GB/T 36282-2018: Electromagnetic compatibility requirements and test methods of drive motor system for electric vehicles

This standard specifies the electromagnetic compatibility requirements and test methods of drive motor system for electric vehicles. This standard applies to the drive motor systems of pure electric vehicles, hybrid electric vehicles and fuel cell electric vehicle. In this standard, it considers the HV (high voltage) power system component as a typical full shielding system. Note: Electric vehicle power systems are usually divided into two types: the first type is common LV (low voltage) system, its typical structural features are unshielded; and the second type is HV system, its typical structural features are shielded.

Electromagnetic compatibility requirements and test
methods of drive motor system for electric vehicles
1 Scope
This standard specifies the electromagnetic compatibility requirements and test methods of drive motor system for electric vehicles.
This standard applies to the drive motor systems of pure electric vehicles, hybrid electric vehicles and fuel cell electric vehicle.
In this standard, it considers the HV (high voltage) power system component as a typical full shielding system.
Note. Electric vehicle power systems are usually divided into two types. the first type is common LV (low voltage) system, its typical structural features are unshielded; and the second type is HV system, its typical structural features are shielded.

can be specified in the test report.
If the EUT contains multiple units, the connection line between the units shall use the connection harness used in the original vehicle; if this is not possible, the length of the connection line between the electronic control unit and the artificial power supply network (AN) shall be in accordance with this standard. The wiring harness shall be terminated as required and with actual load and excitation.
5.1.1.3 Test arrangement
The test layout is shown in Figure 3.
The shielding configuration shall be arranged in accordance with the actual situation of the vehicle. Normally all shielded HV components shall be grounded with low impedance (e.g. AN, cable, connector, etc.). Both the EUT and the load shall be grounded. Outdoor HV power supplies shall be connected via
feedthrough filtering.
The LV load simulator is arranged and grounded in accordance with 6.4.2.5 of GB/T 18655-2010, or grounded in accordance with the actual grounding
condition on the vehicle.
Unless otherwise specified, the length of the LV harness and HV harness parallel to the front end of the ground plane shall be 1500 mm ?? 75 mm, respectively. The length of the LV harness and HV harness (including
connectors) shall be mm, respectively. The HV test harness shall be
mm from the LV test harness.
All harnesses shall be placed on a non-conducting, low relative permittivity (??r ??? 1.4) material, 50 mm ?? 5 mm above the ground plane.
The HV positive power cable and the HV negative power cable can be single coaxial shielded cables or share the same shield. It is recommended to use the original HV harness for the vehicle. The three-phase line of the motor is also applicable to the provisions of this clause.
Unless otherwise specified, the EUT housing shall be connected to the ground plane either directly or through a specified impedance.
To avoid the effects of environmental noise, an environmental noise test shall be performed prior to testing. The ambient noise level shall be 6 dB below the limit.
Measurements shall be made in a semi-anechoic chamber with a frequency
range of 30 MHz ~ 1000 MHz.
Measurements shall be made under vertical polarization and horizontal
polarization of the antenna, respectively.
Measurements can be made using a spectrum analyzer or a scanning receiver. The measurement parameters shall be set in accordance with the provisions of GB/T 18655-2010.
To speed up the test, a peak detector can be used for scanning, but when the peak measurement exceeds the limit requirements in 4.1.1, a quasi-peak
detector shall be used for the final test.
5.1.2 Narrowband electromagnetic radiation emission test
5.1.2.1 Test method
The method is for testing narrowband electromagnetic radiation emissions produced by an EUT, such as a microprocessor-based system. If there is no other explanation, in the frequency range of 30 MHz ~ 1000 MHz, the test shall be carried out in accordance with the method specified in GB/T 18655-2010. 5.1.2.2 Test status
The HV and LV are powered normally, the EUT drive module is in standby mode with no output power.
5.1.2.3 Test arrangement
Same as the test layout requirements of 5.1.1.3, as shown in Figure 3.
5.1.2.4 Test requirements
Measurements shall be made in a semi-anechoic chamber with a frequency
range of 30 MHz ~ 1000 MHz.
Measurements shall be made under vertical polarization and horizontal
polarization of the antenna, respectively.
Measurements can be made using a spectrum analyzer or a scanning receiver. The measurement parameters shall be set in accordance with the provisions of GB/T 18655-2010.
5.2 Immunity test
5.2.1 Electromagnetic radiation immunity
The EUT shall be in normal operation with a speed of 50% of the rated speed, a torque of 50% of the rated torque, and a mechanical output load of 25% of the continuous power.
When the speed or torque does not reach the EUT test status, the torque or speed can be adjusted to achieve 25% of the continuous power, which shall be noted in the test report.
Note. When the power requirements are not met, the working status of the EUT can be specified in the test report.
5.2.1.3 Test arrangement
The big current injection (BCI) test layout is shown in Figure 4; the anechoic chamber (ALSE) test layout is shown in Figure 5.
Figure 5 only shows an example of the test arrangement of the horn antenna when the EUT is used above 1 GHz. The 200 MHz ~ 1 GHz frequency range
can be tested using a double cone antenna.
The shielding configuration shall be configured in accordance with the vehicle's series. Normally all shielded HV components shall be grounded with low
impedance (e.g. AN, cable, connector, etc.). The EUT and load shall be
grounded. Outdoor HV power supplies shall be connected via feedthrough
filtering.
Unless otherwise specified, the length of the LV harness and HV harness parallel to the front end of the ground plane shall be 1500 mm ?? 75 mm, respectively. The length of the LV harness and HV harness (including

vehicle can be selected for use.
All harnesses shall be placed on a non-conducting, low relative permittivity (??r ??? 1.4) material, 50 mm ?? 5 mm above the ground plane.
Unless otherwise specified, the EUT housing shall be connected to the ground plane directly. When it is connected to the ground plane through a specified impedance, it shall be indicated in the test report.
Unless otherwise specified, the injection probe is only placed on the LV harness for testing.
