Summary
The development towards battery electric vehicles will continue steadily in the coming years. A main reason for this is the need to meet future fleet fuel consumption and emission targets. Through the progress to be expected regarding battery charging
infrastructure, battery capacity, sufficient driving range, vehicle weight and cost, the obstacles which may hinder this development will be eliminated.
This article deals with transmissions within the powertrain of battery electric vehicles. While 1-speed transmissions are common and sufficient today for many vehicles, there are also applications for which the use of 2-speed transmissions is advantageous.
Reasons for this will be presented. Furthermore, a modern 2-speed transmission family will be introduced which ensures both load shifting capability and sailing operation in addition to recuperation.
