Plug-in hybrid, simply Plug-in or rechargeable hybrid on plug. These are some of the definitions with which i identify PHEV vehicles (Plug-in Hybrid Electric Vehicle), i.e. cars that have an internal combustion engine combined with one or more electric units powered by a battery of a certain capacity that can be recharged from an external socket. Accumulator that allows the vehicle to be able to travel a few tens of km with the petrol engine turned off (on average around 50-60 km).
We therefore decided to take the model as an example Opel Grandland Hybrid4 to better understand how this technology works inside the German SUV.
Many identify the Plug-in system as the perfect “bridge” between the endothermic and the electric. No autonomy anxiety as in the “pure” electric ones given the presence of the internal combustion engine. Thanks to the electric motor and the battery of a certain capacity (usually around 10-15 kWh) people can get used to driving in electric only for several km and above all a manage autonomy and recharge.
The general operation scheme is very simple. Thermal and electric motor can work together as in Full Hybrids. However, thanks to the Plug-in battery, the electric powertrain can provide traction to the car for a few tens of km, leaving the internal combustion engine off. Usually, drivers have different operating logics of the hybrid system available to choose from to prioritize electric drive, performance or battery charge conservation.
Obviously there is always the regenerative braking which, in some models, can be managed thanks to the availability of different levels of energy recovery. Hybrid technology also makes it easier to bring all-wheel drive to cars. For example, an electric unit will suffice for each axis without having to resort to more complex, bulky and heavy solutions. In some cases, the Plug-in technology can be a solution to make a greater level of power available without having to focus on more powerful internal combustion engines but with significantly higher consumption.
Using correctly Plug-in technology (always recharging), especially in some areas, such as city driving, it is possible to significantly reduce consumption.
What is the difference between a hybrid and a plug-in hybrid?
Sometimes there is a bit of confusion when talking about the Plug-in as in some contexts the term “hybrid” is generically used. This can lead people to think that hybrid technology is always the same. Obviously it is not true. The hybrid, whether Mild Hybrid or Full Hybrid, is always characterized by the internal combustion engine that recharges the battery (also through regenerative braking). In the Plug-in models, on the other hand, the accumulator can always be recharged even through a power socket or a public column.
Another clarification should also be made. It is often thought that Plug-in technology is only available to cars equipped with a petrol engine. Instead, there are, although not many, PHEV models equipped with a diesel engine. Think, for example, of the Mercedes GLE 350 de 4MATIC Plug-in hybrid.
What happens if I don’t charge a Plug-in hybrid car?
As mentioned above, a Plug-in car must be used correctly in order to achieve the best possible efficiency. In fact, by not filling up the battery with energy, the internal combustion engine will start working more while driving with the obvious consequence that consumption will increase.
To make the most of these cars, it is important to have a power outlet in the garage. In this way it will be possible to fill up with energy in the evening to find the car ready and charged the next morning.
How much do plug-in hybrid cars pay for tax?
This technology offers a number of advantages, including fiscal ones. In fact, hybrid cars (not just Plug-ins), depending on the Region, do not pay the stamp duty in the first 5 years.
What are the disadvantages of a plug-in hybrid car?
The main one is the cost. These models, in fact, have a high price. Additionally, their more complex technology can lead to more expensive coupons. The Plug-ins, due to the presence of the electric motor and the battery, weigh a lot and this can reduce their efficiency if the recharge and therefore the electric motor are not used.
Are there discounts for plug-in hybrid cars?
The Government has provided incentives for the purchase of these cars equal to 2,000 euros without scrapping or 4,000 euros with scrapping. The new car, however, cannot cost more than 45 thousand euros + VAT. Furthermore, hybrid cars can have access in restricted traffic areas where endothermic models cannot circulate.
