Abstract: Energy feedback can effectively improve the cruising range of new energy vehicles. This article takes the coasting feedback energy recovery system of a battery electric vehicle as the research object, and measures the cruising range of the vehicle under different feedback intensity under world light vehicle test cycle (WLTC) condition, and analyzes the influence of coasting feedback intensity on the energy consumption of the vehicle. The experimental results show that with the increase of the coasting feedback intensity, the energy consumption of the vehicle is gradually reduced first. When the coasting feedback intensity increases to a certain extent, the energy consumption no longer decreases, instead of it will be increases with the increase of the coasting feedback intensity.

Key words: New energy vehicle; Energy feedback; Feedback intensity; Energy consumption
