# EVA

> Dunsky documentation for EVA: find model guidance, source references, and the right tools for your work.

EVA is Dunsky’s Electric Vehicle Adoption model. Use EVA for electric vehicle adoption modelling. Its package is maintained under `packages/eva`; the platform provides an EV Adoption & Load workflow with a run-type wizard.

## Use the model

For browser-based execution, open [models.dunsky.com](https://models.dunsky.com) and follow the [platform run guide](https://docs.models.dunsky.com/quickstart.md).

For local execution, start with the [package README](https://github.com/dunsky-consulting/packages/blob/trunk/eva/README.md). It documents the environment and installation steps; repository access is required.

After installing and configuring the package, its documented entry point is:

```bash theme={null}
eva --help
```

## Model notes

The package README distinguishes adoption and load run configurations. It also identifies IPOPT as a solver requirement for calibration. Follow the package’s complete installation procedure, including its solver step, before using the CLI.
