How PHEVs Move: The Three Musketeers of Propulsion

PHEVs have three main hybrid system setups: series, parallel, and series-parallel. Imagine them as different ways of combining the power of the gasoline engine and the electric motor.

  • Series PHEVs:Here, the engine acts as a generator, feeding power to the electric motor that drives the wheels. The battery acts like a middleman, balancing the flow of electricity.
  • Parallel PHEVs:This system boasts two independent powertrains – a traditional gasoline engine and an electric motor. They can work together or take turns propelling the car, offering a simpler design and lower initial cost.
  • Series-Parallel PHEVs:This is the most adaptable option. It combines the series and parallel setups, allowing for both independent and combined operation of the engine and motor. This offers more control over how the engine and electric motor work together.

Finding the Perfect Balance: Battery Size vs. Efficiency

Studies show that most daily commutes fall under 50-60 kilometers. So, ideally, a PHEV’s battery should be big enough to cover these short trips electrically. However, a larger battery (think over 150kg) using Lithium-ion technology can significantly impact the car’s overall efficiency. This has been a challenge for PHEVs, similar to fully electric vehicles and even some hybrids.

The Rise of REVs: The Best of Both Worlds?

A new contender has entered the ring – the REV (Range Extender Electric Vehicle). It operates similarly to a PHEV in series mode, but with a twist. REVs come equipped with a small gasoline engine that acts as a generator to recharge the battery when it runs low. Think of it as a backup power source for longer trips, ensuring you don’t get stranded with a depleted battery.

Important Note: The Engine Doesn’t Drive, It Charges

It’s crucial to remember that the REV’s engine doesn’t directly power the wheels. Its sole purpose is to recharge the battery, extending the car’s electric range. The Chevrolet Volt with its 1.4-liter engine and 64km electric range is a prime example of this technology.

So, are PHEVs the right choice for you? By understanding the different powertrain options and the considerations around battery size and efficiency, you can make an informed decision. Remember, PHEVs offer a great balance between electric driving and the security of a gasoline engine for longer journeys.
