Now in cities, people can easily enjoy the convenience brought by urban electric energy. But now more and more people are fond of outdoor sports and like to go outdoors to experience nature. Outdoor electricity consumption has always been a headache for everyone. With the advancement of science and technology, there are many ways to choose outdoor electricity. Today we will talk about outdoor electricity.
Diesel Generator—The Pioneer of Outdoor Electricity
Diesel generators, a representative of the early use of energy, are also the most important way of early outdoor power generation. This kind of equipment that relies on diesel to generate energy is also a step forward for people to use energy. At the beginning, it also received widespread attention. Diesel generators can achieve continuous energy generation and support the use of various scenarios. Then diesel generators have What are the pros and cons?
First of all, in terms of advantages, diesel engines have a high energy conversion rate, high thermal efficiency, and a wide range of applications. They can be driven only by diesel, and the threshold for use is low; moreover, diesel generators are more reliable, durable, and less faulty when working. , saving a lot of maintenance troubles; good fire performance, safer to use; simple operation, convenient daily maintenance, saving a lot of maintenance costs.
The disadvantage of diesel generators is that they are driven by diesel after all, so a lot of high-temperature exhaust gas and smoke will be generated during use, which has a negative impact on the environment; secondly, the noise of diesel generators is particularly loud; finally , When the diesel generator is used in a place with extremely low temperature, it will be difficult to start, which is inconvenient to use.
However, diesel generators were also a good choice in the early outdoor electricity consumption, which can be separated from the urban electricity environment, but this is not a good solution for outdoor electricity consumption.
There is also a silent generator that can eliminate noise. This kind of generator needs bulk diesel or gasoline to make the generator work normally, but it is a pity that due to various conditions, it is not easy to buy bulk gasoline in China. to.
Lead-acid battery—a representative of the conversion from power generation to power storage
Next, I will introduce another energy product, lead-acid battery. That is what we commonly call batteries, which can often be seen in daily life and are used in a wide range of conditions. Lead-acid batteries can be seen in industry, agriculture, or on various vehicles, so that's it What are the advantages and disadvantages of lead-acid batteries that are often seen in daily life?
The advantages of lead-acid batteries: First, the raw material capacity is obtained, and the price is relatively low, so it is affordable to use; second, even high-rate discharge performance can be well exerted; third, the probability of being affected by temperature is low and can be used in It works in the environment of -40~+60℃; fourth, it is suitable for floating charging, has a longer service life and has no memory effect; finally, the waste lead-acid battery is easy to recycle, has less impact on the environment, and is conducive to protecting the environment.
Everything has two sides. Now that we have finished talking about the advantages, let’s take a look at the disadvantages of lead-acid batteries: first, the battery energy ratio is low, generally 30~40Wh/kg; second, there is still a certain gap between the service life and Cd/Ni batteries ; Third, the manufacturing process is easy to pollute the environment, must be equipped with three waste treatment equipment, there must be a full range of treatment measures.
Photovoltaic power generation - a major advancement in energy utilization
Nowadays, energy conservation and environmental protection are increasingly advocated. With the continuous development of the energy industry, photovoltaic power generation of solar cells has appeared before people's eyes, and due to the characteristics of photovoltaic power generation, it has developed rapidly, and more and more energy products use What are the advantages and disadvantages of the photovoltaic power generation of this solar panel?
Let me talk about the advantages of photovoltaic power generation first: first, there is no risk of depletion, relying on sunlight to obtain energy; Clean; third, it is not limited by the geographical distribution of resources, as long as it is sunny and sunny, it can be charged at any time, and can take advantage of the advantages of building roofs, such as areas without electricity, and areas with complex terrain; fourth, there is no need to consume fuel and erect power transmission The line can generate electricity and supply power on the spot, and the conditions of use and threshold are low; finally, the construction period of solar panels is short, and the time spent on obtaining energy is short. And it is also very convenient to use solar panels to charge now. The conditions of use are only enough to require sunlight, which is currently the way to obtain energy with the lowest restrictions.
After talking about the advantages, let's take a look at the disadvantages of photovoltaic power generation: first, the energy density is low, the dispersion is large, and it is too much restricted by external conditions. Even if there is enough sunlight, the energy density projected on the panel is too low; second , due to the low energy density of solar energy, if you want to use solar panels to achieve the ideal charging power, the photovoltaic power generation system will occupy a large area; third, the conversion efficiency is low, and the conversion efficiency of photovoltaic power generation refers to the light energy The ratio of conversion to electrical energy is restricted by various factors, and the current conversion rate cannot achieve an ideal state; fourth, solar panels need direct sunlight to convert energy into electrical energy, so they can only generate electricity during the day , it cannot be carried out at night, and if it is cloudy and rainy, the battery panels cannot be used, which is directly affected by the weather conditions; finally, the cost of solar panels is high, and the manufacturing process of crystalline silicon cells, the components of the panels, is highly polluting and high-energy consumption.
Inverter—the simplest and most direct way to use electricity outdoors
Now there are many ways to play outdoors, but the most chosen one is the self-driving tour, because it is very relaxing to be unrestrained, and the problem of electricity consumption is naturally associated with the car. Since the battery on the car is used to solve the problem of electricity consumption Will choose to use the inverter. The advantage is naturally convenience, a bit of local materials, directly using self-driving vehicles to achieve the purpose of outdoor electricity. However, it is not suitable for long-term use, due to various factors of the battery, the conversion efficiency of the inverter is low and the cost is high, and the inverter cannot be separated from the car, and there is a possibility that the power of the car battery will be used up, resulting in failure to start the car. Fire starts.
Connecting the car battery to the inverter outdoors is not a stable and long-lasting method for outdoor power consumption. Long-term use will accelerate the aging of the battery and reduce the service life of the battery. In addition, the battery may be damaged during the use of the inverter. Even causing danger to users, obviously this is not a better solution for outdoor electricity use.
portable power station—a mature masterpiece of outdoor power consumption
The last is the portable power station, which is also one of the most common outdoor power storage devices. Since it is impossible to enjoy the convenience of electric energy outdoors like in the city, the portable power station has highlighted its role, so let's take a look at the advantages and disadvantages of the portable power station.
Advantages of outdoor power supply: In terms of portability, most of the portable power stations suitable for outdoor use can be used for portable travel, with a built-in handle, so you can pick it up and go; secondly, it has rich interfaces, such as AC output, USB output, and car charger interface output , which is convenient for users to use in different scenarios, with more options, and more convenient to use; finally, the large battery capacity can provide power support for multiple electric devices, and there is no need to worry about long-term battery life.
