"Buying a car and giving away a pile" has gradually faded from people's lives, and household charging piles have become a must buy list for new energy owners. Compared with the original charging pile with "small and expensive" price, more and more new energy owners are focusing on the professional charging pile brand. High cost performance, complete functions, high adaptability, strong sense of appearance design, and high level of protection are the advantages of professional charging pile brands that cannot be ignored! So, do you know what kind of stake your car is suitable for? Today, let's teach you how to choose a suitable household charging pile~

Step 1: Look at the car first

Adaptability of vehicle model

You must ask, aren't charging posts and charging interfaces for new energy vehicles, which are all made according to national standards, 100% compatible with charging? Here is a little knowledge that Xiaozhi popularizes science first. An important indicator of the charging pile is the charging power. [Power refers to the amount of work done by an object in a unit time, and power is a physical quantity describing the speed of work. The higher the power, the faster the charging speed in a unit time.]

The maximum acceptable charging power of different models is not determined by the charging pile, but by the BMS system in the vehicle. In short, if your car can only accept 11KW at most, even if you use 20KW power charging pile, you can only accept 11KW speed.

Here, the cars are roughly divided into three types: l Hybrid cars with small battery capacity, generally 16A and 3.5KW piles can meet the demand; L For hybrid models with large battery capacity or hybrid models with increased program, 32A and 7KW charging piles may be required; L If it is a pure electric vehicle, especially a pure electric vehicle with a range of 400 or more, it needs a 380V 11KW charging pile with higher power.

The home charging environment has learned about the adaptation of the car model, as well as the power conditions of the home community. The 3.5KW and 7KW charging poles are all 220V, so you can apply for a 220V meter, while the 11KW or higher power charging poles are 380V, so you need to apply for a 380V meter.

At present, most residential areas can apply for 220V meters, and villas or self built houses can apply for installing 380V meters. For customers who do not know this information very well, it is recommended to seek help from property management and electricity!

Step 2: Post selection of piles

Charge Point Classification

In fact, in the first step, several different household charging posts have been briefly mentioned. Here we will systemically sort them out:

1. Charging pile classification

You must be familiar with the terms AC pile (commonly known as slow charging) and DC pile (commonly known as fast charging). Xiao Zhi has described the difference between the two in detail. Today, I mainly talk about communication posts with you!

In terms of cost, most of the household charging piles are AC piles. Classified by installation mode, it is mainly divided into two categories: wall mounted AC charging pile and portable AC charging pile.

Wall mounted AC charging piles are the most common household charging piles, which need to be installed in fixed parking spaces. According to the power, mainstream household AC charging piles are 3.5KW, 7KW, 11KW and 22KW.

What does different power mean?

3.5KW means charging 3.5KWH in one hour, equivalent to about 20km

7KW means charging 7 kilowatt hours in one hour, equivalent to about 40 kilometers

11KW means charging 11 kilowatt hours in one hour, equivalent to about 60km

22KW represents 22 kilowatt hour charging, equivalent to about 120km

How to screen charging pile brands

Of course, in addition to choosing the right power, the brand of charging piles is also very important when purchasing third-party charging piles. A good brand means better product quality, more intelligent product functions, and better after-sales service. Do not blindly pursue "low price" and ignore the hidden dangers behind it.

It is suggested to choose a third-party brand with independent R&D and production capacity and perfect after-sales security system. At the same time, even if the power is the same, the charging piles of third-party brands are different in terms of function and quality.

See here, have you basically mastered the skills of purchasing charging posts? The most correct choice is to choose a charging pile that is suitable for you and has guaranteed quality.
