Week-11 Challenge: Braking

What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type?  MAPPED ENGINE: The Mapped CI Engineblock implements a mapped compression-ignition (CI) engine model using power, air mass flow, fuel flow, exhaust temperature, efficiency, and emission performance…

Aim: For a defined driving cycle, calculate the energy required for braking. Why electric motor can’t develop braking torque at high speed similar to starting? How electric and mechanical brakes are coordinated?  Make a MATLAB program which plots contour of given motor speed, torque and efficiency values. Attach…

  Run MATLAB demo ‘Speed control of a DC motor using BJT H-bridge’. Modify the model such that armature current doesn’t shoot up when motor changes direction from forward to reverse.  power electronics: power electronics is the application of solid-state electronics to the control and conversion…

Which types of power converter circuits are employed in electric and hybrid electric vehicle? there are four different types of power converter circuits are used. the power converter circuits are also known as power converter circuits. the power converter circuits converts one form of energy to another form. this converted…
