Optimized designed controlled driver circuit of a three-wheeled electric vehicle and implemented in hardware

摘要

This paper proposed modeling, designing and battery management system for a three-wheeled electric vehicle for the Indian road under different conditions. The system consists of a lithium nickel manganese cobalt oxide cell-based lithium-ion battery with a managing system known as battery management system (BMS) described here. The process for modeling the vehicle, choosing the motor, developing the controller with a programmable circuit and developing the DC–DC buck converter, and battery pack of the lithium-ion cell with an effective BMS is discussed. According to the study, a prototype programmable controller circuit board, including the PWM-controlled driver circuit, is built for the proper flow of electricity on urban roads in India and has been tested successfully on road. This developed electric prototype travels the range of 100 km with an average speed of 32 km/h, while the maximum current drawn from the battery is 30_amp. The efficiency increased by 2 compared to the market-available PWM square wave controller. MATLAB simulation is done to compare the effectiveness of the modeled system with the suggested prototype control system. To verify the system, a small-scale prototype is developed.
