Portable energy storage devices refer to small energy storage devices with built-in lithium-ion batteries, which can be divided into portable energy storage devices with a capacity of less than 500Wh, 500-1,000Wh, and more than 1,000wh according to the amount of electricity charged. With a 200W portable energy storage device.
Market status: From 2017 to 2021, the global portable energy storage power supply shipments and market size have increased year by year. Although the industry started late and has a short development time, it has a wide range of applications and rapid development. It is estimated that the market size of the portable energy storage power supply industry in the future It will continue to grow, reaching 88.23 billion yuan in 2026; in 2020, 91.9% of the world’s portable energy storage power supplies are produced in China, and 47.3% of all portable energy storage power supplies are sold to the United States; in 2018, the development of China’s lithium battery industry will drive portable energy storage. Energy storage power supply shipments and market size have begun to grow explosively and are expected to continue to grow in the future.
Driving factors: Portable energy storage power sources mostly use lithium batteries as cells, so the progress of lithium battery capacity and output power technology directly drives the improvement of portable energy storage power supply capacity; with the upgrade of lithium battery performance and cost reduction, portable energy storage power sources The potential market for energy storage power is further expanded. Outdoor activities are the application areas with the largest proportion of portable energy storage power sources, accounting for 43.6%. Under the influence of the epidemic, travel methods such as indoor gathering entertainment and group tours have decreased. Outdoor activities such as camping have become popular, directly driving the development of the portable energy storage power market. In the global portable energy storage power application field, the emergency field accounts for 41.5%. In the 20 years from 2000 to 2019, the number of major natural disasters in the world increased, and the number of victims and the scale of economic losses increased. An important means of emergency use of electricity.
·Development trend: With the increase in energy density and cost reduction of lithium batteries, the proportion of high-capacity portable energy storage power sources will continue to increase; the unit price of high-capacity portable energy storage power sources will fluctuate, which will lead to an increase in the average selling price and further expansion of the market scale . Among the global household electricity prices, developed countries such as Europe and the United States have higher electricity costs, and overseas household energy storage demand is larger; the attributes of household energy storage and portable energy storage power sources are relatively similar. The transformation of high-power portable energy storage power sources into household energy storage has a small span.
