Ultracapacitors offer short-term power boost

October 30, 2012 // By Julien Happich
As proven energy storage devices, ultracapacitors can replace conventional capacitors or batteries in applications that require significantly more energy than conventional capacitors can provide.

Nesscap ultracapacitors provide additional support in a wide range of applications such as water meters, which record data used to profile energy use, monitor flow, forecast demand, demand response, record rate of flow, detect leaks, water and energy conservation enforcement and even remote shut down of supply. Generally the battery, as the sole energy source, is not able to deliver the power required over its lifetime. Nesscap's ESHSR range of 3F and 5F 2.7v cells and the EMHSR 1.5F and 2.5F 5v modules are a highly cost effective way of resolving these power issues. The 3F cell measures 8x20mm, the 5F cell 10x20 and the 1.5F module 9.5x23x17.5mm and the 2.5F module 12x23x21.5mm. 

These ultracapacitors have an operational life of a minimum of 500k cycles or 10 years, or longer with voltage/temperature de-rating. Each ultracapacitor has an operational temperature range of -45 to +65°C , and they are easy to mount by automatic insertion machines. With up to 10 times the power of standard lithium batteries, ultracapacitors carry no memory effects, cannot be over-discharged and can be held at any voltage at or below their rating. In addition, by keeping the ultracapacitors within a specified operating temperature and voltage range, they can be maintenance free.
