Since there is a lot of emphasis on hybrid cars these days, it is interesting to look at how a hybrid car works. Any vehicle that is able to work with two power sources could be called a hybrid vehicle. The simplest of the hybrids is the moped that could be pedaled or run by the engine. In a hybrid car the two power sources are the internal combustion engine and an electric motor. While the storage of power for the electric motor is provided by the battery the engine generates its power with gasoline obtained from a fuel tank.
There are two types of hybrid cars when you consider the way they work. One is called the parallel hybrid and the other is called the series hybrid. In a parallel hybrid car, both electric motor and the gasoline engine work independently. Also both are linked to transmission and both could run the car at the same time. This means in a parallel hybrid, the engine is supported by the electric motor continuously.
In contrast, in a series hybrid, there is a generator that either charges a battery or provides the power to run an electric motor. As such, the gasoline engine will not power the transmission at any time. Therefore, it will never drive the car.
When it comes to performance, the advantage with a hybrid car is that the engine could be a relatively smaller one. Therefore, the car could be made lighter to compensate the weight of the battery. Also the smaller engines are more efficient than the bigger ones.
There are several reasons for smaller engines to be more efficient than their larger counterparts. One is that they are heavier and need more power every time the car starts to run and when pulling uphill. Another reason is that their pistons are heavier and more fuel is consumed to push them up. Finally, these large engines have more cylinders and each burns some fuel.
In addition to the battery being charged by the engine, hybrid vehicles are able to charge their batteries when the driver wants to reduce speed. When you apply brakes, instead the engine driving the motor and the motor driving the transmission the transmission drives the motor. When this happens the motor will work similar to a generator and will produce electricity to be stored in the battery. This means every time you slow down the car, your hybrid car will charge its batteries.
