[Industry Pain Point Analysis] In the coal‑transportation sector, do 180‑ton class electric heavy‑duty trucks face mid‑trip range‑anxiety? Does their high‑frequency operation—averaging eight round trips per day—drive electricity costs to persistently high levels? And does grid instability directly undermine transport efficiency?

On Mongolia’s 70-kilometer coal‑transport dedicated route, Guangzhou Ruisu Intelligent Technology’s integrated solar‑storage‑charging solution enables 20 electric heavy‑duty trucks to operate with “zero range anxiety and low‑cost operation,” effectively addressing the operational bottlenecks facing the new‑energy heavy‑truck sector.

Core Performance Metrics: Quantitative Presentation of Solution Value

Power supply capacity:

• It delivers a steady 64,000 kWh of electricity per day, sufficient to meet the battery‑swap needs of 20 electric heavy‑duty trucks making eight round trips daily, with a single swap providing 400 kWh—precisely aligned with the range requirements of such trucks.

Photovoltaic Efficiency:

• The system is equipped with a 19.8 MWp high-efficiency photovoltaic array, boasting a service life of up to 25 years, and achieves efficient conversion and utilization of solar energy across a 130,000 m² site.

Energy storage assurance

• The total energy storage capacity reaches 7.2 MWh, comprising a 3.6 MWh stationary storage unit and a 3.6 MWh mobile storage unit, enabling uninterrupted energy supply during nighttime and overcast or rainy conditions.

Fast-charging efficiency:

• Two 1.5 MW chargers have been deployed, offering dual functionality—charging both vehicles and energy storage systems—and delivering refueling efficiency three times higher than conventional charging infrastructure.

Full-Chain Advantages: Ruisu Technology’s Intelligent Core Competitiveness

As a company with end-to-end R&D and manufacturing capabilities across the entire value chain of charging and energy storage systems, Ruishu Intelligent Technology’s core competitive advantages lie in its meticulous technical control and rigorous quality assurance at every stage of the solution.

Photovoltaic system

• High-efficiency bifacial half-cell photovoltaic modules are paired with multi-MPPT inverters, boosting power generation by 15% compared to conventional modules. The steel‑structure PCS step-up transformer is coated with a fluorocarbon spray finish, ensuring resilience in extreme climatic conditions.

Energy Storage Core

• Equipped with lithium iron phosphate batteries, it offers high safety and durability, operates reliably in temperatures ranging from –40°C to 60°C, boasts a cycle life exceeding 8,000 cycles, and its 400 kWh battery pack supports plug-and‑swap for rapid maintenance.

Energy replenishment technology

• Mobile energy storage vehicles enable flexible dispatch, effectively addressing the challenge of energy replenishment in remote mining areas and similar settings. The 1.5 MW charger supports a wide DC voltage range of 200–1000 V, making it compatible with a variety of mainstream heavy-duty electric trucks.

Intelligent Operations and Maintenance

• Outdoor switchgear cabinets strictly comply with local industry standards, while the backend system monitors equipment status in real time via Ethernet, WiFi, and 5G multi‑link connectivity, with fault‑alert response times not exceeding 10 minutes. 。

Energy Management Strategy: Achieving Full-Cycle Cost Optimization

The Ruisu Technology solar‑storage‑charging system is equipped with an intelligent energy management module that maximizes energy utilization efficiency through optimized scheduling. Its core strategies include:

1. Photovoltaic Priority Dispatch: During the day, photovoltaic power generation is prioritized to directly meet the battery‑swapping demand of electric heavy‑duty trucks, with any surplus electricity stored in energy storage units, thereby achieving full utilization of solar resources.
2. Energy storage for peak‑shaving and load‑balancing: As photovoltaic generation declines in the evening, a combined power‑supply mode involving stationary energy storage and mobile energy‑storage vehicles is activated, thereby avoiding high‑demand‑period electricity tariffs and reducing electricity costs.
3. Multi‑layered emergency backup: In the event of extreme weather or grid failures, the system automatically switches to an independent energy‑storage‑based power supply mode, ensuring that the 180‑ton class electric heavy‑duty truck can complete its daily eight‑trip transport schedule without interruption.
