AVL's Range Extender Allows Electrically Driven Ranges equal to those of Conventional Vehicles
2009-05-29 - AVL recently presented its Pure Range Extender that is aimed to extend the range of electrically powered vehicles as well as to reduce the size and costs of the batteries. It is a compact combination of combustion engine and generator that produces electricity on demand and enables electrically powered vehicles to cover a range equal to those of conventional vehicles. At the same time the battery unit can be reduced to one third of its size for example, having a positive impact on the acquisition costs of an electronic vehicle.
The Range Extenders are based on two approaches: based on a "conventional" hybrid vehicle the electrically driven share will be increased and hence the battery will be enlarged. In return the mechanical drive can be reduced until only a mechanic through drive with a transformation ratio remains.
The other approach is based on a pure electrically powered vehicle, which is able to break away of the structural design of current vehicles. One of the main topics for the purely electrically powered vehicles is the range, as the costs for the battery increase considerably with the range. In this case the Pure Range Extender (that is without mechanical pressure) can be used to reduce the size of the battery and thus to reduce the costs. This concept permits a more uncompromising interpretation and optimisation of the combustion engine.
"In the next 15 to 20 years the combustion engines will interact with electric motors by means of a hybrid", Helmut List, CEO of AVL, explains. List is sure that the key for the electric drive is the battery: "On the one hand, AVL concentrates on the optimisation of the battery itself and on the other hand on system developments like the Range Extender, to reduce the requirements for the battery."
