How Do Hybrid Cars Work?
The Hybrid Electric Vehicle (HEV) is quite a marvel. Even as a work in progress, it has improved the gas-dependence situation and has saved many from having to spend so much on fossil fuels and has even helped save some taxpayer money.
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.
What’s In 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.
Go The Distance
In order to actually see how a hybrid car works, one would have to take one for a spin on a full tank and compare the results in mileage with a car that runs only on gas. One will definitely see the huge difference in cars dependent on electric motors. Going a great distance is achieved by the way the hybrid works. There are 3 essential technologies that allow this to happen.
The first innovative technology used in hybrid cars is the regenerative braking that applies resistance to the drive train. This in turn causes the wheels to slow down. The energy from the wheels turns the engine which in real time acts as generator which converts the energy wasted during coasting and braking into electricity. The electricity is then accumulated in a battery until such time when it is needed by other functions in the electric motor.
The next technology is known as elect motor assist and it provides additional power to assist the engine in acceleration like when speeding up or ascending. This means that the smaller engine (electric motor) is used and is more efficient than an internal combustion engine that requires and burns a lot of 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.
