ANSWER : let us consider the cell with  nominal voltage =3.6 v capacity = 3500mAh=3.5Ah convert the battery capacity 150kw to Ah  by the help of the power formula which is  P=VI here the voltage given is 120v =150*1000=120 *I I=15000/120 = 1250Ah a) series :  Number of cell in series = required voltage…

ANSWER :  INTRODUCTION:   The electric vehicle is one that operates on an electric motor instead of an internal combustion engine that generates power by burning a mix of fuel and gaes. EVs use electricity to change their batteries instead of using fossil fuels like petrol or diesel. they use an electric…

ANSWER :1 The function of the braking system is to retard the speed of the moving vehicle or bring it to rest in the shortest possible distance whenever required. The vehicle can be held on an inclined surface against the pull of gravity by the application of a brake. Brakes are mechanical devices for increasing the…

ANSWER 1.A : H bridge : An H-bridge is a simple circuit that lets you control a DC motor to go backward or forward.   A DC motor spins either backward or forward, depending on how you connect the plus and the minus. If you close switch 1 and 4, you have plus connected to the left side of the motor and minus to the…

ANSWER 1:  Power Electronic Converters: - In Electric and Hybrid Electric Vehicles (EV/HEV), the power electronic converters are considered as the key elements that interface their power sources to the drivetrain of the EVs. In order to design highly efficient converters for the EV’s power system, advanced DC/DC and DC/AC…
