Analysis Energy Saving Potential Of Energy-saving Auto

With the tension of today’s society energy problem improving, the trend of using Energy-saving auto and New energy vehicles have been irresistible. In order to accomplish Energy conservation and emission reduction and excavate the potential of Energy-saving auto the article analyzes the Energy-saving potential of Energy-saving auto in three aspects to optimize the control strategy.Since the techniques of engine that HEV using has been basically mature and the differences between the best and worst working points is less, the working point could be basically maintain at a condition of low fuel consumption by using the auxiliary drive of the engine. While the optimization of control strategy which based on the best economic work curve manifests that the process that the engine drives motor for the battery is consuming because of the inefficiency of the motor. In short, the potential of optimizing the whole is not big.The saving effect of auto stop is much obvious. It was found through the simulation analysis of the auto stop that the oil saving effects best when idles20s, almost1L oil could be saved per100km. But due to the recent control strategy can’t calculate the stop time correctly, the effect of auto stop is greatly impaired and the energy saving potential is largely limited.The Potential of braking energy recovery is tremendous. Making the maximize regeneration of Brake Energy as optimize purpose to optimize the control strategy and considering the charging efficiency of the motor totally could increase18%road haul indirectly. And the increased recovery of Brake Energy could greatly improve the battery’s SOC value, lessen the frequency that the engine drives the motor, enhance the ability of the auxiliary drive of the engine and boost the effect of Energy conservation and emission reduction indirectly.In conclusion, there are great rooms for the Energy-saving auto to improve and the most perfect way at present to improve the Energy-saving auto’s oil saving potential is to enhance the ability to regeneration of Brake Energy.
