Abstract:

In alignment with Canada’s goal to achieve net-zero emissions by 2050, Battery Electric Vehicles (BEVs) are being introduced in mining to replace conventional Internal Combustion Engine Vehicles (ICEVs), which will help reduce carbon emissions, and improve efficiency and related heat contribution. Further understanding of BEV technology and performance under different working conditions is essential for designing a new mine or transforming an existing fossil fuel-based fleet into an electric mine. The Rokion R400 utility BEV was tested at an Ontario mine site on a 2.5 km test route comprising 10 sections of various grades: flat (0%), 5%, 10% and 20% inclination. The test consisted of driving the BEV through the 1.25 km test route in both directions to complete a lap (2.5 km), at two different loads (mid and full) and two speeds (5 km/h and 15 km/h). The test plan included multiple laps for each load and speed. This paper presents the results of the test in terms of power and energy consumption and generation tabulated by inclination grade, speed and load. The battery state of charge and the charging data are also presented to highlight the complete BEV process and capabilities.
