Sammanfattning

In order to obtain the maximum efficiency from a

hybrid driveline it is crucial to optimize the power

distribution between the electric drive and the internal

combustion engine. An accurate estimation of how much

electric power can be delivered at any instant of time is

therefore of great interest. Such estimation is dependent on

several factors, as the state of charge of the battery, the

temperature and the cooling conditions of the motor and the

power electronics at that particular moment. This article

proposes a method for evaluating the overloading potential of

the electric drive dynamically at any time, based on a

previously developed thermal model. Alternative modelling

techniques are discussed and the resulting thermal model is

validated against experimental measurements.
