For: Operators using Monta Hub.

Use the page to inspect what happened during a charge, stop a live session, issue a refund, or troubleshoot.

How do I open a charge session?

1. In the left-side menu, select Charging sessions.
2. Select any row in the list. 

Session alerts

If the session has any active alerts — for example, a payment retry in progress, a known dispute, or a configuration warning — they appear in a banner just below the breadcrumbs. Each alert has a title and a description, and is colour-coded by severity (info, warning, success, error). Alerts disappear automatically when the underlying condition is resolved.

What does the status banner tell me?

A coloured stripe at the top of the page summarises the current state of the session:

• Charging — the session is in progress. A pulsing Live badge appears, together with a running clock that ticks every second in hh:mm:ss format, showing time elapsed since the session started.
• Pending / Starting / Stopping — the session is transitioning. The EVSE hasn't confirmed the action yet.
• Completed / Stopped — energy was delivered and the session has settled.
• Cancelled — the session ended before any energy was delivered.
• Failed — the session ended in error. The reason is shown below the status.

If the session is a test or simulated session, a Simulated badge appears, and you can select Edit fixture to change the test data.

Which actions can I take on a session?

The action bar in the top-right adapts to the session:

• View charge point — opens the related EVSE detail page. Visible when the session is linked to an EVSE.
• Open in Monta control — opens the same session in Monta Control in a new tab.
• View receipt — opens the session receipt as a PDF in a new tab. Visible only when a receipt has been issued.
• Refund — opens the refund dialog. Visible only when the transaction is refundable.
• Stop charge — stops the session immediately. Visible only while the session is active. You'll be asked to confirm before the stop is sent to the EVSE.

What do the hero KPIs show?

A row of cards at the top of the page surfaces the most important numbers (KPIs):

• Energy delivered — kWh delivered so far. If the session has a kWh limit, the percentage used and the limit are shown below.
• Duration — total elapsed time between session start and stop. For active sessions (charging, paused, starting, or stopping) it counts up live, so the card stays in sync with the running clock in the status banner instead of showing a blank.
• Avg power — average power across the session, calculated from delivered kWh and duration.
• Price — what the driver pays. Includes price per kWh.
• Cost — what the charge actually cost (electricity + fees). Includes cost per kWh.
• Margin / Loss — difference between price and cost. Shown as Margin when positive and Loss when negative, with the percentage in brackets. The per-kWh delta is shown beneath.

The cost and margin cards appear only when you have permission to view team and price-group cost data.

What's in the session context strip?

Below the headline numbers, a metadata strip shows the infrastructure chain and the session context:

• Infrastructure chain: EVSE → location → team → operator. Each segment is a selectable link when available.
• User: name of the driver. Hover the name to open a popover with contact details (email, phone) and lifetime stats (total charges, total energy). When the driver is a Monta user, the name at the top of the popover is a link through to the user detail page; for roaming or OCPI sessions where the driver isn't a Monta user, the name stays as plain text.
• Start source: how the session was started — Plug and Charge, RFID, Instant, Auto-start, Scheduled, Smart charge, Mobile app, Remote, or API. Hover to see a tooltip explaining the source and the raw API value.
• Vehicle: the registered vehicle for the session, if known.

Select View details to expand additional metadata, including payment method and other identifiers.

The rest of the page is organised into three tabs:

• Overview — full session breakdown (default).
• Logs — station logs from the EVSE during the session. Only enabled when an EVSE serial number is present.
• Custom fields — partner custom payload values attached to the session. Editable.

Overview tab

The Overview tab contains all the session detail cards.

Session telemetry (charge curve)

The Session telemetry card visualises how power, energy, and other meter values evolved across the session. When per-sample meter data is available, the card shows two tabs at the top:

• Telemetry — a continuous line chart of meter readings sampled during the session. Toggle the metrics you want overlaid:
  • Power (kW)
  • Energy — cumulative kWh delivered
  • Current — amperes
  • Voltage
  • State of charge (SOC) — vehicle state of charge, when reported by the charge point
• Consumption — an hourly bar chart of kWh delivered per hour, useful for comparing against tariff windows.

When no per-sample telemetry is available, the Telemetry tab is hidden and the card shows the Consumption view directly. If the session has no hourly readings either, the chart falls back to a two-point linear approximation drawn from the charge record and a note explains that per-sample meter values weren't captured.

Schedule

The Schedule card explains how the session got its start/stop times. Sessions use one of three mutually exclusive modes — the card adapts to whichever applies:

• Native — a fixed schedule the driver or operator pushed to the charge point. Renders as a slim Schedule start → Schedule stop bar with the duration in the middle. If a Start after time was set (the session won't begin before this timestamp), it's shown in a separate row.
• Smart charging — a Monta-optimised charge that picks the best window inside an earliest-start / latest-complete envelope. The card shows:
  • Charging window — a horizontal timeline with Earliest, Calculated (the actual chosen start), and Latest markers. The blue segment represents the charging window; any grey lead-in represents waiting time before the EVSE begins delivering energy.
  • Energy & power — a bar showing Start kWh → Stop kWh, with a Max kW chip on the right.
  • Priority mix — a donut chart of the three priorities used by the optimiser: Price, CO₂, and Renewable. The dominant priority's percentage is shown in the centre. A Green charging badge appears in the header when Renewable is the dominant priority.
  • Last recalculated — when the optimiser last re-ran the plan (for example, after an energy-price update).
• Charge profile — an Open Charge Point Protocol (OCPP) ChargeProfile pushed to the charge point by the server (usually via a subscription). The schedule is enforced by the charge point itself; raw profile details aren't exposed on this view.

