I know that speed is proportional to voltage and torque is proportional to current. Now, consider example of uphill driving. When we press accelerator paddle, what exactly happens?
In: Technology
The electric engine kicks up a bit (computer controlled) and outputs more torque. It is no different than the concept for an electric motor on a power tool or in a RC car.
Many EVs use induction motors which don’t vary speed based on voltage. The frequency is what controls the speed of rotation. EVs don’t use typical brushed DC motors, they make 3 phase AC (Aka brushless “DC” motors).
