Abstract: New energy vehicles is one of the important parts for environment protection in the future, and the energy feedback technology can be a significant method to make new energy vehicles run efficiently. Energy feedback technology contains two ways, one is coasting, the other is braking feedback. During energy feedback, the mechanical energy can be translated to electric energy by motor, the energy is stored in the battery for further consumption. Based on plug in hybrid electric vehicle (PHEV), this article is focused on designing various coasting energy feedback methods, tests the electricity consumption at new European driving cycle (NEDC), analyzes the differences among various coasting methods, and provides the direction for calibration.

Key words: Energy feedback; Electricity consumption; Control strategy; Plug in hybrid electric vehicle; Coasting feedback style
