EVs offer larger storage potential for households compared to home batteries, with capacities ranging from 60 to 80 kWh in Sweden's common electric cars, surpassing the typical 10 kWh capacity of home batteries.
Higher storage capacity enables households to maximize self-produced solar power utilization, optimize consumption against spot prices, and provide support services on multiple markets.
Incentives for flexibility and storage must be enhanced to boost interest in Vehicle-to-Grid (V2G) technology.
Energy tax structures currently hinder V2G adoption by discouraging storage and favouring direct electricity use.
Bidirectional charging applications, focusing on using stored electricity locally, have been particularly appealing in Sweden.
V2G revenue opportunities include offering support services to the electricity system and participating in frequency regulation markets.
Aggregators play a crucial role in enabling small-scale resources like home batteries and electric cars to participate effectively in energy markets.
The aggregation of flexibility needs further improvement to incentivize electric vehicles to contribute to support service markets managed by Svenska kraftnät.
