Abstract
An embodiment charging power filtering method includes receiving a signal instructing whether or not a filtering request is required from an on-board charger, selecting a mode of a plurality of modes for driving a filter based on the signal instructing whether or not the filtering request is required, and charging a battery using the selected mode.
Claims20
A charging power filtering method, the method comprising:
- receiving a signal instructing whether or not a filtering request is required from an on-board charger;
- selecting a mode of a plurality of modes for driving a filter based on the signal instructing whether or not the filtering request is required, wherein the filter is connected in series or parallel to the on-board charger and wherein, when the filter is connected in series to the on-board charger, the plurality of modes comprises a filtering mode for removing a harmonic signal and a filtering stop mode for not removing the harmonic signal;
- and
- charging a battery using the selected mode.

A charging power filtering device, the device comprising:
- an AC power supply;
- an on-board charger configured to convert input power from the AC power supply into DC power;
- a filter configured to operate in a mode of a plurality of modes to remove a harmonic signal from the DC power, wherein the filter is connected in series or parallel to the on-board charger and wherein, when the filter is connected in series to the on-board charger, the plurality of modes comprises a filtering mode for removing the harmonic signal and a filtering stop mode for not removing the harmonic signal;
- and
- a battery configured to be charged by receiving power from which the harmonic signal is removed by the filter.
