[Technology] Can the water test of solar cars stir the rivers and lakes?

Recently, according to foreign media reports, German startup Sono Motors is about to launch a MPV model called SION. The biggest attention of the car is the method of solar energy supplementation. Coincidentally, the Dutch Light -Year Motor Corporation, which was established in 2016, also recently released the world's first commercial solar car "Light Years 0".

In China, the pure solar car "Tianjin" was unveiled in July of Tianjin's West Qing District Big Data Center. It rely entirely on pure solar -driven and did not use any fossil fuels and external power supply to achieve "zero emissions".

Many companies have launched solar cars

"New Fortune of Germany" Sono Motors announced on July 25 that it is about to launch a MPV model called SION, which will be delivered to customers as soon as possible next year.

In the news, the shape of this car is not worthy of attention from the company's background to this car. The biggest attention is that the car uses solar energy supplementation. By embedded with 456 solar photovoltaic boards on the roof, it can supplement 112-245km battery life in different environments in different environments.

At the same time, this car can store 54kWh power, with a total range of 305km. In addition, the car also supports 75KW AC power, and 11kW DC power, which can also be charged in two -way.

If you are calculated by 1,000 kilometers per month and 0.5 yuan per KWH electricity bill, you can save 30-40 yuan of electricity costs through solar energy storage per month, and save about 400 yuan a year. In view of the starting price of only 25,100 euros and lower car costs, the new car may have a very bright market prospect in the future.

According to the United States Cable Television News Network, the Dutch Light -Year Motor Corporation, which was established in 2016, released the world's first commercial solar car "Light Years 0". Its roof and hoods were installed with curved solar panels.

According to the Guangnian Motor Company, the car is exposed to the sun for an hour, and the charging can be used for 9.6 kilometers. This provides convenience for people's long -distance travel, which also means that the owner spends less time at the charging station, or even There may be no charging stations at all. In addition, in the most sufficient month in the year, it will allow short -distance driving to provide power by solar energy.

For example, in hot areas such as Spain or Portugal, if someone's daily commute is less than 36 kilometers per day, it does not need to charge the battery at all in 7 months. In countries like the Netherlands, cars need to be charged after two months.

Guangnian Motor Company said the company was delivered to this car in Europe as earlier in November this year and will sell this car in the United Kingdom and the United States in 2025.

This solar car produced by Guangnian Motor Company does not require fuel nor air, and it is also a potential method to solve the problem of the lack of useful charging facilities in the electric vehicle revolution.

Earlier this year, Mercedes -Benz launched a VISIONEQXX electric vehicle. By installing solar panels on the roof, it can increase its battery life by 25km. However, it should be noted that the full battery life of this car can reach 1000km. In a 11 and a half hour test in the Alps in April, the roof solar panels increased the battery life by 25 kilometers.

In January 2022, the Mercedes -Benz Vision EQXX concept car was released. Picture source: network

In addition, not long ago, a group of students driving the solar car created by the Belgian Agora solar team set a world record, driving 1051 kilometers within 12 hours, surpassing the 924 kilometers of the Dutch solar team since 2020. However, because only one driver can be taken in the car, this car is unlikely to be sold out soon.

In addition, the APTERA Motors in the United States plans to invest in APTERA solar vehicles this year. It can be charged for about 1609 kilometers at a time. Through the built -in 180 solar panels, it can provide an additional 64 kilometers of battery life every day. Because of its unique shape, it can achieve ultra -low wind resistance coefficients and ensure lower power consumption.

It is more like a car driving an alien biological driving, especially when the night falls, it looks more mysterious. Its shape is like a aircraft without wings. There are two wheels in front, and there is only one wheel in the back. The entire body is slender, but the center of gravity is basically in the front side because there are only two seats in the front row.

The latest news shows that this car will begin production in 2022, but delivery may be postponed to 2023 or 2024.

China's first pure solar vehicle "Tianjin"

In China, there are also pure solar vehicles, and they are also the same as Shenzhou 12 technology. It is the Tianjin developed by Tianjin Alder. In addition, through the core technologies of the 42 units, the Tianjin has achieved 100%of the "Tianjin content" of key core components.

Test data shows that in the sunny weather, the average daily power generation of the "Tianjin" pure solar vehicle reached 7.6 degrees and supported a range of 79.2 kilometers.

According to reports, the "Tianjin" rely on pure solar -driven, and does not use any fossil fuel and external power supply to achieve "zero emissions". Related information shows that the solar component area of ​​"Tianjin" is about 8.1 square meters, the battery energy ratio is 330Wh/kg, and the autonomous driving level reaches L4 and above. At the beginning of research and development, the "Tianjin" also suffered from the problem of low efficiency of solar energy conversion. To this end, the "Tianjin" uses the same solar cell panel as the "Shenzhou 12" manned spacecraft and the core compartment of "Tianhe", as well as "spatial arsenide 镓 solar cell technology", and the above technology can guarantee " "Tianjin" can still be used in electricity in cloudy days.

According to media reports, the second "Tianjin" has also been in the process of research and development.

When car manufacturers around the world are closer to the field of new energy, no one realizes what the future of new energy vehicles will be.

Although car companies have been actively trying, some people in the industry are not optimistic about the combination of "pure solar+car". Gim Sak, Honorary Professor, President of the Automobile Industry Society, President of the Automobile Industry Society, and Auto Industry Society in the United Kingdom.

Tesla CEO Musk also said that although he supports solar energy, the company has always avoided this technology because "the use of the most efficient field of solar is car."

More importantly, due to supply problems, the price of high -purity silicon used to manufacture battery boards by steel, aluminum, copper, and the cost of solar vehicles is difficult to reduce the cost of "Light Years 0" models of $ 263,000. This makes many people discourage.

Some people in the industry also said that if car companies cannot solve the problems of conversion efficiency, production costs, and design, they can achieve mass production with new energy vehicles with solar energy as the main driver energy. It may really wait for decades.

However, the International Energy Agency believes that as the price of oil is approaching the historical high, the price of solar energy is still cheaper, and solar cars are still competitive compared to traditional power cars.

In addition, with the continuous progress of technology, the price of solar panels has fallen, and every square inch solar panel can also provide more electricity. Sak emphasized that "despite many challenges, I think solar cars have huge potential."

Perhaps in the stage of solar technology, it is likely to use hybrid power to ensure that the car will not have energy shortage in the next decades in the next decades.

In the next decades, solar cars may shake the status of electric vehicles. However, if such cars want to "fly into the home of ordinary people", they still face two major challenges of cost and technology.
