Systems and methods for on-board EV charger and regenerative braking

A method for discharging an electrochemical device of an electric vehicle to power a motor, the method comprising:

• generating a first shaped discharge signal and a second shaped discharge signal from the electrochemical device providing power to the motor;
• and
• receiving, at a motor controller, the first shaped discharge signal and the second shaped discharge signal;
• wherein generating the first shaped discharge signal comprises receiving, at a first pair of switching elements coupled with an inductor within the motor controller, a first PWM control signal to control the first pair of switching elements to form the first shaped discharge signal and generating the second shaped discharge signal comprises receiving, at a second pair of switching elements within the motor controller, a second PWM control signal to control the second pair of switching elements to form the second shaped discharge signal.
