Electric and electrified cars come with an alphabet soup of labels — BEV, HEV, PHEV, “self-charging hybrid.” Underneath the jargon there are really just three ideas. Here’s the plain-English version.
The three types
Full electric (BEV — Battery Electric Vehicle). No engine, no fuel tank, no exhaust. It runs entirely on a large battery that you charge from a socket or charging station. Examples: most cars people mean when they say “an EV.”
Hybrid (HEV — Hybrid Electric Vehicle). A petrol (or diesel) engine paired with a small battery and electric motor. You never plug it in — the battery charges itself from the engine and from braking. The electric motor assists the engine and lets the car creep short distances on electricity, which improves fuel economy but doesn’t give real electric-only range. These are the “self-charging hybrids.”
Plug-in hybrid (PHEV). A halfway house: a bigger battery you do charge from a socket, giving a genuine electric-only range — often around 30–80 km — before a petrol engine takes over for longer trips. Short commutes can be all-electric; long drives work like a normal hybrid.
How they compare
| BEV (full electric) | HEV (hybrid) | PHEV (plug-in hybrid) | |
|---|---|---|---|
| Plug in to charge? | Yes (required) | No | Yes (to get electric range) |
| Petrol engine? | No | Yes | Yes |
| Electric-only range | Whole trip | Barely any | ~30–80 km typical |
| Tailpipe emissions | None | Yes | Only when the engine runs |
| Servicing | Least (no oil/engine) | Engine + battery | Engine + bigger battery |
Which one fits your driving?
- Mostly short local trips, home/work charging available → a BEV is cheapest to run and simplest to maintain.
- Lots of long, unpredictable driving, or no reliable charging → an HEV cuts fuel use with zero charging hassle.
- Short daily commute but occasional long trips → a PHEV can do most days on cheap electricity while keeping petrol range in reserve — if you actually plug it in.
That last point matters: a plug-in hybrid only saves money if you charge it. We break the numbers down in PHEV explained: how plug-in hybrids work and their real running costs.
What they all have in common
Whichever you pick, the ownership basics don’t disappear — they change shape. Every one of these still needs tires, brakes, coolant, registration, and insurance, and every one benefits from tracking its running cost. Electrified cars just shift what you track: charging sessions and battery health instead of (or alongside) oil changes and fuel.
That’s true even in a mixed household — an EV for the commute and a petrol car for road trips is increasingly common, and the multi-vehicle garage keeps each one’s reminders, costs, and history separate. Open the app to add whatever you drive.

Frequently asked questions
What's the difference between a hybrid and a plug-in hybrid?
A regular hybrid (HEV) never plugs in — it charges its small battery from the engine and regenerative braking, and can only travel very short distances on electricity. A plug-in hybrid (PHEV) has a bigger battery you charge from a socket, giving a meaningful electric-only range (often 30–80 km) before the petrol engine takes over.
Is a plug-in hybrid better than a full EV?
It depends on your driving. A PHEV suits people who do short daily trips on electricity but occasionally need long range without charging stops. A full EV (BEV) is simpler, cheaper to run, and zero-tailpipe-emission, but relies on having charging you can access. Neither is universally 'better'.
Do hybrids and EVs need less maintenance?
Full EVs need the least — no oil changes, spark plugs, or exhaust. Hybrids still have a petrol engine to service, but often wear brakes more slowly thanks to regenerative braking. Plug-in hybrids sit in between, with both an engine and a battery to look after.
