Safety of household and similar electrical appliances—Part 125：Particular requirements for self-balancing personal transport devices for use with batteries containing alkaline or other non-acid electrolytes
GB/T 4706.125-2024 Safety of household and similar electrical appliances - Part 125: Particular requirements for self-balancing personal transport devices for use with batteries containing alkaline or other non-acid electrolytes
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This document deals with the electrical safety of self-balancing personal transport devices for use with batteries containing alkaline or other non-acid electrolytes.
Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account
——persons (including children) whose
• physical, sensory or mental capabilities; or
• lack of experience and knowledge
prevents them from using the appliance safely without supervision or instruction;
——children playing with the appliance;
——operational safety such as speed restriction, falling hazards, rapid acceleration.
Note 101: Attention is drawn to the fact that
——for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;
——in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national transport authorities and similar authorities.
Note 102: This standard does not apply to
——appliances intended exclusively for industrial purposes;
——appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);

3 Terms and definitions
This clause of GB/T 4706.1-2024 is applicable except as follows.
Addition:
For the purposes of this standard, the terms and definitions given in IEC 62133-2 also apply.
3.1 Definitions relating to physical characteristics
Replacement:
3.1.9
normal operation
operation of the appliance under the conditions specified in 3.1.9.101 to 3.1.9.103
3.1.9.101
the functional part of the SPTD, with a fully charged battery is operated in such a way to simulate the riding position and is operated on a continuous belt or rollers. The appliance is loaded with a mass of 100 kg or the maximum load specified in the instructions, whichever is higher. The motors are loaded to 66 % of their locked rotor current by adjusting the load on its rotational axis in the forward direction.
3.1.9.102
the functional part of the SPTD incorporating a discharged battery that is recharged in the appliance is connected to its detachable power supply part and the discharged battery is fully recharged
3.1.9.103
discharged batteries that are not recharged in the appliance are connected to a battery charger and fully recharged
3.1.101
cycle
tc
time required for the fully charged battery to be discharged (td) while under the conditions of normal operation until the appliance no longer operates plus the time required for the battery to be fully recharged (tr) from this discharged condition
Note: tc = td + tr
3.5 Definitions relating to types of appliances
3.5.101
self-balancing personal transport device; SPTD
appliance comprising a detachable power supply part and a functional part
Note 1: The functional part has one or more wheels controlled by the self-adaption of the body of the user and is powered by rechargeable batteries with one or more motors to drive one or more wheels.
Note 2: The functional part may incorporate the battery charging circuitry and other supply unit circuitry. (See Annex B item b)).
Note 3: The term battery as used throughout this document means “secondary battery” as defined in IEC 62133-1 and 62133-2.
3.6 Definitions relating to parts of an appliance
3.6.2
Addition:
Note 101: If a part has to be removed with a tool solely to discard the battery before scrapping the appliance, this part is not considered to be a detachable part even if the instructions state that it is to be removed.
