A charge intent defines how a charging session should behave — whether to charge immediately at full power, optimise for the cheapest energy prices, or target a specific State of Charge by a departure time.

Charge intents can be set at different levels — site, RFID key, vehicle, or EVSE — and the system automatically applies the most relevant one when a session starts.

Intent types

Site default intent

The site default is the fallback intent for any session where no more specific rule matches. Every site should have one configured.

Good defaults to start with:

• Charge Now — charge at maximum available power immediately
• Price Optimise — charge at the cheapest hours within the site's constraints

RFID intent

An RFID intent is tied to a specific charge key. When a driver presents that key at any EVSE on the site, the associated intent is used for that session. Use RFID intents when individual drivers or vehicles have different charging requirements.

Vehicle ID intent

A vehicle intent is tied to a specific vehicle. It applies when that vehicle is identified — either via a connected integration or IEC 15118-2 communication. Vehicle intents are useful for fleet deployments where vehicles have specific energy needs or departure schedules.

EVSE intent

An EVSE intent is attached to a specific charge point. It applies to any session at that charger unless overridden by a more specific (RFID or vehicle) intent.

Priority resolution order

When a session starts, the system checks intents in this order and uses the first match:

App → RFID → Vehicle ID → EVSE → Site default

The App intent refers to a driver-set preference via the Monta app.

Scheduled overrides

Any intent can include a weekly schedule — different charging behaviour for specific days and time windows. For example:

• Weekdays 07:00–22:00: Price Optimise
• Weekdays 22:00–07:00: Charge Now (high capacity available, flat tariff)
• Weekends: Charge Now

Creating a schedule rule

1. Open the intent you want to edit
2. Go to the Schedule tab
3. Drag on the weekly grid to create a time window
4. Choose Charge Now or Price Optimise for that window
5. Save

Priority levels

When multiple EVSEs are competing for limited capacity, priority levels determine the charging order. Higher priority sessions receive power first.

Charge intent types

• Charge Now — charges immediately at the maximum power allowed by the node limits
• Price Optimise — optimises the charging schedule against day-ahead spot prices, respecting all node constraints and any departure time set
