FlexCube EL-EU

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.
