The Hybrid Electric Vehicle (HEV) is quite the technological wonder. As a work in progress, the Hybrid Electric Vehicle technology has done much to improve the gas-dependence situation and has saved several households and individuals from having to spend so much on fossil fuels.
So what is it under the hood that is creating all these wondrous things that seem to improve the lifestyle of the average consumer? Let's take a look at how hybrid cars work.
The Combination
The keyword in all of this is the word "hybrid." An HEV basically brings out the best in both electrical power and fuel. By incorporating both an electrical motor and a gas engine, it allows the vehicle to switch back and forth between energy sources. Of course, the usual case is that the car really depends solely on the battery and electrical motors to run the vehicle.
You may ask what the gas is for. The car will still need gas to operate an engine that charges the battery which, in turn, runs the whole car. However, the good thing about this set up is that not much gas is required to charge up those batteries. Hence, hybrid cars really only need so much gas to fill their significantly smaller gas tanks and therefore saves people from having to cash out so much on gas.
The Distance
To understand how a hybrid car really works, you would need to take one for a spin on a full tank and compare the results in distance and mileage with a vehicle that runs on gas alone. Definitely, you will observe the world of difference in vehicles running on electric motors. Running great distances is easily achieved in the way how a hybrid car works. There are basically 3 technologies that makes this possible.
The first is known as regenerative braking and this involves an electric motor that applies resistance to the drive train which causes the wheels to slow down. The energy from the wheels turns the motor which in real time acts as a generator which converts energy wasted during coasting and braking into electricity. That electricity is then stored in a battery until it is needed by functions in the electric motor.
The next hybrid car technology used is the elect motor assist which gives additional power to aid the motor in acceleration like in speeding up or ascending higher terrains. This simply means that the smaller engine or electric motor is used. This motor is more efficient that the internal combustion engine that needs and uses up more gas.
Another technology that is starting to pick up in a lot of modern hybrid vehicles is known simply as automatic start and shutdown. When a hybrid vehicle stops in the middle of traffic or at a stoplight, the whole engine will shutdown as well. This prevents the engine from wasting energy and fuel from just being idle. And when the accelerator is pressed again, the engine will automatically start up so that acceleration is made available. It's a nifty option that has gained popularity from city street drivers. Combine these three technologies and this is essentially how hybrid cars work.
