Point detail

The vehicle shall be in configuration "REESS charging mode coupled to the power grid". The state of charge (SOC) of the traction battery shall be kept between 20 per cent and 80 per cent of the maximum SOC during the whole frequency range measurement (this may lead to splitting the measurement in different sub-bands with the need to discharge the vehicle's traction battery before starting the next sub-bands).
If the current consumption can be adjusted, then the current shall be set to at least 80 per cent of its nominal value for AC charging.
If the current consumption can be adjusted, then the current shall be set to at least 80 per cent of its nominal value for DC charging unless another value is agreed with the type approval authorities.
In case of multiple batteries the average state of charge must be considered.
The vehicle shall be immobilized, the engine(s) (ICE and / or electrical engine) shall be OFF and in charging mode.
All other equipment which can be switched ON by the driver or passengers shall be OFF.
