The difference between portable energy storage power supply and other power supplies with batteries（

Portable energy storage power supply, automobile emergency starting power supply, charging bank, uninterruptible power supply and emergency power supply are the five representative works of "battery" technology application. Because these five products all use "batteries" to store electricity and supply power in the same way, but also because the application direction is different, leading to different technical emphasis.

1、 Portable power station

Portable energy storage power supply is a high-tech product that has emerged in recent years. It is fashionable and novel. Many people call it a large power pack, a large mobile power supply, an outdoor emergency power supply, and an outdoor uninterruptible power supply.
In 2013, the Fukushima nuclear power plant in Japan leaked, and there were many earthquakes and typhoons in Japan, which often led to power outages, affecting the lives and work of local residents. The portable energy storage power supply is developed to solve the problem of power shortage. This work can be independently powered off the grid, and can efficiently use solar energy for power generation. The lithium battery can store power in large capacity, and then convert it into various AC and DC power supplies for people's daily electrical appliances, such as lighting, cooking, boiling water, tea, computers, printers, telephone communications, etc. Because of its portability, it can be easily carried in the home and office, Ensure normal life and work.

The idea of the work at that time was Power Station, which was a product developed after miniaturization of the concept of household energy storage photovoltaic energy storage power station, with power generation, power storage, transformation, power supply, monitoring, software and hardware protection, frequency modulation, fault self inspection, fault recovery and several functions.

The biggest feature of "portable energy storage power supply" is that it can get rid of the restriction of "wires" and supply power to various electrical appliances for a long time, AC and DC, and it is light and portable.

2、 UPS
This kind of power supply appeared earlier, which is the earliest product among the five kinds of power supply, and 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 period of time in the event of sudden power failure. During this period of time, the data can be saved normally. Generally, the power on time is about 20 minutes. The battery capacity is very small, but it does not pursue lightweight and portable; The computer usually uses the power grid. When the power grid is cut off, the UPS power supply starts. The starting time is very short, in milliseconds. When the computer switches from the power grid to the UPS uninterruptible power supply, the computer will not be shut down to ensure that data will not be lost.

3、 EPS emergency power supply

EPS emergency power supply is also used to supply power to key equipment when the power grid is suddenly cut off. Most of them use lead acid batteries, and now there are lithium batteries. This product is generally equipped in buildings in important places, and is generally the backup power supply for fire fighting facilities; Although the generator is often used as the backup power supply for buildings, it takes time for the generator to start. The biggest advantage of using EPS emergency power supply is that the equipment will not be shut down when the backup power supply is enabled. The starting time of EPS emergency power supply is also millisecond (ms). The power is generally large, and the battery capacity is also large. At least the service time of key equipment of the building should be more than 40 minutes.
