1. Portable energy storage: It is suitable for outdoor traveling and emergency disaster preparedness. In earthquake and tsunami prone areas, it can be combined with solar panels to form a small-scale power generation system to meet the electricity needs of disaster victims.
In addition to the outdoor leisure and entertainment market, due to its lightweight and other characteristics, one of the important uses for emergency disaster relief: the use of emergency disaster preparedness market size is expected to be 2.02 million units in 2021, the main market for Japan, Japan is expected to ship 1.26 million units in 21 years, accounting for 63% of the emergency disaster relief market shipments. In addition, in the Japanese market, emergency disaster relief demand shipments account for 87% of its total portable energy storage market in ’21.
2. Caravan energy storage: lead-acid battery energy storage system is relatively mature, and has been used in a large number of finished caravans.
Mainly divided into lead-acid batteries (lead) and lithium batteries, lead-acid batteries share of 97%; lithium batteries in the rapid development (technology maturity and cost reduction).
3. home energy storage, expensive electricity + grid stability needs to be improved.
According to QY Research, the global portable generator market size of about 18.7 billion in 2020, up to 30.4 billion in 2026, cagr 7.2%. Advantages of home energy storage: stable electricity consumption + low cost, with policy subsidies.
Home energy storage is currently the main development market for Europe, the basis of home energy storage system is mainly electrochemical energy storage, according to CNESA 2018 cumulative data, electrochemical energy storage user side dominates, accounting for 32.6%. Electrochemical energy storage will be further divided into lithium-ion batteries and lead-acid batteries, with lithium-ion batteries dominating.
