Constant current high speed charging of electric vehicles via DC grid by using dual inverter drive

摘要

A switching circuit for controlling a charging input from a DC power supply to at least one inverter circuit in which each inverter circuit corresponds to at least one respective battery, and the switching circuit is for the inverter circuit and the DC power supply. In at least one inverter circuit configured to control the charge input provided to at least one each battery when arranged in series and based on at least one voltage of at least one each battery. It is equipped with a switching device that can be controlled together with the switch. [Selection diagram] Fig. 2
