Summary:

In India, Currently Continuous FULL MIDC (Modified Indian Driving Cycle) is used to declare the Range and Energy consumption of BEV (Battery Electric Vehicle). AISC (Automotive Industry Standards Committee) is looking to implement Worldwide Harmonized Light-Duty Test Procedure (WLTP) in India. AISC released AIS 175 for WLTP implementation from Apr 2027. The objective of WLTP is to standardize the test procedure globally for evaluating Emission/FE/Range of Light Duty Vehicles. But the effect of AIS 175 regulation on Battery Electric Vehicles Range Declaration is very less. The Range is almost same as Full MIDC declared Range.The On-road Range BEV is always lesser than the Declared Range of vehicles because of ambient conditions. Usually, the Full MIDC declared Range will be 20% ~26% higher than actual On Road Range. The Range of BEV as per India WLTP 3-Phase was observed 18% ~ 24% higher than actual On-road range of vehicles. There is only 2% difference observed between Full MIDC Range test and India WLTP 3-Phase PER test results. The Energy Consumption of WLTP 3-Phase test is 7% better than MIDC Energy Consumption test (AIS 039).To develop and declare the range of BEV's near to on-road range better WLTP test cycle is required. So, we created New India WLTP 4-Phase test cycle with 4Phases: Low, Medium, High1, High2 (reference from Europe WLTP, instead of Extra-High phase, High phase repeated, just like NEDC to MIDC).The Range observed in India WLTP 4-Phase is only 10% ~ 16% higher than on-road Range of vehicle. The difference between India WLTP 3-Phase vs India WLTP 4-Phase for Range and Energy consumption was 6%Implementing India WLTP 4-Phase test cycle will provide very realistic range estimation results for Indian driving conditions compare to India WLTP 3-Phase test cycle
