ENERGY CONVERSION MODULE (ECM) - DC/DC CONVERTER WITH INTEGRATED SUPERCAPS

摘要

In the light of increasing hybridization of future vehicle generations mainly those functionalities will be realized which contribute to fuel- and at the end emission-reduction. Recuperation, Start-Stop, E-steering and EDS-stabilization therefore constitute applications for which an efficient energy management has to be providedIn this context ALCOA / AFL Europe GmbH developed a patent pending system solution, by which in one single unit a powerful DC/DC converter is integrated with the storage medium EDLC or Supcr-/Ultracap - on the one hand the restrictive packaging and on the other hand high performance requirements of the OEM can be met in a high degree. Possible issues arising from the compact integration of the supcrcaps such as heat dissipation and EMI are solved in a unique way - even the impacts in case of a defect cell arc eliminated by a sophisticated balancing.The main performance characteristics of the currently finished 1 KW solution that is in test status at various OEMs are:1. Output: 1 KW bidirectional2. Capacity: 29,8 F /12 Cells a 350 F3. Additional fused power output4. Optional output for consumers during motor start5. Protection class IP 6K76. Buck/Boost converter 2-phascs7. Operating frequency 125 kHz8. Current control and phase monitoring realized in HWWith its scaleable approach and the possibility to be integrated rapidly and cost-efficiently in new carlines, the ECM just today combines the advantages of an intelligent electric power management. New prospective application-ranges - i.e. up to 5 KW for commercial vehicles and/or buses - are right now under development and should move its way in to scries implementation soon.
