Description

A pure electric caravan

technical field

The utility model relates to a sojourn car, in particular to a pure electric sojourn car, which belongs to the technical field of vehicle equipment application.

Background technique

With the development of the economy and the progress of the society, the material life of our people has been greatly improved. People now pay great attention to the freedom of the spirit. In order to stay away from the hustle and bustle of the big cities and avoid the smog, traveling by car is becoming more and more popular. , RVs have developed rapidly in recent years. RVs are called "homes on wheels". They have the two functions of "house" and "car". For a comfortable travel experience, various electric living facilities need to be installed in the caravan. These living facilities need to use a lot of electricity. However, due to space constraints, the battery capacity of the existing fuel-powered caravan is very limited, often only a few hundred watt-hours , taking the air conditioner used in RV as an example, the batteries equipped with existing fuel-powered RVs generally can only support the air conditioner for a few hours or even less, which is difficult to meet the requirements of users. Although the existing fuel-powered RVs can be used in RV camps The external mains power supplies power for various living facilities on the car, but the reality that has to be faced is that the construction speed and coverage of RV camps are far behind the needs of users.

With the development of science and technology, electric vehicle technology and battery technology have also made great progress. Electric vehicles are becoming more and more popular. Because electric vehicles do not have fuel engines, they can be equipped with large-scale battery packs and store a large amount of electric energy. The existing Electric vehicles are generally equipped with batteries of more than 20 kWh. In addition, the popularity of electric vehicle charging piles is very fast, and the coverage area is getting wider and wider. Users can replenish electric energy through electric vehicle charging piles in a timely manner.

In addition, all kinds of RV-specific living facilities installed in RVs generally use DC power, so the cost is high. Taking air conditioners as an example, the price of DC air-conditioning systems for RVs is as high as tens of thousands of yuan, while the price of household air conditioners using AC power is generally 2,000 to 3,000 yuan. .

Therefore, it is necessary to develop a pure battery that can make full use of the existing battery technology of pure electric vehicles and electric vehicle charging piles to supply power to various household AC living facilities used in RVs, and has the advantages of low travel costs, environmental protection, comfort, and low noise. An electric caravan is very necessary, and the pure electric caravan also has important application prospects.
