Bidirectional EV charging interface
In plain English
What does Bidirectional EV charging interface mean?
A bidirectional charging interface supports controlled energy transfer in both permitted directions.
A simple example
A compatible installation can use vehicle energy to support another electrical system under its operating arrangement.
What the drawings help you do
Use arrows in both permitted energy directions and identify the controller authorising each operating mode. The vehicle, charger and connected system must support the intended exchange. Keep the energy path separate from communication and operating permission so hardware capability is not mistaken for permission to export.
- Bidirectional
- Capable of the specified transfer in two directions.
- Export
- Supplying energy from the vehicle-side system to the connected system.
Before using this reference
- Identify the intended charging and export modes.
- Show the compatible vehicle and system-control interfaces.
- Reference operating permissions and the complete selected equipment.
Can any bidirectional charger export to a public grid?
No. Hardware capability alone does not establish vehicle compatibility, an approved installation or permission to export. Those conditions must be confirmed for the selected system and location.

A distinction that matters
Bidirectional hardware does not by itself establish grid permission, compatibility or operating approval.
