How does Tesla solve the charging anxiety? What are the advantages of car charging?

The biggest change from tanker to tram is charging anxiety. As a person who likes planning, I am super worried about whether there will be a power outage, but since I got into the car charger, I am very comfortable driving out. First, the advantages of car charging:

Long-distance travel does not need to find a hotel with a charging pile, as long as there is a socket, you can charge it. Not only can it be taken with the car, but it can also be installed in a fixed position for family use. If the socket end is waterproof, it can also be used in outdoor camping. If there are three or five friends traveling together, you can not only charge Tesla, but also use other new national standard new energy vehicles, which saves the trouble of finding a charging pile ~ When Tesla has no power, you can plug it into Li one to charge Tesla reversely, which is simply an emergency artifact. When charging, overheating can also automatically cut off power. Second, how to choose three specifications?

3kW car charger. 799 yuan. The most cost-effective, most suitable for carrying out. But the charging speed is the slowest. Input voltage: single-phase 220V. It takes 22. 1 hour 3 to fill a model. It is more suitable for emergency use when going out. 7kW car charger. 1899 yuan. The price is a little more expensive, so it can be used at home and outside. Input voltage: single-phase 220V. It takes 10.5 hours3 to fill a model. 1 1kW car charger. 2399 yuan. It is only 7kW more expensive than 500 yuan, but the charging speed is greatly improved. It can be used as a household charging pile, and has a high cost performance compared with a fixed charging pile. Input voltage: single-phase 220V, three-phase 380V. It can also be used when going out, which is convenient to carry. Suitable for all kinds of new energy vehicles. One-piece charging gun, 10 meter long cable, bid farewell to the trailer. It takes 6.5 hours to fill a model. Third, summary:

There is a charging pile at home, which is only used outside, and it can be charged with 3kW, which is the most cost-effective. There is no charging pile at home, so you can use it at home when you go out. 1 1kW is faster and more convenient to charge with the car. You can't connect 380V three-phase electricity at home, you can only connect 220V, and you want to charge at home. 7kW car charging, 220V charging efficiency is high.
