ISO/TC 22/SC 38/WG 2 - Electric mopeds and motorcycles

This document specifies safety requirements for conductive connection of electrically propelled mopeds and motorcycles (referred to as the EVs) to external electric circuits. NOTE 1 External electric circuits include external electric power supplies and external electric loads. It does not provide comprehensive safety information for manufacturing, maintenance and repair personnel. It applies only to on-board charging systems between the plug or vehicle inlet and RESS circuits. NOTE 2 The requirements when not connected to external electric circuits are specified in the ISO 13063 series. Requirements for bidirectional energy transfer DC to AC are under consideration and are not part of this document. NOTE 3 The safety requirements for DC EV supply equipment where protection relies on electrical separation are specified in IEC 61851-25. NOTE 4 The safety requirements for DC EV supply equipment where protection relies on double or reinforced insulation are specified in IEC TS 61851-3-1 and IEC TS 61851-3-2.

This document specifies safety requirements for rechargeable energy storage systems (RESS) of electrically propelled mopeds and motorcycles for the protection of persons. It does not provide the comprehensive safety information for the manufacturing, maintenance and repair personnel. NOTE Additional safety requirements can apply for RESS that can be recharged by means different from supplying electric energy (e.g. redox flow battery).

This document specifies requirements for operational safety means and protection against failures related to hazards specific to any kind of electrically propelled mopeds and motorcycles when used in normal conditions. It is applicable only if the maximum working voltage of the on-board electrical circuit does not exceed 1 000 V alternating current (a.c.) or 1 500 V direct current (d.c.). This document does not provide comprehensive safety information for manufacturing, maintenance and repair personnel. This document does not consider specific aspects of driving automation features. NOTE For definition of the term “driving automation features”, see SAE J3016.

This document specifies electric safety requirements for protection against electric shock and thermal incidents of electric propulsion systems and conductively connected auxiliary electric systems of-electrically propelled mopeds and motorcycles when used in normal conditions. It is applicable to a maximum working voltage of the on-board electrical circuit up to 1 000 V alternating current (a.c.) or 1 500 V direct current (d.c.). This document does not provide comprehensive safety information for manufacturing, maintenance and repair personnel. NOTE Requirements for conductive connections of electrically propelled mopeds and motorcycles to an external electric power supply are described in ISO 18246.

This document specifies a test method to evaluate energy performance of electric motorcycles and mopeds by measuring performance of a test motor system (3.4) to be installed to an electric moped or motorcycle under consideration. The test is carried out on a motor dynamometer test bench where the traction motor system is connected to a load motor system (3.3) that simulates resistance torque arising from running resistance of vehicle and drive train friction loss and inertia effect. This method provides estimates of specific energy consumption and range of an electric moped or motorcycle to which the traction motor system is intended to be applied. This document is only applicable to two-wheeled motorcycles and mopeds. NOTE This test method is applicable to motorcycle or moped regardless of types of power transmission devices, such as chains, belts, gears, ratio controllable CVTs, shaft drives, direct drives, etc., once gear ratios (ratio of input to output speed) and transmission efficiencies (ratio of input to output torque) are provided.

ISO 18246:2015 specifies safety requirements for conductive connection to an external electric power supply of electrically propelled mopeds and motorcycles. It is not applicable to vehicles not in normal conditions, such as damaged vehicles and vehicles which have mechanical and/or electrical failure. It applies only to on-board charging systems between the plug or vehicle couplers and RESS circuits. The safety requirements for vehicles not connected to external power supply are specified in ISO 13063. NOTE This International Standard does not contain requirements for bidirectional power flow. It does not provide comprehensive safety information for manufacturing, maintenance and repair personnel.
