POWER MANAGEMENT METHOD USING BATTERY PACK FOR ELECTRIC VEHICLE

摘要

A method includes detaching a discharged battery pack for an electric vehicle, transporting the detached battery pack to a charging/discharging line, charging and storing the discharged battery pack, primarily checking a buffer capacity of the battery pack, classifying the battery pack as a buffer battery pack for replacement if the buffer capacity of the battery pack is found to be equal to or greater than a first buffer capacity, moving the battery pack to an energy storage-dedicated line if the buffer capacity of the battery pack is found to be smaller than the first buffer capacity, secondarily checking the buffer capacity of the battery pack, classifying the battery pack as an ESS-dedicated battery pack, discarding the battery pack if the buffer capacity of the battery pack is found to be smaller than the second buffer capacity, and converting power of the buffer battery pack and the ESS battery pack and sending the converted power.

主权项

1. A battery pack power management method for replacing a battery pack for an electric vehicle in a charging station S for charging or exchanging the battery pack, the method comprising:
a first step of detaching a discharged battery pack for the electric vehicle that has reached the charging station S; a second step of transporting the detached discharged battery pack to a charging/discharging line 150; a third step of charging and storing the discharged battery pack; a fourth step of primarily checking a buffer capacity of the battery pack; a fifth step of classifying the battery pack as a buffer battery pack 110 for replacement if, as a result of the check, the buffer capacity of the battery pack is found to be equal to or greater than a first buffer capacity; a sixth step of moving the battery pack to an energy storage-dedicated line if, as a result of the check, the buffer capacity of the battery pack is found to be smaller than the first buffer capacity; a seventh step of secondarily checking the buffer capacity of the battery pack; an eighth step of classifying the battery pack as an ESS-dedicated battery pack 120; a ninth step of discarding the battery pack if, as a result of the check, the buffer capacity of the battery pack is found to be smaller than the second buffer capacity by thirdly checking the battery pack; and a tenth step of converting power of the buffer battery pack 110 and the ESS battery pack 120 and sending the converted power.
