2026-01-29

Looking ahead, Ruisu Intelligence will continue to deepen its expertise in energy storage technologies, collaborate with more industry partners to address the challenges of power supply for electric equipment, and jointly build a green, low-carbon future‑oriented ecosystem.

Abstract

Driven by the “dual carbon” goals, an electrification wave is sweeping through the construction machinery sector. Electric excavators, with their advantages of zero emissions, low noise, and reduced operating costs, have become the preferred choice in mining, infrastructure development, and other fields.
However, pain points such as short battery life, slow charging, and unstable power supply have become major obstacles to the widespread adoption of electric excavators.

Hardcore solution
Ruisu megawatt‑class energy storage and charging system, precisely tailored to diverse operating conditions.

Ruisu Intelligence focuses on the real-world operating conditions of electric excavators and has launched two megawatt‑class mobile energy storage and charging systems with different capacities, supporting multiple voltage levels—including 6,000 V high voltage and 1,500 V medium voltage—enabling… “On-demand power supply, efficient energy replenishment” 。

2.59 MWh Mobile Charging and Storage System Solution

Specifically for

High-voltage, high-power

Built as an electric excavator, it is perfectly tailored to meet the high‑intensity operational demands of SANY Heavy Industry’s 6,000V‑class electric excavators.

System Architecture

It adopts a 20-foot container design, integrating 12 battery clusters (including a BMS battery management system), a 1000 kVA/6000 V discharge cabinet, a transformer, air conditioning, fire‑suppression systems, and other auxiliary subsystems. The compact structure facilitates transportation and deployment.
The core battery module boasts an IP68 protection rating, supports an extended operating temperature range of –30°C to 55°C, and employs a dual‑temperature control system—liquid cooling combined with liquid heating—to ensure stable performance even in extreme conditions. It also delivers a cycle life of 6,000 cycles at room temperature, with a service life of up to 10 years.

Core Advantages

High-Power Output: Rated power of 1,000 kW, with an AC output of 6,000 V, meeting the power requirements for continuous operation of large electric excavators.
High‑efficiency charging and discharging: Supports dual AC/DC input charging, with a PCS inverter efficiency of up to 99% and a charge/discharge response time of less than 50 ms, enabling “charge and use immediately.”
Intelligent Safety Assurance: Equipped with a perfluorohexanone fire suppression system and an aerosol-based fire protection solution, it provides multi-layered safeguards to eliminate safety risks; supports multiple communication protocols including CAN, RS‑485, and Ethernet, enabling remote monitoring and dispatch.

4.17 MWh Mobile Energy Storage and Charging System Solution

For 1500V‑class electric excavators from brands such as LiuGong, we have tailored a high‑energy‑density charging and storage solution that balances both range and refueling efficiency.

System Highlights

Ultra‑large capacity: The battery has a rated energy of 4.17 MWh and a total output power of 2,000 kW, supporting simultaneous power supply to multiple electric excavators and easily handling large‑scale construction projects.
Flexible energy replenishment: When the battery is low, it can be fast-charged at a dedicated 10 kV charging station (with a maximum charging power of 2,000 kW), or connected to a national‑standard DC charging pile, reducing reliance on the grid.
Precision Voltage Regulation: The DC/DC converter maintains a stable output voltage of 1500 V, with a regulation accuracy of ±1% and a load‑step response time of less than 0.1 s, ensuring smooth and consistent power delivery to the excavator.

Protection and Adaptation

The container meets IP54 protection standards, operates reliably in environments with humidity levels ranging from 0% to 95%, and is rated for altitudes up to 4,000 meters, effortlessly handling challenging conditions such as plateaus and mining sites.

Diverse Scenarios

Beyond excavators: a versatile energy‑supply expert across all sectors.

The Ruisu Intelligent Mobile Charging and Storage System is not only an “exclusive power bank” for electric excavators, but also, thanks to its mobility and plug-and-play convenience, extends its applications to a wide range of scenarios:

Oil well operations: Provides reliable power for oil well exploration and production equipment, adapts to the operating conditions in remote, off-grid areas of oilfields, and ensures operational efficiency.
Heavy-duty truck energy replenishment: It can serve as a mobile charging station for heavy-duty electric trucks, enabling rapid energy replenishment without waiting and alleviating range anxiety in long-haul logistics operations.
Construction Operations: Powering electric loaders, cranes, and other equipment at construction sites, with flexible deployment that moves alongside the project to reduce on-site electricity costs.
Mobile Green Power Direct Supply: Store clean energy during off-peak periods and supply it directly to equipment during peak demand, helping enterprises meet their “green electricity” targets and reduce carbon emissions.
Temporary Power Supply Assurance: In settings such as trade shows, sporting events, and emergency rescue operations, it enables rapid deployment of power supply systems, replacing conventional diesel generators to deliver silent, zero-emission power.

SANY Heavy Industry 6000V-Class Electric Excavator Project

In response to the demand for “24-hour continuous operation” from high-voltage electric excavators such as those manufactured by SANY Heavy Industry, Ruisu Intelligent’s 6000V system has been successfully integrated. This system can directly supply 6000V high‑voltage power to the excavator, eliminating the need for additional step‑down equipment and enabling uninterrupted tunneling in mining environments, while reducing energy costs by more than 60% compared with fuel‑powered excavators.

Liugong 1500V Electric Excavator Power Supply Project

Liugong and other 1,500V‑class electric excavators are renowned for their compactness and agility, making them widely used in urban infrastructure projects. Ruisu Intelligent’s 1,500V system, with its high‑efficiency voltage regulation and rapid energy‑replenishment capabilities, perfectly meets their operational needs: a 1.5‑hour charge provides enough power for an entire day’s work, while reducing equipment failure rates by 90%.

Designated supplier brand for Zoomlion’s Carnival Customer Festival
