METHOD OF USING BATTERY PACK FOR ELECTRIC VEHICLE
First Claim
1. A method of managing battery packs in a system equipped with a replacement system for replacing a battery pack for an electric vehicle and an Energy Storage System (ESS), the method comprising:
- a tenth step S10 of detaching a discharged battery pack 100 from the electric vehicle;
an eleventh step S11 of delivering the detached discharged battery pack 100 to a charging/discharging line;
a twelfth step S12 of charging and storing the discharged battery pack 100;
a thirteenth step S13 of primarily checking a buffer capacity of the battery pack 100;
a fourteenth step S14 of classifying the battery pack 100 as a buffer battery pack 100 for replacement if, as a result of the check, the buffer capacity of the battery pack 100 is equal to and greater than a first buffer capacity reference;
a fifteenth step S15 of moving the battery pack 100 to an energy storage-dedicated line if, as a result of the check, the buffer capacity of the battery pack 100 is smaller than the first buffer capacity reference;
a fifteenth-first step S15-1 of secondarily checking the buffer capacity of the battery pack 100; and
a sixteenth step S16 of classifying the battery pack 100 as an ESS-dedicated battery pack 120.

Abstract
Disclosed herein is a method of replacement, management, and power transmission using a battery pack replacement system for an electric vehicle with an ESS. The method includes detaching a discharged battery pack from the electric vehicle, delivering the detached discharged 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, as a result of the check, the buffer capacity of the battery pack is equal to and greater than a first buffer capacity reference, 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 smaller than the first buffer capacity reference, secondarily checking the buffer capacity of the battery pack, and classifying the battery pack as an ESS-dedicated battery pack.

5. A method of using a battery pack 100 for an electric vehicle in a system equipped with a replacement system for replacing the battery pack for the electric vehicle and an Energy Storage System (ESS), the system comprising:
-
a determination unit for determining a type of battery pack 100 of the vehicle; a replacement unit for detaching a discharged battery pack 100 from the vehicle or mounting a battery pack on the vehicle; a charging/discharging unit for charging/discharging and storing the discharged battery pack 100; and a transfer unit for conveying the discharged battery pack, detached from the replacement unit, to the charging/discharging unit or conveying the battery pack 100, charged by the charging/discharging unit, to the replacement unit, the method comprising; a thirty-first step S31 of comparing an amount of power of ESS battery packs 110 with an amount of power to be transmitted when the amount of power to be transmitted that is necessary for an emergent power supply is assigned by a nation power management institution; a thirty-second step S32 of assigning some of the ESS battery packs 110 and the buffer battery packs 120 if, as a result of the comparison, the amount of power of the ESS battery packs 110 is insufficient; and a thirty-third step S33 of converting power of a plurality of the ESS-dedicated battery packs 120 and a plurality of the battery packs for battery 110 that are charged and stored and sending the power according to the assigned amount of power. - View Dependent Claims (6, 7, 8)
