1. A system for determining a range of an electric vehicle, the system comprising:
a sensor to generate a signal indicative of a current being supplied by a battery of the electric vehicle to a motor of the electric vehicle for driving the motor, wherein the sensor is to be disposed in a non-contact arrangement relative to a wire that is to supply the current; and
a controller to:
determine the current supplied by the battery to the motor based on the signal generated by the sensor;
receive a voltage supplied by the battery to the motor;
determine a notional distance travelled by the electric vehicle, wherein the notional distance corresponds to a number of rotations of a wheel of the electric vehicle while being disposed on a test bench; and
determine the range of the electric vehicle based on the voltage, the current, and the notional distance.
