TL;DR

Reduce range anxiety for Mahindra EV users by creating a connected IVI and mobile app experience by providing real-time trip feasibility predictions, visualizes range, and recommends reliable charging stations to deliver a seamless, proactive, and trustworthy journey.

Core Experience

I learned how to turn complex contextual data into proactive intelligence that removes uncertainty from EV journeys.


More importantly, I realized that trust is built through transparency by revealing what’s hidden rather than visual polish, and that seamless mobile-to-vehicle continuity is critical to a confident driving experience.

Reducing Range Anxiety for EV Users

Redefining Range Confidence & Trust for EV Users

01 | CONTEXT

India is the world's third-largest automotive market, shifting fast to electric. Mahindra leads with the BE 6e and XEV 9e.

But the infrastructure hasn't caught up with the ambition and the gap lives entirely in the driver's head.

India's EV moment, held back by one feeling.

City-based EV owners, 30–45 yrs. Drive 40–80km daily. High digital literacy. Fear long trips.

~800K

Weekend + holiday drivers, 150–400km trips. Cross-references 3+ apps before leaving. Most anxious.

~320K

Just switched from ICE. Doesn't understand battery behavior. Needs education + reassurance. Highest churn risk.

~480K

URBAN DAILY COMMUTER

INTERCITY TRAVELLER

FIRST TIME EV ADOPTER

WHO ARE WE DESIGNING FOR?

70%

of EV owners experience anxiety about running out of charge

65%

use guesswork to plan charging & no predictive tools exist

30%

real-world range variance from static estimates & ignored by current IVI

60%+

of potential buyers cite range uncertainty as reason to delay EV purchase

THE PROBLEM

02 | HYPOTHESIS

Before any research, we formed core hypotheses - testable beliefs about user behavior and system design that would guide every decision.

What we were betting on.

"If the system explains why range drops, users will trust it more than if it just shows accurate data."

HYPOTHESIS 01 · TRUST

"If we show trip feasibility before departure, users will attempt longer journeys they currently avoid."

HYPOTHESIS 02 · ACTIVATION

SERVICE CARE

Stay in sync with your car's service journey - from booking slots to real-time tracking and personalized care

ONBOARDING

A quick setup understands how you drive and where you go, so every prediction, charge stop, and alert feels tailored, not generic.

A centralized control hub for secure payments and real-time service insights to emergency support and digital documents.

Personal Details, Charging History, Payment and Emergency - All in one?

Takes time to open up the app and search?


Find the charging station as soon as you open the app based on your location.


Add it as a widget to you Home Screen to save time searching

Real-time discovery. Effortless navigation. Zero range anxiety.

CHARGING STATION

Charging, Simplified

Intelligently plans your EV journeys predicting energy usage, recommending optimal charging stops, and recalculating routes in real time so you always stay in control.

TRIP PLANNER

Drive farther with confidence

An intelligent HMI that predicts range, plans charging, and adapts routes in real time.

Confidence, built into every EV journey

Charging stations integrated into the journey to enable seamless long-distance EV travel.

Get live charging updates in the In-Vehicle Dashboard without opening your phones

Predictive battery insights that help drivers understand range and make confident charging decisions.

Maps and insights making your journey smooth

A navigation system that dynamically optimizes routes based on energy consumption, traffic, and distance.


Adaptive EV Navigation

The most powerful UX decisions happen in the background, where trust is built through honesty and problems are rarely where you expect them, and even initial domain ignorance can become a design advantage, followed by usability testing to validate assumptions and iterating based on real user feedback.

10 | KEY LEARNINGS

What this project actually taught me.

Not just design skills, ways of thinking I didn't have before. Each one is a tool I'll carry into every project from here.

09 | KNOWLEDGE GAP

What we didn't know going in.

The gaps we identified before research started and how we closed them. Being honest about what you don't know is how you design the right research.

08 | BUSINESS IMPACT

Designed for scale from day one.

Projected increase in long distance trip attempts when drivers have pre departure confidence scoring expands EV use beyond city commuting.

REVENUE LAYER

RETENTION DRIVER

Daily active usage vs. stock IVI system

3× DAU

04 | THE STRATEGY SHIFT

Before designing screens, we mapped the entire EV journey to locate where trust bleeds out. The problem wasn't the battery. It was the silence around it.

From reactive to anticipatory.

05 | AARRR - FULL GROWTH FRAMEWORK

We didn't design features and then find where they fit in AARRR. We built the product so that every touchpoint directly addresses a specific growth lever - acquisition, activation, retention, revenue, or referral.




Every feature is a growth mechanism.


BEFORE - REACTIVE SYSTEM


✖ Static battery % with no context


✖ Range drops without explanation


✖ Manual charger search across 3+ apps


✖ No trip feasibility before departure


✖ Driver carries all cognitive load


✖ No learning from past trips

AFTER- ANTICIPATORY SYSTEM


✔ Context-aware range with terrain, traffic, AC


✔ Proactive “why” alerts on any deviation


✔ Unified charger reliability layer in-app


✔ Pre-departure feasibility score


✔ System carries the mental math


✔ Post-trip data improves future predictions

60–70% of buyers delayed by range fear (content, word-of-mouth, brand trust reduce this)

First meaningful moment: feasibility score shown for user’s real route in <3 min

Daily pre-trip ritual. Post-trip insights. Battery health loop. 3× DAU vs. stock IVI

01 DOMAIN KNOWLEDGE

Range is not fixed. It shifts with speed, terrain, and temperature. We needed to understand the system before designing for the user.

02 INFRASTRUCTURE REALITY

The charging network is inconsistent. Reported reliability did not match reality. Broken stations, incompatible systems, and app dependency were common.

03 MENTAL MODELS

Users think in fuel, not range. Most drivers still approach EVs like petrol vehicles, which creates anxiety and poor planning.

04 IVI DESIGN CONSTRAINTS

Designing for attention, not interaction. Every second matters in a moving car. Information needs to be instant, clear, and glanceable.

IN-VEHICLE INFOTAINMENT SYSTEM

Glad we could cross paths!

I hope it left you with a bit of curiosity and inspiration.
