Hanergy solar car:
1. Solar cars are now gradually being promoted. Hanergy has signed strategic agreements with Audi, BAIC New Energy, China FAW, Rich and other manufacturers to provide automotive sunroof solutions.
2. Users can customize 3.5-7.5 square meters flexible film components according to their needs, in good weather, with 5-6 hours of light, they can travel an average of 80 kilometers per day, and are suitable for short periods. -remote vehicles. ;
3. Solar cars do not need charging to recharge. They can last indefinitely using sunlight and their key technology comes from conversion efficiency. light energy into electrical energy;
< p>4. Currently, the highest conversion efficiency of solar photovoltaic power generation in the world comes from gallium arsenide double junction cellsfrom Hanergy, which have a peak conversion rate of 31.6%. first in the world.Millions in car purchase subsidies
How to see Hanergy's all-solar electric car
It is reported that Tesla's premiere When the Cybertruck electric pickup truck is officially delivered in the second half of 2021, it will become the world's first mass-produced solar pickup truck.
Judging from the Cybertruck's intimidating appearance, the horizontal, vertical and angular design are conducive to installing solar panels. Perhaps it is at least technically easier to implement than the Model 3 Musk had hoped for. . Musk has previously said he hopes to use solar power to add 15 miles or more of cruising range per day, and if solar swing doors can be added, it would be better to reach 30 to 40 miles.
The ideas are good and we have no shortage of them. ButWhen it comes to solar energy, the first thing Che Yunju thinks of is the real application:
We are already used to gadgets such as solar water heaters, solar calculators and watches solar. the solar-powered car? Electric vehicles seem a bit far away.
Give the car some photosynthesis
Solar energy is so good that it is inexhaustible, and there is energy when you bask in the sun, a low cost example.
If we hadn't been incapable of photosynthesis, we would have saved money on meals, everyone would be a little green man, and we wouldn't have to wear the Guoan uniform for go to workers' sports. .
It's a pity that people are like rice and steel, you can't rely on the sun.
In addition, we have worked hard to use solar energy, including cars. Whether it's some of the big oness car manufacturers that we currently know or unknown startups, they have all developed or have developed solar cars.
The first solar-powered cars were in the 1970s, but they were virtually impossible to drive. Later, they gradually became public, and it hasn't been around for a very long time.
For example, in 2010, the Toyota Prius, the most famous hybrid car, allowed car owners to choose solar panels, capable of converting solar energy to charge the vehicle's battery. Although this option was later canceled, it was brought back online in 2017 and can charge the power battery directly, but on average this only adds 3 to 4 kilometers per day.
Of course, Toyota has not abandoned solar energy. She is still testing the latest solar system on the Prius. It would have increased the conversion rate to 34%, whichi can extend battery life. about 50 kilometers on a sunny day. Ultimately, this seems quite practical.
In addition to Toyota, Korean automakers also like to tinker with new energy sources. Last year, South Korea made its public debut and launched a hybrid version of the Sonata with a rooftop solar charging system. However, with 6 hours of sunlight, the increase in daily mileage was essentially 3 to 4 hours. that more advanced second and third generation products are still under development.
It is also understandable that solar energy is not the area in which these traditional automakers are primarily investing their energy, but that some startups are specifically targeting it.
For example, the German company Sono? Motors, created in 2012, has developed its first solar electric care, Zion. A total of 7.5 square meters of monocrystalline silicon solar cells on the roof and around the body. can be used under sufficient sunlight conditions. It can provide up to 34 kilometers of range per day, and in European weather conditions it can increase the range by 10 kilometers on average. The Sion will be produced at the former Saab factory in NEVS, with deliveries expected to begin in 2022.
For another example, another Dutch company, Lightyear, also launched its first vehicle last year solar electric, Lightyear One, designed by former Pininfarina designer Lowie Vermeersch. It is covered in 1,000 solar panels all over its body. It is said that solar energy converted per hour can increase the range by 12 kilometers, which is very efficient. The car is equipped with a 60 kWh battery, with a maximum range of 724 kilometers, and delivery is expected to be costart in 2021.
The Chinese are not inactive either. The loudest and most ambitious was Hanergy, whom Che Yunju once interviewed. They are betting on thin-film solar cells. They have also manufactured various large-scale solar cells. acquisitions of foreign technology companies and domestic companies. Build factories to promote solar energy. However, due to the delay in bringing the product to market and various other reasons, Hanergy is no longer what it used to be and the dream of solar cars cannot come true at the moment.
