As the driving range and performance of electric vehicles increase, consumers are becoming interested in electric vehicles. This predicts that countless reusable or recycled batteries will be released from electric vehicles in the future, which means that the remaining capacity of the battery must be tested to distinguish between reuse and recycling of the battery. Accordingly, this paper proposes a battery testing method that can quickly estimate the remaining capacity of a reused/recycled lithium-ion battery.
This study models a reused battery based on a secondary RC network model, extracts parameters to construct a simulation, compares the charge/discharge graph of an actual battery to confirm the effectiveness of the battery model, and compares the charge/discharge graph of the actual battery to confirm the linear The feasibility of the proposed method was confirmed by selecting a section and predicting the remaining capacity of the battery through pulse charging and discharging in the linear section.
