[0002] At present, RVs have opened up in the domestic market and are gradually appearing in the public eye. RV camps are also being built at a faster pace. Each manufacturer has its own characteristics in terms of craftsmanship, design, and layout of RVs, but the power supply of RVs has always been a major problem that stops consumers from purchasing.

[0003] At present, the concept of RV is more to make the user experience as comfortable as living at home, so there will be more electrical appliances in the RV. When all are enabled, the load is large, and the voltage required at the load end is different. The battery capacity on the traditional RV is also relatively small, which cannot meet the user's usage requirements, resulting in insufficient power. Electricity is a necessity for home and car, and it is naturally indispensable in RVs. As a combination of house and car, the power in the RV is different from the power in the house. The existing main modes are 12V DC and 220V AC. Among them, 12V DC is stored in the lead-acid battery of the RV, and 220V AC needs to be inverted from the lead-acid battery. The lead-acid battery on the body can store limited power, and the charging method is single. Utility Model Content
