Determination of parameters of a hybrid car powertrain by modeling of the energy consumption process

Abstract

During operation of a hybrid powertrain with intermediate buffer energy storage, an inadmissible decrease in the amount of of stored energy may occur. The parameters of hybrid powertrain elements should be chosen so as to minimize the probability of such cases. This article describes a method for calculating powertrain parameters based on representation of energy consumption as a random function. The method is described by the example of a passenger car powertrain. The dependence of the minimum required power reserve of the primary energy source and minimum required buffer energy storage capacity is shown. The described method can be used to calculate the primary energy source power and buffer energy storage capacity of different hybrid vehicles using a random function specifying their energy consumption. Application of the method requires further experimental investigation of these parameters of random functions.
