Batteries are a great invention, especially the "lithium batteries" we use today. Regardless of whether there will be more advanced batteries in the future, at least the current "lithium batteries" will make our lives more colorful. Mobile phones, cameras, laptops, hand-held electric tools, even cars, airplanes, etc. are inseparable from "lithium batteries"
The portable battery power station, car emergency starting power supply, mobile power supply, uninterruptible power supply, and emergency power supply mentioned in this article are the five representative works of the application of "battery" technology. Because these five products have the same features of "battery" power storage and power supply, and because of different application directions, resulting in different technical emphasis, they should not be confused.
1. Portable battery power station
This is a product that has only appeared in recent years. I first came into contact with this product in 2014. To be honest, this is a product of the nature of "one-size-fits-all". Many people call it a large power bank, a large mobile power supply, an outdoor emergency power supply, and an outdoor uninterruptible power supply.
In 2013, there was a leak at the Fukushima nuclear power plant in Japan. In addition, there were many earthquakes and typhoons in Japan, and there were frequent power outages, which affected the life and work of local residents. Portable is developed to solve the power shortage. This work can be independently powered from the grid, and can efficiently use solar power to generate electricity. Lithium batteries store electricity in large capacity, and then convert it into various AC and DC power to supply people with electricity for daily appliances, such as lighting, cooking Meals, boiling water, tea, computers, printers, telephone communications, etc.; because it is light, it can be easily carried at home and in the office to ensure normal life and work.
The concept of the work at that time was Power Station (power station), which has power generation, power storage, power transformation, power supply, monitoring, software and hardware protection, frequency modulation (because Japan has 50HZ, 60HZ), fault self-checking, fault recovery, several major functions in one , a work developed after miniaturizing the concept of household energy storage photovoltaic energy storage power station.
The biggest feature of "portable" is that it can get rid of the limitation of "wires" and supply power to various electrical appliances for a long time, AC and DC, and it is light and portable.
2, ups uninterruptible power supply
This kind of power supply appeared relatively early, and it was the earliest product among the five power supplies. It appeared with the rise of computers. The ups power supply used lead-acid batteries at that time, and now there are lithium battery products. The purpose of this product is to ensure that the computer can still supply power to the computer for a certain period of time in the event of a sudden power failure. During this period of time, the data can be saved normally. Generally, the power supply time is about 20 minutes, and the battery capacity is small. But do not pursue lightness and portability; the computer usually uses the power grid, and the UPS power supply starts when the power grid fails. The startup time is very short, milliseconds (ms), and the computer switches from the power grid to the UPS uninterruptible power supply, and the computer will not shut down. Yes, data will not be lost.
3. EPS emergency power supply
EPS emergency power supply is also used to continue powering key equipment when the power grid suddenly fails. Most of them use lead-acid batteries, and now lithium batteries are also available. This kind of product is generally equipped in important places and buildings, and is usually a backup power supply for fire-fighting facilities; although generators are often used as backup power for buildings, it takes time to start the generator. The biggest advantage of using EPS emergency power supply is , the device will not shut down when the backup power is enabled. The start-up time of the EPS emergency power supply is also in milliseconds (ms), the power is generally large, and the battery capacity is also large, at least to ensure that the key equipment of the building can be used for more than 40 minutes.
4. Automobile emergency start power supply
The car emergency starter power supply, as the name suggests, is used to start and ignite the car. When the car's starter battery loses power, the car will not ignite and the engine will not start. It is precisely because of the anxiety of the battery loss that the emergency starter power supply of the car caught fire.
This kind of power supply used lead-acid batteries in the early days, but now most of them use high-rate lithium batteries. At the same time, they also integrate the functions of mobile power and charging treasures, and the battery capacity is not much. Lightweight, portable, car owners with a strong sense of urgency are more willing to buy, are you prepared?
5, mobile power
Mobile power is popular with the rise of touch-screen mobile phones. Large-screen mobile phones are getting thinner and thinner, and the battery cannot be disassembled. Therefore, mobile power is popular, and mobile phone users will buy mobile power. Mobile power supply is mainly a backup power supply for mobile phones, tablet computers and other handheld devices with small power consumption. It is mainly light and thin, and the battery capacity is not large. Speed up, now a power bank is no longer a must-have for your phone.
Summary: With the development of science and technology, various technical products have enriched our lives, and at the same time created various needs. Computers have created UPS power supplies, large-screen mobile phones have created mobile power supplies, automobiles have created emergency starter power supplies for cars, and building fire protection has created EPS emergency power supplies. What about portable?
