Safe power management system for electric vehicles using fuzzy logic control

Abstract

The vehicular technology is going through a new paradigm. Guidelines must be determined, in the emissions control and the smart usage of the non-renewable energy sources becomes reality. Nowadays, electric vehicles are an option to mitigate these issues. Viewed as an electronic device, the electric vehicle’s consumption has to be managed efficiently due to a limited battery life and the high cost of these energy storage devices. In this bachelor final project, a Safe Power Management System (SPMS) of an electric vehicle, which is a subsystem of an Energy Management System (EMS), is developed. EMS is a power split manager focused on distribute the power to the vehicle main subsystems, always seeking the integrity of the whole set and the reduction on energy consumption. The system uses a Fuzzy Logic Controller, as the control strategy to the electric energy consumed by the electric vehicle.
