For ESAs in configuration ‘REESS charging mode coupled to the power grid’ the test arrangement shall be according to Figure 2 of the appendix to this annex.
3.2.1.
The shielding configuration shall be according to the vehicle series configuration.
Generally all shielded High Voltage (HV) parts shall be properly connected with low impedance to ground (e.g.
AN, cables, connectors etc.).
ESAs and loads shall be connected to ground.
The external HV power supply shall be connected via feedthrough-filtering.
3.2.2.
The ESA power supply lead shall be connected to the power supply through an HV-AN (for ESA with DC HV supply) and/or AMN (for ESA with AC supply).
DC HV supply shall be applied to the ESA via a 5 μH/50 Ω HV-AN (see Appendix 8 clause 2).
AC supply shall be applied to the ESA via a 50 μH/50 Ω AMN (see Appendix 8 clause 4).
3.2.3.
Unless otherwise specified the length of the Low Voltage (LV) harness and the HV harness parallel to the front edge of the ground plane shall be 1,500 mm (±75 mm).
The total length of the test harness including the connector shall be 1,700 mm (+300/-0 mm).
The distance between the LV harness and the HV harness shall be 100 mm (+100/-0 mm).
3.2.4.
All of the harnesses shall be placed on a non-conductive, low relative permittivity material (εr ≤ 1.4), at 50 mm (±5 mm) above the ground plane.
3.2.5.
Shielded supply lines for HV+ and HV- line and three phase lines may be coaxial cables or in a common shield depending on the used plug system.
The original HV-harness from the vehicle may be used optionally.
3.2.6.
Unless otherwise specified, the ESA case shall be connected to the ground plane either directly or via defined impedance.
3.2.7.
For onboard chargers, the AC/DC power lines shall be placed the furthest from the antenna (behind LV and HV harness).
The distance between the AC/DC power lines and the closest harness (LV or HV) shall be 100 mm (+100/-0 mm).
3.3.
Alternative measuring location As an alternative to an absorber lined shielded enclosure (ALSE) an open area test site (OATS), which complies with the requirements of CISPR 16-1-4 may be used (see Figure 1 of the appendix to this annex).
3.4.
Ambient To ensure that there is no extraneous noise or signal of a magnitude sufficient to affect materially the measurement, measurements shall be taken before or after the main test.
In this measurement, the extraneous noise or signal shall be at least 6 dB below the limits of interference given in paragraph 6.5.2.1. of this Regulation, except for intentional narrowband ambient transmissions.
