What is Electric Vehicles and Infrastructure?
Electric Vehicles and Infrastructure refers to the integration of electric vehicles into power systems through charging infrastructure, vehicle-to-grid technology, renewable energy integration, grid impact assessment, battery technology, consumer adoption strategies, smart grid interactions, life cycle assessment, and sustainability measures.
This field encompasses 88,347 papers on topics including vehicle-to-grid technology, charging infrastructure, and battery management for electric vehicles. Key works address grid impacts from charging and bidirectional power flow in chargers. Research also covers lithium-ion battery state estimation and equivalent circuit models for vehicle applications.
Topic Hierarchy
Research Sub-Topics
Vehicle-to-Grid Technology
Researchers develop V2G protocols for bidirectional power flow, battery degradation modeling, and grid service provision like frequency regulation using EV fleets.
EV Charging Infrastructure
This sub-topic optimizes charger siting, fast-charging topologies, load management, and smart scheduling to minimize grid congestion and user wait times.
Electric Vehicle Battery Management
Studies advance SOC/SOH estimation, thermal management, cell balancing, and fault detection algorithms using Kalman filters and machine learning for Li-ion packs.
EV Grid Impact Assessment
Researchers model power quality, voltage stability, harmonic distortion, and transformer loading from uncoordinated EV charging via Monte Carlo simulations.
EV Renewable Energy Integration
This area examines EV charging aligned with solar/wind generation, storage arbitrage, and sector coupling for decarbonizing transport and electricity.
Why It Matters
Electric vehicles and infrastructure enable grid stabilization and renewable energy support through vehicle-to-grid systems, as shown in 'Vehicle-to-grid power fundamentals: Calculating capacity and net revenue' (Kempton and Tomić, 2005) and 'Vehicle-to-grid power implementation: From stabilizing the grid to supporting large-scale renewable energy' (Kempton and Tomić, 2005), which quantify capacity and revenue for grid services. Charging plug-in hybrids impacts residential distribution grids, with 'The Impact of Charging Plug-In Hybrid Electric Vehicles on a Residential Distribution Grid' (Clement-Nyns et al., 2009) demonstrating increased losses and voltage deviations under unmanaged loads. Battery management addresses key issues like state of charge estimation, detailed in 'A review on the key issues for lithium-ion battery management in electric vehicles' (Lu et al., 2012), supporting reliable operation in vehicles. Charger topologies and power levels, reviewed in 'Review of Battery Charger Topologies, Charging Power Levels, and Infrastructure for Plug-In Electric and Hybrid Vehicles' (Yılmaz and Krein, 2012), facilitate infrastructure deployment for plug-in vehicles across off-board and on-board systems.
