Control of Battery Electric Vehicle using Modular Multilevel Converter

Abstract

Energy storage system is significant in (EV) electric vehicles. Several cells are usually connected in series in electric automobiles to improve motor power output voltage. Several electrochemical properties create the charging status (SOC) the difference between cells in battery. This paper refuges energy management and motor drives for electric automobiles using MMC. To adjust the state of the circuit of each battery cell. The following article offers an integrated electronic cell converter with MMC that produce exceptionally low cell discrepancies, without the requirement for traditional circuit balance or a low harmonic output current content. The semi-bridge cell interfaces in this new architecture make battery depletion and recharge very versatile. Included in the converter is a cell balancing control that interacts with cell load on every converter arm. Specific controls can substantially increase the energy usage of the battery depending on how much each cell charges. By utilizing a fuzzy logic controller, the total harmonic distortion may also be minimized. The investigation indicates that, even if the cells are considerably unbalanced, the proposed regulation has no influence on the symmetry of a three-phase voltage.
