Method & Evidence

AimHow can a hierarchical management system be structured to effectively manage power and energy distribution among multiple energy storage systems in electric vehicles?

MethodConceptual Framework Development and Simulation

ProcedureThe research proposes a modular power and energy management system (M-PEMS) structured into three hierarchical levels: Energy Management Shell (EMS) for long-term decisions, Power Management Shell (PMS) for fast power split decisions, and Power Electronics Shell (PES) for low-level control and interfacing. This framework was then demonstrated, likely through simulation or prototype testing, to manage energy expenditure and power splits for vehicle propulsion and auxiliary loads.
