What Is Bidirectional or Two-Way Charging?

Bidirectional or two-way charging allows your electric vehicle to receive and supply electrical current.

The primary purpose of bidirectional EV charging is to supply electricity to your home during an outage.

This means you’re free to use an EV with bidirectional charging to reduce your electricity bill significantly.

But if you frequently experience power interruptions, consider getting somemust-have devices when the power goes out.

Which EVs Have Bidirectional Charging?

Not many electric vehicles currently have V2H or V2G systems.

If you own a Nissan Leaf, you’re required to install a Fermata Energy FE-15 charger.

Similarly, if you own the F-150 Lightning, you must install a V2H bidirectional charging system fromSunrun.

V2V bidirectional charging is also expected to be one of thefeatures of the Tesla Cybertruck.

How Long Could an EV With Bidirectional Charging Power My Home?

If you reduce high power consumption devices in your home, it could discharge in up to 10 days.

On the other hand, the Nissan Leaf has a battery capacity of 40kWh and 62kWh.

How long your EV battery lasts depends on the power consumption of your electrical appliances.
