EV Charger

Get EV Charger charging sessions

Session history depends on the charger. Read sessions on GET /ev-charger/{deviceId} first: false means the manufacturer records none and this endpoint answers 422 SESSIONS_NOT_SUPPORTED.

Returns this charger’s charging sessions, newest first. A session is one plug-in-to-completion episode; measurement states how energyDelivered was arrived at, so a caller billing against the figure can tell a metered reading from an integrated estimate. No measurement value is a settlement-grade guarantee.

Paged with the usual limit/offset.

Path Parameters

deviceId

string

required

The unique identifier for the EV Charger device.

Example:

"device_abc123"

Query Parameters

offset

integer

default:0

Number of sessions to skip (default: 0).

Required range: x >= 0

limit

integer

default:10

Maximum number of sessions to return (1-50, default: 10).

Required range: 1 <= x <= 50

status

enum<string>

Filter to sessions still running (active) or finished (completed).

Available options:

active,

completed

string

Only report sessions overlapping up to this instant (ISO 8601 UTC). Defaults to now.

Example:

"2026-07-30T00:00:00.000Z"

from

string

Only report sessions overlapping this instant onwards (ISO 8601 UTC). Defaults to 30 days before to.

Example:

"2026-07-01T00:00:00.000Z"

Response

Charging sessions retrieved successfully.

success

boolean

required

Always true for success responses.

data

EV Charging Sessions · object

required

A page of charging sessions, newest first. A session is one plug-in-to-completion episode; measurement states the provenance of energyDelivered, so a caller can tell a metered reading from an integrated estimate. Provenance is not accuracy: no measurement value promises a settlement-grade figure.

meta

Response Meta · object

required

Metadata attached to every response: the request identifier, the serving environment, the build timestamp, and the server-side latency.
