| description | With the increasing demand and reliance on Li-ion batteries, the importance of implementing a fast-charging solution grows simultaneously. As such, this project aims to help improve the fast-charging algorithm, Nonlinear Voltammetry (NLV). Taking into account optimal software designs and future improvements, we created a new application for thorough testing of this algorithm on a variety of batteries. This includes validating that the NLV algorithm outperforms the current industrial method called the Constant Current Constant Voltage (CCCV) algorithm.
After thorough battery testing, important algorithm variables (such as delta𝑉𝑉, maximum voltage, minimum cutoff current) were determined and their impact while ensuring temperature to ensure the preservation of the battery's health. The software that is produced follows important software design rules and includes safety features such as a kill switch and battery temperature limits set at 55°C. Battery tests involve utilizing the NLV algorithm on various types of lithium-ion batteries with different battery capacities to demonstrate its applicability.
Additionally, this project emphasizes the pressing necessity for more effective charging techniques to meet the demands of quicker charging solutions in areas such as power tools and electric vehicle batteries. This project highlights the potential widespread implementation of the NLV algorithm by highlighting its compatibility and impact on fast charging cells like the Samsung 30T and 40T, maintaining safety and performance standards. This project proves that a more adaptive and efficient approach to battery charging can be achieved without compromising safety and battery longevity |
