The batteries take a shorter time to be charged to a full capacity. This is because of the smaller sizes, which are less efficient than a plug-in battery. When fully charged, fully hybrids cover less than a mile on electric-only drive mode, which automatically switches to fuel mode when the battery runs low.
How long can a plug in hybrid battery last?
Plug-in hybrids (PHEV) are charged by an external power source. You can charge it overnight or at your various destinations when going on a long journey. A fully charged battery can cover up to 300 miles since the larger and broader batteries provided can last for long. Owners who rarely cover their car’s electric-only limit of 30 miles a day can theoretically drive on electric motors without using the fuel engine for long.
Why is it called self charging?
The reason for calling them self-charging is because you don’t need to plug into the mains, instead the battery tops up while driving. The self-charging batteries recover energy lost while the car is moving, or during braking. Just like the dynamo powering up the light on an old bicycle, the petrol or diesel engine powers up the battery whenever it runs low.
Why is PHEV fuel consumption higher?
This results in higher fuel consumption due to the added weight of the plug-in hybrid systems.
