Range extender module

Robert Fischer; Günter Karl Fraidl; Christian Hubmann; Paul Kapus; Ralf Kunzemann; Bernhard Sifferlinger; Frank Beste

The use of AVLs Pure Range Extender module as a serial hybrid solution is described. The AVL concept is optimised for electric power generation in single-point operation and allows a compactly integrated, cost- and weight-efficient module design. In addition to its use in simplified four-stroke designs the Pure Range Extender can be applied to emission-optimised and fuel consumption-optimised two-stroke and rotary piston engines. Details are given of the reductions in weight and running costs and the increases in range that can be achieved. The development process is discussed and the key specifications of the Pure Range Extender provided in a table. The design of the internal combustion engine and generator-starter are considered in more detail. A feature of the system is its flexible design which will allow its use in a wide variety of vehicles.

Fur eine breite Akzeptanz von Elektrofahrzeugen erscheint ein Range-Extender als serielles Hilfsaggregat fur einzelne langere Fahrstrecken von entscheidender Bedeutung. Der Ansatz von AVL ist auf Batterienachladung im Einpunktbetrieb ausgelegt und ermoglicht ein kompakt integriertes, gewichts- und kostenoptimiertes Modul. Der Verbrennungsmotor des sogenannten Pure-Range-Extenders von AVL kann neben vereinfachten Viertakt-Konzepten auch als, fur die Anwendung optimierter, Zweitakt- beziehungsweise Rotationskolbenmotor ausgefuhrt werden
