# chargingFormulaArguments

The parameters the electric vehicle’s charging model uses to calculate the duration of a charge.

```
var chargingFormulaArguments: [String : Any]? { get set }
```

## Discussion

This property’s value is a dictionary of serializable objects that contains the parameters the electric vehicle’s charging model uses to calculate the duration of charge at a charging point. The keys of the dictionary must match those of the corresponding charging model. `model_id` is a mandatory key and must be the identifier of the charging model the vehicle uses.
