Are new energy vehicle home charging piles slow charging?

At present, the charging power of household charging piles on the market is generally divided into 7kW, 11kW, and 21kW. There are no restrictions on the vehicle end, and when conditions such as power and temperature are supported, it means that these charging piles can charge the power battery by 7 degrees per hour. , 11 degrees, 21 degrees of electricity. These are generally AC stakes, since household electricity is all AC.

There are also low-power DC charging piles. For example, MOREDAY has a 30kW low-power DC charging pile that supports household use.

How to choose the charging power?

How to choose 7kW, 11kW and 21kW? It’s not that the higher the better.

In addition to 7kW supporting 220V single-phase power, both 11kW and 21kW require 380V three-phase power, so before deciding which power charging pile to choose, you need to communicate with the power grid and the property to see if they support the installation of 380V three-phase power.

Does the car support

Not all models support various powers. For example, most models such as Ideal, Weilai, Xiaopeng, and Roewe support 220V32A7kW AC charging at most, so only 220V7kW charging piles can be installed.

Tesla model3, Tesla modelY, BMW iX3, and Audi etron can support up to 380V16A11kW AC charging. Even if a 21kW charging pile is installed, it can only reach 11kW of power when charging.

Some models also support 380V 21kW AC charging.

When choosing a charging pile, which pits should be avoided?

01. Don’t buy OEM brands. Some brands just find a small factory to sign a processing agreement, and then affix the brand of the seller. This kind of brand lacks research and development strength, and if there is a problem with the product, it can’t be solved in time, or even can’t be solved.

Only consider brands with independent research and development and production, which are more secure in terms of after-sales and insurance. Star Charge has independent R&D and production capabilities.

MOREDAY has the strength of independent research and development and production. The annual shipment of charging piles is among the best, and it also has a professional operation and maintenance and after-sales team.

02. Don’t blindly care about the price and ignore the safety. Many people think that the charging pile can be charged, but in fact, they should also pay attention to its safety.

In terms of dustproof and waterproof charging piles, each charging pile has a protection level marked on the nameplate of the charging pile. The first digit after IP is the dustproof rating, and the second digit is the waterproof rating. The larger the number, the higher the protection rating.

The general standard is IP54, so as to effectively prevent dust from entering the pile. At the same time, it can withstand low-pressure water spray for 3 minutes, and also has the ability to protect against vertically falling water droplets, so that it can also be charged outdoors in ordinary rainy days.

However, some brands of charging piles do not meet such standards, and dust will enter and affect charging safety, or cannot prevent rainwater from entering the pile, causing charging accidents.

The charging pile is a high-power electrical appliance. We should be careful about its selection, otherwise an accident may cause huge losses.
