We are all familiar with gasoline cars and most people have heard or seen in electric cars. A hybrid car is a combination of both. A hybrid vehicle contains parts of gasoline and electric vehicles, an effort to get the best of both worlds.
The best way to understand the benefits of a hybrid car is a car driving on a flat road speed limit. In this case, the motor will perform three activities:
1 It is to overcome rolling resistance in the drive system; 2 It is the overcoming air resistance; 3 It's feeding accessories such as the alternator, power steering pump and air conditioning.
The engine can be a maximum of 10 to 20 HP power to produce bear the weight. The cars have to handle engines with 100 or 200 HP acceleration from standstill, and overcoming and uphill. We use the maximum power of only 1% of the route. The rest of the time we carry the weight and friction of a much larger engine, which wastes a lot of energy.
In a traditional hybrid vehicle, you need a full electric car. It has an electric motor to all power to the wheels as well as batteries to supply power to the motor. Then you have a petrol engine a generator power completely separate. The engine is very small (10 or 20 hp) and was designed to work only with a speed that seeks maximum efficiency. The purpose of this small and efficient engine to provide enough energy for the vehicle at cruising speed. During periods of acceleration, the batteries provide the additional energy needed. If the car is slowed or stopped, charge the batteries. This type of hybrid car is essentially an electric car with an on-board charger for longer range. The advantage is that these small gas engine and efficiently develop a great car.
The only problem with a traditional hybrid car is the weight. The car has to carry the weight of the electric motor, generator, gasoline engine and batteries. You do not need as many batteries as a pure electric car, and it ends up saving a little weight, but the full electric motor and a 10 kW generator can weigh much.
The Honda Insight particularly trying to define an "in between". It uses a larger gas engine is connected directly to the drive, along with an electric motor, with the motor. The gasoline engine of the vehicle is the most energy, and the electric motor provides additional energy required for the acceleration. Since the electric motor work as a generator during braking and only a part time work, it is extremely easy. The disadvantage of this approach is that the gasoline engine must at different speeds, which turn reduces their efficiency.
