As the “dual carbon” goals gain momentum and urban construction environmental regulations are comprehensively tightened, the electrification of construction machinery has evolved from an industry trend into a mandatory requirement. As a core piece of equipment for pile‑foundation work, the electrification of rotary drilling rigs is accelerating: as of May 2026, the market has introduced 21 electric rotary drilling rig models, covering the mainstream power range of 130–300 kW, with technical capabilities steadily maturing. However, persistent challenges—such as difficulties in connecting to fixed grid power and inconvenient on‑site power supply—are now emerging as the “last mile” bottleneck hindering the widespread adoption of electric rotary drilling rigs.

As a full‑chain manufacturer of charging and energy‑storage equipment, Ruishu Intelligent Technology has leveraged its core technological strengths to develop a high‑capacity, high‑rate mobile charge‑and‑store vehicle solution. This breakthrough effectively resolves the power‑supply bottleneck of electric rotary drilling rigs, offering an optimal, all‑scenario, high‑efficiency, and cost‑effective solution for advancing the electrification of construction machinery.

Electric rotary drilling rig case: Electric‑powered cost reductions deliver impressive results, yet the equipment remains constrained by reliance on fixed grid power.

At a construction site in the core area of a city in Shandong Province, two Yutong‑branded electric rotary drilling rigs (YTR306HE and YTR266HES) were deployed, powered by a conventional overhead‑line system. Operating steadily for six hours per day over a one‑month construction period, measured data unequivocally demonstrated the tangible benefits of electrification:

1. Environmental Protection Side : Fully electric‑driven with zero tailpipe emissions and noise levels that meet regulatory standards, it perfectly complies with Chengdu’s stringent urban construction environmental regulations, resulting in zero instances of environmentally‑related work stoppages.

2. Cost side: The electric model incurs daily electricity costs of just RMB 675, saving over RMB 2,000 per day compared to the diesel model; over 20 days, each drilling rig accumulates energy cost savings of RMB 43,000.

3. Break-even analysis: The purchase price of an electric rotary drilling rig is 20% higher than that of a diesel‑powered model; under continuous, stable operating conditions, the premium can be recouped in as little as six months.

Key shortcomings: This project could only be implemented by leveraging the mature municipal power grid in the urban area. If the project were relocated to an undeveloped plot on the suburban fringe or to a remote mountainous region lacking a reliable grid connection, the overhead‑line‑based power supply solution would become unfeasible, and its cost‑effectiveness would be impossible to realize.

Ruisu Mobile Power‑Storage Vehicle: A comprehensive, all‑scenario power supply solution tailored for electric rotary drilling rigs.

Addressing the power‑supply challenges of electric rotary drilling rigs, Ruisu Intelligence leverages its comprehensive technological expertise across the charging and energy‑storage value chain. Its 431 kWh–3,450 kWh series of high‑power mobile charge‑and‑store vehicles seamlessly meets the power requirements of mainstream electric rotary drilling rigs rated at 130–300 kW.

1. Plug-and-play, no fixed power grid required.

The mobile charging and storage vehicle is equipped with a high-capacity lithium‑iron‑phosphate battery pack, enabling it to directly power electric rotary drilling rigs without requiring prior grid‑connection approval—simply arrive on site and begin operations.

2. High-power fast charging, designed for continuous operation.

Equipped with Ruisu’s proprietary liquid-cooled ultra‑fast charging technology, the system delivers a maximum single‑gun output of 300 kW and can simultaneously power 4 to 6 electric rotary drilling rigs, each rated at 300 kW. The 2,156 kWh‑capacity model enables a single 300 kW rotary drill rig to operate continuously for more than six hours, fully meeting daily construction requirements.

3. Multi-vehicle cooperative power supply

It supports parallel networking of multiple charging and storage units, meeting the high-power requirements of several electric rotary drilling rigs operating simultaneously, and is well-suited for large-scale pile foundation projects.

4. Intelligent Energy Management

Equipped with Ruisu’s proprietary EMS energy management system, it can monitor equipment power consumption in real time, dynamically allocate power, and optimize energy efficiency. It also supports peak‑valley electricity price arbitrage: charging during low‑price periods and discharging during high‑price periods, further reducing costs.

5. Rapid transitions, flexible deployment

Featuring a vehicle-mounted design, it can be swiftly relocated to different job sites alongside the electric rotary drilling rig, eliminating the need for re‑wiring and significantly enhancing construction flexibility.

The Four Core Advantages of the Ruishu Smart Mobile Charging and Storage Vehicle

1. Full-scenario coverage, breaking through construction‑site geographic constraints.

Completely eliminating reliance on the fixed power grid, whether in urban core areas, remote mountainous regions, on highways, or at railway construction sites, mobile energy storage and charging vehicles can deliver reliable power whenever needed, enabling electric rotary drilling rigs to truly go wherever they’re required.

2. Ultimate cost reduction: energy costs cut by another 15%–20%

In addition to the electric rotary drilling rig’s inherent energy‑cost advantages, the mobile charging‑storage vehicle can also exploit the peak‑valley electricity price differential for arbitrage. By fully charging during off‑peak nighttime hours—at around RMB 0.3 per kWh—and discharging during daytime operations, energy costs can be further reduced by 15%–20% compared with directly using grid‑peak rates of approximately RMB 1.2 per kWh, thereby shortening the investment payback period even further.

3. End-to-end quality across the entire industry chain, with guaranteed safety and reliability.

The core components—PCS, BMS, and EMS—are all independently developed and manufactured, ensuring product quality from the source. The products have passed national mandatory certification and feature multiple protection functions, including overcharge, overdischarge, overheating, and short-circuit protection, while also being equipped with an intelligent fire‑safety system to guarantee electrical safety on construction sites.

4. Intelligent operations and maintenance to enhance equipment management efficiency.

Equipped with the Ruisu Intelligent Cloud Platform, it enables real-time monitoring of charging‑station operations, battery health, and energy consumption data, while supporting remote fault diagnosis and early warning. In addition, comprehensive lifecycle maintenance services are provided to ensure long-term, stable equipment performance and reduce customers’ operational costs.

Backed by the strength of the entire industry chain, we are jointly building a new ecosystem for the energy transition.

Electrification in the construction machinery sector is an irreversible industry trend, and innovation in power‑supply solutions is key to driving this shift. The mobile battery‑storage‑and‑charging vehicle solution developed by Ruisu Intelligent Technology not only fully addresses the power‑supply challenges of electric rotary drilling rigs but also sets a replicable, scalable benchmark for the electrification transformation of the entire construction‑machinery industry.

Looking ahead, Ruisu Intelligence will continue to deepen its expertise in the new‑energy charging and energy‑storage sectors, consistently introducing products and solutions that are more efficient, smarter, and better aligned with industry needs. Together with construction professionals, we will co‑create a new era of green, low‑carbon, and highly efficient construction.
