Electric Vehicle Dynamics — Lesson 1

This lesson covers the dynamics of electric vehicles, focusing on the power and energy requirements for their operation. The lesson also discusses the specifications of the motor and batteries needed for an electric vehicle, based on the vehicle's requirements. It introduces the concept of vehicle dynamics and how it helps in determining the power, energy, and torque required for the vehicle. The lesson also touches on the concept of regeneration in electric vehicles, where some of the energy used for acceleration or climbing can be recovered during deceleration or descent.
