Starting Internal Combustion Engines with BOOSTCAPS

• In the framework of a project executed by students of the Automobile Technology Department at the Hochschule für Technik und Informatik (HTI) Biel, it has been demonstrated that it is possible to start an internal combustion engine with BOOSTCAP ultracapacitors instead of a lead acid battery. These tests have been performed at a test bench and with a real car.

Findings

• BOOSTCAPs are able to start an ICE.
  
• The weight of a starting unit with ultracaps is about 1.7 kg.
  
• Because the total cycle life should be much higher than the one of a lead acid starter battery, this solution is very interesting for:
  
  • ICE for stationary use
    
  • tool for starting aid (TCS, AAA, garage)

thanks , that looks a lot better than my intro..

Since original publication of this document, further enhancements have been made to ultracapacitor technology enabling improved performance over that listed within this application example. The product referenced is obsolete and has been replaced with newer technology. The methodologies cited within this document are unaffected.

This is some very cool technology here..battery manufacturers look out.
