Changes, Voltage Fluctuations and Flicker in Public Low-voltage Supply Systems, for
functions cannot be simultaneously configured, then, they need to be separately tested.
During the emission measurement, under the typical application and actual installation
conditions specified by the manufacturer, the electrical self-balancing vehicle shall be
measured under the operating state that generates the greatest disturbance at the
measurement frequency.
If the electrical self-balancing vehicle has auxiliary equipment, then, the electrical self-
balancing vehicle shall be connected to the least number and representative auxiliary
equipment of the application port during the operation test.
If the manufacturer requires external filtering and / or shielding devices or has
prescribed measures in accordance with the user manual, then, the test in this
document shall be carried out with the prescribed devices and measures, and the
specific devices and measures shall be clarified in the test report.
4.4 Test Environment
The tests shall be carried out in a designated environment, so as to ensure the correct
operation of the EUT. The following shall be adopted:
a) Ambient temperature: 15 °C ~ 35 °C;
b) For the electrostatic discharge immunity test, the relative humidity range is 30%
~ 60%; for other tests, the relative humidity is not greater than 75%;
c) Air pressure: 86 kPa ~ 106 kPa;
d) For the site of the radiated emission measurement, the requirements for semi-
anechoic chamber or open test field shall comply with the stipulations of GB/T
6113.104.
If the electrical self-balancing vehicle cannot normally function under the above-
mentioned environmental conditions, it may be tested in accordance with the operating
environment required by the manufacturer, and the environmental conditions of the
actual operation shall be recorded in the test report.
5 Emission
5.1 Conducted Emission
5.1.1 Requirements for conducted emission
The electrical self-balancing vehicle shall:
a) Simultaneously satisfy the specified average value limit when using the
average reading detector for measurement and the specified quasi-peak limit
GHz;
---If the highest internal operating frequency of the electrical self-balancing vehicle
is 108 MHz ~ 500 MHz, then, the measurement shall only be carried out to 2
GHz;
---If the highest internal operating frequency of the electrical self-balancing vehicle
is 500 MHz ~ 1 GHz, then, the measurement shall only be carried out to 5 GHz;
---If the highest internal operating frequency of the electrical self-balancing vehicle
is higher than 1 GHz, then, the measurement shall be carried out to 5 times of
the highest frequency or 6 GHz, whichever is smaller.
5.3 Harmonic Current, Voltage Fluctuations and Flicker
For the electrical self-balancing vehicle with an input current not greater than 16 A, the
harmonic current emission shall comply with the requirements of GB 17625.1.
For the electrical self-balancing vehicle with a rated current not greater than 16 A, the
voltage fluctuation and flicker limits shall comply with the requirements of GB/T
17625.2.
6 Immunity
6.1 Performance Criteria
6.1.1 Overview
During and after the immunity test in accordance with the stipulations of 6.2, the
compliance determination (see Table 5 ~ Table 7) shall be performed in accordance
with the different performance criteria in 6.1.2 ~ 6.1.4, and the details shall be recorded
in the test report.
During the formulation of the test scheme, the manufacturer shall provide necessary
functional descriptions of the electrical self-balancing vehicle published in public prints
and supplement the detailed performance criterion index requirements during and after
the immunity test.
Examples of some of the functions specified by the manufacturer and evaluated during
the test are as follows, but not limited to:
---mobile function;
---meter display;
---power supply;
---communication function.
During and after the immunity test of the electrical self-balancing vehicle, the common
functions and performance degradation phenomena are shown in Appendix A.
6.1.2 Performance criterion A
During and after the test, without operator intervention, the EUT shall be able to
continuously work as expected. When the equipment is used as expected, no
degradation or functional loss below the minimum performance level specified by the
manufacturer is allowed. The allowable performance degradation may be used in place
of the performance level. If the manufacturer does not specify the min...
