The smog locks the city and the oil price is high, which makes more and more consumers tend to choose new energy vehicles. However, after actually entering the market, it was discovered that the new energy vehicle is far from being as beautiful as imagined. Either the supporting facilities are not perfect, or the price/performance ratio is low, or the normal driving demand cannot be met. There are always various reasons for people to give up the idea of ​​new energy vehicles.

Even Toyota's hybrid electric vehicles, which have sold more than 6.8 million units worldwide in the 17-year period and at the end of July 2014, are also considered by consumers to be “unreliableâ€.
These "unreliable" are all caused by consumers' congenital misunderstanding of hybrid technology. Not to mention that the price of today's hybrid models is close to the traditional power models of the same class, and the hot sales in Japan and the United States are sufficient to prove the maturity and reliability of hybrid technology. Hybrids are like the smart phones that are now full of streets. They are a subversion of traditional technology. Why is it not accepted and popularized in China like a smartphone?
The reason is because "technical risk" has been over-amplified. In fact, hybrid technology is not mysterious. Let us work together to make a "big secret".
Secret one: Hybrid does not need to be charged
Obviously many people have confused pure electric (EV) and hybrid electric (HEV). When you hear a car that is "electric", it will unconsciously be classified into a pure electric vehicle with charging problems.
Unlike pure electric power, hybrid power does not need to be plugged in to supplement electric energy. Some people can't help but ask, then where does energy come from?
Toyota's hybrid system uses a portion of the engine's power to generate electricity and store it in the battery when the vehicle does not require the engine to provide high power. Moreover, the kinetic energy reduced during vehicle deceleration and braking is also converted into electrical energy stored in the battery, which is called "regenerative braking". This is the source of “electricity†in the hybrid electric power technology. The electric energy stored in the battery is fully utilized as a driving force during the running of the vehicle, that is, the fuel consumption is reduced, and the power is increased. “Electricity†achieves circulation in the hybrid electric-powered dual-engine power system, so that the hybrid vehicle can be “electrically†available without charging.
It can be said that Toyota Hybrid is trying to recycle and store some energy that would otherwise be wasted. And it's all controlled automatically by the intelligent system, completely without human intervention.
Secret 2: Hybrid battery is not so fragile
Everyone’s concerns about the Toyota hybrid battery are not unreasonable. After all, after using the battery on laptops and smart phones for a year and a half, the storage capacity will inevitably decline. Then he gave birth to the rumor that "the Toyota hybrid car will replace the battery every three years." In fact, Toyota uses the battery method and the electronic product is essentially different. The digital product battery charging basically adopts the deep charge and deep release method, that is, the low battery is used to fill the battery once, which is actually the biggest culprit of the battery life. .
Toyota Hybrid uses a shallow-charge multi-cycle strategy, which generally only uses 10% of battery capacity when driving in urban areas. Even in the most extreme cases, the maximum battery consumption is only 40%. In other words, about 60% of the battery's power is never used, which guarantees "light charging." In addition, Toyota Hybrid can recover energy during braking and taxiing, so the number of charging is quite frequent, which is called "multi-cycle". This kind of strategy can greatly improve the life of the battery, and in view of the battery of electronic devices such as notebooks, in order to ensure the use time, the discharge amount will exceed 80% of the battery capacity.
An example of the reliability of Toyota's batteries is the Prius taxis that are active worldwide. Toyota has recycled many taxis with a mileage of more than 200,000 kilometers. Among them, even the mileage of the car exceeds 500,000 kilometers. No one has replaced the battery in the middle, and even the battery failure has not happened!
Secret 3: Strong protection against electric leakage
Because the rear of the car is carrying a large battery and the output is high-voltage, many people will worry that the hybrid car will have a risk of electric leakage in the event of a collision.
Toyota has two lines of defense. First, the battery is placed on the back of the rear seat. This position is outside the rear end of the car, so even if it is caught in the rear, the body deformation is difficult to reach the battery. In addition, Toyota has designed a protective bracket for the battery. In the 80km/h rear-end test conducted in the United States, the battery of the Toyota hybrid car did not suffer any damage. In addition, Toyota battery protection has another line of defense, that is, when the airbag is ejected (ie, a serious collision occurs), the vehicle will automatically cut off the high-voltage power supply, thus extinguishing the possibility of leakage from the root.
The northeastern part of Japan suffered an earthquake and tsunami shock in 2011, and many Toyota hybrid cars were soaked in the flood. In this extreme case, there was no accident of electric shock.
Secret 4: No special maintenance with ordinary cars
Due to the extra set of electric drive system, many people will worry about the maintenance of the Toyota hybrid car, the process is more than the traditional car, the cost will rise. In fact, in the maintenance project and the interval, the hybrid and the gasoline car are the same, and they are only routine items such as changing the oil, and the electric drive system is maintenance-free for life. Take Camry Zunrui as an example. This car is in the same way as the traditional power Camry, and there is no "specialization".
To tell a real person, a Japanese reporter named Yokota Yokota drove the Prius and spent 12 years across the five continents. There are many places in the environment such as the Sahara Desert. There are no special maintenance on the road. Sometimes even the basic maintenance can not be satisfied. Some of the slightly delicate traditional power cars will be defeated. The Prius eventually accompanied Yokota Yokota to complete the journey, including the electric drive system, there was no fault in the middle of the vehicle, and even the cabin cover was not opened once!
In general, Toyota Hybrids bring fuel-saving benefits without the user having to pay for it. In the past, the price of Toyota hybrid cars was much higher than that of traditional power cars. However, after years of technical accumulation, the price has dropped to a level that is only slightly more expensive than traditional power cars. In addition to being able to return to the fuel costs You can also enjoy the quiet system, power and other aspects of the hybrid system. Therefore, the Toyota Hybrid has actually come to us. This misunderstood window paper is only a matter of time.
Nervos is an ambitious newcomer on the crypto market and Changelly has long watched it with interest. The project attracted the attention of investors and developers since its purpose is not to launch another cryptocurrency in the ecosystem. Nervos is a simple connecting database between any blockchains.
Nervos was launched in November 2019 by Nervos Network and aims to fix issues that plague both Bitcoin and Ethereum. Among them are scalability and value differences. To fix them, the Nervos team wants to implement effective scalability and raise the cost of their token by hosting other cryptocurrencies on their blockchain. Nervos supports smart contracts and is censorship-resistant. CKB is a native token of the Nervos network. It scales with the value of other assets stored on the network: the more cryptos and tokens are there, the more valuable CKB becomes. This means that this token will continue raising its value the more attention and assets it attracts. Add to that the support of smart contracts, and you have a nice crypto bridge between different blockchains. Which is exactly what makes it so attractive for both crypto enthusiasts and investors.
