mining Transport
Heavy duty electric haul trucks and site service pickups operating around copper mining sites require ultra-fast, robust charging. Tongxing’s 240kW to 360kW DC Fast Chargers feature dual-gun CCS2/GBT connections with IP65-rated dust and moisture protection, safeguarding delicate power electronics against fine copper dust and heavy outdoor blizzards.
Positioned along the key Ulaanbaatar-Darkhan-Erdenet highway artery, commercial transit hubs require rapid turnaround. Our split-cabinet 480kW supercharging stacks automatically allocate power between guns depending on real-time state of charge (SoC), ensuring long-distance transport fleets can top up within 15 minutes.
Urban parking spaces, commercial shopping centers, and municipal offices in Erdenet benefit from 60kW to 120kW wall-mounted or floor-standing DC chargers equipped with 7-inch to 12-inch anti-glare touchscreens, integrated RFID reader modules, and localized billing gateway support.
For remote mineral exploration sites distant from the main grid, containerized off-grid charging stations combine solar arrays, high-voltage battery storage, and 30kW–60kW mobile DC fast chargers. Units provide 72 hours of uninterrupted autonomous operation even during low-sunlight winter conditions.
