How to use battery packs for electric vehicles

Abstract

The present invention relates to a method for replacing, managing and delivering electricity using a battery pack replacement system for an electric vehicle with an energy storage system, managed in a system having both a battery pack replacement system for an electric vehicle and an energy storage system In terms of a method for a battery pack, it includes the steps of: removing the discharged battery pack from the electric vehicle; transporting the removed discharged battery pack to a charging / discharging line; charging the discharged battery pack and storage; check the buffer capacity of the battery pack once; if the buffer capacity of the battery pack is higher than the first buffer capacity reference, it is classified as a buffer battery pack for battery replacement; if the buffer capacity of the battery pack capacity is lower than the first buffer capacity benchmark, it is moved to an energy storage dedicated line; the buffer capacity of the battery pack is checked a second time; and the battery pack is classified as an ESS dedicated battery pack. The present invention charges and stores a plurality of battery packs, replaces the charged battery packs in storage with discharged battery packs, and installs them in the vehicle, thereby converting the existing method of charging directly by the driver into a replacement battery pack. The way, its effect is to reduce the safety accidents that occur during direct charging, compared with the time of direct charging, the replacement time is significantly reduced, and time can be saved.

Description

technical field [0001] The present invention relates to a method of using a battery pack for an electric vehicle, the battery pack for an electric vehicle is constituted by replacing a discharged battery pack of the electric vehicle with a charged battery pack, and The battery packs are sorted into those for replacement and those for storage, and are kept so that they can deliver power when necessary. Background technique [0002] The acceleration of the global warming effect, the occurrence of meteorological disasters and severe climate change are threatening people's lives. In this regard, the whole world is issuing a strong call to limit carbon dioxide. According to the above environmental and social needs, the automobile industry is ushering in a new situation, and as a part of it, environmentally friendly vehicles are receiving more and more attention. The environmental protection Automobiles are capable of minimizing exhaust emissions from internal combustion engine v...
