Mobile Energy Storage System
Application Scenarios
Open-pit mining operations, large construction sites, emergency rescue projects, and other areas with no grid power or weak grid coverage. These locations are characterized by their distance from fixed power sources.
Ultra-High Energy Density
Two models with ultra-high capacities (2090 kWh and 3135 kWh) are available, supporting the long-term operational needs (approximately 8-10 hours) of medium and large electric construction vehicles. A single charge is sufficient for a full day's work, significantly improving efficiency and reducing operating costs.
Flexible and Fast Charging
The mobile energy storage vehicle supports simultaneous DC fast charging with 2-4 charging guns, with charging times of only 2-3 hours. It also supports AC charging from the mains power supply, offering flexible charging options.
Easy Transport and Plug-and-Play Operation
The standard containerized design enables flexible transportation. The quick-connect design for charging and discharging simplifies the connection process.
Safety Features
Multiple safety mechanisms are in place, including overcharge, over-discharge, overcurrent, and short-circuit protection.
Fire and Explosion Prevention Design: The battery compartment is equipped with a combustible gas detector, as well as thermal and smoke sensors. Should gas concentration exceed a preset threshold, the system automatically activates the ventilation system to expel it. In the event of high gas concentration accompanied by thermal or smoke alarms, the fire suppression system is triggered. The entire compartment is also fitted with water-based firefighting interfaces.
Stable Electrical Insulation: The entire vehicle's electrical system has excellent insulation performance, effectively preventing electrical leakage.
Mobile Energy Storage System
Application Scenarios
Ideal for off-grid or weak-grid areas such as construction sites, mines, islands, fishing villages, grasslands, and deserts lacking reliable grid power. The diesel storage system serves as an independent power supply. When under load, the energy storage system works together with the diesel generator to significantly reduce diesel consumption and improve power supply stability.
Abundant Interfaces
Features a standard 400A single-core PowerLock quick-connect input/output interface for high-power applications and a 125A five-core quick-connect input interface for rapid charging and efficient deployment. Offers a variety of AC output interfaces: AC 380V 63A/32A/16A sockets for powering small construction machinery. Customizable socket options are available.
Proven System Reliability
Dual redundancy with energy storage + diesel. Total battery system capacity of 474/711 kWh (using CATL battery cells). Adapts to complex energy demands.
Flexible Product Transport
Designed to fit a standard 10-foot shipping container for easy transportation. After use at one site, it can be easily transported to the next location for deployment.
Multiple Power Control Modes
The system supports VF, PQ, and VSG modes to meet the power support requirements of complex field operations.
Liquid Cooling
Employs liquid-cooled battery packs. Liquid cooling offers superior temperature uniformity and heat dissipation efficiency compared to air cooling, enabling high-rate operation and extending lifespan. The IP67 rating ensures performance in harsh environments, including high temperatures, humidity, and dust.
Application Scenarios
Areas without grid power or with weak power grids, such as mines, mountainous regions, and construction sites. These areas are characterized by the impracticality or high cost of installing charging stations. Therefore, mobile charging vehicles are a more suitable solution for providing DC fast charging to electric construction vehicles/machinery in the work area.
Strong Economic Advantages
This solution saves on grid construction costs in the work area. The mobile charging vehicle directly provides fast charging to construction vehicles on-site (e.g., in mines), significantly reducing infrastructure investment.
Strong Adaptability
Mobile charging vehicles are available in two battery capacity options: 1306 kWh and 2090 kWh. These options cater to the fast-charging needs of small and medium-sized electric construction vehicles/machinery and medium and large-sized electric construction vehicles/machinery, respectively.
Flexible Product Transport
The containerized design allows for flexible transport. Enables rapid relocation. After use at one site, it can be easily transported to the next location for deployment.
Safety Features
The product is equipped with a 320kW dual-gun integrated charging pile, meeting the DC fast-charging needs (less than 2 hours) of most domestic construction vehicles/machinery.
The product itself supports both AC charging and DC fast charging, offering flexible charging options. For DC fast charging, up to six simultaneous charging guns can be customized.
Mobile Energy storage product
Application Scenarios
Weak power grids or off-grid areas, such as construction sites, highlands, islands, fishing villages, grasslands, and deserts. The diesel-storage system can serve as an independent power supply system, with the diesel generator providing supplementary power.
Adaptable to Impact Load Equipment
FlexCube is compatible with impact load equipment such as water pumps, drilling rigs, lifts, and tower cranes.
Dual Charging Circuits, Simultaneous Charging and Discharging
The dual charging circuit design allows for simultaneous charging and discharging from weak power grids or diesel generators, ensuring stable operation of the microgrid.
Maintenance Bypass Design — No Downtime in Case of Fault
In the event of unexpected situations, it can operate independently without service interruption. No cable removal is required — quick and convenient.
Easy Transport — Ready to Move and Use
The standard 10‑foot container and lightweight design allow for easy transport to different locations for deployment.
Quiet Operation
Peak operating noise is below 75 decibels, suitable for noise-sensitive environments.
Side Cable Outlet — Plug-and‑Play
The cabinet features a side cable outlet design, allowing it to be placed directly on flat ground for use without the need for a prefabricated base.
Multi-Unit Parallel Expansion
Power capacity can be flexibly configured to meet the power demands of various scenarios.
