Abstract

A battery-to-vehicle charging system includes: a vehicle including an on-board charger including a power factor correction circuit having a boost converter circuit, a first battery that is charged with a charge voltage output from the on-board charger, and a first controller controlling a charge process based on a type of a charge power source provided from the outside; and a mobile energy storage device including a second battery storing a direct current (DC) charge power to be provided to the first battery, and a second controller providing a determination signal for the type of the charge power source to the first controller, in which when the first controller receives the determination signal from the second controller and the charge power source is determined as a mobile energy storage device, the first controller controls the power factor correction circuit to operate as a boost converter.

Claims7

Dependent claims

A battery-to-vehicle charging system comprising:

a charging inlet having a plurality of terminals to which a connector of an external charge power source is coupled, wherein the plurality of terminals has a power input terminal to which an alternative current (AC) charge power and a direct current (DC) charge power are alternatively applied from the connector and a signal terminal to which a control signal for charging is provided;
an on-board charger including a power factor correction circuit that has an input terminal connected to the power input terminal of the charging inlet and has a boost converter topology;
a battery that is charged with a charge voltage output from the on-board charger;
and
a controller determining a type of the charge power based on the control signal input from the external charge power source through the signal terminal of the charging inlet, and controlling a charge process based on the determined type of the charge power,
wherein the controller controls the power factor correction circuit to operate as a boost converter when the determined type of the charge power is a DC power having a voltage lower than a voltage of the battery.
