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 provided In 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 Super-/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 supercaps such as heat dissipation and EMI are solved in a unique way - even the impacts in case of a defect cell are eliminated by a sophisticated balancing. The main performance characteristics of the current finished 1 KW solution being in test operation at various OEM are: Output: 1 kW bidirectional, Capacity: 29.8 F / 12 Cells a 350 F, Additional fused power output, optional output for consumers during motor start, Protection class IP 6K7, Buck/Boost converter 2-phases, Operating frequency 125 kHz, Current control and phase monitoring realized in HW With its scaleable approach and the possibility to be integrated rapidly and cost-efficient 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 clear its way for series implementation, soon.
