What is a battery Electric Vehicle (BEV or EV)?
An electric vehicle (EV) uses an electric motor powered by a battery pack. The battery stores energy as direct current (DC). When you plug the car into the grid, the onboard charger turns the alternating current (AC) from the wall into DC and feeds it into the battery. While driving, an inverter changes the stored DC back into AC so the motor can spin. Regenerative braking reverses the motor to recover energy and recharge the battery, giving quiet, zero-tailpipe-emission travel.
In India, government explainers also group these technologies under the "Faster Adoption and Manufacturing of (Hybrid and) Electric Vehicles"policy umbrella
What are the core advantages and disadvantages of hybrid and electric vehicles?
The advantages and disadvantages of electric vehicles and hybrid vehicles vary due to multiple factors, such as how often you pull over, how much you spend, and how clean your drive feels. Here’s how each system works and what that means for your wheels -
Advantages of a hybrid vehicle
1. Easy transition: No need for dedicated charging infrastructure (except for plug-in variants to maximize benefit).
2. City efficiency: Better fuel economy than conventional ICE, especially in city stop-start traffic, and regenerative braking improves mileage in urban use.
3. Long-trip flexibility: Gradual transition from fuel to partial electrification without range anxiety.
4. Lower emissions than a similar petrol-only car: Traffic-driven emissions fall because hybrids eliminate idling, rely on electric boost for acceleration, and recover energy during deceleration.
Disadvantages of a hybrid vehicle
1. More moving parts: A hybrid combines an internal combustion engine with an electric drive system, so there are more components than in an EV.
2. Limited electric-only driving in most HEVs: Non-plug-in hybrids use small batteries recharged by regenerative braking or the engine; electric-only runs are brief. So, the gasoline engine runs under sustained or heavy driving conditions, meaning fuel is still burned regularly and true zero-emission operation is rare.
3. Taxation: In India, hybrids generally face the standard GST rate for cars with compensation cess, which makes them costlier than EVs taxed at 5 percent.
Advantages of an electric vehicle
1. Low running cost: Electricity costs far less per kilometre than petrol, and without oil changes or complex gearboxes, routine servicing and wear-and-tear expenses plunge.
2. Zero tailpipe emissions: Driving emits no CO₂, NOx, or particulate matter, and continued grid decarbonization further lowers each kilometre’s total climate footprint every year.
3. Incentives and taxes: EVs draw policy support. Central GST on EVs is 5 percent, and India now has updated charging-infrastructure guidelines.
Disadvantages of an electric vehicle
1. Charging time and access: Home installation costs, apartment-parking constraints, and queues at busy fast-charge stations add waiting time versus quick petrol refuelling.
2. Range planning: Road trips require mapping charger availability, considering weather, elevation, battery aging, and scheduling 20-40-minute recharge breaks every few hundred kilometers.
3. Upfront price: Depending on model and features, some EVs can cost more to buy, though incentives, lower GST, and running savings help over time.