However, the Chinese people are great and there are the most outstanding people among the people. How can our various wild scientists not understand solar energy? For example, this:
And for example:
For just 20,000 yuan, you can own a solar car that can increase the range by 30 kilometersres with 8 hours of lighting and a lifespan of 30 years of car. Of course, it is not certain that this is a serious car.
The biggest promoter may still be Musk
It seems like solar power is nonsense no matter how you look at it, but we also forgot one old handsome guy and an electric car Internet celebrity. Things that seem too far away and impossible are not necessarily certain in Musk's eyes.
Musk, whether it is the first Zip2, SpaceX in the sky, The Boring Company on the ground, or Tesla today, no one can succeed at a glance. As early as 2006, Musk had already developed his vision in his mind, needless to say, electric vehicles were closely followed by solar energy. The chessboard behind is still very complicated.
What can only be mentioned here is Solarcity. The start-up capital of this solar company, co-founded by the twoMusk's cousins, was also provided by Musk that year, so she can be regarded as one of Musk's "sons".
From solar product distribution to self-research and production, Solarcity became the second largest supplier of solar products in the United States in 2013. However, it was on the brink of collapse. bankruptcy due to overexpansion and reduction of government subsidies. , and finally closed. It was acquired by Musk in 2016.
Although Musk did not intervene too much in the development of Solarcity at first, once the acquisition was finalized, the solar business naturally became part of the Tesla's entire energy strategy, and the departure of many Solarcity executives has also accelerated. has entered the “muscleification” process.
Whether it was a coincidence that Solarcity was acquired due to mismanagement, or that Musk always had a planacquisition of Solarcity, there is no denying that solar energy is an important part of Musk Connect's ideal energy ecology. domestic electricity storage, electric vehicles and power grids in one system.
After that, in recent years, as Musk worked hard to obtain the production and sales of Model 3, he actually solved the product design of the future main solar roof of the solar product at the Production problems at the New York Gigafactory. Finally, in the third quarter 2019 meeting, Musk estimated that the third generation solar roof, a qualified product, could finally be launched this year.
Of course, the idea of combining electric vehicles with solar energy has been around for a long time. Musk first wanted to try it with the Model 3, and “ordered” engineers to implement it quickly. Later, due to installation and conversion rate,for technical reasons, this idea did not take shape.
But to interrupt, designer BradBuilds built an apocalyptic-style solar-powered Tesla based on the Tesla Roadster, which looks like this:
So in comparison, this time , the Cybertruck does it. seem more suitable, and perhaps the possibility of accessing solar energy was considered from the start of the design.
But it reflects another important signal. Now that the energy sector has matured, Tesla's focus has begun to adjust.
Musc said the main goal of Tesla and Solarcity is to accelerate the use of sustainable energy, and that Tesla's future energy businesses will be comparable to those of automobiles. US head of Tesla Online, roofs and solar panels were listed alongside currently mass-produced electric vehicles in the navigation barn at the top of the site, while on the official national website Cybertruck, Roadster and Energy, which focus on the solar energy sector, are also listed. listed in the same position.
From this perspective, Tesla said: "We don't sell cars, we are an energy company."
Cheyun Summary
As electric vehicles become more and more common on the streets today, the auxiliary charging problem has always been one of our biggest problems. Solving the recharging problem is even fundamental. . Solve battery life anxiety. Therefore, apart from seeing more charging stations with faster charging, this has also given rise to more methods such as under-car wireless charging, battery swapping, road charging and solar charging mentioned today. However, from the current point of view, it still remainsore has a long way to go technically in knowing how to use solar energy effectively, and it will depend on more Musk to complete the breakthrough.
This article is from the author of Autohome Chejiahao and does not represent the views and positions of Autohome.
Look at the parameters of the car: the body is integrated with about 3.5 to 7.5 square meters of flexible gallium arsenide thin film batteries under the conditions of 5 to 6 hours of light. the average daily electricity generation is 8. When the temperature reaches 10 degrees, the car can travel about 80 kilometers and more than 20,000 kilometers per year. For long-distance travel or when there is no light, Hanergy's all-solar vehicles are equipped with conventional rechargeable lithium energy storage batteries, with a maximum range of 350 kilometers.
To speak franklyement, it is still an electric car, with an ideal maximum range of 350 kilometers. It is indistinguishable from most new energy vehicles currently on the market. As for Xinjia's thin-film power generation. , I personally think that the concept of promotion is more significant than the actual meaning of use, that is, ordinary families are completely unable to meet their car needs. Let's talk about it in a few years. Traditional cars are still the best cars. The only ones that I think can be experienced or trusted are the hybrids. There are only a few national brands. True hybrids are still small Japanese cars that don't need to be recharged at all. They simply use oil to produce electricity with reasonable deployment, saving fuel. , time and comfort.
