In terms of mobile energy storage, portable energy storage is developing particularly fast, and home energy storage (for emergency use) is also about to develop vigorously.

Mobile energy storage can be divided into three categories in terms of consumption scenarios:

General energy storage or portable energy storage, there are a number of uses: First, in outdoor travel, can give cell phones, computers and other equipment power supply, so that you can meet the demand for a variety of portable outdoor travel; Second, in emergency preparedness for these situations, such as earthquakes, tsunamis often occur in the place, can be composed of small power generation system and solar panels to meet the needs of the victims of the power supply. According to the China Chemical and Physical Power Industry Association, the market is expected to reach RMB 88.2 billion by 2026.

Caravan energy storage, lead-acid battery storage system has been more mature, finished caravans are used in large quantities is it. In the past few years, there is a trend that RVs will be equipped with additional folding solar panels for backup power generation. According to Everest, the market for RV batteries is expected to reach $437 million by 2026. As energy storage systems continue to iterate and upgrade, there will be a lot of opportunities for RV energy storage.

For home energy storage, overseas electricity prices are high and grid stability needs to be improved. Zhongyan Industrial Research Institute said in a news release that the global household energy storage scale is about $7.5 billion in 2020, and is expected to reach $26.4 billion by 2027, with a compound annual growth rate of 20%.

Japan’s emergency disaster relief market should not be underestimated in the portable energy storage market.

Portable energy storage shipments are growing rapidly around the world. According to the China Chemical and Physical Power Association, it is expected to grow at a compound annual growth rate (CAGR) of 57% from 20-26. There are three categories when broken down by different demand uses: 1) For outdoor activities, which is expected to account for 44% by 26. ①Outdoor leisure market, it is estimated that it can account for 80% of the outdoor activities market, like long-distance self-driving, mountain and wild camping bases, cross-country adventure, photography and fishing and so on are all counted, and now the main market is Europe and the United States. With the rapid increase of outdoor people in China, the Chinese market has great potential for development. ② outdoor work market, is expected to account for 20% of the outdoor activities market, outdoor aerial work in this scope. 2) emergency preparedness, is expected to account for 37% of the 26 years, flood rescue, mobile medical epidemic prevention, etc. are in this category, the main market is Japan. 3) other markets, is expected to account for 19% of the 26 years, such as vehicle charging, DIY, power shortages in areas with electricity, etc. all belong to this category.

Portable energy storage has a very important use for emergency disaster relief, this is because it is relatively lightweight, in addition to the outdoor recreation and entertainment market is the only important use. 2021 emergency disaster preparedness market is expected to be 2.02 million units for this purpose, Japan is the main market, is expected to ship 1.26 million units in Japan in 2021, accounting for 63% of the shipments of the emergency disaster relief market. In addition, in the Japanese market, shipments for emergency disaster relief needs will account for 87% of the total portable energy storage market in 2021.

Caravan energy storage market, caravan shipments are mainly in Europe and the United States, but also in our domestic rapid development.

RV energy storage mainly lead-acid batteries (dominant) and lithium batteries. The share of lead-acid batteries can reach 97%, lithium batteries are developing rapidly, the technology is getting more and more mature, and the cost is also decreasing. Battery life will have an impact, so the replacement and retrofit in the caravan energy storage market is the main part of the market in 2020, this part of the market share is about 76.8%. Lithium batteries are now mainly used in the aftermarket. Caravan energy storage is followed by caravan shipments, the main market is still Europe and the United States side. With the continuous iterative upgrading of the energy storage system, there will be a lot of opportunities for RV energy storage, and the theoretical upper limit of the RV optical storage market is about 193.9 billion dollars.

Home energy storage market: large market space overseas and obvious pain points in emergency power generation.

QY Research’s data show that the global portable generator market size is about 18.7 billion in 2020, and can reach 30.4 billion in 2026, with a compound annual growth rate of 7.2%. Overseas users now have these troublesome things to do with electricity: one, the overseas power grid is not as stable as the domestic one, and the cost of electricity is high, with the American Society of Civil Engineers reporting a total of more than 3,500 power outages in 2015, averaging 49 minutes per outage. Second, to deal with this problem, overseas homes are now typically equipped with emergency power generation, but it’s costly, noisy and polluting. The benefits of home energy storage are stable power consumption, low cost, and policy subsidies.

The main development market for home energy storage is Europe, and most of its system is based on electrochemical energy storage.CNESA’s cumulative data for 2018 shows that in electrochemical energy storage, the user side accounts for the bulk of the total, with a proportion of 32.6%. Electrochemical energy storage can also be subdivided into lithium-ion batteries and lead-acid batteries, with lithium-ion batteries being the main ones.2022 CNESA data suggests that lithium-ion batteries account for 88.8%, and lead-acid batteries for 10%. The information released by CNESA says that in 2020, the market size of home energy storage will be $7.5 billion, and the cost of home energy storage system released by BNEF in 2020 will be $431 per kWh, which makes it possible to figure out that in 20 years, the installed capacity of home energy storage will be 17.4GWh. According to the number of households and the average capacity demand of home energy storage (assuming that it will be 15kwh) in the global world, then the theoretical market According to the global household and the average capacity demand of household energy storage (assuming 15kwh), the theoretical market space is at least more than 1000GWh, which is a lot of space.
