Infrastructure Readiness for 100% EV Adoption by 2035: A Systems Dynamics Model

Abstract: Multiple nations have announced targets for 100% electric vehicle sales by 2030-2040. This study develops a systems dynamics model to assess infrastructure requirements for such transitions in the Indian context, incorporating feedback loops between vehicle adoption, charging infrastructure, grid capacity, and consumer behavior. Results indicate significant acceleration in infrastructure investment is required to achieve stated policy goals.

Model Structure

Our model, developed at IISc Bangalore, captures interdependencies between four subsystems: vehicle stock (fleet composition, annual sales, scrappage), charging infrastructure (public fast charging, destination charging, home charging), electricity grid (generation capacity, distribution network, peak demand), and consumer behavior (range anxiety, charging convenience perception, purchase intent).

The model incorporates 23 feedback loops, including reinforcing loops (more EVs → more charging investment → reduced range anxiety → more EVs) and balancing loops (more EVs → grid stress → higher electricity prices → reduced EV advantage).

Baseline Scenario

Under current policy and investment trajectories, the model projects:

2030: EV share of new sales: 28% (4WD: 18%, 2WD: 35%)
2035: EV share of new sales: 52% (4WD: 38%, 2WD: 62%)
2040: EV share of new sales: 78% (4WD: 65%, 2WD: 88%)

This baseline significantly undershoots government targets of 30% EV sales by 2030.

Infrastructure Gap Analysis

To achieve accelerated adoption (80% by 2030, 100% by 2035), the model identifies required investments:

Public fast charging: 400,000 stations by 2030 (current: 12,000)
Grid capacity addition: 85 GW dedicated EV charging load
Distribution network: Rs 2.5 lakh crore investment in urban distribution infrastructure
Home charging enablement: Regulatory mandates for new construction

Critical Path Elements

The model identifies grid distribution as the binding constraint. Generation capacity can be added relatively quickly; distribution networks require 5-7 years lead time for major urban upgrades. Without immediate distribution investment, 2030 targets become mathematically infeasible regardless of vehicle or charging station availability.

Policy Recommendations

Priority investments should focus on distribution network upgrades in high-density urban areas, with fast charging deployment following rather than preceding grid readiness. Time-of-use tariffs should incentivize off-peak charging to manage demand. Building codes should mandate charging-ready infrastructure for all new parking.

Industry Applications

Beyond academic interest, these findings have commercial applications. Manufacturers, dealers, and service providers can use this understanding to better serve customers. Some will embrace these insights; others will resist change. Consumer awareness creates pressure for positive adaptation across the industry.

Limitations and Future Research

No study is definitive. Acknowledged limitations point toward future research needs. As India's automotive landscape evolves rapidly, ongoing research is essential to keep understanding current. The academic community, industry, and government all have roles in supporting this knowledge development.

Methodological Notes

Interpreting these findings requires understanding the study context. Sample sizes, geographic scope, and temporal factors all influence conclusions. Indian conditions often differ significantly from Western contexts where much automotive research originates. Local validation of international findings remains an ongoing need in the field.
