**Abstract:** The special issue "Energy Storage Systems and Power Conversion Electronics for E-Transportation and Smart Grid" on MDPI *Energies* presents 20 accepted papers, with authors from North and South America, Asia, Europe and Africa, related to the emerging trends in energy storage and power conversion electronic circuits and systems, with a specific focus on transportation electrification and on the evolution of the electric grid to a smart grid. An extensive exploitation of renewable energy sources is foreseen for smart grid as well as a close integration with the energy storage and recharging systems of the electrified transportation era. Innovations at both algorithmic and hardware (i.e., power converters, electric drives, electronic control units (ECU), energy storage modules and charging stations) levels are proposed.

**Keywords:** electric vehicles (EVs); hybrid EV (HEV); plug-in EV (PEV); intelligent transport systems; renewable energy sources; battery; energy storage; electric machines; electric drives; electronic control unit (ECU); fast charging; smart grid; automotive electronics; power converters; Internet of Energy; Internet of Things (IoT)
