At present, the main brands that produce gasoline-electric hybrid vehicles in the world are Honda, Toyota, Nissan and General Motors. Other brands rarely use gasoline-electric hybrid vehicles. Why is this so?Toyota and Honda's systems were designed with two in mind: to keep costs as low as possible and maximize profits. Reduced urban fuel consumption.
In order to achieve these two goals, they have the following design features: they use low-capacity battery packs, and the advantages of small battery packs are that they are lighter and smaller, which helps to reduce fuel consumption in cities with frequent start-ups. Use cheaper NiMH batteries. By using a motor with reduced torque, the requirements for machining accuracy are reduced, which in turn reduces production costs.
The engine performance degradation is compensated by the electric motor at short distances, and the performance degradation at long distances. Abandon high-speed performance and fuel consumption, and aim for low fuel consumption in the city. Due to the small battery capacity of this Toyota and Honda system, the engine performance is poor, driving the vehicle at a speed of more than 100 km/h for long distances will lead to a significant increase in fuel consumption.
A vehicle that is the same weight and power higher than pure fuel. When it comes to Toyota, Honda's hybrid technology and domestic plug-in hybrid technology, the biggest difference is that Japanese hybrids still use gasoline. Fuel savings can only be achieved by optimizing the operating conditions of the engine and adding the help of the electric motor.
The distance traveled on the battery alone is very short and the speed is relatively low. The principle is that both the engine and the electric motor can drive the vehicle, when the battery is fully charged, the electric motor can be used to drive the vehicle alone when starting and driving at low speeds, and when the battery is low, the engine can drive the vehicle alone. Start driving the vehicle and generating electricity, charging the battery.
When the vehicle is traveling at high speed, the engine starts driving the vehicle. When driving, the engine drives the vehicle directly. Diesel-electric hybrid is a very complex technology that not every manufacturer can produce, Audi once manufactured a batch of gasoline-electric hybrid Audi Q5, which ultimately consumes more fuel than the ordinary 20T Audi Q5.
Not to mention local manufacturers, the seemingly simple combination of electric motor and gasoline engine actually saves energy in details. Currently, only Toyota and Honda have clearly mastered the technology, while GM has a relatively low level of control, so only Toyota and Honda have economical gasoline-electric hybrids.
Precisely because there are so few brands that have mastered this technology, countries are promoting plug-in hybrid and pure electric vehicles. Today, monopolizing technology is tantamount to forcing politics to alienate you. That's why Tesla has completely opened up its technology patents to anyone, and pure electric vehicles are being used in countries around the world.
The biggest advantage of plug-in hybrids is charging. When electric, acceleration and fuel economy are good. However, when the electricity is used up, it is an ordinary fuel vehicle, and the fuel consumption will be higher than that of ordinary cars, or even higher, so it is more favorable for users who do not travel long distances on a daily basis.
And there are also many friends in the automotive industry who tell me that it is not recommended to buy plug-in hybrid vehicles now, the main reason is that the technology is not very mature, and the vehicle with the same configuration will be twice as expensive. The same is true if you add batteries. If there is no new energy license, the cost performance will be slightly lower.
Let's talk about why domestic hybrid cars like Toyota are not being developed. In fact, the main reason is that they don't have their own technology. If they want to develop similar hybrid vehicles, the main technology will be controlled by Japanese manufacturers, which discourages independent research and development.
And at present, there is no domestic subsidy for this kind of hybrid vehicle, and the manufacturer is thankless, of course, no one will do it. In general, it is not sustainable for domestic cars to rely solely on plug-in hybrids to achieve the specified fuel consumption values. Japanese cars are still available. Now, of course, people are dealing with hydrogen-powered cars and other new energy sources. I am optimistic about the plug-in hybrid developed based on hybrids.
