Mathematical model of vehicle electrical energy recovery

Abstract

Nowadays, the most energy efficient are electric and hybrid vehicles. Despite the very high cost and insufficient design perfection, they are replacing traditional cars with internal combustion engines. In hybrid vehicles, it is relatively easy to implement energy storage systems using reversible electric machines and electric batteries. The results of a study on electrical energy generation in a vehicle are presented. The methods of mathematical and simulation modelling were used. The efficiency of operation of a vehicle with an electrical energy recovery unit is shown. The data of the generated electric current in the form of the received voltage when the vehicle is moving on various types of road surfaces are given. As a result of simulation modelling, it was found that one recuperator can generate an average of about 3 V, 12 V can be obtained from all four installed recuperators, which is enough to charge the storage units of the hybrid power plant.
