Abstract: Embodiments disclosed herein include an electric vehicle charging system comprising an electrolyte flow system including an anolyte tank having an anolyte solution and a catholyte tank having a catholyte solution. A core stack circuit may be coupled to the electrolyte flow system that is configured to receive the anolyte and catholyte solutions and generate a core stack output voltage and current based on flowrates of the anolyte and catholyte solutions. The EV charging system may further include a DC/DC converter that is configured to receive the core stack output voltage and buck or boost the core stack output voltage based on the core stack output voltage and a charging voltage of an EV. The flowrates of the anolyte and catholyte solutions may be controlled based on a charging voltage of the EV and the core stack output voltage, which can reduce a buck or boost ratio of the DC/DC converter.