Reservation

Shown when the session was preceded by an EVSE reservation. Displays the reservation fee, the reserved duration, and the expiry time. While the reservation is active you'll see when it expires; once it ends, you'll see when it expired.

Price breakdown

An invoice-style breakdown of how the final price was calculated. Numbered line items are grouped by tariff window (for example, off-peak versus peak), with fees and adjustments in their own sections and a totals stack at the bottom.

When value-added tax (VAT) applies to the session, a With VAT / Without VAT toggle lets you switch the displayed amounts between gross and net.

When cost data is available and you have permission to view it, a Cost breakdown tab is shown alongside the price breakdown. When a discount or promotion code was applied, a Discount tab shows the promotion, the discount percentage, the discount amount, and the amount Before discount.

How do I view the cost breakdown of a session?

1. Open the charge session you want to inspect.
2. Go to the Overview tab.
3. Scroll to the Price breakdown card and review the per-kWh rate, fees, and final price.
4. To switch between gross and net amounts, toggle With VAT / Without VAT.
5. If a Cost breakdown tab is shown, select it to compare price against actual cost.

Expected result: the per-kWh rate, fees, adjustments, and final price are visible, with VAT toggled to your preferred view.

Split billing

Shown only for sessions paid by a team with a kWh price cap. Displays:

• Effective kWh rate — the rate actually charged.
• Covered rate — the part covered by the team.
• Team share — the team's portion of the total amount.
• Driver contribution — what the driver paid on top.

Each value has a tooltip explaining how it was calculated. 

Timeline

The session lifecycle, shown as a vertical timeline. Each milestone has a coloured icon that matches the status:

• Created — the session was registered.
• Starting — start request sent to the EVSE.
• Charging — energy flow began. The active milestone glows softly.
• Stopping — stop request sent.
• Stopped — energy delivery ended cleanly.
• Completed — the session is settled.
• Failed — the session ended in error. The failure reason is shown below the milestone.
• Released — the connector was released.

Hover any milestone to see the description, the duration spent in that state, and any micro-transitions that occurred before the next milestone.

Driver rating

If the driver rated the session in Monta Charge, the rating is shown here together with any comment and the platform the rating was submitted from.

Impact report

Estimated environmental impact of the session:

• Estimated CO₂ saved vs fuel — kg of CO₂ avoided compared to a fossil-fuel equivalent journey.
• Estimated CO₂ emitted — kg of CO₂ from the grid mix at the time of charging.
• Estimated electricity vs fuel cost savings — money saved versus refuelling a comparable car.

Logs tab

The Logs tab shows the raw OCPP message log for the charge point covering the session. Each row includes a timestamp, the message direction (charge point → server or server → charge point), the OCPP action (for example, StartTransaction, MeterValues, StatusNotification, StopTransaction), and the message payload. The default date range matches the session start and stop times; widen it to investigate events just before or after the session. The tab is only available when the EVSE serial number is known — for roaming sessions (where the charge point belongs to another network) no logs are reachable.

Verification tab

The Verification tab appears when the verification feature is enabled and the session has odometer readings or detector flags. Alongside the tab itself, a Verification strip appears at the top of the Overview tab summarising the winning odometer reading and any open flag counts. Select the strip to jump straight to the tab.

The Verification tab contains three cards:

• Odometer — odometer readings collected during the session, grouped by source (driver-entered, telematics, OCR). The card highlights the winning reading used for compliance and indicates any disputes.
• Vehicle telemetry — snapshots captured from the linked vehicle integration at session start and stop. Shows odometer (km), state of charge (%), and GPS location at each phase, plus the deltas across the session. The Start and Stop location values are selectable links — select either to open a dialog with the GPS coordinates, the time the reading was taken, and an interactive map pin at that point. The Delta column shows the straight-line distance between the two GPS points (in km or mi depending on the charge point's country), so you can see how far the vehicle moved between session start and stop. When the vehicle isn't linked to a telematics provider, the card shows an empty state.
• Detector flags — computed signals raised by the verification detectors, grouped by category (Fraud detection, Compliance, Vehicle assignment, Data quality). Each flag has a severity badge (info, warning, critical). Select Resolve to clear a flag from the queue with a reason.

Custom fields tab

Lists the partner custom payload attached to the session. Editable: change a value and Save to update the session record. Useful for partners that push their own metadata into Monta via API.

How do I stop a live session?

1. Open the live charge session from Charging sessions.
2. In the action bar, select Stop charge.
3. In the confirmation dialog, select Stop charge again to confirm.

Expected result: the stop request is sent to the EVSE. The status updates to Stopping and then to Stopped once the EVSE confirms. If the stop fails (for example, the EVSE is offline), an error message is shown and the session remains active.

How do I refund a session?

1. Open the session you want to refund from Charging sessions.
2. In the action bar, select Refund. The button is only available when the transaction is refundable.
3. Confirm the refund amount and currency in the dialog. By default the full transaction amount is pre-filled.
4. Select Submit.

Expected result: the refund is processed against the original payment source.
