Abstract
A method of charging electric vehicles includes charging a high-voltage battery unit with power supplied through two or more inlets. The method includes determining whether the charge amount of the high-voltage battery unit has reached a predetermined charge amount. The method includes charging the high-voltage battery unit with power supplied through one of the two or more inlets and controlling a first switching unit such that power supplied through the remaining inlets is provided to an application component when the charge amount of the high-voltage battery unit has reached the predetermined charge amount.
Claims17
A method of charging electric vehicles, the method comprising:
- charging a high-voltage battery unit with power supplied through two or more inlets respectively connected to two or more external chargers;
- determining whether the charge amount of the high-voltage battery unit has reached a predetermined charge amount;
- and
- charging the high-voltage battery unit with power supplied through one of the two or more inlets and controlling a first switching unit such that power supplied through the remaining inlets is provided to an application component when the charge amount of the high-voltage battery unit has reached the predetermined charge amount,
- wherein the controlling of the first switching unit comprises switching, by a switch connected to the remaining inlets, from a battery charging node to a high-voltage output terminal node based on a first switching control signal.
A vehicle comprising:
- two or more inlets respectively connected to two or more external chargers;
- a junction box configured to provide a charging voltage and current supplied through one of the two or more inlets to a high-voltage battery unit and provide a charging voltage and current supplied through the remaining inlets to an application component or to the high voltage battery unit;
- a first controller configured to control the magnitudes of the charging voltage and current of the two or more external chargers;
- and
- a second controller configured to control the junction box, the application component and the first controller,
- wherein the second controller determines whether the charge amount of the high-voltage battery unit has reached a predetermined charge amount when the high-voltage battery unit is charged with power supplied through the two or more inlets and, when the charge amount of the high-voltage battery unit has reached the predetermined charge amount, charges the high-voltage battery unit with power supplied through one of the two or more inlets and controls a first switching unit such that power supplied through the remaining inlets is provided to the application component,
- wherein the junction box further includes the first switching unit, and
- wherein a switch connected to the remaining inlets in the first switching unit switches from a battery charging node to a high-voltage output terminal node based on a first switching control signal.
