Introduction of Toyota Hybrid Electric Vehicle, Advantages and Disadvantages of Hybrid Electric Vehicle-Introduction
Undoubtedly, this is a new word in the last two years, and it is also the slogan of Toyota hybrid electric technology in China market, but it has been nearly 20 years since Toyota introduced this technology. In other words, Toyota is more like an "old brand" of car hybrid technology. Just as we buy specialties and choose restaurants, time-honored brands often mean better quality, reputation and trust. According to this, if hybrid vehicles are produced in the form of HEV parts imported from Japan in 2005, it will be 65,438+00 years since Toyota introduced this technology to China.
Toyota Prius, the representative of Toyota Hybrid Vehicle, has developed to the fourth generation, and the second and third generations have also been introduced to China.
Toyota Prius, which is widely used in taxi industry, has verified the reliability of Toyota dual-engine hybrid power system through high-intensity use.
In fact, Toyota's hybrid technology is indeed more reliable than originally expected. Not only did 18 not have any common faults when it was put into the market, but even the battery packs and motors used did not have definite problems of electric leakage and electric shock, and then some "extreme" news came out from time to time. For example, Andrew, a taxi driver in Canada.
Grant bought a Prius and put it into operation in 2004. Until the vehicle was "retired" in 20 12 years, the total mileage was10.5 thousand kilometers, but the battery and overall performance were still in a good level, which may be unimaginable in many traditional gasoline vehicles.
The early power company Chengdu was imported from Prius, which was expensive, but the market response was not enthusiastic. According to Toyota's plan to promote dual-engine technology in China, in order to let more consumers in China enjoy Toyota's hybrid dual-engine technology, on the premise of fully ensuring the quality, the core components of the hybrid system, such as drive battery, motor, power control unit (PCU) and Atkinson cycle engine, are all produced locally, thus greatly reducing the cost of hybrid vehicles. Strive to achieve the goal of "making more consumers willing to choose dual engines even compared with traditional power models of the same level".
Introduction of Toyota hybrid vehicle, advantages and disadvantages of hybrid vehicle-advantages and disadvantages of hybrid vehicle
Advantages:
1. After adopting hybrid power, the maximum power of internal combustion engine can be determined according to the average required power. At this time, it works under the best working conditions of low fuel consumption and less pollution. When the high power required by the internal combustion engine is insufficient, it is supplemented by the battery; When the load is small, the surplus power can generate electricity to charge the battery. Because the internal combustion engine can work continuously and the battery can be charged continuously, its journey is the same as that of an ordinary car.
2. Because of the battery, it is very convenient to recover energy when braking, downhill and idling.
3. In busy urban areas, the internal combustion engine can be turned off and driven only by batteries to achieve "zero" emissions.
4. With the internal combustion engine, it is convenient to solve the high energy consumption problems such as air conditioning, heating and defrosting encountered by pure electric vehicles.
5, you can use the existing gas station to refuel without investment.
6, can keep the battery in good working condition, without overcharge and overdischarge, prolong its service life and reduce the cost.
Disadvantages:
Long-distance high-speed driving can hardly save fuel. Price is high.
With the increasingly stringent global environmental protection measures, hybrid electric vehicles have become a focus of automobile research and development because of their energy saving and low emissions, and have begun to be commercialized. Consider a hybrid car if necessary.
