The
figure 3 above represents the voltage, current and the electric power graph versus time plot. The
voltage and current are calculated by ammeter and voltmeter at every time interval, present in battery
circuit. The Electric power is measured by product the voltage and current input value, we get the power
curve. And as in the graph the power increases at 20s due to acceleration by motor to 20 KW, then motor
attends the stable speed so it consume power up to 60 KW and decreases at 140s due to deacceleration
and then it shows negative power that means the engine shaft power
is also transferred to the
motor/generator to recharge its battery and after recharge it gains back 0 KW.
The figure 4 above shows the engine parameters with respect to the time the A) is the fuel consumption
as u can see the fuel consumption is increased at 20s up to 0.0006 Kg/s because the vehicle wheels are
powered by motor so there is less fuel required than actual amount to accelerate the vehicle by the engine
only and then decreases again back to around 0.0002 Kg/s for maintain the vehicle speed. B) is the
Power of the engine which is also increased during the acceleration is slightly increased due to some
increase of speed of the shaft. And after 140s when the motor stops powering the drive shaft,
the power
