"REESS charging mode" ESA test conditions Failure criteria
ESA 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 split the measurement in different sub-bands with the need to discharge the vehicle's traction battery before starting the next sub-bands).
If the test is not performed with a REESS the ESA should be tested at rated current. If the current consumption can be adjusted, then the current shall be set to at least 20 per cent of its nominal value. 
Incorrect charging condition
(e.g. over-current, overvoltage)
