Charging.Mode:

type: actuator
allowed: ['MANUAL', 'TIMER', 'GRID', 'PROFILE']
description: Control of the charge process.
allowed: ['DEACTIVATED', 'AUTOMATIC', 'TRIGGERED', 'TIMER', 'PROFILE', 'EXTERNAL_ENTITY', 'MANUAL', 'GRID']
description: Describes how the charging process is controlled.
DEACTIVATED means that charging and discharging is deactivated, nothing will happen if charger is connected.
AUTOMATIC means charging will be initiated as soon as charger is connected.
TRIGGERED means charging will be initiated when triggered by user.
TIMER means charging is timer-based.
PROFILE means charging is controlled by profile downloaded to vehicle.
EXTERNAL_ENTITY means charging/discharging is controlled by the external entity connected to the vehicle.
This includes GRID-controlled charging (e.g. ISO 15118), but also other cases where vehicle is
connected to an arbitrary load that is powered by the vehicle.
MANUAL means manually initiated (plug-in event, companion app, etc).
TIMER means timer-based.
GRID means grid-controlled (e.g. ISO 15118).
PROFILE means controlled by profile download to vehicle.
comment: The mechanism to provide a profile to the vehicle is currently not covered by VSS.
deprecation: V4.1 - MANUAL and GRID are deprecated, please use AUTOMATIC/TRIGGERED or EXTERNAL_ENITY instead.

Added MANUAL+GRID plus this deprecation text. Note that we here use the deprecation keyword in a somewhat new meaning as the signal itself is not deprecated but rather certain parts of it. We could alternatively just mention deprecation in free text

comment: EXTERNAL_ENTITY is the only mode where discharge may occur.
The mechanism to provide a profile to the vehicle is currently not covered by VSS.
