Since 1997, the world’s first mass-produced hybrid car was launched on the Japanese market. Hybrid cars have been available for nearly 20 years. With more independent brands testing this area, and the originator of hybrid technology, Toyota began to produce hybrid vehicles in China, and hybrid technology has entered a period of rapid popularity in China. But do you really understand hybrid power?
Is the hybrid car different?
Some hybrid electric vehicles are driven by pure electric power, such as low speed or idling, when there is no engine noise, the vehicle will be very quiet. In terms of space for occupancy, after years of development, the latest hybrid devices have been greatly reduced in size and weight, and the layout has become more ingenious. For example, the motor is integrated into the transmission system, and the battery pack is hidden in the trunk and rear seats. Between chairs, etc., so the seating space is basically not affected, only the volume of the trunk will be compressed.
Due to motor-driven reasons, hybrid vehicles can compensate for the problem of insufficient torque when the engine is running at a low speed. As a result, the acceleration of the entire vehicle will be more even. This is why Ferrari, McLaren, Porsche and other manufacturers are all at the flagship level. The reason why hyper-running uses hybrid technology. In addition, for the increase of the weight of the vehicle and the change of the weight, the manufacturers also adjusted the stiffness of the front and rear springs, and the shock absorbers were re-matched. Therefore, the controllability of hybrid vehicles is not very different from that of ordinary models.
Does the hybrid need to be charged?
Maybe it was because I heard that the hybrid power unit contained a battery pack, perhaps because of confusion with the plug-in electric vehicle. In short, many people think that the hybrid vehicle needs to pull wires from the trunk from time to time and insert it on the wall. The outlet is charged before it can run. If that is the case, I believe most people will dispel the desire to buy a hybrid car. However, in fact, this is a serious misunderstanding. The big mistake is that I have seen some hybrid vehicle manufacturers put up a large amount of advertisements for positive viewing. It clearly states that hybrid vehicles do not need to be recharged.
In fact, there are doubts that you don't know enough about the working principle of hybrid vehicles. Hybrid energy recovery devices convert excess kinetic energy or the output of the engine into electrical energy during braking, high-speed cruising, etc. Among the batteries, these electric energy will then be used instead of the engine to provide power to the vehicle during the low speed phase of the vehicle, or to cooperate with the engine to output more power when the vehicle needs to be started quickly. In the new generation of the Lexus hybrid system, the time for the motor to participate in the work becomes variable. To be longer, the internal combustion engine can also operate at relatively lower speeds during high-speed cruising. For example, in the ES300h model, due to the extra power available from the motor, the gasoline engine speed at cruising at 100 km/h is only 1600 rpm. This is The traditional models are difficult to achieve low speed. The combination of various factors has created a fuel economy advantage for hybrid vehicles under various operating conditions.
How much oil can a hybrid vehicle save?
The most important feature of hybrid vehicles is fuel efficiency. The official fuel consumption of the twin engines is 4.2 liters per 100 kilometers, and this figure is not a theoretical value. They can be achieved during actual use. For example, the official 100km fuel consumption of the Camry Shuangqian is 5.3 litres. In actual use, the actual fuel consumption can reach less than 5 liters per 100 kilometers. Based on the previous usage, the average fuel consumption of hybrid vehicles will be 30%-40% lower than that of gasoline vehicles with the same displacement.
Is the battery easily broken?
At present, all the Toyota-listed hybrid models on the domestic market have a battery warranty period of at least 8 years/200,000 kilometers, and some Lexus models have even reached 10 years/25 million kilometers. This long warranty seems to be due to the sincerity of the manufacturers. On the other hand, Toyota's confidence in its own technology can also be seen. The facts over the years have proved that the chances of damage to the battery within 10 years are very small. In some regions that use hybrid vehicles as taxis, the highest record is 900,000 kilometers before the battery needs to be replaced! If you calculate according to the annual driving volume of 20,000 kilometers of domestic cars, it can be about 45 years! Of course, I believe no one wants to go so long. In addition, the privately-owned factory staff said that this kind of super-long warranty appears to be a sign of sincerity, but in essence it is self-confidence, because Lexus knows that the probability of hybrid battery damage within 10 years is small and small.
