摘要
An apparatus and method for compensating power of electrical load in a vehicle using a high-capacitance capacitor is provided. The high-capacitance capacitor rapidly discharges current to compensate power when voltage output from a generator and battery has temporarily dropped while the vehicle is traveling and the capacitor is charged in a constant power pulse charging manner to prevent battery voltage instability due to generator overload caused when the capacitor is charged. The capacitor is temporarily stopped from being charged and discharges current to compensate power of electrical load if terminal voltage of the battery is reduced due to the electrical load when the capacitor is charged, resulting in compensation of power supply instability such as voltage decrease in real time to improve vehicle output and to prevent temporary deceleration, thereby not only improving driving characteristics but also significantly increasing fuel efficiency and performance and lifespan of various electric parts.
