Design and verification for the power performance parameters of micro-electric vehicle with four-wheel-independent drive

According to power performance requirements of independent designed micro-electric vehicle with four-wheel-independent drive,the matching design of drive motor power,the capacity and number of battry was performancd. By using software AVLCruise,a simulation analysis on its power performance was conducted. The parameters were used in the design of electrical system and component parameter selection. Finally by real vehicle test,the result showed that the relation parameters of powertrain system met design requirements,the drive current graph of trunk circuits in different driving modes was suitable.
