With smaller batteries than battery-electrics, plug-in hybrids achieve an electric-only range of 20‒55 miles, during which they produce no tailpipe emissions. When the vehicle uses up its electric range, it switches to gas and drives just like a conventional car.
From listening to the radio to powering the wheels, plug-in hybrids harness energy from both the combustion engine and electricity. The range will generally be around 20-30 miles, but some of the latest PHEVs have an official pure electric range of more than 50 miles depending on your driving style.
Plug-In Hybrids: More Range, More Cost
This ability to charge batteries in advance enables a plug-in hybrid to drive on pure electric power without burning any fuel. Some plug-ins can go 25 miles or more (see the list below).
Whenever you decelerate or use the brakes, the regenerative braking system harvests electricity and stores it in the battery for use later on, but the car can run solely on electricity for only up to 1.25 miles.
Unlike pure EVs or conventional hybrids, plug-in hybrid-electric vehicles have electric ranges that are usually between 20 and 40 miles per charge and then revert to regular hybrid operation.
Plug-in hybrids may drive for 10-50 miles using only electricity before they start using gasoline, and can then drive for about 300 miles (depending on the size of the fuel tank, just like any other car).
The main downside of owning a PHEV is that it's likely to have poorer fuel economy than a conventionally-powered alternative when it's driven using the engine rather than the electric motor. This is because you're lugging around the additional weight of its electric battery pack.
The car starts up in electric mode automatically and stays in this mode up until a speed between 43 mph and 80 mph. If additional power is needed, or if the battery's charge is too low, then the car will activate the combustion engine.
Mild hybrid cars are very similar to self-charging hybrids but have a much smaller battery. This means the vehicle can't drive on battery power alone, and the battery helps the petrol or diesel engine perform more economically.
Mild hybrids use regenerative braking to charge the battery while driving. They don't charge from an external power source and are not capable of electric-only driving.
Only Answer
No. Though a hybrid vehicle can operate in electric-only mode when gasoline is in the tank, it is not designed to run without gasoline. Doing so could cause severe damage to the hybrid system, so drivers should be sure to keep gas in the tank at all times.
The vehicle typically runs on electric power until the battery is nearly depleted, and then the car automatically switches over to use the ICE. Learn more about plug-in hybrid electric vehicles.
A plug-in hybrid may be able to get a little charge through regenerative braking. But since a plug-in car has a larger battery that it relies on more, it needs to be connected to an external power source to fully recharge. Full hybrids can recharge their electric batteries through regenerative braking.
Are plug-in or self-charging hybrids better? On paper, plug-in hybrids are more efficient than a self-charging hybrid, the bigger battery means a PHEV can cover more miles in 100% electric mode. However, this isn't a disadvantage if you're primarily using the car for city driving.
Electric cars do not need fuel to run. That fact alone can tell us that EVs are much cheaper to run than hybrid and combustion engine cars, which both need fuel. Electric cars do need to get plugged in regularly to have power stored in their batteries.
What's the difference between PHEV and MHEV? A plug-in hybrid vehicle (PHEV) has a smaller fuel engine and can be powered exclusively by a large battery pack. A mild hybrid electric vehicle (MHEV) blends a traditional fuel engine and electric power.
Ease of use
So even if you don't have off-street parking or charging points at work, they're still a viable option. While not as efficient as plug-in models on paper, if used primarily around town and at lower speeds, these regular hybrids can be impressively efficient.
The main difference is that while a normal hybrid car can run on electric power alone, a mild hybrid cannot. The mild hybrid system just works alongside the petrol engine to provide a boost of performance and economy.
You should also try to drive at lower speeds and cruise at around 60 mph instead of 70 mph if the speed limit is 55 mph. These simple acts can do wonders to reduce your gas consumption.
Standard Hybrids: Standard hybrids use an electric motor and an internal combustion engine. They are also the first type of hybrid vehicle on the market. Thus, charging a hybrid car battery requires no change from your routine. The hybrid battery self charges while you drive, and you can use gasoline as a power source.
At lower speeds, a hybrid vehicle typically runs on its electric battery. The hybrid's internal computer system tells the vehicle to switch to gas when you accelerate.
Battery degradation is one of the most common problems with hybrid cars. This can cause a decrease in the car's performance and mileage, as well as an increase in fuel consumption. The battery may eventually lose its capacity over time, leading to decreased performance and range from the vehicle.
If you have a very long commute or no way to quickly and easily charge up, stick with a traditional hybrid. If you want an all-electric car but take frequent road trips and are concerned about your ability to charge up your vehicle on the road, a plug-in hybrid is probably best for you.
PHEVs are slowly becoming less relevant, as owners are almost exclusively using the gasoline engine and not touching the electrical power. Plug-in hybrids are rapidly becoming one of the most popular forms of vehicle on the planet, as we move away from pure internal combustion power.
