Ultracap modules in automotive applications

The classic lead-acid battery in cars or trucks is still the standard today. In general, it is still a cost-effective and reliable solution. Nevertheless, low oper­ating temper­atures and frequent restarts can bring such batteries to their limits - "the battery gets tired". A problem that is exa­cerbated by environ­mental regu­lations. Delivery services must switch off the engine even during short stops, or must be equipped with an auto­matic switch-off system.

Operational safety: modules to stabilise the on-board network

For greater operational safety, ULTRACAP modules have therefore become established as support for the on-board network. For this purpose, we offer the TRUCKSTARTER module CAP-XX and the voltage stabili­sation modules from PUREECHEM.

Advantages for on-board power supply stabilisation

  • Regulation of unstable voltage situ­ations caused by the alter­nator
  • Stabilisation of idling
  • Improved performance of head­lights and audio equip­ment
  • Increased battery life
  • Increasing combustion efficiency for more power/torque

The large TRUCKSTARTER module from CAP-XX is not only suitable in low tempe­ratures, but also in summer when the air condit­ioning puts addi­tional strain on the on-board batteries.
Weak batteries receive enough support from the modules that the starter motor can be started.

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
