Week-11 Challenge: Braking

OBJECTIVE:

1. For a defined driving cycle, calculate the energy required for braking.
2. Why electric motor can’t develop braking torque at high speed similar to starting? How electric and mechanical brakes are coordinated?
3. Make a MATLAB program which plots contour of given motor speed, torque and efficiency values. Attach the code as a .m file attach a screenshot of all the plots

1)For a defined driving cycle, calculate the energy required for braking.

ANSWER:

CALCULATING THE ENERGY REQUIRED FOR BRAKING FOR A DEFINED DRIVE CYCLE:

• DRIVE CYCLE:FOLLOW THE BELOW FIGURE FOR DRIVE CYCLE TIME Vs Velocity Data
