A bidirectional converter allows two-way converter enables electrical current to circulate both ways — from the grid to the EV (charge), and from the EV to the grid (discharge). Two-way capability opens up new energy opportunities.
How Do They Work in EVs and Energy Storage Systems?
In EVs, these converters provide Vehicle-to-Grid (V2G) or Vehicle-to-Home (V2H) capabilities. In energy storage, they serve as a switchboard, determining when to store or discharge energy according to grid demand.
Role of Bidirectional Converters in EVs
Vehicle-to-Grid (V2G) Explained
With V2G, your EV is essentially a mini power station. Under peak demand, it can supply energy back to the grid, mitigating pressure and paying you in credits or dollars.
Vehicle-to-Home (V2H) Applications
Pever experienced a power outage? With V2H, your EV can energize your home when outages occur — in effect, a quiet, pollution-free backup generator.
Improving Battery Efficiency and Longevity
Both modern bidirectional converters control energy flow with high precision, minimizing wear and tear on batteries and extending their life by preventing overcharging or deep discharging.
Role in Energy Storage Systems
Supporting Renewable Energy Sources
Wind and solar are not constant. Bidirectional converters enable efficient energy transfer from sources, batteries, and loads — leveling the supply curve.
Grid Balancing and Load Management
Power demand changes throughout the day. Energy storage systems with bidirectional converters help balance the load, avoiding blackouts and reducing grid reliance on fossil fuels.
Enhancing Resilience in Power Outages
From California wildfires to Indian monsoons, power cuts are real. Bidirectional converters paired with storage systems provide decentralized, reliable power even when the grid fails.
