Chapter 674 Electricity Storage Capability
Pollution, and energy, this is an eternal topic.

The only feasible way to solve this problem is to step up the development of new energy sources.

Solar energy is the leader among these newly developed energy sources.

Solar energy has been used for heating, such as solar water heaters and so on.

Those are just the lowest-tier apps, though.

There are fewer high-level applications.

For example in the automotive field.

Solar electric vehicles replace oil with photoelectricity, which can save limited oil resources.During the day, the solar cell converts light energy into electrical energy and automatically stores it in the power battery.

No pollution, no noise.

Because no fuel is used, solar electric vehicles will not emit harmful gases that pollute the atmosphere.

Without an internal combustion engine, the solar electric vehicle cannot hear the roar of the internal combustion engine of a fuel vehicle when driving.

Comparative advantage over gasoline vehicles.

Practical solar-powered vehicles have many advantages compared with fuel vehicles, except that their driving speed is much lower than that of fuel vehicles.

Solar electric vehicles consume less energy, and only 3-4 square meters of solar cell components can be used to drive solar electric vehicles.

In the process of energy conversion, fuel vehicles must follow the law of the Carnot cycle to do work, and the thermal efficiency is relatively low. Only about 1/3 of the energy is consumed in driving the vehicle forward, and the remaining 2/3 of the energy is lost in the engine and drive chain. ; while the heat conversion of solar electric vehicles is not limited by the law of the Carnot cycle, 90% of the energy is used to drive the vehicle forward.

Another solar car is also easy to drive.

No need for electronic ignition, just step on the accelerator pedal to start, and use the controller to change the speed of the vehicle.

There is no need to shift gears or step on the clutch, which simplifies the complexity of driving and avoids potential accidents caused by operational errors. It is especially suitable for driving by women and the elderly.

In addition, the solar-powered vehicle adopts an innovative front axle and steering system, independent front and rear suspension, and four-wheel drum brakes, from 30 kilometers per hour to sudden braking, and the brake line does not exceed 7.3 meters.

Due to the simple structure of the solar electric vehicle, except for the regular replacement of the battery, it basically does not require daily maintenance, which saves the troubles of regular maintenance such as frequent oil replacement and cooling water addition for traditional vehicles.

The compact body and flexible steering make it easy to park the car in crowded urban parking lots.

When driving in the city, in order to wait for the traffic lights, you must stop and start continuously, which not only causes a lot of energy waste, but also increases air pollution. Using solar electric vehicles, when decelerating and parking, the motor can be prevented from idling, which greatly improves energy use. Efficiency and reduced air pollution.

Thirdly, solar electric vehicles have no components such as internal combustion engine, clutch, gearbox, drive shaft, radiator, exhaust pipe, etc., so the structure is simple and the manufacturing difficulty is reduced.

It can be said that once a breakthrough in technology is made for solar-powered cars, they will definitely become popular all over the world.

After all, comparatively speaking, solar energy is considered an inexhaustible source of energy for the time being.

Also, the vast majority of solar energy is wasted.

At this stage, the earth is warming and the glaciers at the poles are melting.

If the solar energy irradiated on the earth can be absorbed, stored and utilized, it will still be very helpful to alleviate global warming.

Converting sunlight into electrical energy is an important way to utilize solar energy.

People made the first photocells as early as the 50s.

Install the photovoltaic cell on the car, and use it to continuously convert sunlight into electrical energy to start the car.

This car is exactly the solar car that rises up.

There are dense honeycomb-like devices on the solar car, which are solar panels.

The iron wings on the artificial satellites that we usually see are also a kind of solar panels that power the satellites.

According to the different semiconductor materials used, solar cells are usually divided into silicon cells, cadmium sulfide cells, gallium arsenide cells, etc., among which silicon solar cells are the most commonly used.

There are several types of solar cells, such as circular, semicircular and rectangular.On the battery are small sheets of silicon that are as thin as paper.

Evenly doping some boron on one side of the silicon wafer, doping some phosphorus on the other side, and installing electrodes on both sides of the silicon wafer, it can convert light energy into electrical energy.

Typically, silicon solar cells can convert 10% to 15% of solar energy into electricity.

It is easy to use, durable, clean, and does not pollute the environment. It is an ideal power supply.It's just that the ratio of photoelectric conversion is smaller.

Install the photovoltaic cell on the car, and use it to continuously convert sunlight into electric energy as the power to drive the car. This kind of car is a newly emerging solar car.

The general method of using solar energy for solar cars.In sunlight, solar photovoltaic panels harvest sunlight and generate electricity that is commonly used by people.

This energy is stored by the battery and provides power for future travel.

Or it can be directly supplied to the engine to store electricity while driving.

The energy drives the wheels to move through the engine controller, pushing the solar car forward.

So far, the application technology of solar energy in automobiles mainly has two aspects-

Either as a driving force, or as an energy source for ancillary equipment in the car.

As for Qin Feng's solar car, it completely uses solar energy as its energy source.

The most critical data affecting solar cars is the photoelectric conversion rate.

Now, the most mature and advanced technology is from Sam Country, and the photoelectric conversion rate can reach 34%.

Of course, this is only on the surface.

At least, in Qin Feng's place, this statistic is not the highest.

At least, the photoelectric conversion rate of Qin Feng's solar car has reached an astonishing 90%.

Of course, this is still because there are no suitable materials on the earth.

Otherwise, the photoelectric conversion rate will only be higher.

Of course, these words cannot be spoken.

Next, another factor that affects the development of solar vehicles is the storage capacity of batteries.

Even if a solar car has a high photoelectric conversion rate, it will be embarrassing if it cannot store electricity.

Can drive normally during the day.

However, at night it becomes embarrassing.

Even, in the tunnel, when the sun is not visible, the car will stop because there is not enough energy.

That would be embarrassing.

What's more, no one can guarantee that every day will be sunny.

If it is cloudy or rainy, or when the solar energy is relatively weak, a solar car with a relatively weak power storage capacity is simply a loser.
Therefore, from the very beginning, Qin Feng put the power storage capacity of the solar car first.

Similarly, the electric shock capability of new energy vehicles is also very powerful.

It can run [-] kilometers on a single charge.

Of course, that's just a low-end product for sale.

Like Qin Feng's car, the power storage capacity is terrifying.
