Technical FAQs 4

Can bidirectional charging overwhelm the grid?

If too much energy flows back at the wrong time, it can overwhelm the grid — similar to what happens when there’s an excess of solar power. That’s how bidirectional charging may introduce the need for grid expansion. To avoid this, V2G needs clear guidelines on when energy can and cannot be sent back to the grid.

Do I need a dedicated bidirectional charging unit?

For V2H and V2G bidirectional charging, a dedicated bidirectional charging unit is needed. The charger is designed to convert the DC power from the EV battery back to AC power, which can be used to power a home or send electricity back to the grid.

Why do EV batteries need bidirectional charging?

This can result in economic benefits for customers and help avoid overloading the energy supply grid. In contrast, bidirectional charging enables an EV battery to both receive and deliver energy to and from an external power source, making it a more flexible and efficient use of the battery.

What is vehicle-to-grid bidirectional charging?

Grid integration and expansion Vehicle-to-grid bidirectional charging allows electric vehicles to send energy back to the power grid when needed, helping balance supply and demand. This flexibility can be valuable, but it also needs careful management.
