How iCube Works




Traditional power sources: diesel generators


Game changing solution with iCube series

Where to use energy storage


- Passenger/Material Hoists -Tower Cranes

- Welders

- Desanders

- Barbenders

*Suited for equipment with intermittent load but high current requirement characteristic.


The construction sector is a major contributor to global energy-related carbon emissions, with construction processes alone responsible for 11%. Decarbonizing this sector is crucial for carbon neutrality. Battery energy storage systems (BESS) offer a sustainable alternative to diesel-fueled equipment, reducing emissions by up to 85%.

Rapidly Charge Electric Vehicles on Sites with Limited Power

Charge electric vehicles (EVs) or mobile machinery directly on-site.

sdtr (1)

●  Facilitate broader adoption of EVs.

●  Enable quick charging for trucks and fleet vehicles at construction sites.

Power Distant Plants Away from Grid Connections

Charge large mobile batteries overnight and transport them to the plant during the day to support electrified construction.

sdtr (2)

●  Promote wider adoption of EVs and battery- powered mobile machinery.

●  Eliminate the need for extensive cabling materials and installation.

●  Avoid using generators to charge equipment at the plant.

Supply Power to Small Tools and Equipment for Low-Power Projects (e.g., Rail Maintenance)

Deploy fully mobile, small batteries that can be relocated to the site to power tools throughout the day.

sdtr (3)

●  Eliminate the use of small diesel generators.

● Reduce noise and air pollution in environmentally sensitive areas.

● Operate batteries safely in enclosed environments like tunnels.
