配置48V系统后汽车的节油效益研究
Research Overview of 48V System's Fuel Saving Potential for Automobiles
摘要
Abstract
Solenoid valve controlled hydraulic components are being substituted by eclectic motors in vehicles gradually.48V system provides reliable framework for the devices composites of driving motors and control motors.ICE can achieve better fuel efficiency with the support of some 48V techniques,such as e-supercharger,intelligent cam phase adjustment,and variable compression ratio engine,etc.48V system makes it feasible to drive cooling pump or oil pump by electric,so that the energy consumption could be reduced and engine structure could be simplified.The weakness of DCT and CVT transmission can be overcome by applying 48V control motors,while the power loss due to their auxiliary parts is reduced too.Coasting function may function properly in support of 48V system,and fairly amount of fuel can be conserved as the result of longer coasting.Active adjustment of suspension height and active grill shutter technique can also benefit from higher control voltage.More electric energy can recovered in brake phases by 48V motor,which will be released later to power many devices.Accessories can be of higher efficiency and better performance in 48V system,such as active seat ventilation.LFP,LVP,LTO and NMC lithium battery are choices for electric storage in 48V system.48V system enables many techniques of fuel saving potential.关键词
