The present invention relates to an electric vehicle and a charging control method for a battery thereof. An electric vehicle having a high-voltage battery which supplies driving power to a plurality of electric field loads comprises: a charger which is connected with an external power source to charge the high-voltage battery; a vehicle control module (VCM) which controls connection between the charger and the high-voltage battery; a battery management system (BMS) manages the state of the high-voltage battery according to the charging of the high-voltage battery or the supply of operating power from the high-voltage battery; and a voltage detection unit which detects and reports the charged state of the high-voltage battery to the battery management system, wherein the charger comprises a charger control unit, which controls to perform a power saving mode to minimize power consumption by interrupting the transmission of a driving signal for driving of the vehicle control module and battery management system when the charging of the high-voltage battery has been completed. Accordingly, even though the electric vehicle is left as it is after having been fully charged, the high-voltage is automatically charged, which makes it possible to stably operate the electric vehicle system.

An apparatus for continuously supplying fine particles (powder) in minute and quantitative amounts in a dispersed manner, is disclosed. An orifice throat 5 is formed in an orifice tube, and a powder carrying tube 7 is connected to the orifice throat. A powder suction tube 9 having a shape of an inverted funnel extends to the powder carrying tube, and a plurality of holes 16 are formed on a tapered circumferential surface of the powder suction tube 9. A powder storing container 10 closely contactedly receives the powder suction tube 9 in an air-tight state, but allows the powder suction tube to perform straight movements. A carrying system raises the powder storing container at a constant velocity, and a compressed gas injecting channel is connected to an upper portion of the powder storing container. A gas spouting nozzle 4 is connected to a compressed gas source, for spouting a compressed gas into the orifice throat 5 so as to form the powder into an aerosol. The fluidizing of the powder can be adjusted by adjusting the flow rate of the compressed gas (flowing through said compressed gas injecting channel 8), and the fluidizing of the powder is maintained at a constant level by raising the powder storing container at a constant velocity, so as to supply the powder quantitatively and continuously in a dispersed manner by forming an aerosol.
