Portable energy storage solution

Portable energy storage, also known as "outdoor power supply", is a small energy storage system composed of a control board, battery pack, inverter, and BMS system that can provide stable AC and DC power output. It functions similarly to a "large outdoor power bank". The following is a detailed introduction to portable energy storage:

1. Working principle

The portable energy storage power supply consists of a set of AC+DC charging+AC and DC inverters. When the public power supply is supplying power normally, the battery in the portable outdoor energy storage is in a charging state. Once the main power supply is interrupted, the battery immediately outputs the stored DC power to the inverter and converts it to AC power for device charging. The duration of battery power supply will be determined based on the power of the electrical equipment used.

 2. Main features

1) **Highly integrated * *:Portable energy storage power sources highly integrate decentralized charging devices, energy storage devices, and power supply devices, making it convenient for users to use.

2)  * * Convenience * *: Portable energy storage power sources are small in size and light in weight, making them easy to load, unload, and transport. They can be easily carried to where they are needed without the need for disassembly, wiring, or installation.

3)  **Diversity of Energy Storage Functions **: Portable energy storage power sources can store electricity generated by solar energy, the city grid, cars, generators, and wind power.

4)  * * Diversity of power supply functions * *: Portable energy storage power sources can release the stored electrical energy from batteries, mainly providing high-power AC power for household appliances such as refrigerators, air conditioners, etc; It can also assist in providing direct current for electronic products such as mobile phones, cameras, etc.

Meanwhile, portable energy storage power sources also have features such as safe power output and corrected sine wave output.

 3.  Main specifications and application scenarios

Portable energy storage products can function in various scenarios:

1)  **Outdoor field**: In outdoor activities, portable energy storage products can charge personal digital products such as mobile phones and computers, as well as provide short-term power supply for appliances such as ovens, rice cookers, refrigerators, heaters, lighting fixtures, etc; It can also be used to ignite and start vehicles, provide emergency lighting, and provide temporary power for SOS distress. The capacity demand for portable energy storage products in this field is relatively low, generally limited to 1 kWh, with a preference for consumer level demand below 1 kWh.

2) * * Emergency field * *: In the event of natural disasters or other emergencies, portable energy storage products can be used as emergency power sources to supply power to households.

The demand for portable energy storage products in this field is relatively high, with a rigid demand for backup electricity above 1 kWh.

3) * * Other fields * *: Portable energy storage products can also be used to charge vehicles or provide power to areas with power shortages.

However, there are relatively few applications in this area.

 4.  Market situation

1)  * * Global Market * *: Currently, the global portable energy storage market is developing rapidly.

 Among them, the United States is the world's largest market for portable energy storage applications, mainly benefiting from the high outdoor travel rate and the demand for outdoor electricity; Japan is the second largest market, mainly due to frequent natural disasters such as earthquakes and tsunamis, which have a high demand for emergency power equipment. In addition, due to the outbreak of the Russia-Ukraine conflict, the stability of energy in Europe has been in turmoil. Some families will use rooftop photovoltaic+household energy storage to ensure power consumption. Portable energy storage products are also favored.

2)  * * Chinese market * *: In China, due to relatively low per capita consumption capacity and benefiting from a stable power supply system, the portable energy storage product market is still in its infancy. But with the development of China's economy and the gradual improvement of per capita consumption capacity, coupled with the rapid recovery of the tourism market after the opening up of the epidemic, the number of camping and self driving tourists is increasing, and the market potential for portable energy storage in China is huge. At the same time, China's consumer electronics manufacturing industry has complete upstream and downstream supporting facilities, complete infrastructure, and comprehensive advantages in cost and technology in the field of portable energy storage.

5. Development Trends

1)  * * Large Capacity Quantity * *: As the cost of battery cells gradually decreases, the trend of portable energy storage developing towards large capacity will become increasingly clear.

 Large capacity products are mainly aimed at home backup power users with frequent power outages, professional level users, and outdoor users with high requirements for electrical appliances.

2)  * * Technological Upgrade * *: In the future, portable energy storage products will continue to undergo technological upgrades to improve energy density, output power, and safety indicators to meet the needs of more application scenarios.

3)  * * Application scenario expansion * *: With the decrease in price and improvement in performance of portable energy storage products, their application scenarios will be further expanded. In addition to outdoor leisure and emergency preparedness, portable energy storage products will gradually penetrate into more fields such as home energy storage and vehicle charging.
