Regenerative braking is an important mean to realize energy recovery in the downhill process of electric mining truck. In this study, energy consumption characteristics of mining truck in different driving conditions were studied, driving conditions of electric mining truck and fuel mining truck were collected respectively, driving conditions of mining truck were clustered, energy consumption characteristics of mining truck in different working conditions were studied through data analysis, and energy consumption differences between electric mining truck and traditional fuel oil mining truck were evaluated. The research results show that the electric mining truck can obtain the most braking energy recovery under no-load and heavy-load conditions. Compared to the fuel mining truck, the electric mining truck can effectively reduce the fuel cost by about 83% under the same driving conditions.
