Consider the following types of vehicles:
I. Full battery electric vehicles
II. Hydrogen fuel cell vehicles
III. Fuel cell electric hybrid vehicles
How many of the above are considered as alternative (powertrain) vehicles?
Detailed Explanation:
Alternative powertrain vehicles are vehicles that do not rely on conventional petrol or diesel internal combustion engines as their primary source of propulsion.
-
Statement I is Correct: Battery Electric Vehicles (BEVs) run entirely on electricity stored in batteries.
-
Statement II is Correct: Hydrogen Fuel Cell Vehicles (FCEVs) generate electricity from hydrogen using fuel cells.
-
Statement III is Correct: Fuel Cell Electric Hybrid Vehicles (FCEHVs) combine fuel cells, batteries, and electric motors.
-
Therefore, all three are considered alternative powertrain vehicles, making Option C the correct answer.
Vehicle-wise Analysis
| Vehicle Type | Alternative Powertrain? | Explanation |
|---|---|---|
| Full Battery Electric Vehicle (BEV) | ✅ Yes | Powered solely by batteries and electric motors. |
| Hydrogen Fuel Cell Vehicle (FCEV) | ✅ Yes | Uses hydrogen fuel cells to generate electricity. |
| Fuel Cell Electric Hybrid Vehicle (FCEHV) | ✅ Yes | Combines hydrogen fuel cells with battery storage. |
Alternative Powertrain Vehicles
What are Alternative Powertrains?
These are vehicle propulsion systems that use alternatives to conventional petrol or diesel engines.
Major Types
| Type | Energy Source |
|---|---|
| BEV | Battery Electricity |
| FCEV | Hydrogen Fuel Cell |
| FCEHV | Hydrogen Fuel Cell + Battery |
| HEV | Fuel + Electric Motor |
| PHEV | Plug-in Battery + Fuel Engine |
Important Facts
-
BEVs produce zero tailpipe emissions.
-
FCEVs emit only water vapor as a by-product.
-
Hydrogen-based vehicles are considered important for long-range and heavy-duty transport.
-
Alternative powertrains help reduce dependence on fossil fuels and lower carbon emissions.
