Abstract
In vehicle-to-grid(V2G),electric vehicles(EVs)can help regulate charging and discharging power and time slots,thereby assisting the power grid in peak shaving,accommodating renewable energy,and alleviating local congestion.The development of these technologies facilitates ecological synergy between EVs and the energy supply system.From the perspective of vehicle side in V2G,this paper analyzes key technologies including on-board hardware topology and dynamic response control,DC and AC interaction control,battery life degradation estimation,and user incentives.This paper also explores the driving forces and directions of these technologies and forecasts future technological trends.To address the challenges in current practice,including the lack of standardized AC charging pile hardware compatibility and protocols,the need for compatibility retrofits between new and legacy DC charging piles,insufficient development and application of user incentive technologies,unclear profit distribution rules,high vehicle costs,and the need to improve the operability of battery life assessment,this paper analyzes their current status and underlying causes.To promote the deployment of V2G,this paper provides recommendations in several areas,including the development of efficient and low-cost on-board hardware,the adaptation and compatibility of vehicle-charging pile hardware and communication systems,awareness guidance and service system design for battery life degradation,and the integration of artificial intelligence into user incentives.These recommendations are intended to serve as a reference for industry development.关键词
