This is the meaning of all the acronyms around hybrid and electric cars, explaining how they work and with examples of each of them. As is well known, car manufacturers love to invent acronyms, such as ABS, stability control, traction, stability control, etc. And the best of all is that each one calls it in a different way, except for electric cars that seem to have agreed. We all know the acronym EV, HEV, BEV, FCEV, MHEV or PHEV. But what exactly do each of these mean? Whatever the reason you are reading this blog, by the end of this you will have understood each of these acronyms. EV: Electric Vehicle - Electric Vehicle This is the acronym that generalizes to all electric vehicles in a general way, but now let's go into detail, what types of electric vehicles are there? HEV: Hybrid Electric Vehicle - Hybrid Electric Vehicle The most common vehicle on the market is non-plug-in hybrid vehicles. They have two types of engines, the main engine is the combustion engine, mostly gasoline and diesel. And a second smaller electric motor that helps in certain moments such as when starting or in strong accelerations. They have the possibility of circulating in electric mode at low speed and for a few kilometers, the battery is charged through the energy recovery system during braking or speed reduction and the combustion engine alternator.
PHEV: Plug-in Hybrid Electric Vehicle – Plug-in Electric Hybrid Vehicle
These are like the previous ones, hybrids, and also pluggable. The main difference is that they have greater autonomy than the previous ones, being able to reach 50 km in electric mode with a larger battery that allows this difference, and it is precisely the main difference with respect to the previous ones. Like the previous ones, there is still a combustion engine that performs its main functions and batteries that exceed 40km of autonomy and that thanks to this they get the Zero emissions label. This difference makes it possible to enter and exit large cities without emissions, although it also increases their weight, resulting in greater fuel consumption over long distances.
These plug-in hybrid vehicles allow sufficient autonomy to circulate without emissions and engine noise. The electric motor allows to circulate at low revolutions, but when we ask the motor for more power, the combustion engine starts working and the electric motor is disconnected.
When we ask the car for a very strong acceleration, it can combine the power of the combustion engine and that of the electric, adding the powers of both engines.
BEV: Battery Electric Vehicle – Battery Electric Vehicle
They refer to vehicles whose only traction is the electric motor. Like plug-in hybrids, they have one or more electric motors and large batteries. Like these, they are also recharged with braking or speed reduction, but we also have the battery charge, plugging the car into a charger, slowly like home plugs or at high speed using fast charging plugs.
FCEV: Fuel Cell Electric Vehicle - Fuel Cell Electric Vehicle Hydrogen is used as an energy source in fuel cell cars, which is why they are commonly referred to as hydrogen cars. The fuel cell works as fuel in a process in which hydrogen is oxidized, letting electrons pass through a membrane, producing an electrical current that makes the vehicle's engines move. It is not necessary for us to emphasize that fuel cell cars do not generate polluting emissions, because what the vehicle emits is simply water vapor. They are cars with zero polluting emissions, since the gas that comes out of the tailpipe is water vapor. E-REV: Extended Range Electric Vehicle - Extended Range Electric Vehicle These types of vehicles are the least common on the market, they have a combustion engine, electric motor and battery. The combustion engine does not move the vehicle, but works as a generator producing electricity, and this charges the battery when they go down. They are very common in Asian countries, and perhaps it is the solution that gives wings to pure electric cars, since they will save us on those occasions when we find no charger at hand, giving us enough autonomy to reach the charging point. MHEV: Mild-hybrid Electric Vehicle - Micro-hybrid Electric Vehicle These vehicles have a small hybrid system that provides extra power in specific circumstances, at a voltage of 48V, being able to power some systems of this.
Hi to all, the contents present at this site are really awesome
for people experience, well, keep up the good work fellows.
This design is incredible! You obviously know how to keep
a reader entertained. Between your wit and your videos, I was almost moved to start my own blog (well,
almost…HaHa!) Excellent job. I really enjoyed what you had to say, and more than that, how you presented
it. Too cool!
