Can electric excavators even “order takeout” for their power supply? The Ruisu mobile energy storage unit is available on demand, with electricity following the machine—highly efficient!

As the “dual carbon” goals take shape, the Ministry of Housing and Urban–Rural Development and the National Development and Reform Commission are jointly promoting green and low‑carbon construction. An increasing number of construction sites are making electric equipment a mandatory requirement in their bidding processes, and construction sites once dominated by the roar of diesel generators are gradually being replaced by quiet, environmentally friendly electric excavators. However, the ensuing challenges in power supply have become a new headache for project managers: remote construction sites suffer from inadequate grid coverage, fixed charging stations lack mobility, and lengthy recharging times hinder construction progress. So, are electric excavators left only to “gaze longingly at electricity”?

The answer, of course, is no! Today, electric excavators on construction sites have long since moved beyond their reliance on fixed power sources. Ruisu Intelligent 6000V High-Voltage Mobile Energy Storage Vehicle ， Just like “Charging Delivery” Similarly, it’s available on demand—electricity follows the machine wherever it goes—completely resolving the pain point of power supply for electric excavators. Backed by real‑world field test data, it demonstrates with concrete results what truly means… “Efficient energy replenishment, uninterrupted construction.”

Recently, we have been... Gansu Jiuquan construction site Launched a Real-world power supply testing ， The Ruisu 2.7 MWh/6000 V high-voltage mobile energy storage vehicle is for on-site use. SANY electric excavator Providing uninterrupted power throughout the entire process, the measured data left the audience in awe. Using sheer performance to shatter the stereotype that electric excavators suffer from slow charging and unstable power supply.

This test was conducted under real-world construction-site conditions throughout, and the final measured results are as follows: With continuous power supply for 4 hours, total energy consumption amounted to 566 kWh, enabling the electric excavator to load 45 cubic meters of earth and rock per truck, for a cumulative total of 30 trucks loaded.

What appears to be a simple set of figures actually conceals the core advantages of a 6,000-volt high-voltage platform. It’s worth noting that, Large electric excavators are high-voltage, heavy-duty equipment that place extremely stringent demands on the stability and continuity of the power supply. ， Traditional diesel generators are not only noisy and heavily polluting, but also have high per‑kilowatt‑hour costs and are prone to breakdowns that cause downtime. Meanwhile, stationary charging stations are constrained by site availability and cannot be relocated to match the excavator’s work locations; when the machine requires long‑distance recharging, construction schedules inevitably suffer.

Meanwhile, the Ruisu high-voltage mobile energy storage vehicle, Equipped with a native 6kV high-voltage platform , eliminating the need for on-site installation of a step-up transformer, it can directly supply power to high-voltage electric excavators, with no voltage drop or power interruptions throughout operation, and can sustain continuous heavy‑load work for 4 hours without any loss of performance.

Based on the efficiency measured in this test, a single day can help a large electric excavator complete nearly… 200 truckloads of earthwork and rockwork operations , compared with traditional power supply methods, Construction efficiency improved by more than 30% ， At the same time, it achieves zero emissions and low noise levels, fully meeting green construction standards.

With the advancement of electric excavator technology, mainstream brands have successively launched high-voltage‑platform large‑capacity electric excavators, while the Ruisu 6000V high‑voltage mobile energy storage unit features a high‑voltage platform, Its core function is to output high-voltage electrical energy. , specifically tailored to meet the power requirements of this type of high-voltage electric excavator.
