ISO/TS 4210-10:2020 サイクル—自転車の安全要件—パート10：電動アシストサイクル（EPAC）の安全要件 | ページ 6

3.1

cycle

any vehicle which has at least two wheels and is propelled by the muscular energy of the person on that vehicle, in particular by means of pedalling or the possibility of adding assistance provided by electric motor when pedalling

Note 1 to entry: Pedalling also refers to use of hand cranks or other similar devices.

3.2

electrically power assisted cycle

EPAC

cycle (3.1) , equipped with pedals and an auxiliary electric motor, which cannot be propelled exclusively by means of this auxiliary electric motor, except in the walk assistance mode

3.3

mountain EPAC

electrically power assisted cycle (3.2) designed for use off-road on rough terrain, on public roads, and on public pathways, equipped with a suitably strengthened frame and other components, and, typically, with wide-section tyres with coarse tread patterns and a wide range of transmission gears

[SOURCE:ISO 4210‑1:2014, 2.30, modified — bicycle has been changed to electrically power assisted cycle.]

3.4

braking device cut-off switch

device that cuts off the motor assistance while braking

3.5

continuous rated power

output power specified by manufacturer, at which the motor reaches its thermal equilibrium at given ambient conditions

3.6

assisted rate

ratio of between mechanical motor output-power and muscular human input-power

3.7

thermal equilibrium

temperatures of motor parts which do not vary more than 2 °C/h

3.8

assistance cut-off speed

speed at which the motor controller cuts off the assistance of the auxiliary electric motor

3.9

walk assistance mode

function by which the user can activate the auxiliary electric motor to propel the EPAC up to a defined maximum speed without pedalling

3.10

electromagnetic compatibility

ability of an EPAC or one of its electrical/electronic systems to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbance to anything in that environment

[SOURCE:IEC 60050‑161:1990/AMD8:2018, IEV ref. 161‑01‑07, modified — an EPAC or one of its electrical/electronic systems have been specified.]

3.11

ESA

electronic subassembly

electrical subassembly

electronic and/or electrical component, or an assembly of components provided for installation into an EPAC, together with all electrical connections and associated wiring for the execution of several specific functions

3.12

motor controller

device or group of devices that serves to govern in some predetermined manner the performance of an electric motor

Note 1 to entry: Means for manual or automatic ON/OFF, selecting the drive direction, regulating the speed, limiting the torque and providing protection against faults.

3.13

fault condition

condition in which one or more fault is present which could cause hazard

3.14

charging configuration

sets of physical parameters which are predefined to control a charging process

3.15

battery management system

BMS

local energy management system for the battery system, protecting the battery system from damage, monitoring and increasing the lifetime, and maintaining the functional state

Note 1 to entry: BMS and BCU (according to ISO 12405) do not have the same functions.

3.16

narrow-band emission

emission which has a bandwidth less than that of a specific receiver or measuring instrument

3.17

no load current point

current measured at battery output with no change to the operating status of any auxiliary systems during the test

3.18

safety extra-low voltage

SELV

voltage not exceeding ripple-free 60 V d.c. between conductors and earth, the no load voltage not exceeding ripple-free 60 V d.c.

3.19

anti-tampering measures

technical requirements and specifications which prevent, as far as possible, unauthorized modifications of the EPAC's drive system which may prejudice functional safety

3.20

maximum permissible load

maximum permissible weight of rider and luggage as defined by the manufacturer

3.21

proprietary system

manufacturer-specific system

3.22

non-proprietary system

non manufacturer-specific system

3.23

charger inlet

inlet on the EPAC or battery side for charging

[SOURCE:IEC 60050‑714:1990, IEV ref. 714‑03‑04, this source is only for “inlet”]

3.24

charger connector

connector on charger side for charging

[SOURCE:IEC 60050‑151:2001, IEV ref. 151‑12‑19, this source is only for “connector”]

3.25

rigid seat-post

seat-post that cannot be raised or lowered independently of the seat tube clamp, while riding, and does not provide controlled axial flexibility to reduce the transmission of road shocks to the rider.

3.26

suspension seat-post

seat-post incorporating controlled, axial flexibility to reduce the transmission of road shocks to the rider

3.27

dropper seat-post

seat-post that can be raised or lowered independently of the seat tube clamp while riding

3.28

suspension dropper seat-post

seat-post incorporating controlled, axial flexibility to reduce the transmission of road shocks to the rider and incorporating the capability of raising and lowering independently of the seat tube clamp while riding
