The global landscape of energy storage has witnessed a rapid expansion, especially in the realm of lithium-ion battery storage technology. According to statistics from the Energy Storage Application Branch of the China Chemical and Physical Power Industry Association, the installed capacity of lithium-ion battery energy storage technology has grown exponentially since 2017, surging from 2.7 GW in 2017 to an impressive 19.9 GW in 2021, with a remarkable compound annual growth rate of 64.8%. As of 2021, China alone has achieved an accumulated installed capacity of 5.2 GW for lithium-ion battery energy storage technology. This trend is expected to continue with rapid growth in the coming years.
Of course, when discussing the energy storage market, it encompasses three main categories: commercial energy storage, home energy storage, and portable energy storage. While commercial and home energy storage boast larger scales, the portable energy storage market presents a unique niche. In this article, we'll delve into the patterns and dimensions of the portable energy storage market.
Portable energy storage, often referred to as "large-scale power banks" or "outdoor power sources," represents a flexible and convenient form of small-scale energy storage systems. These systems typically rely on built-in lithium-ion batteries to provide stable AC and DC power outputs, with battery capacities ranging from 100 to 3000Wh. In recent years, products with even higher capacities, such as 5000Wh and 9000Wh, have emerged. Portable energy storage solutions often feature a variety of interfaces, including AC, DC, Type-C, and USB, and some even come equipped with solar panels, forming small-scale power generation systems.
The primary application scenarios for portable energy storage are outdoor activities and emergency preparedness. In outdoor scenarios, these systems are used to charge personal electronic devices like smartphones and laptops, provide short-term power to appliances such as electric stoves, rice cookers, refrigerators, lighting fixtures, and heaters, as well as offer temporary power for emergency lighting, SOS signaling, outdoor operations, and more.
In emergency situations, portable energy storage systems serve as temporary power sources during natural disasters or power outages, ensuring basic household needs like lighting, cooking, and heating, and providing power to critical equipment such as medical devices and communication systems.
Furthermore, in recent years, portable energy storage has found applications in areas such as charging electric vehicles and powering recreational vehicles, demonstrating its versatility.
Both portable energy storage and home energy storage products began gaining traction around 2016.
According to statistics on shipment volumes provided by the China Chemical and Physical Power Industry Association, the portable energy storage market experienced an impressive compound annual growth rate of over 150% from 2016 to 2020, with shipment volumes reaching 4.84 million units in 2021, representing a 132% year-on-year increase. Due to factors like rising raw material costs and pandemic-related supply chain disruptions, the growth rate in the current year is expected to be around 70%. Industry experts estimate that the sales revenue of portable energy storage reached approximately 10 billion yuan last year.
In terms of demand, the United States accounted for the largest market share in 2021, at 50%, followed by Japan at 30%, and Europe at approximately 5%. However, Europe is experiencing rapid growth this year, and it is projected to account for 15% to 20% of the market demand due to a shortage of home energy storage products and higher prices in the European market, making high-capacity portable energy storage products a viable alternative. The Japanese market primarily focuses on emergency backup power, maintaining stable growth rates.
In conclusion, the portable energy storage market has undergone significant growth in recent years, with increasing demand driven by outdoor activities, emergency preparedness, and emerging applications. As the industry continues to evolve and innovate, larger capacity portable energy storage products are expected to further shape this dynamic market segment.
