How does a BEV work?
While driving, the accelerator is sensed and translated to a duty cycle of a Pulse Width Modulated (PWM) Switch Mode Power Supply (SMPS) DC to DC buck voltage regulator that provides current from one or more strings of deep cycle, high power, long life batteries through welding cable, lugs, fuses, and some combination of circuit breakers, main contactors and cutoff switches to the motor field windings that creates a magnetic field. Ions flow from the anode to the cathode of the batteries through the electrolyte, causing current to flow from the anode through the motor to the cathode. In the case of an AC induction motor, the motor position is sensed and the field current is further modulated to induce eddy currents and hence opposing magnetic fields to the field in the rotor that causes the shaft to turn. In a series DC motor, the current goes through brushes to the rotor that creates an opposing magnetic field to the field that turns the shaft. If AC induction, the motor probably can
