Document Type and Number:
WIPO Patent Application WO/2015/102151
Kind Code:
A1
Abstract:
The present invention relates to a power management method using a battery pack for an electric car. The present invention is directed to a method for replacing a battery pack for an electric car at a charging station for charging or replacing the battery for an electric car, comprising: a step of removing a discharged battery pack of an electric car which has arrived at the charging station; a step of carrying the removed, discharged battery pack to a charge and discharge line; a step of charging and storing the discharged battery pack; a step of firstly checking the buffering capacity of the battery pack; a step of classifying the battery pack as a buffer battery pack for replacing a battery when the buffering capacity of the battery pack is higher than a first buffering capacity; a step of moving to an energy storage dedicated line and performing classification when the buffering capacity of the battery pack is lower than the first buffering capacity; a step of secondly checking the buffering capacity of the battery pack; a step of classifying the battery pack as an ESS dedicated battery pack; a step of thirdly checking the battery pack and discarding when the buffering capacity of the battery pack is equal to or less than the secondly checked buffering capacity; and a tenth step of converting the buffer battery pack and the ESS battery pack into power and transmitting power. The present invention charges and stores a plurality of battery packs, thereby ensuring stable backup power, transmission of power to the state or state-designated authorities, and efficient use of electrical energy. Thus, the present invention has an advantage of being able to contribute to national energy saving.
