Whenever batteries are used in an application, it is always worth considering whether ULTRACAPS could provide a more reliable and more cost-effective solution in the long-term. ULTRACAPS are not always the most practical solution and in some cases they cannot be used at all. There are some applications, however, where using a capacitor is useful and more efficient. ULTRACAPS are always an advisable solution if charge cycles are frequent, if large currents need to be stored or made available quickly or if harsh conditions or low temperatures can be expected.
Thanks to the incredible capacitance of single cells, reaching up to 3000F, modules can be created that are so large that they enable trams to travel great distances without overhead lines, with the energy generated by the braking process being stored (recuperation).
High-performance cells of up to 3000F with very low internal resistance are used for energy recovery in applications such as buses and commercial vehicles, significantly helping to save fuel, lower costs and reduce CO2 emissions.
Supercaps are innovative energy storage devices that are being used in an increasing number of application areas, thanks to their particular technical characteristics. Their original key application, as a primary energy storage system (e.g. tank) in cars, soon turned out to be the wrong approach. Fortunately, it took little time for other applications in the industrial and energy technology sectors to be found.
The key application of pitch control in wind power stations is a prominent example. Supercaps quickly became established as energy storage systems for emergency power supply in such systems, thanks to their great cycle stability.
The benefit of this solution is the low maintenance of the storage. Maintenance in wind power plants is expensive and system down-times cost money.
Recuperation of braking energy in buses and trains contributes to energy savings and thus also to CO2 reduction. Supercap (Ultracaps) can be used in the negative temperature range down to -40 °, so they are also suitable for particularly harsh environments as energy storage. Supercap can not only quickly absorb large amounts of energy, but also release very quickly. This feature allows large currents to flow in the shortest possible time, providing short-term power without being destroyed.
Small cylindrical cells have also proven their versatility. These capacitors are, for example, fitted in battery-free flashlights, remote controls, measuring equipment and much more. They are charged via induction or other suitable means. The ultracaps have proven themselves many times over as memory back-up in embedded applications. Ultracaps can be used to prolong the service life of batteries. The potential range of applications is virtually unlimited.
Ultracaps are finding increasing use in many areas as a battery replacement or as a battery addition to conventional batteries. Ultracaps are ideal for covering short-term peak performance and recuperation (energy recovery).
Depending on the application come cells or modules are used.
