The present invention relates to a charging device of an electric road garbage vehicle. The charging device comprises: an on-board charging unit that converts external power to charge a high voltage battery; and a low voltage DC converting unit that converts power of the high voltage battery to charge or supply a low voltage battery to a load. The low voltage DC converting unit comprises: a first filter for stabilizing a DC voltage of the high voltage battery; a power converting unit for converting the stabilized DC voltage of the high voltage battery into a low voltage; and a second filter for stabilizing the low voltage of the power converting unit.
