Abstract: Disclosed herein is a battery discharge preventing system for a hybrid vehicle including a high voltage battery that drives a motor of the vehicle, a low voltage battery that supplies power to a black box, a first voltage sensor that measures a voltage level of the low voltage battery, a converter that charges the low voltage battery using the high voltage battery, a first relay that selectively regulates a current path between the high voltage battery and the converter, and a control unit that controls the first relay according to a measurement value of the first voltage sensor.

Abstract: A method and an apparatus control power of a vehicle including a main battery, an auxiliary battery, and an electric load. The Apparatus includes: a State Of Charge (SOC) detection unit configured to detect an SOC of the main battery and an SOC of the auxiliary battery, an allowable power calculation unit configured to calculate an allowable power of the main battery, a charging/discharging power calculation unit configured to calculate a charging/discharging power of the auxiliary battery, a first electric load power calculation unit configured to calculate a first electric load power, an operation control unit configured to control an operation of an electric load, a second electric load power calculation unit configured to calculate a second electric load power, and a charging/discharging control unit configured to control charging or discharging of the auxiliary battery.

Abstract: Provided is a method for fabricating a microstructure. The method includes disposing an X-ray mask on photosensitive material and exposing the photosensitive material by radiating X-rays to the photosensitive material, etching the exposed photosensitive material, forming a mold having a micro-pattern by filing the etched photosensitive material with metal, forming a mold module by combining a plurality of molds, and forming a microstructure using the mold module.
