DC Chargers for Public Stations: Infrastructure & Access

DC Chargers for Public Stations: Infrastructure & Access

6 9 月, 2023

The need for sustainable and environmentally friendly solutions is paramount when it comes to fuel-based transportation. No one can deny the role of electric vehicles (EVs) in this regard. To encourage the widespread use of electric vehicles, setting up EV charging stations is essential.

There are two types of charging stations: grid-based AC power stations and solar-based DC power stations. AC power generation requires grids, which further contribute to the carbon footprint by utilizing fuel. On the other hand, options exist to use solar energy for DC power stations, which contribute to clean and green energy.

Apart from this, DC charging contributes to very fast EV charging. This article will uncover the facts on DC Charging Station, components, installation considerations, and more. Just stick to this article to know everything about DC Charging stations.We also mentioned Smart Charging of Electric Vehicles in the last article, hope it will be helpful to you.

DC Charger

DC Charging Station – Overview

A DC charging station is a charging station that uses DC power to charge electric vehicles. The good thing about this system is that it charges almost 80% battery within just 20 minutes. Unlike Level 1 and Level 2 EV chargers, DC chargers are Level 3 chargers. 

Connectors Used in DC Charging Stations

There are three types of connectors that a DC charging station uses. These connectors are:


The long form of CCS is (Combined Charging System). These connectors allow you to connect them to a DC or AC power source. These connectors come in two variants, including CCS 1 and CCS 2. This opens up an option for compatibility with a variety of electric vehicles. There are two extra pins in CCS type 1 and CCS type 2 to enable faster charging. CCS can handle a power of over 350 kW.


These connectors are popular for fast charging of electric vehicles. CHAdeMO can cope with a power of 400kW. These connectors have 10 pins, which allows you to quickly replenish the charging. 


The term GB/T refers to “National Standard Recommended”. These chargers come with 9 pins and enable the fast charging process. GB/T can easily handle a load of 250kW. 

Components And Their Roles – Public DC Charging Stations Infrastructure

Multiple components make up a DC Charging Station. Get highlights on each component down below:

Power Source

The power source is pivotal for public charging stations, as it supplies the electrical energy to the DC Charging station. Whether you opt for a grid connection or a renewable energy source, it’s essential to ensure its compatibility with your station’s requirements. Please note that the power supply directly influences the charging speed and station capacity, especially crucial for public charging locations aiming to serve a multitude of vehicles.

Charge Controller

The key role of the charge controller is to control the electric charge that goes into the electric vehicle’s battery. It ensures the battery safety and effective charging.

Cables and Connectors

Cables and connectors act as a source of link between the electric vehicle and the charging station. There are different connectors, such as GB/T, CHAdeMO, and CCS. They connect the vehicle with the charger.


As your DC charging station requires DC. You can use the direct current from solar energy or convert AC TO DC. Inverter will help you in this regard. This is because DC power transmits more rapidly into the battery than AC. And batteries require a DC source in most EVs. 

Cooling Source

It is no boner that the DC charging system generates a lot of heat. This can adversely affect the life and efficiency of the charger. Therefore, you need to set up a cooling source to cope with this. 

User Interface

The main function of the user interface is to offer EV drivers the ability to begin, monitor, and control the charging of their EVs. The user interface comprises a touch display, QR Scanner, RFID card, and payment disbursement options. 

Safety System

The safety is the key when working with the EV chargers. Some components ensure optimum safety, such as     

1. Overvoltage protection             

2. Overcurrent protection     

3. Emergency Shutdown             

4. Ground Fault Detection

This system prevents damage and accidents to your vehicles. 

Remote Connectivity and Management

Some DC charging stations come with a remote management system. They do this because of websites and mobile apps. You can control usage, performance, and functioning. 

Supporting Structure

You can set up the supporting structure to ensure the protection of the DC chargers and smooth functioning. The key things in supporting the structure include shelter/canopy mounting poles. This structure can also assist the user effectively and ensure protection from sunlight or rain.

Key Considerations For Setting Up Public DC Charging Stations Infrastructure

To make the DC Charging stations last longer, you need to take care of the following things:

DC Charger

Location Selection

To set up these stations, consider the high-traffic areas such as highways, urban centers, malls, etc. This will make your DC Charging station more visible and accessible.

Charging Speed

Identify the type of EVs you have in your area. Different vehicles have different charging requirements depending on battery capacities. Set up a higher power output DC charging station. This will allow you to attract and convert higher users.

Charging Standards

Make sure to involve multiple charging standards such as GB/T, CHAdeMO, and CCS. If it is not possible, you can use the adapter to cater to the needs of other users. This way, you can serve a wide range of vehicles effectively. 

Number of Chargers

Access the total count of chargers you need to deploy in your area. This will prevent the users from waiting in long lines. Design the Station so you can upgrade it in the future. 

Ensure Ample Space

Make sure to design the DC charging station to cater to sufficient space for multiple vehicles. Ensure convenient maneuvering of vehicles by displaying signs and markings for effective guidance.

Power Supply and Infrastructure

Set up these stations close to the power source to ensure a consistent and optimum power supply to your DC charging stations. Upgradation of the power infrastructure cut off the overloading phenomenon. 


Design your DC charging station in a way that makes it easily accessible. You can maintain clear paths, a user-intuitive interface, and high visibility by banners or signage.

Payment System

While setting up the DC Charging station, you need to set up the multiple payment options. Select the DC charging station that accepts payment through apps, RFID cards, etc. More payment options offer convenience to users when it comes to payment.


To set up your DC Charging station and make it one of the best in class, follow the above considerations and ensure each component. This way, you can get the most out of your DC charging station in terms of revenue.
