Under the sunlight, the super photovoltaic film quickly charges the battery pack. This charging speed shocked everyone.
The charging speed of just one square meter of photovoltaic panels is faster than the ordinary 220V voltage charging speed. This is simply incredible.
"Boss, according to the current charging speed, under the current sunshine conditions, it only takes five hours to fully charge the battery pack..."
Based on the current charging speed, the technician gave an answer. This answer made Zhang Fan take a breath.
This charging speed is too fast. According to the current charging speed, electric vehicles basically do not need to be charged at charging piles.
Because when the sun shines during the day, the sun can charge the car. The utilization rate of this kind of solar energy is too exaggerated.
If this thing is used on a large scale, it will greatly save human energy. This type of energy is inexhaustible, has no pollution, and has almost no cost except photovoltaic films.
Look at this photovoltaic film. It is like a thin film and has very good ductility. This property determines that this thing can basically be laid anywhere.
Super photovoltaic films and super batteries are a perfect match. Super batteries store relatively large amounts of electricity, and photovoltaic films can continuously charge and store energy for super batteries when the sun is shining.
The combination of the two can completely subvert the current human energy structure and reduce the cost of human energy use. Even ordinary people can realize how big the profit is.
"How much does it cost?"
Zhang Fan couldn't help but ask.
"The production cost of our laboratory is about 100,000 yuan per square meter. If mass production is carried out on a large scale, the price should be significantly reduced..."
The technician said seriously that the cost of making it in the laboratory just now was about 100,000 yuan. But even this is still very cost-effective. The life of this thing is very long, and it will last forty or fifty years without any problems.
"Go and refit a Yugong."
Zhang Fan said directly, Tesla Yugong, Tesla's latest electric heavy truck. This heavy truck has a load capacity of 70 tons and uses an all-solid-state battery pack. It has a cruising range of 600 kilometers when fully loaded.
Don't underestimate the 600 kilometers, this is a heavy-duty truck with a load capacity of 70 tons. This thing is not a small car. It only pulls a few people and has a full load of 70 tons. It is not allowed to go on the elevated city highways.
This is a heavy-duty logistics vehicle with a huge cargo compartment at the back that can load a lot of things.
Under Zhang Fan's instructions, the technicians began to get busy. They began to modify a brand-new Yugong. The modification method was very simple, that is, covering the front, compartment and other places with super photovoltaic film.
It took three days to completely modify the entire car. The modified car looks very cool. The black photovoltaic film covers the front and the cabin, making the whole car look like a Darth Vader.
The entire car seems to be covered with a layer of black glass. The appearance is cool, but that is not important. What is important is to test the performance of this car.
"Fully loaded, experiment. Departing from Lanhai City, destination Mohe. No rest at all times except during night when highways are closed..."
Zhang Fan's words made the staff nod. They immediately began to prepare for this experiment. The purpose of this experiment was very simple, that is, to see the effect of the super photovoltaic film.
The total length of the highway from Lanhai City to Mohe is 4,800 kilometers. According to Yu Ping's current performance, the power consumption when fully loaded is about 100 kilowatt hours per 100 kilometers.
According to the current electricity price in China, it is about 1 yuan per kilometer. This is already enough savings. If you switch to fuel, with such a load capacity, you will need at least 30L of oil per 100 kilometers. Even if it costs 5 yuan per liter, it will cost 150
Yuan.
For trucks, they often travel long distances and may need to transport goods for thousands of kilometers at a time. In this case, even if you save a dime per kilometer, you will save a lot of fuel.
But this time, Zhang Fan and the others are going to play hard. This Yugong has a super photovoltaic film covering an area of up to 10 square meters.
If based on laboratory prices, the price of this set of photovoltaic films alone is as high as 1 million. Not only that, the car's battery pack has also been doubled, with a comprehensive cruising range of up to 1,200 kilometers.
"Set off……"
Early the next morning, the truck set off. The battery was fully charged when it set off. The battery pack was charged 1,200 kilowatt-hours at a time, which cost a total of 1,200 yuan based on current electricity prices.
Two specially hired drivers drove the car into the underground expressway, and then directly onto the highway. Once on the highway, the driver directly put the car into driverless mode, and the speed was directly increased to a maximum of 100 kilometers per hour.
The car enters driverless mode and starts traveling rapidly at an average speed of 100 kilometers per hour. In driverless mode, the driver is actually very relaxed.
Tesla's driverless driving is now very good. Even on the highway, the driver can rest at will.
The car was moving quickly, but the driver soon discovered a special situation. That was that the battery was not fully charged.
After running for several hours, the battery was still 100%.
The on-board researchers in the car laughed when they saw this amount of electricity. A photovoltaic film with such an area can actually replenish the electricity consumed by a full load.
The car is traveling fast, and the driverless function allows the car to maintain a high speed. The front of Yugong's car is very large, and the space is also very large. The huge front of the car is completely like a small RV.
The driver can lie comfortably in the back to sleep, entertain, and cook and eat in the car.
The car did not enter the waiter for a whole day. It kept running on the road, and when the sun went down, the battery's power reserve was still 100%.
This situation made the two drivers completely confused. The technicians who followed were very excited. The car continued to drive at night. For the unmanned driving system, it was the same during the day and at night.
However, for safety reasons, the two drivers took turns sitting in the driving position and watching. After running all night, at dawn, only 10% of the battery was left.
The battery has already alarmed. If I don't charge it, if I consider it 10%, I can run a maximum of 100 kilometers.
But a miracle happened. After dawn, the battery began to charge slowly. When the sun rose, the charging speed accelerated. At three o'clock in the afternoon, the battery was fully charged again.
Look at the mileage this time, it has exceeded 3,000 kilometers. In other words, these 3,000 kilometers did not cost a penny for electricity, saving 3,000 yuan for free, and saving 3,000 yuan in freight costs, like this
The level of savings is exaggerated.
The results were sent back to Tesla headquarters. Zhang Fan and all the technical staff cheered. Powerful, powerful conversion rate. Such a powerful conversion rate can completely change many things in the world. This huge market is very scary.
