Hybrid means that the car uses both gasoline and electric drive. The advantage is that when the vehicle starts to stop, the motor only drives, and does not reach a certain speed, the engine does not work, therefore, the engine can be kept in the best working condition, the power is good, and the discharge is very low. And the source of electrical energy is the engine, just add fuel.
As the measures for environmental protection in the world are becoming more and more strict, there are more and more alternatives to fuel-engined vehicles, such as hydrogen energy vehicles, fuel cell vehicles, and hybrid vehicles. But at present, the most practical and commercially viable model is hybrid vehicles.
The key to a hybrid car is the hybrid system, whose performance is directly related to the overall performance of the hybrid car. After more than ten years of development, the hybrid system assembly has evolved from the original engine and motor discrete structure to the integrated structure of the engine motor and gearbox, namely the integrated hybrid powertrain system.
Hybrid powertrains are classified by power transmission route and can be classified into three types: series, parallel, and hybrid.
The power system of a hybrid electric vehicle is mainly composed of a control system, a drive system, an auxiliary power system, and a battery pack.
Hybrid working principleAt the beginning of the vehicle, the battery is fully charged, its energy output can meet the requirements of the vehicle, and the auxiliary power system does not need to work;
When the battery power is lower than 60%, the auxiliary power system starts:
Due to the presence of the battery pack, the engine is operated in a relatively stable condition, resulting in improved emissions.
Not all hybrid vehicles rely on electric motors, batteries and wires. Some vehicles are driven by the combined action of a hydraulic engine and an accumulator.
The recent price of gasoline has reached a record high, leaving consumers standing in front of the pump tremble. However, compared with the operators of heavy truck transport fleets, the pain of these consumers can only be considered a minor pain.
From a fuel economy point of view, trucks that deliver packages and deliver garbage to us need to suffer several adverse effects. Weight is one of the major factors. Fully loaded heavy-duty transport vehicles typically range in weight from 14,000 to 33,000 pounds. In addition to weight factors, many of these vehicles also have a fuel-burning duty cycle that requires constant starting and stopping.
The most aggressive of these hydraulic hybrids is completely free of the traditional mechanical powertrain. In these vehicles, the diesel engine drives the hydraulic pump engine, which in turn stores the high-pressure accumulator. The accumulator drives a tilting shaft hydraulic motor on the rear wheel to drive the vehicle. A low pressure reserve is used to collect the liquid and then return the liquid to the first hydraulic pump engine, thus forming a complete hydraulic circulation system.
Like electric hybrid engines, hydraulic hybrid engines also have the ability to provide regenerative braking. Cargo transportation vehicles and muck transport vehicles often brake the brakes. When the vehicle brakes, the hydraulic pump engine stores energy for the high-pressure accumulator. When the truck is started again, the energy stored in the accumulator can be used to reduce the load on the diesel engine. This energy can also limit the burst of propulsion during engine shutdown, for example, when operating a vehicle indoors.
For the average consumer or some engineers, in such a world of increasing electrification, hydraulic engine technology seems to be somewhat outdated. However, hydraulic pump engines and accumulators provide a reliable, low-cost way to apply torque and stored energy, which is what hybrid vehicles require. And hydraulic engines have a significant power density advantage over electric systems, at least for now.
Hybrid advantageHybrid vehicles have high fuel economy performance and superior driving performance. Hybrid vehicles use fuel oil, and when starting and accelerating, they can reduce fuel consumption due to the assistance of electric motors. Simply put, they are the same size. Compared to cars, fuel costs are lower.
Moreover, the electric motor of the auxiliary engine can generate powerful power at the moment of starting, so the owner can enjoy a more powerful start and acceleration. At the same time, a higher level of fuel economy can be achieved
The "Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)" (hereinafter referred to as "Planning") issued by the General Office of the State Council clearly clarifies that hybrid vehicles are energy-efficient vehicles.
Hybrid systems are divided into plug-in and plug-in. The plug-in hybrid car has a relatively large battery capacity and can be externally charged to drive a long distance with pure electric power. This feature is not available for plug-in hybrid systems.
Note that in the national regulations, only plug-in hybrid models belong to new energy vehicles. Non-plug-in hybrid cars, such as Corolla Twin Engine, Accord Hybrid, etc., are not considered new energy vehicles!
The “Energy Conservation and New Energy Vehicle Planning†divides the development of the two types of vehicles into industrial cultivation period and industrial maturity period. It is clear that the industrialization and marketization of new energy vehicles are still constrained, and energy-saving vehicles are more likely to be commercialized on a large scale.
“Planning†makes a strict distinction between new energy vehicles and energy-efficient vehicles. Hybrid vehicles are classified as energy-efficient cars.
According to the “planâ€, a new energy vehicle refers to a vehicle that is driven by a new type of power system that is wholly or mainly driven by new energy sources. It mainly includes pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles.
Energy-saving vehicles refer to vehicles that use the internal combustion engine as the main power system and the fuel consumption of the comprehensive working conditions is better than the target value of the next stage.
The “next phase target value†mentioned in “Planning†means that by 2015, the average fuel consumption of passenger cars produced in that year fell to 6.9 liters/100 kilometers, and the fuel consumption of energy-saving passenger cars fell to 5.9 liters. /100 kilometers or less.
Is hybrid worth buying? worth buying:1, driving experience
Due to the fast response power source of the motor, the hybrid car is generally better than the same class of fuel car. Medium and low speed overtaking is more agile.
2, air conditioning
Winter heating is much faster than fuel vehicles and is especially friendly to users in cold regions. In addition, there is no need to open the engine for cooling and heating, and the experience is great (provided the battery is large enough).
3, quiet
In many cases, it is possible to drive in pure electric mode.
4, fuel economy
It can't be said that every hybrid car is fuel-efficient than the traditional car of the same class. It can only be said that most cars are fuel-efficient.
