According to the statistical data of the Ministry of Industry and Information Technology, the market share of new energy electric vehicles in 2024 has reached about 50% of the passenger car sales, and the number of new energy electric vehicles continues to grow. Under this background, more and more consumers choose new energy electric vehicles as daily travel tools, which not only reduces carbon emissions but also reduces travel costs. Therefore, new energy electric vehicles are increasingly widely used in urban short trips and long-distance travel.

[0003] However, new energy electric vehicles still face the problem of range anxiety when driving long distances or using outdoors for a long time. The current mainstream charging methods on the market include alternating current charging piles and direct current charging piles, although these charging methods are more common in urban environments, but in remote areas or outdoor scenes, due to the lack of charging facilities, it is difficult to meet the charging needs of users. Especially in outdoor travel, camping and long-distance driving, the endurance problem of new energy electric vehicles is more prominent.

[0004] In order to solve this problem, portable energy storage devices have appeared on the market, users can provide temporary power for vehicles or electrical equipment through portable power supplies. However, these mobile energy storage devices have limited power and insufficient endurance, and when the energy storage device runs out of power, it still needs to find a charging pile to charge, which is difficult to meet the long-term outdoor power supply needs. At the same time, many users need to use some household appliances (such as cooking equipment, lighting equipment, etc.) during outdoor activities, and the existing energy storage devices cannot fully meet this demand in terms of power supply capacity.
