The Development of Bidirectional Charging for Evs

Bidirectional charging is a crucial trend in the evolution of EVs, with three primary application types: Vehicle-to-Grid (V2G), Vehicle-to-Home (V2H), and Vehicle-to-Load (V2L). While V2G optimizes grid load balancing and power dispatch, it involves multiple endpoints. This not only necessitates bidirectional charging capability in the vehicles but also requires bidirectional V2G charging equipment, requiring collaboration with aggregator energy service providers and public power grids. Its application scope can be either broad or narrow. In contrast, V2H requires additional infrastructure, while V2L is solely vehicle-dependent, allowing the charging of small appliances via a built-in bidirectional charger (OBC), offering convenience during outdoor activities or work and is the fastest bidirectional charging application to implement.
