Innovative Design

Conventional cylindrical Ni-MH batteries consisting of rolled electrodes

and separators heat up during rapid charges and discharges. These

batteries also have limited scalability due to the energy loss created in

their connections. In addition, their welded structure complicates

recycling procedures.

In the GIGACELL®, cooling fans that send air through the structure

prevent overheating. The bipolar structure minimizes energy loss

between cells and actualizes greater capacity. GIGACELL® is highly

recyclable because of its non-welded structure.

Cooling Fan Powerful and ef�cient cooling enables charging / discharging at high amperages.

Non-welded With no welding processes during its production, disassembly and recycling processes are facilitated.

Fully Sealed The GIGACELL® is fully sealed, needing no mainte-nance.

Bipolar enables GIGACELL®’s high capacity and rapid charging

GIGACELL® modules are composed of individual cells that are connected in series by their cell walls, with the front and rear surfaces becoming positive and negative electrodes, forming the bipolar structure. The thin cell walls provide a large cross-sectional area that minimizes energy loss, which occurs when the cells are connected. Therefore, the large capacities of modules can be accomplished by increasing the number of cells connected in the bipolar structure.

Grid Stabilization

System Image

A four-year joint development was conducted to study the usage of GIGACELL® for supply/demand control when more renewable energy is implemented in the grid. GIGACELL® was installed at a substation near a 10-megawatt PV generation plant.

○Electrical Power Supply/ Demand System with GIGACELL®

Output signalCurrent output data

Charging and discharging will occur when frequency exceeds or becomes lower than the standard frequency of 60 Hz respectively. At high and low SOC levels, the system will prevent over-charging/discharging of the batteries.

Distributed Energy (Gas Turbines & Engines) + GIGACELL®

Distributed Generation/Micro-grid

The Hybrid Power System forms a micro-grid system composed of installed wind turbine generator, PV panel and GIGACELL® batteries. The system controller sends optimal charge/discharge signals to the GIGACELL® through the power conditioner based on the generation data of renewable energies and the building’s power

consumption data and the power conditioner charges/discharges GIGACELL®. Therefore, the system not only stabilizes renewable energies, but also can reduce peak demand, level off power loads and provide emergency power during a blackout.
