    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.

    Abstract: Systems and methods are provided for charging a chargeable electronic device with a USB interface. An example method includes comparing a charging voltage level of a charging device to a charge voltage rage. The method may further include charging a battery with a charging current based on the charging voltage level being within the charging voltage range. The method may further include comparing the charging current to a charge current range, and increasing the charging current based on a determination that it is within the charge current range. The method may involve again comparing the charging voltage level to the charge voltage range and the charging current to the charge current range, and continuing to charge the chargeable electronic device with the charging current based on a determination that the charging voltage level is within the charge voltage range and the charging current is within the charge current range.
