Why is 7kW the most popular ev charging pile for new energy vehicles?

Let's give the answer first, because after comprehensive consideration, 7kW charging pile is the most economical, efficient, practical and worry-free.

First, let's understand what the power of charging piles is?

At present, the main powers on the market are 7kW, 11kW, 21kW, 40kW, 60kW, 80kW, 120kW, 160kW, 180kW, 240kW, 300kW, 360kW, etc. Among them, 40kW and above are generally DC charging piles, which are not suitable for home use, while AC charging piles generally include 7kW, 11kW, and 21kW.

As a home charging pile, AC charging piles are generally selected. The specific reasons are:

1) Less damage to the battery;

2) Charging at home is generally done at night, so there is enough time to charge the car, and the speed requirement is not high;

3) AC charging piles are cheap and easy to install.

The power of home charging piles mainly includes 7kW, 11kW, and 21kW. Judging from the sales of home charging piles, 7kW is the most popular among users, which means that it is most suitable for the charging life of electric car owners. The main reasons are as follows:

1. High adaptability

The 7kW home charging pile is a charging device designed for electric vehicles with a maximum output power of 7 kilowatts. For the 7kW home charging pile, its charging gun interface is designed as 7 holes, which can be used for 99% of new energy vehicles on the market, so there is no need to worry that your car interface is not applicable, almost all can be charged.

2. Low voltage requirements

Generally speaking, it is difficult to apply for three-phase electricity in the community for home use, and a transformer must be used. The whole project is relatively large, and the community can generally only use the 220V/230V/240V voltage of the city power. Therefore, the 7KW charging pile uses a voltage of 220V, which is very suitable, and it is easier to install and use.

3. Economical and affordable

Using a 7kW charging pile means charging 7 kWh of electricity in one hour in theory. If you set the charging to start at 11pm, according to the slowest charging speed, it can be fully charged at 5am the next day.

This charging time is generally the off-peak time in various places, and the electricity bill is lower. And this also matches the time when most car owners use their cars, charging at night and using the car during the day.

Another advantage of 7kW charging piles is low cost. The charging piles sold in the market are basically priced at around 200~400 yuan, which is much lower than the high-power charging piles.

Returning to the technical level, the charging speed of charging piles exceeding 7kW is indeed faster, but it has lost a certain meaning, because the performance exceeds the standard, and the user's perception is almost not improved.

For new energy vehicle owners, the most suitable is the 7kW home charging pile, which can be fully charged overnight. If there is a temporary charging demand, the nearby commercial charging station can also provide a charging speed of 120kW, which can fully charge a car in 30 minutes to ensure the owner's emergency car needs.

Finally, it is recommended that when purchasing a 7kw home charging pile, consumers should pay attention to the following points:

1. Understand your own charging needs and choose a charging pile with suitable power and type.

2. Choose products from well-known brands and reliable manufacturers to ensure product quality and after-sales service.

3. Pay attention to the safety and reliability of the product to avoid safety hazards caused by purchasing inferior products.
