How supercapacitors changed the world

Supercapacitors or ultracapacitors are now centre stage for the designers of electronics and particularly power circuits. They are improving faster than the batteries and electrolytic capacitors they increasingly replace.

Stop/Start Problems Could Charge The Ultracap Market

Inefficiencies and durability questions cropping up with now-proliferating stop/start systems could be opening the door for long-promising, but little applied ultracapacitor technology in the light-vehicle market.

Supercapacitors for the Supergun

It is well known that supercapacitors can send out their entire charge almost instantaneously and are capable of millions of charge/discharge cycles without degradation. What’s more they have extremely low internal resistance or ESR and offer cycle stability in a wide temperature range – from +65 °C to -40 °C (batteries can’t perform well below 0 °C).

How to kill an ultracapacitor

When working within their specified operating parameters, ultracapacitors will provide a stubbornly long and trouble-free existence. Ultracapacitors will outlast most other electronic components in any given application, which is why they are the perfect power delivery device in the most demanding environments.

Win Inertia will Incorporate Maxwell Ultracap in Rail System

SAN DIEGO, Aug. 19, 2014 /PRNewswire/ — Maxwell Technologies, Inc. (Nasdaq: MXWL) announced today that Win Inertia, an engineering firm specializing in power electronics, energy storage and control and communication systems, is using its ultracapacitors for a stationary wayside braking energy recuperation system at an electric rail system in Cerro Negro, Spain. Win Inertia designed and installed the system under a contract with the Spanish government’s Administrator of Railway Infrastructures (ADIF). In this installation, the system also enables ADIF to store excess energy in a battery bank that supplies an electric vehicle (EV) charging station located at the rail station. The facility also seamlessly integrated a photovoltaic (PV) generator to supply additional energy if required.
