Q1. For a defined driving cycle, calculate the energy required for braking. Answer :-   Deceleration conditions are similar to acceleration conditions. Acceleration increase in speed and deceleration is a reduction in speed. So similar way to calculate braking power. Where M= mass of the vehicle.  …

1. A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. Answer :-      BJT H-BRIDGE:                 An H-bridge is an arrangement of transistors that allows a circuit full control over a standard electric DC motor.…

1.What is the difference between the mapped and dynamic model of engine, motor, and generator? How can you change the model type?   MAPPED models: Mapped models are used when the behavior of a particular model is not of our interest and can be modeled with predefined values in the form of lookup tables. eg: mapped motor:…

AIM: Use the ADVISOR tool and simulation the following: Q.1: For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle. Conclude your observations. Q.2: In the above case, try changing the battery capacity and repeat the simulation. Q.3: Perform…
