Against the backdrop of the global strategic shift toward green industrial transformation, electric construction machinery—boasting zero emissions and low noise as key advantages—is gradually replacing traditional fuel‑powered equipment and emerging as the industry’s mainstream. However, challenges such as inadequate charging infrastructure and inefficient on‑site energy‑replenishment continue to hinder the large‑scale deployment and adoption of electric excavators. Recently, Ruisu Intelligent Technology successfully completed a field demonstration in Nanning, Guangxi, integrating its 1.7 MWh mobile energy‑storage‑and‑charging vehicle with XCMG’s 70‑ton class electric excavator. This trial not only validated the technical feasibility of the “mobile storage‑and‑charging vehicle + electric excavator” collaborative operation model but also effectively addressed the challenge of sustaining continuous operations at construction sites lacking fixed power‑supply facilities, setting a replicable and scalable benchmark for innovating energy‑replenishment systems in the new‑energy construction‑machinery sector.
Field test results: A real-world demonstration of coordinated energy replenishment in a non‑infrastructure setting.
This experiment takes a complex construction site without fixed charging infrastructure as its simulation target and employs “ XCMG 70-ton class A coordinated solution integrating an electric excavator with the Ruisu 1.7 MWh mobile energy storage and charging vehicle has been implemented to systematically verify the stability of their integrated operation and the efficiency of energy replenishment. During testing, the Ruisu mobile energy storage and charging vehicle first completes energy‑storage recharging at a fast‑charging station near the construction site, then precisely transports the stored energy to the work area to provide direct power to the electric excavator. This approach enables frequent, precision‑controlled energy‑replenishment operations tailored to the construction schedule and operational duration requirements.
During the testing phase, the technical team, in conjunction with real-world operational conditions, simulated various daily operating‑time requirements and conducted multiple cyclic energy‑replenishment tests. Test data indicate that the Ruishu mobile charging and storage vehicle and… XCMG’s hundred-ton class The electric excavator achieves seamless end-to-end integration, reliably supporting continuous operation even in the absence of fixed charging infrastructure. Meanwhile, leveraging Ruisu Intelligent’s independently developed energy management system, the test team has successfully formulated an optimal charging strategy that not only meets the high‑power demands of the electric excavator but also ensures efficient energy allocation, effectively alleviating range‑anxiety on construction sites and enabling earthmoving operations to proceed efficiently, low‑carbon, and smoothly. The core data gathered from this field trial provides critical technical support for XCMG to expand its market channels for electric construction machinery and optimize its operational strategies.
Core Advantages of the Ruisu 1.7 MWh Mobile Energy Storage and Charging Vehicle
The Ruisu 1.7 MWh mobile charging and energy‑storage vehicle can precisely meet the energy‑replenishment needs of 70‑ton or 100‑ton class electric excavators, thanks to its integrated energy‑supply system that features “large capacity, high flexibility, intelligent management, and low energy consumption.” Specifically, it offers four key advantages:
1. High capacity and high voltage work in tandem to meet the demands of sustained, high‑power supply.
This equipment is equipped with a 1.7 MWh high-capacity energy storage system and an 800 kW high-voltage output module. Compared with conventional mobile charging‑and‑storage units, its storage capacity is increased by more than 40%, fully meeting the high-voltage power demands of hundred‑ton class electric excavators. After a single full charge, it can support multiple machines in continuous operation for several hours, significantly reducing refueling frequency and markedly improving construction efficiency. The core architecture of the device is divided into two major modules: a DC compartment and an AC compartment. The DC compartment houses a high‑capacity battery pack, providing a robust foundation for energy storage, while the AC compartment integrates a bidirectional PCS converter, a transformer, and an EMS control system, enabling efficient energy conversion and intelligent management.
2. Three-in-one mobile functionality delivers a one-stop power supply solution.
Unlike single-function power‑supply equipment, the Ruisu Mobile Power Storage and Charging Vehicle integrates three core capabilities—mobile power delivery, mobile power supply, and mobile power consumption. It can be flexibly positioned alongside operating equipment to provide targeted power; during equipment operation, it delivers continuous power via its onboard system; and it also supports auxiliary power needs such as site lighting and small tools. This truly enables “one vehicle, multiple uses,” significantly streamlining on‑site power‑supply workflows and reducing operational management costs.
3. A sophisticated intelligent control system has been refined, ensuring a dual enhancement of safety and efficiency.
The equipment is equipped with an intelligent monitoring system and a battery management system independently developed by Ruishu, enabling real-time acquisition and analysis of critical operating parameters such as state of charge, voltage, and current, thereby effectively mitigating damage to operational equipment caused by voltage fluctuations. It supports remote dispatch and management, with the backend system providing real-time tracking of equipment location and operational status to ensure precise alignment with energy‑replenishment needs. Additionally, it features a battery health‑status early‑warning mechanism that proactively assesses battery life and potential failure risks, reducing the likelihood of equipment downtime and ensuring the seamless continuation of construction operations.
4. Significant energy savings, reducing long-term operating costs.
On the one hand, the equipment supports a peak‑valley time‑of‑use energy storage model, enabling energy to be stored during low‑price periods and discharged to power operational equipment during high‑price periods. Calculations indicate this can reduce a company’s annual electricity costs by 15%–20%. On the other hand, advanced battery cycling technology extends the battery’s service life to over eight years—30% longer than the industry average—thereby significantly reducing the frequency of equipment replacements and helping achieve lifecycle‑wide cost control and energy‑saving, consumption‑reduction objectives.
Scenario Application Expansion: All-Scenario, All-Terrain Adaptability
The Ruisu 1.7 MWh mobile energy storage and charging vehicle is not only compatible with… XCMG 70-ton class The electric excavator can be widely deployed across various high‑power, new‑energy applications, including heavy-duty new‑energy trucks, mining dump trucks, and port quay‑crane equipment. Moreover, this machine boasts exceptional environmental adaptability and outstanding off‑road performance, truly delivering on the goal of “usable in all scenarios and capable of reaching any terrain.”
In terms of extreme‑climate adaptability, leveraging a wide‑temperature‑range battery‑management system that operates from –30°C to 60°C, this equipment can maintain stable operation in harsh environments—such as desert mining sites with summer surface temperatures reaching 55°C or northeastern construction sites in winter at –25°C—while keeping power‑output fluctuations within 5%. Regarding resilience in complex settings, the unit boasts an IP65‑rated enclosure and a sealed charging interface, delivering excellent dust‑ and water‑proof performance. Paired with an electromagnetic‑interference‑resistant system, it ensures reliable power delivery even in high‑voltage grid areas and regions with dense wireless signals, with an annual failure rate below 0.5%. As for all‑terrain mobility, the device is equipped with a 4×4 all‑wheel‑drive system and off‑road tires with superior traction, enabling a gradeability of up to 30° and a minimum turning radius of just 6 meters. This allows it to navigate steep mine slopes, construction pits, and makeshift field access roads with ease, effectively addressing the longstanding challenges of conventional mobile energy‑storage and charging units—namely, their inability to reach or operate in such demanding conditions.
