Understanding PHEVs
A PHEV has a standard internal combustion engine based drivetrain , either petrol or diesel, that can be used on
its
own or in conjunction with a second electrical motor and battery drivetrain. This allows the benefits of electric
driving where convenient, but also the range and ease of use that traditional internal combustion engines offer, all
in a single package.
How does a PHEV work?
As you can imagine, a PHEV that blends power from two distinct drivetrains needs sophisticated management systems to
get the most from all situations. Driving on electric only, internal combustion (IC) only and even both together,
and it does so using these systems:
Electric Motor — An electric motor that can drive the car on its own forms the core of the
system. This is powered by an onboard rechargeable battery, usually much smaller than a full EV , but enough
to allow full electric only driving for a limited but useful range.
IC Engine — Can be switched on manually or automatically when the electrical system runs low on
power, it provides all the convenience and range that internal combustion vehicles offer.
Braking — System that captures the energy lost due to braking forces, coverts it into
electricity and recharges the battery for future use in the vehicle.
Smart Charging Systems — The most advanced PHEVs make use of smart charging technology to
maximize efficiency and integrate into various EV fleet management systems to allow for
simpler, more effective route and vehicle use management.
The PHEVs with the longest range you can buy today
While the backup of an IC engine means range is never an issue for PHEVs, many have shows to allow for significant
electric only distances, with these being the best.
Chevrolet Volt: A balanced driving experience, with enough electric range for many journeys, and a
reliable IC engine for longer trips.
BMW i3 with Range Extender: Bringing BMWs reputation for luxury and high quality vehicles, it also
offers a long electric only range, and of course, the IC engine if more miles are required.
Toyota Prius Prime: Great for electric only shorter trips, the Prius Prime has a smooth engine and
easy driving when switching to IC power.
Ford Fusion Energi: With a substantial electric only range, the Energi can meet the needs of most
families.
All of these models offer the best of PHEV motoring, allowing you to enjoy the quiet, low cost motoring of electric
only drive, with the range and ease of use of a combustion engine when you need it.
Do You Need to Charge a PHEV?
A PHEV works at its most efficient when the battery is charged regularly so it can use electric power as often as
possible. How often you need to charge will depend on a number of factors, including how the vehicle is used and its
specifications:
Daily Commute Considerations: If you have a relatively short commute, look for a PHEV that can do that range
on electric only. It will considerably lower your travel costs.
Varied Driving Patterns: If you have a mix of short and long journeys, you will be using the internal
combustion engine more frequently, check out the gas mileage to find the most efficient PHEV for you.
Battery Capacity and Usage: A larger capacity battery means a longer electric range, but they also add
weight. If you want to use electric alone for as long as possible, look for models with a bigger battery.
Conclusion
While most people are aware of the benefits of electric vehicles, for many range anxiety is still an issue. PHEVs
combine the best of electric technology with the reliability and ease of use of the familiar gasoline engine, making
them a compelling option for many consumers and a gateway to all electric driving for those who are still unsure.
With so many options now on the market, consumers have a range of vehicle capabilities to suit their specific needs,
helping the industry to transition to the more sustainable
transport solution of the future.
