Advancing EV Mobility : The Role of Portable Charging Solutions in Sustainable Transportation

Abstract

This chapter explores how portable charging solutions for electric vehicles (EVs) can bridge important infrastructure gaps in the transition toward sustainable mobility. Widespread EV adoption is accelerating nowadays due to environmental concerns and government policies, but there are challenges such as range anxiety, unequal infrastructure distribution, and high costs, which act as a barrier to widespread adoption. The chapter introduces the different portable charging technologies, such as mobile charging stations, battery swap systems, solar-powered kits, and EV-to-EV chargers, as an alternative to fixed charging stations. These solutions provide flexibility, accessibility, and emergency support, especially in underserved areas or during public events. A detailed technical and comparative analysis is conducted on five prominent portable chargers available in the market: FreeWire Mobi Charger, Kempower Movable Charger, EVgo Portable Charger, SparkCharge Roadie, and Blink Mobile Charger. Using a multi-criteria sensitivity analysis, FreeWire’s Mobi Charger ranks highest overall due to its high-power output, internal battery backup, and urban flexibility.

The analysis highlights the importance of mobile chargers to meet the real-world deployment needs in terms of being grid independent, modular, and second-life battery reuse, which contributes to the sustainability of the environment. However, there are some challenges like cost, infrastructure gap, and regional regulatory fragmentation. Policy standardization, investment in renewable integration, and public awareness are key elements to scale these solutions. The chapter concludes that portable chargers are not just temporary fixes but are crucial in achieving net-zero goals. They have the capability of supporting logistics, rural accessibility, and smart energy grids, as well as facilitating the practice of circular economy. Portable EV charging will form part of future urban mobility and climate action plans as it will continue to become more innovative, regulatory aligned, and invested in.
