Take a look at the difference between new energy vehicles and traditional cars!

The basis of a new energy vehicle is still a car, only the form of energy that drives the vehicle has changed. Therefore, to understand the new energy vehicles, you must first have the basic knowledge of traditional cars.

New energy vehicles basic structural features and fuel vehicles are not very different, indicating that the new energy vehicles are based on some of the systems of the traditional car, improve the power to drive the car, such as the use of power batteries for storing electrical energy plus motor, or continue to retain the internal combustion engine, but optimize the combustion of combustion engine by adding a set of electric power to drive the hybrid power.

1. Changed the form of power to drive the vehicle

If it is a pure electric car, then the power to drive the car is all dependent on the motor, the motor drive power from the power battery installed in the car. The drive system of the new energy vehicle no longer has the internal combustion engine and transmission of a traditional car, but instead has a power battery located at the rear, and a drive unit with an electric motor located in the position of the original internal combustion engine (also known as the transmission).

If it's a hybrid, it will continue to see the drive system that has the components of a conventional car's internal combustion engine and transmission, but there will be a few more components on top of the ones that drive it, and that's where the added electric drive system comes in. The front engine compartment of the vehicle will still have the internal combustion engine, but there will be a distinctive orange cable connecting to the internal combustion engine, as well as a power cell located at the end of the cable, which is the typical structure of a hybrid vehicle drive system that is a combination of an internal combustion engine and electric power.

2. Retaining most of the parts of a traditional car

Whether it's a pure electric car or a hybrid car, it's hard to tell the difference from the appearance of the vehicle, because these new energy vehicles are still cars, and the improvements are only in some unseen places. Traditional fuel vehicles and hybrid new energy vehicles, from the appearance of the hybrid is not obvious to see the difference between the characteristics.

It should be noted that new energy vehicles have a similar body design as well as the basic design elements of a car, such as the driving system, braking system, steering system, body electrical appliances, etc., compared to traditional cars.

3. Because of the changes in the drive system and operation mode, some of the systems of the whole vehicle have also been upgraded

The power source of new energy vehicles is no longer just the internal combustion engine, so although new energy vehicles are born on top of traditional vehicles, some systems of new energy vehicles are different from those of traditional vehicles, such as the air conditioning and heating system, the power generation system, and forms of energy refueling.

(1) Air conditioning power source and warm air heating method is different

New energy vehicles air conditioning compressor is generally directly driven by the motor, different from the traditional automobile through the internal combustion engine crankshaft belt drive form.

In the form of warm air realization, due to the new energy vehicles do not have the internal combustion engine more than 70 degrees of heat source, the drive motor to produce heat and can not reach, most of the pure electric vehicles are usually the use of electric heating to generate warm air. Among them, there are two ways of electric heating, one is through high-voltage electric heating similar to the traditional air conditioning and heating system in the coolant, and then through the cycle to provide heat for the warm air tank; the other is directly through the high-voltage electricity to drive the PTC heater to heat the air through the evaporator box to achieve warm air.

The PTC, also known as the warm air heater, is an acronym for positive temperature coefficient heater. It is the main source of hot air for automobile manufacturing, the biggest advantage of PTC is the fast heating speed, high temperature (controllable), easy to use, this part is installed inside the warm air evaporator box assembly.

(2) Different power sources to supply power to the whole vehicle body electrical appliances

New energy vehicles are usually no longer installed with generators, and the electricity for on-board electrical equipment and the charging of 12V batteries are provided by the power batteries (high-voltage batteries) on the vehicle. For example, during operation of a pure electric vehicle, the power battery is converted from high voltage to low voltage 12V through a DC/DC converter to provide 12V power for the battery and on-board electrical appliances.

(3) Different forms of supplemental energy

If it is a pure electric vehicle, the energy of the traveling vehicle is mainly through the external power grid to provide electricity, while if it is a hybrid vehicle, the energy of the traveling vehicle has the power from the grid, but also the fuel used in traditional cars, which is different from the traditional automobile just relying on fuel to drive the vehicle.