Is a hybrid car safe?
Although the world’s most advanced Boeing 787 passenger aircraft have been grounded several times due to the spontaneous combustion of lithium-ion batteries, you don’t need to worry about the spontaneous combustion of the Toyota family’s hybrid vehicles because they use a stable nickel-metal hydride. Battery.
Hybrid vehicles, like ordinary models, must meet various safety standards and participate in major collision tests, so their safety is not different from that of ordinary models. In terms of electric drive systems, Toyota's hybrid vehicles use nickel-metal hydride batteries, which are much safer than lithium batteries. Since the first Prius was launched in 1997, Toyota's hybrid models have sold more than 8 million vehicles. There have been no accidents such as battery burning, leakage, or electric shock. What is even more powerful is that in 2011, Japan experienced a particularly tsunami attack. There were countless Toyota hybrid vehicles that had been flooded. There was still no electric shock.
High maintenance costs for hybrid vehicles?
Unlike an internal combustion engine, a hybrid system consisting of a battery pack and a motor is maintenance-free. It is not necessary to change oil, water, or anything every few thousand kilometers. Therefore, it is unnecessary to worry about whether hybrid vehicles will be expensive to maintain. of. For Rachel Twins, their maintenance is basically the same as that of regular gasoline models, and the vehicle also offers a long 5-year/140,000-km warranty, while the battery part provides 8 years/200,000 kilometers. The warranty period, during this period, if there is a problem with the battery, the manufacturer will warranty even a free replacement of the new battery. In addition, Lexus offers leading 6-year/150,000-km free warranty and free maintenance service for its hybrid models, which makes people no worries! In addition, Lexus owners also talked about, Lexus accompanied by free car warranty gold content is particularly high, even the hub damage such as car insurance are not covered by the project have been included in the scope of free warranty.
Hybrid car compartment space is small?
Indeed, at the beginning of hybrid vehicles, hybrid vehicles and battery packs take up a lot of space, so the hybrid car space will be relatively narrow. In fact, the first generation of hybrid vehicles are basically designed vehicles, in order to accommodate this huge hybrid system. However, with the advancement of technology, the current hybrid power plant is no longer comparable. If it is desired, Lexus or Toyota can transform almost any of its vehicles into hybrid models because a new generation of hybrid power plants is required. Both weight and weight have been greatly reduced. Take the ES300h for example. Looking at the car alone, it is exactly the same as the regular ES250 or ES350. Opening the trunk, weird, it seems that there is no difference. So where did the pile of batteries and motors go? Through clever distribution, the motor is integrated into the transmission system, and the battery pack is hidden between the trunk and the rear seats. The normal use is almost unaffected. Only the volume of the trunk is slightly sacrificed. Dozens of liters.
Will the hybrid be out of date quickly?
It has always been the case that hybrid technology will exist as a transitional technology before the real replacement energy has been established. It sounds like there is a certain truth: Now that cars burn oil, and the future cars use electricity, it seems that the hybrid technology, which uses both oil and electricity, is a so-called transition. But hybrid technology is by no means flashy, even if there is a future for replacement energy.
We have to sort out a concept. Although the current hybrid car is basically a hybrid engine and electric motor with the program, but in fact it is only one of a combination of hybrid technology, and hybrid, not so much a technology, it is a A solution for managing two powered vehicles. Just in dealing with this dual power technology, Lexus and even Toyota have the best technology accumulation. Since hybrid power is not limited to fuel-electric hybrids, on the day when alternative sources of energy appear in the future, the position of internal combustion engines can now be replaced by hydrogen fuel cells or even some sort of alien technology. The principle of hybrid power plants remains the same. It is like the peak of electricity, collected as electrical energy when there is excess kinetic energy, and the electrical energy is released when kinetic energy is needed. So, hybrid technology is promising!
