BATTERY VS. ULTRACAPACITOR

Koneika's Ultracapacitors, also called Supercapacitors, Ultracaps or EDLCs, combine the advantages of the electrolytic capacitors (fast charge and discharge, millions of cycles of useful life) with those of batteries (storage capacity or energy storage) but with a power delivery 10-100 times higher.

Their advantages:

• High voltage
• High power density
• Quick response
• Robust design and long useful life
• Assembly in any orientation
• Environmentally friendly
• Support the hard conditions of Start-Stop systems

WHAT IS A KONEIKA ULTRACAPACITOR?

They are passive energy storage devices that are characterised by:

• High stored power density.
• Fast energy charge and discharge.
• Easily monitorable charge value.
• Very high number of operating life cycles, reaching up to several million.
• Performance independent of the ambient temperature (-40°C to 65°C).
• No moving parts or chemical reactions.

STORAGE TECHNOLOGY-BASED ENERGY DELIVERY TIMES

Energy generation and storage devices, such as internal combustion engines, fuel cells and batteries, work well as a continuous source of low-power energy. Nevertheless, they may fail to efficiently handle peak power demands or recover energy rationally in many (regenerative) applications, as their discharge and recharge processes of are not as fast and efficient as those allowed by ultracapacitors.

Ultracapacitors are an efficient complement to other energy generation and storage technologies in many of their current applications. They can be part of hybridised storage systems, supporting distributed generation networks and micro-networks.
