Phase IFoundation

Background

Overview

Explores sustainable transport solutions, circular economy applications, technological innovation, regulatory challenges in emerging sectors, and potential for green job creation and economic redistribution.

Vehicle retrofitting involves replacing the internal combustion engine (ICE) components of an existing vehicle with an electric powertrain (motor, battery, and controller), thereby converting it into an electric vehicle while retaining the original chassis and body.

Phase IIStatic core

Facts & tables

Key facts

Process

Converts ICE vehicles to EVs by replacing the engine with an electric motor, battery, and controller.

Economic Benefits

Significant cost savings compared to purchasing a new EV (e.g., ₹50k-₹70k for 2W, ₹5L-₹10L for 4W).

Environmental Benefits

Reduces manufacturing emissions of new vehicles, eliminates tailpipe emissions (PM2.5, CO2), and prevents improper disposal of ELVs.

Regulatory Challenges

Lack of formal approval and licensing (e.g., ARAI certification), clear RTO registration frameworks, and OEM involvement.
