Abstract: This paper takes heavy-duty pure electric vehicles as the research objects and conducts energy consumption and driving range tests under high and low temperature environments.It investigates the appropriate method for resistance setting to ensure the rationality and reliability of test results,which accurately reflect the impact of different environmental conditions on energy consumption and driving range.Based on the analysis of the validation test results,the following calculation method for determining alternative resistance is proposed:Increase the sliding resistance or the recommended resistance in a normal-temperature environment by 10%to obtain the alternative resistance for a low-temperature environment and decrease it by 5%to obtain the alternative resistance for a high-temperature environment.
Key words: heavy-duty pure electric vehicle; resistance setting; high and low temperature environment; energy consumption; driving range
