Project

Objective :

The main objective of this project is to obtain speed by driver, to estimate the temperature of motor and controller, to estimate SoC and distance travel by the vehicle. There is a SoC block that will estimate the state of charge of battery, distance is calculated by speed and time parameter for FTP75 cycle.

The Eletric 3 wheeler model will be built with following assumptions

• Battery Type Lithium Ion 60.8 V 160 Ah
• Vehicle kerb weight 260 kgs
• Load capacity 340 kgs
• Vehicle speed 7 kmph
• Driving range 140 km
• No of wheels per axel 2
• Frontal Area 91m²
• Drag coefficient 5
• Wheel radius 306m
• Vertical load 3000 N
• Nominal Voltage 8 V
• Rated Capacity 160 Ah
• Initial SOC % 100
• Internal Resistance 5 ohm
• Motor Voltage :48V ,Power rating 650-1400 W
