Method to reuse the pulse discharge energy during Li-ion fast charging for better power flow efficiency

A battery charger for charging a battery with voltage from an input supply and method for using are disclosed. The battery charger may comprise a power path (e.g., one or more circuit stages, a step down stage, a step up stage, etc.) to drive the battery during a pulse charging sequence in a first m...

Beschreibung
Zusammenfassung:	A battery charger for charging a battery with voltage from an input supply and method for using are disclosed. The battery charger may comprise a power path (e.g., one or more circuit stages, a step down stage, a step up stage, etc.) to drive the battery during a pulse charging sequence in a first mode and to reverse power flow from the battery when operating in a boost mode during the pulse charging sequence. An energy storage component may be coupled to the power path to capture pulse discharge energy during the pulse charging sequence when the circuit stage is operating in the boost mode.
