Question.1 b. False The powe density of ultra capacitor is very high compared to the battery. Since the acceleration and braking is very harsh the vehicle need more power to move the vehicle according to the acceleration. Hence in hybrid vehicles the peak powers are delivered from ultracapacitors and the average powers, …
