Power train design and build up of EV born car using power flow analysis

Full Electric Vehicle [FEV] technology is the most efficient one (4 times efficient) than conventional gasoline engines. Huge vehicle design of FEV leads to more power savings than the smaller one. Resizing of the current Electric Vehicle [EV] to higher range or conversion from conventional vehicles to EV of required size is not advisable and may results in fall of efficiency of the system. Selection of motor and energy storage is very essential part in the design and buildup of EV. It is required to analyze the power flow from the battery to motor for proper selection of battery size, power train and motor to achieve stability of the system. Mathematical modeling of power flow analysis considering mechanical and electrical parameters is built using MATLAB/Simulink tool which is essential for the selection of motor and energy storage systems. Tractive force is analyzed by mathematical modeling for flat road, ±5

gradient & acceleration variation conditions. A four wheeler electric born car is designed and built from the base with modified frontal area in order to reduce the aerodynamic drag force that in turn increases the efficiency and renders battery a cooling system. The sizing of motor and energy storage system is obtained from power flow calculations. The four wheeler 3 seater capacity car is designed and built with 3 kW permanent magnet synchronous motor [PMSM] and 2.4 kWh Lithium Iron phosphate [LiFePo4] battery pack and tested for speed, acceleration and power. The practical results of speed, acceleration, load carried and power output of power electronic converters are in conformation with mathematical modeling of EV born that uses the concept of power flow analysis.
