Ultracap Modules

Supercap modules are a promising alternative to batteries for energy storage systems, especially for highly cyclically loaded systems such as AGVs or manu­facturing operations. Unlike batteries, super­caps can absorb and release large amounts of energy quickly without ageing or wearing out. CAPCOMP has many years of experience in designing complex energy storage systems with standard ultracap modules for statio­nary and mobile solutions in AGVs, as well as customer-specific special systems.

Ultracap modules are climate protection

The enormous capacity of individual cells of up to 3000F enables the production of large-scale modules, so that, for example, trams can travel long distances without an over­head line and store the energy gained during braking (recuperation).

High-power cells of up to 3000F and very low internal resistance are used, for example, in buses and com­mercial vehicles for energy recovery and contribute signi­ficantly to fuel savings, cost savings and emission reductions of CO2. In addition, the high perf­ormance modules can be used at operating temperatures of up to -40°C.

Ultracap modules in wind turbines

Pitch control, or blade pitch control, in wind turbines is a prominent example of the use of high-perfor­mance modules. The benefit for the user in this solution is the low maintenance of the accumulators. Mainte­nance work on the wind tur­bines is expen­sive and a failure of the system costs addi­tional money.

In addition, supercaps have established them­selves in this industry as energy storage for emer­gency supply due to their cycle stability.

Who can place an Order with us?

All those who have registered a trade. We supply to large customers as well as medium-sized companies, small busi­nesses and engineering offices. Schools, colleges, univer­sities and public institu­tions are also provided with technical advice and supplies. Depen­ding on the purchase quantity and product, we grant staggered prices that can vary on a daily basis. Ask us for an indivi­dual offer.

Do I have to order online in the shop?

No, you are also welcome to request an individual offer. The ordering option at shop24.capcomp.de is particularly suitable for smaller quantities. The WEBSHOP is to be understood as an additional service offer where you can get a quick overview of availability, delivery times and prices. Furthermore, with its filter and search function, the shop also offers a quick overview of the different variants, designs, voltages, currents. Our stock in Freiberg am Neckar (South West of Germany) is well stocked for the common types. Provided that our suppliers accept it, special solutions are also offered here. In this case, we recommend that you ask us about delivery times.

Why are components like ultracaps called different names?

The variety of terms is explained by the English-language terms commonly used in the electronics industry, which are often mixed with German terms or used synonymously. In some cases, manufacturers have also introduced artificial terms to better distinguish themselves from competitors. Here are the most important examples:

Double layer capacitors (DSK) are referred to synonymously as:

  • EDLC (Electric Double Layer Capacitor)
  • Supercapacitors = Supercaps
  • Ultracapacitors = Ultracaps
  • Goldcap™ [Panasonic]
  • Boostcap™  [Maxwell]
  • Greencap™  [Samwha]
  • PURIXEL™  [Pureechem] for supercap cells
  • PURETRON™  [Pureechem] for supercap modules
