Systems and Methods for Efficiently Charging Power Recovery Controller

Abstract

The inventive subject matter provides systems and methods for efficiently charging a battery of a vehicle using a regenerative braking system. In one aspect of the invention, the battery charging system includes a regenerative braking system that is configured to convert mechanical energy from braking of the vehicle into electrical energy. The battery charging system also includes a bank of capacitors that is configured to store the electrical energy generated by the regenerative braking system. The battery charging system also includes a circuit that is configured to feed into the battery at least a portion of the electrical energy stored in the bank of capacitors as a series of current pulses at a frequency that corresponds to a resonant frequency of the battery. The series of pulses includes constructive resonant ringing that is constructive with respect to charging the battery.
