Motor themes
EV and sustainabilityNeed for comprehensive models integrating sustainability metrics with infrastructure scalabilityPropose integrated frameworks for smart grid connectivity, renewable use and carbon reduction within EV infrastructure
Emerging/declining themes
ElectromobilityLimited empirical evidence from developing countries on stakeholder coordination and local governanceConduct multi-stakeholder case studies to evaluate electromobility deployment across local governance structures
Electric vehicles and barriersLack of integrated frameworks addressing socio-economic and policy-related adoption barriersFormulate multi-dimensional adoption models combining financial incentives, user education and infrastructure growth
Basic themes
Charging infrastructure and optimizationScarcity of unified multi-criteria optimization frameworks combining routing, energy sources and location strategiesDesign hybrid optimization models incorporating environmental, spatial and operational trade-offs at network scale
Electric vehicle chargingLack of coordinated frameworks combining user behavior, grid constraints and charging station dynamicsDevelop simulation-based decision tools to model interaction between user demand, grid load and infrastructure capacity
Charging stations and energy management strategyNeed for adaptive energy management strategies under varied operational contexts and emerging demand profilesExplore AI-driven adaptive scheduling and demand response models tailored for urban and rural energy ecosystems
Battery electric vehicle and electric mobilityInsufficient integration of BEVs in long-term strategic planning and limited life-cycle assessments in diverse regionsApply scenario-based modeling and dynamic LCA approaches to assess BEV deployment impacts in different regional contexts
