Research on Power System Matching of Pure Electric Commercial Vehicle

In this paper, four powertrain schemes are designed based on pure electric commercial vehicle. According to the
requirements of the vehicle's dynamic performance and economic index, the parameters of the power system were first
matched, and then the speed ratio parameters of the transmission system were optimized by using the multi-island genetic
algorithm. Finally, the actual operating conditions of xi'an city were imported into the cruise software for simulation
comparison. The results show that the performance of the vehicle can be improved by optimizing the speed ratio parameters.
The four powertrain schemes designed meet the requirements of the vehicle performance index under the actual working
condition in xi 'an, among which the double-motor powertrain scheme is more economical.
