Home Charging Pile Selection, from Beginner to Master



With the popularity of electric vehicles, more and more families are beginning to install home charging piles to make charging their cars more convenient. However, many car enthusiasts are often confused from the selection to installation of charging piles. This popular science issue will teach you how to select and successfully install a high-quality home charging pile.

Determine charging needs and select appropriate power
Generally speaking, there are many choices for the power of household charging piles. The most common ones are 7kW, 11kW, and 21kW, which correspond to different voltage levels, such as 220V and 380V.

Within the maximum charging power of the car, the greater the power of the charging pile, the faster the charging rate and the shorter the charging time. However, it should be noted that when selecting the power of the charging pile, the load capacity of the household circuit and the charging needs of the electric vehicle must be considered. The maximum charging power that new energy vehicles can accept is not determined by the power at the pile end, but by the vehicle end. It should be selected based on the power that your car is suitable for. The bigger the power, the better. If the home circuit load capacity is limited, or the battery capacity of the electric vehicle is small and the charging speed is not required, you can choose a charging pile with a lower power, such as 7kW. On the other hand, if the household circuit load capacity is strong, or the battery capacity of the electric vehicle is large and requires faster charging speed, you can choose a charging pile with higher power, such as 21kW.


Selected brands with equal emphasis on quality and safety

1. Choose the charging pile installation method

We can choose wall-mounted or column-mounted. It is recommended that new energy car owners choose according to their parking space conditions. If it is close to a wall, they can choose a wall-mounted type. If there is no wall, they can choose a column type.

2. Choose a charging pile with high safety
In terms of safety, you should first confirm whether it has protective functions such as waterproof and dustproof, lightning protection, and leakage protection to ensure personal safety. The second is the protection of the charging pile for charging. Whether there is voltage or power protection, it is best to have intelligent temperature control. If the temperature is too high, it will automatically reduce the power or directly cut off the power, which can better protect the equipment and personal safety.

Dongduo electrical charging piles are equipped with ten layers of protection including waterproof and dustproof, lightning protection, grounding protection, overcurrent protection, electrostatic protection, leakage protection, and temperature control protection. Even if they are installed outdoors or used in the open air, there is no need to worry, and they support remote start. , scheduled charging, private pile sharing and other smart functions. In addition, Nanjing Nengrui has also cooperated with Ping An Insurance to insure each charging pile to ensure that car owners have no worries.


Professional installation ensures safety and convenience


1. Choose the charging pile installation method

Prepare identity proof materials, parking space ownership certificate materials (if the parking space is rented for a long time, you can provide the "Parking Space Owner Permit Certificate" or "Parking Space Agreement to Use Proof"), car purchase agreement or invoice, property certification materials ("Agree to Construction" stamped by the property Opinion Letter" Shanghai and other places are the "Registration Certificate for the Installation of Electric Vehicle Charging Facilities").

2. Apply for electricity meter construction and installation

After preparing the above materials, riders can apply offline to the local power grid company or apply online. After application, staff will call back to verify the demand, usually within 2-3 days. After confirming the demand, they will go to the site to conduct an inspection, issue an installation plan, and install a special meter.

3. Construction and installation of charging piles

After the meter is installed, it is time to install the charging pile. It should be noted that the professionalism of the installer is related to the safety and worry-free subsequent use of the charging pile. Therefore, everyone must choose a regular installation service provider to ensure compliance with the installation process and avoid ground faults.
