| Abstract |
Restricted battery capacities and long charging times for battery electric vehicles (BEV), range extendervehicles are a good alternative to reach a bigger range. This paper describes how an operation strategywhich is adapted to the power requirements of the driving cycle is used to increase the range of rangeextender hybrid vehicles. Adaptation of the range extender unit’s power output to the momentary performancerequirements of the vehicle or reduction of the constant power to a route-specific optimum valueallows a significantly bigger range as well as less stress on the battery than a conventional single-pointstrategy at the efficiency optimum. Moreover, two vehicle configurations are examined. In differentdriving cycles two operation strategies are examined (constant power supply and variable power supply)and the results are shown in comparison to the single-point operation strategy. |
