Abstract

An apparatus and a method for charging a battery for a vehicle are provided. The apparatus includes a power factor correction circuit that is configured to distribute charging power output from a charging device, which is connected to a power source, to multiple phases, and to correct a power factor of charging power distributed to the respective phases. In addition, a controller is configured to operate the power factor correction circuit to distribute charging power to some of the multiple phases based on the charging device or the charging power of the charging device.

Claims

1. An apparatus for charging a battery for a vehicle, comprising:

a power factor correction circuit configured to distribute charging power output from a charging device, connected to a power source, to multiple phases, and to correct a power factor of charging power distributed to the respective phases; and

a controller configured to operate the power factor correction circuit to distribute charging power to some of the multiple phases based on the charging device or the charging power of the charging device.

2. The apparatus of claim 1, wherein the controller is configured to operate the power factor correction circuit to distribute charging power to some of the multiple phases when the charging device is an in-cable control box (ICCB).

3. The apparatus of claim 1, wherein the controller is configured to operate the power factor correction circuit to distribute charging power to some of the multiple phases when the charging power is less than a preset power.

4. The apparatus of claim 1, wherein the controller is configured to operate the power factor correction circuit to distribute charging power to some of the multiple phases when an allowable charging current duty ratio of the charging device is less than a preset value.

5. The apparatus of claim 1, wherein the controller is configured to measure the voltage of a rear terminal of the charging device, and to calculate an effective voltage value based on the measured voltage.

6. The apparatus of claim 5, wherein the controller is configured to operate the power factor correction circuit to distribute charging power to some of the multiple phases when the charging power of the charging device is less than a preset power and the effective voltage value is equal to or greater than a preset voltage.

7. The apparatus of claim 5, wherein the controller is configured to operate the power factor correction circuit to distribute charging power to some of the multiple phases when an allowable charging current duty ratio of the charging device is less than a preset value and the effective voltage value is equal to or greater than a preset voltage.

8. A method for charging a battery for a vehicle, comprising:

operating, by a controller, the power factor correction circuit to distribute charging power output from a charging device, connected to a power source, to some of a multiple phases based on the charging device or charging power of the charging device.

9. The method of claim 8, further comprising:

operating, by the controller, the power factor correction circuit to distribute charging power to some of the multiple phases when the charging device is an in-cable control box (ICCB).

10. The method of claim 8, further comprising:

operating, by the controller, the power factor correction circuit to distribute charging power to some of the multiple phases when the charging power is less than a preset power.

11. The method of claim 8, further comprising:

measuring, by the controller, the voltage of a rear terminal of the charging device, and to calculate an effective voltage value based on the measured voltage.

12. The method of claim 11, further comprising:

operating, by the controller, the power factor correction circuit to distribute charging power to some of the multiple phases when the charging power of the charging device is less than a preset power and the effective voltage value is equal to or greater than a preset voltage.

13. The method of claim 11, further comprising:

operating, by the controller, the power factor correction circuit to distribute charging power to some of the multiple phases when an allowable charging current duty ratio of the charging device is less than a preset value and the effective voltage value is equal to or greater than a preset voltage.
