We Provide EV Battery Reuse Solution When the capacity of the lithium battery used in electric vehicles is reduced to less than 70% of the initial capacity, the battery needs to be replaced due to problems in vehicle operation, such as reduced mileage, reduced charging speed, and increased safety risk. The battery after such replacement cannot be used again in passenger and commercial vehicles under the current law. Therefore, usable batteries are selected and re-commercialized so that they can be used in ESS (Energy Storage System) or special vehicles for limited use so that they can be used as the 2nd life of batteries.”
