How Does an Electric Vehicle Work?
An electric vehicle (EV) replaces the internal combustion engine with an electric motor powered by a battery pack. When you press the accelerator, electricity flows from the battery to the motor, which turns the wheels. No fuel, no exhaust, no gearbox.
Battery Pack
Stores electricity. Capacity measured in kWh (kilowatt-hours). Bigger battery = more range, more weight, higher cost.
Electric Motor
Converts electricity to motion. Instant torque — full acceleration from 0 rpm. No gears needed.
Onboard Charger
Converts AC power from the grid to DC for the battery. Limits your maximum AC charging speed.
BMS
Battery Management System — the brain that controls charging, temperature, and protects battery health.
Types of Electric Vehicles
| Type | How It Works | Best For |
|---|---|---|
| BEV (Battery Electric) | 100% electric, no petrol engine. Charged from grid. | Most people — lowest running cost |
| PHEV (Plug-in Hybrid) | Electric motor + petrol engine. Can run on both. | Those with range anxiety or frequent long trips |
| HEV (Hybrid) | Petrol engine + small battery. Cannot plug in. | Those not ready for full EV yet |
| FCEV (Fuel Cell) | Hydrogen fuel cell generates electricity. | Heavy transport, long-haul trucks (early stage) |
EV vs Petrol — Key Differences
Running Cost
EVs cost 60–75% less per km than petrol. Electricity is cheaper than fuel, and EVs need less maintenance (no oil changes, fewer brake replacements due to regenerative braking).
Maintenance
EVs have ~20 moving parts vs ~2000 in a petrol car. No oil, no timing belt, no spark plugs. Main service items: tyres, brake fluid, cabin air filter, battery health check.
Performance
Electric motors deliver instant torque. Even budget EVs feel quick off the line. No gear changes = smooth, linear acceleration.
Environment
Zero tailpipe emissions. Even accounting for electricity generation, EVs produce 50–70% less lifetime CO2 than equivalent petrol cars.
Charging at Home — The Game Changer
The biggest lifestyle difference with an EV: you "refuel" at home. Plug in every night, wake up with a full battery. No more petrol station visits for daily driving.
- Standard wall socket — Works but slow (adds ~25 km/hour). Fine if you drive <50 km/day.
- Dedicated home charger (wallbox) — 7–22 kW. Adds 50–130 km/hour. Recommended for most EV owners. Installation cost: ₹15,000–40,000 including hardware and electrician.
Public Charging — When You Need It
For trips beyond your home range, use public charging stations. Use ChargeRoute to find stations along your exact route before you leave. Most EV owners use public fast chargers only on road trips — not for daily driving.

| Cost | Petrol Car | Electric Car |
|---|---|---|
| Fuel/Electricity per 100 km | ₹350–600 (petrol) | ₹80–150 (electricity) |
| Annual servicing | ₹8,000–25,000 | ₹3,000–8,000 |
| Brake pad replacement | Every 2–3 years | Every 5–7 years (regen braking) |
| Engine oil changes | Every 6 months | Never (no engine oil) |
Tips for First-Time EV Buyers
- Range: buy more than you think you need — Get at least 50% more range than your average daily driving. You'll use it on unexpected long days.
- Check home charging compatibility — Before buying, confirm your parking spot has an electrical outlet or can have one installed.
- Test drive before buying — The instant torque and regenerative braking feel very different from petrol. Most people love it — but try first.
- Check government incentives — Many countries offer EV subsidies, reduced road tax, and free parking. India has FAME II scheme benefits for eligible models.
- Consider total cost of ownership — EVs cost more upfront but significantly less to run. Calculate 5-year total cost, not just purchase price.
Frequently Asked Questions
How long do EV batteries last?
Modern EV batteries are designed to last 150,000–300,000 km or 8–15 years. Most manufacturers offer 8-year battery warranties. Battery degradation is typically 10–20% over 10 years, meaning your range reduces gradually — not suddenly.
Can I charge my EV in the rain?
Yes — EV charging systems are fully waterproof and designed for outdoor use in all weather. Both the car's charging port and public charging stations meet strict IP (ingress protection) ratings for water resistance.
Is it safe to buy an EV right now or should I wait?
2025 is a great time to buy an EV — ranges are practical, charging infrastructure is expanding rapidly, and purchase prices have fallen significantly. Waiting for "perfect" technology means missing years of fuel savings. The best time to switch is now.
