This paper presents a modeling approach based on numerical reduced-order modeling (ROM) to analyze the thermal behavior of electric traction motors.

This Indian Standard (Part 21/Sec 1) which is identical with IEC 61851-21-1: 2017 ‘Electric vehicle conductive charging system — Part 21-1: Electric vehicle on-board charger EMC requirements for conductive connection to an AC/DC supply’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Electrotechnology in Mobility Sectional Committee and approval of the Electrotechnical Division Council.

The automotive industry in India, with respect to EV implementation is facing issues including economic downturn to the need to improve emissions performance and urgency to shift to electrification.

This Indian Standard (Part 4) which is identical with ISO 15118-4: 2018 ‘Road vehicles — Vehicle to grid communication interface — Part 4: Network and application protocol conformance test’ issued by the International Organization for Standardization(ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Electrotechnology in Mobility Sectional Committee and approval of the Electrotechnical Division Council.

This standard (Part 1) specifies the method for measurement of electrical energy consumption expressed, in Wh/ km for L, M and N categories of electric power train vehicles.

This standard (Part 2) specifies the method for measurement of a range expressed, in km for L, M and N categories of electric power train vehicles.

This standard (Part 3) applies to the representation of the curve as a function of motor speed and the power at full load indicated by the vehicle/motor manufacturer for motors of electric drive trains and the maximum 30 min power of electric drive trains intended for the propulsion for L, M and N categories of electric power train vehicles.

Based on ownership and user preferences, light duty and local delivery medium-duty EVs are typically connected to grid distribution networks whereas larger medium duty and heavy-duty EVs are typically connected to distribution or even sub-transmission networks.

This Indian Standard (Part 21/Sec 2) which is identical with IEC 61851-21-2: 2018 ‘Electric vehicle conductive charging system — Part 21-2: Electric vehicle requirements for conductive connection to an AC/DC supply- EMC requirements for off-board electric vehicle charging systems’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Electrotechnology in Mobility Sectional Committee and approval of the Electrotechnical Division Council.
