An electric regenerative braking system is provided for capturing kinetic energy as electrical potential energy during vehicle braking (also referred to as a braking event). The electric regenerative braking system captures the kinetic energy from a shaft of the vehicle using an electric motor to generate electrical potential energy from the kinetic energy. The generated electrical potential energy is supplied to an energy accumulator that increases in electrical resistance as more electrical potential energy is stored. The electrical potential energy stored in the energy accumulator is used to charge a battery. The electric regenerative braking system uses a controller having a variable resistor to control a braking torque of the electric motor. That is, the controller modulates a resistance of the variable resistor based on the resistance of the energy accumulator, such that the resistance of the variable resistor is reduced as the resistance of the energy accumulator increases.
