Abstract

A charging and discharging apparatus includes, in some implementations, an alternating current charging and discharging unit, a bidirectional alternating current/direct current conversion unit, a bidirectional direct current/direct current isolated conversion unit, and a first energy storage unit that are sequentially connected in series, and further including at least one switch unit, a direct current/direct current isolated conversion unit, and a second energy storage unit. A first end of each switch unit is connected to the bidirectional direct current/direct current isolated conversion unit, a second end of each switch unit is connected to a first end of the direct current/direct current isolated conversion unit, and a second end of the direct current/direct current isolated conversion unit is connected to the second energy storage unit.
