The technical barriers in portable energy storage are evident in:
Product Development: The development of portable energy storage products requires a comprehensive approach to industrial design, thermal management, power management, and lithium battery modules. It necessitates deep integration with application scenarios to achieve various charging and output methods, effectively improving charging and discharging efficiency. These products must also provide multiple protections against overcharge, over-discharge, overload, short circuit, and other potential issues, presenting certain technical challenges.
Product Iteration: As intelligent terminals continue to evolve and outdoor power consumption scenarios diversify, consumer demands for portable energy storage products will increase. This includes a growing need for high-power, lightweight, multi-functional, and intelligent devices. The advancing industry technology has raised the entry barrier for the portable energy storage industry.
Fine Quality Control: Due to the wide range of appliances that portable energy storage products need to adapt to, the numerous integrated parts, and higher safety requirements, meticulous quality control throughout the entire production process is essential. For example, portable energy storage products from Huabao New Energy must meet six safety protection standards and undergo nine quality inspection procedures. The refined quality control system in the production process of portable energy storage products has also created a barrier for new market entrants.
Portable energy storage is primarily composed of batteries, energy storage converters, circuit boards, electronic components, and casings. China boasts a developed consumer electronics manufacturing industry with a complete industry chain, excellent infrastructure, and labor cost advantages, making it a major global source for portable energy storage.
Main Market Threats for Portable Storage Stations
Technology Aspects: The surge in orders may deplete potential market growth. Before significant product iterations occur, existing users may lack the incentive to repurchase. Parameter competition can lead to price wars as manufacturers vie for market share. This competition can diminish brand loyalty among consumers, especially when ordinary portable energy storage is considerably more expensive.
- Convergence and Homogenization
Both products heavily rely on e-commerce platforms for distribution and employ similar marketing methods. The most serious issue is the similarity in the products themselves, with only minor changes in color and material, indicating a high degree of overlap in the list of upstream component suppliers. This can lead to a price war due to the lack of differentiation.
- Economic Aspects
Portable energy storage devices are not fast-moving consumer goods (FMCGs). They have high unit prices and long decision-making cycles. Additionally, the weight of these devices can be substantial, with 1 kWh devices generally weighing over 10 kg and 2 kWh devices reaching 20-30 kg. Even with advancements in solid-state batteries, the weight of a 2 kWh energy storage device is around 15 kg.
- Social Aspects
There is an influx of supply from various low-cost enterprises, which can fragment the market. Many companies have invested significant sunk costs in the early stages of their projects, making it difficult for them to recover and adapt to market changes. The market also exhibits high concentration, with the top five brands accounting for nearly 60% of the global market share.
- Other Aspects
The Russia-Ukraine conflict has impacted energy prices. The EU has taken measures to restore energy prices to pre-conflict levels by the end of 2022. Companies must not mistake the abnormal market conditions caused by the conflict for the industry norm and should avoid overexpansion based on these temporary conditions. The normalization of electricity prices may lead to inventory backlogs as products manufactured during the conflict period may not meet current market demands.
