The most helpful first distinction is where energy enters the vehicle: from a charging cable, from fuel, or from both.
Three useful categories
The Department of Energy identifies all-electric vehicles, plug-in hybrids and conventional hybrids. Battery-electric vehicles draw propulsion energy from electricity. Plug-in hybrids use electricity and fuel. Conventional hybrids combine an engine and electric drive without external plug-in charging.
Turn labels into a reading framework
Imagine two information cards. The first states that a vehicle can be charged externally; the second uses the word “hybrid” but gives no charging information. Do not assume the cards describe equivalent systems. Look for the actual powertrain classification and the local model specification.
A more detailed technical description may explain how the engine and motor contribute under particular conditions. Keep that description attached to the exact system. A marketing term applied across several products may hide differences that matter to a technical comparison.
Ask the same questions of both vehicles
For a comparison, use a common set of questions: what energy sources can be supplied, which distance figures are published, what operating conditions are stated, and what equipment belongs to the local version? Retain the original units and test descriptions.
For an illustrative case, a reported battery-only distance and a reported distance with both battery and fuel available should occupy separate rows. The table should reveal the difference rather than conceal it inside a single “range” column. This approach explains the technologies without assuming their suitability for every household.
