Comparison of 12 V network power supply strategies in a conventional vehicle and the effect on fuel consumption

Popis výsledku v původním jazyce

The main purpose of 12 V onboard electric network is to power several key vehicle systems and number of other onboard consumers. For this purpose, the Internal Combustion Engine Vehicles (ICEVs) are equipped with an alternator and a 12 V battery. As the number of vehicle systems and control units in vehicle is increasing and the start-stop system is widely implemented, much higher demands are placed on the alternator and 12 V battery. With stricter limits on CO2 emissions, it is necessary to focus on the 12 V network power supply strategy. The aim of this work is to compare several approaches to powering the onboard network. The first variant is a strategy of maintaining a constant voltage of the 12 V battery. The second variant distinguishes several voltage targets for different driving modes based on the actual SOC, Internal Combustion Engine (ICE) speed and actual required power necessary to drive the vehicle. For this purpose, a 1D simulation model of a conventional car was built in the SW GT-Suite, charging strategies were implemented and the effects on fuel consumption were compared.
