# ElectricVehicleLoadEvent.Session

A session that tracks the event.

## Declaration

```swift
struct Session
```

## Overview

Overview A session starts when a device transitions from idle to consuming electricity. It’s active when consuming electricity. It ends when the device stops consuming electricity. A session must contain events of a single ElectricityFlowDirection. If a vehicle supports vehicle-to-grid (V2G), use a separate session for each direction.
