An Optimized Energy Management Strategy of 48V Mild Hybrid Electrical Vehicle to Reduce Fuel Consumption

Abstract

48V Mild Hybrid vehicle has attracted more and more attention recently. Based on United Automobile Electronic Systems (UAES) 48V system, this paper presents us an optimized energy management strategy which mainly consists of operating mode analysis and torque distribution strategy. What’s more, the fuel consumption was tested by UASE Labcar HIL bed in NEDC cycle. Consequently, the oil saving of 48V mild hybrid electrical vehicle can reach 9.24% with start/stop function.
