In 2025, Heavy-duty electric construction machinery is undergoing a qualitative shift from “policy-driven” to “value-driven.” . Leading equipment manufacturers such as SANY, LiuGong, Lingong, and XCMG, High-voltage electric excavators, electric mining trucks, and other heavy-duty construction machinery have been rolled out for mass deployment. 。
However, an awkward reality is spreading across construction sites: I bought the car, but the battery’s dead.
This is not a matter of “charging convenience”; rather, it is the critical bottleneck determining whether high-voltage, heavy-duty electrification can truly be implemented.
Ruisu Intelligence believes: Only when “electricity” becomes as convenient as diesel—available on demand, with high‑volume refueling and low costs—can electric construction equipment fully replace its fuel‑powered counterparts.
Accordingly, the 2.59 MWh/6000 V mobile energy storage vehicle was developed.
Ruisu Intelligence’s solution is, at its core, a “mobile high-voltage distribution substation.”
The entire vehicle is packaged in a standard 20-foot container (6058×2440×2900 mm) and features integrated internal components:
✅️2.59 MWh high-safety lithium iron phosphate battery system
✅️1500 kW power output
✅️1500 kVA/6000 V step-up transformer (dry-type)
✅️ Tier-3 BMS battery management + dual fire protection system
✅️IP65 battery module / IP54 full-cabinet protection
⭐ DC side
1500V high-voltage direct supply, designed specifically for heavy-duty applications.
Compatible with mainstream 1500V high-voltage platform electric excavators.
⭐ AC side
Covering all‑scenario electric construction machinery,
Through the built-in 1500 kVA dry-type step-up transformer
Achieve a 6000V AC output, It provides native high-voltage power to 6,000 V‑class electric mining trucks and heavy-duty electric excavators, eliminating the need for external step-up equipment.
The Ruisu 2.59 MWh mobile energy storage vehicle can power all vehicle types from a single unit.
In grid‑blind spots, the Ruisu mobile energy storage vehicle is the only solution that can simultaneously meet “High Power + Zero Emissions + Flexible Relocation” A feasible solution.
Moreover, by storing electricity during off-peak nighttime rates and discharging it during the day, the cost per kilowatt-hour can be further reduced to below RMB 1.0, making it approximately 70% cheaper than diesel-generated power.
The 2.59 MWh mobile energy storage vehicle faces conditions on construction sites that are far from laboratory settings—namely, sand and dust, severe vibrations, extreme high and low temperatures, and continuous heavy‑load impacts. At the engineering level, Ruisu has implemented a three‑tiered, targeted design:
In a nutshell: It can handle any road a mine can access, and it can withstand any operating conditions a excavator can endure.
Just recently, Ruishu Intelligence delivered a 6,000V high-voltage mobile energy storage power vehicle to a large mining site in Jiuquan, Gansu Province, replacing multiple existing diesel generator sets and providing off-grid power to SANY electric excavators.
On a certain day, measured data showed:
After 4 hours of continuous operation, the total energy consumption was 566 kWh.
The earthwork and rock excavation loading was successfully completed, with a total of 30 truckloads, each carrying 45 cubic meters.
Energy consumption costs have decreased by 58% compared to diesel.
Equipment availability has increased to 96% (previously, diesel-powered systems experienced a high failure rate).
This case demonstrates that, under extreme field conditions, mobile energy storage units can fully replace diesel generators, offering high voltage with low losses and superior economic efficiency.
The Ruisu mobile energy storage vehicle is not designed for a single model; rather, it is a… The All-Powerful “Mobile Energy Storage Power Station” . Currently supported:
Are you troubled by the following issues:
❌ The construction site is far from the power grid, and the cost of extending power lines far exceeds the cost of the equipment itself.
❌ Diesel generators have high fuel consumption, carry a significant risk of fines, and are not environmentally friendly.
❌ I bought an electric excavator, but it’s been sidelined and sitting idle due to difficulties in recharging.
❌ With multiple projects transitioning between sites, each construction site must re-establish its power supply.
