The Electric Vehicles (EV) adaptability is at the early stage in India due to many performances and commercial constraints among the potential customers. Battery Electric Vehicles (BEV) are slowly picking up in the Indian market and likely to grow due to stringent Government regulations and Green Mobility initiatives. The primary constraint in EV purchase is the driving range offered by Original Equipment Manufacturers (OEM) and EV range anxiety. This paper discusses the current battery pack integration among Indian Original Equipment Manufacturers (OEMs), design challenges, and the need for Standardised Battery Pack envelope (SBP). This study analyses the India OEMs vehicle data and, using a statistical and engineering assessment model, recommends the critical standard dimensions, type, size for the Standardised Battery Pack (SBP). This is possible by means of Electric Vehicle (EV) skateboard platform architecture, and platform sharing proliferate among EV manufacturers and start-ups. The model verifies the results by analytical and Simulation techniques. The results show the proposed model with SBP gives higher flexibility, improved driving range, convenient battery swapping operation, improved operation time, and helps in second-life applications. This study's limitation is that due to the rapid advancement in battery technology, a specific battery chemistry is under consideration throughout the study. © 2021 Elsevier B.V., All rights reserved.
