Evolving EVs as Mobile Storage Batteries
Electric vehicles, rapidly gaining popularity domestically, are transforming from mere transportation means into key components of energy management. With the emergence of V2X (Vehicle-to-Everything) technology, the future where over 1.3 million EVs function as virtual power plants is becoming increasingly realistic. This innovative system provides a new framework for flexibly utilizing the electricity stored in vehicles according to demand.
A Powerful Ally for Power Networks
During winter peak electricity demand periods, V2X-compatible vehicles will be able to supply power to homes and offices. The battery capacity of EVs owned by individual households typically ranges from 40kWh to 60kWh, sufficient to cover 2-3 days of electricity consumption for an average household. Particularly from evening to nighttime when solar power generation decreases, power transmission from EVs can contribute to stabilizing electricity supply.
Role as the Core of Smart Grids
V2X technology employs bidirectional charging systems, optimizing power flow according to circumstances. It enables dynamic power adjustment – charging during low-demand periods and discharging during high-demand periods. This allows power companies to benefit from efficient operation of existing transmission networks while reducing large-scale facility investments.
Economic Benefits for Users
EV owners will be able to generate income by charging during low electricity demand periods and selling power during high-demand periods. This mechanism not only helps reduce vehicle maintenance costs but also contributes to promoting renewable energy adoption. Particularly, it’s expected to play a role in absorbing output fluctuations from weather-dependent solar and wind power generation.
Challenges and Prospects for Practical Implementation
Currently, challenges remain for V2X widespread adoption, including charging infrastructure development and standardization of technical specifications. However, within a few years, major manufacturers are expected to successively release V2X-compatible models. Looking ahead, diverse applications are anticipated, including emergency power supply during disasters and community-wide energy sharing.
