Efficient Power Supply Solution for Heavy-duty Truck Battery Swap Stations: Miniaturized Double-layer Prefabricated Substation

Driven by the "Dual Carbon" goals, heavy-duty truck battery swap stations, as core infrastructure for new energy transportation, demand higher stability, energy efficiency, and environmental adaptability from power equipment. HAIHONG Electric Co., Ltd., in collaboration with Qiyuan Power, ha

s batch-deployed Miniaturized Double-layer Prefabricated Substations and Miniaturized Double-layer double-transformer Substations across Guangdong Province. These provide battery swap stations with cost-effective, highly reliable, and low-loss power solutions, propelling the industry towards a green, low-carbon future.

Core Technical Advantages

Patented Double-layer Structure, Reducing Initial Investment Cost:
As the pioneer and patent holder of double-layer prefabricated substations, HAIHONG Electric provides efficient solutions for power distribution equipment construction. The Miniaturized Double-layer Prefabricated Substation reduces the footprint by 45% compared to traditional substation equ

ipment (excluding civil works area). Adopting the Miniaturized Double-layer double-transformer Substation directly reduces the footprint by 80% (including civil works area), saving the cost of one entire substation.

Strong Overload Capacity & Significant Energy Savings:
The Miniaturized Double-layer Prefabricated Substation features outstanding heat dissipation. Under natural cooling, transformer heat dissipation efficiency increases by 30-40%, resulting in low operational temperature rise, capability for long-term full-load operation, and low load loss. The product can meet the simultaneous charging demands of all chargers and high-frequency battery swapping operations within the station.

The transformers themselves exhibit low operational losses: no-load loss reduced by 30%, load loss reduced by 5%, and no-load current reduced by 70% (compared to laminated core transformers at the same cost). This further minimizes operational energy consumption for the swap station.

Collaboration Impact
HAIHONG Electric and Qiyuan Power have joined forces to provide comprehensive solutions for heavy-duty truck battery swap station construction, featuring fully automated rapid battery swapping, intelligent interaction, flexible deployment, high safety and reliability, low-carbon energy efficiency, and multi-layer fire protection. Multiple projects have already been completed, covering typical application scenarios such as port logistics, trunk line transportation, and urban infrastructure development.

HAIHONG Electric's 3D Wound Core energy-saving power distribution technology not only reduces the entire lifecycle carbon emissions of swap stations but also promotes the standardized development of new energy heavy-duty truck battery swap stations. This accelerates the "diesel-to-electric" transition in the transportation sector and supports China's leadership in the global green energy revolution.
