AS/NZS 60335.2.201:2016 pdf free.Household and similar electrical appliances- Safety Part 2.201: Particular requirements for battery powered self-balancing personal transport devices.
18 Endurance
This clause of Part I is not applicable.
19 Abnormal operation
This clause of Part 1 is applicable except as follows.
19.1 Addition:
Battery powered self-balancing personal transport devices are also subject to the test of
19.101 and 19.102.
19.13 Addition:
During the tests the temperature of the battery surface shall not exceed 130°C.
During the tests of 19. 11.2 the battery powered self-balancing personal transport device shall not come to a sudden halt.
19.101 The functional part of the battery powered self-balancing personal transport device with a fully charged battery is subject to an overload condition where the load is increased on the motors until the overload protection or the motor control operates. The motor current that caused the overload protection or motor control to operate is measured. The test is repeated with the functional part of the battery powered self-balancing personal transport device loaded to give a motor current that is 90% of the current that caused the protection or motor control to operate. If the motor control or overload protection again operates, the test is repeated with the motor current reduced in steps of 10% of the current that caused the protection or motor control to first operate until the motor control or overload protection does not operate.
19.102 Battery powered self-balancing personal transport devices with batteries that have cells connected in series are tested as follows.
All cells shall be discharged to the specified fully discharge condition except for one cell which is discharged to approximately 50% of the battery manufacturer’s specified fully discharge condition. The selected cell shall provide the most unfavourable condition of test.
The battery is then charged to the fully charged condition and the voltage across the partially discharged cell is monitored to ensure that the charge voltage does not exceed the maximum voltage limit assigned by the manufacturer.
20 Stability and mechanical hazards
This clause of Part 1 is applicable
21 Mechanical strength
This clause of Part 1 is applicable except as follows.AS/NZS 60335.2.201 pdf download.
